(TPECI) has calculated an estimated cost for completing work at the Chinink School as outlined in the Chiniak School Site Characterization Work Plan. The estimate includes site work, sample analysis, a site characterization report, and coordination with the Alaska Department of Environmental Conservation. As stated in the work plan, TPECI will delineate the horizontal and vertical extent of petroleum -contaminated soils around the former location of the leaking 500 -gallon underground storage lank (UST). Delineation will occur using soil borings advanced with a mobile Minuteman"' drill rig. Additional work involves the collection of soil samples from the contaminated soil stockpile and potential installation of a temporary monitoring well including collection of groundwater samples. The monitoring well will not be installed if groundwater is not encountered in the soil borings. TPECI estimates the cost of this work will be $17,455. This cost assumes that the Kodiak Island Borough will contract directly with Denali Drilling and SGS Laboratories for their services. TPECI anticipates Ilse work outlined in this work plan will occur within a two-day period. See the enclosed cost breakdown spreadsheet for more details. Don't hesitate to contact me or Michael Travis if you have questions.

Chiniak School Site Characterization Work Plan 1322.06, Kodiak Island Borough 1.0 INTRODUCTION Page 3 May 2017 The Kodiak Island Borough, (KIB) contracted Tmvis/Peterson Environmental Consulting, Inc. (TPECI) to develop a site characterization plan to investigate contaminated soils at the Chiniak School (hereinafter: school) located at 42650 Chiniak Highway on Kodiak Island, Alaska. In July 2014, KB and TPECI closed one previously regulated 12,000 -gallon underground storage lank (UST) in-place (Facility ID# 3345), removed one unregulated 500 -gallon UST, and all associated fuel piping. During the removal process, TPECI observed petroleum -contamination in subsurface sails surrounding the 500 -gallon UST indicating it had slowly leaked fuel over an extended period of time. A weathered diesel odor was also noted at two distinct areas along associated fuel piping. Approximately 79 - cubic yards of contaminated soil was excavated around the leaking UST and stockpiled in containment cells located on site. The site was added to the Alaska Department of Environmental Conservation (ADEC) Contaminated Sites Database on October 7, 2015 (File# 2524.38.002). On March 3, 2017, KB received a letter from the ADEC requesting delineation of the horizontal and vertical extent of the contamination discovered at the site during the 500 -gallon UST removal. The letter also requested sampling of the contaminated soil stockpile. The goal of this site characterization work plan is to provide the KIB and ADEC with this information. The plan consists of the following: • Advancing soil borings; • Screening and collecting laboratory soil samples; • Collecting laboratory water samples if groundwater is encountered; 1.1 SITE DESCRIPTION AND BACKGROUND LL1 Location • Standard operating procedures; • Coordination with the ADEC; and • Documenting and reporting requirements. The property is located near Chiniak, Alaska, which lies 12.3 -miles southeast of the City of Kodiak along the southern shore of Chiniak Bay. Figure 1 in Appendix A is a vicinity map showing the site location within the region. Figure 2 in Appendix A is a site map showing the school, neighboring structures, and project boundaries. The latitude and longitude coordinates for the site are: 57.61349° N, 152.2347° W. 1.1.1 Geology and Hydrology The terrain surrounding the project site is a gradual slope to the northwest with tall Sitka spruce trees surrounding the school. An unpaved access road bisects the property and runs between the school and a generator/water treatment (GenSet) building to the teacher's residence behind the school. There is a small stream that runs west -east between the soil stockpile and the school (Figure 2). Drinking water for the school and the teacher's residence originate from a well located upgradient and 1,900 -feel southwest of the property (Figure 2). Soil types at the site are primarily silt, ash, and poorly - graded sandy and silty gravels. Permafrost is not present at the site. Groundwater elevation is unknown. 