Sahara Ave. Suite 120 Las Vegas, NV 89117 Certifying Officer Name and Title: Timothy Sutton, Town Manager, Town of Pahrump Consultant (if applicable): BEC Environmental, Inc. 7241 W. Sahara Ave. Suite 120 Las Vegas, NV 89117 Project Location 4670 South Nevada Highway 160 Pahrump, Nevada 89048 Description of the Proposed Project [24 CFR 50.12 & 58.32; 40 CFR 1508.25]: The proposed project is to continue the phased development of the Pahrump Fairgrounds using U.S. Department of Housing and Urban Development (HUD) Community Development Block Grant (CDBG) and other funds. The Pahrump Fairgrounds Development Area planned expansion activities include developing a stormwater detention basin and associated drainage channels, the addition of paved parking to facilitate expanded community use, and the construction of a single story 15,000 square-foot Community Development Center. ---PAGE BREAK--- The detention pond would be constructed as specified in the Pahrump Fairgrounds Drainage Study and Flood Control Design Plan, prepared by Dyer Engineering in June 2019 (Appendix 2 – Flood Control Information). The detention pond was designed to store the 100-year volume and would allow additional storage for current conditions until the future build-out phase is implemented. The detention pond would measure 250 feet wide by 350 feet in length and 3 feet deep with 3:1 side slopes and lined with 4-inch riprap. The total capacity of the pond would be 6.4 acre-feet (2.085 million gallons). The outlet structure would consist of a 12-inch corrugated metal pipe (CMP) that would extend to a channel as its primary conveyance. A spillway would also be constructed at the 25-year elevation allowing overflow conveyance of the 100-year event. The proposed channels would be positioned and sized to accommodate conveyance of the 100- year event for partial and future build-out conditions. The channels would collect runoff from the north side of the parcel and outlet into the detention pond, positioned in the southwest corner of the property, as depicted in Image 1 – Drainage Study and Flood Control Site Plan, below. The outlet channel would convey the water from the detention pond to Gamebird Ditch. Additional specifications are available in the complete Pahrump Fairgrounds Drainage Study and Flood Control Design Plan (Appendix Image 1 – Drainage Study and Flood Control Site Plan ---PAGE BREAK--- The approximate planned location of the parking area and the Community Development Center are depicted on Figure 1 - Project Location Map (Appendix 1 – Maps). Project Location: The proposed development is located at 4670 South Nevada Highway 160 in Pahrump, Nevada 89048. The project area is on a portion of Nye County’s Assessor’s Parcel Number (APN) 027- 741-01, the subject site comprising a 75.5-acre portion of the 427.24-acre parcel within portions of Section 32 and 33 of Township 20 South, Range 54 East, Mount Diablo Base Meridian. The subject site includes an unpaved portion of the multipurpose fields developed during a previous step of the Pahrump Fairgrounds expansion, undeveloped fields to the western edge of the parcel, existing drainage channels, and areas in which additional surface water drainage channels are planned to be constructed. Statement of Purpose and Need for the Proposal [40 CFR 1508.9(b)]: The purpose of the proposed project is the provide a foundation for future development of the Pahrump Fairgrounds. A portion of the 427-acre parcel is within a Federal Emergency Management Agency (FEMA) Special Flood Hazard Area A, without base flood elevation determined, as depicted on Figure 2 – FEMA Flood Zone Map (Appendix 2 – Flood Control Information). Installation of the detention basin and channels is a necessary prerequisite for future expansion of the Pahrump Fairgrounds. The proposed project will be funded by HUD CDBG funds, Title I of the Housing and Community Development Act of 1974 (42 U.S.C. 5301, et seq.), with the purpose of developing a stormwater detention basin and associated water channels. Additional development of a paved parking area and a Community Development Center will be funded during future phases of development. The future development of the parking area and Community Development Center, located approximately in the southeastern portion of the parcel, will promote recreational and tourism opportunities in this rural community. Based on the economic development matrix provided by the Governor’s Office of Economic Development, Nye County anticipates this project will create 14 long-term jobs in the following categories: convention and trade show organizers, landscape services, and full-service restaurants. In addition, Nye County anticipates many additional short-term jobs for future events held at the Fairgrounds. Existing Conditions and Trends [24 CFR 58.40(a)]: The project is located at 4670 South Nevada Highway 160 in Pahrump, Nevada 89048, as shown on Figure 1 – Project Location Map in Appendix 1.

STATUTES, EXECUTIVE ORDERS, AND REGULATIONS LISTED AT 24 CFR 50.4 & 58.5 Clean Air Clean Air Act, as amended, particularly section 176(c) & 40 CFR Parts 6, 51, 93 Yes No Finding of No Impact. Areas of the country where air pollution levels persistently exceed the National Ambient Air Quality Standards (NAAQS) may be designated as areas of “nonattainment” by the Environmental Protection Agency (EPA). The EPA Green Book provides detailed information about NAAQS designations, classifications, and nonattainment status. Nye County is not listed in the Criteria Pollutant Nonattainment Summary Report, the Nevada Nonattainment/Maintenance Status for Each County by Year for All Criteria Pollutants, or the 8-Hour Ozone ---PAGE BREAK--- Non-Attainment Areas in Appendix 5 – Clean Air. Permits for dust may be required and would be issued by Nye County or the Town of Pahrump, if necessary. Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 3, 2019. Coastal Zone Management Coastal Zone Management Act, sections 307(c) & Yes No Not applicable to this project. Coastal Zone Management resources will not be impacted. The State of Nevada is not a coastal state within or bordering an ocean, the Gulf of Mexico or the Great Lakes; therefore, the state does not contain a designated Coastal Zone, as shown in the Coastal Barrier Resources Map found in Appendix 4. Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 3, 2019. Contamination and Toxic Substances 24 CFR Part 50.3(i) & 58.5(i)(2) Yes No Finding of No Impact. A Phase I Environmental Site Assessment (ESA) of the project area was completed on October 7, 2019. The assessment revealed no evidence of recognized environmental conditions in connection with the subject site, as stated in the Phase I ESA found in Appendix 6 – Contamination and Toxic Substances. Determinations made within the Phase I ESA by Rachel Schlick, Environmental Scientist, BEC Environmental Inc., September 23, 2019. Endangered Species Endangered Species Act of 1973, particularly section 7; 50 CFR Part 402 Yes No Finding of No Impact. The project area is located within a predominantly vacant, undeveloped parcel. The immediately surrounding property includes lots graded for residential development and Highway 160. The US Fish and Wildlife Service (USFWS) identified two endangered species and one threatened species protected under the ---PAGE BREAK--- Endangered Species Act in the general vicinity of the project area: southwestern willow flycatcher (Empidonax traillii extimus), Yuma clapper rail (Rallus longirostris yumanensis), and Mojave desert tortoise (Gopherus agassizii). Southwestern willow flycatcher and Yuma clapper rail are not expected to be impacted by the proposed project because the subject site does not contain suitable habitat. There is no riparian or marsh areas within the subject site. The USFWS identified no critical habitat within the project area, as stated in the USFWS Official Species List found in Appendix 7 – Endangered Species. A biological survey was conducted on September 3, 2019, on the western half of the project site, on September 18, 2019, on the eastern half of the project site, and on November 5, 2019, to further search for desert tortoise or sign of their presence within areas designated as Potential Tortoise Habitat within the parcel but outside the project area. Five burrows were observed within the project area which had the potential to be considered constructed or used by tortoises. However, three of these burrows were clearly abandoned, mostly-collapsed predator burrows, and two burrows had collapsed to the extent that an assessment of what species may have constructed or inhabited it was not possible. No other sign of tortoise use was present scat, tracks, or other indicators) within or adjacent to any of these burrows, or throughout the project area. In addition, no desert tortoise scat, carcasses, or other indicators of past use of the site by tortoises were observed. Based on the lack of suitable habitat on the project site; the marginally suitable, apparently unoccupied habitat within the remaining portions of the parcel; and effective isolation of the site from suitable habitat beyond the parcel, a Finding of No Effect on desert ---PAGE BREAK--- tortoises was made within the Biological Evaluation (BE) dated January 6, 2020, in Appendix 7. Nye County concurred with a Finding of No Effect determination for the Mojave desert tortoise on January 14, 2020. Determinations made within the Biological Evaluation by Danny Rakestraw, Senior Scientist and Authorized Desert Tortoise Biologist, BEC Environmental Inc., January 6, 2020. Explosive and Flammable Hazards 24 CFR Part 51 Subpart C Yes No Finding of No Impact. The proposed project does not include a hazardous facility (a facility that mainly stores, handles, or processes flammable or combustible chemicals such as bulk fuel storage facilities and refineries). No above-ground storage tanks or other evidence of explosive or flammable hazards were observed on or adjacent to the subject site during the Phase I ESA site visit on September 3, 2019, in nor the subsequent site visit on September 18, 2019. There are no current or planned stationary above ground storage containers of more than 100-gallon capacity containing common liquid industrial fuels or containers of hazardous liquids or gases of any size currently or planned to be on the subject site (Appendix Determination made within the Phase I ESA by Rachel Schlick, Environmental Scientist, BEC Environmental Inc., September 23, 2019. Farmlands Protection Farmland Protection Policy Act of 1981, particularly sections 1504(b) and 1541; 7 CFR Part 658 Yes No Not applicable to this project. The US Department of Agriculture, Natural Resources Conservation Service, has designated the soils from the project as Farmland of Statewide Importance. The US Department classifies any location “that are best suited to food, feed, fiber, forage, and oilseed crops”, is registered as protected. The project site is located on a parcel currently zoned as residential and planned ---PAGE BREAK--- for commercial development. Based on current zoning, the Farmland Protection Act does not apply (Appendix 8 – Farmlands Protection) . Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 13, 2019. Floodplain Management Executive Order 11988, particularly section 2(a); 24 CFR Part 55 Yes No Finding of No Impact. The project area is not located within a Federal Emergency Management Agency (FEMA) identified Special Flood Hazard Area (SFHA). The Pahrump Fairgrounds Development Area is located within Zone X, outside the 0.2- percent-annual-chance-floodplain, as depicted on Figure 2 – FEMA Flood Zone Map in Appendix 2. Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 13, 2019. Historic Preservation National Historic Preservation Act of 1966, particularly sections 106 and 110; 36 CFR Part 800 Yes No Consultation/Review Procedures Required. Section 106 Consultation was conducted with the Nevada State Historic Preservation Office (SHPO). There were no historic properties observed on the subject site. Nye County Assessor parcel records were reviewed for each parcel located, wholly, or partially, within the Area of Potential Effect (APE); none of these properties had been recommended for listing in the National Register of Historic Places based on a review of the Nevada Cultural Resource Information System (NVCRIS) Urban Architectural Resources database. On January 9, 2020, SHPO recommended an archaeological inventory of the direct physical APE be completed by a Secretary of the Interior-qualified archaeologist to survey and update previously recorded cultural resources (Appendix 9 – Historic Preservation). A Cultural Resources Study was performed by SWCA Environmental Consultants ---PAGE BREAK--- (SWCA) (Appendix 9) during April 2020, to conduct a site revisit and update the site record for the previously recorded site within the APE. SWCA recommended the site ineligible for the National Register of Historic Places (NRHP) and a finding of No Historic Properties Affected was recommended. Determination of a finding of No Historic Properties Affected made by Nye County, April 28, 2020. Concurred by Robin K. Reed, State Historic Preservation Office, May 29, 2020. Noise Abatement and Control Noise Control Act of 1972, as amended by the Quiet Communities Act of 1978; 24 CFR Part 51 Subpart B Yes No Finding of No Impact. The HUD Day/Night Noise Level (DNL) calculator was used to determine the project noise. The DNL calculation worksheet and traffic count data are included in Appendix 10 – Noise Abatement and Control. Two values were calculated based on the proposed building proximity to major roads Highway 160 and Hafen Ranch Road, see Appendix 1, Project Location Map. No airport or railways were within 2,000 feet of the subject site and were therefore not considered noise contributors. The calculation combined Nevada Division of Transportation (NDOT) average annual daily traffic (ADDT) counts for Highway 160 west of the subject site, Hafen Ranch Road south of the subject site. The DNL contribution from traffic on Highway 160 was 39.8 decibels (dB), Hafen Ranch Road was 19.7 dB. The combined expected site noise level from road sources was 47.8 dB (Gamebird Road was significantly closer to subject site but had no AADT readings and therefore was not included in the calculation). The combined noise level, under 65 dB, is considered “Acceptable” under HUD requirements for outdoor noise levels. Information on Highway 160 and Hafen Ranch Road was obtained from the State of Nevada Vehicle Classification Distribution ---PAGE BREAK--- Report 2018, Appendix 10, Nye County Traffic Report. Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 3, 2019. Sole Source Aquifers Safe Drinking Water Act of 1974, as amended, particularly section 1424(e); 40 CFR Part 149 Yes No Finding of No Impact. The US EPA, Region 9, has not designated any sole source aquifers in the state of Nevada, as shown in the US EPA Region 9 Sole Source Aquifer map found in Appendix 11 – Sole Source Aquifers. Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 3, 2019 Wetlands Protection Executive Order 11990, particularly sections 2 and 5 Yes No Finding of No Impact. The USFWS National Wetlands Inventory Mapper web application identified no wetlands or riparian areas in the vicinity of the project area. Three ephemeral riverines were depicted east (and outside) of the project area but within the larger parcel on the USFWS National Wetlands Inventory Map in Appendix 12 – Wetlands Protection. Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 3, 2019. Wild and Scenic Rivers Wild and Scenic Rivers Act of 1968, particularly section 7(b) and Yes No Finding of No Impact. There were no designated Wild and Scenic Rivers near the subject site; Nevada has approximately 141,796 miles of river, but no designated Wild and Scenic Rivers, and no Study Rivers, as shown in Appendix 13 – Wild and Scenic Rivers. Nevada does not contain any Nationwide Rivers Inventory identified river segments which could potentially qualify as national wild, scenic, or recreational river areas. Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 3, 2019. ---PAGE BREAK--- ENVIRONMENTAL JUSTICE Environmental Justice Executive Order 12898 Yes No Not Applicable to this Project. The proposed project is not expected to have a disproportionate effect on low-income or minority populations. The subject site is located within an area containing a 14% minority population. Thirty-nine percent of households within 0.68-mile radius were classified as low- income, with and income of less than 50,000 per year (EJScreen ACS Summary Report). See Appendix 14 – Environmental Justice. Determination made by Alana Holt-Hall, BEC Environmental, Inc., on September 3, 2019. Environmental Assessment Factors [24 CFR 58.40; Ref. 40 CFR 1508.8 &1508.27] Recorded below is the qualitative and quantitative significance of the effects of the proposal on the character, features, and resources of the project area.

