(Tetra Tech) completed a Phase II Environmental Site Assessment (ESA) of the Old Dumas Seed Site (the “Site”) in Moscow, Idaho (Figure 1, Appendix The investigation was conducted as part of the Greater Moscow Area Coalition Brownfield Project. Results of a Phase I ESA completed by Tetra Tech (Tetra Tech, 2012a) and summarized in Section 1.2.3 of this report identified recognized environmental conditions (RECs) for soil and groundwater from historical use of the Site. The Phase II ESA was completed in general accordance with a sampling and analysis plan (SAP) prepared by Tetra Tech (Tetra Tech, 2012b) and the SAP addendum (Tetra Tech 2012c). This report is organized as follows: Section 1 provides an introduction; Section 2 presents the scope of work and objectives of the investigation, and Section 3 presents investigation methods. Section 4 presents results and Section 5 provides conclusions and recommendations. Appendices A and B present figures and tables referenced in the report, respectively. Appendix C presents laboratory analytical reports for soil and groundwater samples obtained during the Phase II ESA. Appendix D presents copies of field forms and Appendix E presents Idaho Department of Environmental Quality (IDEQ) risk evaluation software input and output sheets. 1.1 Site Location, History and Current Condition The Site is located at 103 North Almon Street in Moscow, Latah County, Idaho (Figure 1, Appendix The subject property is comprised of two parcels with a combined total size of approximately 1.78-acres. The Site is bounded to the north by West A Street, to the east by North Almon Street, to the west by North Asbury Street, and to the south by residential properties. The subject property does not have a uniform topographic gradient. The southeastern portion of the Site is elevated with respect to the middle of the Site and slopes down-gradient to the northwest and west. The northwestern portion of the Site is also elevated with respect to the center of the Site and slopes down-gradient to the southeast. In addition, recent building demolition activities have resulted in soil disturbance in various areas of the Site. Hogg Creek flows in a southerly direction in a ditch along the western boundary of the Site. Hogg Creek emerges from underneath West A Street at the northwestern corner of the Site and then proceeds to flow through several culverts before being redirected to the west, underneath North Asbury Street, near the southwestern corner of the Site. 1.1.1 Historical and Current Condition ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 2 The Site is a former grain, pea and lentil processing and storage facility that had operated for at least 100 years. The Site had several structures associated with the former Dumas Seed operations. The following presents a discussion of the structures as described in Tetra Tech’s Phase I ESA (Tetra Tech, 2012a). While completing the Phase I ESA of the Site in February 2012, Tetra Tech noted that several Site buildings were being dismantled in order to salvage the wood and recycle metal used to construct those structures. Salvaged lumber and beams were stacked in eastern portions of the Site at the time of the site visit, while wood and metal demolition debris was present on the southern and central portions of the Site. Mill The Mill structure (also labeled as Feed Mill on Sanborn Fire Insurance Maps) was located on the southern portion of the subject property. The Mill structure had been mostly dismantled down to the wooden floor of the 1st level at the time of the Phase I ESA site visit, with the exception of the multi-story steel and wood frame bag-house structure. The bag-house had a corrugated metal exterior and was used to capture particulate from the mill, rather than product packaging. Product storage silos formerly adjoined the Mill but were demolished at some point prior to the Phase I ESA. An approximately 10,000-gallon above-ground storage tank (AST) was located partially beneath the bag-house structure and partially inside the former Mill building. The AST was reportedly used for molasses storage and, at the time of the Phase I ESA site visit, still contained some residual molasses. The exterior of the AST was labeled that its original, intended contents were unleaded gasoline. The piping and valves for the AST were located inside the former Mill structure. Warehouse The Warehouse structure (also labeled as Seed Warehouse and Packaging on Sanborn Fire Insurance Maps) was located on the northern and northwestern portions of the Site. The building was mostly intact at the time of the Phase I ESA site reconnaissance with dismantling activities taking place on the top floor. The Warehouse was a four-story, wood post and beam structure with a corrugated metal exterior. The Warehouse was reportedly used for sorting and screening pea and lentil products and included many transfer chutes and scoop-type conveyor belts. The structure also included an electrically-powered lift/elevator. A covered load-out drive- through for farm trucks was located on the northwestern side of the Warehouse structure. Concrete ramps for the drive-through were present on West A Street and on North Asbury Street. Power Plant The Power Plant structure (also labeled as Boiler Room and Coal Bin on Sanborn Fire Insurance Maps) was located on the northeast portion of the Site and adjoined the east wall of the Warehouse. The Power Plant was mostly intact at the time of the Phase I ESA site reconnaissance. The Power Plant was a brick and mortar structure which included an approximately 60-foot tall smoke stack. The Power Plant contained a pressure vessel and grinder used to pressure cook and then to grind peas and lentils into a processed meal. Scale and Scale-House The Scale and Scale-House was located on the eastern property boundary, proximal to North Almon Street. The Scale House was a stick-built structure with both T-111 type composite wood siding and wood siding, with a pent-like roof. The truck scale adjoined the east side of the Scale House, along the eastern property boundary of the Site. An approximately 300-gallon ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 3 portable diesel AST was observed on the west side of the Scale House during the Phase I ESA site visit. The diesel AST was staged on a large wood box and was used by Rehistoric Wood Products for fueling their equipment. 1.2 Previous Investigations Previous investigations at the Site included a Phase I ESA completed by TerraGraphics in 2007 (TerraGraphics, 2007), asbestos abatement of Site structures completed by IRS Environmental in in 2007 (IRS Environmental, 2007), and a Phase I ESA completed by Tetra Tech in 2012 (Tetra Tech, 2012a). The following sections summarize each of those projects. 1.2.1 Phase I ESA Completed by TerraGraphics in 2007 Tetra Tech reviewed a copy of a previous Phase I ESA conducted for the Site by TerraGraphics in 2007. The report identified several RECs in connection with the Site:  Presence of oil stains on the second floor and main floor of the processing mill, as well as in the boiler room,  Presence of several unlabeled and labeled 5 gallon, 30 gallon, and 55 gallon drums containing insecticides, wood coatings (polyurethane and paint), lubricants and oils throughout the processing and farm store building, as well as inadequate spill containment for these containers,  Presence of mold in basement of processing mill,  Potential for asbestos in building materials throughout the entire subject property,  Potential for lead-based paint on all the buildings throughout the structure,  Historical use of fumigants and /or pesticides (pre-1974) for pest control of peas and grains,  High potential for radon inside the buildings based on the EPA classification for Latah County, and  An UST used to store automobile fuel was noted on the removal report, but reportedly no soil samples were obtained at the time of tank removal. At the time of Tetra Tech’s site visit in 2012, the mill building had been demolished to the wood floor of the first floor. Staining to the floor and mold in the mill was observed as a de minimis condition. Asbestos was removed in 2007 (see below). Given that the buildings are being demolished, radon is not a concern at this time. Tetra Tech assumes that ReHistoric has complied with all testing needed for demolition of the structures with respect to asbestos and lead based paint according to State and Federal laws. Few rooms observed in the Warehouse were painted and, given that the siding on the buildings appeared to be primarily unpainted steel, lead-based paint impacts to soil is likely a de minimis condition. 1.2.2 Asbestos Abatement Completed by IRS Environmental in 2007 IRS Environmental performed an asbestos abatement of the structures on the Site in September 2007. IRS disposed of the asbestos containing material at an EPA-approved facility. Air sample clearance results were less than 0.01 fibers per cubic centimeter. Based on the results, the buildings were cleared for demolition work. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 4 1.2.3 Phase I ESA Completed by Tetra Tech in 2012 Tetra Tech conducted a Phase I ESA at the Site in February 2012. The Phase I ESA identified the following RECs:  The Site had been used as a grain, pea, or lentil processing and storage facility for at least 100 years. Over this time pesticides, rodenticides, fumigants, and possibly fungicides have been repeatedly applied to the structures on the Site and around the exteriors of the Site structures. Metals-based pesticides, organochlorine pesticides, and organophosphate pesticides are considered RECs for soil at the Site.  An UST was located in the general vicinity of the Scale House structure for automotive fuel. This UST was reportedly removed in the 1990s. No records were found during the Phase I ESA that discussed what, if any, contamination was associated with the gasoline UST. Also, IDEQ records indicated two USTs at the Site but it was unclear as to whether the second UST had been removed. Information for the second tank indicated it was relatively small and included copper piping which suggests it had likely been used to store heating oil, possibly for a heating unit in the Scale House. There were no indications (e.g. pipes, vents, etc.) of a remaining UST in the Scale House area at the time of the Phase I ESA site visit. In the absence of data to the contrary, the potential for residual petroleum contamination in the subsurface of the Site in the area of the former UST(s) is considered to represent a REC in connection with the Site.  The residual containers of pesticides, fumigants, petroleum lubricants, and other materials left at the Site by previous owner/operators are considered to represent RECs in connection with the Site. At the time of the Phase I ESA, Mr. Jeff Williams, Project Manager for ReHistoric Wood Products, LLC (site owner), stated that ReHistoric would hire a contractor to remove the containers of pesticides, fumigants, petroleum lubricants, and other containers with residual products. As such, the SAP prepared by Tetra Tech for this Phase II ESA did not address removal and disposal of those containers. 