1.1.3 Project History In January 2014, the KB contracted TPECI to create a UST Decommission !Pork Plan that described the work and methodologies for decommissioning both the 12,000 -gallon and 500 -gallon USTs. This work plan was submitted to the ADEC on January 10, 2014. The following paragraphs summarize the activities that occurred during the UST decommission process. Travis/Peterson Environmental Consulting, Inc. Chiniak School Site Characterization Work Plan Page 2 1322-06, Kodiak Island Borough May 2017 On July 28, 2014 Nortech Environmental decommissioned the 12,000 -gallon UST in-place. Three test pits were dug around the UST in areas where contamination was most likely to be present and was in accordance with test pit excavation procedures as outlined in the ADEC UST Procedure' Manual (August 2014). TPECI directed the excavation and screened soils in each test pit using standard heated headspace field screening protocol as outlined in the ADEC Field Sampling Guidance (March 2016). Screening samples did not detect any contamination. Four laboratory confirmation samples were then collected and analyzed for diesel range organics (DRO), residual range organics (RRO), gasoline range organics (GRO), benzene, toluene, ethylbenzene, total xylenes (BTE)), and polycyclic aromatic hydrocarbons (PAH). All sample results were below ADEC migration to groundwater cleanup levels. On the following day, TPECI observed the excavation and removal of the 500 -gallon UST. During the removal process, TPECI did not observe secondary containment, overfill protection or cathodic protection. Contaminated soils were first observed at about two feet below ground surface (bgs) at the lop of the UST. As the tank was lifted, fuel was observed pooling in soils immediately beneath the tank. Excavation of contaminated soil continued under TPECI guidance until obstructing utilities surrounding the excavation and proximity to the school building (<10 -feet) halted soil excavation. TPECI then collected four heated headspace field screening samples from the excavation sidewalls and one screening sample from the excavation base. Sidewall samples were collected at approximately six feet bgs where contamination appeared to be the most prevalent. All samples, except one, collected from the sidewalls contained elevated levels of volatile organic compounds (VOCs). The screening sample collected from the base contained VOCs but visual and olfactory inspection did not indicate that soils at the base were contaminated. TPECI then collected four laboratory confirmation samples from the excavation base at approximately 10.5 -feet bgs. No samples exceeded ADEC migration to groundwater cleanup levels for DRO, RRO, GRO, BTEX, or PAH. The lab results confirmed that the contaminated soil located immediately underneath the leaking 500 -gallon UST had been successfully removed. The results also confirmed that contaminated had not reached groundwater since groundwater was not observed during excavation. However, heated headspace screening samples collected from the excavation sidewalls indicated that contaminated soils remain in the perimeter of the tank footprint and likely extend into downgradient soils. This conclusion is the primary reason that this site characterization work plan is required for this site. At this time, TPECI also collected heated headspace screening samples and laboratory samples from two areas of concern along the associated fuel pipes connecting the USTs with the school, GenSet building, and teacher's residence. The first area of concern involved stained soils observed under pipe joints closest to the GenSct building. A laboratory sample was collected at this area and analyzed for DRO, RRO, GRO, BTEX, and PAH. Sample results showed concentrations above the ADEC migration to groundwater cleanup level for DRO (10,400 mglKg). No other analyte exceeded ADEC cleanup levels. TPECI determined that soils at this location were contaminated during a pipe rupture caused during unrelated digging activities described in subsection 1. 1.4 of this document. The second area of concern involved stained soils observed under fuel pipe joints around the 500 -gallon UST. A laboratory sample collected from this area contained high concentrations of DRO (2,930 mg/Kg). This may be where the leak from the UST originated, as no hole was found in the UST when it was removed and inspected. On September 8, 2014, TPECI submitted the Chiniak School UST Decommissioning Summmy Report to the ADEC. For more detail, please consult that report. 