Landfill Soil Remediation Kodiak, AK February 23, 2026 TO ALL PLAN HOLDERS OF RECORD: This addendum forms part of and modifies the contract documents as noted below. Bidders must acknowledge receipt of this addendum in the space provided on the Acknowledgement of Addenda form. Failure to do so may submit Bidder to disqualification. This addendum consists of 1 page and attachments. Bidder's Questions: Question 1: Square footage of the space will be determined by how much material is left over after sifting, but not higher than 30" total and that includes 6" of sand? Response 1: Correct. The final depth and overall square footage will be determined by the amount of material remaining after the 2" screening activity. The final depth cannot exceed 30" overall, with a 6" minimum of sand. Question 2: We can use black liner for the bottom as long as its 20Mil? Response 2: Yes, the bottom of the containment must be 20 mils thick. We do not specify a color. Question 3: Clear 6 Mil for the top? Response 3: Yes, we prefer a clear 6 -mil poly liner for the cover. You will also need sand, soil, or similar material placed on this cover to keep it secure. Question 4: We can pull berm material from the pile of Cover Rock Storage that is shown on the print next to the proposed site? Response 4: Yes, you can use the 2" screened rock or similar cover rock next to the landfarm location to create the berm. Once this material passes the PID, it will all become cover for the landfill. Question 5: Testing will be in 10x10 grids twice a year following the schedule in the addendum? Response 5: Correct. The testing is biannual, and it must follow the specifications outlined by ADEC in the documents. KODIAK ISLAND BOROUGH ADDENDUM NO. 2 Landfill Soil Remediation PAGE 1 Question 6: KIB indicated that field screening (with PID) would be the determinative factor for landfarm soils characterization, not soil sampling. Please confirm that bidders should not assume any laboratory sampling expense for this project Response 6: Yes, PID screening will be sufficient for characterization of soils to be landfarmed Question 7: During the site walk at the landfill location, bidders identified that soils are several hundred feet away from the proposed landfarm location, and containers were in poor condition. Typically, the ADEC requires the onsite presence of a QEP during all "soil moving operations" when handling contaminated media. Please confirm the duties that trigger the onsite involvement of a QEP (e.g., relocate on of soils from their current location, sieving and segregating rock from fines, verification of landfarm cell construction, placement of fines into the landfarm cell, field - screening with PID twice yearly) to ensure that all bidders assume the same level of onsite involvement of this key position. Response 7: Yes, a QEP will be helpful to have onsite during the movement of soils to conduct PID screenings to ensure we are only treating soils that exceed 20 ppm on the PID. Question 8: Can you provide photos of the soil inside the supersacks? Response 8: Yes, we took some photos of the soil in one of the open bags at the site visit. Those photos will be provided as a OneDrive link site photos included in the email with this addendum #2 to all registered bidders and posted online with the Invitation to Bid. Question 9: During the pre-bid conference, it was stated that the Addendum [Exhibit B] takes precedence over the initial work plan [Exhibit A]. The Addendum [Exhibit B] does not explicitly state that tilling is required, while the initial work plan does. Is it the intent to have the contractor do the tilling? If so, what Item No. on the Bid Schedule (page 15 of the ITB) will that scope be reflected? Response 9: For clarification, the referenced addendum is Exhibit B, titled Addendum to Landfarm Work Plan for Contaminated Soil at Kodiak Island Borough Landfill, Kodiak, Alaska, Identification Number 18249925501. Exhibit B takes precedence over the initial Work Plan (Exhibit A). The contractor is not responsible for tilling. KODIAK ISLAND BOROUGH Landfill Soil Remediation ADDENDUM NO. 2 PAGE 2 Question 10: The Projected Project Timeline in the Landfarm Work Plan Addendum lists "Land Preparation/Procure Supplies" under KIB responsibility. Does that mean that the KIB will be responsible for the procurement of the liner and fill for the Iandfarm berm and sacrificial sand above the Iandfarm liner? Response 10: No, KIB is the responsible party per the Alaska Department of Environmental Conservation (ADEC). The intent is to hire a contractor who will be responsible for providing all labor, materials, tools, equipment, transportation, supervision, and facilities necessary to: • Screen the material and remove any material 2 inches or larger in accordance with (IAW) Exhibit B; • Construct the Iandfarm and place contaminated materials in the Iandfarm IAW Exhibit B; • Complete PID screenings in accordance with the Site Characterization section of Exhibit B; and • Complete all required ADEC reporting in accordance with the requirements outlined in Exhibits A and B. Question 11: Is the decommissioning of the Iandfarm cell also included in this scope? Response 11: The selected contractor will be responsible for fulfilling all Alaska Department of Environmental Conservation (ADEC)-specific decommissioning requirements, including submission of satisfactory PID screening results and obtaining any necessary approval determinations from Alaska Department of Environmental Conservation in accordance with the reporting requirements outlined in Exhibits A and B. However, KIB will be responsible for demolition of the Iandfarm and the spreading of soils after they have been cleared by ADEC.