1.3 Topography The US Geological Survey (USGS) 7.5-Minute topographic map of Moscow West depicts the Site as part of an urban, or “built-up” area of the City of Moscow located in the Southeast ¼ of Section 7, Township 39 North, Range 5 West of the Boise Meridian. The elevation of the Site is approximately 2,560 feet above mean sea level (AMSL). The topographic map indicates the ground surface in the vicinity of the Site slopes generally to the west. At the time of the February 2012 site visit, Tetra Tech observed the ground surface at the Site did not have a uniform topographic gradient. The southeastern portion of the Site was observed as elevated with respect to the middle of the Site and slopes to the northwest and west. The northwestern portion of the Site was also observed as elevated with respect to the center of the Site and slopes down-gradient to the southeast. Water at the time of the site visit accumulated between the two site structures, along the traverse of the former rail spur, and more heavily on the western to northwestern portion of the Site. 1.4 Geology and Hydrogeology The subject property is located on a small eastern embayment of the Columbia River Plateau (Alt and 1989), near the western foothills of the Rocky Mountains. The Columbia River Plateau was originally created by a series of basalt flows. Approximately 17 million years ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 5 ago basalt flows erupted to cover portions of northeast Oregon, southwest Washington and western Idaho, including the Moscow area. Intrusive granitic rocks in the Moscow-Pullman area belong primarily to the Cretaceous-Tertiary aged Idaho Batholith and commonly range in composition from quartz-monzonite to granite and quartz diorite (Alt and 1989). To the north and northeast there are undifferentiated Idaho Batholith rocks. Accompanying and following emplacement of the Idaho Batholith was a period of extensive erosion. The basalt that erupted from vents during an 11 million year period in the Miocene Era filled lowlands. The Palouse Hills of the area are silt dunes that formed when the climate of the area was extremely dry. The dunes may have been present prior to the ice ages that reached the area thousands of years ago (Alt and 1989). The Palouse Hills silt covers most of the basalt in the Moscow area, with varying thicknesses. Groundwater flow direction for the Site and site vicinity is anticipated to be in a westerly direction. This assessment was based on: 1) information provided by the Palouse Watershed Conservation District and Palouse Basing Aquifer Committee (Tetra Tech, 2012a); 2) professional knowledge of the general groundwater flow direction for the Moscow area being to the west: 3) local observations of the topography in the vicinity of the Site: 4) the general surface gradient of the site vicinity; and 4) surface drainage observed as generally being from east to west across the Site (Tetra Tech, 2012a). 1.5 Purpose of Project The City of Moscow was awarded a US EPA Brownfields Assessment Grant in August 2010 to perform assessments on properties with real or perceived contamination in the Moscow, Idaho area. The Old Dumas Seed Site was selected as one of the properties to evaluate. The Site is located within a former railroad/industrial corridor and was previously used as a grain, pea, or lentil processing and storage facility. Pesticides, rodenticides, fumigants, and possibly fungicides may have been repeatedly applied to the structures on the Site and around the exteriors of the Site structures. In addition, petroleum hydrocarbons associated with former USTs at the Site may also have impacted soil and/or groundwater. The purpose of the Phase II ESA was to investigate soil and groundwater at the Site to evaluate whether past operations at the Site have resulted in impacts to soil and/or groundwater. Results from the investigation were reviewed and compared with applicable soil screening levels and groundwater standards. A risk assessment was also performed to evaluate what, if any, potential risk the Site poses to human health and the environment. Information obtained during this investigation will be used during any potential cleanup needed and in the future to evaluate potential redevelopment options. 1.6 Contaminants of Potential Concern The Site was used as a grain, pea, or lentil processing and storage facility. Pesticides, rodenticides, fumigants, and possibly fungicides may have been repeatedly applied to the structures on the Site and around the exteriors of the Site structures. The Site also had at least one, and possibly two USTs. One UST that contained gasoline was reportedly removed in the 1990s. The other possible on-site UST potentially held heating fuel oil. It is unknown whether that tank was removed but may have serviced the Scale House with heating fuel oil for a ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 6 heating system. At the time of the Phase I ESA, there was no heating system for the Scale House other than a kerosene space heater. Based on information obtained during the Phase I ESA, Tetra Tech developed a list of contaminants of potential concern (COPCs) for the Site. The following table presents the COPCs. CONTAMINANTS OF POTENTIAL CONCERN Contaminant Origin Metal-based pesticides, organochlorine pesticides, organophosphate pesticides Pesticide application in and around site structures Metals Metals-based pesticides applied in and around site structures. Lead from possible leaded gasoline. Herbicides General site weed control, herbicides from delivered peas, lentils, and grains Gasoline-range and Diesel-range petroleum hydrocarbons USTs ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 7 2.0 SCOPE OF WORK AND OBJECTIVES The following sections present the site-specific scope of work and project objectives for this Phase II ESA. 2.1 Scope of Work The scope of work was developed based on information obtained during the 2012 Phase I ESA (Tetra Tech, 2012a) and the COPCs identified for the Site (see Section 1.7). The scope of work for this project consisted of three main tasks:  Phase II ESA: Perform both an area-wide and focused soil and groundwater investigation to address site concerns;  Risk Assessment: Perform a risk assessment using the Idaho Department of Environmental Quality (IDEQ) Risk Evaluation Manual (REM) (IDEQ 2011) for guidance to evaluate what, if any, risk contaminated soil and/or groundwater may pose to human health or the environment; and,  Phase II ESA Report: Prepare a Phase II ESA report that summarizes the investigation and presents the investigation and risk assessment results. As mentioned in Section 1.2.3, ReHistoric stated that they planned to hire a waste disposal contractor to handle the removal and proper disposal of the containers that remain on site in the Warehouse, which contain a variety of residual products. Therefore, waste disposal for contents within these containers were not included in this Phase II ESA scope of work. 2.2 Project Objectives The objective of this Phase II ESA was to complete a soil and groundwater assessment of potential environmental impacts, if any, associated with use of herbicides and pesticides, and the former USTs at the Site. The data obtained during the investigation was compared to applicable screening and/or cleanup levels. The goal of the investigation was to provide sufficient data to perform a risk assessment, and would be used in the future to evaluate potential cleanup alternatives that are protective of human health and the environment and aid in evaluating potential redevelopment plans. Data quality objectives (DQOs) for this project that were used to ensure data quality and to define procedures for data collection were defined in the SAP (Tetra Tech 2012b, 2012c). DQOs were developed in accordance with recommendations in EPA guidance documents (EPA 1994 and 1998). ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 8 3.0 PHASE II ESA INVESTIGATION METHODS The following sections present the methods of investigation that were used during this Phase II ESA at the Old Dumas Seed Site. Field work was completed in accordance with a site-specific health and safety plan (HASP) prepared for this project that met Occupational Safety and Health Administration (OSHA) requirements. Field personnel also used Tetra Tech’s Standard Operating Procedures (SOPs) presented in the SAP (Tetra Tech 2012b) as guidance during the Phase II ESA investigation. 3.1 Utility Locates Tetra Tech contacted utility locators to coordinate buried utility line locates prior to implementation of the field investigation. Surface traces of buried utilities were used, if necessary, to field-adjust the final locations of soil borings, wells, and test pits. 3.2 Deviations to the SAP Deviations to the project SAPs (Tetra Tech, 2012b and 2012c) were limited to the following:  One of eleven proposed hand excavated test pits was eliminated. The entire portion of one cell where a proposed test pit was located along the east boundary of the property (F4; Figure 2) was paved with asphaltic concrete preventing access to surface soil. Therefore, the total number of surface soil samples was reduced from 11 samples to 10 samples.  The surface soil sample designation for one hand excavated test pit was mislabeled in the field. The sample location designation used an arbitrary coordinate system (see Section 3.3.1). Surface soil sample was mislabeled in the field as DSTP-D2 Data tables presented in this report identify the correct sample name/location of the surface soil sample.  One of the six proposed boreholes located proximal to the Scale House (Figure 2) was also eliminated. The scales are located at or very near the east property boundary of the Site along North Almon Street. Utility locates indicated a potential buried water line near the east side of the scales. The proposed boring located mid-point along the north- south axis of the scales could not be installed due to the potential of encountering that water line. Moving the boring further to the east would have located the boring in the North Almon Street right-of-way and the boring could not be moved further to the west because of the scales. Therefore the total number of boreholes installed in the vicinity of the Scale House was reduced from six to five.  The trip blank supplied by the analytical laboratory was inadvertently not shipped along with groundwater samples obtained from monitoring wells installed as part of the investigation. The trip blanks were part of the quality assurance program described in Section 3.5 of this report.  Tetra Tech’s supplemental October 2012 investigation included several sampling points in the asphalt near the scale house. Field personnel attempted to break through the asphalt with a jackhammer to gain access to the underlying soil. However, the field personnel were unable to access underlying soil. Sampling points that fell over top of the ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 9 asphalt area were moved to the closest soil location to the original proposed location but off the asphalt.  Several individual sampling points during the October 2012 investigation required minor adjustments from their proposed locations due to demolition debris. 3.3 Data Evaluation The Master QAPP (TerraGraphics, 2011) was used as a general guide for personnel involved with field activities, evaluation of the data, and reporting for data evaluation for this investigation. Tetra Tech also performed data evaluations following EPA Contract Laboratory Program (CLP) national functional guidance documents for both inorganic and organic data review (EPA, 2011 and 2008, respectively). Data evaluation reviews were included in laboratory analytical data reports in the Phase II ESA report. 