(Tetra Tech) completed a Phase II Environmental Site Assessment (ESA) of the 317 West 6th Street (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 Strata (Strata, 2008) and summarized in Section 1.2.3 of this report identified recognized environmental conditions (RECs) from historical use of the Site. The Phase II ESA was completed in general accordance with a site-specific Quality Assurance Project Plan (QAPP) prepared by TerraGraphics Environmental Engineering, Inc. (TerraGraphics) (TerraGraphics, 2012) to guide the investigation. 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 includes the property at 217 and 317 West 6th Street in Moscow, Latah County, Idaho (Figure 1, Appendix A) but is collectively referred to as 317 West 6th Street. The subject property is located on the southwest corner of 6th and Jackson Streets. The subject property is located between Moscow’s historic downtown district and the University of Idaho Campus and had been occupied by industrial agricultural businesses which were supported by the former railroad corridor. More recently a retail produce business occupied a portion of the Site in the 2000s but all of the Site buildings have since been torn down. 1.2 Previous Investigations Tetra Tech reviewed a copy of a previous Phase I ESA conducted for the Site by Strata in 2008 (Strata, 2008). Prior to purchasing the Site, the City of Moscow contracted with Strata to conduct a second Phase I ESA. Results of those investigations identified former bulk storage of agricultural chemicals as a REC for the Site. The Phase I ESAs also identified a small heating oil underground storage tank (UST) at the Site, which was also considered a REC (TerraGraphics, 2011). 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. Paradise Creek appears to be the nearest surface water body and is located approximately 780 feet southwest of the Site. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 2 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 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. Based on information provided in the Phase I ESA (Strata 2008), groundwater flow direction for the Site and site vicinity is anticipated to be in a westerly direction. 1.5 Purpose of Project The City of Moscow was awarded a U.S. Environmental Protection Agency (EPA) Brownfield Assessment Grant in August 2010 to perform assessments on properties with real or perceived contamination in the Moscow, Idaho area. The 317 West 6th Street 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 storage facility for agricultural chemicals. 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 bulk storage facility for agricultural chemicals. 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 has one UST near the eastern boundary that was reportedly contained heating oil to heat the small structure formerly located on the corner of 6th and Jackson. Based on information obtained during the Phase I ESA, the following is a list of contaminants of potential concern (COPCs) for the Site. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 3 CONTAMINANTS OF POTENTIAL CONCERN Contaminant Origin Metal-based pesticides, organochlorine pesticides, organophosphate pesticides, herbicides Pesticide and herbicides storage and application in and around site structures Metals Metals-based pesticides storage and application in and around site structures.

The scope of work for this project consisted of the tasks presented below.  Site Wide Surface Soil: Perform surface soil investigation dividing the Site into three decision units (DUs) as follows: 1) DU1 includes the eastern site office and parking areas; 2) DU2 includes the central bulk agricultural chemical storage area and railroad spur; and 3) DU3 includes the western site warehouse and staging area.  Heating Oil UST: Remove the UST and collect soil samples from the UST excavation area following removal to evaluate potential petroleum hydrocarbon contamination.  Borehole and Monitoring Well Installation: Drill four boreholes at disperse locations across the Site and complete the borings as groundwater monitoring wells. The purpose is to evaluate potential impacts to subsurface soil and groundwater related to former site activities. If results of the UST removal indicated potential release of petroleum hydrocarbons then soil from the borings and groundwater from the wells were to also be analyzed for petroleum hydrocarbons.  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.  Phase II ESA Report: Prepare a Phase II ESA report that summarizes the investigation and presents the investigation and risk assessment results. 