Marked information confidential; ii. For any information marked confidential, identified the authority that makes that specific information confidential; and iii. Committed, in writing, to explain in detail, including with affidavits and briefs, why each authority applies in any court or administrative proceeding in which any nondisclosure is challenged. Landfill Soil Remediation Invitation to Bid Page 9 of 33 e. If the bidder did not undertake each protective measure, the Borough will not consider any information in a Record confidential: the Borough will disclose the entire Record without any redaction in response to an APRA or other request or, if it chooses, in the absence of a request and the Borough will disclose the entire Record without notifying the bidder. f. If the bidder undertook each protective measure, the Borough will withhold the information marked confidential to the following extent: i. The Borough agrees that the Law protects the information; and ii. If the nondisclosure is challenged, the bidder fulfills its commitment to explain, including with affidavits and briefs, how each authority applies to the information marked confidential. g. The Borough will only notify a bidder of a request for the Record and of a planned release if the bidder undertook each protective measure, but the Borough disagrees that the marked information is protected. If there is such a disagreement, then before releasing the Record, the Borough will, to the extent permitted by Law and practicable, notify the bidder that it will disclose the information unless the bidder convinces the Borough not to or obtains an order prohibiting disclosure. 16.0 COMPLIANCE In the performance of a contract that results from this ITB, the contractor must comply with all applicable federal, state, borough and other local regulations, codes, and laws, and be responsible for all required insurance, licenses, permits, and bonds.

This Plan has been prepared in accordance with 18 AAC 78.250(e)(3) and 18 AAC 78.250(e)(8). Landfarming is a cost effective and efficient method for remediating PCS in locations where thermal treatment and other soil remediation methods are not feasible. An ADEC Landfarming Checklist is provided in Appendix A. 2.0 SITE DESCRIPTION AND BACKGROUND On August 10, 2018 Kodiak Island Borough (KIB) staff at the Landfill observed what was believed to be a small diesel spill during the filling of an underground storage tank (UST) providing heating fuel to the Baler Building. The spill was reported to the Spill Prevention and Response division of the ADEC and assigned file identification number 18249925501. The spill was believed to be the result of a release from a breach in one of the ventilation pipes during filling of the UST. The tank was confirmed to be non-regulated, and ADEC authorized KIB to proceed with tank removal. KIB contracted with Environmental Contracting Solutions (ECS) to provide a Qualified Environmental Professional (QEP) for oversight during the tank removal. Between September 10, 2018 and September 12, 2018, the tank and approximately 71 cubic yards of contaminated soil was excavated and removed. The details of the excavation activities are included in the Decommissioning Report provided by ECS and submitted to ADEC in October 2018. The contaminated soil is currently stored in 71 lined supersacks directly adjacent to the UST location (Appendix B). During the decommissioning process ECS screened each supersack using a handheld photo - ionization detector (PID). The PID results are detailed in Table 1 below.

The samples were analyzed by SGS North America in Anchorage for diesel range organics (DRO), residual range organics (RRO), and BTEX (benzene, toluene, ethylbenzene, and xylenes) compounds. Analytical results are summarized in Table 2 along with the ADEC Over -40 -Inch Zone, Migration to Groundwater (MTG) cleanup levels shown below each analyte (18 AAC 75.341). Sample results above the MTG cleanup level are bolded. Samples collected from the supersacks contain elevated levels of DRO ranging from 1,510 mg/Kg to 4,330 mg/Kg. The samples also contain elevated levels of Ethylbenzene and Total Xylenes. Sample results were significantly lower than the ADEC Maximum Allowable Concentration (MAC) cleanup levels.

The entire land parcel has a total area of 97.34 acres (Appendix B) and contains several active landfill cells, Baler Building, Leachate Treatment Plant, and related infrastructure. To the north lies Monashka Bay, a residential area is to the northeast, with the remaining surroundings undeveloped. The proposed landfarming site is at Lat 57.808401, Long -152.409840, a gravel area with a rock face on the south side. Bedrock is expected to be up to 20 feet below ground surface (bgs). It is unknown if groundwater exists at the site. The closest surface water is Monashka Bay, approximately 2,800 feet from the proposed landfarm site. Residences to the northeast are served by drinking water wells but the closest residence is approximately 3,500 feet from the proposed site. 4.0 BACKGROUND SOIL SAMPLING Prior to the construction of the landfarm, KIB will contract with a Qualified Environmental Professional (QEP) to collect surface soil samples from the location of the proposed landfarm for laboratory analysis. The purpose of the soil samples will be to establish background soil concentrations at the landfarm site. The proposed landfarm is designed without the use of a liner to prevent saturation of the soils and promote volatilization of the petroleum contaminants. This design has been used previously for landfarming PCS generated from UST decommissioning projects at schools located at Chiniak, AK (ADEC File 2524.38.002) and Karluk, AK (ADEC File 2564.26.001) that were approved by ADEC. The ADEC Technical Memorandum states that additional site controls, such as a liner, are required should soils contain contamination above the ADEC MAC cleanup levels (18 AAC 75.341). As discussed in Section 2.0 (Site Description and Background), the concentration of contaminants in the stockpiled soil are significantly below MAC cleanup levels. Since the proposed landfarming operation will be conducted without an impermeable liner, the collection of baseline data is necessary to document the initial conditions at the site. A minimum of four soil samples will be collected from the proposed footprint of the landfarming operation. Soil samples will be collected Kodiak Island Borough Page 4 Kodiak Island Borough Landfill Landfarm Work Plan November 2019 at a depth of six inches bgs. The soil samples will be analyzed for the petroleum hydrocarbons detected (DRO, RRO, GRO, and BTEX). The laboratory analytical methods for the background, baseline, interim, and final confirmation soil sampling are summarized in Table 3. Soil samples will be gathered using surface soil collection methods outlined in the ADEC Field Sampling Guidance (August 2017). ADEC Standard Operating Procedures outlined in the Guidance document will be used for collection, handling, quality assurance/quality control, and data reporting. Soil samples will be analyzed by SGS North America in Anchorage, AK.

