(Tetra Tech) prepared this sampling and analysis plan (SAP) for the City of Moscow to guide the Phase II Environmental Site Assessment (ESA) of the Old Dumas Seed Site (the “Site”) in Moscow, Idaho (Figure 1, Appendix The Phase II ESA is being completed as part of the Greater Moscow Area Coalition Brownfield Project to evaluate potential impacts to soil and groundwater from historical use of the Site. This SAP was developed based on information gathered during a previous Phase I ESA completed Tetra Tech (Tetra Tech, 2012). Project personnel will use this SAP, the Master Quality Assurance Project Plan (QAPP in Appendix B; TerraGraphics, 2011), and a Health and Safety Plan (HASP; in Appendix C) to complete the investigation. Together, these three documents comprise the project Work Plan. This SAP is organized as follows: Section 1 provides an introduction; Section 2 presents the scope of work and objectives of the investigation, Section 3 presents investigation methods and Section 4 presents references. Appendix A presents figures, Appendix B the Master QAPP, Appendix C Tetra Tech’s HASP, and Appendix D standard operating procedures (SOPs). 1.1 Key Personnel Key personnel involved in this Phase II ESA and their responsibilities are listed in the table below. KEY PERSONNEL – PHASE II ESA Name Title/Responsibility Jeffery B. Jones City of Moscow Economic Development Specialist, AICP, Project Manager; Terri Griffith USEPA Brownfields Project Officer Steve Gill IDEQ Coeur d’Alene Regional Office Brownfields Program Specialist Aaron Scheff IDEQ State Brownfields Program Manager Natalie Morrow Tetra Tech Project Manager Jon Welge Tetra Tech Assistant Project Manager To Be Determined Field Investigation 1.2 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. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 2 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. 1.2.1 Historical and Current Condition 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 observed during Tetra Tech’s 2012 Phase I ESA (Tetra Tech, 2012). 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 were present on the southern and central portions of the Site. Mill The Mill structure (also labeled as Feed Mill on Sanborn Fire Insurance Maps) is 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 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 this Phase I ESA. An approximately 10,000-gallon above-ground storage tank (AST) was located at the Mill structure and resides partially outside, beneath the bag-house structure, and partially inside the former Mill building. The AST was used for molasses storage and, at the time of the Phase I ESA site visit, still contained some residual amounts of molasses. The exterior of the AST was labeled that its original, intended contents were unleaded gasoline. The piping and valves for the molasses AST were located inside the former Mill structure. Warehouse The Warehouse structure (also labeled as Seed Warehouse and Packaging on Sanborn Fire Insurance Maps) is 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 is a four-story, wood post and beam structure with a corrugated metal exterior. The structure was used for sorting and screening pea and lentil products and included many transfer chutes and scoop-type conveyor belts. The structure also includes an electrically-powered lift/elevator. A covered load-out drive-through for farm trucks is 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) is located on the northeast portion of the Site. The Power Plant structure adjoins the east wall of the Warehouse. The Power Plant was found to be mostly intact at the time of the Phase I ESA site reconnaissance. The power plant is of brick and mortar construction and includes and 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. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 3 Scale and Scale-House The Scale and Scale-House adjoin the eastern property boundary, proximal to North Almon Street. The Scale House is a stick-built structure with both T-111 type composite wood siding and wood siding, with a pent-like roof. The truck scale adjoins the east side of the Scale House, along the eastern property boundary of the Site. An approximately 300-gallon 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. 1.3 Previous Investigations Previous investigations at the Site have included a Phase I ESA completed by TerraGraphics in 2007 (TerraGraphics, 2007), asbestos abatement of Site structures completed by IRS Environmental in (IRS Environmental, 2007), and a Phase I ESA completed by Tetra Tech (Tetra Tech, 2012). The following sections summarize each of those investigations. 1.3.1 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, wooed 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. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 4 1.3.2 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. 1.3.3 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 has 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. 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, this SAP does not currently address removal and disposal of those containers. 1.4 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 site visit, Tetra Tech observed the ground surface at the Site does 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. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 5 1.5 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. 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, 2012); 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, 2012). 1.6 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 this project is 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 will be reviewed and compared with applicable soil screening levels and groundwater standards. A risk assessment will be 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. 1.7 Contaminants of Potential Concern The Site has been used as a grain, pea, or lentil processing and storage facility. Pesticides, rodenticides, fumigants, and possibly fungicides may have been repeatedly applied to the ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 6 structures on the Site and around the exteriors of the Site structures. The Site also had one, and possibly two, USTs. One UST contained gasoline and was removed in the 1990s. The other possible UST potentially held heating fuel oil. It is unknown whether the tank was removed. 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--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 7 2.0 SCOPE OF WORK AND OBJECTIVES The following sections present the site-specific scope of work, project objectives and data quality objectives (DQOs) for this Phase II ESA. The Master QAPP (Appendix B) presents DQOs for the overall brownfield project. 2.1 Scope of Work The scope of work was developed based on information obtained during the 2012 Phase I ESA (Tetra Tech, 2012) and the COPCs identified for the Site (see Section 1.7). The scope of work for this project consists of three main tasks:  Phase II ESA: Perform a soil and groundwater investigation. Both an area-wide and focused investigation will be performed to address site concerns.  Risk Assessment: Tetra Tech will perform a risk assessment using the Idaho Department of Environmental Quality (IDEQ) Risk Evaluation Manual (REM) for guidance. The risk assessment will be performed to evaluate what, if any, risk contamination in site soil and/or groundwater may pose to human health or the environment.  Phase II ESA Report: Prepare a Phase II ESA report summarizing the investigation and presenting the investigation and risk assessment results. As mentioned in Section 1.3, ReHistoric has stated that they have plans 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 of these containers are not included in this Phase II ESA scope of work. 2.2 Project Objectives The objective of this Phase II ESA is 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 will be compared to applicable screening and/or cleanup levels. The goal of the investigation is to provide sufficient data to perform a risk assessment, evaluate potential cleanup alternatives that are protective of human health and the environment, and, in the future, aid in evaluating potential redevelopment plans. Depending upon the results, additional remedial assessment may be required to support remedial action planning and remedial action. 2.3 Data Quality Objectives The DQOs for this project were developed to ensure data quality and to define procedures for data collection. DQOs were developed following recommendations in EPA guidance documents (EPA, 1994 and 1998). The DQO process for the Brownfield project is also discussed in detail in Section 1.4 of the Master QAPP (Appendix 2.3.1 Problem Statement The Site is located within a former railroad and industrial use corridor that contain many abandoned and distressed properties in Moscow, Idaho. Phase I ESA investigations completed at the Site identified potential RECs and COPCs associated with the historic use of pesticides ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 8 and herbicides and two former USTs. The City of Moscow is interested in evaluating whether COPCs have negatively impacted the Site and what measures should be taken to abate those environmental issues. Media potentially affected by historic use include surface soil, subsurface soil, and groundwater. PROBLEM STATEMENT SUMMARY Investigation Area Potential Sources of Contamination Site-wide Pesticide and possible herbicide application in and around site structures Scale House Former USTs 2.3.2 Decision Statement The Site assessment will involve collecting environmental data to support a risk assessment, develop and evaluate cleanup alternatives, and/or evaluate potential redevelopment options. Surface and subsurface soil will be evaluated on an area-wide and focused basis. Groundwater will be sampled to evaluate potential groundwater impacts from source areas as well as in upgradient and downgradient areas of the Site. To assess the feasibility of cleanup and/or redevelopment of the Site, Tetra Tech will evaluate available data and make decisions based on the following decisions statements:  Are there portions of the Site that will not require any assessment or cleanup prior to redevelopment and/or continued use?  Are there portions of the Site that contain contaminants above cleanup levels that would preclude residential, commercial, and/or recreational redevelopment?  Are there portions of the Site that contain contaminants that have the potential to affect human health and/or the environment? 2.3.3 Decision Inputs Data required to address the decision statement may include physical and chemical characteristics of surface soil, subsurface soil and groundwater. Where enough data are available, data requirements may also include estimating contaminant waste volumes. There is no known prior environmental data. All data collected and evaluated during this Phase II assessment will be compared to applicable State and Federal screening levels and standards. Specific decision inputs for this ESA are summarized in the table below. DECISION INPUTS Source Material Typical Data Parameters Data Uses Surface soil surrounding site structures Metals-based pesticides, organochlorine pesticides, and organophosphate pesticides, herbicides, metals Evaluate site-wide potential for contamination and evaluate potential risks to human health and the environment. Compare contaminant concentrations to applicable state and federal standards. Subsurface soil in suspected vicinity of former USTs Gasoline and diesel range petroleum hydrocarbons, lead Gasoline and diesel range petroleum hydrocarbons, lead. Compare contaminant concentrations to applicable state and federal standards. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 9 DECISION INPUTS Source Material Typical Data Parameters Data Uses Groundwater Metals-based pesticides, organochlorine pesticides and organophosphate pesticides, herbicides, gasoline and diesel range petroleum hydrocarbons, lead Metals-based pesticides, organochlorine pesticides and organophosphate pesticides, herbicides, gasoline and diesel range petroleum hydrocarbons, and metals. Compare contaminant concentrations to applicable state and federal standards. 