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 Agencyβs (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 Qualityβs (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 βthe Cityβ) 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 siteβs 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. Each site-specific QAPP will include a list or table of key personnel and responsibilities (Figure 2) which should include all subcontractors identified in the organization chart environmental laboratory, driller, experts etc.).

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: ο· Conduct site inventory and site selection activities; ο· Prepare environmental site assessments and ABCAs for selected properties; and ο· 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 Moscowβs 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. Site Location Map ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 6 1.3.2 Description of Site-Specific Assessment Activities Each site-specific QAPP will identify the specific tasks to be conducted utility and/or geophysical survey, mobilization, type(s) of sampling activities, and demobilization). 1.3.3 Project Timetable Each site-specific QAPP will identify the timeline for specific project execution. Schedule of Activities (example) ο· Site-specific QAPP, site-specific Health and Safety Plan (see Appendix A for an example Health and Safety Plan), Subcontracting, Scheduling: (include dates here) ο· Sampling Schedule: (include dates here) ο· Report Preparation: (include dates here) ο· Issue Draft Report by (include date here) 1.4 Quality Objectives and Criteria Each site-specific QAPP will identify the data quality objectives and data quality indicators associated with the assessment. 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 siteβs 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). USEPAβs 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 siteβs 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 Moscowβs 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: ο· Do some portions of the site contain contaminants above cleanup levels that would preclude residential, commercial, and/or recreational redevelopment or use? ο· Do the contaminated materials at the site have the potential to affect human health and/or the environment? ο· 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 Idahoβs 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 siteβs 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): ο¨ ο© ο¨ ο© % 100 2 2 1 2 1 ο΄ ο· οΈ οΆ ο§ ο¨ ο¦ ο« ο ο½ 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 ) ( % ο΄ ο ο½ 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-Rainο (or similar) field notebook will be used in the field to document the samplersβ 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 Cityβs contractor will contain the analytical laboratoryβs 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 Cityβs 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 Cityβs consultant will complete internal QA/QC to ensure the quality of the data. 1.6.3 Data Handling Records The Laboratoryβs 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 Cityβs 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. The site-specific QAPP will also identify the types, numbers, media, depths, methods, and sequence of samples that may be collected as part of assessment activities. Equipment used to collect the samples will be described, decontamination procedures specified, and investigation-derived waste handling and sampling will be discussed. 2.3 Sample Handling and Custody Procedures Each site-specific QAPP will identify the sample numbering system and custody procedures. However, to prevent duplication and allow future users of the data to quickly identify general sample locations by site, all sample numbers will start with the site designations S1, S2, S3, S4, or S5, as applicable. 2.3.1 Sample Numbering System Example Subsurface Soil Samples (Discrete) and Groundwater Samples (Direct Push Discrete Interval Method) from Site 1: S1- Where: S1 = Site 1 NN = boring number or location XX = type if other than subsurface soil (GW = groundwater sample) dd-dd = Depth interval (for example, 00-01 = 0- to 1-foot interval, 02-03 = 2- to 3-foot interval, 2.5-3.5 β 2.5 to 3.5 feet, etc.). = month day year ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 13 QAQC indicator will follow the in the sample name only if applicable: D = dup, SP = split, FB = field blank, and TB = trip blank. Groundwater Monitoring Well Samples MWS1 ID Where: MWS1 ID = existing monitoring well sample ID from Site 1 collected on date. QAQC indicator will follow the in the sample name only if applicable: D = dup, SP = split, FB = field blank, and TB = trip blank. 2.3.2 Sample Custody Each sample will be identified on a chain-of-custody record. Information recorded will include at a minimum the site name, sampler name(s), date and time of sample collection, sample identification, number of containers for each sample, analyses requested for each sample, and signature blocks for each individual who has custody of the sample(s). Samples will be submitted to the laboratory and maintained at the laboratory under chain-of-custody. Final reports, which include all original laboratory reports and chains-of-custody, will be maintained in the City consultantβs project file system. 2.4 Analytical Methods Each site-specific QAPP will identify the analytical method requirements related to the assessment samples. Samples will be analyzed for all COCs using Test Methods for Evaluating Solid Waste, Physical/Chemical Methods (SW-846) (USEPA, 2008) by an off-site analytical laboratory. Sample analysis will be in accordance with approved USEPA analytical methods (see Table 1 for Techniques, Method Numbers, and Reporting Limits for Analysis). Reporting limits for soil and groundwater will meet or be less than the IDEQ REM IDTLs (IDEQ, 2004) and/or IDEQ petroleum rule RUSLs (IDEQ, 2011). Reporting limits for indoor air will meet or be less than the USEPA RSLs (USEPA, 2011) for residential air. Reporting limits for soil vapor (vapor intrusion pathway) for subslab and deep will meet or be less than 10 times and 100 times the USEPA RSLs (USEPA, 2011) for residential air, respectively. ---PAGE BREAK--- Master QAPP for the City of Moscow Brownfields Phase II Environmental Site Assessments 14 Table 1.

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 USEPAβs 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).
