Site Characterization Work Plan 1322.05, Kodiak Island Borough 1.0 INTRODUCTION Page 4 January 2017 The Kodiak island Borough, (KB) contracted Travis/Peterson Environmental Consulting, Inc. (TPECI) to develop a site characterization plan to investigate contaminated soils at the Karluk School (hereinafter: school) and school generator building. In August 2013, KB closed four registered underground storage tanks (UST) in-place. Closure activities found petroleum (heating oil) contamination in subsurface soils. The goal of this site characterization plan is to provide the KB and Alaska Department of Environmental Conservation (ADEC) with information regarding the vertical and horizontal extent of contamination at this site. The plan consists of the following: • Soil borings; • Screening and collecting soil samples; • Standard operating procedures; • Coordination with the ADEC; and • Documenting and reporting requirements. 1.1 SITE DESCRIPTION AND BACKGROUND l.l.l Location The property is located in Karluk, Alaska within Section 21, Township 30 South, Range 32 West at the Seward Meridian and within US Geological Survey Quadrangle Karluk C-2. Figure I is a vicinity map showing the site location within the region. The primary area of concern is located on K1B property to the north and east of the school (Figure 2). The physical address for the school is: Main Street, Karluk, AK 99608. The latitude and longitude coordinates are: 57.56270278°N, -154.43666667"W. 1.1.2 Geology and Ilydrology Alaska Resources and Environmental Services (ARES) documented the UST decommission process at this site in a report dated September 2013. In the report, ARES noted that the observed soil types at the site consisted primarily of silt and poorly graded sandy and silty gravels (ML, SM, and GM classification). Permafrost is not present at the site. The school is located approximately 750 -ft south of Karluk Lagoon at 110 -ft elevation. Karluk Lagoon is the primary hydrological feature in the immediate area. The lagoon is a marine water passage wherein the Karluk River flows to the Shelikof Strait. Light boat traffic is present in the lagoon during the summer. The waters of Shelikof Strait flow into the Gulf of Alaska. Groundwater is approximately the elevation of the Karluk River. 1.1.3 Proper0, Histor3 The school, generator building, and area of concern are located in Tract F of the Karluk Subdivision (Plat No. 82-13). The property is approximately 5.4 acres in area and has been owned by the KIB since September of 1982. The generator building is a small single story structure (14 -ft x 26 -ft). The school consists of a single story, timber frame building (95 -ft x 10041). Both structures are located in the northern half of the property. No other buildings are on site.

DOUN[J11NY 5 /� 7 L. Site Characterization Work Plan Page 7 1322-05, Kodiak Island Borough January 2017 Two 12,000 -gallon USTs and two 500 -gallon USTs were closed in-place by Red Hook Construction at this location in August 2013 (ARES, 2013). All USTs were single-wall steel construction and approximately 30 -years old. In the winter of 2012-2013, school maintenance personnel discovered a leak at a fuel pipe. According to the statement, approximately 100 -gallons of heating oil leaked into subsurface soils (ARES, 2013). Following the UST decommission process, ARES collected 24 analytical soil samples to verify final site conditions. All but one sample were collected around the tanks and associated fuel lines. Maximum excavation depth was I 1 -ft bgs. Eleven samples contained elevated levels of diesel range organics (DRO). The highest concentration of DRO was 7,210 mg/kg. Two samples contained high levels of benzene. One sample contained gasoline range organics (GRO) above the ADEC cleanup level. Polycyclic aromatic hydrocarbons (PAH) were not detected. Sample analysis indicates that contamination is present in subsurface soils surrounding the four USTs and associated pipe. In 2013, a double-wall, 8,000 -gallon aboveground storage tank (AST) was installed on a gravel pad next to the school (Figure 2). All associated fuel lines are above ground. A 6" PVC water line runs across the northwest portion of the property. This water line connects the community of Karluk with a drinking water storage tank located approximately 1,000 -ft southwest of the school at an elevation of 185 -ft. The tank stores Karluk's drinking water. The drinking water originates from hillside drainage seeps upgradient of the water lank. 1.1.4 Surrounding Uses Downgradient property use is commercial and residential in nature. The Karluk Tribal Council garage, water pump house, and power generator are located immediately downgradienl of the school property. The Karluk Subdivision located just beyond the garage and pump house contains the majority of the community's residences. Property upgradient of the site is vacant land. There are no active ADEC- identified contaminated sites within the vicinity. 