Credible, traceable, and supportive source documentation for each authority has been provided. Where applicable, the necessary reviews or consultations have been completed and applicable permits of approvals have been obtained or noted. Citations, dates/names/titles of contacts, and page references are clear. Additional documentation is attached, as appropriate. All conditions, attenuation or mitigation measures have been clearly identified. Impact Codes: Use an impact code from the following list to make the determination of impact for each factor. Minor beneficial impact No impact anticipated Minor Adverse Impact – May require mitigation Significant or potentially significant impact requiring avoidance or modification which may require an Environmental Impact Statement Environmental Assessment Factor Impact Code Impact Evaluation LAND DEVELOPMENT Conformance with Plans / Compatible Land Use and 1 The Pahrump Fairgrounds Development Area is predominately an undeveloped property in Nye County with a ---PAGE BREAK--- Zoning / Scale and Urban Design multiphase development plan. The first phase of development included the construction of an access road, parking area, and fenced-multipurpose field. Phase two comprised the installation of a groundwater well to support Fairground water supply needs. Phase three was the drainage study and flood control design plan. Phase four will include the construction and installation of the drainage basin and water channels based on the findings from phase three. To address lack of organized recreational opportunities for community youth, the 2014 Pahrump Regional Planning District Master Plan Update included development of the Pahrump Fairgrounds to include ball fields, exhibit halls, and a rodeo arena. This master plan designated the Pahrump Fairgrounds Development area as a proposed park. To support the ongoing expansion of the Pahrump Fairgrounds, Nye County instituted a Pahrump 1/10 Fairgrounds Room Tax Special Revenue Fund. Future phases will include the construction of a Community Development Center and additional parking for the Fairgrounds. This development may improve access to recreational activities and tourism in the community. Jimmy Martinez, Safety Specialist, Pahrump Building & Grounds, concurred September 25, 2019. Albert Cammarata, Building Official, Nye County Planning Department, concurred September 25, 2019. Hazards and Nuisances including Site Safety and Noise 3 The Phase I ESA (Attachment 6) identified no recognized environmental conditions. The development of the drainage basin and associated channels, parking lot, and community building would generate noise noticeable in the surrounding environment that may exceed the allowable thresholds. Standard construction noise minimization techniques generally include the time-of-day operation limitations, and placement of construction equipment such that noise effect is minimized. Due to the parcel being within a mostly undeveloped neighborhood, this project will not pose a significant impact to noise levels. No known explosive or flammable hazards were identified on this parcel and the proposed action does not include the installation of aboveground or underground storage tanks. ---PAGE BREAK--- Jimmy Martinez, Safety Specialist, Pahrump Building & Grounds, concurred September 25, 2019. Albert Cammarata, Building Official, Nye County Planning Department , concurred September 25, 2019. Energy Consumption 2 The development of the drainage basin and associated channels is expected to have no impact on the ability of the power company to provide electric services to the area. The additional parking area may encourage additional vehicular traffic to the fairgrounds. However, the additional services provided for the community may result in fewer trips out of the Pahrump Valley for recreational activities. The community center architectural plans will consider potential energy saving measures related to climate, sun, and wind. Environmental Assessment Factor Impact Code Impact Evaluation SOCIOECONOMIC Employment and Income Patterns 1 The proposed project will enhance economic development, as outlined in Fairground Detention Basin grant, by creating thirteen full-time long-term jobs and in addition creating construction jobs related to the development of the Pahrump Fairgrounds. The proposed project is anticipated to generate 14 full-time job opportunities in addition to many short-term entrepreneurial opportunities for vendors at the Fairgrounds. Demographic Character Changes, Displacement 2 The subject site, which is located within zip code 89048, is an area where 30% of the population fall below the poverty line, according to EPA EJSCREEN. The project area is currently vacant and predominately undeveloped. Low-income or minority populations are anticipated to be indirectly affected, as the development of the Community Development center and additional parking will increase opportunities in the rural community while also increasing recreational and tourism in the area. The development of the Pahrump Fairgrounds will provide an opportunity for the sense of community to grow. The development of the drainage basin and water channel is a prerequisite for the development of all future phases. ---PAGE BREAK--- Environmental Assessment Factor Impact Code Impact Evaluation COMMUNITY FACILITIES AND SERVICES Educational and Cultural Facilities 2 The development of the drainage basin and channels, parking area, and community center will not impact educational facilities because it will not have an impact on the projected student population. JG Johnson Elementary School is located 9.7 miles northwest of the subject site. It has a total of 491 students and a student-teacher ratio of 21:1. Pahrump Valley High School is located 9.3 miles northwest of the subject site. It has a total of 1,225 students enrolled. Commercial Facilities 1 The Pahrump Fairgrounds Development Area is located at the southern end of the Town of Pahrump along Highway 160. The closest commercial facility is the Spring Mountain Motor Resort and Country Club, approximately 0.52 miles from the project area across Highway 160. The development of the drainage basin and water channels will not likely influence the success of nearby commercial facilities. However, the future project development of parking lot and Commercial Center Development may contribute to the increase in economic and residential development in vicinity. Health Care and Social Services 3 The Town of Pahrump has multiple medical centers; Desert View Hospital, Southwest Medical Pahrump Healthcare, Reiner Medical, and the V.A. Clinic. Desert View Hospital is the largest of the four, located 9.7 miles northwest of the project site. The closest medical center is the Southwest Medical Pahrump Healthcare, approximately 5.9 miles northwest of the project site. Reiner Medical is located approximately 5.9 miles northwest of the project site. V.A. Clinic is located approximately 9.8 miles northwest of the project site. Child & Family Services Department is located 6.0 miles northwest of the project site. The development of the drainage basin and channels will have no impact on healthcare or social services. The additional parking area and community services building may result in increased use of the Pahrump Fairgrounds. However, the majority of site users are anticipated to be residents of Pahrump and the surrounding areas. Therefore, the proposed project will have no impact on the existing healthcare services capacity and ability to accommodate the community. ---PAGE BREAK--- Solid Waste Disposal / Recycling 2 The proposed development of the Pahrump Fairgrounds will result in an increase waste produced. Waste generated during the installation of the detention basin, and construction of the parking area and community building is not anticipated to be hazardous. Waste generated due to increased use of the Pahrump Fairgrounds is not anticipated to be hazardous. Additionally, the waste produced is not anticipated to overburden the landfill. Wastewater / Sanitary Sewers 2 The sanitary sewer system operated by Great Basin Water Co. services the project site and surrounding areas. The installation of the detention basin and channels will not impact the wastewater/sewer system. Once constructed, the parking area and community building will result in an increase in the wastewater generated. However, the proposed project will not result in an increase in the population. As such, the proposed project will have no effect on the capacity of the sewer system. Water Supply 2 Great Basin Water Co. is responsible for the potable water supply for the subject site. The distribution system is comprised of five wells located in Central Pahrump. The addition of drainage basin and channels is not anticipated to have a significant impact on the water supply or quality. The addition of parking area and Community Development Center is not expected to significantly impact current water usage level or treatment operations because the proposed construction will not result in an increase in significant consumption of the community’s available water supply. Public Safety - Police, Fire and Emergency Medical 3 The emergency room at Desert View Hospital is located 9.7 miles northwest of the project site. The Pahrump Valley Fire and Rescue Station 3 is located approximately 7.6 miles southwest of the subject site. The Nye County Sheriff’s Office is located 8 miles northwest of the subject site. The proposed project will not result in a substantial increase in the need for emergency services in Pahrump; existing services would cover any additional incidents related (directly or indirectly) to the drainage basin and channels, parking area, and Community Development Center. Parks, Open Space and Recreation 1 The proposed development of the drainage basin and channels; parking area; and Community Development Center will provide additional parks, open space, and recreation opportunities for Pahrump residents. ---PAGE BREAK--- Arlette Ledbetter, Tourism Director, Executive Assistant, concurred September 25, 2019. Transportation and Accessibility 2 Development of the drainage basin and channels parking area and the Community Development Center will improve accessibility to Pahrump residents by providing additional parking to utilize existing park services. The additional traffic is not anticipated to result in traffic delays for other drivers. Environmental Assessment Factor Impact Code Impact Evaluation NATURAL FEATURES Unique Natural Features, Water Resources 2 There are no unique natural features or water resources on the parcel or in the area potentially impacted. Vegetation, Wildlife 3 Temporary and minor impacts to native wildlife are expected due to the proposed ground disturbance associated with the development of drainage basin and associated channels, parking area, and Community Development Center. In support of this BE, BEC requested data on species potentially affected by the project from the Nevada Department of Wildlife (NDOW) on August 28, 2019 (Appendix NDOW reported elk actively occupy habitat within a four-mile buffer area, but not within the Project Site. Additionally, various species of raptors were reported to possibly reside in the vicinity of the Project Site and have distribution ranges within a four-mile buffer. These include: American kestrel, bald eagle, barn owl, burrowing owl, Cooper's hawk, ferruginous hawk, flammulated owl, golden eagle, great horned owl, long-eared owl, merlin, northern goshawk, northern harrier, northern saw-whet owl, osprey, peregrine falcon, red-tailed hawk, rough-legged hawk, sharp- shinned hawk, short-eared owl, Swainson's hawk, and turkey vulture. Species which have been directly observed in the vicinity of the Project Site include bald eagle, burrowing owl, golden eagle, merlin, prairie falcon, and rough-legged hawk. NDOW also identified ten nests for eagles, hawks, falcons, and owls known to be present within ten miles of the Project Site. BEC also consulted with the Nevada Natural Heritage Program (NNHP) on August 29, 2019 (Appendix No at- risk taxa were reported within the Project Site or within a two-kilometer radius surrounding the project. NNHP ---PAGE BREAK--- reported habitat may be available for the following Nevada Bureau of Land Management (BLM) Sensitive Species: Mexican free-tailed bat (Tadarida brasiliensis), and the Federally Threatened Taxon, Mojave desert tortoise. As part of the coordination and data gathering process, the USFWS and NDOW reaffirmed that migratory birds, including raptors, are present in the area and are protected. Migratory birds are and will be present on the Project Site throughout the year, including the breeding season, and therefore, may be impacted by the proposed project. Migratory birds use vegetation in this region for foraging and nesting and are likely to use the Project Site in the same manner. The species composition in the area likely varies seasonally. While surveys for migratory birds and bird nests were not conducted, migratory birds were observed in the Project Site during multiple site visits, including common raven (Corvus corax), chipping sparrow (Spizella passerina), white crowned sparrow (Zonotrichia horned lark (Eremophila alpestris), and loggerhead shrike (Lanius ludovicianus). One ball-shaped nest, indicative of being constructed by a Verdin (Auriparus flaviceps), was observed in the Project Site. No sign of burrowing owls or raptors nests were observed. Incidental mortality or displacement among small, common animals may occur on the site during clearing and construction.

This report will provide the needed drainage analysis and preliminary flood control design with the recommended features to implement the community’s vision of the fairgrounds. The fairgrounds will provide public amenities that can be utilized throughout the year. Study Area The Town of Pahrump is located in Nye County about 50 miles east of Las Vegas, NV. The Pahrump Fairgrounds is located off Highway NV-160 and Gamebird Road, consisting of a 427- acre parcel. Figure 1 - Study Location Map shows the location of the study area shaded orange. Figure 1 - Study Location Map Background This report is the third phase of a multi-phased development project. Phase 1 comprised of construction of an access road, parking area, and eight fenced-in multipurpose fields. Phase 2 comprised of installation of a groundwater well and associated infrastructure to support water supply needs. Phase 3 (current) includes a drainage study and flood control design in advance of the construction of the drainage channels and detention basin needed to protect existing and future development of the 427-acre Pahrump Fairgrounds as a major recreation event center. ---PAGE BREAK--- Page 3 9160 Double Diamond ParkwayI Reno, Nevada I 89521 P. (775) 852-1440 F. (775) 852-1441 @ dyerengineering.com Phase 1: The Town of Pahrump obtained U.S. Housing and Urban Development (HUD) Economic Development Incentive (EDI) grants, in conjunction with local funding resources to pay for the construction of Fox Road and its associated parking lot, as well as the fenced soccer fields that currently exist at the fairgrounds. Phase 2: Nye County obtained HUD EDI funding, in conjunction with local resources, to pay for construction of a groundwater well and supporting infrastructure to supply water to the fairgrounds. Phase 3: Nye County is requesting $124,000 to help prepare a drainage study and develop a Flood Control Design Plan in advance of the construction of these infrastructure elements, as these features are critical to protecting the existing and future development of the fairgrounds the town and county have worked so hard to conceptualize and build. Subsequent funding to construct these features will be requested during subsequent funding rounds for the Community Development Block Grant (CDBG). Design Criteria The Guidelines for Design and Review of Development Engineering (Nye County Pahrump Regional Planning District, 2017) outlines the design standards of storm drainage facilities and improvements. The following standards were applied in the analysis for the Pahrump Fairgrounds Facility.  Storm detention facilities shall be designed to provide storage using a 10-year event, with the safe overflow conveyance of the 100-year event.  Calculations of site discharge for both existing and proposed conditions.  Storms to be evaluated shall include: o 10-year event o 25-year event o 100-year event  The post-development discharge rate for the 5, 10 and 25-year events shall be that of the pre-development discharge rate.  Maximum allowable release rate of 0.5 cubic feet per second per acre in the 25-year event. Partial Build-Out The Pahrump Fairgrounds plans to grow and develop over time. The partial build-out condition will get the fairgrounds underway by including the following:  Extension of Fox Road to connect with Wheeler Pass creating an intersection with  Highway NV-160  Rodeo Grounds  Multipurpose Fields (completed)  Parking Lot (completed)  Phased detention basin area ---PAGE BREAK--- Page 4 9160 Double Diamond ParkwayI Reno, Nevada I 89521 P. (775) 852-1440 F. (775) 852-1441 @ dyerengineering.com These features will be analyzed in determining the partial phase of the detention basin sizing. See sheet C1.2 of Appendix A - Schematic Design Plans for the layout of these conditions. Future Build-Out The future build-out condition of the Pahrump Fairgrounds will continue to grow and expand the amenities by including the following in addition to the partial build-out:  Stadium Track  Commercial Properties  Off-Road Park These features will be analyzed in determining the future phase of the detention basin sizing. See sheet C1.3 of Appendix A - Schematic Design Plans for the layout of these conditions. Site Conditions The project site currently has a natural flow pattern from northeast to southwest as it drains from the mountain range. Highway NV-160 runs adjacent to the project site on the upper limits of the parcel. The highway has nine existing culvert crossings that convey water into the fairground limits.

The CN is based on soils, plant cover, amount of impervious areas, interception, and surface storage. Figure 2 - Soil Mapping shows the soil classifications for the study area. Soil classifications have a detailed summary of the soil properties in Appendix C - Calculations. Figure 2 - Soil Mapping (USDA 2019) Hydrology and Hydraulics Analysis HydroCad software was used in modeling and calculating the estimated runoff in order to size the detention basin. This modeling software allows data parameters from the SCS Runoff Curve Number method from the Technical Release 55 (TR-55) report to be implemented in the modeling process (United States Department of Agriculture, 1986). HydroCad modeled the system with a 10-year, 25-year, and 100-year 6-hour storm event per the design recommendations (Nye County Pahrump Regional Planning District, 2017). All calculations, inputs, and results from the HydroCad model are in Appendix C - Calculations. The area was divided up by subbasin limits defined by how water flows throughout the terrain. Sheet C1.1 – C1.3 of Appendix A - Schematic Design Plans demonstrates the subbasins and their corresponding name and location. On the northeast side of NV-160, are “OFF” subbasins that do ---PAGE BREAK--- Page 6 9160 Double Diamond ParkwayI Reno, Nevada I 89521 P. (775) 852-1440 F.

The “ON” subbasins are basins within the project’s property parcel that represent specific land use or drainage subbasin. The Gamebird ditch that runs adjacent to Gamebird Road collects all the runoff from both “ON” and “OFF” subbasins at a common point labeled as “Gamebird Outlet”. Curve Numbers The new developments and structures being implemented to the fairgrounds property, change the parameters for calculating the amount of runoff. The curve numbers for each basin are listed below in Table 2 - Curve Number (CN) illustrating the changes through the updates of the project site. As development occurs, the CN increases to represent the additional runoff that will occur due to the increase in impervious surfaces. CN also change due to increase or decrease in acreage with the soil properties determining the change in absorption.

The unit cost includes materials, delivery and labor. Nye County currently has a stockpile of riprap approximately 3-inch to 4-inch in size that could be applied to this project to line the detention pond as the velocities are low enough to accommodate this riprap. The channel’s velocities are higher requiring the 6-inch riprap resulting in the most expensive item for this project as it will be delivered from Las Vegas. The money saved is represented in the OPC as ‘Match – Nye County 4” Riprap’ and subtracted out from the ‘Grand Total with Match’ final line item. ---PAGE BREAK--- Page 9 9160 Double Diamond ParkwayI Reno, Nevada I 89521 P.

Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

Soil Survey Area: Clark County Area, Nevada Survey Area Data: Version 13, Sep 12, 2018 Soil Survey Area: Nye County, Nevada, Southwest Part Survey Area Data: Version 10, Sep 14, 2018 Your area of interest (AOI) includes more than one soil survey area. These survey areas may have been mapped at different scales, with a different land use in mind, at different times, or at different levels of detail. This may result in map unit symbols, soil properties, and interpretations that do not completely agree across soil survey area boundaries. Soil map units are labeled (as space allows) for map scales 1:50,000 or larger. Date(s) aerial images were photographed: Jul 6, 2016—Sep 1, 2017 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