2.3.4 Study Boundary The lateral study boundary for the Site consists of the combined property boundary for the two parcels. The vertical study boundary for subsurface borings and monitoring well installation is approximately 5 feet below first encountered static water or the appropriate level such that the monitoring wells can be installed to appropriately account for seasonal fluctuations in groundwater levels. Figure 1 shows the site boundary and locations of the Site structures prior to demolition work. Figure 2 shows the approximate proposed locations of area-wide and focused soil investigation locations, and monitoring well locations. 2.3.5 Decision Rule Regulatory screening levels and standards will be used to evaluate data collected during the assessments.  An initial comparison of soil and groundwater concentrations will be made to determine which analytes, if any, exceed established regulatory screening levels and standards.  A risk assessment will be performed to evaluate what risks contamination at the Site poses to human health and the environment.  Based on the initial data comparison and the risk assessment results, decisions will be made as to whether additional investigation or corrective action is needed. Tetra Tech will compare surface and subsurface soil, and groundwater analytical results to the IDEQ REM Initial Default Target Levels (IDTLs; IDEQ, 2004), EPA Regional Soil Screening Levels (RSLs; EPA, 2011), IDEQ petroleum Rule for Residential Use Screening Levels (RUSLs) (IDEQ, 2011). A risk assessment will also be performed according to IDEQ’s REM to evaluate the potential for impacts to human health and the environment. 2.3.6 Tolerable Limits of Decision Errors Decision errors are incorrect conclusions about a site caused by using data that are not representative of site conditions due to sampling or analytical error. Limits on decision error are typically established to control the effect of sampling and measurement errors on decisions regarding a site, thereby reducing the likelihood that an incorrect decision is made. The null hypothesis is that a site is contaminated. A false positive decision error is one that decides a site is clean when, in actuality, it is not clean. A false negative decision error is one that decides a site requires cleanup when, in actuality, it requires no cleanup. False positive and negative decision errors should be minimized as much as possible during this project. Formal limits on decision error are not necessary in areas where the goal of the assessment is to define the boundaries of known contamination (EPA 1998). ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 10 The total study error will be minimized by collecting an appropriate number of environmental samples deemed necessary by the assessment team that are intended to represent the range of concentrations present at each site in question. The sampling program is designed to reduce sampling error by specifying an adequate number and distribution of samples to meet project objectives. 2.3.7 Sampling Design Section 3 outlines the field assessment design for the Site. It specifies sampling protocols, analytical methods and the types and numbers of samples to be collected during the assessment. The assessment design is based on a review of historic data and/or previous investigations completed at the Site and RECs identified during the Phase I ESA (Tetra Tech, 2012). The general sample design consists of:  Surface and subsurface soil sampling – Surface and subsurface soil sample results will be used to evaluate concentrations of COPCs in surface and subsurface soil at the Site. Results will also be used to identify direct and indirect routes of exposure to human- health, based on contaminant type and concentration, and potential site reuse scenarios. IDEQ defines surface soil as soil from the ground surface to 1 foot below ground surface (bgs) and subsurface soil as soil greater than 1 foot bgs.  Groundwater sampling – Groundwater sample results will be used to evaluate concentrations of COPCs in groundwater at the Site and to evaluate potential direct and indirect routes of exposure to human health and the environment. 2.3.8 Project Timeline The ultimate project timeline will be dependent upon review time of documents, subcontractor availability, weather, and site access. The following presents a tentative project timeline for this Phase II ESA:  SAP and HASP (Appendix C) preparation and approval – February/March 2012  Site Utility Locates – March/April 2012  Field Investigation – March/April 2012  Laboratory Analyses – April/May 2012  Risk Evaluation – April/May 2012  Draft Report Preparation and Submittal – May/June 2012  Report Finalization – June 2012 ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 11 3.0 FIELD ASSESSMENT AND REPORTING The following sections present the methods of investigation that will be used during this Phase II ESA and reporting of the data. Section 4 discusses data evaluation. 3.1 Standard Operating Procedures and Master QAPP Field personnel will review the Master QAPP (Appendix B) and use standard operating procedures (SOPs) as guidelines for conducting the field investigation. Field personnel will review each of the SOPs in Appendix D prior to implementing field work. The following table lists Tetra Tech’s SOPs for this project. SOP # SOP SOP # SOP 5 Multi-Parameter Field Meter 17 Monitoring Well Development 9 Sample Packaging and Shipping 20 Field Measurement of Groundwater Level 10 Field Forms 22 Drilling Soil Sample Collection 11 Equipment Decontamination 24 Soil Sample Preparation and Preservation 12 Sample Documentation 27 Field Measurement of Volatile Organic Compounds Headspace 13 QC Samples 44 Ionization Device (PID or FID) Operation 16 Monitoring Well Construction 46 Low-Flow (Minimal Drawdown) Groundwater Sampling Equipment used in the field will be calibrated according to manufacturer guidelines. Field personnel will document any calibration procedures in the field notebook. 3.2 Utility Locates Project personnel will contact utility locators to have utility lines located at least 2 business days prior to implementation of the field investigation. A private utility locate company may be necessary to locate private utility lines on the Site because many utility locates only locate to the edge of the property. Location of utilities may also require coordination with personnel familiar with the Site to help locate underground lines. 3.3 Soil and Groundwater Investigation Methods The Phase II ESA field investigation consists 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 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. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 12 Field personnel will document all field activities on field logs, in the field notebook, and on field maps. Photographs will also be taken to document site investigation activities. The following sections discuss the investigation tasks and methods. 3.3.1 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 are 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 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 50-foot by 50-foot grid resulted in a total of 36 cells. Field personnel will collect grab samples of surface soil at the approximate center of every third grid cell, resulting in a total of 12 sample locations (Figure Field personnel will use SOPs 10, 11, 12, and 24 as guidance during the work. Surface soil samples will be obtained by hand excavating shallow test pits from the surface to approximately 0.5 feet below ground surface (bgs). Samples will be obtained from the central portion of each cell with the following exceptions:  For cells which are located in an area of high vehicular traffic and/or disturbance from site demolition activities, the sample location will be adjusted in the field to an area within that cell that is less disturbed (e.g. adjacent to a site structure), as possible.  Where the center of the cell falls on a structure and where that structure occupies only a portion of the cell, the sampling location will be adjusted in the field to an area with soil and within 10 feet the structure. For example, sample points A3, D3, and F1 will require adjustment to the closest available soil area within the grid cell. The presence of site demolition debris may also result in a required adjustment of sample points.  Cells that fall entirely within an area occupied by a structure will eliminated from the number of samples to collect. For example, the sample point at C2 was eliminated, resulting in and estimated 11 soil samples instead of 12. Field personnel will also log the lithology encountered in each test pit. Field personnel will also note any visual and olfactory observations that indicate potential contamination is present. Field personnel will also document the location of the test pit on a field map. The coordinates of each sample location will also be recorded using a hand-held resource grade global positioning satellite (GPS) unit for placement on geo-referenced report figures. The hand-excavated test pits will be labeled according to their coordinate in the grid system. For example, a test pit completed in the grid square A,1 will be labeled TP-A1. Samples will be labeled according to the Site name (Dumas Seed - “DS”) their corresponding test pit number and sample depth. For example, a sample collected from TP-A1 from the 0- to 0.5-foot depth interval will be labeled DSTP-A1(0-0.5’). ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 13 Soil samples will be placed in laboratory-provided sample containers and transferred immediately to a cooler containing doubled re-sealable bags filled with ice. All samples will be handled and shipped under standard chain-of-custody procedures. Each surface soil sample will be analyzed for the parameters listed in the following table. Section 3.5 discusses quality assurance/quality control (QA/QC) sample requirements for this project. Samples will be analyzed by a NELAP-accredited laboratory for analysis.

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 (550 gallons), that it was used to store diesel fuel and it included copper piping. Tetra Tech believes that if the UST was located on-site, it may have been used to supply an oil-fired heating unit for the Scale House. To evaluate whether contamination exists in association with the USTs, the subsurface soil investigation will focus on the area surrounding the Scale House and scale. Tetra Tech will subcontract with a direct-push technology (DPT) drilling subcontractor to obtain soil samples from six borings to be excavated around the perimeter of the Scale House and scales. Field personnel will obtain continuous soil samples from each boring beginning at grade to an estimated maximum depth of 15 feet below ground surface (bgs), the anticipated depth to first encountered groundwater. Figure 3 presents the proposed DPT subsurface soil sample locations. The exact locations will be determined in the field based on site conditions. Field personnel will use SOPs 10, 11, 12, 22, 27, and 44 as guidance during the work. Field personnel will log the soil encountered in each boring and record 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 will be analyzed on-site for volatile organic constituents using a photoionization detector (PID). The remaining portion of the sample will be 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 will be submitted for laboratory analysis. In addition, the soil sample collected at the air/groundwater interface will also be submitted for laboratory analyses. In the event that field screening does not indicate petroleum hydrocarbon impacts then only the sample obtained from the air/groundwater interface in that boring will be submitted for laboratory analyses. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 14 Samples will be labeled according to the Site name (Dumas Seed - their corresponding DPT boring number (e.g. DPT-1), and sample depth interval of soil collection, and date and time of collection. For example, a sample collected from boring DPT-1 from the 5- to 6-foot depth interval will be labeled Field personnel will also document the location of the DPT boring on a field map. The coordinates of each DPT boring location will also be record using a hand-held resource grade global GPS unit for placement on geo-referenced report figures. Up to 12 subsurface soil samples (up to two samples per boring) will be submitted for laboratory analyses. Section 3.5 discusses QA/QC sample requirements for this project. Samples will be analyzed by a NELAP-accredited laboratory for analysis.