1.1.4 Previous Enviranrrrenralll'ork Previous unrelated environmental work at the site includes the removal of contaminated soil created during a 500 -gallon diesel spill at the teacher's residence on November 17, 2009 (Spill# 09249932101). Soils were excavated and treated in a landform created on school property in 2010. The case was closed with no further action on January 29, 2013. Travis/Peterson Environmental Consulting, Inc. Chinink School Site Characterization Work Plan Page 3 1322-06, Kodiak Island Borough May 2017 In September 2011, Satori Group, Inc. discovered contaminated soil around a 500 -gallon UST located on the south side of the GenSet building (File# 2524.26.001). Approximately 55 cubic yards of contaminated soil was removed and approved by the ADEC in December 2012 to be treated on site in the existing landfarn. During the UST removal process an adjoining fuel pipe was accidently ruptured. During the pipe rupture an unknown volume of fuel was spilled. Cleanup of the resulting contaminated soils would involve the removal of the GenSet building to allow for access. This is believed to be the only other remaining soil contamination at the property and is being managed with institutional controls. All landfarmt maintenance was halted in the fall of 2013. No evidence of the landform is visible today. L1.5 Surrounding Uses The school site is surrounded by residential property. There are no active ADEC-listed contaminated sites within the vicinity. In August 2015, a wildfire burned approximately 5,000 -acres or forest to the south of the property. The wildfire was put out within 600 -feet of the school. 2.0 SAMPLING AND ANALYSIS PLAN The KIB requested TPECI to complete a site characterization work plan that provides methodology for determining the extent of soil contamination at this site. This work plan follows the recommended elements and general guidelines provided in the ADEC Site Characterisation !York Plan and Reporting Guidance for Investigation of Contaminated Sites (March 2017). TPECI personnel meet the ADEC definition of "Qualified Environmental Professional" in accordance with 18 Alaska Administrative Code (AAC) 75.333. TPECI personnel assigned to this project have not been determined at this time and TPECI can provide personnel resumes as requested. While on site, TPECI personnel will be aided by KIB personnel and additional contractors as necessary. 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 former location of the 500 -gallon UST by the school. TPECI will use a mobile gas -powered Minutemanvt drill rig to advance small -diameter soil borings at five locations within the project area. A split -spoon sampler will be used to collect heated headspace screening samples and laboratory samples. Samples will be systematically collected from the soil borings at depth. TPECI will also collect water samples should groundwater be encountered. Water samples will be collected by installing a temporary water well and peristaltic pump. Additionally, TPECI will collect heated headspace screening samples and confirmation samples from the contaminated soil stockpile. TPECI will ensure drat all sampling will be conducted in accordance with this work plan. Sample results will determine Trow remedial action and soil treatment or disposal is initiated. 2.2 PROJECT FOOTPRINT The project site encompasses approximately two acres and includes the stockpile footprint. The actual area of concern containing petroleum -contaminated soil is around the former location of the 500 -gallon UST. Four soil borings will be focused in this area. Buried utilities will limit where soil borings can be advanced. Known utilities at this location include the school's communications, electrical, water, sewer, and heat recovery lines. See school as -built drawings in Appendix B. Travis/Peterson Environmental Consulting, Inc. Chiniak School Site Characterization Work Plan 1322-06, Kodiak Island Borough Page 4 May 2017 At the ADEC's request, TPECI will advance a single soil boring behind the school. The purpose of this boring is to confirm that heating oil from the leaking UST did not seep underneath the school foundation. 2.3 CONTAMINANTS OF CONCERN Contaminations of concern (COC) were determined using Table 2A of the ADEC Underground Storage Tank Procedures Manua! (August 2014) for "Diesel #1" (heating oil). TPECI personnel will test soil for DRO, GRO, and BTEX with 10% of samples tested for PAH. COC cleanup levels for this region are Method Two migration to groundwater for the Over 40 -Inch Zone as listed in Table B2 of 18 AAC 75.341. Table 1 below shows the cleanup levels for each analyte.