3.4 April 2012 Soil and Groundwater Investigation Methods The Phase II ESA field investigation consisted of three main sampling tasks:  Perform area-wide surface soil sampling to evaluate potential impacts associated with the use of pesticides, rodenticides, fumigants, and possibly fungicides that have been repeatedly applied within and around the site structures.  Perform subsurface soil sampling in the Scale House/UST area to evaluate potential petroleum hydrocarbon impacts associated with one to two former USTs at the Site.  Install and sample groundwater monitoring wells to characterize groundwater flow and quality at the Site with regards to the potential impacts related to the identified COPCs. Field personnel documented all field activities on field logs, in the field notebook, and on field maps. Photographs were taken to document site investigation activities. The following sections discuss the investigation tasks and methods. 3.4.1 Site-Wide Surface Soil Investigation The primary use of the pesticides, rodenticides, fumigants, fungicides, and herbicides was likely associated with the structures at the Site. Several structures were located across the Site which may have incorporated the use of those compounds. However, disturbance and tracking of soil over time may lead to spreading of the contaminant across the Site. Therefore, Tetra Tech developed an area-wide surface soil investigation strategy to evaluate soil across the Site for these constituents. Tetra Tech developed a 50-foot by 50-foot grid system in order to implement a systematic random sampling approach to characterize potential area-wide contaminant concentrations in surface soil. The grid system resulted in a total of 36 cells from which every third cell was designated as a potential surface soil sample location. In accordance with the project SAP (Tetra Tech, 2012b), a grab sample of surface soil was to be obtained from every third grid cell, resulting in a total of 12 potential surface soil sample locations (Figure Field personnel obtained surface soil samples from the central portion of each of the 12 sampling cells with the following exceptions: ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 10  For cells that were located in an area of high vehicular traffic and/or disturbance from site demolition activities, the sample location was adjusted in the field to an area within that cell that was less disturbed (e.g. adjacent to a site structure).  Where the center of the cell fell on a structure, where a structure occupied only a portion of the cell, or where site demolition debris occupied a portion of the cell and, therefore, prevented access to the ground surface, the sample location was adjusted in the field to an area with soil and within 10 feet of the structure.  Cells that fell entirely within an area occupied by a structure and/or asphalt, were eliminated from the number of samples to collect. Based on those criteria, 10 of the 12 grid sample locations were sampled in the field. As previously stated in Section 3.2, the proposed surface soil sample in cell F4 (Figure 2) was eliminated because the ground surface was covered with asphaltic concrete. Surface soil sample location C2 (Figure 2) was also not sampled because the grid fell entirely within an area occupied by the Warehouse building. Field personnel obtained the surface soil samples by hand-excavating shallow test pits from the surface to approximately 0.5 feet below ground surface (bgs). Field personnel logged the lithology encountered in each test pit and also noted any visual or olfactory observations that indicated potential contamination. Following sample collection, field personnel also documented the approximate location of each test pit on a field map and recorded the coordinates of each test pit using a hand-held resource grade global positioning satellite (GPS) unit for placement on geo-referenced report figures. Figure 2 shows the locations of the 10 test pits that were sampled. The hand-excavated test pits were labeled according to their coordinate in the grid system developed for the Site. For example, a test pit completed in the grid square A,1 was labeled according to the Site name (Dumas Seed - “DS”) their corresponding test pit number and sample depth. Therefore, a sample collected from TP-A1 (Figure 2) from the 0- to 0.5-foot depth interval was labeled DSTP-A1(0-0.5’). Surface soil samples obtained from the 10 hand-excavated test pits were placed in laboratory- provided sample containers and transferred immediately to a cooler containing doubled re- sealable bag filled with ice. All samples were handled and shipped under standard chain-of- custody procedures to a NELAP-accredited laboratory for analysis. For this Phase II ESA, the samples were submitted to Eurofins Lancaster Laboratories (Lancaster) in Lancaster, for the parameters listed in the following table.

However, information obtained during the Phase I ESA indicated the gasoline UST was likely located near the Scale House (Figure Construction information obtained for the second UST indicated it was a relatively small tank (approximately 550 gallons), that it was used to store diesel fuel and it included copper piping. Based on this information Tetra Tech concluded that if the UST was located on-site, it may have been used to support an oil-fired heating unit for the Scale House. No pipes, vents or other indications that a UST remains on site was observed during the field investigation. To evaluate whether petroleum hydrocarbon contamination exists in association with the UST(s), the subsurface soil investigation was designed to focus on the area surrounding the Scale House and scales (Figure Tetra Tech subcontracted with a direct-push technology (DPT) drilling subcontractor to obtain soil samples from up to six borings around the perimeter of the Scale House and scales. As previously stated in Section 3.2 of this report, the proposed boring located east of the mid-point of the scales adjacent to North Almon Street was eliminated due to potential buried utilities. The number of proposed DPT borings located around the perimeter of the Scale House and scales area was therefore reduced from six borings to five borings. Figure 2 presents the approximate locations of the DPT borings installed as part of the subsurface soil investigation. Continuous soil samples were obtained from each boring beginning at grade to a maximum depth of 15 feet below ground surface (bgs). Field personnel recorded the lithology, debris, relative moisture, soil color, staining, and odor for the entire depth of the boring. A portion of the soil recovered from each interval was analyzed on-site for volatile organic constituents (VOCs) using a photoionization detector (PID). The remaining portion of each soil sample was temporarily retained in a re-sealable plastic bag in a cooler containing doubled re-sealable bags filled with ice for potential laboratory analysis. Samples were labeled according to the Site name (Dumas Seed - their corresponding DPT boring number (e.g. DPT-1), and sample depth interval. Field personnel documented the approximate location of each DPT boring on a field map and recorded the coordinates of each DPT boring location using a hand-held resource grade global GPS unit for placement on geo- referenced report figures. The soil sample exhibiting the highest PID reading in each boring was submitted for laboratory analysis. In addition, the soil sample collected at the air/groundwater interface was also submitted for laboratory analyses. In the event that field screening did not indicate potential contamination then only the sample obtained from the air/groundwater interface in that boring was submitted to Eurofins Lancaster Laboratories for analysis of the parameters listed in the following table. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 12 SUBSURFACE SOIL INVESTIGATION – SCALE HOUSE AREA ANALYTICAL REQUIREMENTS Media Area Number of Samples Analyses EPA Method Subsurface Soil Scale House / UST 6 Volatile Organic Compounds (VOCs) Ethylene Dibromide (EDB) Polynuclear Aromatic Hydrocarbons (PAHs) Lead 8260B 8011 8270 SIM 6020 3.4.3 Monitoring Well Installation and Groundwater Sampling Tetra Tech installed four groundwater monitoring wells at the Site to evaluate potential impacts from historic use of pesticides (e.g. rodenticides, fumigants, and possibly fungicides) and herbicides, and potential impacts from the former USTs. Figure 2 shows the monitoring well locations. The purpose of each well was as follows:  DSMW-1: Potential background well installed to evaluate water quality upgradient of anticipated on-site impacts and to provide information about potential contribution of contaminants from upgradient sources.  DSMW-2 This well coincided with the location of DPT boring (Figure 2) installed in the Scale House area to evaluate potential impacts from petroleum hydrocarbons from former USTs and pesticide or herbicide application to the eastern portion of Site.  DSMW-3: This well was installed in the central portion of the Site, downgradient of the Mill and adjacent to the former silos to evaluate impacts to groundwater from application of pesticides and herbicides as well as potential upgradient releases of petroleum products from USTs in the area of the Scale House.  DSMW-4: This well was installed near the western site boundary to evaluate water quality in the western portion of the Site and water quality potentially migrating off site. 3.4.3.1 Subsurface Soil Sampling Each well boring was advanced using DPT technology to a maximum depth of 15 feet bgs. Continuous soil samples were obtained as each borehole was advanced to document subsurface soil conditions. Upon reaching the target depth, each boring was re-drilled using a hollow-stem auger (HSA) to excavate soil and expand dimensions of the boring and accommodate well installation. Field personnel recorded the lithology encountered in each boring and recorded debris, relative moisture, soil color, staining, and odor for the entire depth of the boring. A portion of the soil recovered from each interval was analyzed on-site for volatile organic constituents using a PID. The remaining portion of the sample was temporarily retained in a re-sealable plastic bag in a cooler containing doubled re-sealable bags filled with ice for potential laboratory analysis. The soil sample exhibiting the highest PID reading in each boring was submitted for laboratory analysis. In addition, the soil sample collected at the air/groundwater interface was also submitted for laboratory analyses. In the event that field screening did not indicate potential ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 13 contamination then only the sample obtained from the air/groundwater interface in that boring was submitted for laboratory analyses. Soil samples collected during installation of monitoring wells were labeled according to the Site name (Dumas Seed their corresponding well number (e.g. MW-1), sample depth interval of soil collection. Soil samples collected at the air/groundwater interface from each boring was were submitted to Eurofins Lancaster for the parameters listed in the following table.