One of the monitoring well locations will coincide with one boring installed as part of the UST investigation near the Scale House (Section 3.3.2). Figure 2 shows the proposed monitoring well locations. Final placement of the wells, particularly DSMW-2, will be based upon site conditions. The purpose of each well is as follows:  DSMW-1: Potential background well installed to evaluate water quality upgradient of anticipated on-site impacts. This well would also provide information from potential contaminants that may be entering the Site from the former implement business and railroad station, both in an anticipated upgradient to cross-gradient direction (Tetra Tech 2012).  DSMW-2: Well will be installed in Scale House area to evaluate potential impacts from petroleum hydrocarbons from former USTs and any pesticides or herbicides associated with application to the eastern portion of Site.  DSMW-3: Well will be 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. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 15  DSMW-4: Well will be installed near the western site boundary to evaluate water quality in western portion of the Site and water quality migrating off site. 3.3.3.1 Subsurface Soil Sampling Soil samples will be obtained as each borehole is advanced to document subsurface soil conditions. Each boring will be advanced to an estimated maximum depth of 20 feet bgs, approximately 5 feet below the anticipated static groundwater level. Soil samples will first be collected using DPT technology to approximately 5 feet into the saturated zone, followed by re- drilling the borehole using hollow-stem auger (HSA) drilling to excavate soil and expand dimensions of the boring to accommodate well installation. Field personnel will use SOPs 10, 11, 12, 22, 27, and 44 as guidance during the work. Field personnel will log the soil encountered in each boring and record 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 will be analyzed on-site for volatile organic constituents using a PID. The remaining portion of the sample will be 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 will be submitted for laboratory analysis. In addition, the soil sample collected at the air/groundwater interface will also be submitted for laboratory analyses. In the event that field screening does not indicate potential contamination then only the sample obtained from the air/groundwater interface in that boring will be submitted for laboratory analyses. Field personnel will collect up to eight soil samples (up to two samples per well boring) during installation of monitoring wells. Samples will be labeled according to the Site name (Dumas Seed their corresponding well number (e.g. MW-1), and sample depth interval of soil collection, and date and time of collection. For example, a soil sample collected from well boring MW-1 from the 5- to 6-foot depth interval will be labeled DSMW-1(5-6’). The following table presents subsurface soil sample analyses for soil collected during monitoring well installation. Section 3.5 discusses QA/QC sample requirements for this project. Samples will be analyzed by a NELAP-accredited laboratory for analysis.

Field activities will be documented using SOPs 10 and 12 as guidance. Monitoring wells will be constructed of 2-inch diameter schedule 40 (PVC) well screen and casing. Factory slotted 0.010-inch (PVC) well screen will be incorporated in the lower 10 feet of each well. The sand filter pack around the well screen will extend 2 feet above the screened interval. Bentonite chips will extend from the top of the filter pack to approximately 1-foot bgs, followed by cement for the surface completion. Each well will be completed with a surface casing for protection; a flush mount surface completion will be used in areas where vehicular traffic is common. Following well installation, field personnel will develop each monitoring well using a surge and bail technique to remove fine-grained material and improve communication with the water- bearing strata. Wells will be allowed to rest for at least 24 hours prior to groundwater sampling. All monitoring well locations will be located using a resource grade hand held GPS unit. Depth to water measuring points will be established on the north side of the monitoring well casing and the point surveyed to an arbitrary local datum using a portable level and survey rod. 3.3.3.3 Groundwater Monitoring and Sampling Groundwater monitoring will be completed after at least 24 hours has past following well development. Field personnel will use SOPs 5, 11, 12, 20, and 46 as guidance. Depth to water will be measured in all four wells prior to conducting the sampling effort. Groundwater sampling will be completed using a peristaltic pump with dedicated disposable tubing and the EPA low-flow purge method. Field personnel will record pH, specific conductance (SC), oxidation-reduction potential (ORP), dissolved oxygen (DO) and temperature during purging. Purging will be considered completed when field parameters have stabilized to ±10%. The following table lists the analytical requirements for groundwater samples. Section 3.5 presents QA/QC sample requirements for this project. Samples will be analyzed by a NELAP- accredited laboratory for analysis.

SOP 11 will be used as guidance for equipment decontamination. Field personnel will collect surface and subsurface soil, and groundwater samples in laboratory provided containers and preserve the samples as required by the laboratory analytical method. Samples will be stored in coolers containing doubled re-sealable bags filled with ice in the field and during shipment to the analytical laboratory. Ice will be replenished as needed during the investigation and prior to shipment. Field personnel will use SOP 9 as guidance for sample packing and shipping. Samples will be shipped via overnight courier to a NELAP-accredited laboratory for analysis. Samples will be handled and transferred under standard chain-of-custody procedures. 3.5 Quality Assurance/Quality Control Sample Requirements Field personnel will collect QA/QC samples to evaluate precision, accuracy, representativeness, completeness, and comparability. Field personnel will collect blind field QC samples and use SOP 13 for guidance. Four QC samples will be collected for this project. The following table presents the number and type of QC samples.

Site-Specific DQOs were developed in Section 2. Personnel involved with field activities, evaluation of the data and reporting will use the Master QAPP as a general guide for data evaluation for this investigation. Tetra Tech data evaluations will be performed 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 will be included with laboratory analytical data reports in the Phase II ESA report. 3.7 Waste Disposal Soil generated during drilling of boreholes and installation of groundwater monitoring wells will be containerized and temporarily staged on-site pending receipt of laboratory analytical data. Soil cuttings that do not exhibit contamination greater than soil screening levels will be thin- spread on-site. If soil cuttings exhibit concentrations above soil screening levels and are within the criteria of a local landfarm operated by Roach Construction, the soil will be disposed at the Roach landfill facility. Based on discussions with Mr. Jay Roach, owner of Roach Construction, lead concentrations in the soil must not exceed 500 milligrams per kilogram (mg/kg). If lead concentrations exceed the maximum value, other disposal arrangements will be made in consultation with the City of Moscow. The quantity of purge water generated during monitoring well development and sampling will likely be very small (anticipate <20 gallons). The purge water will be thin-spread in the general vicinity of each well. If field conditions indicate water from a well exhibits gross contamination (e.g. odor, sheen, etc.) then the water generated from that well will be containerized and staged on site until analytical results are received and disposal options can be identified. 3.8 Health and Safety Plan Appendix C includes Tetra Tech’s site-specific health and safety plan (HASP) for use during completion of this project. The HASP was prepared in accordance to Occupational Safety and ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 19 Health Administration (OSHA) requirements. Prior to implementation of field work, site-specific project personnel will be added or modified in the HASP, as needed. 3.9 Reporting Draft and Final Phase II ESA reports will be prepared for this project following receipt of all final laboratory analytical reports. A risk assessment according to IDEQ’s REM will be performed. The report will present a summary of field investigation methods, present the results of the investigation and risk assessment, compare the results to IDEQ IDTLs and EPA RSLs, and present an evaluation and findings of the investigation. The report will be complete with figures, tables, and boring and well logs. Laboratory analytical results will be presented as an appendix along with their corresponding data evaluation reviews. . The report will also discuss any deviations from the sampling plan that were made during implementation of the field investigation, and any QA/QC concerns and corrective actions. The draft report will be submitted to the City of Moscow and the EPA for review and approval. The final report will be prepared following receipt of comments from the City of Moscow and the EPA. ---PAGE BREAK--- Phase II Sampling and Analysis Plan Greater Moscow Area Coalition Brownfield Project Old Dumas Seed Site City of Moscow Moscow, Idaho Tetra Tech March 6, 2012 20 4.0 REFERENCES Alt, David D. and Donald 1989.

