INTRODUCTION Kasteler Consulting, Inc (KCI) has prepared this Environmental Work Plan on behalf of Coldfoot Environmental Services Inc. (Coldfoot) to detail environmental support activities that have been conducted to date at the Seward Orphanage – Jessie Lee Home, Seward, Alaska (herein also referred to as the “site”) and those remaining to be conducted to complete the project objectives. Coldfoot was contracted by the City of Seward (COS) to demolish the site buildings and related utility infrastructure within the building footprints. Coldfoot contracted KCI to assist with the characterization and disposal of petroleum, oil, and lubricant (POL) contaminated concrete and the investigation of other potential environmental concerns such as floor drains, subsurface utility connections (water and septic) and to evaluate for potential soil contamination. Initial investigative findings and soil analytical results are presented below in Section 1.1. Environmental activities covered under this EWP include the excavation and offsite treatment/disposal of POL contaminated concrete and soil contaminated with POL and metals greater than ADEC regulatory cleanup levels at the site so Coldfoot can complete site restoration activities and the property be available for construction of a city park. 1.1. Site Description and Background The property consists of Lots 15A and 15B, Jesse Lee Heights Subdivision, Addition No. 4. Lot 15B is a 72,268 square foot parcel which is primarily accessed off Phoenix Road. The northeast comer of the lot also adjoins Benson Drive. Lot 15A is an 43,449 square foot parcel that is accessed off Benson Drive (2001 COS). In total the site, approximately 2.6 acres in size (Figure 1, Appendix A). The Seward Orphanage, also known as the Jesse Lee Home for Children, was a former home for displaced children. Original construction in 1925-1926 included two dormitories, Jewel Guard Hall and Goode Hall. The Balto Building was added between the two dormitories in 1937 and provided dining space and a large kitchen. The home was operated by the United Methodist Church from its opening in 1926 until the 1964 earthquake after which the Goode Hall building suffered extensive damage, was demolished, and operations were relocated to a new building in Anchorage, Alaska. The following is a list of known owners and projects that have been proposed for the Jesse Lee Home since its closure after the 1964 earthquake (2001 COS). 1965 Alaska Children's Services (Methodist Women's Home Missionary Society) transferred ownership to the City of Seward 1970 Development Corporation of America purchased and proposed development that included condominiums, apartments, and a convention hall - City of Seward had ownership at some point during this time + 1973 Last Frontier Inc. purchased and proposed development of a hotel + 1981 City of Seward had ownership at some point during this time 1984 M&I Partnership (Frank Irick & Mary Bellenir) purchased and proposed development of the home into condominiums and time shares. Frank Irick received a CUP for this project that expired in 1984. 1991 Billy "Blackjack" Johnson started a movement to raise $400,000 to purchase the home, and preserve the site as a historical building/museum +1995 Seward Senior Center proposed to restore the buildings for senior housing.According to Judy Martin, who was the Director of the Senior Center at that time, two engineer 6 2 reviews were completed at that time with conflicting results as to whether the structures could be restored 1996 Daniel Claugus, in agreement with Frank Irick, obtained a CUP for a hotel complex. He obtained two extensions and the CUP expired in 1997. According to a 1998 letter from Mr. Irick, Mr. Claugus was unable to obtain financing. 1998 Frank Irick obtained a CUP for a hotel complex that expired in 1999 1999 Dale Lindsey hired Franklin & Associates, Consulting Engineers, to examine the condition of the building and provide a preliminary opinion as to the feasibility of converting the structure into either a hotel or office building. That evaluation determined that the structure should be considered unstable, and that a significant engineering effort would be required to establish the required structural capacity of the building, The report concluded that, rebuilding the structure will require substantial work and material effort involving all of the basic structural components and will be a relatively expensive undertaking. 