2.2 Project Objectives The objective of this Phase II ESA was to: 1) complete a soil and groundwater assessment of potential environmental impacts, if any, associated with use of herbicides and pesticides, and 2) to remove and evaluate potential impacts to subsurface soil and groundwater associated with the heating oil UST. 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 that 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) used for this project were developed to ensure data quality and to define procedures for data collection. DQOs were defined in the site-specific QAAP ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 5 (TerraGraphics, 2012) and 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 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 6 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 Site. Field work was completed in general accordance with a site-specific health and safety plan (HASP) and Standard Operating Procedures (SOPs) presented in the site specific QAPP (TerraGraphics, 2012) 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 There were no deviations to the site-specific QAPP during completion of the Phase II ESA at the Site. 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 Soil and Groundwater Investigation Methods The Phase II ESA field investigation consisted of three main sampling tasks:  Perform area-wide surface soil sampling based on three decision units (DUs), and between one and three sampling units (SUs) per decision unit, to evaluate potential impacts associated with the historic use of bulk agricultural chemicals.  Remove the heating oil UST and perform subsurface soil sampling to evaluate potential petroleum hydrocarbon impacts.  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 (see Section 1.6). 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 Phase I ESA (STRATA, 2010) completed for the Site identified historical use of a portion of the property for bulk storage of agricultural chemicals. In addition the Phase I ESA also identified metals impacts in soil and groundwater, pesticides impacts in soil, and nutrients (nitrogen) impacts in groundwater. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 7 In accordance with the site-specific QAPP (TerraGraphics, 2012), the Site was divided into three DUs based on site history and or prominent features. Those DUs were as follows:  DU1: Eastern site office and parking area;  DU2: Central site bulk agricultural chemical storage and railroad spur; and,  DU3: Western site warehouse and staging area. Based on historic uses of the Site the sampling scheme focused more heavily on the central and western decision units which corresponded with the area of bulk chemical storage and the warehouse, respectively. A total of six, 20-point multi-increment surface soil samples were collected from each SU within the three DUs.  DU1: One 20-point multi-increment surface soil sample was obtained from the eastern site office and parking area DU;  DU2: The central site bulk agricultural chemical storage and railroad spur DU was divided into two SUs and one 20-point multi-increment soil sample was collected from each SU; and,  DU3: The western site warehouse and staging area DU was divided into three sampling units, each characterized by collecting one 20-point multi-increment soil sample per SU. Asphaltic pavement was encountered in the south portion of the DU which reduced the area where multi-increment surface soil samples could be obtained. 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 noted any visual or olfactory observations that indicated potential contamination while excavating each test pit. The multi-increment surface soil samples were labeled according to their location corresponding to the Site designation number, the decision unit within the site, the numerical sequence of the sampling unit sample collected within the decision unit and the depth of the sample interval as measured in feet below grade. As an example, the first surface soil sample obtained from the 317 West 6th Street site (site designation S2) within eastern site office area and parking decision unit (decision unit designation SS1) was labeled as S2-SS1-01 (0.5 ft.). Figure 2 shows the designation of the six 20-point multi-increment surface soil samples collected from each of the DUs. Each of the 20-point multi-increment surface soil samples 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. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 8 SURFACE SOIL INVESTIGATION – AREA WIDE SAMPLING ANALYTICAL REQUIREMENTS Media Area Number of Samples Analyses EPA Method Surface Soil Area- Wide 10 Herbicides Pesticides/Organochlorine Pesticides Organophosphate Pesticides 8 RCRA Metals 8151A 8081B 8270C 6020A/7471A RCRA – Resource Conservation and Recovery Act 3.4.2 Heating Oil UST Removal and Subsurface Soil Investigation Tetra Tech subcontracted with Roach Construction to excavate, remove and dispose of the former heating oil UST located in the eastern portion of the Site (Figure Roach Construction emptied the UST of fluids prior to excavation and disposed of them along with sludge that was removed from the tank following removal. Following removal of the UST, field personnel collected five confirmation soil samples from the base and sidewalls of the UST basin to evaluate potential impacts to soil and groundwater at the Site. A portion of each confirmation soil sample was analyzed on-site to evaluate volatile organic constituents using a calibrated photoionization detector (PID). The remaining portion of each soil sample was placed in a laboratory-provided container and placed in an ice-filled cooler. Confirmation soil samples were labeled according to the Site name (S2), “UST” indicating their association with the UST investigation, their numerical sequence, and sample depth as measured in feet below ground surface (bgs). As an example, the first confirmation soil sample obtained from the UST basin was designated as S2-UST-01 (5 ft.). The following table presents the sample designation and the location relative to the UST basin: The five subsurface soil samples obtained during the UST investigation were submitted to Eurofins Lancaster Laboratories for analysis of the parameters listed in the following table. UST CONFRIMATION SOIL SAMPLES Sample Designation Sample Location S2-UST-01 (5 ft.) Soil sample obtained from south wall of UST basin at approximately 5 feet below grade. S2-UST-02 (5 ft.) Soil sample obtained from north wall of UST basin at approximately 5 feet below grade. S2-UST-03 (5 ft.) Soil sample obtained from east wall of UST basin at approximately 5 feet below grade. S2-UST-04 (5 ft.) Soil sample obtained from west wall of UST basin at approximately 5 feet below grade. S2-UST-05 (6 ft.) Soil sample obtained from base of UST basin at approximately 6 feet below grade. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 9 UST SUBSURFACE SOIL INVESTIGATION ANALYTICAL PARAMETERS Media Area Number of Samples Analyses EPA Method Subsurface Soil UST 5 VOCs PAHs 8260B 8270C VOCs – Volatile organic compounds PAHs – Polynuclear aromatic hydrocarbons 3.4.3 Monitoring Well Installation and Groundwater Sampling Tetra Tech installed four groundwater monitoring wells at the Site to evaluate potential impacts from the RECs identified in the Phase I ESA. Figure 2 shows the monitoring well locations. As described in the site-specific QAPP, the purpose of each well was as follows:  Well S2-MW-01 was installed in the assumed upgradient location to evaluate water quality upgradient of anticipated on-site impacts.  Well S2-MW-02 was installed in the former location of the bulk agricultural chemical storage area.  Wells S2-MW-03 and S2-MW-04 were installed in the assumed downgradient groundwater flow direction to assist in evaluating COPC concentrations near the site boundary and for use in the soil leaching to groundwater pathway in IDEQ’s risk evaluation manual (REM). 3.4.3.1 Subsurface Soil Sampling Each well boring was advanced using DPT technology to a maximum depth ranging from 14 to 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 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. Soil samples were labeled according to the Site name (S2), the borehole designation and sample depth as measured in feet below ground surface. As an example, the soil sample obtained from the first borehole was designated as S2-BH-01 (12.5 ft.). Soil samples collected at the approximate air/groundwater interface from each of the four borings and from the 6 foot interval in boreholes S2-BH-02, S2-BH-03 and S2-BH-04 were submitted for laboratory analyses. Each of the soil samples were submitted to Eurofins Lancaster for analysis of the parameters listed in the following table. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 10 SUBSURFACE SOIL – MONITORING WELL INSTALLATION ANALYTICAL REQUIREMENTS Media Area Number of Samples Analyses EPA Method Subsurface Soil Monitoring Well Installation 7 8 RCRA Metals Herbicides Pesticides/Organochlorine Pesticides Organophosphate Pesticides 6010B 8151A 8081A 8141A RCRA – Resource Conservation and Recovery Act 3.4.3.2 Monitoring Well Installation and Development Monitoring wells were constructed of 2-inch diameter schedule 40 (PVC) well screen and casing. 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. Monitoring wells were designated according to the Site name (S2) and a numerical identification (e.g. S2-MW-1) 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 with less than 1 meter accuracy. The measuring point elevations were surveyed using a portable level and survey rod with well S2-MW-1 (Figure 2) designated as an arbitrary local datum of 1,000 feet. 