The objective of this Quality Assurance Project Plan (QAPP) is to guide quality assurance and quality control (QA/QC) procedures for completion of Phase II Environmental Site Assessments (ESAs) in the City of Moscow Brownfields Assessment Project program boundaries. It is intended to ensure that sampling activities comply with the U.S. Environmental Protection Agency’s (USEPA) requirements for QAPPs (USEPA, 2001). The primary goals will be to characterize potential soil, groundwater, or air contamination, and to potentially provide data for use in the Idaho Department of Environmental Quality’s (IDEQ) Risk Evaluation Manual (REM) in order to determine potential hazards and/or risks associated with found contamination. The following sections list the key project personnel and their responsibilities, explain the problem(s) and site history(ies), project schedules, data quality objectives, sampling, oversight, and data validation and use. 1.1 Project/Task Organization This Master QAPP provides a general overview of the sampling strategies intended to evaluate recognized environmental conditions identified for the City of Moscow (hereafter, referred to as “the City”) Brownfields corridor and other negatively impacted and/or stigmatized areas, and to identify a streamlined format for site-specific QAPPs. Each site-specific QAPP will adhere to the same general format and organization as the following Master QAPP sections, but will be specific to that the site’s planned Phase II ESA project organization and sampling and analysis activities. Each site-specific QAPP will include the names of City of Moscow consultant personnel performing the Phase II site assessments, and will identify the subcontractors and laboratories supporting the assessment. An example organization chart is provided below in Figure 1. ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 2 Figure 1. Organization Chart This master QAPP identifies the City of Moscow and the IDEQ personnel with management oversight and the two City of Moscow consultants who will be performing the site-specific Phase II ESAs during 2011-2012.

Site-specific QAPPs will also identify the consultant contracted by the City of Moscow to perform the Phase II ESA investigation activities. The City of Moscow was awarded an USEPA Brownfields Assessment Coalition Grant (for hazardous substances contamination and petroleum contamination) in August of 2010. The City of Moscow is part of the Greater Moscow Area Coalition, which also includes the Moscow Urban Renewal Agency and Latah County. The City is using the USEPA grant funds to conduct Phase I and II ESAs, as well as Analysis of Brownfields Cleanup Alternatives (ABCAs) for multiple Brownfield properties along a former ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 4 railroad/industrial corridor, future industrial park property, and other negatively impacted and/or stigmatized areas. The primary goal of this project is to expedite redevelopment of critical distressed properties to improve environmental, economic, and social conditions for the greater Moscow community. The objectives necessary to meet this goal include the following tasks:  Conduct site inventory and site selection activities;  Prepare environmental site assessments and ABCAs for selected properties; and  Leverage project funding and assessment work to promote redevelopment of critical properties within the corridor and other negatively impacted and/or stigmatized areas. In addition to these specific objectives, the project will also have a strong component of public outreach and education that will inform the public about each phase of the project (Moscow City Council Agenda, 2011). 1.3 Project/Task Description In this section each site-specific QAPP will provide an overview of the planned Phase II investigation activities and a schedule for implementation. This section of site-specific QAPPs should also provide maps or tables that illustrate the geographic locations of field tasks and a brief overview of how the Phase II ESAs will resolve the problem or question stated in Section 1.2. 1.3.1 Description of the Project Area The majority of the properties that have been preliminarily identified for assessment through this project are located within a former railroad and industrial use corridor; however, there are other sites outside of the corridor that may also need assessment. The Brownfields corridor extends from the northern edge of Moscow’s downtown, near A Street, to the southern edge of the City, where U.S. Highway 95 leaves Moscow and heads south towards Lewiston. Figure 3 provides a site location map of the corridor. In addition to containing many of the abandoned and distressed properties in Moscow, the Brownfields corridor is densely populated with a wide range of housing types and income levels. This corridor also includes Paradise Creek, Paradise Path, and the Latah Trail which provide the downtown core with much needed green space and pedestrian access. ---PAGE BREAK--- Figure 3.

Consideration of data quality begins with the identification of data uses and data types. The USEPA Data Quality Objective (DQO) process used as a model for this project is described in USEPA Guidance on Systematic Planning Using the Data Quality Objectives Process ( QA/G-4) (USEPA, 2006). This document outlines processes that are general in nature to any environmental investigation. 1.4.1 Data Quality Objectives Process Each site-specific QAPP will identify the DQOs related to that site’s Phase II ESA. The DQO process results in a set of specifications needed to support the qualitative and quantitative design of a data collection effort. DQOs are used to assess the adequacy of data in relation to their intended use (USEPA, 2002). USEPA’s seven-step process for DQO development is presented below (Figure 4) to communicate the quality objectives for site assessment activities associated with the Moscow Brownfields corridor and other negatively impacted and/or stigmatized areas. 1.4.1.1 State the Problem The Moscow Brownfields corridor is densely populated with a wide range of housing types and income levels and contains many of the abandoned and distressed properties in Moscow. This corridor also includes Paradise Creek, Paradise Path, and the Latah Trail which provide the downtown core with much needed green space and pedestrian access. Site-specific assessments will determine if recognized environmental conditions have negatively impacted project sites within the Moscow Brownfields corridor or other negatively impacted and/or stigmatized areas. ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 7 1.4.1.2 Identify the Decision Samples will be collected at sites selected for the Greater Moscow Brownfield program. Samples will be collected and analyzed for a subset of analytes shown in Table 1. Analyte concentrations will be compared against Idaho Department of Environmental Quality (IDEQ) Risk Evaluation Manual (REM) Initial Default Target Levels (IDTLs) (IDEQ, 2004) and/or IDEQ petroleum rule for Residential Use Screening Levels (RUSLs) (IDEQ, 2011). Indoor air concentrations will be compared to USEPA regional screening levels (RSLs) (USEPA, 2011) for residental air. Site soil vapor data will be compared to USEPA RSLs (USEPA, 2011) as 10 times the resident air screening levels for subslab vapor intrusion and 100 times the resident air screening levels for deep vapor intrusion. 1.4.1.3 Identify Inputs to the Decision In order to adequately evaluate potential impacts to the project site’s groundwater, soil, and vapor, sampling and analysis are needed. Those chemical and physical characteristics needed to adequately provide information for decisions on potential constituents of concern (COCs) are provided in this QAPP (Table Specifics on those methodologies and relevant measurement characteristics can be found in Section 2.0. 1.4.1.4 Define the Study Boundaries The project sites are within the Moscow Brownfields corridor, which extends from the northern edge of Moscow’s downtown, near A Street, to the southern edge of the City, where U.S. Highway 95 leaves Moscow and heads south towards Lewiston (Figure However, other sites outside of the corridor may also need assessment. 1.4.1.5 Develop a Decision Rule The site assessments will involve collecting environmental data to support cleanup alternatives and/or redevelopment for each location. Cleanup alternatives will likely focus on cleanup or removal of routes of exposure to contamination by human and ecological receptors. To assess the feasibility of cleanup and/or redevelopment, the consultant will evaluate available data and make decisions based on the following decisions statements:  Do some portions of the site contain contaminants above cleanup levels that would preclude residential, commercial, and/or recreational redevelopment or use?  Do the contaminated materials at the site have the potential to affect human health and/or the environment?  Are there portions of the site that will not require any assessment or cleanup prior to redevelopment, remodeling or demolition, and/or continued use? 1.4.1.6 Specify Limits on Decision Errors Detection limits will meet the DQOs for comparison to the IDTLs, RUSLs, and RSLs (or multiples thereof). In order to ensure the quality of data is acceptable for use, Section 4.0 outlines all the specified tolerable limits and decision errors for the data obtained during this project. ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 8 Figure 4. DQO Process Flow Chart 1. State the Problem: Determine if recognized environmental conditions have negatively impacted the project sites within the Moscow Brownfields corridor or at other negatively impacted and/or stigmatized areas. 2. Identify the Decision: Do the identified on-site RECs result in COC concentrations that exceed Idaho’s targeted action levels IDTLs, RUSLs, RSLs)? 3. Identify Inputs to the Decision: Research and/or sample data collected from the project sites. 4. Define the Study Boundaries: Project sites within the Moscow Brownfields corridor or at other negatively impacted and/or stigmatized areas. 5. Develop a Decision Rule: Concentrations for samples collected will be compared against IDEQ REM IDTLs and/or IDEQ petroleum rule RUSLs. Vapor data will be compared to USEPA RSLs (which may also have a multiplier depending on the sample location). 6. Specify Limits on Decision Errors: Detection limits will meet the DQOs for comparison to the IDTLs/RUSLs/RSLs. 7. Optimize the Design for Obtaining Data: Samples will be collected per site-specific QAPPs to provide data for use in the REM. ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 9 1.4.1.7 Optimize the Design for Obtaining Data Samples will be collected per site-specific QAPPs to provide data for decision making. 1.4.2 Data Quality Indicators Each site-specific QAPP will present the final data quality indicators defined for that site’s assessment. 1.4.2.1 Precision Precision is a measure of data variation when more than one measurement is taken on the same sample. The precision estimate for duplicate measurements can be expressed as the relative percent difference (RPD):     % 100 2 2 1 2 1           C C C C RPD where: RPD = relative percent difference C1 = concentration of QA/QC sample C2 = concentration of associated original Acceptable precision limits are based on past databases, as defined by USEPA. Laboratory duplicate measurements will be obtained for each set of samples submitted and analyzed. 1.4.2.2 Accuracy Accuracy of laboratory analysis is assessed by measuring standard reference material and spiked samples. Standard reference materials are utilized to calibrate laboratory measurement instruments. Splitting a sample into two portions, spiking one portion with a known quantity of a constituent of interest, and analyzing both portions determine spike recovery. Spike recovery is expressed as percent recovery: % 100 ) ( %    TV OC SC RS where: %RS = percent recovery of spike SC = spiked sample concentration OC = original concentration TV = true value of the added spike Acceptable spike recovery limits are based on past data sets as defined by USEPA. 