The proposed landfarming operation will be conducted at the southwest corner of the landfill. The site is compacted gravel and has a rock wall on one side. The site will be graded to allow soils to drain towards a single corner, thereby preventing the development of saturated conditions within all soils that could prolong the treatment process. Berms will be constructed around the entire perimeter of the landfarm to prevent the landfarmed soil from being transported outside of the landfarm. As mentioned previously, no liner will be used for the proposed landfarming operation. Similarly, no internal piping, sump, or other water collection system is proposed within the landfarm. Any precipitation falling onto the landfarm soils will be removed via evaporation or percolation into the soil. Upon receiving ADEC approval per 18 AAC 78.274(b), the supersacks will be moved to the landfarm site and placed onto the constructed landfarm at a maximum depth of 12 inches over an approximately 45 - foot by 45 -foot area (2,025 square feet). The soil will be spread to a thickness of approximately 10-12 inches to allow for greater exposure to oxygen, resulting in a higher rate of volatilization and biodegradation of hydrocarbons and a more rapid treatment process. After the spreading of soil and collection of pretreatment (baseline) soil samples (Section 6.0), an inorganic nitrogen -based fertilizer will be rototilled into the contaminated soil to promote biological breakdown of petroleum hydrocarbons. The fertilizer should be water-soluble containing inorganic nitrogen with an approximate N -P -K (nitrogen -phosphorus -potassium) ratio of 10:1:1. The ADEC will be notified if additional fertilizer applications are justified. Kodiak Island Borough Page 5 Kodiak Island Borough Landfill Landfarm Work Plan November 2019 The area for the proposed landfarm site is within the Landfill area, which is surrounded by a permanent chain link fence. The fence is kept locked during off hours and only KIB personnel have keys. During open hours Landfill staff will be present to prevent disruption of the landfarm site or any potential risk of exposure to the public. 6.0 BASELINE CONTAMINATED SOIL SAMPLING The QEP will collect a minimum of four representative soil samples from the contaminated soil after it is first spread within the landfarm to evaluate the baseline hydrocarbon and BTEX concentrations. These soil samples will be analyzed for the same analytes discussed in Section 4.0 (Background Soil Sampling). Soil samples will be collected using a grid sampling process wherein heated headspace screening samples will be collected from landfarm soils at each grid intersection. The exact size of each grid cell will depend on the final landfarm area but will not exceed 20 feet by 20 feet. A photoionization detector (PID) will be used to detect the concentration of volatile organic compounds (VOC) within each screening sample. An analytical sample will be collected from soils determined by the PID to contain the highest VOC concentrations. In total, KIB will collect a minimum of four soil samples (including one duplicate sample) for laboratory analysis. 7.0 TILLING AND SAMPLING SCHEDULE To promote the release of volatile organics, landfill staff will turn over the landfarm soils at least once every two weeks throughout the spring and summer seasons. A small excavator will be used to turn over the landfarm soils in a manner so that underlying soils are not disturbed and mixed with the impacted soils. The gradient of the subbase of the landfarm will be maintained during the landfarming operation. The landfarmed soils will be sampled at the end of the summer (approximately late September) to monitor remediation progress and ultimately confirm that Over -40 -Inch -Zone MTG cleanup levels have been achieved. Sampling will follow the same process as outlined in Section 6.0 (Baseline Contaminated Soil Sampling). All samples will be analyzed for the analytes discussed in Section 4.0 (Background Soil Sampling). 8.0 REPORTING An interim report will be provided to the ADEC no later than 90 days after of the end of the landfarming operation for the year. The report will contain the analytical results for the end -of -season sampling of the landfarmed soil and a comparison with the analytical results for the baseline sampling of the contaminated soil. If the analytical results of the end -of -season sampling confirm that contaminants are not yet below the Over -40 -Inch Zone MTG cleanup levels, KIB will plan to continue tilling the landfarm the following season, perform further sampling, and provided a report to ADEC at the end of the year. If the analytical results of the end -of -season sampling confirm that contaminants are below the Over -40 -Inch Zone MTG cleanup levels the KIB will request approval from the ADEC to close the site. Once the soil is determined to be under cleanup levels it is KIB's intent to use it as cover in the lined landfill cell, in coordination with the ADEC Solid Waste Program. Kodiak Island Borough Page 6 Kodiak Island Borough Landfill Landfarm Work Plan November 2019 9.0 CONCLUDING REMARKS This Plan provides details for treating approximately 71 cubic yards of PCS excavated around a UST at the Kodiak Island Borough Landfill. The logical and cost-effective method for treating the soil is by the method of landfarming. The KIB will contract with a QEP to collect soil samples from the proposed site before landfarm construction to establish background soil analytical data. Following the construction of the landfarm and spreading of the contaminated soil, the designated QEP will collect samples from the contaminated soil to establish baseline analytical concentrations. Turning over of the landfarm will occur a minimum of once every two weeks to maximize exposure of the soil to oxygen and expedite the biodegradation and volatilization of the petroleum hydrocarbons and BTEX compounds. The landfarm will be sampled at the end of the landfarming duration for the year (approximately late September) to monitor remediation progress and ultimately confirm that cleanup levels have been achieved. The KIB will provide the ADEC with a progress report at the end of each landfarming operation for the year. In the case of unforeseen circumstances, the KIB will coordinate with the ADEC during landfarm construction and for additional guidance on screening and sampling methods.