BEC performed the sites reconnaissance on September 3, 2019, and September 18, 2019. It should be acknowledged details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein. In summary, the following items were noted: • The Pahrump Fairgrounds Development Area is located at 4670 South Highway 160, Pahrump, Nevada 89048. The subject site totals approximately 75.5 acres on the southwestern portion of a larger 427.24-acre parcel. The subject site includes an unpaved portion of the multipurpose field developed during a previous phase of the Pahrump Fairgrounds expansion, undeveloped fields to the western edge of the parcel, and areas in which surface water drainage channels are planned to be constructed. • Based on a review of historical documents, including Nye County Assessor and Recorder records, the property was owned by the Town of Pahrump at the time of this report. • Based on review of topography maps and field observations, the western side of the subject site can be described as generally being flat lying, while the eastern side is mostly comprised of rolling hills and sand dunes. Local topography trends upward toward the northeast toward the Spring Mountains. According to a prior drainage study completed for the parcel, surface water flows from the northeast toward the southwest across the parcel. The following is a summary of findings associated with the ESA performed for the subject site: • The regulatory database report was purchased through Environmental Data Resources, Inc. (EDR) and the review of the report identified the following: o The regulatory database review did not identify the subject site in any of the databases searched o The regulatory database review identified one gravel pit in the US Mines database within its respective search radius from the subject site. EDR reported the site was located on the parcel, however, it was determined to be located across Nevada Highway 160. The operating gravel pit did not have any reported violations indicative of a release that could impact the subject site, and therefore, was not considered to be a REC, CREC, HREC, BER, or VEC for the subject site at the time of this report. • Site reconnaissance revealed evidence of off-road vehicle traffic and de minimis household debris dumping. No evidence of spills or hazardous waste disposal were observed. BEC has performed a Phase I ESA in conformance with the scope and limitations of ASTM Standard E 1527-13 for the subject site located at 4670 South Highway 160 Pahrump, Nevada 89048 on APN 027- 741-01. Any exceptions to, or deletions from, this practice are described in Section 1.3 of this report. This assessment has revealed no evidence of recognized environmental conditions in connection with the subject site. It is the opinion of BEC the identified conditions above do not warrant additional investigation. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 2 1 INTRODUCTION BEC was retained by Nye County and the Town of Pahrump on behalf of the Rural Desert Southwest Brownfields Coalition to perform a Phase I ESA of the Pahrump Fairgrounds Development Area, located on a portion of APN 027-741-01, and hereinafter referenced as the subject site. This Phase I ESA was prepared as part of the Assessment Grant (BF-99T-61801) funded by the United States Environmental Protection Agency (EPA). According to the Nye County Assessor, the subject site comprises a 75.5-acre area on the southwest portion of a larger 427.24-acre parcel. The location of the subject site is shown in the Vicinity Map and the Assessor’s Parcel Map (Attachment 1, Figure 1 and Figure 2, respectively). The subject site is located at 4670 South Nevada Highway 160 Pahrump, Nevada 89048, as depicted in the Area Reconnaissance Map (Attachment 1, Figure The following sections identify the purpose, detailed scope of services, significant assumptions, limitations and exceptions, and user reliance information relevant to the preparation of this Phase I ESA report. 1.1 Purpose The purpose of this Phase I ESA was to identify any Recognized Environmental Conditions (RECs), Controlled Recognized Environmental Conditions (CRECs), Historical Recognized Environmental Conditions (HRECs), and/or Business Environmental Risks (BERs) that may be present due to past or present land use of the subject site and/or properties in the subject site vicinity, defined by ASTM Standard E 1527-13, Standard Practice for Phase I Environmental Site Assessment as follows: Recognized Environmental Condition (REC) means the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: due to release to the environment; under conditions indicative of a release to the environment; or under conditions that pose a material threat of a future release to the environment. De minimis conditions are not recognized environmental conditions. A Controlled Recognized Environmental Condition (CREC) [is defined as] a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority, with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls. An Historical Recognized Environmental Condition (HREC) [is defined as] a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls. A Business Environmental Risk (BER) [is defined as] a risk which can have a material environmental or environmentally-driven impact on the business associated with the current or planned use a parcel of commercial real estate. This Phase I ESA reviewed the potential for Vapor Encroachment Conditions (VECs) that may be present due to past or present land use of the subject site and/or properties in the subject site vicinity. VECs are defined by ASTM Standard E 2600-15, Standard Guide for Vapor Encroachment Screening on Property Involved in Real Estate Transactions, as the presence or likely presence of Chemicals of Concern that may migrate as vapors into the vadose zone (the area between the ground surface and the water table, in which vapors may migrate) of a property as a result of contaminated soil and/or groundwater on or near the property. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 3 During the course of this assessment, specific existing, potential, or suspect conditions were evaluated that may pose an environmental liability with respect to hazardous substances and/or petroleum products for the current owner, future owners, or operators at the subject site (ASTM, 2013). 1.2 Scope of Work The scope of work in performing this Phase I ESA included four main tasks: a regulatory records review, site reconnaissance, personal interviews, and report preparation. BEC reviewed readily available records from Nye County and the regulatory compliance files of the EDR Summary Radius Map™ Report with Geocheck® dated August 28, 2019. BEC performed the site reconnaissance on September 3, 2019, and September 18, 2019, to make site observations of the subject site and nearby properties. BEC conducted a regulatory compliance file review at the Nevada Division of Environmental Protection (NDEP) on September 10, 2019. BEC interviewed both Jimmy Martinez, Town of Pahrump Building and Grounds Manager, and Tim Dahl, Nye County Public Works Manager, as the site owner representatives to obtain additional current or historic site use information. This report comprises the fourth and final task of the Phase I ESA process. 1.3 Limitations and Exceptions The scope of this evaluation did not include: subsurface exploration, soil or water sampling, chemical analysis, or an evaluation of asbestos, biological agents, cultural and historic resources, ecological resources, endangered species, health and safety, indoor air quality (unrelated to releases of hazardous substances or petroleum products into the environment), industrial hygiene, lead, mold, radon, regulatory compliance, or wetlands. Properties surrounding the site were visually inspected from public rights-of- way or fence lines. Our observations were made from readily accessible vantage points. Although a reasonable effort was made to view relevant site features, some features may have been concealed from view. While this report provides an overview of potential environmental concerns, both past and present, the environmental assessment is limited by the availability of information at the time of the assessment. It is possible unreported disposal of waste or illegal activities impairing the environmental status of the property may have occurred but could not be identified by the assessment. The findings and opinions regarding environmental conditions presented in this report are based on a scope of work authorized by Nye County. Note, however, no scope of work, no matter how exhaustive, can identify all contaminants or all conditions above and below ground. 1.4 Significant Assumptions BEC used the services of a computer database firm to provide a listing of sites within the ASTM standard search distance around the site. BEC assumed the information in this report was accurate unless conflicting information was obtained from credible sources or field observations made by BEC’s environmental professional(s) during the site reconnaissance indicated otherwise. Deviations are subsequently noted in this report. 1.5 Special Terms and Conditions The findings, opinions, and conclusions are based on an analysis of the observed site conditions and the referenced literature. It should be understood the conditions of a site can change with time as a result of natural processes or the activities of man at the subject site or within the site vicinity. Additionally, changes to the applicable laws, regulations, codes, and standards of practice may occur due to government action or the broadening of knowledge. The findings of this report may, therefore, be invalidated over time, in part or in whole, by changes over which neither Nye County nor BEC has any control. Neither Nye County nor BEC can warrant or guarantee that not finding indicators of any particular hazardous material means that this particular hazardous material or any other hazardous materials do not exist on the ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 4 site. Additional research, including invasive testing, can reduce the uncertainty, but no techniques now commonly employed can eliminate the uncertainty altogether. The environmental services described in this report have been conducted in general accordance with current regulatory guidelines and the standard of care exercised by environmental consultants performing similar work in the State of Nevada. No other warranty, expressed or implied, is made regarding the professional opinions presented in this report. This document is intended to be used in its entirety. No portion of the document by itself is designed to completely represent any aspect of the project described herein. Nye County or BEC should be contacted if the reader requires any additional information or has questions regarding the content, interpretations presented, or completeness of this document. 1.6 User Reliance This report may be relied upon and is intended exclusively for use by Nye County and their assigns for the purposes stated within a reasonable time from issuance, but in no event later than 180 days from the date of the report. Land or facility use, on- and off-site conditions, regulations, or other factors may change over time, and additional work may be required with the passage of time. Since site activities and regulations beyond our control could change at any time after the completion of this report, our observations, findings, and opinions can be considered valid only as of the date of the site visit. This report should not be relied upon after 180 days from the date of its issuance (ASTM Standard). Any use or reuse of the findings, opinions, and/or conclusions of this report by parties’ other than Nye County is undertaken at said parties’ sole risk. 2 SITE DESCRIPTION This section provides an overview of the subject site, as well as detailed information regarding site location, land use and zoning information, a description of the local and regional hydrogeological characteristics of the subject site, a list of structures and other improvements, and a general description of adjoining properties. Information regarding the current use of the site and adjoining properties was obtained during records research, site reconnaissance, and personal interviews. 2.1 Location and Site Description The subject site is located at 4670 South Highway 160, Pahrump, Nevada 89048, on a 75.5-acre portion of APN 027-741-01. Please refer to the Vicinity Map (Attachment 1, Figure 1) and the Assessor’s Parcel Map (Attachment 1, Figure 2) for the location of the subject site addressed for the purposes of this study. The Area Reconnaissance Map (Attachment 1, Figure 3) depicts observations of adjoining and nearby properties. The Site Reconnaissance Map (Attachment 1, Figure 4) depicts observations within the subject site. The subject site is a largely undeveloped area surrounded by residential neighborhoods, State Route 160, and the Spring Mountain Motor Resort and Country Club. According to the Nye County Assessor’s Office, the Land Use Code for the subject site is “Single Family Residential with Minor Improvements.” Based on information received from the Nye County Assessor’s Office, the parcel includes no improvements. However, a paved parking lot and fenced firework launch site were observed within the parcel during the site visit (Attachment 3 – Local and Regulatory Records). A portion of the subject site is enclosed within the fenced area, as depicted on Figure 3. Electric utilities would be serviced by the Valley Electric Association, and water and sewer services would be provided by the Great Basin Water Company. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 5 2.2 Current Use of Adjoining Properties The current adjoining property uses are summarized in Table 2-1, below. Table 2-1: Subject Site Adjoining Property Overview Direction Description North: Wulfenstein Gravel Pit and Spring Mountain Motor Resort and Country Club across Nevada Highway 160 East: Fireworks launch area and paved parking lot immediately adjacent to the subject site, within the Pahrump Fairgrounds parcel; Spring Mountain Motor Resort and Country Club across Nevada Highway 160 South: Undeveloped land and unimproved roads appearing to be for future residential development across Gamebird Road West: Commercial and residential development, undeveloped land, and unimproved roads for future residential development 2.3 Physical Setting - Topography and Hydrogeology The subject site is located in the Town of Pahrump, Nevada, in the central part of the Great Basin section of the Basin and Range physiographic province. Pahrump is situated in the Pahrump Valley, within the Mojave Desert valley. Pahrump lies between the Nevada-California state line and Las Vegas, Nevada. The Spring Mountains border the Town of Pahrump on the northeast, while the Nopah, Kingston, and Resting Spring Ranges border the Town on the southwest. According to Hydrology of the Valley-Fill and Carbonate-Rock Reservoirs, Pahrump Valley, Nevada-California, a United States Geologic Survey water supply paper published in 1967, there are major alluvial fans extending far into the valley from the southwest side of the Spring Mountains, which are major topographic features of the area. The publication also states, “the large fans have coalesced with smaller fans at the mouths of smaller canyons to form an extensive alluvial apron along the front of the mountain range” (Malmberg, 1967). The dominant soil composition at land surface in the vicinity of the subject site was based on information provided by Environmental Data Resources, Inc. (EDR), as supplied from the U.S. Department of Agriculture’s Soil Conservation Service. The dominant soil component at land surface is Pahrump, fine sandy loam. The hydrogeologic group defined by the US Department of Agriculture (USDA) is Class C, with slow infiltration rates (NRCS, 2019). The Federal Emergency Management Agency (FEMA) Flood Zone Map (Attachment 1, Figure 5) depicts the location of the subject site in Area of Minimal Flood Zone X, and portions of the parcel north of the subject site are depicted as Zone AO with a Base Flood Elevation of one foot. Based on reviews of topography maps and field observations, the topography of the subject site is mostly level on the western side of the project area and has rolling hills and sand dunes on the eastern side. Local topography trends upward toward the northeast toward the Spring Mountains. Topography maps indicate an approximate elevation change of 75 feet (ft) from the highest to the lowest areas on the parcel. According to a prior drainage study completed for the parcel, surface water flows from the northeast toward the southwest across the parcel. A groundwater well was drilled immediately adjacent to the subject site in 2012. This well, Nevada Well #121981, was determined to have a 60-ft depth to groundwater. Using data from nearby well logs, it was determined localized groundwater flows downgradient toward the southeast. Well logs are provided in Attachment 3 – Local and Regulatory Records. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 6 According to the Western Regional Climate Center (WRCC) Pahrump, Nevada Station #265890, the average January minimum temperature is 27.0 degrees Fahrenheit and the average July maximum is 101.6 with annual average of 4.71 inches of precipitation (WRCC, 2019). Additional physical setting documentation is provided in Attachment 4 – EDR Summary Radius Map Report. 3 USER PROVIDED INFORMATION The following section discusses information provided during interviews with persons associated with the subject site and/or its representatives during the course of this study (Attachment 3.1 Reason for Performing a Phase I Town of Pahrump, owner, requested a Phases I ESA to obtain historical information about potential environmental hazards and evaluate the property for future development. 3.2 Owner, Property Manager, and Occupant Information The Town of Pahrump was the owner of the property at the time of this report. The site includes minor improvements, such as fencing, a paved public roadway, and a paved parking area. Jimmy Martinez, Town of Pahrump Building and Grounds Manager, and Tim Dahl, Nye County Public Works Manager, were interviewed as the owner representatives for the subject site. There were no regular occupants of the site at the time of this report. However, during an interview onsite with Mr. Dahl, he stated the fenced area is open to the public two times per year for Town-supervised firework launching. 3.3 Environmental Liens or Activity and Use Limitations Based on information provided during interviews with Mr. Martinez and Mr. Dahl, no environmental liens or activity and use limitation (AULs) are associated with the subject site (Attachment Additionally, no environmental liens or AULs were reported in the EDR Environmental Report dated September 4, 2019 (Attachment However, Mr. Dahl stated the land patent granting the Town of Pahrump the parcel from the BLM contained use limitations such that commercial, for-profit development would not be permitted. Additional land use restrictions were listed within the land patent documentation (Attachment 3) including: • The patentee or its successor in interest shall comply and shall not violate any of the terms or provisions of Title VI of the Civil Rights Act of 1964, and the requirements of the regulations, as modified or amended, of the Secretary of the Interior issued pursuant thereto (43 CFR 17) for the period that the lands conveyed herein are used for the purpose for which the grant was made pursuant to the act cited above, or for another purpose involving the provision of similar services or benefits. • If the above provisions are not met, the Secretary of the Interior may declare the terms of this grant terminated in whole or in part. • The patentee agrees for itself or its successors in interest that a declaration of termination in whole or in part of this grant shall at the option of the Secretary or his delegate, operate to revest in the United States full title to the lands involved in the declaration. • The United States shall have the right to seek judicial enforcement of the requirements of Title VI of the Civil Rights Act of 1964, and the terms and conditions of the regulations, as modified or amended, of the Secretary of the Interior issued pursuant to said Title VI, in the event of their violation by the patentee. • The patentee or its successor in interest will, upon request of the Secretary of the Interior or his delegate, post and maintain on the property conveyed by this document, signs and posting bearing ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 7 a legend concerning the applicability of Title VI of the Civil Rights Act of 1964 to the area or facility conveyed. 3.4 Specialized Knowledge When queried regarding specialized knowledge concerning the environmental status and potential issues of concern, Mr. Dahl stated he did not have any specialized knowledge or experience related to the property or nearby properties. 3.5 Commonly Known or Reasonably Ascertainable Information When queried regarding commonly known or reasonably ascertainable information concerning the environmental status and potential issues of concern, Mr. Dahl stated the property had been vacant land prior to the improvements done in 2012 to construct multipurpose fields. He did not know of specific chemicals that are present or were once present on the property. He did not know of any spills, chemical releases, or environmental cleanups that have taken place there. 3.6 Valuation Reduction for Environmental Issues When queried regarding valuation reduction for environmental issues, Mr. Dahl stated this was not applicable as the property is already owned by the Town of Pahrump. 4 RECORDS REVIEW The following sections include results and discussion of the search of local, state, and federal standard record sources. 4.1 Title Records Readily available title records retrieved online from the Nye County Recorder’s Office on August 27, 2019, confirmed Town of Pahrump as the current owner of the subject site (Attachment The readily accessible history of ownership information is presented in Table 4-1. Table 4-1: Ownership History Lot Information Document Date Description Document Type APN 027-741-01 9/14/99 Land patent deed received from the United States of America, vested in the Town of Pahrump Land Patent Deed 4.2 Environmental Database Search A search of available federal and state environmental records was obtained from EDR. A copy of the documents provided by EDR can be found in the below referenced attachments: • Attachment 3 – Local and Regulatory Records • Attachment 4 – EDR Summary Radius Map Report • Attachment 5 – Historical Map Reports and Imagery Data The regulatory database search contained within the EDR Radius Map Report (Attachment 4) was reviewed to assess possible RECs within the ASTM approximate minimum search distances. Some records reviewed pertain not only to the property, but also to properties within an additional approximate ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 8 minimum search distance in order to help assess the likelihood of migrating hazardous substances or petroleum products. Although numerous databases were searched during the preparation of this report, those required under ASTM Standard E 1527-13 and ASTM Standard E 2600-15 (ASTM, 2015) have been selected for discussion. The required databases, database update information, and search distances, as well as the number of sites identified within the associated search radii are summarized in Table 4-2 and Table 4-3.

Neither the subject site nor facilities/properties within a 1-mile radius of the subject site were listed. United States EPA, Delisted NPL The EPA Delisted NPL database is a subset of the NPL. Neither the subject site nor facilities within a 1-mile radius of the site were listed. United States EPA, SEMS (formerly the CERCLIS List) The SEMS (formerly CERCLIS) list is an EPA list of sites that are either proposed for or are on the NPL and sites that are in the screening and assessment phase for possible inclusion on the NPL. CERCLIS was renamed to SEMS by the EPA in 2015. Facilities identified by the EPA, which may have the potential for releasing hazardous substances into the environment are provided in the SEMS facilities list. Neither the subject site nor facilities within a 0.5-mile radius of the site were listed. United States EPA SEMS- Archive (formerly CERCLIS-NFRAP) The SEMS-Archive tracks sites that have no further Federal Superfund Program remedial actions based on available information. CERCLIS-NFRAP was renamed SEMS-Archive by the EPA in 2015. The SEMS-Archive list is an EPA database of former SEMS sites where no further remedial action is planned under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). SEMS- ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 10 Archive sites may be sites where, following an initial investigation, no contamination was found, contamination was removed quickly without the need for the site to be placed on the NPL, or the contamination was not serious enough to require Federal Superfund action or NPL consideration. Neither the subject site nor facilities within a 0.5-mile radius of the site were listed. United States EPA, RCRA, CORRACTS List This list is a database of facilities subject to corrective action under RCRA. The list generally identifies EPA-listed facilities that have reported a release of hazardous waste or constituents into the environment and are undergoing corrective action. Corrective action may be required beyond the facility’s boundary and can be required regardless of when the release occurred. Neither the subject site nor facilities within a 1-mile radius of the site were listed. United States EPA, RCRA non-CORRACTS, TSD Facilities List This database identifies EPA-listed facilities which report storage, treatment, and/or disposal of hazardous waste under the EPA’s RCRA program.