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 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 11 GROUNDWATER SAMPLING ANALYTICAL REQUIREMENTS Media Area Estimated Number of Samples Analyses EPA Method Groundwater Site-Wide 4 PAHs Herbicides Pesticides/Organochlorine Pesticides Organophosphate Pesticides 8 RCRA Metals Nitrate/nitrite Total Phosphorus as phosphate Ammonia 8270 SIM 8151 8081 8141 6020/7471 SM 4500 SM 4500 SM 4500 RCRA – Resource Conservation and Recovery Act PAHs – Polynuclear aromatic hydrocarbons 3.5 Quality Assurance/Quality Control Sample Requirements Field personnel collected QA/QC samples to evaluate precision, accuracy, representativeness, completeness, and comparability. A total of three quality control (QC) samples were collected for this project. The following table presents the number and type of QC samples that were collected.

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. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 12 3.7 Risk Analyses Tetra Tech conducted a numerical risk evaluation using modeling software provided by the Idaho Department of Environmental Quality (IDEQ). Given the indefinite development plans for the Site, the risk evaluation was conducted using the combined data collected from all of the SUs located within each of the three DUs. Further, the results of the risk analysis also considered the data obtained from each DU with regards to potential remedial action that may be warranted in order to achieve the Site development objectives. User inputs into the model include contaminant concentrations and the potentially complete exposure pathways. The model includes default values for various parameters but can use site- specific data if sufficient justification for modifying the parameters can be provided. The 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 and each media identified in the exposure pathway. A discussion of the information used to conduct the risk evaluation is presented below. 3.7.1 Exposure Assessment For purposes of completing the exposure assessment, Tetra Tech assumed two potential scenarios regarding future development of the Site based on scenarios being considered by the City of Moscow. Scenario 1 assumed residential conditions consisting of residential and non- residential receptors as well as construction workers. Scenario 2 assumed non-residential conditions consisting of construction work and use of the site for commercial business. Scenario 1 – Residential Conditions The potential receptors and routes of exposure by media consist of the following:  Ingestion and dermal contact to surface soil by residential receptors, non-residential receptors and construction workers; and  Indoor inhalation of vapor emissions from subsurface soil and groundwater to residential and non-residential receptors. Scenario 2 – Non-residential Conditions The potential receptors and routes of exposure by media included the following:  Ingestion and dermal contact to non-residential receptors and construction workers; and  Indoor inhalation of vapor emissions from subsurface soil and groundwater to residential and non-residential receptors. 3.7.2 Contaminant Concentrations Representative concentrations of COPCs in surface soil, subsurface soil and groundwater were determined using guidance provided in 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. A list of the COPCs and ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 13 their maximum concentrations measured in the various media is included in the IDEQ Input Forms (Appendix 3.7.3 Exposure Factors The model’s 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. 3.7.4 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 have been removed. However, given there are currently two different site development scenarios, information including the type, size and locations of future structures have not yet been determined. Additionally, re-development scenarios could change over time, depending upon investor/developer and community needs as well as city review and approval procedures. Therefore, 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 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 14 4.0 PHASE II ESA INVESTIGATION RESULTS The following sections present a discussion of: 1) data validation conducted by the analytical laboratory and Tetra Tech; and 2) analytical results of soil and groundwater samples obtained as part of this Phase II ESA. Laboratory analytical results indicated several constituents detected in soil and groundwater samples exceeded their corresponding IDTLs. For that reason, Tetra Tech also completed a risk analysis to determine RATLs. A discussion of the risk assessment results is presented in Section 4.3 of this report. 