Factory slotted 0.020-inch (PVC) well screen was incorporated in the lower 10 feet of each well. The sand filter pack around the well screen extended approximately 1 foot above the screened interval. Bentonite chips were added from the top of the filter pack to approximately 1-foot bgs. Each well was completed with a flush- mount well protector cemented in place. Following well installation, field personnel developed each monitoring well using a surge and bail technique to remove fine-grained material and improve communication with the water- bearing strata. In general, wells were developed until a reduction in turbidity was measured using a field turbidity meter. Depth to water measuring points were established on the north side of the top of each monitoring well casing. All monitoring well locations were located using a resource grade hand held GPS unit. The measuring point elevations were surveyed using a portable level and survey rod with well DSMW-1 (Figure 2) designated as an arbitrary local datum. 3.4.3.3 Groundwater Monitoring and Sampling Depth to water was measured in all four wells after water levels were allowed to stabilize and prior to sampling. Groundwater sampling was completed using a peristaltic pump with dedicated disposable tubing and the EPA low-flow purge method. Field personnel recorded pH, specific conductance (SC), oxidation-reduction potential (ORP), dissolved oxygen (DO) and temperature during well purging. Purging was considered completed when field parameters stabilized to ±10%. Water samples collected from each of the four wells were submitted to Eurofins Lancaster for the parameters listed in the following table. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 14 GROUNDWATER SAMPLING ANALYTICAL REQUIREMENTS Media Area Estimated Number of Samples Analyses EPA Method Groundwater Site-Wide 4 VOCs EDB PAHs Herbicides Pesticides/Organochlorine Pesticides Organophosphate Pesticides 8 RCRA Metals + Copper 8260B 8011 8270 SIM 8151 8081 8141 6020/7471 3.5 October 2012 Soil Investigation Methods Preliminary results of the April 2012 investigation indicated widespread distribution of several contaminants of potential concern (COPCs) across surface soil sampled from the 0- to 6-inch depth interval at the Site. Therefore, additional characterization and risk evaluation of site soil was deemed necessary to further evaluate potential risk. 3.5.1 Sample Method Tetra Tech collected surface soil samples over the entire property in October 2012 to characterize the nature, extent, and magnitude of contamination. Field personnel performed lateral and vertical soil sampling in order to characterize potential impacts at the Site by implementing an incremental sampling methodology (ISM). Tetra Tech generally followed the Incremental Sampling Methodology (ISM) described in The Interstate Technology & Regulatory Council (ITRC) Technical and Regulatory Guidance document for Incremental Sampling Methodology (ITRC 2012). The ISM process consists of estimating the mean concentration of contaminants in specified volumes of soil referred to as decision units (DUs). Numerous increments (i.e. subsamples) of soil are collected from areas specified as sampling units (SUs) that are combined into one ISM sample in order to reduce data variability and provide more consistent results compared to discrete sampling methods. Soil samples obtained from the sampling units within the NDU and SDU were collected using decontaminated hand tools such as a shovel, digging bar or similar. Because the soil at the Site was very compact, Tetra Tech also used a mechanical hand auger and an electronic jackhammer to break up the soil to obtain soil samples to the 1-foot depth, and along the former railroad line to the 2-foot depth. Sampling equipment was decontaminated between DUs. For this investigation the Site sampling area consists of three DUs that corresponds with; 1) the warehouse building (north DU; NDU); 2) the mill building (south DU; SDU); and 3) the railroad line (RDU) (Figure A description of the areas follows.  NDU: NDU consists of one SU. The SU includes the soil surrounding the warehouse on all sides. For the southern side of the warehouse that adjoins the railroad line, the ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 15 DU/SU boundary is designated as the area from the warehouse wall to 10 feet south, toward the railroad line area. The remaining soil areas surrounding the warehouse are bound by the property boundary. Field personnel collected one ISM sample from the 0- to 1-foot depth interval from NDU.  SDU: SDU consists of one SU. SDU consists of those areas north, south, east and west of the mill building. For the northern side of the mill that adjoins the railroad line, the DU/SU boundary is designated as the area from the mill wall to 10 feet north, toward the railroad line area. The eastern portion of the SDU is paved with asphalt. Field personnel collected one ISM sample from the 0- to 1-foot depth interval from SDU.  RDU: RDU consists of two SUs; an east SU and a west SU. RDU runs the length of the property between NDU and SDU. Fill has been brought to the property during demolition work due to wet conditions and placed within the former railroad grade area. The fill was placed over top the former railroad grade area and may have been mixed with the former railroad grade materials. Therefore, the purpose of the sampling was to characterize these materials and particularly the railroad grade materials that may have been buried by the fill, and provide data for possible volume calculations during remedial alternatives evaluations. Field personnel collected two ISM samples from each railroad SU. One soil sample was collected from the 0- to 1-foot depth interval in each SU and a second sample was collected from the 1- to 2-foot depth interval in each SU for a total of four samples. Figure 1 shows the sample locations for each DU/SU. Tetra Tech developed sampling points using GIS. The points were generated randomly using a grid system. Tetra Tech used a GPS unit in the field to locate the sample locations. Of note, the mill and warehouse structures were omitted from the random sample generation because sampling beneath the flooring was not possible during the sampling event. Tetra Tech could not gain access to soil beneath the flooring to evaluate potential COPCs in crawlspaces, access-ways or conveyor runs during the October 2012 site investigation. 3.5.2 Soil Analyses Samples were labeled to include the site name (Dumas Seed Site; Since the NDU and SDU decision units are each comprised of one sampling unit, the sample designations will include the DU name and the sample interval. As an example, the ISM sample obtained from north decision unit (NDU) at the 0 to 1-foot soil depth interval will be labeled as follows: DSS-NDU(0-1’). The RDU was divided into 2 sampling units; RSUW (west sampling unit) and RSUE (east sampling unit. The samples obtained from RDU will identify the site name, the sampling unit and the sample interval. As an example, the sample obtained from the west sampling unit of RDU at the 0 to 1-foot soil depth interval will be labeled as follows: DSS-RSUW(0-1’). In accordance with the SAP (Tetra Tech, 2012b and 2012c), soil samples were analyzed for the following parameters. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 16 SURFACE SOIL INVESTIGATION Media Number of Sampling Units (SU) Total Number of Soil Samples Number of QA/QC Samples Total Anticipated Number of Samples Collected for Analysis Analytical Parameter EPA Method Soil 4 6* 9 Herbicides Pesticides/Organochlorine Pesticides Pesticides 8 RCRA Metals + Copper 8151 8081 8141 6020/7471 *NDU – 1 soil sample from 0- to 1-foot; SDU – 1 soil sample from 0- to 1-foot; RDU – 2 soil samples from 0- to 1-foot (east and west SUs) and 2 soil samples from the 1- to 2-foot (east and west SUs). 1 soil duplicate, 1 soil triplicate, 1 rinsate blank 3.6 Quality Assurance/Quality Control Sample Requirements Field personnel collected QA/QC samples during the April and October 2012 investigations to evaluate precision, accuracy, representativeness, completeness, and comparability. A total of four QC samples were collected for this project. The following table presents the number and type of QC samples that were collected.