1.4.2.3 Representativeness This term expresses the degree to which the data accurately and precisely represent actual conditions or characteristics of the site. Representativeness uses background samples collected from areas isolated from, yet similar to, the site and analyzed for the same constituents. However, representativeness will most likely not be evaluated for this project. ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 10 1.4.2.4 Completeness Completeness is an estimate of the amount of valid data obtained from the analytical measurement system for a given set of data. The percent completeness is defined as the number of samples analyzed that meet the data quality goals divided by the total number of samples analyzed multiplied by 100. The completeness goal for this project is 95%. 1.4.2.5 Comparability Using standard USEPA accepted protocols; all matrix-specific samples will be collected, processed, and analyzed at sufficient detection limits, precision, and accuracy for correlation with previous available data. 1.5 Special Training/Certification Each site-specific QAPP will identify associated training and certification requirements related to the Phase II field assessment activities. A qualified Environmental Scientist will oversee all sampling activities and serve as the Site Safety and Health Officer for each site. Personnel performing sampling at each site will have training required by 29 Code of Federal Regulations (CFR) 1910.120 if necessary (Occupational Safety and Health Administration Hazardous Waste Operations Health and Emergency Response Training). Documentation of necessary training and certifications will be provided upon request. 1.6 Documentation and Records 1.6.1 Field Operation Records Each site-specific QAPP will identify record collection methods, field procedures, and any corrective actions that may take place during sampling events. 1.6.1.1 Sample Collection Records 1.6.1.1.1 Field Logbook A Rite-in-the-Rain (or similar) field notebook will be used in the field to document the samplers’ names, sample numbers, sample location points, maps and diagrams, equipment/method used for sample collection, weather conditions, and unusual observations. Field notebooks will be pre-numbered and will contain the date and signature lines. 1.6.1.1.2 Photographic Records Photographs will be taken of representative sampling locations and the surrounding site to show the area, related site activities, and sampling equipment. 1.6.1.2 Chain-of-Custody Records The chain-of-custody record will be filled out and kept to track samples from collection through delivery to the laboratory following the American Society for Testing and Materials guidance Standard Guide for Sampling Chain-of-Custody Procedures (D-4840-99) (ASTM, 2004). ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 11 1.6.1.3 QA/QC Sample Records QA/QC samples field and equipment rinsate blanks and duplicates) will be documented in the field notebook. This documentation will include custody seals, calibration history, level of standards, and the frequency and type of the QA/QC sample. 1.6.1.4 General Field Procedures The field procedures will be documented in the field notebook and will specify the method of collection bailer, low-flow peristaltic pump), location, and identify potential areas of difficulty in the actual gathering of the specimens. 1.6.1.5 Corrective Action Reports Should the primary method of sample collection fail, the corrective action or alternative method will be documented in the field notebook and reported in the subsequent final Phase II ESA letter report. For instance, should a low-flow peristaltic pump collection system fail static water is greater than one atmosphere below ground surface), a well may be sampled using hand bailers. 1.6.2 Laboratory Records 1.6.2.1 Sample Data Laboratory methods will follow the USEPA guidance, Test Methods for Evaluating Solid Waste, Physical/Chemical Methods (SW-846) (USEPA, 2008), which includes recording the date that samples were analyzed to verify holding times were met. The overall number of samples, sample location information, and date will be reported as well as any corrective action procedures for samples violating this QAPP and/or the site-specific QAPP protocol. 1.6.2.2 Sample Management Records The Laboratory will maintain detailed procedures for their recordkeeping in order to support the validity of analytical work. Each data report package submitted to the City’s contractor will contain the analytical laboratory’s written certification that the requested analytical method was run and that QA/QC checks were performed. After a technical data review conducted by the laboratory and the City’s contractor, the data will be sent to the City where it will be archived according to State or Federal records retention policies, whichever is more restrictive. 1.6.2.3 Test Methods The test methods used will be those identified in Table 1 (or per site-specific QAPPs) as appropriate for sample analysis. Should an alternative analysis be required, the laboratory will document and describe how the analyses were carried out in the laboratory. This will include sample preparation and analysis, instrument standardization, detection and reporting limits, and test-specific QC criteria. 1.6.2.4 QA/QC Reports Laboratory QA/QC methods will follow the USEPA guidance, Test Methods for Evaluating Solid Waste, Physical/Chemical Methods (SW-846) (USEPA, 2008). The report will include ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 12 laboratory QA/QC data from blanks, spikes and matrix spike duplicates, and duplicates. The City’s consultant will complete internal QA/QC to ensure the quality of the data. 1.6.3 Data Handling Records The Laboratory’s quality assurance personnel will perform the data validation. The data validation will convert raw data into reportable quantities and units by properly applying significant figures, recording extreme values, and identifying data qualifiers. The data will then be transmitted electronically and/or in hard copy to the City’s consultant, who will perform an internal QA/QC. The internal QA/QC will document the data meets the proposed DOQs. Section 2.0 Data Generation and Acquisition 2.1 Sampling Process Design Each site-specific QAPP will identify proposed sampling locations and detail the sample collection method(s) rationale for the sampling design related to the Phase II assessment. 2.2 Sampling Methods Each site-specific QAPP will identify specific procedures to be used for sample collection.

These tables can be found in Appendix B. b The asbestos analysis is performed to determine the presence or absence of asbestos-containing materials (ACMs) in the soil. If ACMs are identified in the soil a point count will be performed to determine if the asbestos concentration is greater than or less than c Site-specific QAPPs will delineate lists of metals analyzed and specify Methods for those analyses. d Some nutrients are only listed in USEPA’s National Primary Drinking Water Standards (USEPA, 2009) and not in documents found in Appendix B. Reporting limits will then meet or be less than values listed in USEPA (2009). 2.5 Quality Control Each site-specific QAPP will identify the quality control requirements related to the site-specific assessment sampling and analysis activities. ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 15 2.5.1 Field Quality Control Checks Field duplicate samples (QC samples) indicate the precision of the sampling and analysis program for detectable analytes. For solids, the field duplicate sample is one portion of a double- volume solid sample that is homogenized (mixed) before the sample containers are filled and the other portion is the primary sample. Duplicate samples for Volatile Organic Compound (VOC) analysis will be co-located with the primary sample to minimize volatilization. Duplicates are prepared by filling a second sample container with the same homogenized soil from the most recent sample area and interval, and marking the soil tag as a duplicate sample. The QC sample, along with the original sample, will be sent to the analytical laboratory. QC samples will be collected at a frequency of one per sampling event per site, or one per 20 samples, whichever is greater. For every set of samples submitted to the lab, one split will be collected and submitted to the laboratory. Split samples will be prepared during sample banking prior to shipping to the laboratory for analysis. Duplicate samples will not be made into split samples. To prepare a split sample, the soil will be thoroughly mixed by hand (while wearing disposable, single use gloves), and divided into another sample container. The new sample container and sample tag will be marked as a split sample. 2.5.2 Laboratory Quality Control Checks The laboratory QC requirements will follow the guidance outlined in the Test Methods for Evaluating Solid Waste, Physical/Chemical Methods (SW-846) (USEPA, 2008).

Specifics on each criterion are discussed in Section 1.4.2. The City’s contractor will conduct an internal data validation and QA/QC review of all data collected in the field and that provided from the Laboratory, documented by an internal memorandum. 2.10.2 Data Recording The City’s contractor will receive the data from the laboratory and prepare useful data tables. After the City’s contractor has conducted the internal data validation, the table will be updated with relevant data qualifiers. 2.10.3 Data Transformation The raw or validated data will be available for third party data transformation. 2.10.4 Data Transmittal Either Microsoft Excel © or Access © will be used for the transmittal and tracking of data. ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 17 2.10.5 Data Reduction No data reduction will be completed as part of this project. Third parties may reduce the data in the future for analysis and modeling. 2.10.6 Data Analysis The data may be subjected to various statistical analysis and/or modeling supporting risk analysis. In general, minimum, maximum, means, standard deviations, confidence intervals correlation with water levels, etc. may be generated. The specific statistical and/or modeling program used will be determined by the project and a full description will be documented in the final report. 2.10.7 Data Tracking This project will use Microsoft Excel © or Access © to track sample numbers and forms. 2.10.8 Data Storage and Retrieval The data will be stored in electronic form as a Microsoft Excel © or Access © document. In addition, hard copies will be available upon request. Section 3.0 Assessment and Oversight 3.1 Assessments and Response Actions Each site-specific QAPP will describe the required assessment and response actions to ensure compliance with Master QAPP requirements. Inspections will consist of, as appropriate, an evaluation of QA/QC procedures and the effectiveness of their implementation, an evaluation of work areas and activities, and a review of project documentation, to verify compliance with QAPP requirements. Additional inspection items may be added, as necessary per each site-specific QAPP, to the inspection plans by the consultant Project Manager, Environmental Scientist, or the City. Field operations assessments by the Environmental Scientist or designee may include evaluating the availability of appropriate and approved procedures; implementation of sampling procedures; calibration and operation of equipment; labeling, packaging, storage and delivery of samples; and documentation of deviations from the QAPP and nonconformance. All inspection findings that are not resolved during the course of the assessment affecting the overall quality of the project, regardless of when they are resolved, will be discussed immediately with the Project Manager. The Project Manager will ensure the necessary corrective actions are initiated and completed. 3.2 Reports to Management The data from the Phase II ESA sampling events will be made available to the City, IDEQ, and USEPA. An environmental assessment report will be prepared and delivered to the City, IDEQ, and USEPA. The report will describe sampling procedures and provide pictures and figures of ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 18 sampling locations. The report will discuss analytical precision, accuracy, representativeness, comparability, completeness, and sensitivity, and whether the analytical data meet the project DQOs.