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 Contract Laboratory Program (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 QC summary provided by the laboratory is included in the laboratory analytical reports in Appendix C. 4.1.1 Laboratory Quality Control Samples 4.1.1.1 Soil A review of the laboratory evaluation of soil sample QA/QC data indicated there were several compounds measured in the laboratory’s sample matrix QC sample that were outside of the range of criteria. Communications with Eurofins-Lancaster laboratory representatives indicated that this only affected the matrix spike samples. In accordance with the analytical method, no qualification of the data was required. There were also compounds detected in the laboratory control samples that were outside the acceptance limits. The analytical laboratory representatives stated the data would be accepted based on one of two reasons: 1) The recovery was within the marginal exceedance criteria where one compound for every 11 compounds in the calibration can be outside the statistical limits if the recovery is within 4 standard deviations of the statistical limits; or, 2) The recovery for the compound in the laboratory control sample (LCS) was high and this compound was not detected in the associated sample. Based on these guidelines, no qualification of the data was required. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 15 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 qualified as estimated. 4.1.1.2 Water A review of the laboratory evaluation of water sample data indicates the concentration of 2,4-DP measured in the LCS exceeded the maximum value, Discussions with the analytical laboratory representative indicated that the analytical results would be considered biased high for that compound. The sample from well S2-MW-01 exhibited 2,4-DP at a concentration greater than the PQL. In addition, the following compounds were outside the specified limits in the matrix quality control sample:  Demeton-S;  Famphur; and,  Naled. Discussions with the analytical laboratory representative indicated that 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 (RPD) 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 qualification 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 qualified by the laboratory with a indicating the value is estimated. 4.1.2 Field Quality Control Samples 4.1.2.1 Field Duplicate A field duplicate soil sample was obtained from surface soil sampling site S2-SS2-02 A review of that data indicated the RPD between the natural and duplicate sample for arsenic, lead and silver were within the acceptable RPD of 50%. Qualification of the associated data was not required. A field duplicate sample was also obtained from the subsurface soil sampling site S2-BH-04 (10 ft.). The RPD of the analytes detected in the natural and duplicate samples were within the acceptable RPD of 50%. Qualification of the associated data was not required. One field duplicate groundwater sample was obtained from well S2-MW-03. The RPD for lead in the natural and duplicate samples was outside the acceptable criteria of 30%. Affected data was qualified with an The RPD of the remaining analytes detected in the natural and duplicate sample were with the acceptable criteria. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 16 4.1.2.2 Equipment Rinseate Blank (Equipment Blank) One equipment rinseate blank was collected by field personnel during this investigation following soil sampling associated with the UST investigation. The equipment rinsate blank did not exhibit detectable concentrations of target analytes (volatiles and semi-volatiles). Therefore, no qualification of the data was required 4.2 Soil and Groundwater Sample Results The following section presents a discussion of field and laboratory analytical results of soil and groundwater samples obtained during this Phase II ESA investigation. 4.2.1 Site-Wide Surface Soil Samples Table 1 presents the surface soil analytical results. Figure 2 shows the location of the surface soil samples. A review of those data indicates the following:  Metals: o Arsenic exceeded the IDTL (0.391 milligrams per kilogram (mg/kg)) in five of the six surface soil samples but was less than the background concentration of 15 mg/kg for the Spokane, Washington area (WDOE, 1994). o Mercury exceeded the IDTL (0.00509 mg/kg) in four of the six surface soil samples but was less than the RATLs for both Scenario 1 (0.968 mg/kg) and Scenario 2 (14.7 mg/kg). o Silver exceeded the IDTL in the two of the six surface soil samples but did not exceed the RATL for Scenarios 1 or 2.  