2000 Friends of the Jesse Lee Home entered into an agreement with the COS to restore the buildings sometime around 2000. Efforts to restore the Jewel and Balto buildings were made over the years from 2000 on however, after little progress and building deterioration, the City of Seward voted to demolish the buildings in 2020 (Wikipedia). The City of Seward contracted Coldfoot to demolish the buildings in 2020 and work began in the spring of 2021. Upon the request from Coldfoot, a site visit was conducted by KCI in October of 2020 to visually inspect the buildings and evaluate the following environmental concerns prior to building demolition. Photos 1 and 2 in Appendix B present the general as-built building layouts. 1) Floor drains and septic. It was unknown if the buildings were connected to a drain/septic system and the location of the septic system, if present, was not known. The COS indicated the buildings were not connected to city sewer and water utilities. Building basements were inspected for floor drains or other subsurface structures that could potentially be classified as an Environmental Protection Agency (EPA) Class V Injection Well. In the Jewel Building, no floor drains were identified, and all interior drain piping was observed to properly extend through the concrete floor and stem walls. No staining was observed on the concrete floor and no other indication of potential environmental concerns were identified. In southern half of the Balto Building basement, two floor drains were identified, one floor drain provided drainage for a trench drain system and the second was a box style floor drain. The trench drain system was recessed in the concrete floor and formed a rectangle several feet within the room from the foundation wall. The trench drain was full of vegetation debris but appeared to drain into one floor drain (Photo 3, Appendix B). The trench drain system is not seen on the Balto Building as-built map but the floor drain location and drain line to the south are documented. The second floor drain was a square box style floor drain located on the north side of the small room in the southeastern corner of the building and in front of what was likely a service door way (Photo 4, Appendix B). This floor drain is not shown on the as-built map. The drain contained a layer vegetation matter and debris. There was no staining on the concrete floor or potential environmental concerns were identified in the southern half of the building. The northern half of then Balto Building basement contained the buildings boilers, 7 3 mechanical equipment, piping and fuel storage. The concrete floor in the northern half was at a slightly lower elevation compared to the southern half of the building. One potential floor drain was identified on the north side of the eastern boiler where a six in round metal pipe stuck up slightly from the floor (Photo 5, Appendix B). The pipe did not appear to be original as the concrete around it was chipped and previously patched. Heavy fuel staining and a strong fuel odor was present on the concrete in the area. It could not be confirmed if the pipe was a floor drain and was connected to the building drain system. No floor drains are documented in the area on the Balto Building as-built map. A rectangle floor sump was located near the end of the eastern boiler and is documented on the as-built map. A trench drain extended from the floor sump north along the front of the AST containment (Photo 5, Appendix B). 2) Above Ground Storage Tanks (ASTs). Two 2,000-gallon ASTs were present in the basement of the Balto building along with two smaller 400-gallon ASTs. The two 2,000-gallon ASTs were located within a concrete containment that also served as part of the building’s exterior foundation and interior wall supports in the northwest corner of the building. Several inches of black tar from what was suspected to be Bunker C mixed with fuel oil and debris was present on the concrete containment floor area (Photos 6 and 7, Appendix B). The ASTs contained several hundred gallons of fuel oil each. The two smaller ASTs located on stands outside of the containment along the western foundation wall were 400 gallons in size and empty. Tar and oil surface staining on the concrete floor was present on the floor area around the two smaller ASTs. Various configurations of fuel piping extended from the ASTs to the boiler area. 3) Contaminated concrete: Tar and oil surface staining on the concrete floor was present in the area around the boilers. During the spring of 2021 Coldfoot completed abatement and demolition of the Jewel and Balto structures except for the concrete building foundations. The ASTs in the Balto building and any remaining fluids were removed by Coldfoot and delivered to U.S Ecology in Anchorage for cleaning and recycling. This included the oil, fuel, debris