United States EPA, RCRA Non-Generators List This database identifies EPA-listed facilities which may store or transport hazardous waste or meet other RCRA requirements but do not generate hazardous waste. Neither the subject site nor facilities within a 0.125-mile radius of the site were listed. United States EPA, RCRA Generators List This database identifies EPA-listed facilities which generate or transport hazardous waste or meet other RCRA requirements. The types of facilities within this database include: Large Quantity Generators, Small Quantity Generators, and Conditionally Exempt Generators. Neither the subject site nor facilities within a 0.125-mile radius of the site were listed. Federal Institutional Control/Engineering Control Registries These registries comprise information obtained from two main sources. The first source, the Brownfield Management System, is a database designed to assist the EPA in collecting, tracking, and updating information relevant to federal, state, and local Brownfield programs. The Small Business Liability Relief and Brownfields Revitalization Act (“Brownfields Law,” Public Law 107-118) defines a brownfield site as “real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant,” as defined in CERCLA. The second source is a database of Superfund sites that have either an engineering or institutional control. Neither the subject site nor facilities within a 0.5-mile radius of the site were listed. Federal ERNS List This list comprises a database of emergency response actions and may include reported CERCLA hazardous substance releases or spills in quantities greater than the reportable quantity, as maintained at the National Response Center. Data since January 2001 has been received from the National Response System database as EPA no longer maintains this data. The subject site was not listed. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 11 State/Tribal Equivalent NPL: NDEP, Superfund Branch The EPA NPL database comprises confirmed or proposed hazardous waste sites targeted for possible long-term remedial action under the Superfund Program. In Nevada, state equivalent NPL Facilities and/or sites are designed and overseen by NDEP, Bureau of Corrective Actions, Superfund Branch. Neither the subject site nor facilities within a 1-mile radius of the site were listed. State/Tribal Equivalent SEMS (formerly CERCLIS): NDEP Bureau of Corrective Actions, SHWS List The NDEP Bureau of Correction Actions maintains a list and oversees cleanup of releases of regulated substances. Neither the subject site nor facilities within a 1-mile radius of the site were listed. State/Tribal LUST: NDEP, Bureau of Corrective Actions, LUST List The LUST Information System is maintained by NDEP, Bureau of Corrective Actions. The Bureau maintains an inventory of sites with leaking underground storage tanks, including sites with tanks under investigation for potential leaks, confirmed leaks, and those to be closed. Neither the subject site nor facilities within a 0.5-mile radius of the site were listed. State/Tribal UST/AST: NDEP, Bureau of Corrective Actions, UST/AST Registration This list identifies facilities containing registered USTs and/or ASTs. Neither the subject site nor facilities within a 0.125-mile radius of the site were listed. State/Tribal Institutional Controls/Engineering Controls/Voluntary Cleanup Sites Institutional controls (administrative and legal controls) and engineering controls (physical barriers or processes) are designed to minimize the potential for human exposure to contaminants. NDEP provides oversight for the Nevada Voluntary Cleanup Program, which provides relief from liability to owners who undertake cleanups of contaminated properties. Neither the subject site nor facilities within a 0.5-mile radius of the site were listed. State/Tribal Brownfield Sites NDEP Bureau of Corrective Actions maintains a list of Brownfield sites as part of its listing of clean-up evaluations and actions regarding sites with actual or potential contamination. Neither the subject site nor facilities within a 0.5-mile radius of the site were listed. State/Tribal Solid Waste Landfill (SWL): NDEP, Bureau of Waste Management, Landfill List NDEP Bureau of Waste Management, Solid Waste Management Branch, maintains lists of facilities including active solid waste disposal sites, inactive or closed solid waste disposal sites, and transfer facilities. The EDR Report identified no solid waste facilities within the 0.5-mile search radius. State/Tribal Open Dump Inventory An open dump is defined as a disposal facility that does not comply with one or more of the 40 Code of Federal Regulations (CFR) Part 257 or Part 258 Subtitle D Criteria, which establish revised minimum federal criteria that include location restrictions, facility design and operating criteria, groundwater and ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 12 landfill gas monitoring requirements, corrective action requirements, financial assurance requirements, and closure and post-closure care requirements. The EDR Report identified no open dump inventory listings within the 0.5-mile search radius. US Mines Index File The Mines Master Index File contains all mine identification numbers issued for mines active or opened since 1971. The data also includes violation information. Although this is not a required database search under the ASTM standard, EDR provides information from this database if nearby sites are located. The report identified one gravel pit listed in the US Mines database within a 0.25-mi radius of the subject site. Wulfenstein Construction, Mine ID 2601506, was located 0.237 miles northeast of the subject site, within the parcel boundary, but outside the subject site. Upon further investigation, however, the Wulfenstein Gravel Pit was determined to be incorrectly plotted by EDR as it is located north of the parcel, across Highway 160. According to the Mine Safety and Health Administration, this was an active surface mining operation producing construction sand and gravel as of November 12, 2014. Due to the surface mining operations being greater than 0.25 miles from the subject site, a highway acting as a barrier between the mine and the subject site, mining activities limited to gravel pit operations, and not having any reported violations indicative of a release that could impact the subject site, this site was not considered a REC, CREC, HREC, BER, or VEC for the subject site at the time of this report. Orphan Sites Due to discrepancies in the location of some facilities in the databases arising from incomplete or incorrect addresses, some facilities were listed as un-mappable, otherwise known as “orphan sites”. The report identified 25 orphan sites. BEC determined none of these sites were located within 1-mile of the subject site, and therefore, were not considered a REC, CREC, HREC, BER, or VEC for the subject site at the time of this report. 4.3 Local Records Documentation Information regarding the subject site was obtained from the offices of the Nye County Assessor, the Nye County Recorder, and NDEP (Attachment A historical EDR City Directory Image Report was prepared for this site. Refer to the EDR City Directory Image Report for specific details (Attachment In the late nineteenth century, companies, such as the Sanborn Company, began preparing maps of central business districts for use by fire insurance companies. These maps were updated periodically throughout the twentieth century. Fire insurance maps often indicate construction materials, specific property use, and the location of other features such as gasoline storage tanks. Please refer to the Certified Sanborn Map for specific details regarding the coverage for the subject site (Attachment Information from these City Directories and Certified Sanborn Maps was used to develop the site history (further discussed in Section 4.4). The University of Nevada Radon Education Program compiles short-term radon test results that were completed by Nevada homeowners from 1989 to 2015. The results were compiled for each county by zip code and a corresponding geographical information systems (GIS) map based on zip codes was designed by the University of Nevada Cooperative Extension and the Nevada Bureau of Mines and Geology. The MyHazards interactive webmap was reviewed and the Radon Potential in the vicinity of the subject site was noted as 8.22 % (UNR, 2015) (Attachment ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 13 4.4 Historical Use Information on Property and Adjoining Properties This section describes the historical land use of the subject site and adjoining properties compiled from several resources, including the EDR City Directory Image Report (Attachment 3) and the Historical Topo Map Report and Satellite Imagery Data (Attachment The objective of consulting historical sources is to develop the history of the previous uses of the surrounding properties in order to help identify the likelihood of past uses having led to recognized environmental conditions in connection with the property. The historical uses of the subject site and properties in the immediate vicinity of the subject site are summarized below in Table 4-8. These uses were determined using public records available through Nye County, EDR City Directory Image Report, aerial photography review, and observations made during the site visit. Line items in bold were identified as a REC, HREC, or CREC for the subject site at the time of this report.

BEC performed the site reconnaissance on September 3, 2019 and September 18, 2019. BEC conducted site observations on the western side of the project area and the easternmost proposed drainage channel area beginning at approximately 7:10 am on September 3, 2019. The temperature was approximately 72 °F with calm winds. Rachel Schlick (Environmental Scientist IV) and Rachel Kistler (Environmental Scientist I) of BEC were present for the first day of site reconnaissance. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 15 BEC conducted site observations on the eastern side of the project area beginning at approximately 8:15 am on September 18, 2019. The temperature was approximately 63 °F with calm winds. Rachel Kistler (Environmental Scientist I) and Danielle Viglione (Environmental Scientist I) were present for the second day of site reconnaissance. BEC performed a visual survey of the adjoining properties to the north, east, south, and west of the subject site in order to evaluate the types of businesses, structures and any conditions of the neighboring properties that may pose an environmental risk to the subject site. Structures of particular note (i.e. exposed pipes, above ground storage tanks, etc.) were photographed and observations recorded in a field log. Conditions of the subject site and adjoining properties were visually evaluated for potential RECs. Photos taken during the site reconnaissance are provided in Attachment 6 – Site Reconnaissance Documentation. 5.1 General Site Setting The subject site is comprised of a 75.5-acre area on the southwestern portion of a larger 427.24-acre parcel located at 4670 South Highway 160, Pahrump, Nevada 89048. Features of adjoining and nearby properties are identified in the Area Reconnaissance Map (Attachment 1, Figure Key observations made during the exterior portion of the site visit are depicted in the Site Reconnaissance Map (Attachment 1, Figure The current use of adjoining properties to the north, east, south, and west are described in Table 2-1. 5.2 Exterior Observations BEC walked the perimeter of the subject site and noted conditions inconsistent with those expected for a Single Family Residential neighborhood. The initial observations were conducted beginning within the eastern fenced area north of the paved parking lot. There was a desert tortoise fence surrounding the chain-link fence and large streetlights (Attachment 6, Photo This area had been graded to be used as an additional parking area. Tire tracks and de minimis debris were observed in this location (Attachment 6, Photo A fire department water truck, a Conex storage container, and a plastic trash bin were observed near the paved parking area (Attachment 6, Photo A darker area of soil was observed between the truck and the Conex storage container box, consistent in appearance, odor, and texture of water (Attachment 6, Photo No odors or additional staining were observed within this patch of soil. The drainage ditch north of the fenced area was then observed (Attachment 6, Photo This area had been trenched out and lined with riprap material. De minimis amounts of non-commercial fireworks waste were observed in this area. No hazardous materials, staining, pipes, or structures were observed. The western half of the subject site was observed on foot. This side was very flat with desert salt scrub plant life (Attachment 6, Photo There were dirt roads throughout, likely used by off-road vehicles (Attachment 6, Photo De minimis household debris (paper, glass, clothing, etc.) was observed in few locations along the dirt roadways (Attachment 6, Photos 8-9). One small pile of construction debris appeared to have possibly been burned and dumped (Attachment 6, Photo 10). Various empty containers (plastic buckets, aluminum cans, glass bottles, plastic bottles) were scattered throughout the area (Attachment 6, Photo 11). All containers observed no longer had labels or material inside. No hazardous materials, staining, pipes, or structures were observed on the western half of the subject site. During the second site visit, the eastern half of the subject site was observed both on foot and in the field vehicle. This area had areas of flat terrain in addition to areas of rolling sand dunes (Attachment 6, Photo 12). Some dunes appeared to be piles of sand/soil from prior excavation of drainage trench and leveling of parking area, while other dunes appeared to be a part of the natural alluvial fan topography. Similar to the ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 16 western half, the eastern half had dirt roads throughout, however, they appeared to be much less traveled than the western side. No hazardous materials, staining, pipes, or structures were observed on the eastern half of the subject site. 6 INTERVIEWS The Phase I ESA is done to identify recognized environmental conditions that may be present due to past or present land use of the subject site, and/or properties in the site vicinity. BEC conducted interviews as discussed in Section 6.1 and Section 6.2 below. Interview documentation is provided in Attachment 2. 6.1 Interview with Owner Representative Jimmy Martinez, Town of Pahrump Building and Grounds Manager, and Tim Dahl, Nye County Public Works Manager, both provided interviews as site owner representatives. Both stated to the best of their knowledge, the subject site had been vacant land. Neither knew of specific chemicals that are present or were once present on the property. Neither knew of any spills, chemical releases, or environmental cleanups that had taken place at the property. Mr. Martinez was not aware of any environmental liens or activity and use limitation (AULs) associated with the subject site. As discussed in Section 3.3 of this report, Mr. Dahl stated he was aware of land use limitations for the parcel which were issued as part of the land patent. 6.2 Other Interviews During the first site visit, Mr. Dahl, was interviewed at the subject site. He mentioned the fenced area is open to the public two times per year for Town-supervised firework launching. He mentioned that an Environmental Assessment had been conducted for the portion of the parcel that had been fenced and paved, and there were no findings related to that assessment. 7 FINDINGS, OPINIONS, AND CONCLUSIONS The following is a summary of findings associated with the Phase I ESA performed for the subject site: • The regulatory database report was purchased through EDR and the review of the report identified the following: o The regulatory database review did not identify the subject site in any of the databases searched. o The regulatory database review identified one gravel pit listed in the US Mines database within its respective search radius from the subject site. EDR reported the site was located on the parcel, however, it was determined to be located across Nevada Highway 160. The operating gravel pit did not have any reported violations indicative of a release that could impact the subject site, and therefore, was not considered to be a REC, CREC, HREC, BER, or VEC for the subject site at the time of this report. • Site reconnaissance revealed evidence of off-road vehicle traffic and de minimis household debris dumping. No evidence of spills or hazardous waste disposal were observed. ---PAGE BREAK--- SIGN SIGN SIGN ---PAGE BREAK--- Pahrump Fairgrounds Development Area Phase I ESA APN 027-741-01 October 7, 2019 18 9 REFERENCES ASTM.

Generated via a search of municipal building permit records gathered from more than 1,600 cities nationwide, this report will assist you in meeting the search requirements of EPA’s Standards and Practices for All Appropriate Inquiries (40 CFR Part 312), the ASTM Standard Practice for Environmental Site Assessments (E 1527-13), or custom requirements developed for the evaluation of environmental risk associated with a parcel of real estate. Building permit data can be used to identify current and/or former operations and structures/features of environmental concern. The data can provide information on a target property and adjoining properties such as the presence of underground storage tanks, pump islands, sumps, drywells, etc., as well as information regarding water, sewer, natural gas, electrical connection dates, and current/former septic tanks. ASTM and EPA Requirements ASTM E 1527-13 lists building department records as a "standard historical source," as detailed in § 8.3.4.7: “Building Department Records - The term building department records means those records of the local government in which the property is located indicating permission of the local government to construct, alter, or demolish improvements on the property.” ASTM also states that “Uses in the area surrounding the property shall be identified in the report, but this task is required only to the extent that this information is revealed in the course of researching the property itself.” EPA’s Standards and Practices for All Appropriate Inquires (AAI) states: "§312.24: Reviews of historical sources of information. Historical documents and records must be reviewed for the purposes of achieving the objectives and performance factors of §312.20(e) and Historical documents and records may include, but are not limited to, aerial photographs, fire insurance maps, building department records, chain of title documents, and land use records.” Methodology EDR has developed the EDR Building Permit Report through our partnership with BuildFax, the nation’s largest repository of building department records. BuildFax collects, updates, and manages building department records from local municipal governments. The database now includes 30 million permits, on more than 10 million properties across 1,600 cities in the United States. The EDR Building Permit Report comprises local municipal building permit records, gathered directly from local jurisdictions, including both target property and adjoining properties. Years of coverage vary by municipality. Data reported includes (where available): date of permit, permit type, permit number, status, valuation, contractor company, contractor name, and description. Incoming permit data is checked at seven stages in a regimented quality control process, from initial data source interview, to data preparation, through final auditing. To ensure the building department is accurate, each of the seven quality control stages contains, on average, 15 additional quality checks, resulting in a process of approximately 105 quality control “touch points.” For more information about the EDR Building Permit Report, please contact your EDR Account Executive at (800) 352-0050. ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- Pahrump Fairgrounds Drainage Basin 4670 S Highway 160 Pahrump, NV 89048 Inquiry Number: 5768571.5 August 28, 2019 The EDR-City Directory Image Report 6 Road Shelton, CT 06484 [PHONE REDACTED] www.edrnet.com Environmental Data Resources Inc Environmental Data Resources Inc Environmental Data Resources Inc Environmental Data Resources Inc ---PAGE BREAK--- TABLE OF CONTENTS SECTION Executive Summary Findings City Directory Images Thank you for your business.

SURROUNDING SITES: SEARCH RESULTS Surrounding sites were identified in the following databases. Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property. Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed. Sites listed in bold italics are in multiple databases. Unmappable (orphan) sites are not considered in the foregoing analysis. US MINES: A review of the US MINES list, as provided by EDR, has revealed that there is 1 US MINES site within approximately 0.25 miles of the target property.

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. ---PAGE BREAK--- 06/15/2020 Event Code: 08ENVS00-2020-E-00251 2 ▪ ▪ ▪ ▪ A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/ comtow.html.

Migratory Birds Certain birds are protected under the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act . Any person or organization who plans or conducts activities that may result in impacts to migratory birds, eagles, and their habitats should follow appropriate regulations and consider implementing appropriate conservation measures, as described below. The Migratory Birds Treaty Act of 1918. The Bald and Golden Eagle Protection Act of 1940. 50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a) The birds listed below are birds of particular concern either because they occur on the USFWS Birds of Conservation Concern (BCC) list or warrant special attention in your project location. To learn more about the levels of concern for birds on your list and how this list is generated, see the FAQ below. This is not a list of every bird you may find in this location, nor a guarantee that every bird on this list will be found in your project area. To see exact locations of where birders and the general public have sighted birds in and around your project area, visit the E-bird data mapping tool (Tip: enter your location, desired date range and a species on your list). For projects that occur off the Atlantic Coast, additional maps and models detailing the relative occurrence and abundance of bird species on your list are available.

Breeds elsewhere Rufous Hummingbird selasphorus rufus This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. Breeds elsewhere Probability Of Presence Summary The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ “Proper Interpretation and Use of Your Migratory Bird Report” before using or attempting to interpret this report. Probability of Presence ( ) Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated? The calculation is done in three steps: The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. ---PAGE BREAK--- 06/15/2020 Event Code: 08ENVS00-2020-E-00251 3 3. ▪ no data survey effort breeding season probability of presence The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. Breeding Season ( ) Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort ( ) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. No Data ( ) A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures and/or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location. The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets . Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and ---PAGE BREAK--- 06/15/2020 Event Code: 08ENVS00-2020-E-00251 5 1. 2. 3. how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. ---PAGE BREAK--- 06/15/2020 Event Code: 08ENVS00-2020-E-00251 6 What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern.

Please be aware this report provides the “probability of presence” of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the “no data” indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ “Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds” at the bottom of your migratory bird trust resources page. ---PAGE BREAK--- 06/15/2020 Event Code: 08ENVS00-2020-E-00251 1 ▪ Wetlands Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

Breeds Dec 1 to Aug 31 Long-billed Curlew Numenius americanus This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. Breeds elsewhere Rufous Hummingbird selasphorus rufus This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. Breeds elsewhere Probability Of Presence Summary The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ “Proper Interpretation and Use of Your Migratory Bird Report” before using or attempting to interpret this report. Probability of Presence ( ) Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated? The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. ---PAGE BREAK--- 09/03/2019 Event Code: 08ENVS00-2019-E-00287 3 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. Breeding Season ( ) Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort ( ) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. No Data ( ) A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures and/or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location. The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets . Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? ---PAGE BREAK--- 09/03/2019 Event Code: 08ENVS00-2019-E-00287 5 To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur.

In order to fulfill your request an analysis was performed using the best available data from the NDOW’s wildlife occurrences, raptor nest sites and ranges, greater sage- grouse leks and habitat, and big game distributions databases. No warranty is made by the NDOW as to the accuracy, reliability, or completeness of the data for individual use or aggregate use with other data. These data should be considered sensitive and may contain information regarding the location of sensitive wildlife species or resources. All appropriate measures should be taken to ensure that the use of this data is strictly limited to serve the needs of the project described on your GIS Data Request Form. Abuse of this information has the potential to adversely affect the existing ecological status of Nevada’s wildlife resources and could be cause for the denial of future data requests. To adequately provide wildlife resource information in the vicinity of the proposed project the NDOW delineated an area of interest that included a four-mile buffer around the project area provided by you on Tuesday, August 27, 2019. Wildlife resource data was queried from the NDOW databases based on this area of interest. The results of this analysis are summarized below. Big Game - Occupied elk distribution exists outside of the project area within portions of the four-mile buffer area. No known occupied bighorn sheep, mule deer, or pronghorn antelope distributions exist in the vicinity of the project area. Please refer to the attached maps for details regarding big game distributions relative to the proposed project area. Greater Sage-Grouse - There is no known greater sage-grouse habitat in the vicinity of the project area. Raptors - Various species of raptors, which use diverse habitat types, may reside in the vicinity of the project area. American kestrel, bald eagle, barn owl, burrowing owl, Cooper's hawk, ferruginous hawk, flammulated owl, golden eagle, great horned owl, long-eared owl, merlin, northern goshawk, northern harrier, northern saw-whet owl, osprey, peregrine falcon, red-tailed hawk, rough-legged hawk, sharp- shinned hawk, short-eared owl, Swainson's hawk, and turkey vulture have distribution ranges that include the project area and four-mile buffer area. Furthermore, bald eagle, burrowing owl, golden eagle, merlin, prairie falcon, and rough-legged hawk have been directly observed in the vicinity of the project area. Raptor species are protected by State and Federal laws. In addition, bald eagle, burrowing owl, California spotted owl, ferruginous hawk, flammulated owl, golden eagle, northern goshawk, peregrine falcon, prairie falcon, and short-eared owl are NDOW species of special concern and are target species for conservation as outlined by the Nevada Wildlife Action Plan.