Pentachlorophenol: Pentachlorophenol was detected in four of the six surface soil samples. The surface soil sample from S2-SS1-01 (0.5 ft.) exceeded the IDTL but was less than the RATL-1s for both Scenario 1 and Scenario 2. Concentrations of pentachlorophenol in the remaining three surface soil samples were less than the RATLs for Scenarios 1 and 2.  Pesticides: Several pesticides including Alpha BHC, Beta BHC, Gamma BHC-lindane, DDT and Dieldrin exceeded their respective IDTLs. Two of these constituents also exceeded RATL-1s, including: 1) DDT detected in the sample from S2-SS2-01 (0.5 ft.) exceeded the RATL-1 for Scenario 1; and 2) dieldrin detected in the sample from S2- SS2-02 (0.5 ft.) exceeded the RATL-1 for Scenario 1. The distribution of subsurface soil sample locations that exhibited concentrations of COPCs exceeding IDTLs were widespread and may indicate either wide spread usage and/or redistribution of contaminants through site activities. Based on the results, the distribution of pesticides that exceeded RATL-1s appears to be limited to the central site bulk agricultural chemical storage and railroad spur DU. 4.2.2 Heating Oil UST Removal Soil Investigation Tetra Tech obtained soil confirmation soil samples from each wall and the base of the former UST basin. Field headspace screening results of the soil samples did not exceed 0.5 parts per million (ppm) and; therefore, did not indicate the presence of petroleum hydrocarbon impacts. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 17 Field personnel noted that no staining or odor indicative of petroleum hydrocarbon impacts were observed while obtaining the confirmation soil samples from the former UST basin. The UST did not exhibit any pitting, corrosion or holes that would indicate a potential release of the heating oil into the environment. Table 2 summarizes laboratory analytical results of confirmation soil samples obtained from the former UST basin. The following is based on a review of that data:  Volatile organic compounds (VOCs): Acetone was detected in the confirmation soil samples collected from the north wall, east wall and base of the UST basin. However, all the concentrations were below the IDTL and the Scenario 1 and 2 RATL-1 values. Benzene was detected in the confirmation soil sample collected from south wall, north wall, west wall and UST basin. However, all benzene concentrations were below the IDTL and RATL-1 values.  Semi-volatile organic compounds (SVOC): Soil samples obtained from the north wall, east wall, west wall and UST basin exhibited detectable concentrations of several SVOC constituents. However, only benzo(a)pyrene concentrations measured in the east wall, west wall and base of the UST basin confirmation soil samples exceeded the IDTL of 0.0422 mg/kg. None of the concentrations exceeded their respective Scenario 1 and 2 RATL-1 values. 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 and sandy gravel. The air-water interface was encountered at approximately 9 to 10 feet bgs. Appendix D includes the boring logs. Table 3 summarizes laboratory analytical results of the seven 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 but were less than the background concentration for the Spokane, Washington area (15 mg/kg; WDOE 1994).  Mercury: The subsurface soil sample collected from the 12.5-foot depth interval in boring S2-BH-01 exhibited mercury exceeding the IDTL but the concentration was less than the RATL-1 for both Scenario 1 and Scenario 2.  Silver: The subsurface soil sample collected from the 6-foot depth interval in boring S2- BH-03 exhibited silver exceeding the IDTL but the concentration was less than the RATL-1 for both Scenario 1 and Scenario 2.  Pesticides: Several pesticides including Alpha BHC, Beta BHC, Gamma BHC-lindane, DDT and Dieldrin exceeded their respective IDTLs. DDT detected in the sample from S2-SS2-01 (0.5 ft.) exceeded the RATL-1 for Scenario 1 but not the RATL-1 for Scenario 2. Dieldrin detected in the sample from S2-SS2-02 (0.5 ft.) exceeded the RATL-1 for Scenario 1 but not the RATL-1 for Scenario 2. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 18 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 (S2-MW-1 through S2-MW-4). Figure 3 presents groundwater elevations and groundwater contours developed using May 2012 groundwater monitoring data. A review of the data indicates the following:  Depth to water measured in the four monitoring wells during the May 2012 monitoring event ranged from 4.88 feet below the measuring point in well S2-MW-4 to 5.35 feet below the measuring point in well S2-MW-01.  Groundwater contours developed using the May 2012 monitoring data indicates that groundwater flow direction is to the northwest under a relatively flat gradient of 0.002 feet per foot.  