sludge mixture from the cleaning and scraping of the AST containment floor. On June 5th and 7th, 2021 KCI conducted preliminary visual inspections and evaluation of concrete building foundations and drains for environmental site concerns with Coldfoot. An excavator was used to break apart and remove sections of the buildings concrete foundations to chase and expose buried utilities, segregate visually contaminated vs non contaminated concrete and to aid in the collection of soil and concrete characterization samples. Soil and concrete characterization samples were collected by an ADEC Qualified Environmental Professional, as defined in 18 AAC 75.333 and 18 AAC 78.088, following the Alaska Department of Environmental Conservation (ADEC) Field Sampling Guidance (FSG) collection methods. The samples were submitted to SGS Environmental Services, Inc. (SGS) in Anchorage for analysis following standard chain of custody procedures. Sample analysis included the following methods: • Benzene, toluene, ethylbenzene, and xylene (BTEX) EPA SW-486, Method 8260B • Volatile Organic Compounds (VOCs)-EPA SW-486, Method 8260B • Gasoline Range Organics (GRO) -State of Alaska Method AK 101 8 4 • Diesel Range Organics (DRO) -State of Alaska Method AK 102 • Residual Range Organics (RRO) -State of Alaska Method AK 103 • Polycyclic Aromatic Hydrocarbons (PAHs)-EPA SW-486, Method 8270 SIMs • Resource Conservation and Recovery Act (RCRA) in 40 Code of Federal Regulations (CFR) metals (Total and TCLP) analysis by Method SW-6020 and SW 1311/6020. The sample results were compared to ADEC’s Method 2 soil cleanup levels as outlined in ADEC regulations 18 AAC 75.340, Tables B1 and B2, Under 40 Inch Zone, Migration to Groundwater and RCRA criteria. Project features were surveyed to provide spatial reference information for figure generation, and to document soil sample locations. A RS Geospatial LT500T handheld GPS receiver with submeter accuracy was used to complete the survey. Soil sample locations, select results and investigate findings are presented in Figure 2 and Figure 3 (Appendix A) for the Jewel and Balto Buildings respectively. Basic as-built images provided by the City of Seward for the Jewel and Balto Buildings were used as a guide and updated with the actual utility locations as identified during the inspections (Photos 1 and 2, Appendix B). Investigative findings and associated soil sample analytical results for each building are detailed in the following sections and corresponding photographs are presented in Appendix B, Photographic Log. The project sample summary log is presented in Appendix C. The SGS analytical data package is presented in full in Appendix C. A Level 2 Chemical Data Review with qualified data tables and the ADEC checklist were completed by Sustainable Earth Research and are presented in Appendix D. 1.1.1. Balto Building The following sections detail the Balto Building environmental investigation findings and analytical soil sample results. Boilers, Floor Sump and Fuel Piping Area Investigation activities began with the demolition of the floor sump and the surrounding concrete pad in front of the boilers in what was the Balto building basement. The floor sump was a box approximately 35 x 28 inches in size that was recessed 24 inches below the surrounding concrete floor. A metal pipe elbowed 90 degrees into the sump on the western wall from an unknown source (Photo 8, Appendix B). The concrete floor in the area around the floor sump and the front of the boilers had visual and olfactory indication it was fuel contaminated and therefore was segregated and containerized onsite in a 20 cubic yard dumpster. Removal of the concrete pad around the sump and the piece of pipe that was a potential floor drain, exposed a lower concrete building foundation approximately 10-foot square that contained fire brick/brick from old furnaces, debris, fuel piping and visibly fuel contaminated soil and tar material. It appeared an older building was partially demolished and covered during construction of the concrete floor of the Balto Building (Photos 9 -12, Appendix B). A soil sample (21SW-01-SO) was collected below all the building debris layers in non-visibly stained soil at a depth of approximately 36 inches below the original concrete pad elevation to vertically delineate the potential depth of soil contamination (Photo 13, Appendix B). Soil sample laboratory analysis included VOCs/BTEX, DRO/RRO and PAHs. The sample had a detection for DRO greater than the ADEC cleanup level of 855 mg/kg. Soil sample 21SW-02-SO was collected above the previous sample but under the fuel lines to characterize the black tar like 9 5 