(BEC) was retained by the Town of Pahrump to perform a Biological Evaluation (BE) of the Pahrump Fairgrounds Development Area, located at 4670 South Highway 160, Pahrump, Nevada 89048, within a portion of Nye County Assessor’s Parcel Number (APN) 027-741-01 (Figure 1-1). The Town of Pahrump acquired the patent on this parcel in 1999 from the Bureau of Land Management and designated the entire parcel as the Pahrump Fairgrounds with the goal of developing the area to provide varied recreation and community support programs. To that end, the Town developed a portion of the parcel in 2012, including construction of the access road Fox Avenue, a parking area, a fenced multipurpose field, a groundwater well, and infrastructure to support water needs (Appendix A – Photo Log: Photos 1-4). The current project includes development of a detention basin, the extension of a drainage channel to the basin, a parking lot, and a community development building within the previously constructed multipurpose field area. The project is being funded, in part, by the United States Department of Housing and Urban Development (HUD). Figure 1-1: Project Location Map. 1.2 Purpose of this Document This BE has two objectives. First, the document assesses potential effects of the construction of a stormwater detention basin and associated drainage channels, a paved parking area, and a small building ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 2 on the biological resources within and adjacent to the Project Site. This document will support the overall assessment of potential impacts of the project on the human environment in accordance with the National Environmental Policy Act (NEPA) and associated regulations, and HUD guidelines. In addition to and in furtherance of the first objective, this document will evaluate the potential for the project to affect species listed as endangered or threatened under the Endangered Species Act (ESA), or their designated critical habitat. As this project is funded in part by a federal agency, Section 7 of the ESA assures, through consultation or conferencing with the United States Fish and Wildlife Service (USFWS), federal actions do not jeopardize the continued existence of any threatened, endangered, or listing- proposed species, or result in the destruction or adverse modification of designated critical habitat. 2 PROJECT DESCRIPTION 2.1 Action Area For the purpose of this BE, the Action Area addresses all areas to be affected directly or indirectly by the action including all maintenance areas, staging areas, and access road. The Action Area for this project will be defined as the southwestern 120 acres of the 427-acre parcel, as seen in Figure 2-1. This area includes the Project Site in which proposed facilities will be constructed, as well as the existing access road (Fox Road) from Gamebird Road, parking area, and multi-purpose field where a building will be constructed. The existing stockpile of excess soil will be used as fill material where necessary. The existing paved parking area and multi-purpose field also will be used as a staging area for construction activities, such as a construction yard, lay-down area for materials, and the stockpile storage of excavated soils. 2.2 Project Description The current proposed action is intended to provide additional flood-flow protection with the development of additional stormwater drainage channels and a detention basin, and the construction of additional amenities for recreational and community activities. The following sections provide additional detail on the project components. Figure 2-2 provides a diagram of these facilities which are further described below. 2.2.1 Flood Facilities The project includes the extension of the existing stormwater drainage channel on the site to direct surface water flow into a detention basin to be constructed onsite (Figure 2-2). The existing drainage channel is approximately 610 feet long and 15 to 23 feet wide with a depth of approximately 3 feet. The existing channel does not extend the entire length of the existing multi-purpose fields therefore this project will include an extension of the rip-rap channel approximately 480 feet east to protect that portion of the existing development. The rip-rap channel will be extended 3,230 feet west of existing drainage channel to connect with the proposed detention basin. The detention basin will be constructed in the western portion of the Project Site and will be 250 feet wide, 350 feet long, and 3 feet deep. The basin will be constructed with a 3:1 side slope and lined with four-inch riprap, providing a total capacity of 6.4 acre-feet. Excess soils generated from the construction of these facilities will be distributed across the remainder of the property as fill material as needed. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 3 Figure 2-1: Action Area and Existing Facilities. 2.2.2 Expanded Parking A 2.6-acre paved parking lot will be constructed on the western side of Fox Avenue mirroring the existing lot. Soils graded for this construction will be relocated within the Action Area. 2.2.3 Community Development Center A 15,000-square-foot, single-level community development center will be constructed in the center of the Project Site, north of the Fox Avenue parking lots. The community development center will provide the Pahrump community a space for extracurricular activities. 2.2.4 Lay-down and Construction Yards The existing multi-purpose field and parking area will be used as the construction yard. This area will be used for parking of equipment, storage of construction materials, and temporary storage of excess soils from the construction activities. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 4 Figure 2-2: Map of Proposed Project Components. 3 PROJECT SITE DESCRIPTION BEC biologists reviewed readily available information from state and federal agencies to develop a description of the physical and natural environment within and around the area. The following description is based on a review of this information. 3.1 Soils The Project Site is located along the edge of an alluvial fan, or bajada, and the remnant terraces of a dry lake. The soils found within the subject site, being lower on the alluvial fan, tend to represent the lacustrine influence while the remainder of the parcel represents the alluvial deposits from the surrounding mountains. The following map units were identified from Natural Resources Conservation Service (NRCS) soil survey maps and the descriptions are adapted from the soil survey information (NRCS, 2017). A map of the soil units and detailed description of the soils are provided in Appendix B – Soil Survey. The majority of the Project Site is within Map Unit 2110, while the southwest corner of the area is within Map Unit 3320. Both map units have saline and sodic horizons within 30 inches of the surface. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 5 Map Unit: 2110 – Pahrump fine sandy loam, 4 to 15 percent slopes This unit occurs on lake terraces along the edges of bolsons or dry lakes.

The soil has a sodic horizon within 30 inches of the soil surface. 3.2 Vegetation Land Cover Description U.S. Geological Survey (USGS) National Southwest Regional Gap Analysis Program (SWReGAP) vegetation community data was used to determine expected vegetation communities on the Project Site ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 6 (USGS, 2018). According to the Ecological System output, three vegetation communities are present within the Project Site: Sonora-Mojave Creosotebush-White Bursage Desert Scrub, Sonora-Mojave Mixed Salt Desert Scrub, and North American Warm Desert Playa. The northern portion of subject parcel is identified as Sonora-Mojave Creosotebush-White Bursage Desert Scrub and is described below. “This ecological system forms the vegetation matrix in broad valleys, lower bajadas, plains and low hills in the Mojave and lower Sonoran deserts. This desert scrub is characterized by a sparse to moderately dense layer (2-50% cover) of xeromorphic and broad-leaved shrubs. Larrea tridentata and Ambrosia dumosa are typically dominants, but many different shrubs, dwarf-shrubs, and cacti may codominate or form typically sparse understories. Associated species may include Atriplex canescens, Atriplex hymenelytra, Encelia farinosa, Ephedra nevadensis, Fouquieria splendens, Lycium andersonii, and Opuntia basilaris. The herbaceous layer is typically sparse, but may be seasonally abundant with ephemerals. Herbaceous species such as Chamaesyce spp., Eriogonum inflatum, Dasyochloa pulchella, Aristida spp., spp., Nama spp., and Phacelia spp. are common.” The southern portion of subject parcel is identified as Sonora-Mojave Mixed Salt Desert Scrub and is described below. “This system includes extensive open-canopied shrublands of typically saline basins in the Mojave and Sonoran deserts. Stands often occur around playas. Substrates are generally fine-textured, saline soils. Vegetation is typically composed of one or more Atriplex species such as Atriplex canescens or Atriplex polycarpa along with other species of Atriplex. Species of Allenrolfea, Salicornia, Suaeda, or other halophytic plants are often present to codominant. Graminoid species may include Sporobolus airoides or Distichlis spicata at varying densities.” The southwestern corner of the subject parcel, location of detention basin, is described as North American Warm Desert Playa and is described below. “This system is composed of barren and sparsely vegetated playas (generally <10% plant cover) found across the warm deserts of North America, extending into the extreme southern end of the San Joaquin Valley in California. Playas form with intermittent flooding, followed by evaporation, leaving behind a saline residue. Salt crusts are common throughout, with small saltgrass beds in depressions and sparse shrubs around the margins. Subsoils often include an impermeable layer of clay or caliche. Large desert playas tend to be defined by vegetation rings formed in response to salinity. Given their common location in wind-swept desert basins, dune fields often form downwind of large playas. In turn, playas associated with dunes often have a deeper water supply. Species may include Allenrolfea occidentalis, Suaeda spp., Distichlis spicata, Eleocharis palustris, Oryzopsis spp., Sporobolus spp., Tiquilia spp., or Atriplex spp. Ephemeral herbaceous species may have high cover periodically.” 4 AGENCIES QUERIED 4.1 USFWS BEC performed a data request using with the USFWS Information for Planning and Consultation (IPaC) system on September 3, 2019, to obtain a list of threatened and endangered species that may occur in the proposed Project Site or that may be affected by the proposed action. The species list provided by USFWS fulfilled the requirement under Section 7(c) of the 1973 ESA, as amended (ESA, 16 U.S.C. 1531 ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 7 et seq.). Results of the USFWS search identified three species listed as threatened or endangered under the ESA known to occur in the region. Two of the listed species, the southwestern willow flycatcher (Empidonax traillii extimus) and the Yuma clapper rail (Rallus longirostris yumanensis), were listed as endangered while the other, the Mojave desert tortoise (Gopherus agassizii), was listed as threatened. The USFWS reported no critical habitat within the Project Site for any species (Appendix C: Agency Coordination and Correspondence). As part of the material received from the USFWS IPaC for the ESA-listed species, the USFWS also stated under the Migratory Bird Treaty Act of 1918 (16 USC Sections 703-712), federally listed (50 CFR Section 10) migratory bird species, their nests, and their eggs are protected. A migratory bird is any species or family of birds that live, reproduce, or migrate within or across international borders at some point during its annual life cycle. As with migratory birds, the USFWS reaffirmed under the Bald and Golden Eagle Protection Act of 1940 (16 USC Sections 668-668c), federally listed (50 CFR Section 22), and amended several times since, prohibits anyone, without a permit issued by the Secretary of the Interior, from "taking" bald or golden eagles, including their parts, nests, or eggs. The Act provides criminal penalties for persons who "take, possess, sell, purchase, barter, offer to sell, purchase or barter, transport, export or import, at any time or any manner, any bald eagle [or any golden eagle], alive or dead, or any parts, nest, or egg thereof." 4.2 Nevada Department of Wildlife In support of this BE, BEC requested data on species potentially affected by the project from the Nevada Department of Wildlife (NDOW) on August 28, 2019 (Appendix NDOW reported elk actively occupy habitat within a four-mile buffer area, but not within the Project Site. Additionally, various species of raptors were reported to possibly reside in the vicinity of the Project Site and have distribution ranges within a four-mile buffer. These include: American kestrel, bald eagle, barn owl, burrowing owl, Cooper's hawk, ferruginous hawk, flammulated owl, golden eagle, great horned owl, long-eared owl, merlin, northern goshawk, northern harrier, northern saw-whet owl, osprey, peregrine falcon, red-tailed hawk, rough-legged hawk, sharp-shinned hawk, short-eared owl, Swainson's hawk, and turkey vulture. Species which have been directly observed in the vicinity of the Project Site include bald eagle, burrowing owl, golden eagle, merlin, prairie falcon, and rough-legged hawk. NDOW also identified ten nests for eagles, hawks, falcons, and owls known to be present within ten miles of the Project Site. 4.3 Nevada Natural Heritage Program BEC also consulted with the Nevada Natural Heritage Program (NNHP) on August 29, 2019 (Appendix No at-risk taxa were reported within the Project Site or within a two-kilometer radius surrounding the project. NNHP reported habitat may be available for the following Nevada Bureau of Land Management (BLM) Sensitive Species: Mexican free-tailed bat (Tadarida brasiliensis), and the Federally Threatened Taxon, Mojave desert tortoise. 5 SPECIES CONSIDERED DURING THE REVIEW BEC biologists reviewed the information obtained from the agencies identifying species potentially present within or near the Project Site, considered the habitat requirements for those species, and evaluated the potential for the species to be present in the Project Site or to be impacted by the proposed project. The following sections summarize the results of this evaluation and provide a conclusion as to which species warrant further consideration. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 8 5.1 Migratory Birds As part of the coordination and data gathering process, the USFWS and NDOW reaffirmed that migratory birds, including raptors, are present in the area and are protected. Migratory birds are and will be present on the Project Site throughout the year, including the breeding season, and therefore, may be impacted by the proposed project. The effects on these species will be further evaluated in in this document. 5.2 Eagles Bald eagles are present within the region and likely migrate through the area throughout the year. Nesting habitat for this species includes large, old-growth trees typically found around rivers or other waterbodies. Bald eagles typically forage within these same habitats, catching fish from the water or other prey from the surrounding areas. Such habitat is not present within nor adjacent to the Project Site. Due to the lack of nesting or foraging habitat in the vicinity of the proposed project, the potential for effects on this species is negligible. Golden eagles are relatively common in southern Nevada and are known to nest in the cliffs associated with the Spring Mountains approximately 10 miles east of the Project Site. Golden eagles forage in open grasslands and shrublands, where they prey on a variety of rabbits, birds and other wildlife. The Project Site and the adjacent parcel possess no nesting habitat for this species, and while the species has been observed in the vicinity of the project, the likelihood of a golden eagle foraging in this parcel is minimal given the degree of development surrounding the site. Due to the lack of nesting and quality foraging habitat, the potential for effects on this species is negligible. 5.3 State Endangered, Protected and Game Species NDOW listed the desert tortoise as a state endangered species potentially found within this Project Site. They also listed various migratory birds as protected. Desert tortoise and migratory birds will be addressed below. NDOW reported elk actively occupy habitat within a four-mile buffer, but not within the Project Site. Due to the lack of proximity to the Project Site and it being isolated from required habitat, the potential for the project to affect elk is negligible and will not be addressed further in this document. 5.4 Federally Listed Threatened and Endangered Species USFWS listed three species as potentially occurring within the Project Site, including the southwestern willow flycatcher and Yuma clapper rail, which are listed as endangered species, and the Mojave desert tortoise, which is listed as a threatened species. 5.4.1 Southwestern Willow Flycatcher 5.4.1.1 Species Biology Empidonax traillii extimus is a subspecies of E. traillii found in the southwestern United States. It is a small perching bird less than six inches from beak to tail. It has a brownish-grey upper body, white throat, olive breast, pale-yellow belly, and two light wing bars. The southwestern willow flycatcher migrates to its breeding territories in North America by mid-May and remains in the area until August or September. The southwestern willow flycatcher requires at least 0.25 acres of habitat, a minimum of 30 feet wide, and dense vegetation. It nests in native and non-native riparian vegetation including willow, boxelder, cottonwood, tamarisk, and Russian olive. Nest building and egg laying occurs between late May and early June. Generally, the southwestern willow flycatcher builds a nest in a medium-sized bush or small tree between 6.5 and 23 feet above the ground, surrounded ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 9 by dense, riparian vegetation. The flycatcher normally has only one clutch of two to five eggs. If the first clutch fails, a second clutch will occur. The southwestern willow flycatcher is an insectivore and depends on dense riparian vegetation for its food source. It hovers over the vegetation and captures insects as they emerge from the tree/brush line. The current range of the southwestern willow flycatcher includes wintering grounds in Mexico, Central America, and possibly northern South America; breeding territories in southern California, Arizona, New Mexico, southern Utah, western Texas, southwestern Colorado, northwestern Mexico, and southern Nevada along the Virgin River, lower Muddy River, Colorado River, and Pahranagat Valley. Species decline has been predominantly caused by thinning, alteration, and/or removal of riparian vegetation. This is often the result of drought, water diversion, groundwater pumping, mismanagement of livestock, and recreational development. Although its distribution has been relatively unchanged, populations have sharply declined from historic numbers (USFWS, 2019). 5.4.1.2 Conservation Measures/Current Management Direction Current management practices for protection of the southwestern willow flycatcher emphasize the prevention of habitat loss. In situations where occupied, unoccupied suitable, or unoccupied potential habitat loss, modification, fragmentation, or degradation is unavoidable, it is recommended habitat be replaced, permanently protected, and managed within the species’ Mojave Management Unit (USFWS, 2002). 5.4.1.3 Potential for Presence in the Project Site This species is tied closely to the nesting and foraging habitat described above, which is not present within or adjacent to the proposed Project Site, as seen in the National Wetlands Inventory map in Appendix D – National Wetlands Inventory Map. Wetland areas are present at the golf course community south of the Project Site, and the species may visit this area, but the golf course does not have large stands of trees with dense understory required by this species. For this reason, the potential that the project would affect this species is negligible. 5.4.2 Yuma Clapper Rail 5.4.2.1 Species Biology Rallus longirostris yumanensis is an endangered species of marsh bird found in the southwestern United States, primarily along the lower Colorado River and tributaries in Arizona, Nevada, Utah, and California, and its range extends south to Baja California and Sonora Mexico. It is a subspecies of the Ridgeway’s rail. It is a medium-sized bird, approximately eight inches in height, with a somewhat orange, slender, down-turned bill. It has a two-toned body: gray-brown-colored above and orange-cinnamon-colored below. It is mottled brown or gray on its rump, and its cheeks and flanks are barred with black and white. The Yuma capper rail is a riparian species which requires habitats with wet substrate and dense herbaceous or woody vegetation, most often cattail or bulrush. Vegetated areas interspersed with shallow open water are preferred. Although its minimum habitat size has not been studied, the Yuma clapper rail has been observed in areas as small as two to three acres. It feeds on crayfish, small fish, tadpoles, clams, and other aquatic invertebrates (USFWS, 2019). Breeding begins at age one and nesting occurs from March to July. The Yuma clapper rail normally has one clutch of five to ten eggs each year. Two stages of molting occur for juveniles, one within a month of hatching, and the second within six to seven weeks after the first molt. At the time of the juveniles’ second molt, the adults also molt, rendering them flightless until October (USFWS, 2017) ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 10 A steep decline in Yuma clapper rail populations over the past few decades has occurred as a result of loss and degradation of available riparian habitat due to anthropogenic factors. Either human-made habitats or effluent-supported marshes managed by humans make up the remaining habitats for this species (USFWS, 2019). 5.4.2.2 Conservation Measures/Current Management Direction A federal recovery plan for the Yuma clapper rail was published in 1983, and a draft recovery plan was made available in 2010, but it has not yet been finalized. Suggested conservation measures include establishing and actively maintaining enough managed and protected marsh habitat in the species’ core range to support its long-term persistence and movement between the core habitat areas. (USFWS, 1983) 5.4.2.3 Potential for Presence in the Project Site This species is tied closely to the nesting and foraging habitat described above, which is not present within or adjacent to the proposed Project Site as seen in the National Wetlands Inventory map in Appendix D. Wetland areas present at the golf course south of the Project Site, but large areas of cattail and bulrush are not present. The species may visit this area, however, if the species is present within the golf course, it would not likely leave the wetland habitat given it requires such habitat for breeding, nesting, and foraging. For this reason, the potential that the project would affect this species is negligible. 5.4.3 Mojave Desert Tortoise 5.4.3.1 Species Biology Gopherus agassizii is a Mojave Desert species which occurs in Nevada, California, Arizona, and Utah. Desert tortoise have a high, domed shell and rugged, elephantine legs with claws used for digging. The tortoise spends 95% of its life underground, avoiding the extreme temperatures which occur in the desert. It inhabits a wide array of habitats including sandy flats, rocky foothills, alluvial fans, washes, and canyons. Their burrows can be constructed in soils as well as caliche. The desert tortoise lays one to 14 eggs in late spring to early summer and hatchlings typically hatch in two to three months. Desert tortoise consume a diet predominantly made up of wildflowers, grasses, and cacti. It is most active in spring (March to June) and fall (September to October) and can travel up to 0.75 miles a day during this time. In the winter and summer, it retreats to its burrow to escape the temperature extremes. It requires bushes or shrubs for shade and protection from predators. The largest threat to the desert tortoise is anthropogenic activities in and around the desert, especially urbanization and large-scale renewable energy projects that either fragment or degrade habitat. Other major threats include construction of roads and highways, off-highway vehicle activities, and establishment of invasive plant species (Nevada Fish & Wildlife Office, 2017). 5.4.3.2 Conservation Measures/Current Management Direction The current USFWS Revised Recovery Plan for the Mojave Population of the Desert Tortoise outlines the recovery actions for the species. A key part of conservation for this species is to preserve intact desert tortoise habitat, especially those critical to genetic connectivity (Region 8, Pacific Southwest Region, 2011). 5.4.3.3 Potential for Presence in the Project Site This species is found throughout the region in areas where suitable habitat is present and individuals have not been impacted by disease, raven predation, pets, or human activity.