2.0 SAMPLING AND ANALYSIS PLAN The KIB requested TPECI to complete a site characterization work plan that pmvides details for determining the extent of soil contamination at this site. This section explains this process with a work plan design and rationale. 2.1 WORK PLAN DESIGN AND RATIONALE TPECI designed this site characterization plan to delineate the horizontal and vertical extent of possible petroleum contamination in subsurface soils surrounding the four decommissioned USTs and the generator building. TPECI will use a mobile gas -powered MinutemaffM drill rig to advance soil borings at multiple locations throughout the area of concern. Drill rig auger flights will be replaced with a split spoon sampler in order to facilitate both screening sample and laboratory sample collection. As further described below, samples will be systematically collected from borings at specific depths. All soil borings will be drilled within the KIB property. TPECI will ensure that the soil sampling will be conducted in accordance with this ADEC-approved plan. Results from this site characterization will determine how remedial action and soil treatment or disposal is initialed. Travis/Petemon Environmental Consulting, Inc. Site Characterization Work Plan Page 8 1322.05, Kodiak Island Borough January 2017 2.2 PROJECT FOOTPRINT The project site encompasses approximately 0.5 acres. This estimate is based on site limitations such as the local topography, drill rig access, and previous soil sample results at this location (ARES 2013). Other project site limitations include the school's linear utilities, which include electrical, water, and sewer line (Figure 2). 2.3 CONTAMINANTS OF POTENTIAL CONCERN Contaminations of potential concern (COPC) were determined using Table 2A of the ADEC Underground Storage Tank Procedures Manual for #1 Diesel (heating oil). TPECI personnel will test soil for DRO, GRO, and benzene, toluene, ethylbenzene, and xylenes (BTEX) with 10% of samples tested for PAH. Average annual precipitation at the closest climate station (#505425) is 22.06 inches, therefore cleanup level goals for the COPC fall under Method Two Migration to Groundwater Cleanup levels for the Under40-Inch Zone as listed in Table B2 in 18 Alaska Administrative Code (AAC) 75.341. 2.4 SCREENING AND SAMPLING All sampling will be conducted in accordance with 18 AAC 75 and the ADEC March 2016 Field Sampling Guidance. 2.4.1 Proposed Soil Screening and Laboratory Sampling The site characterization will investigate the extent of contamination within soils upgradient and downgradient of the generator building. TPECI will expand soil screening efforts to determine the size and depth of contamination if additional contamination is found outside of this area. To identify and characterize the potential contamination, TPECI will use a MinutemanTM drill rig to drill between 8 and 10 soil borings at the site. Figure 3 shows the approximate location that TPECI intends to drill soil borings. The proposed soil boring locations are based on sample results summarized in the 2013 ARES report, topography, and groundwater gradient. Soil borings will be drilled to a depth of 20 -ft or to refusal, whichever comes first. TPECI believes a 20-0 deep soil boring is adequate for vertical characterization due to sample results from ARES test pits in 2013. Samples containing the highest concentrations of DRO were collected between 1 and 6 feet bgs. According to the ARES report, one of three samples collected at a maximum depth of 11 -ft bgs contained DRO at 236 mg/kg. Thus, petroleum contamination is not likely present in soils beyond 20 -fl bgs. However, drilling will continue if contamination is discovered in soils collected at 20-11 bgs. Heated headspace screening samples will becollected from a split spoon sampler using procedures outlined in the ADEC March 2016 Field Sampling Guidance. Samples will be collected at five foot intervals within each soil boring. TPECI will screen soils using a photo -ionization detector (PID). The PID will detect volatile organic compounds (VOC) in parts per million (pptn). TPECI will use a PID threshold of 20 ppm to determine if soils exhibit petroleum contamination in excess of ADEC Method Two Migration to Groundwater cleanup levels (Under40-inch Zone). TPECI will collect laboratory samples from areas where soil screening samples exceed the 20 ppm VOC threshold. In addition to this, TPECI will collect a single soil sample from each boring determined by the headspace screening process to be less than 20 ppm VOCs. This additional sample will confirm whether the contamination boundary has been reached vertically.