material in the fire brick area. Laboratory analysis included VOCs/BTEX, DRO/RRO, PAHs and total RCRA metals. The sample had detections of DRO, Arsenic, Mercury, and Benzene greater than the ADEC cleanup levels. In addition, the pipe elbow visible in the sump wall was exposed along with 5 other sections of fuel piping of various dimension/length that extended under the concrete slab to the former ASTs in NW corner of the Balto building (Photo 14, Appendix B). One length of ½ inch pipe still contained some fuel/water mix which was drained into absorbent pads. All pipe sections were removed for disposal. Soil sampling was not conducted in this area because clumps of Bunker C contaminated soil are present along the entire length of the larger 2” piping however it visually appeared limited to the pipeline corridor. All concrete removed from the floor in this area was visibly contaminated and was also containerized in the dumpster. AST Containment The AST containment area was a concrete room that housed two x 2,000-gallon ASTs and was also part of the building foundation. The western concrete wall inside the building was several feet high to create a containment that was accessed by ladder. A layer of hard black tar remained on the floor and on the lower portion of some of the walls after the ASTs were removed and the area scraped and cleaned by Coldfoot. KCI observed the demolition of sections of the lower tar covered portions of the concrete containment walls/building footer and the containment floor. The tar layer on the floor was up to ¼ thick and the tar seeped down through several cracks in the floor and along the perimeter of the containment where the floor and wall concrete met. The soil contamination below the concrete floor appeared to generally isolated to these locations where thick globs of tar were present on the soil. The tar on the wall/footings was a thin >1/8 layer on the first 12 to 16 inches of wall and areas along the floor joint where the tar seeped through. Suspected fuel contaminated/Bunker C coated concrete was segregated using the excavator and picked by hand for smaller pieces and placed into the 20-cy dumpster (Photos 16 to 19, Appendix B). A concrete sample (21SW-10-CO) was collected from the containment floor to characterize the fuel contaminated concrete to guide disposal. Sample analysis included DRO/RRO, PCBs and Total RCRA Metals. The sample had a detection of 2,890 mg/kg for DRO, 3,060 m/kg for RRO, non- detect for PCBs and below RCRA action limits for TCLP metals. Soil sample 21SW-05-SO was collected from soil under the concrete in the center of the containment floor to evaluate for soil contamination in an area that did not have tar. The sample did not have any detections above ADEC cleanup criteria. The excavator dug test pits on the outside of the northern and eastern walls of the containment to a depth below the containment floor (Photo 20, Appendix B). Two soil samples were collected to characterize/verify soil contamination did not extent out of the containment footprint on the north and eastern walls. The northern sample (21SW-04-SO) did not have detections above ADEC cleanup criteria but the eastern soil sample, 21SW-03-SO, had a detection of DRO at 264 mg/kg, just above the ADEC cleanup level of 250 mg/kg. Floor Drains and Piping The building floor drains, and sewer/drain lines were exposed with an excavator and traced to the edge of the building. Two drain systems were present in the Balto Building, a ductile iron drain system and a ceramic drain system. The ductile iron drain system began adjacent to the stairs on the western side of the building. Upper floors drained into the main line that completed several 90- 10 6 degree bends around the southwestern basement room concrete slab before exiting the building. A separate line from the Jewel building also entered the Balto building on the western side and connected to the main drain line. The ductile iron drain system was removed to the edge of the building on the southern wall where it was plugged with spray foam. All the ductile drain lines were well connected without any breaks or evidence of leaks. A lower ceramic drainpipe 8 to 10 inches in size was also identified below where the ductile drainpipe was capped. The ceramic pipe appeared to be oriented NW-SE but was not traced (Photos 21 to 25, Appendix B). The ceramic drain system of the Balto building included a floor drain box near the SE corner of the building (not seen in the as built) (Photo 24, Appendix B) and the single drain near the south-central portion of the build associated with the floor trench drain system. The drain box had a 5 inch