Site personnel are trained in hazard recognition and will use personal protective equipment (PPE) appropriate to the potential hazards. a) Air Monitoring Direct read air monitoring equipment may be employed to screen for contaminants and toxic or flammable atmospheres prior to collecting samples if the project manager, or site supervisor, deems it appropriate. b) General Safety Hazards Sampling at the proposed sites will be unlikely to pose any unanticipated safety hazard to workers. The proposed scheme involves subsurface water sampling. Site investigators should be safety trained per site-specific Health and Safety Plans, and able to identify site hazards during site investigations. ---PAGE BREAK--- Because bore holes are not anticipated to be larger than 6 inches in diameter, there is no trenching or confined space hazard. If sampling will be performed along roads and alleys personnel will don “OSHA Orange” vests and traffic control measures will be initiated. The site supervisor will identify any site-specific hazards during pre-job safety meetings. The site supervisor will update employees if site hazards change. The most likely hazards to be encountered are those commonly encountered on many work-sites (heat stress, working around machinery, noise, etc.). All employees performing field work on this project will comply with the most current Health and Safety Manual and Health and Safety Standard Operating Procedures for their company. Each employee should be provided access to this manual. Article III. Work Practices Workers will comply with all Health and Safety Manual rules. Workers will comply with all state and federal regulations. PERSONAL PROTECTIVE EQUIPMENT The following Personal Protective Equipment (PPE) may be necessary:  A Class A, B, or C hard hat as appropriate to the site,  Steel-toed, steel shank work boots,  Hearing protection, and  Safety Glasses. DECONTAMINATION PROCEDURES a) Personnel: Before leaving the sample area, thoroughly wash hands and face with soap and water before eating, drinking, or smoking. If water is not available use pre-moistened towelettes to wash face and hands. Do not track contaminated soils and dust off-site. b) Samples After the sample containers are filled they will be sealed shut, marked with indelible marker, and any excess dirt will be wiped from the outside of the sample containers before they are stored. Sample containers will be transported in suitable sealed containers placed in stable containers that can be securely closed. c) Disposal of Materials Generated On-Site Collect trash and non-hazardous waste and place it in appropriate trash receptacles for municipal trash pick up. Potentially contaminated materials will be separated, sealed in chemically compatible containers, and labeled for appropriate off-site disposal. d) Safety Equipment and Materials Each sampling team will have access to a first aid kit, clean water, paper cups, and pre- moistened towelettes. Site supervisors will ensure appropriate safety gear is available for site ---PAGE BREAK--- operations. The site supervisor will also be equipped with a cell phone in case of an emergency requiring outside assistance. Article IV. Emergency Procedures If an injury occurs, take the following steps:  Prevent further injury and notify the site supervisor.  Initiate first aid and get medical attention for the injured person immediately.  Depending on the type and severity of the injury, call for medical attention.  Prepare an incident report.  The crew chief / site safety officer will assume charge during a medical emergency. a) Local Emergency Phone Numbers Ambulance: 911 Hospital: Gritman Medical Center (208) 882-4511(non-emergency) 700 S.

Label all sample containers with indelible ink (on the side, not on the cap or lid). Place labeled sample bottles in a high quality cooler containing an adequate amount of ice and/or frozen blue ice (appropriate for the season), making sure the cooler drain plug is taped shut. 2. Place the samples in an upright position and wrap the samples with absorbent, cushioning material for stability during transport. Samples should not be loose; the cooler should be able to withstand rough handling during shipment without sample breakage. 3. Fill out the appropriate shipping forms, and place the paperwork in a ziploc bag and tape it to the inside lid of the shipping container. Shipping forms usually include: 1) a chain-of-custody form, documenting the samples included in the shipment; 2) an analysis request form, specifying the laboratory analyses for each sample. If more than one cooler is used per chain of custody, put a photocopy in the other coolers and mark them as a copy. 4. Close and seal the cooler using fiberglass strapping tape. 5. Secure the shipping label with address, phone number, and return address clearly visible. SHIPPING HAZARDOUS MATERIALS/WASTE: Hazardous materials need to be shipped using procedures specified under Federal Law. Samples need to be shipped in ziploc bags or paint cans depending on the level of hazard. Special package labeling may be needed. Consult the project manager for specific shipping procedures. ---PAGE BREAK--- Updated 2008 SOP-10 Page 1 of 1 STANDARD OPERATING PROCEDURE FIELD FORMS All pertinent field investigations and sampling information shall be recorded on a field form during each day of the field effort and at each sample site. The field crew leader shall be responsible for ensuring that sufficient detail is recorded on the field forms. No general rules can specify the extent of information that must be entered on the field form. However, field forms shall contain sufficient information so that someone can reconstruct all field activity without relying on the memory of the field crew. All entries shall be made in indelible ink weather conditions permitting. Each day's or site's entries will be initialed and dated at the end by the author. At a minimum, entries on the field sheet or in field notebook shall include: · Date and time of starting work and weather conditions. · Names of field crew leader and team members · Project name and type · Description of site conditions and any unusual circumstances. · Location of sample site, including map reference, if relevant · Equipment ID numbers · Details of actual work effort, particularly any deviations from the field work plan or standard operating procedures · Field observations · Any field measurements made pH) For sampling efforts, specific details for each sample should be recorded using Maxim Technologies standardized field forms. Surface water and groundwater field forms contain fill-in-the-blank type information in order that all pertinent information shall be recorded. In addition to the items listed above, the following information is recorded on field forms during sampling efforts: · Time and date samples were collected · Number and type (natural, duplicate, QA/QC) of samples collected · Analysis requested · Sampling method, particularly deviations from standard operating procedures Strict custody procedures shall be maintained with the field forms. Field forms shall remain with the field team at all times, while being used in the field. Upon completion of the field effort, photocopies of the original field forms will be made and used as working documents; original field forms shall be filed in an appropriately secure manner. ---PAGE BREAK--- Updated 2008 SOP-11 Page 1 of 1 STANDARD OPERATING PROCEDURE EQUIPMENT DECONTAMINATION The purpose of this section is to describe general decontamination procedures for field equipment in contact with mine/mill tailings, soil, or water. During field sampling activities, sampling equipment will become contaminated after it is used. Sampling equipment must be decontaminated between sample collection points if it is not disposable. Field personnel must wear disposable latex or vinyl gloves while decontaminating equipment at the project site. Change gloves between every sample. Every precaution must be taken by personnel to prevent contaminating themselves with the wash water and rinse water used in the decontamination process. Table A-1 lists equipment and liquids necessary to decontaminate field equipment. The following should be done in order to complete thorough decontamination: 1. Set up the decontamination zone upwind from the sampling area to reduce the chances of windborne contamination. 2. Visually inspect sampling equipment for contamination; use stiff brush to remove visible material. 3. The general decontamination sequence for field equipment includes: wash with Liquinox or an equivalent degreasing detergent; deionized water rinse; deionized water rinse; rinse with sample water three times. 4. Rinse equipment with methanol in place of the nitric rinse if sampling for organic contamination. Follow with a deionized water rinse. 5. Decontaminated equipment that is to be used for sampling organics should be wrapped in aluminum foil if not used immediately. 6. Clean the outside of sample container after filling sample container. Alternatively, field equipment can be decontaminated by steam cleaning and rinsing with deionized water. All disposable items paper towels, latex gloves) should be deposited into a garbage bag and disposed of in a proper manner. Contaminated wash water does not have to be collected, under most circumstances. If vehicles used during sampling become contaminated, wash both inside and outside as necessary. TABLE A-1. EQUIPMENT LIST FOR DECONTAMINATION 5-gallon plastic tubs Liquinox (soap) 5-gallon plastic water-container Hard bristle brushes 5-gallon carboy DI water Garbage bags 1-gallon cube of 10% HNO3 Latex gloves 1-gallon container or spray bottle of Squeeze bottles 10% Methanol or pesticide grade Paper Towels acetone for organics ---PAGE BREAK--- Updated 2008 SOP-12 Page 1 of 1 STANDARD OPERATING PROCEDURE SAMPLE DOCUMENTATION Sample documentation is an important step to ensure the laboratory, project manager, and field personnel are informed on the status of field samples. Depending on the specifics required for each project, a number of forms will need to be filled out. Most sample documentation forms are preprinted carbonless triplicates, enabling copies to be filed or mailed from labs or offices. The forms will be completed by field personnel, who have custody of the samples. The office copy will be kept in the project file and subsequent copies sent to the laboratory, or other designated parties. The responsibility for the completion of these forms will be with each field crew leader. It is important the field crew leader is certain field personnel are