Laboratory samples will be tested for the COPC as described in Section 2.3. Both screening samples and laboratory samples will be collected using methods outlined in the ADEC A4arch 30/6 Field Sampling Guidance. These methods are outlined in detail in the following section. 3.0 STANDARD OPERATING PROCEDURES The standard operating procedures (SOP) for this project fall into two categories, field SOP and laboratory SOP. Throughout the sampling effort, laboratory hold -times and sample temperatures shall be maintained. The SOP contained herein refer to generic field sampling and sample preparation. 3.1 FIELD SOP The PID will be calibrated according to the manufacturer's specifications before traveling to the site. Isobutylene calibration span gas (100 -ppm) will be used to calibrate the PID. The PID will be calibrated before departure to the field because of Federal Aviation Administration regulations associated with the shipping and handling of compressed gas. Screening samples will be collected using a PID, to screen potentially contaminated soils. The hand-held PID will be used to identify contaminant concentrations using the heated beadspace method in a scalable plastic bag. Rocks will be removed from samples as necessary using a sieve. Sealable plastic (Ziplock®) quart -sized bags will be filled half full. The soil, sealed in a plastic bag, will be shaken for 15 -seconds and then allowed to warm up for at least 10 -minutes (but not more than 1 hour) to between 500 and 700 Fahrenheit. The sealed bag will be shaken again for 15 -seconds. The PID intake nozzle will then be placed inside the bag for 10 -seconds and the highest reading will be recorded. 3.2 LABORATORY SOP Field personnel shall keep detailed notes that include: • Project Name; • Date; • Weather conditions, site conditions, other observations; Tmvis/Peterson Environmental Consulting, Inc. Site Characterization Work Plan 1322-05, Kodink Island Borough • Sample collection date and time; • Sample identification number; and • Sampling methodology. Sampling location plan view: • Sampling location cross-sectional view (if applicable); • Unusual characteristics of the sampling location; and • Any problems encountered during sampling. Page 1 I January 2017 Field notes will be collected in an all-weather notebook. The notebook utilized will not be dedicated solely to this project, but only information relevant to the project will be included on pages assigned. Combined project field notebooks reduce project costs and minimize waste generation. Field notes will be written in pen, pencil, or water-resistant marker. When field conditions result in illegible content due to dirt, precipitation, or poor penmanship, field notes will be recopied immediately after field activities. 31.1 Field Sample Preparation SOP All samples will be prepared in accordance with laboratory instructions. At a minimum, the following information will be included on the sample label: • Client name; • Date and time of sample collection; • Sampler; • Sample location; • Preservative, and • Analytical test(s) to be run. In addition, the above information will be recorded in the field notes. Chain of custody records will be maintained for each sample. Samples will be kept between zero (0) and six (6) degrees centigrade (°C). The Field technician will place custody seals on all coolers to determine if the samples may have been tampered while being transported to the laboratory. The laboratory will notify TPECI in such an event so that a decision can be made on whether or not re -sampling is necessary. All laboratory soil samples will be analyzed for GRO compounds by method AKI01, BTEX by EPA Method 8021B, and DRO by method AK102. One sample for every 10 laboratory samples will also be analyzed for PAH using EPA Method 8270D to comply with ADEC's requirement of 100/n+ sampling of PAH for diesel contamination (ADEC March 2016 Field Sampling Guidance Appenrlty F).

Soil sample containers will be filled to a volume (mass) ranging from 25 to 50 -grams of soil (approximately 1/3'u container volume) and will be immediately preserved by pouring methanol over the soil and promptly securing the Teflon -lined container lid. Care will be taken to ensure soils are completed covered with preservative. Should more than 25ml of preservative be required for a given sample, documentation of total preservative volume will be recorded in the field notes. 3.1.2 Field Decontamination Procedures Field personnel will use clean disposable sampling gloves when acquiring samples. A stainless steel trowel and disposable plastic spoons will be used for the collection of samples. Prior to use and between each sampling location, reusable sampling implements will be immersed in a bucket of Alconoxe detergent cleaning solution, scrubbed, rinsed, and dried. The small volume of wash and rinse water will collected in a bucket or drum and stored on site. TPECI will use absorbent pads to remove sheen from the rinse water. Used absorbent pads will be disposed of using a SmartAsht, bumer. 3.2.3 Field and Laboratory Calibration Methods All field and laboratory procedures requiring instrument calibration will be conducted according to the applicable Environmental Protection Agency (EPA) methods, the ADEC methods, and standard operating procedures. The manufacturer calibrates the PID annually. The PID will also be calibrated with fresh air and a 100 ppm isobulylene calibration standard daily before it is used, The EPA checks the calibrations traceable quality control standards for the laboratory. 3.2.4 Routine and Periodic Quality Control Activities SGS Laboratory, an ADEC-approved laboratory, will be used for all soil samples. This section describes the methods used for determining the quality of laboratory results. 