ceramic drain pipe which extended 25 ft from the drain box South-Southwest, then made an almost 90 degree turn into a larger ceramic drainpipe which then connected to the 12” ceramic drainpipe on the southern building wall below the Balto Building drain. The 5” drainpipe was observed to be dry, without contents and did not have an odor or indication of potential contamination. No indication of soil contamination was identified around the box/drainpipe origin, but a soil sample was collected (VOC/BTEX, DRO/RRO, PAHs and RCRA metals) for confirmation. The sample was non-detect for almost all compounds. The second floor drain opening was not located but the ceramic piping was uncovered. The piping appeared to have been all intact up to the edge of the building and there was no indication of soil contamination (Photo 25, Appendix B). 1.1.2. Jewel Building The following sections details the Jewel Building environmental inspection findings and analytical sample results. Floor Drains and Piping The Jewel Building floor drains and sewer/drain lines were exposed with an excavator and traced. All floor drains and drain lines located within the building footprint consisted of ductile iron and were well connected without any breaks. From the center of the building the lines drained to the west and east due to the different elevations of various parts of the building. The portion that drained to the east was all ductile pipe until the drainpipe exited the eastern side of the building where it transitioned to ceramic pipe which extended to the Balto building where it again connected to ductile pipe when it entered the Balto building (Photos 27 to 29, Appendix B). The western half of the drain system exited the building at the west wall just north of the former stairs. This half of the drain system was also ductile iron pipe inside the building but was identified to connect to a 7” wood stave pipe outside the building. A ceramic 4” drainpipe was also identified above the wood stave pipe (Photo 30 to 34, Appendix B). The two lines extended along the building footer to the south but the termination points of the two pipelines past the building edge were not determined. This half of the drain system was also intact, in good condition and there were no environmental concerns identified. Both the ceramic and wood stave pipe ends were plugged with spray foam. Near the center of the building a single bathtub style drain was identified along with what was suspected to be other sections of water piping and debris from a bathroom covered up during the 11 7 Jewel Building construction (Photo 35, Appendix B). After a thorough inspection, there were no environmental concerns identified in the area. Boiler During a walk around inspection, an opening was identified in the concrete pad at the SE corner of the Jewel building. A floor drain had not been noted in the area however the opening was initially suspected to be a floor drain. After removal of the concrete pad, an old metal boiler, approximately 8 ft x 3ft in size was discovered buried below the pad (Photo 35 to 38, Appendix B). The original location of the boiler is not known. The initial opening identified in the concrete floor occurred where the concrete gave way over a 4” pipe opening in the side of the boiler. A 6” vertical section of 4” pipe that was potentially a plugged floor drain not connected to the building drain system was also identified. No odor or soil staining was identified but a soil sample (21SW-09-SO) was collected to verify the potential floor drain and boiler were not a potential source of contamination. Fuel compounds were detected in the sample however only the compound Naphthalene exceeded the ADEC cleanup level. 1.2. Project Objectives The objective of this project is to remove contaminated media greater than ADEC regulatory cleanup levels from the site so the site may be closed with ADEC, site restoration activities completed, and a new city park constructed. Specific project tasks to achieve this goal were developed based on June 2021 investigation finding and analytical results. Specific project tasks include the following. • Verify/Complete contaminated concrete segregation and removal around the Balto building boiler and AST containment areas. • Segregate the dumpster containerized contaminated floor concrete material from the AST containment stem walls. Dispose of fuel contaminated concrete with the contaminated soil. Collect a new concrete waste characterization sample from the remaining concrete with the objective of disposing of the remaining concrete at the Anchorage Regional Landfill. • Contaminated soil excavation, transportation, and