A site visit and biological survey was conducted on September 3, 2019, by Rachel Schlick (Environmental Scientist, BEC) and Rachel Kistler (Environmental Scientist, BEC) for the western half of the Project Site. The team walked transects across this portion of the Project Site and documented sign of biological resources observed. An additional survey was conducted on September 18, 2019, by Danielle Viglione (Biologist, BEC) and Kistler for the eastern half of the Project Site to further characterize habitat in the area. On November 5, 2019, a desert tortoise survey was conducted on the Project Site by Danny Rakestraw (Authorized Desert Tortoise Biologist, BEC),Viglione, and Alana Holt-Hall (Biologist, BEC). Temperature during this survey were unseasonably warm and ranged from 55 degrees Fahrenheit in the morning to 75 degrees Fahrenheit by the end of the day. During this survey, the three biologists walked parallel transects across the Project Site, searching for desert tortoise or sign of their presence within the area. The biologists noted vegetation, topography, and soil types observed on the site, as well as any birds or other wildlife observed incidentally. Upon completion of the surveys within the Project Site, each biologist walked a portion of a four-mile- long transect that bisected habitat within the parcel outside the boundaries of the Project Site. The transect was delineated prior to the survey to cross what appeared to be potential habitat for desert tortoises, with the intent of crossing multiple topographic features, identifying the areas most likely to have sign of desert tortoise presence. The biologists used the delineated transect as a guide, but meandered small ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 12 distances from the line if pockets of high-quality habitat were observed, such as rock or caliche outcrops, incised washes, or patches of unique vegetation. 6.2 Site Characterization Results 6.2.1 Site Characterization – Project Site The Project Site is located along an interface of an alluvial fan and incised terraces from a lacustrine formation, and as such, natural outcrops of fine sandy and silty soils and rolling hills were observed on the eastern portion of the site (Appendix A, Photo the western portion had fairly level topography (Appendix A, Photo The list of species observed on the site is provided in Table 6-1. Table 6-1: Plant species observed during site visits and surveys Common Name Scientific Name Common Name Scientific Name Catclaw Acacia Accacia greggii Small-leafed Ratany Krameria erecta Cattle Saltbush Atriplex polycarpa Red Brome Bromus rubens Creosotebush Larrea tridentata Redberry Desert-Thorn Lycium andersonii Desert Prince’s Plume Stanleya pinnata Rubber Rabbitbrush Ericameria nauseosa Halogeton Halogeton glomeratus Shadscale Atriplex confertifolia Mediterranean Grass Schismus barbatus Spiny Herb Chorizanthe rigida Mesquite Prosopis glandulosa White Bursage Ambrosia dumosa Mormon Tea Ephedra nevadensis Winterfat Ceratoides lanata Prickly Russian Thistle Salsola tragus Wooly Mullein Verbascum thapsus The dominant vegetation across the majority of the Project Site, primarily within the light-colored, silty soil, was a mix of both the Sonora-Mojave Creosotebush-White Bursage Desert Scrub and Sonora- Mojave Mixed Salt Desert Scrub vegetation communities described in Section 3.2. Dominant vegetation included a mix of areas of a relatively sparse and relatively dense stands of shadscale, cattle or allscale saltbush, and large specimens of creosotebush (Appendix A, Photos 7 – as well as several small but dense stands of rubber rabbitbrush (Appendix A, Photo 10). White bursage, winterfat, Mormon tea, Mediterranean grass and red brome also were present. The vegetation on the small sections of the darker soils shown in Figure 1-1 was more indicative of the Sonora-Mojave Creosotebush-White Bursage Desert Scrub, with sparse vegetation dominated by creosotebush and white bursage (Appendix A, Photo 11). Redberry desert-thorn, small leafed ratany, Mormon tea, were also present in these areas. The bare areas between the vegetation often was undisturbed desert pavement. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 13 Figure 6-1: Map of Surveyed Area, Transect, Burrows, and USFWS Potential Tortoise Habitat The non-native species red brome, halogeton, Russian thistle, and Mediterranean grass were observed on the site, primarily in disturbed sites including the multi-purpose field (Appendix B, Photo but no noxious weeds were seen. Salt-dependent species indicative of the North American Warm Desert Playa were not observed within the Project Site or within the parcel. No large trees, riparian habitat, or wetland vegetation was observed anywhere within the Project Site or the adjacent parcel. 6.2.2 Site Characterization – Remaining Parcel and Adjacent Area The soil, topography and vegetation within the remainder of the parcel was similar to the habitat described for the Project Site, but the relative abundance was substantially different. The northern, up- gradient portions of the remainder of the parcel on the alluvial fan and are dominated by the Creosotebush-White Bursage Desert Scrub vegetation association. This area includes large flats of unvegetated desert pavement, as well as areas of moderate vegetation density and vegetated washes (Appendix A, Photos 12-15). This portion of the parcel is also bisected by areas of the lacustrine deposits and Mixed Salt Desert Scrub vegetation observed in the Project Site. No wetlands, riparian habitat, large trees, or other unique vegetation or other characteristics were observed within the parcel. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 14 The area surrounding the Project Site and the parcel has been developed or disturbed to varying degrees. Immediately south of the parcel, between the boundary and Gamebird Road, residential development was initiated with the blading of areas for roads and pads. This area includes Mixed Salt Desert Scrub vegetation and disturbed land with dense stands of Russian thistle, halogeton, and red brome (Appendix A, Photo 16). The area to the west of the Project Site and the parcel is relatively undisturbed Mixed Salt Desert Scrub, primarily stands of cattle saltbush (Appendix B, Photo The area to the northwest of the parcel is developed or under development for commercial use. The north and northeast portion of the parcel is bounded by State Highway 160, and other commercial or industrial development beyond that. 6.3 Survey Results 6.3.1 Project Site Biologists surveyed the undeveloped portions of the Project Site and found no tortoises and no recent or definitive signs of desert tortoise presence within the area. Five burrows were observed within the Project Site which had the potential to be considered constructed or used by desert tortoises, though none of the burrows showed signs of recent use by any animal (Table 6-2; Figure 6-1). Three burrows were clearly abandoned, mostly-collapsed predator burrows, based on their shape and general appearance (Burrows B1 – B3). Two burrows had collapsed to the extent that an assessment of what species may have constructed or inhabited it was not possible (Burrows B4 and B5). It seemed the burrows could have been rodent burrows that had been excavated by a predator, a tortoise, or had simply collapsed. Rodent burrows throughout the area had collapsed giving the initial appearance of the half-moon shape at the entrance, but rounded to a typical rodent hole shape inside the entrance. No sign of tortoise use was present scat, tracks or other indicators) within or adjacent to any of these burrows, or throughout the Project Site. In addition, no desert tortoise scat, carcasses, or other indicators of past use of the site were observed. The soils present throughout the majority of the Project Site are the fine sandy loam that is consistent with the lacustrine deposits and lake terraces in the region and as mapped in the soil surveys. The soil does not provide sufficient structure to hold a large burrow required for an adult desert tortoise. While the area is bisected by washes, the soils do not form the clay layers or caliche that often provides effective refuge for larger tortoises. The small inclusions of the gravelly soils were similarly devoid of tortoise sign or other burrows. Generally, the biologists noted the relatively low abundance of rodent or other burrows throughout this habitat. 6.3.2 Remainder of the Parcel The results from the survey along the transect within the remaining portions of the parcel were similar to those in the Project Site. While the habitat appeared to be more conducive to the presence of desert tortoises than the habitat within the Project Site, no definitive sign of the species being present was observed. Three burrows were observed and documented. Two burrows adjacent to each other were partially collapsed. Burrow B6 appeared to be a caliche den used by rodents, small predators and possible tortoises, though no scat, tracks or other indicators that tortoises had been in the burrow were present. Burrow B7 was similar to the burrows in the Project Site in that it was mostly collapsed and the species responsible for constructing it could not be confirmed. This burrow had no sign of desert tortoise activity. Burrow B8 was the most distinct burrow on the site and was clearly a canid den based on the round entrance and relatively vertical tunnel, though it had partially collapsed as well. This burrow also lacked any sign of tortoise activity. No desert tortoise scat, tracks, carcasses, or other sign were observed along this transect. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 15 Table 6-2: Burrows Observed within the Project Site Burrow ID Type Condition/Description Location Photo Number B1 Predator 8” wide, 6” tall, 12” deep; can see back; partially collapsed; no sign Project Site 17 B2 Predator 6” wide, 6” tall, 14” deep; can see back; partially collapsed; no sign Project Site 18 B3 Predator 9” wide, 4” tall, 18” deep; can see back; partially collapsed; no sign Project Site 19 B4 Unknown 14” wide, 4” tall, 10” deep; can see back; partially collapsed; no sign Project Site 20 B5 Unknown 10” wide, 3” tall, 6” deep; can see back; mostly collapsed; no sign Project Site 21 B6 Unknown 8” wide, 4” tall, 10” deep; can see back; collapsed; no sign Parcel 22 B7 Unknown 8” wide, 4” tall, 30” deep; can see back; collapsed; no sign Parcel 23 B8 Predator 9” wide, 9” tall, 24” deep; can see back; partially collapsed; no sign Parcel 24 The habitat along this transect was dominated by creosotebush and white bursage. The area included areas with very sparse vegetation and substantial desert pavement; flat areas with substantial vegetation but no erosional features other than sheet flow; and occasional washes bisecting the area. As with the Project Site, very few sign of other wildlife was observed in this area. 7 EFFECTS ANALYSIS 7.1 Migratory birds Migratory birds use vegetation in this region for foraging and nesting and are likely to use the Project Site in the same manner. The species composition in the area likely varies seasonally. While surveys for migratory birds and bird nests were not conducted, migratory birds were observed in the Project Site during multiple site visits, including common raven (Corvus corax), chipping sparrow (Spizella passerina), white crowned sparrow (Zonotrichia horned lark (Eremophila alpestris), and loggerhead shrike (Lanius ludovicianus). One ball-shaped nest, indicative of being constructed by a Verdin (Auriparus flaviceps), was observed in the Project Site. No sign of burrowing owls or raptors nests were observed. Construction activities occurring outside the breeding season likely would have minimal direct effects on migratory birds as they would be able to move from the sites in advance of the activities. However, activities conducted during the breeding season (generally February/March through August) have the potential to impact active bird nests those with eggs or young) and doing so may be considered a “take” and would therefore be illegal under the MBTA. Avoidance of such take would require vegetation removal activities be conducted during periods other than the breeding season, or to have qualified biologists conducting surveys in advance of construction activities and establishing buffers around active nests. Activities would be required to avoid the buffer areas until a qualified biologist has determined and documented the nest is no longer active, either due to failure of the nest or the young having fledged. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 16 7.2 Eagles No large cliffs are present in the Project Site to be used by golden eagles for nesting, nor large trees and water ways for bald eagles. While the open desert of the parcel is potential foraging habitat for the golden eagles, the significant level of development on adjacent parcels may deter the species from using this area for foraging. Likewise, typical foraging habitat of bald eagles is not present and the development of the adjacent area would deter nesting habitat on site for either species. For these reasons, the project likely would not affect these species. 7.3 Threatened & Endangered Species 7.3.1 Southwestern Willow Flycatcher Marginal habitat may be present on the golf course south of the Project Site, but no habitat is present within the Project Site to attract this species for foraging or nesting. Therefore, the project likely would not affect this species. 7.3.2 Yuma Clapper Rail Marginal habitat may be present on the golf course south of the Project Site, but no habitat is present within the Project Site to attract this species for foraging or nesting. Therefore, the project likely would not affect this species. 7.3.3 Mojave Desert Tortoise Based on the presence of potentially suitable habitat within or adjacent to the Project Site, a more detailed review of the species and the potential for effects was conducted. This section provides a summary of the prior consultations with the agencies regarding this parcel, a summary of potential effects on the tortoise, and potential mitigation measures if effects on the species are identified. 7.3.3.1 Consultation History In 1998, the Service issued a Biological Opinion to BLM associated with the potential effects on desert tortoises from the issuance of a lease to the Town of Pahrump for the subject property under the Recreation and Public Purposes Act (USFWS, 1998). In 1999, a portion of this land was patented directly (without a proper lease) to the Town of Pahrump at the direction of Congress. However, development was not initiated and the terms and conditions of the Biological Opinion were not implemented. In 2008 the USFWS wrote a letter titled “Federal Agency Compliance with Section 7 of the Endangered Species Act for the Proposed Pahrump Arts and Recreational Complex Project, Nye County, Nevada” to HUD informing the agency that the terms and conditions of the 1998 Biological Opinion had not been implemented and that the Biological Opinion had expired. In 2012, the Town of Pahrump obtained federal grant funding from HUD to construct the Fox Avenue access road, the parking area, a water supply system, and a fenced multipurpose field. As the proposed project was a federal project due to the funding source, the Town of Pahrump and HUD initiated informal consultation with the USFWS to assess the potential effect of the project on desert tortoises. During the course of the informal consultation, the USFWS conducted a site visit and developed a map delineating potential desert tortoise habitat within the parcel (Figure 6-1 and Appendix The 2012 Biological Opinion effect determination for that project was “may affect, not likely to adversely affect” the species due to the potential for a tortoise to move into the Project Site from the adjacent portions of the parcel. As a result of that determination, the Town of Pahrump and the USFWS ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 17 determined several mitigation measures were warranted to minimize the risk of potential impacts on the tortoise. Construction worker environmental awareness education, providing an on-call trained responder, and construction of a tortoise exclusion fencing and a tortoise guard around the development listed above were implemented prior to and during construction. 7.3.3.2 Potential Effects on Desert Tortoises Direct Effects Direct effects are defined as effects from the project that are direct or immediate on the individuals or their habitat. Direct effects on tortoises from a project may include death or injury from construction or operation of construction equipment or vehicles, death or injury from hazards generated on the Project Site, or harassment of tortoises in the form of relocating them out of harm’s way. Direct effects may also result from the conversion of suitable habitat for development. For the proposed project, the likelihood of direct effects from the construction or operation of the facilities is negligible to non-existent. As the survey results indicate, the habitat within the proposed Project Site is not suitable for desert tortoises. The soils in the area do not provide the structure needed for effective burrows. The map of potentially suitable habitat generated by the USFWS concur with this assessment. The remaining area within the parcel was mapped as “potential suitable habitat”, but the transect walked by biologists found no indications of tortoise presence, and marginally suitable habitat. Additionally, the Project Site in particular, and the entire parcel in general, has become isolated from undisturbed, occupied tortoise habitat. The areas to the south and west of the parcel are partially disturbed salt desert scrub habitat similar to the habitat found in the southwest portion of the Project Site. Beyond those areas, the golf course and residential development have further isolated the parcel. State Highway 160 bounds the remainder of the parcel to the north and east. This heavily travelled, two-lane highway is not bounded by tortoise exclusion fencing, but the width of the highway shoulder in this area is a significant barrier to tortoise movement. Also, a significant majority of the land north of the highway has been developed as a raceway, commercial property, and mining operations. One area north of the highway to the northeast of the parcel has not been developed and is open to occupied tortoise habitat. Based on the lack of tortoise sign or suitable habitat within the Project Site, the poor quality of potential habitat, lack of sign in the adjacent portions of the parcel, and isolated nature of the area, the likelihood of a tortoise being present, and therefore affected by the project, is negligible. Indirect Effects Indirect effects are effects that are caused by or will result from the proposed action and are later in time, but are still reasonably certain to occur. No indirect effects were identified as being likely to occur. Cumulative Effects Under the ESA, cumulative effects are those effects of future State or private activities, not involving Federal activities, that are reasonably certain to occur within the Action Area of the Federal action subject to consultation. The Action Area for this project was defined as the Project Site, which is owned and managed by the Town of Pahrump. Likewise, the remaining portions of the current parcel are owned and managed by the Town of Pahrump. Given the areas within the Action Area and within the remaining parcel are reasonably certain to be developed at some point in the future, the effects from the current project and from the future development are likely to be cumulative. However, given the lack of sign of desert tortoise and relatively poor habitat within the project or throughout the parcel, the cumulative effects of the current project and any future activities in these areas are likely to be negligible or non- existent. ---PAGE BREAK--- Pahrump Fairgrounds Development Area Biological Evaluation January 6, 2020 18 8 CONCLUSIONS Federally listed threatened species may be affected through implementation of the proposed project. Federally listed endangered species are not likely to be affected through implementation of the proposed project. The proposed action would result in temporary and minor impacts to vegetation and soils. Incidental mortality or displacement among small, common, animals may occur on the site during clearing and construction. Desert tortoise habitat may be impacted in the long term, especially during future development of the Project Site. 8.1 Determination of Effects on Migratory Birds Although only one migratory bird nest was observed during the site visits, surveys for bird nesting activity during the migratory bird season (January 1 through September 30) are recommended to avoid disturbances to migratory birds. 8.2 Determination of Effects on ESA-Listed Species 8.2.1 Southwestern Willow Flycatcher Based on the lack of suitable riparian habitat on or in the vicinity of the Project Site, BEC recommends a “no effect” determination for impacts to the southwestern willow flycatcher. 8.2.2 Yuma Clapper Rail Based on the lack of suitable riparian habitat on the Project Site, BEC recommends a “no effect” determination for the Yuma clapper rail. 8.2.3 Mojave Desert Tortoise Based on the lack of suitable habitat on the Project Site; the marginally suitable, apparently unoccupied habitat within the remaining portions of the parcel, and effective isolation of the site from suitable habitat beyond the parcel, BEC recommends a “no effect” determination for the Mojave desert tortoise. 9 LIST OF AGENCIES CONTACTED Obtained data from Eric Miskow, Biologist/Data Manager, Nevada Natural Heritage Program.