The poly containment liner will be at least 20 mil thickness. Sacrificial sand will be used to protect the bottom liner during loading and unloading of the contaminated rock. The sand layer will be no less than 6 inches in depth. Outer berms will consist of a clean fill boom that will protect the perimeter and prevent runoff from the landfarm. The base of the cell will be placed on the existing grade, but the boom will contain the contamination within the foot print of the treatment area. Contaminated soil will be screened to remove any rocks 2" or larger. The material will be placed within the land farm and kept within the perimeter of the cell. Once screened, we anticipate that the total depth of material to be no more than 24 inches thick (with the sacrificial sand the total depth of material would be 30 inches). The materials will be added to the cell via excavator, and the materials will be spread by either tracked earth moving equipment or by hand shoveling. Great care will be taken to not tear the liner or disturb the poly liner or sand. If the liner is damaged, it must be repaired so that leachate is contained. On days with inclemate weather or pending precipitation, the cell will be covered with poly that is at least 6 mil thickness (preferably clear poly) and will be opened during periods of good weather. Soil or similar material will be placed on the poly cover to keep secured. An example of this construction is depicted in Figure 1. Figure 1. Landfarming Example The proposed location of the land farm will be on the east side of KIB Landfill designated in Figure 2. This area is approximately 150 feet by 40 feet, but size will ultimately be determined by the quantity of material remaining after the screening efforts are completed. Figure 2.

The KIB is seeking approval for this landfarming plan as the corrective action for the workplan submitted in response to Spill 18249925501. Once the addendum is approved, additional time will be required for the KIB to seek budget approval for funds associated with clearing the land necessary for the landfarming operation. Assuming budget approval is granted, corrective action in accordance with the previously submitted workplan can begin, incorporating the additional work addressed in this addendum to construct and fill the referenced land farming cell. Corrective Action will include the regular maintenance of the soils in the land farming cell. Soils will be monitored on a bi-annual basis (spring and fall) via PID screening. Soil samples will be gathered using surface soil collection methods outlined in the ADEC Field Sampling Guidance. ADEC Standard Operating Procedures outlined in the Guidance document will be used for collection, handling, quality assurance/quality control, and data reporting. Soil samples will be analyzed by SGS North America in Anchorage, AK. Monitoring will begin with the collection of characterization samples. The land farm cell will be divided into a grid of 10'x10' areas. Each grid area will be screened and two samples will be taken from the grid areas with the highest PID reading. Screening will occur once per year until which point all PID readings are below the action level of 10 ppm. Interim reports will be submitted following each screening event. When screening indicates that levels in the land farm are below the most stringed ADEC cleanup levels, based on the aforementioned action level, confirmation samples will be done. For confirmation samples, all QA/QC procedures will be done. Once final report has been submitted to all divisions and soil has met all clean up level requirements soil will be used as cover at the landfill.

ECSEnvironmental, Occupational Safety and Industrial Hygiene Services ADEC Spill Response and Prevention 24 September, 2018 PO Box 111800 Juneau, AK 99811 ATTN: Alyssa Murphy via email: alyssa.murphy@alaska.gov Ms. Murphy, On September 10th, 2018 Environmental Contracting Solutions, Inc. provided a Qualified Environmental Professional (QEP) for the oversight of an underground storage tank (UST) removal at the Kodiak Island Borough (KIB) Landfill Baling Facility. During excavation, soil contamination was discovered and investigation into the extent of the contamination ensued. This report details the field activities and findings of that investigation and provides recommendations for the closure of spill report #18249925501 that was filed by the Borough on August 10, 2018. The full lab analytical report, previous ADEC findings with regard to groundwater at the site , environmental impact assessment, and conceptual site model (CSM) are attached to this report in support of recommendations. Background Environmental Contracting Solutions, Inc. (ECS) was contracted by the KIB on September 7th, 2018 to act as a QEP providing oversite for the decommissioning by removal of an unregulated UST at the Borough's Landfill Baling Facility. The removal of the UST was prompted by the identification of what was believed to be a small fuel spill which was reported to the Alaska Department of Environmental Conservation (ADEC). The spill number for this report is 18249925501. The spill was believed to be the result of a release from a breach in one of the ventilation pipes during filling of the UST. The tank was confirmed to be a non-regulated tank and the Borough received authorization from ADEC to proceed with the tank removal. Removal operations commenced on September 10th, 2018. As excavation around the tank progressed, it became apparent that the extent of the spill was greater than originally thought. The tank was removed at approximately 1500 on September 10th. Excavation continued on September 11th in order to further determine the extent of the subsurface contamination. On September 12th, excavation was halted for safety reasons and physical limitations on three sides of the excavation. An electrical conduit located on the west side of the excavation, the Baling Facility on the north side, and a rock shelf/ earthen hill on the east side. Excavation further to the east into the hill had started to exhibit signs of instability and sloughing of the soil due to the steep slope. A teleconference was held with ADEC to review actions take so far and request feedback and further direction. A site sketch, photos, and a brief summary of the UST decommission activities were compiled and provided to ADEC. At the direction of ADEC and in accordance with sampling guidance, samples were taken from the sidewall/pit bottom interfaces on all sides of the excavation pit as well as from the center of the pit bottom directly underneath where the former tank had been located.

Andrew Devries, of ECS, was the Qualified Sampler that conducted the soil screening of the supersacks in preparation for characterization sampling. Samples from the supersacks were collected by Monique Lewis. Soils collected from the excavation were screened and placed in 1 cubic yard lined super sacks. Screening was conducted as frequently as every cubic yard but no less than one screening measurement every 10 cubic yards throughout the excavation activity. PID Calibration Soil screening data was collected using a Mini -Rae 2000 Photoionization Detector (PID) supplied by ECS. Screening was performed utilizing a direct read method. The PID was calibrated on site prior to use each morning, at mid-day, and at the end of each day (See Table 1 for PID calibration data). Calibration was performed with 100 ppm (parts per million) isobutylene.