However, the trip blank was inadvertently not included in the sample set shipped to the laboratory for analysis. In addition to the above, the analytical laboratory analyzed laboratory control samples, method blanks, matrix spike/matrix spike duplicates, and other QA/QC analyses to ensure data quality. 3.7 Waste Disposal Soil cuttings generated during drilling of DPT boreholes and installation of groundwater monitoring wells was containerized and temporarily staged on-site in a 55-gallon drum. The drum was labeled as to its contents, project, and date. The soil cuttings will remain on-site until soil analytical results have been evaluated. If analytical results indicate the cuttings do not exceed soil remedial action levels, they will be thin spread on-site. Soil cuttings that exceed remedial action levels will remain on-site until waste disposal options can be evaluated and funding for disposal allocated for the soil. Soil removed from the shallow hand-excavated test pits was replaced in the excavation. Purge water generated during monitoring well development and sampling was thin-spread in the general vicinity of the well that was sampled. 3.8 Risk Analyses Tetra Tech conducted a numerical risk evaluation using modeling software provided by the IDEQ and Risk Evaluation Manual (REM). The original risk analyses performed by Tetra Tech on the April 2012 data indicated risk that exceeded the maximum cumulative risk value of 1x10- 5, which indicated soil at the Site posed an unacceptable risk to residential receptors. Based on the April 2012 risk assessment results, IDEQ and the City of Moscow requested further evaluation of the Site as per the ISM method, which would allow for better characterization of soil across the Site. The risk assessment results presented herein are based on the October 2012 ISM sample results. This risk assessment incorporates applicable subsurface soil and groundwater data from the April 2012 investigation. User inputs into the IDEQ risk model include contaminant concentrations and the potentially completed exposure pathways. The model includes default values for various parameters but ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 18 can use site specific data if sufficient justification for modifying the parameters can be provided. General model setup and model running follows the below steps: 1. Identify receptors and pathways (e.g. residential, non-residential and construction worker receptors, soil and groundwater pathways, etc.); 2. Enter representative contaminant concentrations and site-specific parameters; 3. Software generates a cumulative risk and hazard index values for each receptor and exposure pathway; and 4. Software generates RATL-1 values which then may be used as cleanup levels in a cleanup plan to remediate the site. The risk evaluation model determines whether the concentrations of the COPCs pose a risk to human health or the environment and develops remedial action target levels (RATLs) for each COPC in each media identified in the exposure pathway and for each potential receptor. In order to be most protective of human health, the lowest RATL generated by the risk evaluation for each COPC generated was chosen to compare with COPC concentrations in each media. A discussion of the information used to conduct the risk evaluation is presented below. 3.8.1 Exposure Assessment For purposes of completing the exposure assessment, Tetra Tech assumed future development of the property may include construction work, and use as single family or multi-family housing. Therefore, exposure assessment assumed potential receptors consisted of residential and non- residential receptors as well as construction workers. Routes of exposure by media consisted of surficial soil, subsurface soil, and groundwater. In addition, the Site is bounded to the west by the Hogg Creek stream channel. For that reason the default value of zero was selected as the distance to surface water. 3.8.2 Contaminant Concentrations Representative concentrations of COPCs in surface soil, subsurface soil and groundwater were determined using guidance provided in the IDEQ’s Risk Evaluation Manual (REM). For this evaluation the highest concentration for each analyte detected above the laboratory practical quantitation limit (PQL) in the affected media was used as this would generate results considered the most protective of human health and the environment. Again, the surface soil data used for the risk assessment presented herein were obtained from the October 2012 results while the subsurface soil and groundwater results were obtained from the April 2012 investigation results. A list of the COPCs and their maximum concentrations is included in the IDEQ Input Forms 3.8.3 Exposure Factors The exposure factors quantify the parameters through which receptors are potentially exposed to COPCs at a site. The default exposure factors in IDEQ’s REM software were used for the risk calculation. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 19 3.8.4 Fate and Transport Parameters Fate and transport factors quantify site-specific parameters including the separation between the soil and groundwater sources and the foundation of any building at the Site. The current understanding for the Site is that the existing structures will be removed. However, information including the type, size and locations of future structures has not yet been determined. For this evaluation, the default values for fate and transport parameters were used in the risk calculation. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 20 4.0 PHASE II ESA INVESTIGATION RESULTS The following sections present a discussion of the data validation conducted by the analytical laboratory and Tetra Tech, analytical results of soil and groundwater samples obtained as part of this Phase II ESA, and results of the risk analysis. Referenced figures and tables are presented in Appendices A and B, respectively. Laboratory analytical data reports for soil and groundwater samples obtained during this investigation are contained in Appendix C. Appendix D presents copies of field logs completed during installation of soil borings and groundwater sampling. Copies of IDEQ risk evaluation software output sheets are contained in Appendix E. 4.1 Data Evaluation Soil and water samples for this project were submitted to Eurofins Lancaster Laboratories in Lancaster, for analysis. Tetra Tech completed an evaluation of the analytical laboratory reports for this project using EPA CLP National Functional Guidelines to direct qualification of data. Additional details regarding data evaluation are included in the Master QAPP (TerraGraphics 2011). The following sections provide a summary of data evaluation with respect to the field and laboratory QA/QC data. A quality control summary provided by the laboratory is included in the laboratory analytical reports in Appendix C. 4.1.1 April 2012 Analytical Data 4.1.1.1 Laboratory Quality Control Samples Soil A review of the laboratory evaluation of soil sample QA data indicates the following compounds were outside the specified limits in the matrix quality control sample:  Carbon disulfide  Gamma BHC – Lindane (132%);   Endrin  Chromium (149%); and,  Copper(154%). Discussions with the analytical laboratory representative indicated that these results were a consequence of matrix issues and not an analysis issue and therefore, did not affect the quality of the data. The analyst stated that according to the analytical methods, no qualification of the data was required. In addition, several compounds were detected in soil samples at concentrations equal to or greater than the analytical method detection limit (MDL) but less than the analytical method limit of quantitation (LOQ). Those concentrations were qualified by the laboratory with a indicating the value is estimated. Water A review of the laboratory evaluation of water sample data indicates the following compounds were outside the specified limits in the matrix quality control sample: ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 21  Acenaphthene (115%);  (117%);  Fluoranthene (111%); and,  Pyrene (121%). Discussions with the analytical laboratory representative indicated that the analytical results would be biased as high for those compounds but since none of those compounds were detected in the natural samples, no qualification of the data was required. The analytical report also noted the relative percent difference between the laboratory control sample (LCS) and the laboratory control sample duplicate (LCSD) was outside of the acceptable range. Because the recovery of both the LCS and the LCSD was within the acceptable range of values no flagging of the data was required. In addition, several compounds were detected in water at concentrations equal to or greater than the analytical MDL but less than the analytical method LOQ. Those concentrations were flagged by the laboratory with a indicating the value is estimated. 4.1.1.2 Field Quality Control Samples Field Duplicate One field duplicate groundwater sample was obtained from well MW-3 during the April 2012 monitoring event. Recoveries for all of the constituents detected in the natural and duplicate sample were within acceptable criteria. No qualification of the data was required. Equipment Rinsate Blank One equipment rinsate blank was collected by field personnel during this investigation and exhibited concentrations of arsenic, cadmium, copper and mercury that were greater than the MDL but less than the LOQ. The results were qualified as estimated, Field Blank The field blank prepared by field personnel and submitted for laboratory analyses did not exhibit detectable concentrations of analytes. Therefore, no qualification of the analytical data was warranted. Trip Blank In accordance with the project SAP, one trip blank prepared by the laboratory was to be submitted for laboratory analyses of VOCs using EPA method 8260B. Due to a shipping error the trip blank was not provided to the laboratory for analyses. No qualification was warranted. 