Sahara Ave Las Vegas, Nevada 89117 Re: Pahrump Fairgrounds Detention Basin Dear Rachel Kistler: I am responding to your request for information from the Nevada Department of Wildlife (NDOW) on the known or potential occurrence of wildlife resources in the vicinity of the Pahrump Fairgrounds Detention Basin located in Nye County, Nevada. In order to fulfill your request an analysis was performed using the best available data from the NDOW’s wildlife occurrences, raptor nest sites and ranges, greater sage- grouse leks and habitat, and big game distributions databases. No warranty is made by the NDOW as to the accuracy, reliability, or completeness of the data for individual use or aggregate use with other data. These data should be considered sensitive and may contain information regarding the location of sensitive wildlife species or resources. All appropriate measures should be taken to ensure that the use of this data is strictly limited to serve the needs of the project described on your GIS Data Request Form. Abuse of this information has the potential to adversely affect the existing ecological status of Nevada’s wildlife resources and could be cause for the denial of future data requests. To adequately provide wildlife resource information in the vicinity of the proposed project the NDOW delineated an area of interest that included a four-mile buffer around the project area provided by you on Tuesday, August 27, 2019. Wildlife resource data was queried from the NDOW databases based on this area of interest. The results of this analysis are summarized below. Big Game - Occupied elk distribution exists outside of the project area within portions of the four-mile buffer area. No known occupied bighorn sheep, mule deer, or pronghorn antelope distributions exist in the vicinity of the project area. Please refer to the attached maps for details regarding big game distributions relative to the proposed project area. Greater Sage-Grouse - There is no known greater sage-grouse habitat in the vicinity of the project area. Raptors - Various species of raptors, which use diverse habitat types, may reside in the vicinity of the project area. American kestrel, bald eagle, barn owl, burrowing owl, Cooper's hawk, ferruginous hawk, flammulated owl, golden eagle, great horned owl, long-eared owl, merlin, northern goshawk, northern harrier, northern saw-whet owl, osprey, peregrine falcon, red-tailed hawk, rough-legged hawk, sharp- shinned hawk, short-eared owl, Swainson's hawk, and turkey vulture have distribution ranges that include the project area and four-mile buffer area. Furthermore, bald eagle, burrowing owl, golden eagle, merlin, prairie falcon, and rough-legged hawk have been directly observed in the vicinity of the project area. Raptor species are protected by State and Federal laws. In addition, bald eagle, burrowing owl, California spotted owl, ferruginous hawk, flammulated owl, golden eagle, northern goshawk, peregrine falcon, prairie falcon, and short-eared owl are NDOW species of special concern and are target species for conservation as outlined by the Nevada Wildlife Action Plan.

The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. September 03, 2019 ---PAGE BREAK--- 09/03/2019 Event Code: 08ENVS00-2019-E-00287 2 A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.), and projects affecting these species may require development of an eagle conservation plan (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Guidance for minimizing impacts to migratory birds for projects including communications towers cellular, digital television, radio, and emergency broadcast) can be found at: http:// www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm; http:// www.towerkill.com; and http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/ comtow.html. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act.

Any person or organization who plans or conducts activities that may result in impacts to migratory birds, eagles, and their habitats should follow appropriate regulations and consider implementing appropriate conservation measures, as described below. 1. The Migratory Birds Treaty Act of 1918. 2. The Bald and Golden Eagle Protection Act of 1940. 3. 50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a) The birds listed below are birds of particular concern either because they occur on the USFWS Birds of Conservation Concern (BCC) list or warrant special attention in your project location. To learn more about the levels of concern for birds on your list and how this list is generated, see the FAQ below. This is not a list of every bird you may find in this location, nor a guarantee that every bird on this list will be found in your project area. To see exact locations of where birders and the general public have sighted birds in and around your project area, visit the E-bird data mapping tool (Tip: enter your location, desired date range and a species on your list). For projects that occur off the Atlantic Coast, additional maps and models detailing the relative occurrence and abundance of bird species on your list are available. Links to additional information about Atlantic Coast birds, and other important information about your migratory bird list, including how to properly interpret and use your migratory bird report, can be found below. For guidance on when to schedule activities or implement avoidance and minimization measures to reduce impacts to migratory birds on your list, click on the PROBABILITY OF PRESENCE SUMMARY at the top of your list to see when these birds are most likely to be present and breeding in your project area.

Breeds Dec 1 to Aug 31 Long-billed Curlew Numenius americanus This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. Breeds elsewhere Rufous Hummingbird selasphorus rufus This is a Bird of Conservation Concern (BCC) throughout its range in the continental USA and Alaska. Breeds elsewhere Probability Of Presence Summary The graphs below provide our best understanding of when birds of concern are most likely to be present in your project area. This information can be used to tailor and schedule your project activities to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ “Proper Interpretation and Use of Your Migratory Bird Report” before using or attempting to interpret this report. Probability of Presence ( ) Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your project overlaps during a particular week of the year. (A year is represented as 12 4-week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated? The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. ---PAGE BREAK--- 09/03/2019 Event Code: 08ENVS00-2019-E-00287 3 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. Breeding Season ( ) Yellow bars denote a very liberal estimate of the time-frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort ( ) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 64 surveys. No Data ( ) A week is marked as having no data if there were no survey events for that week. Survey Timeframe Surveys from only the last 10 years are used in order to ensure delivery of currently relevant information. The exception to this is areas off the Atlantic coast, where bird returns are based on all years of available data, since data in these areas is currently much more sparse.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures and/or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the migratory birds potentially occurring in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC) and other species that may warrant special attention in your project location. The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the AKN Phenology Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey, banding, and citizen science datasets . Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering, migrating or present year-round in my project area? ---PAGE BREAK--- 09/03/2019 Event Code: 08ENVS00-2019-E-00287 5 To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Non-BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non-eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report ---PAGE BREAK--- 09/03/2019 Event Code: 08ENVS00-2019-E-00287 6 The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ “What does IPaC use to generate the migratory birds potentially occurring in my specified location”. Please be aware this report provides the “probability of presence” of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the “no data” indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ “Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds” at the bottom of your migratory bird trust resources page. ---PAGE BREAK--- 09/03/2019 Event Code: 08ENVS00-2019-E-00287 1 Wetlands Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes.

Calvada Blvd., Ste. 200 Pahrump, NV 89048 Re: Pahrump Fairgrounds Development Area, Nye County, Nevada (UT 2020-6210) Dear Ms. McKee: The Nevada State Historic Preservation Office (SHPO) has reviewed the subject documents received December 12, 2019 in accordance with Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended. Nye County (County) has submitted the documents on behalf of the Town of Pahrump (Pahrump) and the U.S. Department of Housing and Urban Development (HUD). Project Description The County proposes to use Community Development Block Grant funds to develop the southwestern portion of the Pahrump Fairgrounds. This development will include the construction of a flood control system and a community development center. Area of Potential Effect (APE) The County has determined that the APE for this undertaking is an area approximately 375 acres in size that includes the 75.5-acre project area plus a buffer for visual effects. The SHPO concurs with the adequacy of the APE as defined. Identification and Evaluation of Historic Properties Archaeology: In order to determine the archaeological sensitivity of the 75.5-acre project area (Direct APE), the SHPO consulted the Nevada Cultural Resources Inventory System (NVCRIS) on behalf of the County. According to these records, the Direct APE been partially inventoried for archaeological resources and sites were recorded within this area. Because this undeveloped parcel has the potential for significant archaeological properties to be present, the SHPO recommends that an archaeological inventory of the direct physical APE be completed by a Secretary of the Interior- qualified archaeologist. The survey should include all areas where direct ground disturbance will occur. 901 S.

In accordance with Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended, the Nevada State Historic Preservation Office (SHPO) reviewed the subject documents. In a letter dated January 9, 2020, the Nevada SHPO recommended an archeological inventory of the direct Area of Potential Effect (APE) be completed by a Secretary of the Interior (SOI)– qualified archeologist. In this initial letter, the SHPO stated the survey should include all areas where direct ground disturbance would occur. In a follow up teleconference with Jessica Axsom, SHPO Review and Compliance Archeologist, and Victor Villegran, SWCA Environmental Consultants (SWCA) SOI-qualified archeologist, and Rachel Schlick, BEC Environmental, Inc., on February 13, 2020, Ms. Axsom clarified the cultural resources survey should focus on surveying and updating previously recorded cultural resources identified within the direct APE. Further, Ms. Axsom requested Jill Jensen, National Park Service, be contacted regarding the proposed action with respect to the previously recorded cultural resources. SWCA archeologists performed the revisit of resource 26NY8715 on March 24, 2020, and reevaluated the resource in the Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada report (attached). Jill Jensen, National Park Service, was contacted to see if she had any concerns or recommendations for the site in question. Jensen did not have concerns or recommendations for the site. In accordance with Section 106 of the NHPA and its implementing regulations, we have reviewed the Cultural Resources Study and concur with the Eligibility Recommendation, and Conclusion and Recommendations of the SOI-qualified archeologist, included below. We request your concurrence with the finding “No Historic Properties Affected” related to the development of this project. Eligibility Recommendation Site 26NY8715 (CrNV-53-7015) is the historic Road from Bennetts Ranch to El Dorado. The site was previously recommended ineligible for the NRHP because, although it is an authentic original trail dating to the late nineteenth century, it was one of two roads between Bennetts Ranch and Stump Springs and appears to have been the more circuitous and therefore less traveled of the two routes. In addition, the previous site form notes the road is heavily disturbed ---PAGE BREAK--- ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada APRIL 2020 PREPARED FOR Nye County PREPARED BY SWCA Environmental Consultants ---PAGE BREAK--- CULTURAL RESOURCES STUDY FOR THE PAHRUMP FAIRGROUNDS DEVELOPMENT AREA, NYE COUNTY, NEVADA Prepared for Nye County Prepared by Mary Ann Vicari, M.A., RPA SWCA Environmental Consultants 7210 Placid Street Las Vegas, Nevada 89119 (702) 248-3880 www.swca.com SWCA Project No. 60827.01 SWCA Cultural Resources Report No. 20-241 April 2020 ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada i ADMINISTRATIVE SUMMARY Report Title.