Groundwater samples obtained from monitoring wells S2-MW-01, S2-MW-02 and S2- MW-04 exhibited detectable concentrations of several pesticides; however, all concentrations were less than their corresponding IDTLs.  The groundwater sample obtained from well S2-MW-01 exhibited detectable concentrations of DDT and endosulfan; however, concentrations for both were less than their corresponding IDTLs.  The groundwater samples from wells S2-MW-02, S2-MW-03 and S2-MW-04 exhibited total nitrite/nitrate nitrogen values of 38,700 micrograms per liter (µg/L), 18,100 µg/L and 62,500 µg/L, respectively. All three samples exceeded 10,000 µg/L IDTL for total nitrite/nitrate nitrogen.  In general, the lowest concentrations of nutrients (total nitrite/nitrate, phosphorus and ammonia) were detected in the groundwater sample obtained from well S2-MW-1. As previously stated, groundwater flow direction interpreted from the May 2012 monitoring event indicates well S2-MW-1 is located in the upgradient area of the Site. Additional monitoring would be required to evaluate seasonal fluctuations in groundwater elevations and flow, and concentrations of COPCs. Seasonal monitoring would also assist with evaluation of potential contributions of COPCs and nutrients from off-site sources (e.g. other industrial and agricultural businesses). 4.3 Risk Analysis The IDEQ risk evaluation was conducted using two development scenarios. Potential receptors for Scenario 1 consisted of residential and non-residential receptors as well as construction worker receptors. Scenario 2 assumed commercial business development that would preclude use as residential property. Potential receptors for Scenario 2 consisted of non-residential receptors and construction worker receptors and use of the site for commercial business operations. Risk analysis included an evaluation of surface soil, subsurface soil, and groundwater. At this time, the size and number of building(s) that will be constructed has not yet been finalized and, until re-development plans are approved through review procedures by the City of ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 19 Moscow, building footprints could change in the future. Therefore, the building footprint, which impacts the inhalation of vapors exposure pathway is unknown. Under IDEQ’s risk evaluation program, additional assessment or remediation is required if the risk exceeds 1X10-5 or the hazard index exceeds 1. Appendix E includes the output forms provided by the IDEQ software program. 4.3.1 Analytical Results Discussion A review of the analytical data indicates that arsenic was detected in most of the surface soil samples at concentrations exceeding the IDTLs. However, none of the arsenic concentrations exceeded the concentration that is considered background in the Spokane, Washington area (15 mg/kg; WDOE 1994). Therefore, no further evaluation with respect to arsenic is warranted. While several pesticides were detected in soil samples across the Site, only DDT and dieldrin were detected at concentrations above their corresponding Scenario 1 RATLs in surface soil samples obtained from DU2, the central site bulk agricultural chemical storage and railroad spur (Table Confirmation soil samples obtained from the former heating oil UST exhibited detectable concentrations of several VOC and SVOC compounds. Only the benzo(a)pyrene concentrations measured in three subsurface soil samples exceeded the IDTL but all of the concentrations were less than the RATL-1 values for both Scenario 1 and Scenario 2. As discussed in Section 3.7 the UST appeared to be in relatively good condition and did not exhibit any indications of a release. The source of the VOC and SVOC compounds was not determined, but was likely a result of overfills or spills associated with tank filling activities. Subsurface soil samples obtained from borings completed as groundwater monitoring wells exhibited arsenic concentrations exceeding the IDTL but were less than the concentration considered as background level (15 mg/kg). In addition, the arsenic concentrations were less than the RATL-1 for both Scenario 1 and Scenario 1. For those reasons, arsenic concentrations detected in subsurface soil are not considered further in the evaluation as COPCs. Mercury and silver were detected in two subsurface soil samples. The screening levels for these two metals are based on groundwater protection. None of the groundwater samples exhibited detectable concentrations of mercury or silver. Several pesticides were detected in groundwater samples from the Site but were less than their respective IDTLs. Tetra Tech evaluated the potential impacts to groundwater from the DDT and dieldrin detected at concentrations above their respective RATLs in surface soil. The DDT and dieldrin IDTLs are based on protection of groundwater. DDT was detected in the groundwater sample from well S2-MW-01, but at a concentration less than the IDTL (Table Dieldrin was not detected in any of the groundwater samples obtained from the four wells in May 2012. Therefore, DDT and dieldrin detected above the RATLs in surface soil at the Site likely do not pose a risk to groundwater at the Site as concentrations in groundwater were not above the IDTLs. Seasonal groundwater monitoring would allow for better characterization of any potential fluctuation in concentration of COPCs. 