3.2.5 Field Quality Control Samples Field personnel will take two types of field quality control samples. These are sample duplicates and trip blanks. The objective and frequency of these samples are discussed below. TPECI will not collect field blanks or equipment blanks. TPECI will rely on field duplicates and trip blanks for quality control and determination of artificially introduced contamination. 3.2.5.1 Field Duplicates Field duplicates are samples collected simultaneously from the same sampling locations. Field personnel will use identical sampling methods to retrieve one duplicate for every 10 samples. TPECI will follow the some QA/QC methods for collecting, packaging, recording, and shipping the duplicate samples as all other samples. 3.2.5.2 Trip Blank Trip blanks are samples prepared from sterile media at the laboratory and shipped with the sample containers. Trip blanks remain with the samples after collection and are analyzed for volatile compounds. Tltis analysis determines if any cross -contamination occurred during shipping. Field personnel will never open the trip blank containers during the entire sampling process. Field personnel will use one trip blank per cooler. If the laboratory finds any contamination within the trip blank, the results will be used to evaluate any possible impacts to associated samples. Travis/Peterson Environmental Consulting, Inc. Site Characterization Work Plan Page 13 1322-05, Kodiak Island Borough January 2017 3.2.5.3 Field Blank TPECI will not collect field blanks for this project. The logistical challenges associated with transporting an unknown (and potentially large volume) of analyte -free (de -ionized) water to the site would result in an operational burden. 3.2.5.4 Equipment Blank TPECI will not collect equipment blanks for this project. The logistical challenges associated with transporting an unknown (and potentially large volume) of analyte -free (de -ionized) water to the site would result in an operational burden. TPECI will conduct thorough Geld decontamination procedures as described in Section 3.2.2. 3.3 LABORATORY QUALITY CONTROL. SAMPI.FS The project laboratory will use matrix -spiked samples, spiked duplicates, surrogates, method blanks, duplicates, and laboratory control samples to measure data quality. Matrix spiked samples and laboratory control samples assess sample matrix interference and analytical errors and accuracy. Surrogates evaluate accuracy of an analytical measurement. Method blanks check for laboratory contamination and instrument bias. Duplicates measure the precision of the analysis. The laboratory will use one method blank per sample period and use one laboratory control sample. The laboratory will use a surrogate spike for every sample, standard, and blank. The laboratory will use one matrix spike per sample period. 3.3.1 Data Redaction, Validation and Reporting Data reduction is conducted by the analyst. All calculations are made as specified by the particular analytical method. Units are reported as mg/L, µg/L, µg/mL or as otherwise called for in the method. Analytical data reports will include: • Client name; • Date and time of sample collection; • Sample location; • Date and time samples received at the laboratory; • Date analysis completed; • Laboratory sample ID number; • A list of parameters analyzed; • The analytical method number for each parameter; and • Concentration of each parameter. The laboratory will forward a copy of the completed analytical results to TPECI. 4.0 PROJECT SCHEDULE The KIB intends to commence the work outlined in this site characterization plan in the summer of 2017. TPECI anticipates project completion by the end of the 2017 summer season. Travis/Peterson Environmental Consulting, Inc. Site Characterization Work Plan 1322-05, Kodiak Island Borough 5.0 DELIVERABLES Page 14 January 2017 The data deliverables for the project shall include a written report summarizing field activities, results, and conclusions. The report will include or specifically address the following information: • Site investigation overview; • Laboratory results; • Field observations; • Investigation findings; • Conceptual Site Model; and, • Recommendations for future site work. 6.0 CONCLUSIONS It will be the goal of TPECI to provide the KIB and the ADEC with a comprehensive understanding of the extent of contamination present at this site. Soil samples collected from numerous soil borings at the site will provide information into the vertical and horizontal extent of the contamination. TPECI will use this information to generate a site characterization report that summarizes field activities, sample results and recommends corrective actions for site remediation. TPECI will notify the ADEC 48-hrs before mobilization. TPECI will also coordinate with the ADEC on an as -needed basis during field activities if additional guidance is needed. 7.0 REFERENCES Alaska Resources and Environmental Services (ARES, 2013), "Karluk School UST Decommissioning".

KIB entered into a contract with TPECI to do a site investigation and soil sampling at Karluk School, at the site of decommissioned underground storage tanks. Based on reports from other contractors at the site, KIB requested TPECI expand the scope of their investigation to include the old playground site, which increased the labor hours and sampling costs. It was also agreed that KIB would pay directly for the sampling costs, but due to an oversight TPECI paid for them, resulting in an increase to the contract amount. Since KIB planned to pay for these sampling costs directly, it was agreed that TPECI would only be reimbursed for the direct cost of sampling, without any additional markup. There is currently $68,000 remaining in the budget for this project, adequate funds for this change order.