familiar with the completion process for filling out forms, and the expected information is included. Potential documents to be completed clearly in ink for each sample generated include: · Field Form · Chain-of-Custody · Custody Seal If working on Superfund activities, the following additional forms will also be prepared: · EPA Sample Tags · SAS Packing Lists · Sample Identification Matrix Forms · Organic Traffic Report (if applicable) · Inorganic Traffic Report (if applicable) ---PAGE BREAK--- SOP-13 Page 1 of 1 STANDARD OPERATING PROCEDURE QC SAMPLES Quality Control (QC) samples are submitted along with natural samples to provide supporting laboratory data to validate laboratory results. QC samples are submitted blind, and do not have any unique identifying codes that would enable the lab or others to bias these samples in any way. Usually, the time or sampling location is modified in a way which will separate blank and standard samples from the rest of the sample train. QC samples are identified only on field forms and in field notebooks. The following codes are typically used: N - Natural Sample Soil, water, air, or other of interest material from a field site SP - Split Sample A portion of a natural sample collected for independent analysis; used in calculating laboratory precision D - Duplicate Sample Two samples taken from the same media under similar conditions; also used to calculate precision FB - Field Blank Deionized water collected in sample bottle; used to detect contamination sampling containers FEB – Field Equipment Blank Deionized water run through decontaminated equipment and analyzed for Blank residual contamination and deionized water contamination BFS - Blind Field Standard Certified materials of known concentration; used to determine laboratory accuracy TB - Travel or Trip Blank Inert material (deionized water or diatomaceous earth) included in sample cooler; sent by the lab, the sample is used to determine if contamination by volatiles is present during collection or shipping In general, selected QC samples will be inserted into the sample train. Unless otherwise specified, QC samples will be prepared in the field. Deionized water blanks will be collected from carboys and cubitainers used in the field. An exception to field preparation of QC samples is the preparation of some blind field standards. Since the concentration of analytes in the sample is to be mixed according to specific manufacturer's instructions, field conditions may not provide the needed laboratory atmosphere. This is especially true for volatile organic compounds, which need to be prepared just before analyzing. Under these circumstances, standards will be shipped to the laboratory for preparation, keeping the concentration or manufacturer's QC Lot Number as blind as possible. The number and types of samples submitted for each group of natural samples will be determined by the project manager and others, including state or Federal agencies, and will be defined in the project work plan. Each field crew leader will be responsible for all QC samples prepared by that crew. Methods for computing data validation statements can be found in EPA documents. ---PAGE BREAK--- Updated 2008 SOP-16 Page 1 of 1 STANDARD OPERATING PROCEDURE MONITORING WELL CONSTRUCTION 1. Arrive on-site with properly sized drilling equipment and materials for site conditions. All drilling equipment and materials should be properly decontaminated prior to its arrival on-site. Decontamination usually includes steam - or hot water-cleaning methods. 2. Drilling muds or drilling solutions of any kind are not to be used during drilling activities in conjunction with monitoring well construction. Acceptable drilling techniques include air-rotary, cable tool, or hollow-stem auger. If unconsolidated material is encountered, it may be necessary to drive steel casing during drilling to maintain borehole integrity. It is suggested threaded steel casing be used in lieu of welding joints together to minimize this source of potential well contamination. Hydraulic jacks or the drill rig can be used to pull back the steel casing following emplacement of plastic casing. 3. A detailed lithologic log shall be completed during drilling activities. Water bearing characteristics of the formations should also be denoted on the log. In addition, details of monitoring well construction should also be described on the well log including total depth, perforated interval, sizes and types of construction materials, etc. 4. Eight- or ten-inch outside diameter hollow-stem augers can be used in drilling shallow exploration drill holes in many situations. Care should be taken to avoid contamination due to oil and grease from the drill rig and split spoon sampler. Appropriate decontamination of the drill rig between drill holes is performed. Soil and sediment samples are collected using a standard 1.4-inch inside diameter split spoon sampler and a 140-pound drive hammer. The number of blows necessary to obtain an 18-inch length of sample is recorded on the exploration log. Appropriate decontamination of the split spoon sampler is accomplished between samples. Either a single- or multi-completion monitoring well can be constructed in a single borehole where hollow-stem auger drilling is not used. Backfill with chemically-inert silica sand to above the perforated interval and emplace a bentonite plug above the sand. Install factory-screened and blank PVC (or stainless steel or PTFE for organics) well casing into the borehole. Where appropriate, begin pulling temporary steel casing out of borehole. Emplace silica sand above and below any perforated sections in the borehole; install bentonite plugs above and below sand pack around perforated sections. Backfill remaining well annulus with a bentonite slurry or with grout to the surface. Monitoring well development is presented in SOP-17. 5. Place locking well steel protector over PVC casing(s) after outer steel casing has been removed from the borehole if necessary. Place bentonite plug below bottom of well protector; grout well protector in place and lock with high quality lock. 6. Many states now require certification and licensing for monitoring well drillers. Be sure you know the State's regulations before arriving on-site, especially if drilling outside your own State. 7. Safety equipment required on-site of the drill rig is mandatory. Personal protective equipment includes (at a minimum): hard hat, safety glasses, steel toed boots, gloves, first aid kit, and site safety plan - with routes to hospitals known by all personnel on-site. ---PAGE BREAK--- Updated 2008 SOP-17 Page 1 of 1 STANDARD OPERATING PROCEDURE MONITORING WELL DEVELOPMENT 1. Visually inspect all well development equipment for damage - repair as necessary. 2. Decontaminate all stingers, air hoses, surge blocks by scrubbing with brush and Liquinox solution, rinsing with dilute nitric acid solution, and rinsing with deionized water. If sampling for organics, replace the nitric acid rinse with 10% methanol as per SOP 11. 3. If using compressed air method for well development, make certain compressor utilized does not produce air laden with hydraulic fluid for lubricating purposes. This may affect the integrity of the monitoring well for producing viable water quality data. 4. Develop well by using surging techniques (surge block or bailer) followed by well evacuation. Repeat this procedure until evacuated water is visibly clean and essentially sand-free. In most cases, evacuated water can be disposed of on-site. 5. If specified in the project work plan, during evacuation process, collect water samples for field determinations of temperature, specific conductivity, and pH. Continue developing well until field parameters stabilize to within ±5 % on three consecutive measurements. 6. Report field observations and volume of water removed on standard form. ---PAGE BREAK--- Updated 2008 SOP-20 Page 1 of 1 STANDARD OPERATING PROCEDURE FIELD MEASUREMENT OF GROUND WATER LEVEL 1. Well probe should be calibrated annually or as needed. Note any corrections to well probe measurements on field forms. 2. Check well probe prior to leaving for field for defects by placing probe in water and testing buzzer and light. Repair as necessary. Make certain the well probe, a tape measure calibrated to tenths of feet and extra batteries are in the carrying case. 3. Measure all wells (monitoring and domestic) from the top of the well casing in the north quadrant or from a designated measuring point, as appropriate. Measure and record distance from measuring point to ground level. Make sure measuring point is labeled on well, so future measurements can be made from the same location. 4. Obtain a depth to water from measuring point to the nearest hundredth of a foot. Record data on appropriate field forms. 5. Decontaminate well probe between each measurement by rinsing with deionized water. Additional decontamination, such as Liquinox" scrubbing, may be required for certain wells; consult the project work plan. ---PAGE BREAK--- SOP-22 Page 1 of 3 STANDARD OPERATING PROCEDURE DRILLING SOIL SAMPLE COLLECTION This SOP describes the field equipment and sampling methods for surface and subsurface soil sample collection using drilling methods. FIELD EQUIPMENT: Tape measure Stainless steel trowel or putty knife Munsel soil color book (if required) Grain size chart (as needed) Field forms and field book Hand auger PROCEDURE: Clear Utilities 1. Hand auger to clear buried utilities identified as being near the excavation location or if unsure of the presence of buried utilities. 2. As an alternate, contract with a vacuum truck subcontractor to clear utilities prior to excavation work. Direct-Push Technology (a.k.a. Geoprobe) 1. Ensure drilling contractor will provide (PVC) or similar sample core tubes. 2. Driller will collect core of sample with the tubes. 3. Set up table in work area for cores or use pickup tailgate. 4. Cut core tubing using specialized cutting tool. 5. Measure and record the amount of soil recovery in the core with the tape measure. Record the estimated depth interval of sample collection. 6. Log the lithology encountered in each core. Estimate the depth of changes in lithology by using tape measure. Document elements such as grain size, rock type, moisture, color, staining, and odor. If debris or fill is encountered, document the depth and type of debris or fill. Document the depth to the approximate air-water interface, if encountered, along with any special characteristics observed at or near the saturated zone (capillary staining, change in lithology, etc.). 