MK performed the removal of the UST and subsequent excavation of the soil beneath the UST as part of the determination of the extent of soil contamination. Soil screening was performed near the top of the tank approximately 2 feet below ground surface (fbgs) at the location of the fill neck and the two fuel lines. Table 2 provides details of the frequency of soil screening and readings obtained while excavating around the UST in preparation for removal. Figure 1 illustrates the grid used in Table 2. Figure 2 illustrates the site and location of the UST with reference to the surrounding structures and geographic features. 35 Cubic yards of material were removed from the excavation pit on day 1. Supersacks were placed on a 10 -mil polypropylene liner near the excavation. P.O.

A concrete pad of an approximate area of 32 square feet was discovered at approximately 10 fbgs which served as a foundation for the UST. MK used a jack hammer attachment to the excavator to break up the concrete pad for later removal. The pad had an uneven thickness and large pieces of concrete were cleaned off and separated for disposal. Soil was placed in lined supersacks which were then placed on the liner along with the supersacks collected the previous day.

ECSEnvironmental, Occupational Safety and Industrial Hygiene Services Day3: On September 12th, excavation continued to remove as much of the contaminated soil as possible given the constraints of buildings to the north, and rock shelf to the east. Care was also taken to avoid the electrical conduit running from the building along the western edge of the excavation pit. Limits of excavation were reached at approximately 1100 on day three. The stability of the earthen hill on the east wall was in question as loose soils had already started to slough into the excavation. No further excavation to the North could be accomplished without undermining the structural stability of the Landfill Baling Facility. Excavation to further depths would have required benching that would have compromised the electrical and airline conduits running along the west wall of the pit. PID readings on the South and West walls indicated that the presence of contaminated soils along those walls had been greatly reduced and could potentially be below clean up levels. Table 3 details the PID readings and locations for soil excavated on Day 3. ADEC was contacted to update the status of the corrective action to the reported spill and to discuss options given the constraints. A summary and photos were sent to Ms. Alyssa Murphy by KIB E/F Assistant Director, Dave Conrad.

SGS retrieved the samples from Alaska Air Cargo in Anchorage. Laboratory analytical reports indicated detectable levels of DRO, RRO, and BTEX analytes in all samples taken from the pit and from the supersacks. The DRO contaminant was present at levels above the most stringent ADEC cleanup standard for the protection from migration to groundwater (MGW) in all samples except for sample SP -W taken at the west sidewall/base interface. The Total Xylenes contaminant was detected at levels above the MGW cleanup levels at the north wall and the excavation base. Naphthalene was detected above the MGW cleanup levels in the sample taken from the interface of the North wall and base. The contaminants DRO, Ethylbenzene, and Total Xylenes were detected above the MWG cleanup levels in samples taken from the supersacks. The contaminants 1- and 2- Methylnaphthalene and Naphthalene were also detected above MWG cleanup levels in these same samples. None of the aforementioned samples exceeded the ADEC cleanup standards for ingestion, inhalation, or human health. Tables 6 and 7 provide a summary of the sample results.

ECSEnvironmental, Occupational Safety and Industrial Hygiene Services Conclusions and Recommendations While the presence of several analytes are detected above the most stringent cleanup levels for the above 40 inch zone migration to groundwater protection standard, none of the analytes exceed the less stringent thresholds designated for the impacts that would be most relevant at this site. There is very little, if any, chance that contaminants from this excavation site would migrate to groundwater or surface water. The site is where the Kodiak Island Borough Landfill resides and as such was designed to prevent runoff and release of potential contamination from various sources into surrounding water bodies. There are no drinking wells within several miles of the site and those that are located in the vicinity are on an upward slope in relation to the target site. In a memo dated October 9th, 2006, ADEC agreed with the KIB environmental specialist that no groundwater was present at the KIB landfill site. The memo sited a 1985 geotechnical and hydrological investigation that found no saturated zones in or around the KIB landfill. Monitoring wells are installed at the landfill and continue to monitor surface water. The referenced memo is included as Attachment 2 to this report, and the full Monitoring Plan is available upon request. Further, due to the subsurface slope of the strata which follows the surface topography (See Attachment 3, Page 6 topo map), any subsurface contaminants captured by groundwater would tend to migrate in a westward direction toward the unlined portion of the landfill. This portion of the landfill consisted of solid waste placed in a ravine that sloped from the south towards the north. It is likely that groundwater impacted by the residual contaminants in the UST excavation would follow the underlying bedrock topography and ultimately be collected by the landfill leachate collection and conveyance system at the north end of the ravine. Leachate collected from the landfill is treated by an onsite treatment plant and the treated effluent is discharged into the wetland on the property. More importantly, monitoring wells on the west side of the landfill footprint would provide an indication if any residual contaminants had migrated past the western limits of the landfill footprint. The west wall of the excavation was the only area of the excavation where residual contamination was below MWG cleanup levels, which leads to the conclusion that further migration is unlikely. Finally, there are no identified preferential pathways for human exposure where contamination still exists. The most likely scenario based on investigation of the current site conditions and discussion with employees about site history, is that the majority of remaining contamination is and will remain concentrated in the northeastern area of the excavation pit. Any potential human exposure pathways that currently exist will be rendered incomplete in the near future with the addition of a new concrete slab that is planned to be poured directly over the excavation site where contamination was found. For a more thorough analysis of the pathways, see Attachment 2 — Conceptual Site Model. It is our recommendation and request that ADEC approve closure of spill number 18249925501, pending the development and approval of a mitigation workplan for the 71 cubic yards of excavated soil currently stored in lined supersacks. At present the supersacks are contained within a 10 -mil polypropylene liner and covered with the same liner to prevent any water intrusion. P.O.