Chiniak School Site Characterization Work Plan Page 5 1322-06, Kodiak Island Borough May 2017 2.4 SOIL BORING SCREENING AND SAMPLING To identify the horizontal and vertical extent of contamination, TPECI proposes drilling a minimum of five soil borings at the site. Figure 3 in Appendix A shows the approximate locations that TPECI intends to drill soil borings. Four of the five proposed soil borings are clustered around the former location of the leaking 500 -gallon UST. The exact location of these borings will be determined by the location of buried utilities in this area. One soil boring will be drilled behind the school to determine whether or not fuel has seeped under the school foundation. All soil borings will be drilled to a depth of 15-R or to refusal, whichever comes first. TPECI believes a 15 - ft deep soil boring is adequate for vertical characterization because confirmation samples collected directly underneath the leaking UST, at 10.5 -ft bgs, contained DRO concentrations less than the ADEC migration to groundwater cleanup level (45.3 mg/Kg). Thus, contamination is not likely present in surrounding soils beyond a depth of 15-f). A heated headspace screening sample will be collected from a split spoon sampler at five foot intervals. TPECI will screen soils using a MiniRAET^t Systems 3000 photo -ionization detector (PID). The PID will detect VOCs in parts per million (ppm). TPECI will then collect a laboratory sample from soils with the highest concentration of VOC as determined by the PID. TPECI will collect a second analytical sample from soils at the bottom of the soil boring or at the groundwater interface if groundwater is encountered. Additional laboratory samples will be collected from soils ifvisuallolfaclory observations of contamination are noted, if PID readings are inconclusive due to high moisture content, or if the contamination is found within gravel or cobbled rock. If contaminated soil is found in any soil boring, TPECI may advance additional soil borings to identify the horizontal extent of the contamination. A minimum of one laboratory sample will be collected per soil boring even if all heated headspace screening samples indicate an absence of contaminated soil. A duplicate sample will be collected from the area containing the highest VOC readings as determined by the heated headspace field screening samples. Laboratory samples will be analyzed for the COC as described in Section 2.3 of this document. Both screening samples and laboratory samples will be collected using methods and procedures outlined in the ADEC Field Sampling Guidance (March 2016).

These Travis/Peterson Environmental Consulting, Inc. Chinink School Site Characterization Work Plan Page 6 1322-06, Kodiak Island Borough May 2017 procedures are outlined in detail in Section 3 of this document. The number of recommended field screening samples and laboratory samples will be determined by the parameters outlined in Table 3 below.

Contaminated soil boring cuttings will be added to the contaminated soil stockpile. See Section 4.0 of this document for more details on investigation derived waste. 2.5 GROUNDWATER SAMPLE COLLECTION Groundwater is not expected to be encountered during the site characterization process. However, should groundwater be encountered, TPECI will collect a water sample to test for petroleum -hydrocarbon contamination. TPECI will utilize a drive -point temporary groundwater monitoring well in order to collect a water sample. The well will be installed within the excavated soil boring following the collection of laboratory soil samples. The temporary monitoring well will be comprised of 1/+ -inch casing affixed to a commercially manufactured machine -perforated drive -point. The perforated section of the drive -point will be approximately 24 -inches in length and will placed at the static groundwater depth as determined by the groundwater/soil interface. The casing will extend from the base to a few feet about ground surface. The annulus between the well casing and boring sidewalls will be partially backfilled with inert clean material (sand). Backfill material will be used for half the well length. This is to ensure that the well can be removed without the use of heavy -equipment. After backfilling following monitoring well installation, TPECI personnel will wait to allow groundwater stabilization to provide a representative sample of groundwater. According to the ADEC Monitoring Well Guidance Manual (September 2013), this period of time could be up to 24 -hours for an excavation -installed well. Given that this is a soil boring -installed well with minimal localized soil disturbance, TPECI will wait at least 12 -hours prior to purging/sampling groundwater. Following a 12 -hour period, TPECI will use a water -wheel meter for depth -to -groundwater measurement and to confine that groundwater levels within each well are in stasis. If the groundwater level is still Fluctuating, then TPECI will wait until it is in stasis. The water -wheel meter will be used to measure the distance from the bottom of the well to the top of the casing. The difference between these two points will be calculated to determine the number of feet of groundwater in the well -point casing and convert this amount to gallons. A peristaltic pump will be used to purge at least two times the calculated well volume. All purged water will be pumped into a five -gallon bucket during this process. Upon completion of the purging process, TPECI will replace the peristaltic pump tubing with new tubing. Groundwater will then be collected and samples for the COC. Groundwater samples will be collected, handles, and stored in accordance with the ADEC Field Sampling Guidance (March 2016). Details pertaining to the water sample collection process are provided in Section 3.0 of this document. The number of recommended laboratory water samples will be determined by the parameters outlined in Table 4 below. Travis/Peterson Environmental Consulting, Inc.