disposal. Removal contaminated soil greater than ADEC regulatory cleanup levels at the Jewel Building boiler area, and the at the Balto Building in the boiler sump, fuel piping and AST containment areas. Due to the presence of Mercury in the Balto building sump area soil waste characterization sample, the soil from this area cannot be thermally treated and must be disposed of out of state in an EPA Subtitle C approved landfill. • Confirmation soil sampling to document excavation clean limits and/or concentrations remaining in accordance with ADEC guidance. • After Action Report. An after-action report detailing all site activities including but not limited to, contaminated media excavation, handling and disposal, waste disposal certificates, sampling activities summary along with analytical laboratory data reports, qualified data results, waste disposal records, site conclusions and recommendations. 12 8 1.3. Regulatory Framework The regulatory framework to guide the execution of this project was developed in consideration of the following regulations and guidance documents: • Field Sampling Guidance, (ADEC 2020) • 18 AAC 75, ADEC Oil and Other Hazardous Substances Pollution Control, (ADEC 2018) • 18 AAC 78 Site Characterization and Assessment (ADEC 2017) • Resource Conservation and Recovery Act (RCRA) in 40 Code of Federal Regulations (CFR) Sampling will be conducted by an ADEC Qualified Environmental Professional, as defined in 18 AAC 75.333 and 18 AAC 78.088. The cleanup criteria for this project will be ADEC’s Method 2 soil cleanup levels as outlined in ADEC regulations 18 AAC 75.340, Tables B1 and B2, Under 40 Inch Zone, Migration to Groundwater. The detection of Mercury in the soil sample identified RCRA waste on this site. In accordance with EPA regulations, a hazardous waste Site identification number (RCRA Site ID) will be obtained for the site through the EPA Region 10. The handling of regulated waste will comply with the RCRA in 40 CFR Parts 260 through 263 and the United States Department of Transportation (DOT) regulations Title 49 CFR Parts 106 through 180. Solid waste will be handled in accordance with 18 AAC 60, 62, and/or 75, as applicable. 13 9 14 10 2. FIELD ACTIVITIES The following sections present the field activities to be conducted to complete the project. 2.1. Contaminated Material Excavation, Treatment, Transport and Disposal The following section outlines the contaminated soil and concrete excavation, packaging, transportation, treatment/disposal methods and requirements. 2.1.1. Contaminated Soil Excavation Soil excavation will be conducted to remove known soil contamination and will be guided based on visual and olfactory evidence in addition to PID field screening results. Soil with visible stains, odor of fuel or headspace field screening test results >20 ppm will be considered fuel contaminated and excavated. Contaminated soil excavation will be conducted at the Jewel Building Boiler and the Balto Building Boiler and AST containment areas. At the Jewel Building boiler, the boiler will be removed, recycled/disposed of offsite and an estimated one to three cubic yards of soil excavated to address the identified soil contamination. At the Balto Building, soil excavation will be conducted within the footprint of the AST containment area, the fuel piping runs and the boiler areas to remove tar, contaminated soil, and any contaminated construction debris (bricks). An estimated 30 to 50 cubic yards of contaminated material is to be removed. Soil excavation will be conducted in a manner that will prevent contaminated soil from becoming mixed with previously uncontaminated soil. The depth to groundwater at the site is anticipated to be near a depth of 200 ft as reported in the closest water well located 1/3 mile to the northwest in the City of Seward Citizens Field Park (DNR WELTS). However, if groundwater or perched water is encountered during soil excavation, a soil sample will be collected from within the first six inches of the water- saturated soil or within the zone of the seasonal water table fluctuation. No dewatering is anticipated during this project. Contaminated soil will be loaded directly into 20 foot open top shipping containers or 1 cy bulk bags for offsite transport and disposal. Contaminated soil excavation will continue until PID results indicate the extents of contamination have been reached or the contract quantities are met. Construction of temporary soil stockpiles is not anticipated however, if temporary soil stockpiles are required to complete the work they will be built, maintained, and sampled in accordance with ADEC guidance. Following completion of contaminated soil excavation activities, excavation confirmation soil samples will be collected. 