4.1.2 October 2012 Analytical Data 4.1.2.1 Laboratory Quality Control Calibration The laboratory noted that the identification of delta-BHC and heptachlor was reversed in the calibration and samples. As a result, the QC recoveries for those compounds required modification on the QC summary and results. The laboratory summary page presents details of the require modifications. The corrected laboratory report is presented in Appendix C. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 22 Matrix Spike/Matrix Spike Duplicates, and Laboratory Duplicates Several pesticide constituents analyzed via Method 8141 were outside the upper control limits, which could result in potentially biased high results. However, the corresponding pesticide results in the field samples were not detected at or above the laboratory PQL. Therefore, no qualification was required. The relative percent difference for the matrix spike/matrix spike duplicate for the herbicide MCPA was outside the 50% control limit. No qualification was required none of the results for MCPA were detected at or above the laboratory PQL. The matrix spike recoveries for ethoprop, mevinphos, and naled were above the upper control limit. These constituents were not detected in any of the samples analyzed; therefore, no qualification was necessary. The matrix spike recoveries for dieldrin, p,p-DDD, delta BHC, and were outside control limits. Associated samples greater than the PQL were qualified as estimated, Results for dieldrin were qualified as estimated due to recoveries and RPDs outside control limits. Several metals, including arsenic, barium, copper, and lead exhibited matrix spike recoveries and/or RPDs outside control limits. However, a second set of matrix spike and matrix spike duplicate samples were analyzed and all results were within control limits and laboratory duplicate RPDs were within control limits. No qualifications were made. The laboratory duplicate for endrin aldehyde was outside control limits. Associated samples greater than the PQL were qualified as estimate, 4.1.2.2 Field Quality Control Equipment Blank One equipment rinsate blank was collected by field personnel during this investigation. No constituents were detected at or above the laboratory PQL. Duplicate and Triplicate Results The RPDs for the duplicate and triplicate results were calculated to evaluate variability in the samples. Metal RPDs between the natural sample (DSS-RSUW and the duplicate sample were within the 50% control limit with the exception of the results for lead and mercury which had 78.6% and 55.6% RPDs, respectively. RPDs between the natural sample and the triplicate were outside the 50% RPD control limit with the exception of the RPDs for chromium, copper, and lead. The RPDs between the duplicate and triplicate samples were within the 50% RPD with the exception of the RPDs for barium, and silver. All metals results for the project, with the exception of results for chromium and copper, were qualified as estimated, due to RPDs above 50% for one or more sample pairing being outside control limits. One or more pesticide RPD results for gamma chlordane, p,p-DDE, p,p-DDT, and dieldrin were outside the 50% RPD control limit. Results for these compounds were qualified as estimated, ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 23 Of note, when the duplicate and triplicate soil samples were received by the laboratory, laboratory personnel logged these samples in for use as matrix spike/matrix spike duplicate samples, rather than for analysis as field duplicate and triplicate samples. Therefore, the initial data set received from the laboratory did not include results for these samples and only presented results as matrix spike/matrix spike duplicates. Tetra Tech subsequently requested that the laboratory log the samples in as field samples and analyze as originally requested. The laboratory initially had only extracted the amount of sample required to run the matrix spike/matrix spike duplicate samples. Hence, there was no extracted sample remaining but there was soil remaining in the initial sample containers. Therefore, extracting and analyzing the field duplicate and triplicate samples were outside of specified holding times for organic compounds. Because the results were analyzed outside of holding times, positive results for organic constituents for these samples were qualified as estimated, 4.2 April 2012 Soil and Groundwater Sample Results The following section presents a discussion of field and laboratory analytical results of soil and groundwater samples obtained in April 2012 during this Phase II ESA investigation. 4.2.1 Site-Wide Surface Soil Samples Surface soil encountered in the hand-excavated test pits consisted predominantly of dark brown to gray to black sandy silt with gravel. None of the surface soil samples exhibited visual or olfactory indications of contaminants. The surface soil samples were generally moist to wet which was likely the result of recent precipitation events that occurred in the Moscow area during the days prior to the field investigation. Table 1 presents the surface soil analytical results. Figure 2 shows the location of the surface soil samples. A review of those data indicates that arsenic lead, mercury, selenium and silver exceeded the IDTLs and RATL-1s in the majority of the surface soil samples. In addition, several pesticides including Alpha BHC, Beta BHC, Gamma BHC-lindane, and Dieldrin were detected in several soil samples at concentrations also exceeding their respective IDTLs and RATL-1s. The distribution of subsurface soil sample locations that exhibited concentrations of COCs exceeding IDTLs and RATL-1s were widespread and not located in one centralized portion of the site. This may indicate either wide spread usage and/or redistribution of contaminants through site activities. Based on these results and in consultation with the City of Moscow and the IDEQ, it was determined that a supplemental investigation of surface soil at the site was warranted in order to further evaluate the risk that the COCs in subsurface soil posed to potential receptors. Results of a supplemental investigation completed at the site in October 2012 and the subsequent risk assessment are presented in Section 4.3 and Section 4.4, respectively, of this report. 4.2.2 Scale House Subsurface Soil Samples Beneath the paved surface, the lithology encountered in the DPT borings generally consisted of sandy gravel fill ranging from 0.25 to 0.5 feet thick underlain by varying thicknesses of silt, silty gravel and silty sandy gravel. Immediately beneath the fill in boring (Figure 2) was a 0.3 foot thick layer of concrete underlain by an additional layer of fill that exhibited woody debris. Beneath the second fill layer in were the silt and silty gravel layers consistent with ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 24 those encountered in the other DPT borings. Subsurface soil encountered in cores from the borings appeared dry to moist at depths less than approximately 13 feet below grade, below which soil samples were saturated. No visual or olfactory indications of petroleum hydrocarbons were observed in soil samples obtained from any of the borings. Headspace field screening for volatile organic constituents did not exceed 0.8 parts per million and therefore, did not indicate the presence of petroleum hydrocarbon impacts. Table 2 summarizes laboratory analytical results of subsurface soil samples obtained from the DPT borings installed near the Scale House. The following is based on a review of that data:  Lead: Lead was detected above the IDTL and RATL-1 in the sample collected from the 0.5- to 5-foot depth interval in boring No other soil samples obtained from the DPT borings exhibited lead concentrations at or above the IDTL or RATL-1.  Acetone: Acetone was detected in the subsurface soil samples collected from the 13- to 15-foot depth interval in DSPT-3 and However, the concentrations were below the IDTL and RATL-1.  Benzene: Benzene was detected in the subsurface soil sample collected from the 10- to 13- foot depth interval in boring and in the subsurface soil sample collected from the 13- to 14-foot depth interval in boring Both concentrations were less than IDTL and RATL-1.  Carbon Disulfide: Carbon disulfide was detected in the subsurface soil sample collected from the 10- to 13-foot depth interval in The concentration of carbon disulfide was below the IDTL and RATL-1.  Semi-volatile organic compounds (SVOC): Several SVOC compounds were detected in the subsurface soil sample collected from the 0.5- to 5-foot depth interval in boring However, the concentrations of SVOCs in the sample were less than their respective IDTLs and RATL-1s. Soil samples obtained from borings installed in the vicinity of the Scale House and scales did not exhibit concentrations of petroleum hydrocarbons indicating significant releases of petroleum hydrocarbons from the former USTs. With the exception of lead, no other COCs exceeded regulatory standards. 4.2.3 Monitoring Well Installation and Sampling 4.2.3.1 Subsurface Soil Sample Results The lithology encountered in the borings completed as groundwater monitoring wells generally consisted of varying thicknesses of silt, silty gravel and silty sandy gravel. Soil samples obtained from the borings completed as monitoring wells were generally dry to moist at depths less than approximately 13 feet below grade. The air-water interface was encountered at approximately 13 feet below grade. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 25 Table 3 summarizes laboratory analytical results of the five soil samples obtained from the borings completed as monitoring wells. Figure 2 shows the well locations. The following is based on a review of that data:  Arsenic: All arsenic concentrations in subsurface soil samples collected from the borings exceeded the IDTL and/or RATL-1.  