Depth Lab Samples Lob Sample Duplicates Monitoring Groundwater/Soil 1 sample I duplicate Well Interface Page 7 May 2017 After collecting water samples, TPECI will remove the well so as to not impede continued site access or pose a risk to human health or the environment. The soil boring will then be backfilled with sand and annular sealed with bentonite pellets at the surface to two -feet bgs. The disposal of used pump tubing and purge water is discussed in Section 4.0 of this document. 2.6 STOCKPILE SCREENING AND SAMPLING As discussed in Section 1.0 of this document, the secondary objective of this site characterization workplan involves sampling the existing contaminated soil stockpile located on site. The stockpile was last sampled by TPECI on July 31, 2014. The total volume of stockpiled soil is 79 -cubic yards. Per Table 2A of the ADEC Field Sampling Guidance (May 2016), three laboratory samples and eight heated headspace screening samples must be collected to adequately characterize a stockpile of this size. Samples will be collected from all sides of Ilse stockpile for an accurate representation. TPECI will then collect three laboratory samples from soils with the three highest VOC concentrations as determined by heated headspace screening. The number of recommended field screening samples and laboratory samples will be determined by the parameters outlined in Table 5 below. Table 5 Sol[ Screening and Laboratory Sampling Parameters for the Stockpile Area Appros Volume Screening Samples Lab Samples I Lab Sample Duplicates 3 samples collected from Stockpile 79 -cubic yards I per 10 cubic yards soils with top 3 1 duplicate per 10 samples highest VOC concenimtions Duplicate samples will be collected from areas containing the highest VOC readings. Laboratory samples will be analyzed for the COC as described in Section 2.3 of this document. Following the collection of samples, the stockpile's geo-membrane cover will be re -installed and secured with orange fencing and signage. 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 (told -times and sample temperatures shall be maintained. The laboratory Quality Assurance Project Plan is filed at the laboratory and at TPECI. Thus, the SOP contained herein refers to generic field sampling and sample preparation. 3.1 FIELD SOP The hand-held PID will be calibrated 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 Travis/Peterson Environmental Consulting, Inc. Chiniak School Site Characterization Work Plan Page 8 1322-06, Kodiak Island Borough May 2017 before departure to the field because of Federal Aviation Administration regulations associated with the shipping and handling of compressed gas. Heated headspace screening samples will be collected using a PID, to screen potentially contaminated soils. The PID will be used to identify VOC concentrations using the heated headspace method in a scalable plastic bag such as a quart -sized Ziplock& Rocks will be removed from samples as necessary using a sieve. Sealable plastic quart -sized bags will be filled half full with soil. The plastic bag will then be shaken for 15 -seconds and allowed to warm up for at least 10 -minutes (but not more than one hour) to between 500 and 70• 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. Field personnel shall keep detailed notes that include: • Project name/Site ID/Client/Page Number; • Date; • Weather, site conditions, and other salient observations; • Full name of onsite personnel, affiliations and project title e.g., team leader (including all visitors); • Daily objectives; • Time and location of activities; • Field observations and comments; • Deviations from the CSP site-specific approved work plan; • Photographic log (photographic name, roll or frame number, description of photograph, date, and time); • Site sketches with reference to north direction, sample and field screening locations and depths, and on-site groundwater flow direction; • Survey and location (latitude and longitude coordinates when possible); • All field measurements (e.g. leak check results, geachemical parameters, field screening results); • Daily equipment calibrations and maintenance; • Sample record (sample identification, date, time, media, number of samples, and location); • Cleanup or remediation activities (system performance, system calibration or maintenance record, excavation activities and volume of material removed); and • Waste tracking (when, how much, destination). Site drawings shall be included within the field notes as part of the field investigations. Site drawings should include a north arrow, and, if applicable, at least one permanent identifying feature (such as a building). All samples collected (screening and analytical) should be noted on a figure. All laboratory sampling locations shall be documented within the field notes. If applicable, the sampling location cross-sectional view may be drawn. Any unusual characteristics of the sampling location and any problems encountered during sample collection shall also be recorded for each sample location. GPS coordinates of each soil boring shall be documented within the field notes. 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. Filed 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. Travis/Peterson Environmental Consulting, Inc. Chiniak School Site Characterization Work Plan Page 9 1322.06, Kodiak Island Borough May 2017 3.1.1 Field Sample Preparation SOP All samples, soil and water, 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 Environmental Protection Agency (EPA) Method 8021B, and DRO by method AKIO2. One sample for every 10 laboratory samples will also be analyzed for PAH using EPA Method 8270D to comply with ADEC's requirement of 10% sampling of PAH for diesel contamination (ADEC March 2016 Field Sampling Guidance, dppendlr F). Table 6 shows the analytical methods and sample requirements required for each test.