Ms. Mitchell, On September 26, 2006, the Department of Environmental Conservation (DEC) received your letter stating that there is no groundwater underlying the Kodiak island Borough (KID) landfill. DEC agrees that the water being sampled in the three sampling wells at the landfill can not be characterized as groundwater. Groundwater, by definition, is water found in the zone of saturation, where pore spaces are filled with water. It does not appear that a saturated zone is present near the K03 landfill. A geotechnical and hydrological investigation, reported in a January 1985 document, included seven borings and -11 test pits. This study found that bedrock near the landfill is only a few feet below ground surface (1.5 to four feet). While there were seeps and some water present, no saturated zone was found in this study. Although the sampling wells do not appear to contain true groundwater, it is important that the water in these wells continue to be monitored to ensure detection of any potential impacts from the landfill. DEC believes that the water in the sampling wells at the K03 landfill should be characterized as surface water. The sampling wells must be incorporated into the surface water sampling program. Please add these-tthm sampling locations as points of compliance to your surface water monitoring program. Sampling should be conducted on these, and other surface water sites, as specified in the July 27, 2006 Monitoring Plan for Surface Water. If you have any questions, please contact me at (907) 269-7626 or by e-mail at Sarin-Hendrickson@dec.state.ak us.

So that the KIB can continue to meet the waste disposal needs of the community, KIB proposes to expand the existing landfill on KIB-owned property. The KIB will also be devising a system for storage and containment of leachate, to include capturing leachate seeps currently released to the environment. Proposed Project The new lateral landfill expansion will encompass approximately 10 acres and will have an anticipated lifespan of approximately 40 years. The expansion will be lined with a geocomposite liner and will include leachate collection and storage facilities. The leachate will be treated before release to the environment. Several options are still being considered for how and where the leachate will be treated. The expansion area has been divided into cells to allow phased construction and operation. KIB has decided to break the construction into two phases, and this EID is to cover both phases. Phase 1 of the work will be conducted from August, 2011 to March, 2012 and will include clearing, grubbing, excavation, and access road construction. Approximately 130,000 cubic yards (CY) of soil will be excavated from the site and stockpiled on site for later use as waste cover material during landfill operations. The second phase of the work will be conducted from March, 2012 through September, 2013 and will include construction of the liner and leachate collection systems, and the leachate treatment facilities. See Figure 1 for a site vicinity map and Figure 2 for the landfill and expansion areas and stockpile locations. In general, the proposed sequence of work is: 1) pre -construction activities; 2) mobilization and set-up; 3) clearing, grubbing, drainage earthwork; 4) construction of the liner and leachate collection system; and 5) construction of the leachate collection facilities. The landfill area will be graded to promote drainage and storm water management. Permanent and temporary erosion and sediment controls will be in place during and after construction. The anticipated workforce to complete construction is approximately 10 people. The workforce is not expected to significantly increase for daily landfill operations.