A 75.5-acre area of potential effects (APE) was defined for the project. In consultation with the Nevada State Historic Preservation Office (SHPO), it was determined that the project did not require a full cultural resources inventory; however, SHPO requested a cultural resources study focused on surveying and updating previously recorded cultural resources identified within the APE. SWCA conducted a site revisit and updated the site record for the single previously recorded site within the APE, which consisted of a historic road (26NY8715). The study was conducted as part of Section 106 consultation for the project’s Environmental Assessment. The project is located on private land in Pahrump, Nevada; U.S. Department of Housing and Urban Development (HUD) represents the lead agency for the project. The cultural resources study was conducted in accordance with the Nevada Bureau of Land Management (BLM) Cultural Resource Inventory General Guidelines (BLM Nevada State Office 2012) and the State Protocol Agreement between the Nevada BLM and the Nevada State Historic Preservation Office (BLM and SHPO 2014:18). The study included a records search, a pedestrian survey of site 26NY8715, updating and evaluating site 26NY8715, and preparation of this report. PROJECT AREA The APE (project area) consists of a 75.5-acre block located in Sections 32 and 33, Township 20 South, Range 54 East, Mt. Diablo Meridian, on the Pahrump, Nevada, U.S. Geological Survey (USGS) 7.5- minute quadrangle (Figure 1; see also Appendix The project area is located on undeveloped private lands within the town of Pahrump, Nye County, Nevada, west of the intersection of Nevada State Route 160 (SR 160) and Gamebird Road. ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 2 Figure 1. Location of the Pahrump Fairgrounds APE. ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 3 ENVIRONMENTAL BACKGROUND Geology and Physiography The project area is located in Pahrump Valley within the Basin and Range physiographic province in a transitional zone between the Mojave Desert and the southern Great Basin (Mayer et al. 2012). The Great Basin is characterized by alternating, evenly spaced, subparallel mountain ranges and alluviated basins formed as the result of Late Miocene (30–40 million years ago) tectonics (Dohrenwend 1987). Pahrump Valley is bounded to the north and east by the Spring Mountains, to the west by the Resting Spring and Nopah Ranges in California, and to the south by the Kingston Range of California. The valley floor, where the project area is located, occurs between 2,500 and 2,800 feet above mean sea level. The project area is situated on a southwest-facing alluvial fan. Landforms consist primarily of fan remnant surfaces and shallowly incised ephemeral drainage channels. The northern portion of the project area contains distal fan sediments consisting of alluvial reworked older basin deposits. These deposits interfinger with inset Holocene-aged eolian silt and alluvial silts and muds in the southern portion of the project area (dePolo et al. 1999). Climate Pahrump Valley has an average maximum January temperature of 14.3 degrees Celsius (57.7 degrees Fahrenheit and an average maximum July temperature of 38.4°C (101.1°F). During January and July, minimum temperatures are −2.9°C (26.8°F) and 19.3°C (66.8°F), respectively. Average annual precipitation was 12.0 cm (4.72 inches) during the period of record. Precipitation patterns are bimodal, with peaks during warm and cool months separated by intervals of low rainfall. Pahrump receives approximately 70 percent of its annual precipitation between November and May (Western Regional Climate Center 2019). Cold season precipitation originates over the Pacific and is delivered to the area by the Westerlies. The remaining annual precipitation falls between June and September and occurs as convective thunderstorms when moist air masses travel inland from the Gulf of California (Mayer et al. 2012). Hydrology Water in Pahrump Valley is derived from the percolation of runoff through alluvial deposits at the base of the mountains and from precipitation that falls to the valley floor. Surface runoff drains towards Stewart Lake, located in the northwest part of the valley in California, or towards the dry Pahrump Lake, located in the central part of the valley. Groundwater is confined to the margins of the dry lakes and along the base of alluvial deposits originating from the Spring Mountains (California Department of Water Resources 2004). Flora and Fauna The project area is located within the Sonora-Mojave vegetation zone. Vegetation cover in the project area consists of Mojave dominated by creosote bush (Larrea tridentata) and burrobush (Ambrosia dumosa), with scattered Mojave yucca (Yucca schidigera) (SWCA 2019). The project area is located within the Mojave Desert ecoregion, which provides habitat for numerous species of mammals, including bighorn sheep, mule deer, elk, coyote, common gray fox, bobcat, cougar, ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 4 western spotted skunk, American badger, ringtail, bats, black-tailed jackrabbit, desert cottontail, mountain cottontail, Botta’s pocket gopher, and rats and mice (USGS 2007). Soils and elevation data suggest that the project area has suitable habitat for desert tortoise (SWCA 2019). HISTORIC OVERVIEW Early Exploration and Transportation By the late 1700s, Spain had established large commercial colonies throughout present-day New Mexico and southern California. The desire to link the two areas without having to negotiate the Grand Canyon resulted in the famous expedition of Francisco Dominguez and Father Silvestre Velez de Escalante in 1776. The Spanish friars and eight companions left New Mexico in search of a more northerly overland route between Santa Fe and Monterey, California (Swanson 1995:76), but were ultimately impeded by bad weather. Although the explorers failed to achieve their primary objective, their field notes provide some of the first historic-period accounts of the Native inhabitants and regional landscape. This route, combined with the trails explored by Father Francisco Garcés in 1776 and Jedediah Smith in 1826, was later incorporated into the Old Spanish Trail. During the years of Mexican ownership, Jedediah Smith became the first Euro-American explorer to venture through the Great Basin region when he followed the Colorado River along Nevada's southern border. In 1826, he became the first Euro-American to enter Nevada, crossing the future border near the modern town of Mesquite, 80 miles east of Las Vegas (Paher 1971:12). Between 1826 and 1827, Smith passed through extreme southeastern Nevada, skirting east of Bunkerville and Moapa along the Virgin and Colorado Rivers (Elliott 1987:35; Hulse 1990:33). This route through Nevada was later utilized as a southern branch of the Old Spanish Trail. However, there is no evidence to suggest that Smith ever passed through Pahrump Valley (McCracken 1992). Two years after Smith’s expedition, the Mexican trader Antonio Armijo completed the route between New Mexico and the California coast initiated by Dominguez and Escalante, finishing in Los Angeles rather than Monterey. The trail exited southern Utah and crossed through northwestern Arizona before entering Nevada near Bunkerville. From here, the route curved to the southwest, passing through the future site of Las Vegas before entering Alta, California (Elliott 1987:35; Hulse 1990:33). Armijo’s party was the first recorded group to enter Las Vegas Valley, camping along Las Vegas Wash en route to Cottonwood Spring at the present site of Blue Diamond, Nevada. According to traditional interpretations, Armijo’s party then crossed the Spring Mountains into Pahrump Valley with a stop at Stump Springs, and another at Resting Spring, also known as Archilleta or Agua de Hernandez. A few days later, the party reached the Mojave River, which they followed to Los Angeles (Paher 1971:13). Explorer and politician John C. Frémont visited the Las Vegas Valley on May 3, 1844, approaching the valley from the west with a large caravan of scouts, pack animals, and livestock. On his route, Frémont traveled through Resting Spring, Potosi Spring, Cottonwood Spring, passing northwest of Las Vegas Springs before traversing the dreaded Jornada de Muerto (Myhrer et al. 1990:5; Paher 1971:15–16). There is some indication that prior to John C. Frémont’s 1844 expedition through Las Vegas Valley, the southern route established by Jedediah Smith was more heavily used (Blair et al. 1999:28). However, after the 1845 publication of Frémont’s report of his topographical expedition, in which he labels his route as the Old Spanish Trail, traffic along the main route through the Las Vegas Valley increased dramatically. The inauguration of the Spanish Trail was a watershed event. The route immediately became a major component of the trade network between the West Coast and the interior country. Development of the ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 5 trail as a major trade route was spurred by the livestock industry, particularly the legal (and illegal) commerce of horses and mules purchased in California and transported east to Santa Fe. The Old Spanish Trail became the main mode of long-distance transportation for the American Southwest during the 1830s and 1840s, connecting Santa Fe to Los Angeles and completing a highway that ran from Independence, Missouri, to Los Angeles, California. Frémont’s route was used most intensively by members of the Church of Jesus Christ of Latter-Day Saints (Mormons) between 1844 and 1905 (Myhrer et al. 1990:5). Mormon pioneers, the first Euro- American group to settle southern Nevada, had arrived in the Salt Lake Valley of Utah in July 1847, after traveling for more than a year. A group of volunteers, dubbed the Mormon Battalion, was enlisted for the Mexican–American War (Swanson 1995:79). After their discharge from service in 1848, most members of the battalion traveled to northern Utah along a section of the Old Spanish Trail from Los Angeles through the Las Vegas Valley (Smart 1994:546). Thereafter, this corridor, including a portion of the Old Spanish Trail, was commonly referred to as the Mormon Road. Traffic on the eastern leg of the Old Spanish Trail diminished by the end of the Mexican War in 1848, and the Mormon Trail rose to prominence as the primary commercial route connecting Salt Lake City and southern California via Las Vegas (McCracken 1992). The Mormon Trail was increasingly used after the discovery of gold in California and the accelerating interest in mining exploration in Death Valley, which attracted miners to the springs in Pahrump Valley. Over time, miners established boom camps, which provided a market for ranching operations (McCracken 1992). Mining The history of Nevada is inextricably linked to the mining industry, which not only attracted settlers to the state, but also spurred much of its economic development, facilitating the construction of towns, highways, railroads, and communications networks throughout the past two centuries. The wealth promised by the 1859 discovery of the Comstock Lode in Virginia City secured Nevada’s status as a territory and determined its later statehood (Vlasich 1981:241–242). In 1864, President Lincoln proclaimed Nevada a state, helping secure the development of mining and profits (James 1981:241). The discovery of the Comstock Lode in the hills northeast of Lake Tahoe in 1859 prompted a new wave of settlers to immigrate into the Nevada Territory, with the bulk of settlement occurring in the northwestern part of the region. Prospectors from California made their way into southern Nevada in 1860–1861 and rediscovered the Potosi Mountain (lead) mine workings in the Spring Mountain Range abandoned by the Mormons a few years earlier. Within a relatively short period of time, many miners left the area for the more lucrative silver mines of Eldorado Canyon, southeast of Las Vegas (Swanson 1995:86). In 1875, William D. and Robert D. Brown, having discovered silver and lead ore just south of Resting Spring on the Old Spanish Trail, established a townsite 6 miles southeast of Resting Spring and named it Brownsville. In anticipation of a mining boom in the area, the brothers also started a ranch and fruit orchard at Resting Spring and a sawmill in the Spring Mountains. Resting Spring soon experienced a mining rush, and by 1877, there were 400 men at the site. A British mining superintendent, James Osborne, purchased the Brownsville townsite for $100, which he renamed after Chief Tecopa, a famous Southern Paiute chief who died in Pahrump in 1904. The Tecopa mines saw success for several years, allowing local ranchers to profit. In particular, the Yount family’s Manse Ranch profited greatly from the sale of produce at the Tecopa Mine, the Pacific Coast Borax operations at Furnace Creek, and the mines in Eldorado Canyon. The Manse Ranch also supplied the mining towns of Rhyolite and Beatty, delivering hay via large horse-drawn wagons. The sale of barley, corn, beans, potatoes, beets, cabbage, onions, squash, and melons afforded greater value by ton than many of the ores recovered at local mining operations. Joseph Yount went on to establish the Yellow Pine Mining District after Chief Tecopa alerted ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 6 him to the presence of the Boss and Columbia Mines located in the Spring Mountain area (McCracken 1992). Settlement and Ranching With the passage of the Homestead Act of 1862, which provided settlers with 160-acre land allotments, the nation’s frontier continued to expand westward (Bogue 1994:289; Milner 1994:153). Nevada Territory was granted statehood in 1864, after which federal lands could be sold, allotted, auctioned, or raffled off to settlers as the State saw fit (Bogue 1994:301). However, the southern tip of present-day Nevada (including Pahrump Valley) remained part of the Arizona Territory until 1866, when Congress authorized the extension of Nevada’s boundary southward to the Colorado River (McCracken 1992). Historic ranches in the project area vicinity include Hidden Hills Ranch. The property, which eventually grew into one of the largest private inholdings in Pahrump Valley, was acquired in 1922 by John B. Yount, son of pioneer Joseph Yount. At the time of the 1934 General Land Office (GLO) survey, the parcel included a home and outbuildings, along with a well and windmill. Roland Wiley purchased the ranch from Belle Yount, widow to John Yount, in 1941. At that time, Hidden Hills Ranch contained a primary 20 × 24–foot board and batten constructed cabin, but the majority of the property was undeveloped and being used as grazing land. During the 1940s, the Manse Ranch, along with the Pahrump Ranch, was devoted to the production of alfalfa, grains, and beef cattle in addition to fruits and vegetables for home consumption. Other properties, such as the Raycroft Ranch, focused on dairy cattle dairy products, which were then sold in Tecopa, Shoshone, Furnace Creek, and Las Vegas. Frank Buol grew grapes and produced wine in addition to selling fruits and nuts and operating the only store and post office in Pahrump. Starting in 1948, Leon Hughes became the first farmer in Pahrump Valley to successfully grow cotton on a large scale, using an innovative method to make cotton bales for transport and spurring a cotton boom in Pahrump Valley (McCracken 1992). In the 1970s, Roland Wiley began construction of the Cathedral Canyon, a collection of statues and artwork situated along a canyon trail on the Hidden Hills property that later became a tourist attraction. Roland Wiley was responsible for several other improvements to the general Hidden Hills Ranch area. In 1941, he brought the first motorized road grader to Pahrump Valley and bladed the road from Hidden Hills Ranch to Sandy Valley. Wiley also constructed an airstrip less than 1 mile south of the house at Hidden Hills Ranch (McCracken 1992). Famous southern Nevada Indian renegade Queho, whose body was found in a cave along the Colorado River in the early 1940s, is buried in a grave on a hill near the canyon (McCracken 1992). HISTORIC CONTEXT All sites recorded during the project were evaluated for eligibility for inclusion in the National Register of Historic Places (NRHP). The criteria for NRHP eligibility, or significance, as outlined in 36 Code of Federal Regulations 60.4, are as follows: The quality of significance in American history, architecture, archeology, engineering, and culture is present in districts, sites, buildings, structures, and objects that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and: A. that are associated with events that have made a significant contribution to the broad patterns of our history; or ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 7 B. that are associated with the lives of persons significant in our past; or C. that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or D. that have yielded, or may likely yield, information important in prehistory or history. In evaluating whether cultural resources in the project area meet any of the above criteria and retain integrity, eligibility factors and aspects of integrity specific to the types of sites identified must be considered. For properties eligible under Criterion D, such as archaeological sites that have information potential, less attention is given to their overall condition than if they were eligible under Criterion A, B, or C. Archaeological sites have undoubtedly been affected by cultural and natural formation processes that have altered the deposited materials and their spatial distributions (Little et al. 2000). Therefore, for sites that are eligible under Criterion D, integrity is based on the site’s potential to yield data that address research questions identified in the historic context (Little et al. 2000). Historic Themes To determine whether historical resources in the project area meet the criteria for NRHP eligibility, properties were evaluated for their ability to yield information pertinent to the historic theme of transportation. Transportation Early exploration trails in Nevada have served as major transportation routes since Euro-Americans first entered the region, and many have evolved into modern highways. Early route types include access roads to historic period ranches and mines. The historic Road from Bennetts Ranch to El Dorado intersects the project area. Historic SR 160 is located 0.2 mile to the northeast. The Old Spanish Trail is located approximately 14 miles south of the project area. The Old Spanish Trail segment located in Clark County, Nevada, was first listed in the NRHP in 2001 and covered the portion of the trail that extends from the California border to Arizona and through Las Vegas, Nevada. Portions of the trail are listed in the NRHP and considered contributing elements of the Old Spanish Trail–Mormon Trail Historic District. Property types associated with the early transportation theme in the project area are thus likely to include trails, two-track roads, and paved roads the Old Spanish Trail) with associated features such as construction camps and roadside refuse scatters. Historic period roads are generally two-track dirt roads with vegetation growth between the tire ruts. Early transportation sites representing newly established corridors connecting small, previously isolated towns with larger cities will be considered eligible for the NRHP under Criterion A. If a site can be documented as having an important relationship to an individual who played a significant role in the history of historic transportation, it is eligible under Criterion B. If a site is clearly associated with an individual or expedition party important to early transportation in the region, it will also be considered eligible under Criterion B. If the association is unclear or there is no archival evidence of the individual’s importance, the site will be determined ineligible. Early transportation sites eligible under Criterion C would exhibit unique or innovative types of construction or engineering. If a site displays unusual construction techniques or engineering characteristics, or other unique features such as wagon ruts worn in rock, it is also eligible under Criterion C. A trail will be considered to retain sufficient integrity to be eligible for the NRHP if its original route is ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 8 unaltered or if it has been used by motor vehicles but retains its location, feeling, associations, character, natural environment, and setting. Routes that have been severely affected or that exhibit modern modifications are likely ineligible, with the exception of segments that are the last remnants of important trails. Cases in which the original trail no longer exists but can be verified through associated artifacts and/or archival records should be evaluated on an individual basis. Additional information can be gathered from the knowledge of historic period routes and trails, which could lead to a more precise chronological understanding of early exploration and settlement. A site is eligible under Criterion D if it has the potential to provide information relating to the development and use of transportation routes in the project area, specifically as it pertains to the advent of new routes, the use of new technologies during route clearance and construction, the introduction of motorized transport (such as railroads) into the region, and the impacts of transportation on Euro- American settlement of the area. PRE-FIELD RESEARCH Records Search An archaeological literature review was conducted in order to identify previous cultural resources projects and previously recorded archaeological sites within 1 mile (1.6 km) of the APE. The search included a review of cultural resources files from the Nevada Cultural Resource Information System (NVCRIS). SWCA also reviewed GLO plat maps available online through the BLM Nevada State Office, as well as historical topographic quadrangles available online through the USGS. SWCA archaeologist Mary Ann Vicari performed the NVCRIS search in March 2020, under the authority of Nevada State Antiquities Permit No. 248. Ms. Vicari also performed the historic maps search in March 2020. The literature review identified a total of 12 prior archaeological projects within 1 mile (1.6 km) of the project area, only one of which overlaps with the APE (Table In total, six archaeological sites have been previously recorded within the archival review area, one of which (26NY8715) falls within the APE (Table No architectural resources or inventories were identified within 1 mile of the APE.

The update consisted of a survey along the historic road to map the road alignment within the APE and record any associated artifacts and features. Although the project area is located entirely on private lands, the survey crew defaulted to BLM guidelines for the identification, recording, and evaluation of cultural resources (BLM Nevada State Office 2012). SWCA archaeologists Sara Rickett and Jen Durk performed the site revisit on March 24, 2020. The site was updated on a Nevada Intermountain Antiquities Computer System (IMACS) site form, photographed, and mapped using Samsung Galaxy Tablets with Juniper Geode receivers. GPS data were then exported into ESRI’s ArcView shapefile format using the Universal Transverse Mercator (UTM) Zone 11N, North American Datum 1983 (NAD 83) datum coordinate system for further processing and map production. A file geodatabase was generated in ESRI's ArcGIS 10.7, populated with field data, then used to generate all field maps. Overview photographs of the site were taken using a high-resolution digital camera, including at least two with identifiable topographic locations, to ensure easy navigation by future researchers. Finally, the site was evaluated for eligibility for inclusion in the NRHP. The evaluation was based on the historic context presented above. RESULTS SWCA updated a single previously recorded historic road site (26NY8715). No other sites or isolated occurrences were recorded during the project. Results are depicted on the map in Appendix C; the updated IMACS form is included in Appendix D. 26NY8715 (CrNV-53-7015) Site Description Site 26NY8715 (CrNV-53-7015) is the historic Road from Bennetts Ranch to El Dorado located in Pahrump Valley. A 6-mile segment of the road was recorded in 1994 by the BLM (Myhrer 1994). The road trends northwest to southeast and is depicted on the 1881 Township 20 South Range 54 East GLO plat map. The original site form notes the road was a precursor to SR 160 and ran from Bennetts Ranch to the Mormon Road southwest of Stump Springs. The route also connected the Bennetts and Yount/Manse Ranches. Myhrer (1994) also noted a scatter of household debris associated with a 200-foot undisturbed portion of the road corridor. In 2020, SWCA conducted a pedestrian survey of 26NY8715 where it transects a proposed development for the new Pahrump Fairgrounds. The updated road segment ranges from 6 and 9 feet wide and is recessed into the ground, possibly due to historic blading or as a result of repeated use and erosion. The roadbed retains water and has heavy vegetation regrowth compared to the surrounding areas, with 20%–100% ground coverage. The southern portion of the updated road segment is in poor condition due to modern ATV traffic and numerous braided two-track roads, which also form drainages. These disturbances obscure the road in this area and make it difficult to discern the original alignment. Associated artifacts include an aqua glass insulator fragment (H1) and various pieces of broken glass. Modern trash was also noted along the road. ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 11 The primary vegetation associated with the site is creosote bush. The road transects an alluvial fan surface. Eligibility Recommendation Site 26NY8715 (CrNV-53-7015) is the historic Road from Bennetts Ranch to El Dorado. The site was previously recommended ineligible for the NRHP because, although it is an authentic original trail dating to the late nineteenth century, it was one of two roads between Bennetts Ranch and Stump Springs and appears to have been the more circuitous and therefore less traveled of the two routes. In addition, the previous site form notes the road is heavily disturbed as a result of modern development and therefore lacks overall integrity. SWCA agrees with this recommendation for the updated segment. Where it crosses the current APE, the road has been significantly impacted as a result of blading, intersection of other two-track roads, alluvial erosion, and ATV use. The southern portion of the segment has been almost completely obliterated. In addition, there are no significant associated artifacts or features of research value. In summary, SWCA recommends the site as ineligible for the NRHP under any Criteria. CONCLUSION AND RECOMMENDATIONS SWCA was contracted by BEC Environmental, Inc., to conduct a cultural resources study for the Pahrump Fairgrounds Development Area, Nye County, Nevada. At SHPO’s request, SWCA conducted a site revisit and updated the site record for the single previously recorded site within the 75.5-acre APE, which consisted of a historic road (26NY8715 [CrNV-53-7015]). The study was conducted as part of Section 106 consultation for the project’s Environmental Assessment. During the site visit, SWCA fully recorded and updated the historic road site where it crosses the current project APE. The site was evaluated and recommended ineligible for the NRHP. Because no NRHP- eligible sites were identified within the APE, SWCA recommends a finding of No Historic Properties Affected for the project. ---PAGE BREAK--- Cultural Resources Study for the Pahrump Fairgrounds Development Area, Nye County, Nevada 12 REFERENCES CITED Bogue, Allan G. 1994 An Agricultural Empire.

It shows environmental and demographic raw data the estimated concentration of ozone in the air), and also shows what percentile each raw data value represents. These percentiles provide perspective on how the selected block group or buffer area compares to the entire state, EPA region, or nation. For example, if a given location is at the 95th percentile nationwide, this means that only 5 percent of the US population has a higher block group value than the average person in the location being analyzed. The years for which the data are available, and the methods used, vary across these indicators. Important caveats and uncertainties apply to this screening-level information, so it is essential to understand the limitations on appropriate interpretations and applications of these indicators.

It can help identify areas that may warrant additional consideration, analysis, or outreach. It does not provide a basis for decision-making, but it may help identify potential areas of EJ concern. Users should keep in mind that screening tools are subject to substantial uncertainty in their demographic and environmental data, particularly when looking at small geographic areas. Important caveats and uncertainties apply to this screening-level information, so it is essential to understand the limitations on appropriate interpretations and applications of these indicators. Please see EJSCREEN documentation for discussion of these issues before using reports. This screening tool does not provide data on every environmental impact and demographic factor that may be relevant to a particular location. EJSCREEN outputs should be supplemented with additional information and local knowledge before taking any action to address potential EJ concerns. For additional information, see: www.epa.gov/environmentaljustice Selected Variables Environmental Indicators Particulate Matter (PM 2.5 in µg/m3) Ozone (ppb) NATA* Diesel PM (µg/m3) NATA* Cancer Risk (lifetime risk per million) NATA* Respiratory Hazard Index Traffic Proximity and Volume (daily traffic count/distance to road) Lead Paint Indicator Pre-1960 Housing) Superfund Proximity (site count/km distance) * The National-Scale Air Toxics Assessment (NATA) is EPA's ongoing, comprehensive evaluation of air toxics in the United States. EPA developed the NATA to prioritize air toxics, emission sources, and locations of interest for further study. It is important to remember that NATA provides broad estimates of health risks over geographic areas of the country, not definitive risks to specific individuals or locations.