Soil sample containers will be filled to a mass ranging from 25 to 50 -grams of soil (approximately 1/314 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 25-m1 of preservative be required for a given sample, documentation of total preservative volume will be recorded in the field notes. Travis/Peterson Environmental Consulting, Inc. Chiniak School Site Characterization Work Plan Page 10 1322-06, Kodiak Island Borough May 2017 3.1.2 Field Decontamination Procedures Field personnel will use clean disposable nitrile 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 Alconox® detergent or similar cleaning solution and will be scrubbed, rinsed, and dried. The small volume of wash and rinse water will be collected in a bucket or drum and stored on site. If necessary, TPECI will use absorbent pads to remove sheen from the rinse water. See Section 4 of this document for investigation derived waste. 3.1.3 Field and LaboratotiCalibration Methods All field and laboratory procedures requiring instrument calibration will be conducted according to the applicable EPA methods, ADEC methods, and standard operating procedures. The manufacturer calibrates the PID annually. As previously discussed, the PID will also be calibrated with fresh air and a 100 -ppm isobutylene calibration standard before it is used. The EPA checks the calibrations traceable quality control standards for the laboratory. 3.1.4 Routine and Periodic Quality Control Activities SGS North America Inc. (SGS), an ADEC-approved laboratory, will he used for all laboratory sample analysis. The following subsections describe the methods used for determining the quality of laboratory results. 3.1.5 Field Quality Control Samples Field personnel will take two types of field quality control samples: 1) sample duplicates, and 2) blanks. The objective and frequency of these samples are discussed below. TPECI will not collect field blanks or equipment blanks for this project. TPECI will rely on field duplicates and trip blanks for quality control and determination of artificially -introduced contamination. 3.1.5.1 Field Duplicates Field duplicates are samples collected simultaneously from the same sampling locutions. Field personnel will use identical sampling methods to retrieve one duplicate for every 10 samples. TPECI will follow the same QA/QC methods for collecting, packaging, recording, and shipping the duplicate samples as all other samples. 3.1.5.2 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. This 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. 3.1.5.3 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. 3.1.5.4 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 field decontamination procedures as described in subsection 3.1.2 of this document. Travis/Peterson Environmental Consulting, Inc. Chiniak School Site Characterization Work Plan Page 11 1322-06, Kodiak Island Borough May 2017 3.2 LABORATORY SOP SGS 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, 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. 31.1 Data Reduction, Validation and Reporting Data reduction is conducted by the analyst. All calculations are made as specified by the particular analytical method being analyzed. Units are reported as mg/Kg, pg/Kg, 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. Upon receipt of the analytical laboratory report, TPECI will review the data and complete the ADEC Laboratory Data Review Checklist form. 4.0 INVESTIGATION DERIVED WASTE Decontamination waste, disposable personal protective equipment, disposable sampling equipment, used peristaltic pump tubing and all other investigative derived solid or liquid waste shall be placed in labeled 5 -gallon buckets. After project completion, TPECI will take the buckets to the Kodiak landfill for disposal. The Kodiak Island Borough landfill is a Class 1 landfill located at 1203 Monashka Bay Road. All contaminated soil boring cuttings will be stored in a 55 -gallon drum. TPECI does not anticipate generating more than four cubic feet (30 -gallons) of soil boring cuttings. After all soil borings have been drilled, the contents of the drum will be added to the contaminated soil stockpile. Tltis will only occur if soil cuttings are less than or equal in concentration to that of the stockpile as determined by healed headspacescreening. Travis/Peterson Environmental Consulting, Inc. Chiniak School Site Characterization Work Plan 1322.06, Kodiak Island Borough 5.0 PROJECT SCHEDULE Page 12 May 2017 The KIB intends to commence the work outlined in this site characterization work plan in the summer of 2017. The school will not be occupied with students at this time. TPECI does not anticipate the field work outlined in this plan will take longer than two days. Development of a written report on site activities shall occur following the receipt of laboratory data results. Currently, laboratory tum -around times range from two to six weeks. The development of a complete report is estimated to be completed within two weeks following receipt of laboratory data results. TPECI will notify the ADEC project manager by phone and/or email at least ten calendar days prior to beginning site work. 6.0 DELIVERABLES The data deliverables for this project shall include summarizing field activities, results, and conclusions. information: • Site characterization overview; at the completion of the project, a written report The report shall specifically address the following • Laboratory results summary for sail baring samples, stockpile samples, and groundwater samples (if applicable); • Laboratory results; • Data Validation and Completion of ADEC Laborarorr Data Revietr Checklist; • Field observations; • Investigation findings; and • Recommendations for future site work if necessary. 7.0 CONCLUSIONS It will be the goal of TPECI to provide die KIB and the ADEC with a comprehensive understanding of the extent of contamination present at this site. Soil samples collected from multiple soil borings will provide information into the vertical and horizontal extent of the contamination. If collected, groundwater samples will determine whether groundwater has been impacted at this location. TPECI will use this information to generate a site characterization report that summarizes field activities, sample results and recommends corrective actions for site remediation. In the case of unforeseen circumstances, TPECI will coordinate with the ADEC during field activities. The ADEC can provide TPECI with additional guidance an screening and sampling methods.