(TPECI) to develop a Soil Removal and Vapor Instruction work plan for contaminated soil at Karluk School. In 2013 KIB closed in place four underground fuel tanks at the school. There is still contaminated soil remaining from when the tanks were in use. In June 2017 KIB entered into a Professional Services Agreement with TPECI to perform soil sampling mandated by the Alaska Department of Environmental Conservation (DEC). Now that samples have been taken determining the extent and level of contamination, DEC is requiring a written work plan to remove portions of the contaminated soil, as well as perform vapor instruction testing at the school. TPECI will also perform site work during the soil removal, taking samples to verify to DEC that the contamination has been removed, as well as produce a final report documenting site activities. The budget for this project has approximately $62,000 remaining, sufficient for this change order cost. Travis/Peterson Environmental Consulting, Inc.

(TPECI) to develop and implement a Soil Removal and Vapor Intrusion Work Plan for the Kodiak Island Borough Karluk School in Karluk, Alaska. The Soil Removal Plan will focus on excavating the contaminated soils located along the eastern side of the school. The Vapor Intrusion Work Plan will respond to the Alaska Department of Environmental Conservation request for evaluating the school's indoor air inhalation pathway relative to nearby contaminated soils. The Soil Removal Plan will describe using a mini -excavator to excavate the petroleum - contaminated soils alongside the school as discussed in the Site Characterization Report. Approximately 30 cubic yards of diesel contaminated soil exists at this location. The Work Plan will also include contaminated soil treatment and disposal methods. The Vapor Intrusion Work Plan will provide methods for assessing air quality for volatile gases in the Karluk School. This may involve inserting monitoring probes along the school exterior wall as well as installing passive air monitoring devices in the school's crawlspace. TPECI estimates the cost to complete this work is $33,700 assuming poor weather conditions do not restrict travel or disrupt working conditions. See the enclosed cost breakdown spreadsheet for more detail. A work day in the field is 12 -hours. TPECI assumes air sampling equipment rental, sample analysis, heavy -equipment rental, heavy -equipment operator, and lodging will be provided by the Karluk School and was not included in cost estimates. Travis/Peterson Environmental Consulting, Inc. Page 2 TPECI anticipates completing the field work in July of 2018. Upon receipt of sample results, TPECI will provide a written report within 10 working days. Please feel free to contact our office if you have any questions regarding this proposal. TPECI appreciates your business and looks forward to working with you. Sincerely, Ryan Kmgsbery �1 Staff Scientist CC: Michael Travis, P.E., Travis/Peterson Environmental Consulting, Inc.

The Report was submitted via email on September 19, 2017 by Travis/Peterson Environmental Consulting, Inc. Fieldwork was conducted on August 6 through 8, 2017 and generally consisted of advancing ten soil borings and collection samples for field -screening and laboratory analysis. The objective was to delineate the horizontal and vertical extent of petroleum contamination. Analytical data collected confirmed that petroleum contaminated soil is limited to depths of 5 and 15 feet below ground surface. Diesel range organics (DRO) was identified near all three former UST's. Ethylbenzene in two samples (SB5-5 and duplicate SEX -99), collected by the generator, were up to 22 times the 18 AAC 75.341 Table B1 Over 40 inches Human Health cleanup level and approximately three times above the Migration to Groundwater (MI'G) cleanup level. Both analytes were detected above 18 AAC 75.341 Table B2 Method Two Migration to Groundwater soil cleanup levels. In samples SB5.5, SB99 .Y, and SD6-5, 1-Methylnapthalene and 2-Methy1napthalene remain in the subsurface between 5 to 15 feet bgs at concentrations two to three times the MTG cleanup level. Naphthalene coneersmtions 3 to 21 times the MTG cleanup level were also confirmed in samples SB5-5, SB99 .Y, and SB6-5. Groundwater was not encountered during August 2017 field activities. This report is approved. Petroleum -contaminated soil remains above applicable cleanup levels between 5 and 15 feet below ground surface, and within 30 horizontal feet of the Kaduk School. Volatile compounds were confirmed present in sails at the site; therefore, the indoor air inhalation pathway needs Matt Gandcl Kodiak Island Borough October 11, 2017 to be evnlunted.