Mercury: The subsurface soil sample collected from the 5- to 10-foot depth interval in boring DSMW-1 exhibited concentrations of mercury above the IDTL and RATL-1. Mercury concentrations in the remaining soil samples were either below the analytical reporting limit or below the IDTL and RATL-1.  VOCs: Acetone, benzene, 2-butanone and carbon disulfide were detected in several of the subsurface soil samples collected from the borings. However, concentrations for each of those compounds were less than their respective IDTLs and RATL-1s.  Pesticides: The subsurface soil sample collected from the 1- to 14-foot depth interval in boring DSMW-4 exhibited Endrin ketone at 0.001 mg/kg. There is not an established IDTL for Endrin ketone in soil. No other soil samples obtained from the well borings exhibited herbicides or pesticides Subsurface soil samples obtained while drilling the monitoring wells exhibited arsenic and mercury above regulatory standards. VOC constituents were also detected in several soil samples; however, concentrations were only above the analytical method detection limit and did not exceed regulatory standards. 4.2.3.2 Groundwater Analytical Results Appendix D provides the groundwater sample logs for samples obtained during the April 2012 monitoring event. Table 4 summarizes the groundwater laboratory analytical results. Figure 2 presents the location of the four monitoring wells (DSMW-1 through DSMW-4). A review of the data indicates the following:  Depth to water measured in the four monitoring wells during the April 2012 monitoring event ranged from 1.35 feet below the measuring point in well DSMW-4 to 3.56 feet below the measuring point in well DSMW-2. Groundwater contours could not be developed and interpreted due to the variability in groundwater elevations across the site.  Groundwater samples obtained from each of the four monitoring exhibited detectable concentrations of several RCRA metals; however all were less than the corresponding IDTLs and RATL-1s.  None of the groundwater samples exhibited detectable concentrations of the lead scavenger Ethylene dibromide (EDB) or VOCs.  Naphthalene was detected in the groundwater samples obtained from wells DSMW-1, DSMW-2 and DSMW-4; however, at concentrations only above the analytical method detection limit of 0.0001 microgram per liter (µg/L). The corresponding IDTL and RATL-1 for naphthalene in groundwater is 209 µg/L. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 26  The water samples from wells DSMW-1 and DSMW-2 exhibited the herbicide Dalapon at estimated concentrations of 0.0013 µg/L and 0.69 µg/L, respectively. The IDTL and RATL-1 for Dalapon is 200 µg/L.  The groundwater sample from well DSMW-4 exhibited a Beta BHC concentration of 0.0000047 µg/L, which is well below the corresponding IDTL and RATL-1 (0.031 µg/L). Groundwater elevations above the screened interval in each monitoring well are likely indicative of either confined or semi-confined conditions. As stated in Section 4.2.3, soil samples obtained from borings completed as groundwater monitoring wells at depths shallower than approximately 13 feet below grade did not exhibit indications of yielding water. Additional monitoring would be required to evaluate seasonal fluctuations in groundwater elevations and flow, if any. None of the groundwater samples obtained during the April 2012 monitoring exhibited COCs exceeding regulatory standards. 4.3 October 2012 Soil Investigation Results The following section presents a discussion of field and laboratory analytical results of ISM soil samples obtained in October 2012 during this Phase II ESA investigation. Soil encountered in the hand-excavated test pits were generally consistent with those observed in the April 2012 investigation test pits and described in Section 4.2.1. None of the soil samples exhibited visual or olfactory indications of contaminants. Tables 5A, 5B and 5C present analytical results of ISM samples obtained from RDU, NDU and SDU, respectively. The RATL-1 values reported in those tables were generated using exposure pathways which included residential (child and age-adjusted) receptors as further described in Section 4.4 of this report. Figure 3 shows the locations of the ISM soil samples. A review of those data indicates the following: RDU (Table 5A):  The ISM surface soil samples [DES-RSUW DES-RSUE DUPLICATE and TRIPLICATE], exhibited concentrations of arsenic exceeding the corresponding IDTLs. Arsenic concentrations in surface soil samples DES-RSUW DES- RSUE DUPLICATE and TRIPLICATE exceeded the RATL-1 (0.279 milligrams per kilogram (mg/kg)) but were less than the background soil concentration established for the Spokane, Washington area (15 mg/kg; WDOE 1994).  The lead concentration in the DES-RSUE surface soil sample exceeded the RATL-1 (49.6 mg/kg) but was less than the EPA RSL cleanup level for lead in residential soil (400 mg/kg).  The mercury concentrations in surface soil samples DES-RSUW DES-RSUE DUPLICATE and TRIPLICATE exceeded the IDTL (0.00509 mg/kg) but were less than the RATL-1 value (1.81 mg/kg) generated using the IDEQ software. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 27  The selenium concentration in the DES-RSUW sample exceeded the IDTL (2.03 mg/kg) but was less than the RATL-1 for residential soil (23.8 mg/kg) generated using the IDEQ software.  Pesticides were detected in several surface soil samples obtain from the RDU. Of those pesticides that exceeded corresponding IDTLs, none exceeded their corresponding RATL-1 for residential soil generated using the IDEQ software. In summary, arsenic detected in the subsurface soil samples obtained from DSS-RSUW and DSS-RSUE, exceeded the IDTL and RATL-1. Arsenic concentrations in those two samples were less than the 15 mg/kg background soil concentration established for the Spokane, Washington area (WDOE 1994). No other constituents exceeded their respective RATL-1s. NDU (Table 5B):  ISM surface soil sample DSS-NDU exhibited concentrations of arsenic and mercury exceeding the corresponding IDTLs of 0.391 milligrams mg/kg and 0.00509 mg/kg, respectively. The arsenic concentration in that sample also exceeded the RATL-1 (0.781 mg/kg) generated using the IDEQ software but was less than the background soil concentration established for the Spokane, Washington area (15 mg/kg; WDOE 1994).  DSS-NDU exhibited detectable concentrations of several pesticides; however, only the concentration of dieldrin exceeds the IDTL and RATL-1. SDU (Table 5C):  ISM surface soil sample DSS-SDU exhibited concentrations of arsenic, mercury and selenium exceeding the corresponding IDTLs of 0.391 milligrams mg/kg, 0.00509 mg/kg and 2.03 mg/kg, respectively. The arsenic concentration in that sample also exceeded the RATL-1 (0.558 mg/kg) generated using the IDEQ software but was less than the background soil concentration established for the Spokane, Washington area (15 mg/kg; WDOE 1994).  DSS-SDU exhibited detectable concentrations of several pesticides. The concentration of dieldrin exceeded the IDTL but was less than the RATL-1 generated using the IDEQ software. No other pesticides exceeded IDTLs or RATL-1s. Arsenic and lead were the predominant metals detected in the surface soil samples obtained from the three decision units that exceeded IDTLs and RATL-1 values. However, none of the concentrations of arsenic and lead exceeded the cleanup level for arsenic in the Spokane, Washington area or the lead cleanup value established for EPA RSL cleanup level for residential soil (EPA 2012). All of the surface soil and subsurface soil samples exhibited detectable concentrations of several pesticides indicating widespread usage or redistribution through site activities. However, only the dieldrin concentration detected in the northern DU (NDU) exceeded the RATL-1. Section 4.4 discusses the results further in relation to the risk assessment analysis performed for the Site. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 28 4.4 Risk Analysis 4.4.1 IDEQ REM Risk Evaluation Under IDEQ’s risk evaluation program, additional assessment or remediation is required if the risk exceeds 1X10-5 or the hazard index exceeds 1. The maximum concentrations of each individual COPC detected in the various media were used in these calculations as they would be the most conservative and most protective of human health and the environment. Subsurface soil and groundwater results from the April 2012 investigation were used for the October 2012 risk evaluation; while the ISM results for October 2012 were used for surface soil. When the model was run for each decision unit, the IDEQ risk evaluation software indicated soil at the Site presents an unacceptable risks to both child and age-adjusted residential receptors in both the north DU (NDU) and the railroad DU (RDU). The majority of the risk is shown to be from the surface soil route of exposure. Furthermore, when reviewing the risk calculated for each of the COPCs present in subsurface soil, the software indicated the majority of the risk is derived from exposure to arsenic. The risk to receptors in the south DU (SDU), and the hazard indices for all receptors within each of the three DUs, was less than the maximum value of 1. The RE-1 Summary of Risk and Hazard Index forms generated by the risk evaluation software for each of the three decision units are presented below. Appendix E presents the model output forms for each of the three decision units. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 29 4.4.2 Supplemental Dieldrin Evaluation Additional risk evaluation was performed by IDEQ on dieldrin to further assess risk at the Site. The above risk analyses for dieldrin used the maximum of individual sample concentrations and resulted in an unacceptable risk, even when arsenic risk was removed from evaluation during running of the REM program. The ITRC guidance document suggests applying a statistical treatment and presents some decision-making recommendations. The following process was used to perform the supplemental dieldrin evaluation:  For direct contact, the EPA residential RSL for dieldrin is 0.03 mg/kg which has a risk of 1E-6. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 30  With an acceptable cumulative risk of 1E-5 (if dieldrin was allowed, by itself, to account for half of the 5E-6 risk then an adjusted residential action level for dieldrin for direct contact as the main route of exposure would be 5 times 0.03 or 0.15 mg/kg.  Concentration variability can be assessed by using the results of the triplicate sampling performed for sampling unit RSUW. From this variability, both a mean and standard deviation of 0.03 mg/kg is high. A similar variability was reflected in the April 2012 discrete surface samples collected within the NDU area where samples from around the building ranged from 0.0029 to 0.53 mg/kg for dieldrin. Because variability in concentrations between samples is high, the ISM guidance suggests “hot spots” are present.  A 95% Upper Confidence Limit (UCL) estimate of the mean from the replicate RSUW ISM October 2012 data yields 0.11 mg/kg (3.67 times the average), which is still below the action level of 0.15 mg/kg.  Since the other decision units only had one sample and, based on the above assessment, there are indications about the variability of the concentration estimates of dieldrin, this information can be applied to other dieldrin values at the Site to evaluate variability to better reflect site conditions. Assuming a similar amount of variability in the other decision units as those to RSUW, adjusted concentrations for dieldrin based on the 95% UCL would be as follows: o NDU: 0.1 mg/kg dieldrin * 3.67 = 0.37 mg/kg o RSUE: 0.0247 * 3.67 = 0.09 mg/kg o SDU: 0.0084 * 3.67 = 0.03 mg/kg Based on this evaluation dieldrin in area NDU (pre-building removal) exceeds the action level; in fact it would exceed an action level based on all the risk being due to it (0.3 mg/kg) and no other chemicals. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 31 5.0 SUMMARY AND RECOMMENDATIONS The Phase II ESA and risk evaluation at the Site identified concentrations of several COCs in surface and subsurface soil that exceed regulatory standards. Surface soil exhibited the highest concentrations of COCs at the Site. Based on the analytical data obtained during the April and October 2012 site investigations, concentrations of most of the metals detected in the surface soil samples decreased with depth. Pesticide and herbicide impacts also appeared to be predominantly limited to surface soil across the Site indicating either wide-spread application or redistribution through site activities. The initial site investigation completed in April 2012 indicated wide-spread metals and pesticides in surface soil at the Site. Lead in subsurface soil exceeded the RATL-1. There were no exceedences of COPCs in groundwater. Based on the initial risk evaluation, a follow-up investigation and risk evaluation was performed to better understand concentrations of COPCs in soil at the Site. A summary of the October 2012 investigation and risk evaluation is as follows.  Arsenic and dieldrin exceeded their respective IDTLs and RATL-1s for the NDU; arsenic, and lead exceeded their respective IDTLs and RATL-1s for the RDU; and arsenic exceeded the IDTL and RATL-1 for the SDU. None of the arsenic concentrations in the three decision units exceeded the soil cleanup level of 15 mg/kg for the Spokane, Washington area; and none of the lead concentrations exceeded the EPA RSL of 400 mg/kg (EPA 2012).  The risk exceedance in the NDU and RDU appeared predominantly due to arsenic concentrations detected in surface soil as the values generated by the model were much higher than the other constituents.  The risk evaluation completed by Tetra Tech indicated an unacceptable cumulative risk in surface soil to both child and age-adjusted residential receptors in the north decision unit (NDU; former warehouse area) and the railroad decisions unit (RDU; the former railroad right-of-way). The supplemental evaluation by DEQ for dieldrin resulted in a 95% UCL estimate of 0.11 mg/kg (3.67 times the average dieldrin concentration) for the October 2012 data. The 95% UCL value for RDU is below the adjusted action level of 0.15 mg/kg (5 times the EPA RSL of 0.03 mg/kg). However, the supplemental evaluation produced adjusted dieldrin soil concentrations for the NDU that remain above the adjusted action level of 0.15 mg/kg. As stated above, the risk evaluation indicated surface soil in the two decision units poses an unacceptable cumulative risk to child and age-adjusted residential receptors and arsenic appeared to be the greatest contributor to that risk. However, arsenic concentrations do not exceed the 15 mg/kg cleanup level established for the Spokane, Washington area (WDOE 1994). Based on RATL-1s results, cleanup action for dieldrin is necessary to achieve residential levels for soil in the NDU and RDU. If the adjusted dieldrin action level is approved by IDEQ, based on the supplemental evaluation, cleanup of the RDU may not be necessary but cleanup for the NDU would still be necessary to meet residential levels. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 32 As an alternative, if the site owners determine that residential use of the Site was not part of the redevelopment strategy and thereby eliminate those potential receptors, remedial activities may not be required but additional measures may be needed to eliminate future residential redevelopment without first performing site remediation. For example, to ensure that the Site remains free of residential redevelopment over the long term an institutional control may be required, as described by IDEQ REM (IDEQ 2004) as an Equitable Servitude and Conservation Easement (Servitude). The Servitude is a written agreement that is recorded in County records and whose purpose is to limit use of the Site and prevent activities that may disturb the impacted soil and/or provide an exposure pathway to receptors. ---PAGE BREAK--- Final Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech April 17, 2013 33 6.0 REFERENCES Alt, David D. and Donald 1989.

Surrogate Quality Control Limits: 52-141 40-144 ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- ---PAGE BREAK--- Explanation of Symbols and Abbreviations The following defines common symbols and abbreviations used in reporting technical data: RL Reporting Limit BMQL Below Minimum Quantitation Level N.D. none detected MPN Most Probable Number TNTC Too Numerous To Count CP Units cobalt-chloroplatinate units IU International Units NTU nephelometric turbidity units umhos/cm micromhos/cm ng nanogram(s) C degrees Celsius F degrees Fahrenheit meq milliequivalents lb. pound(s) g gram(s) kg kilogram(s) µg microgram(s) mg milligram(s) mL milliliter(s) L liter(s) m3 cubic meter(s) µL microliter(s) pg/L picogram/liter < less than - The number following the sign is the limit of quantitation, the smallest amount of analyte which can be reliably determined using this specific test. > greater than ppm parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg), or one gram per million grams. For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of gas per liter of gas. ppb parts per billion Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight basis concentration to approximate the value present in a similar sample without moisture. All other results are reported on an as-received basis. Data Qualifiers: C – result confirmed by reanalysis. J - estimated value – The result is ≥ the Method Detection Limit (MDL) and < the Limit of Quantitation (LOQ). U.S. EPA CLP Data Qualifiers: Organic Qualifiers Inorganic Qualifiers A TIC is a possible aldol-condensation product B Value is 25% * Duplicate analysis not within control limits U Compound was not detected + Correlation coefficient for MSA <0.995 X,Y,Z Defined in case narrative Analytical test results meet all requirements of NELAC unless otherwise noted under the individual analysis. Measurement uncertainty values, as applicable, are available upon request. Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be meaningless.

For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of gas per liter of gas. ppb parts per billion Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight basis concentration to approximate the value present in a similar sample without moisture. All other results are reported on an as-received basis. Data Qualifiers: C – result confirmed by reanalysis. J - estimated value – The result is ≥ the Method Detection Limit (MDL) and < the Limit of Quantitation (LOQ).

For aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter of gas per liter of gas. ppb parts per billion Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight basis concentration to approximate the value present in a similar sample without moisture. All other results are reported on an as-received basis.

Surface Water Protection If a surface water body is impacted or threatened, complete the following: If Ammonia is a potential COC for surface water, complete the following: Surface water supports warm water aquatic species? Surface water is used for drinking/water quality is appropriate for drinking water supplies? Surface water supports aquatic life? Surface water is used for recreational activities? Surface water supports cold water aquatic species? Groundwater with Low Probability of Future Use as Drinking Water: Groundwater concentrations protective of off-site receptors resulting from exposure via pathways other than direct ingestion. These pathways include but are not limited to volatilization to indoor air, irrigation water use with crop uptake and ingestion, and irrigation water use without crop uptake.