4.3.2 Scenario 1 – Residential Conditions Using the Scenario 1 input data, IDEQ’s software calculated a cumulative risk to both child and age-adjusted residential receptors that exceeded the threshold value of 1x10-5. The risk exceedance is predominantly due to potential exposure to impacted surface soil through ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 20 inhalation of vapors, dermal contact and accidental ingestion. As discussed in Section 3.7, the risk evaluation was conducted using the combined data collected from all of the SUs located within each of the three DUs. A comparison of the RATL-1s generated by the software to analytical data obtained from each of the three DUs, indicates the following:  The eastern site office area and parking area DU (DU1) and the western site warehouse and staging area DU (DU3) (Figure 2) did not exhibit COPCs exceeding their respective RATLs. Therefore, no remedial actions would likely be required in order to meet unrestricted development for those two DUs.  The central site bulk agricultural chemical storage and railroad spur DU (DU2) was the only DU to exhibit concentrations of COPCs exceeding Scenario 1 RATL-1s. The contaminants of concern (COCs) identified by the model results for this DU are DDT and dieldrin. If concentrations of those two compounds in surface soil were addressed then the Site may meet the specified target risk levels and allow unrestricted development. Otherwise deed restrictions, or other institutional or engineering controls to the exposure risk in surface soil may be required if residential development of the Site is desired Also under Scenario 1, the software indicated the hazard index for residential receptors and the cumulative risk and hazard index for non-residential receptors and construction worker receptors were less than their corresponding threshold values. 4.3.3 Scenario 2 – Non-residential Conditions Scenario 2 considered developing the Site for commercial purposes thereby eliminating residential receptors. Using Scenario 2 input data, the software-calculated risks and hazard indices for non-residential receptor and construction worker receptor did not exceed the thresholds values for any of the three DUs. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 21 5.0 SUMMARY AND CONCLUSIONS The Phase II ESA and risk evaluation at the Site identified several COPCs in surface soil and subsurface soil exceeded their corresponding IDTLs. However, most of the COPCs were either less than background concentrations or were less than RATL-1s generated using the IDEQ software. In general, the surface soil sample obtained from hand excavated test pits exhibited the highest concentrations of COPCs and the highest risk appears to be associated with pesticides detected in two surface soil samples obtained from DU2, the central site bulk agricultural chemical storage and railroad spur. DDT and dieldrin are considered COCs for the Site based on the risk assessment. Based on the data obtained and results of the risk analyses the following is a preliminary list of options for moving toward site development.  Perform additional site-specific investigation of the areas of concern, as needed for remedial action planning.  Perform a detailed Human Health Risk Assessment. This would allow for potential modification of site-specific parameters based on a specific re-development scenario. The risk assessment would be performed by a qualified and experienced toxicologist.  Conduct a remedial alternatives evaluation that would consider potential options for managing impacted soil at the Site. This would include evaluation of options related to no action, soil removal and/or treatment, and evaluation of potential engineering and institutional controls. ---PAGE BREAK--- FINAL Phase II Environmental Site Assessment Greater Moscow Area Coalition Brownfield Project 317 West 6th Street City of Moscow Moscow, Idaho Tetra Tech May 1, 2013 22 6.0 REFERENCES Idaho Department of Environmental Quality (IDEQ) 2004, Idaho Risk Evaluation Manual, Final.

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. 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).