Approximately 13,000 people live in the KIB and the population is not expected to increase significantly over the next three decades (Alaska Department of Labor, 2009). Fishing, the Coast Guard, and tourism represent the major employers. The construction footprint of the proposed cells will remain on KIB property. Approximately half of the development area is already cleared and was used as a borrow area. The other half of the development area is forested uplands. A portion of the future leachate storage lagoon occurs in the adjacent Greenbelt property. This use is allowed in the Greenbelt. The KIB Landfill Greenbelt Ordinance is included as Attachment 1. There are no unique areas identified. The forested areas adjacent to the landfill are not unique to Kodiak. The site has been operating as a landfill since the 1950s. The nearest neighbor is the sawmill on the adjacent property, 0.1 miles to the northeast. Evaluation of Alternatives Several alternatives were considered before selecting the current site for the proposed landfill expansion. The no -action alternative would necessitate the closure of the existing landfill once it reaches capacity in 2014. Kodiak would still need to find another place to put its waste. Other options considered included continuing landfill operations, incineration, and transport to an out of state landfill (Bell & Associates, Aug 2008). It was determined that an incineration facility would likely be unable to cover high operating and capital costs without significantly increasing tipping fees. Exporting of waste was not pursued due to high and unpredictable costs, as well as potential environmental issues associated with shipping wastes over open water. Continuing the current landfill was selected as the most cost effective option. Several alternative sites to the one selected were also evaluated in 1997-98 (CH2M HILL) and in 2008 (Bell & Associates). Development of the adjacent area on KIB property was selected as optimal for continuing landfill operations due to least impact to the environment and lowest cost to the KIB. Environmental Effects Associated with the Proposed Action Direct environmental impacts of this project include clearing of forested areas. No indirect impacts are expected. Unique sensitive environmental areas will not be affected by this project - there will be no construction in wetlands, the area is not in the flood plain, and there are no agricultural lands in the area. The proposed site is within the coastal zone. There is an approved Coastal Zone Management Plan for the Kodiak Island Borough, of which the KIB landfill has historically been a part. There are no wild and scenic rivers in the ANC/KODIAK LF-ADEC ENVID.DOCX a a�LL ADEC ENVID KIB LANDFILL LATERAL EXPANSION - CLEARING, EXCAVATING, FENCING 11111� area. The area around the landfill is not a sole source aquifer area nor is it a Wellhead Protection Area. There are no known historic sites on or near the construction site. The nearest protected state area for birds, mammals, fish, or shellfish is Tugidak Island, over 113 miles away (straight-line distance).This critical habitat would not be affected by work on this project. Monitored species and essential fish habitat (EFH) in the Kodiak area include Ground Fish in the Gulf of Alaska, Salmon in the Gulf of Alaska, and the Scallops statewide fishery. This project will have no adverse effect on EFH. There are four federally threatened or candidate species which could potentially be affected by this project: the Stellar's eider, the northern sea otter, Kittlitz's murrelet, and the Yellow - billed loon. Concern for these species is related to animals feeding from offshore areas with contaminated water. All construction equipment and constructed facilities will be contained at the landfill site on KIB property (an existing industrial site) which contains no habitat for any of the listed species. Water handling plans and appropriate discharge permits will be generated if water is handled. Any stormwater associated with this project will be controlled as directed in the Stormwater Pollution Prevention Plan (SWPPP) to mitigate the release of contaminants to the environment. The proposed project will not destroy or adversely modify critical habitat for any of the listed species in the action area. KIB is aware of one incident where a bald eagle was injured by an old fishing line and hook pulled from the landfill. Since this incident, landfill operations staff has added fishing gear to their list for screening of incoming waste. Incoming waste with fishing gear, netting, hooks, etc. is now handled separately and is covered immediately so that the eagles cannot reach it. The proposed lateral expansion of the KIB Landfill is irreversible. However, the resources to be impacted are not unique to the area and occur on KIB-owned property. Long-term use of this property will be affected by this expansion, however, the impacts of developing an entirely new area for use as a landfill would be greater than expanding an existing one. Steps to Minimize Environmental Impacts During construction, the construction contractor will be responsible for maintaining and implementing a SWPPP. The construction contractor will review, update, and submit the SWPPP and Notice of Intent (NOI) to discharge stormwater under the APDES Construction General Permit to the Alaska Department of Environmental Conservation. The SWPPP will be complete with measures such as silt fences and straw wattles to protect the surrounding environment from construction erosion runoff. The draft SWPPP, prepared by CH2M HILL for this project, is included as Attachment 2. There are no known policies or legal constraints that would prevent construction of this landfill expansion. Public Participation There have been many opportunities for public comment throughout the planning stages of the landfill expansion. There was a public participation phase included when the 2008 Solid Waste Management Plan was being developed. This expanded area was presented as an option. Since the time of the selection of Cells 1 and 2 for immediate expansion, CH2M HILL has completed two presentations to the KIB Assembly. Each of the Assembly ANC/KODIAK LF-ADEC ENVID.DOCX 5 9 amu ADEC ENVID KIB LANDFILL LATERAL EXPANSION - CLEARING, EXCAVATING, FENCING 4IM meetings is open to the public and provides an opportunity for public comment on the proposed project. There will also be a 30 -day public comment period on this EID. Reasons for Concluding There Will Be No Significant Impact The planned improvements will be constructed on landfill property approximately 0.3 miles from the coastline. The proposed action is not expected to impact any adjacent properties, waters, or neighboring communities. • There will be no increase in volume of discharge or loading of pollutants from the system to the receiving waters. The proposed leachate treatment system will decrease the pollutant loading to receiving waters. • This project will not create a new discharge to surface or ground waters. • This project will have no effect on archeological or historical sites, endangered or threatened species or their habitat, or environmentally important natural areas (i.e., floodplain, wetlands, and recharge zones). • This project is not expected to have a significant adverse effect on the quality of the environment, individually or cumulatively over time or in conjunction with any other action. Agency Comments Responses Joan Dale of the Survey and Inventory Division of the State of Alaska Office of History and Archaeology and Historic Preservation was contacted on 5/4/11. She was given the project location (Township, Range, and Sections) and indicated that there were no reported sites in that area based on the Alaska Heritage Resources Survey Database. The U.S. Fish and Wildlife Service was contacted on 6/27/11. Kimberly Klein, Endangered Species Biologist, responded with the concerns listed above in "Environmental Effects Associated with the Proposed Action." A formal response to their concerns will be submitted on 7/11/11. Consultation with USACE is under way. No construction is planned in wetland areas. The proposed project is not expected to cause significant public controversy about potential environmental impacts. No concerns were raised in either of the public meetings. The KIB Landfill Lateral Expansion is not associated with any other projects known to have potentially significant environmental impacts. The proposed project is not expected to conflict with any laws or regulations.

Exposure Pathways: (The answers to the following questions will identify complete exposure pathways at the site. Check each box where the answer to the question is 'yes a) Direct Contact - Incidental Soil Ingestion Are contaminants present or potentially present in surface soil between 0 and 15 feet below the ground surface? (Contamination at deeper depths may require evaluation on a site-specific basis.)

A silt screen has been placed on the material at and clean imported soil used to backfill. Pathway is marked incomplete based on the surface soil tion of less than 2fbgs. Incidental ingestion of contaminated soil is highly unlikely. 2. Dermal Absorption of Contaminants from Soil Are contaminants present or potentially present in surface soil between 0 and 15 feet below the ground surface? (Contamination at deeper depths may require evaluation on a site specific basis.) F Can the soil contaminants permeate the skin (see Appendix B in the guidance document)?