(TPECI) to develop a Landfaim Work Plan for contaminated soil at Chiniak School. In 2014 KIB closed two underground fuel tanks at the school. During that work approximately 80 cubic yards of contaminated soil was removed and stockpiled near the school. In June 2017 KIB entered into a Professional Services Agreement with TPECI to perform soil sampling of the stockpile mandated by the Alaska Department of Environmental Conservation (DEC). Now that samples have been taken determining the current level of contamination, DEC is requiring a written work plan to move the soil to a landfarm location across the entrance road to the school. TPECI will also perform site work to monitor the landfarm construction and produce a final report documenting site activities. The budget for this project has approximately $43,000 remaining, sufficient for this change order cost. J Travis/Peterson Environmental Consulting, Inc.

(TPECI) to develop and implement a Chiniak Landfarm Work Plan for the Kodiak Island Borough (KIB) Chiniak School in Chiniak, Alaska. On November 16, 2017, the Alaska Department of Environmental Conservation requested the KIB develop a work plan for treating and disposing of approximately 79 cubic yards of contaminated soil currently stockpiled on site. The work plan would satisfy this request. The Landfarm Work Plan will detail landfartn construction and maintenance, as well as provide a sampling schedule to monitor contamination. TPECI believes the landfarm could be constructed in the same area along the Chiniak School access road, which has been used for landfarming in the past. TPECI estimates the cost to complete this work is $16,500 assuming poor weather conditions do not restrict travel or disrupt working conditions. This estimate includes two trips to Chiniak — one for landfarm construction and a second for an annual landfarm assessment and soil sample collection. A work day in the field is 12 -hours. TPECI assumes sample analysis, heavy -equipment rental, and heavy -equipment operator will be provided by the KB and was not included in cost estimates.

The report summarizes work completed at the site in 2017. A total of eight soil samples were collected from five soil borings, which were drilled in the former underground 1.101' excavation, as well as on the side of die school oppwite the former pit to check for contaminadon migration. Groundwater %vas not encountered in any of the sail borings. One soil sample collected from soil boring 2 (SB -2) at a depth of 5 feet (&) below ground surface (bgs) contained diesel range organics (DRO) up to 409 mi ligeims per kdogmm (mg/kg), which is above the ADEC Method Two migntion to groundwater (NI TG) cleanup level of 230 mg/kg. A sod sample collected nr 15 ft bgs from S13-2 did not contain DRO concentrations above the ADEC Method Two M TG cleanup level, which indicates the vertical extent of eontaminacion has been defined. Additionn8y. SB -2 is located direcdy adjacent to the building foundation and removing soil in that location may compromise building integrity. Characterization of the soil stockpile included the collection of four analytical soil samples. These soil samples contained diesel range organics (DRO) up to 618 mg/kg. Based off this review, ADEC will not require further evaluation of the underground HOT nt this time. I•lowet'cr soil in the stockpile contains DAO above the ADEC Method Two M TG.cleanup level. Please submit a work plan regarding plans for fiuther treating, testing, or disposal of the stockpile to the ADEC by January 1, 3017.