7. If performing on-site soil screening with PID or FID and heated headspace analysis (SOP- 27), or other on-site screening method. Document the sample screening interval, characteristics of the interval, and the concentration measured with the PID, FID, or other screening method. ---PAGE BREAK--- Page 2 of 3 8. Collect soil samples from select intervals, as per sampling and analysis or work plan. Document the approximate depth of the sample collection interval and any observations specific to the interval (e.g. soil characteristics, staining, odor, etc.). 9. Containerize the sample in appropriate laboratory-provided sample jars. Place samples immediately in a cooler containing doubled re-sealable bags filled with ice. 10. Preserve remaining core material (as needed or required), or containerize the soil for proper disposal. Hollow-Stem Auger Drilling 1. Ensure drilling contractor will provide split-spoon sampler will be provided by driller. Stainless steel, polycarbonate, or other liners for the sampler may be required (consult the sampling and analysis plan or work plan). If performing geotechnical sampling, the driller will also need to ensure a 140-pound hammer will be used for sample collection. 2. Driller will drill to starting point for sample collection. The sampler will be driven ahead of the augers and a sample collected from the “undisturbed” soil. 3. Record the driller’s blow count for the driven sample. 3. Set up table in work area for cores or use pickup tailgate. 4. Open the split spoon using proper tool (e.g. pipe wrenches) and vice to reduce strain on hands and wrists. Open sampler from the end using a pry bar or similar. 5. Measure and record the amount of soil recovery in the sampler with the tape measure. Record the estimated depth interval of sample collection. 6. Log the lithology encountered in each core. Estimate the depth of changes in lithology by using tape measure. Document elements such as grain size, rock type, moisture, color, staining, and odor. If debris or fill is encountered, document the depth and type of debris or fill. Document the depth to the approximate air-water interface, if encountered, along with any special characteristics observed at or near the saturated zone (capillary staining, change in lithology, etc.). 7. If performing on-site soil screening with PID or FID and heated headspace analysis (SOP- 27), or other on-site screening method. Document the sample screening interval, characteristics of the interval, and the concentration measured with the PID, FID, or other screening method. 8. Collect soil samples from select intervals, as per sampling and analysis or work plan. Document the approximate depth of the sample collection interval and any observations specific to the interval (e.g. soil characteristics, staining, odor, etc.). 9. Containerize the sample in appropriate laboratory-provided sample jars. Place samples immediately in a cooler containing doubled re-sealable bags filled with ice. ---PAGE BREAK--- Page 3 of 3 10. Preserve remaining sample material (as needed or required), or containerize the soil for proper disposal. ---PAGE BREAK--- SOP-24 Page 1 of 1 STANDARD OPERATING PROCEDURE SOIL SAMPLE PREPARATION AND PRESERVATION The Field Project Supervisor (FPS) will direct all packaging and shipping procedures in the field. PROCEDURE: 1. All natural soil samples, QA/QC samples and sample splits will be documented on field forms/notebooks and tracked via chain-of-custody. 2. At the time of sample collection, field personnel will write affix a sample label(s) to each sample container corresponding to the sample being collected. At a minimum, the sample location number, date, and time will be written on the label in indelible ink. 3. The soil samples will then be immediately placed into a cooler containing doubled re- sealable plastic bags filled with ice for preservation. The ice will be replenished as necessary and prior to shipping to ensure proper temperature control for preservation B+ 3 1 - 7 ; 61 = "A 466". 1 - / 5 1 0 = 48 2 ? . . 61 "A ; - <0 . 9 - <0 "0 4@ 40 1 "9 >3 1 suitable stabilizing materials to prevent breakage of the sample containers during shipping. 4. One (or more if necessary) chain-of-custody documents which samples are contained within the cooler. Each transfer of the cooler to personnel, shipping couriers, and the laboratory will be documented on the chain-of-custody. 6. The FSP will check the samples in the cooler against the chain-of-custody to ensure all samples are properly documented and accounted for prior to shipment to the laboratory. 9. Once the samples are verified on the chain-of-custody, the cooler will be sealed with shipping tape, custody seals will be affixed over the opening of the cooler (one on the front and one on the back), and the air bill affixed to the cooler. 10. During the sample collection and shipment process, sample coolers will be kept in a secure location and temporary custody seals applied to the cooler when not in the direct presence of field personnel. ---PAGE BREAK--- Updated 2008 SOP-27 Page 1 of 2 STANDARD OPERATING PROCEDURE FIELD MEASUREMENT OF VOLATILE ORGANIC COMPOUNDS HEADSPACE INSTRUMENT CALIBRATION: 1. Calibrate meter before leaving for the field and each day in the field when headspace will be measured. Calibrate using one of the following procedures: A. HNU (PID) · Connect probe to the body of the instrument and turn selector switch to desired sensitivity range (typically 0-200) · Zero instrument and connect span gas. · Adjust span setting to read appropriate concentration for gas type and photoionization bulb. B. Photovac Microtip (PID) · Assemble instrument and turn on. · Press calibrate button and follow instructions as they appear on the screen. C. Photovac 2020 (PID) · Assemble instrument and turn on. · Press set button and follow instructions as they appear on the screen. D. Foxboro OVA (FID) · Assemble instrument, open H2 supply valves, put operation and pump toggle switches to "on" position. · Allow to run for 3-5 minutes and push in the ignition button for 1/2 second. Check unit with span gas or known volatile to assure instrument is operating. FIELD PROCEDURES: 1. Place sample to be tested in clean canning type jar. Cover the sample using aluminum foil and the outer ring of the jar lid. Alternately, a new ziploc bag maybe used. Be sure to mark container with sample location (boring/test pit # and depth)! 2. Allow sample to come to room temperature (approximately 70 - 80 by placing in warm location not in direct sunlight. This can be accomplished by placing the container under the heater vent of the vehicle in winter or in a closed vehicle in summer. ---PAGE BREAK--- Updated 2008 SOP-27 Page 2 of 2 3. Insert probe through foil or ziploc opening and record maximum reading. NOTE: Consistency in results is enhanced by using approximately equal portions of material, similar jar or bag sizes and similar test temperatures. Moisture content may also affect readings using some instruments. MAINTENANCE: 1. Disassemble and store meters in their case. 2. Charge batteries after each use as described in user's manual. 3. Occasional routine maintenance may be necessary ie. cleaning or replacing filters. Any maintenance you feel unqualified to perform should be handled by an authorized service representative. ---PAGE BREAK--- Updated 2008 SOP-44 Page 1 of 2 STANDARD OPERATING PROCEDURE IONIZATION DEVICE (PID or FID) OPERATION 1. Before taking the instrument to the field, check the following: · Test the condition of the battery and recharge if necessary. · Make sure you have calibration gas. · If you are using the FID, check the hydrogen pressure and refill from the supply bottle if below 1000 psi. · Check the integrity of the instrument and its accessories. Repair or replace broken parts and clean the sampling tip. On the PID clean the inlet filter. · Make sure you have all the accessories you will need for sampling. 2. Arrive on-site with decontaminated equipment in working order. During transport, keep the instrument temperature stable and moderate. 3. Follow the manufacturer's instructions for starting up the instrument. Turn the instrument on and let it run for a few minutes, allowing the electronics to stabilize. 4. For the FID, let the electronics warm up for about 5 minutes and the pump to run for at least 3 minutes before attempting to light the flame. After lighting the flame, test the instrument with a known hydrocarbon to make sure the flame remains lit. 5. Calibrate the instrument by setting the zero and span against the calibration gases. To zero the instrument you may use clean air, if available, or a cylinder of compressed zero gas. 6. Complete your organic vapor readings and record the results according to the SOP covering the test procedure you are using. 7. Shut down the instrument according to the manufacturer's instructions. Decontaminate and carefully pack the instrument before leaving the site. ---PAGE BREAK--- Updated 2008 SOP-44 Page 2 of 2 TABLE 1 COMPARISON OF ORGANIC VAPOR ANALYTICAL FIELD INSTRUMENTS Instrument Advantages Disadvantages Limitations Foxboro/Century OVA-128GC (FID) 1.

Material removed from the test pit will be replaced back into the test pit in the approximate same depth and location as from where it was removed, as possible. For soil borings, on-site screening visual, olfactory, PID, debris) will be used to evaluate when soil is potentially contaminated. Potentially contaminated soil will be containerized until analytical results are received from the laboratory. Soil containers will be labeled as to the site name, date, soil boring locations, and contents. If results indicate soil is does not contain concentrations of contaminants above soil screening levels, soil may be thin spread on site. If concentrations exceed one or more soil screening level, appropriate soil/waste disposal will be arranged for soil at an approve landfarm or landfill. Groundwater Groundwater purged from wells during development and sampling will either be released to the ground surface away in the area of the well if there are no indications of possible contamination (odor, sheen, etc.). If observations such as odor or sheen indicate possible contamination, water will be containerized in 55-gallon drums on site until analytical laboratory results can be reviewed and compared with groundwater standards. Water that exhibits contamination above groundwater standards will be disposed at an approved recycling or disposal facility. Any drums used for temporary containment will be labeled with the site name, date, well names, and contents.