If both boxes are checked, label this pathway complete: Incomplete Comments: No groundwater was encountered during excavation and is unlikely to be encountered at the site (See ADEC memo dated 9 October, 2016 in Attachment 2). There are no drinking water sources within a mile of the facility. revised January 2017 2. Ingestion of Surface Water Have contaminants been detected or are they expected to be detected in surface water, or are contaminants expected to migrate to surface water in the future? Could potentially affected surface water bodies be used, currently or in the future, as a drinking water source? Consider both public water systems and private use (i.e., during residential, recreational or subsistence activities). If both boxes are checked, label this pathway complete: Incomplete Comments: Monitoring wells exist on the site and would provide early warning in the unlikely event migration occurred that could potentially impact surface water. The nearest surface water is over 500 yards north of the excavation site. This is the leachate treatment wetlands. Any contamination would be stopped by the leachate treatment process at the landfill. Surface water in this area is not utilized for drinking water. 3. Ingestion of Wild and Farmed Foods Is the site in an area that is used or reasonably could be used for hunting, fishing, or harvesting of wild or farmed foods? Do the site contaminants have the potential to bioaccumulate (see Appendix C in the guidance document)? Are site contaminants located where they would have the potential to be taken up into biota? (i.e. soil within the root zone for plants or burrowing depth for animals, in groundwater that could be connected to surface water, etc.) If all of the boxes are checked, label this pathway complete: Incomplete Comments: contamination exists far below the root system of any plants. The property is a government owned lity that is fenced on all sides and not used for hunting, farming, or recreation. There are no contaminants Sent at have the potential to bioaccumulate. c) Inhalation - 1. Inhalation of Outdoor Air Are contaminants present or potentially present in surface soil between 0 and 15 feet below the ground surface? (Contamination at deeper depths may require evaluation on a site specific basis.) Are the contaminants in soil volatile (see Appendix D in the guidance document)? If both boxes are checked, label this pathway complete: Incomplete Comments: )acted soils have been removed to a level of 10fbgs. A silt screen has been placed on the material at that el and clean imported soil used to backfill. Using the surface definition of < 2fbgs, this pathway is :)mplete. Xylenes up to 4mg/kg & Naphthalene at 0.887mg/kg remain @ 10fbgs of clean soil. It is highly ikely that vapors at these levels would volatize through 10 feet of clean soil. C revised January 2017 2. Inhalation of Indoor Air Are occupied buildings on the site or reasonably expected to be occupied or placed on FX_ the site in an area that could be affected by contaminant vapors? (within 30 horizontal or vertical feet of petroleum contaminated soil or groundwater; within 100 feet of non -petroleum contaminted soil or groundwater; or subject to "preferential pathways," which promote easy airflow like utility conduits or rock fractures) Are volatile compounds present in soil or groundwater (see Appendix D in the guidance FX_ document)? If both boxes are checked, label this pathway complete: Complete Comments: ie baling facility is within 30 feet of the contaminated area, however the likelihood of any affect from vapors minimal. The contamination is 10fbgs and will soon be covered with a concrete slab. The facility is open id well ventilated while workers are present. 4 revised January 2017 3. Additional Exposure Pathways: (Although there are no definitive questions provided in this section, these exposure pathways should also be considered at each site. Use the guidelines provided below to determine if further evaluation of each pathway is warranted.) Dermal Exposure to Contaminants in Groundwater and Surface Water Dermal exposure to contaminants in groundwater and surface water may be a complete pathway if: o Climate permits recreational use of waters for swimming. o Climate permits exposure to groundwater during activities, such as construction. o Groundwater or surface water is used for household purposes, such as bathing or cleaning. Generally, DEC groundwater cleanup levels in 18 AAC 75, Table C, are deemed protective of this pathway because dermal absorption is incorporated into the groundwater exposure equation for residential uses. Check the box if further evaluation of this pathway is needed: Comments: Inhalation of Volatile Compounds in Tap Water Inhalation of volatile compounds in tap water may be a complete pathway if - 0 The contaminated water is used for indoor household purposes such as showering, laundering, and dish washing. o The contaminants of concern are volatile (common volatile contaminants are listed in Appendix D in the guidance document.) DEC groundwater cleanup levels in 18 AAC 75, Table C are protective of this pathway because the inhalation of vapors during normal household activities is incorporated into the groundwater exposure equation. Check the box if further evaluation of this pathway is needed: Comments: F revised January 2017 Inhalation of Fugitive Dust Inhalation of fugitive dust may be a complete pathway if - 0 Nonvolatile compounds are found in the top 2 centimeters of soil. The top 2 centimeters of soil are likely to be dispersed in the wind as dust particles. o Dust particles are less than 10 micrometers (Particulate Matter - PMio). Particles of this size are called respirable particles and can reach the pulmonary parts of the lungs when inhaled. DEC human health soil cleanup levels in Table B 1 of 18 AAC 75 are protective of this pathway because the inhalation of particulates is incorporated into the soil exposure equation. Check the box if further evaluation of this pathway is needed: Comments: Direct Contact with Sediment ❑>r This pathway involves people's hands being exposed to sediment, such as during some recreational, subsistence, or industrial activity. People then incidentally ingest sediment from normal hand-to-mouth activities. In addition, dermal absorption of contaminants may be of concern if the the contaminants are able to permeate the skin (see Appendix B in the guidance document). This type of exposure should be investigated if - 0 £o Climate permits recreational activities around sediment. o The community has identified subsistence or recreational activities that would result in exposure to the sediment, such as clam digging. Generally, DEC direct contact soil cleanup levels in 18 AAC 75, Table B 1, are assumed to be protective of direct contact with sediment. Check the box if further evaluation of this pathway is needed: Comments: 6 revised January 2017 4. Other Comments (Provide other comments as necessary to support the information provided in this form) Based on the depth of the contaminants and the nature of activities performed at the industrial site, the potential for complete pathways or exposure are extremely limited. The placement of a concrete pad over the area where contamination is known to exist further limits the potential for exposure. Three of the 5 samples taken are less than 1/10th of the Inhalation clean up limit and two of those samples are less than 1/10th of the Ingestion cleanup limit. The other samples are also below the threshold for these pathways.