2.1.2. Concrete Segregation and Removal The June 2021 concrete waste characterization sample results indicate the concrete flooring contains fuel contamination at concentrations greater than the Anchorage Regional Landfill accepted criteria. Fuel contaminated concrete may be comingled with contaminated soil however the concrete must be less than 1 foot in size. Contaminated concrete (floor material and any visibly stained or tar covered material) containerized in the 20 cubic yard dumpster onsite will be broken to size and co-mingled with the contaminated soil for offsite disposal. Concrete with no odor and a minimal tar covering (AST containment wall/footer) will be segregated and a concrete waste characterization sample collected for DRO/RRO and RCRA metals (Total and TCLP). The objective will be to dispose of the remaining concrete material at the Anchorage Reginal Landfill. 15 11 2.1.3. Contaminated Media Treatment, Transportation and Disposal June 2021 soil and concrete analytical waste characterization results were compared to ADEC 18 AAC 75.341 Tables B1 and B2 cleanup criteria and reviewed utilizing Resource Conservation and Recovery Act (RCRA) criteria and a hazardous waste determination made.to determine appropriate handling and disposal in accordance with ADEC and Federal regulations. Due to the detection of Mercury greater than the ADEC cleanup level the soil cannot be thermally treated in Alaska and is classified non-hazardous RCRA waste and will be transported to Columbia Ridge Subtitle D landfill in Arlington, Oregon for disposal. This landfill is a permitted Hazardous Waste Treatment, Storage and Disposal Facility (TSDF) in accordance with Code of Federal Regulations (CFR), Title 49, Chapters 171-180. In general, Bills of Lading and Waste profiles and manifests will be prepared for the shipment of waste and will be completed to meet the following requirements, as applicable: • 49 CFR 172 Subpart B (Table of Hazardous Materials and Provisions) • 49 CFR 172 Subpart C (Shipping Papers) • 49 CFR 172 Subpart G (Emergency Response Information) Contaminated soils transported off-site for disposal shall be covered and fully contained in leak- proof and dust-proof lined vehicles to the degree necessary to prevent discharge or spillage during transport. A Transport, Treatment & Disposal Approval Form for Contaminated Media will be completed and submitted to ADEC for approval prior to transporting contaminated soils from the site. 2.2. Field Screening Field screening will be performed using a photo-ionization detector (PID) during excavation activities to delineate known locations of contaminated soil and to determine excavation confirmation analytical soil sample collection locations. Field screening methods will be conducted accordance with the heated headspace screening method prescribed in ADEC Field Sampling Guidance (FSG). Field screening soil samples will be collected by hand or from the excavator bucket using a disposable stainless-steel spoon. The sampler will collect soil directly into quart-sized Ziploc® bags with double lock seals. The Ziploc® bags will be partially filled with soil and immediately sealed to trap the volatile vapors. The headspace samples will then be warmed to at least 40° F for a period of 10 minutes but not longer than one hour to permit headspace vapors to develop in the bag. The screening samples will be agitated for 15 seconds at the beginning and end of the headspace development to promote volatilization prior to screening with the PID. After sufficient time has passed for the development of vapors, the PID sampling probe will be inserted into the bag to measure the volatile organics. The results will be documented in the field logbook. Contaminated soil excavations will be field screened in accordance with ADEC Table 2B frequencies; 5 field screening samples for the first 50 square feet (sq ft), 5 additional up to 124 sq ft and 1 per 25 sq ft up to 250 sq ft of excavation base with sidewalls field screening 1 per 10 sq ft with screening sample locations from the zone(s) of highest perceived contamination based on visual and olfactory observations in accordance with the ADEC FSG. The project team will 16 12 consider any PID readings >20 ppm as indicative of the potential presence of fuel contamination and continue contaminated soil excavation. Once all field screening results are < 20 ppm then excavation confirmation analytical soil samples will be collected. 2.3. Analytical Sampling Analytical soil sampling will be conducted to characterize waste streams to guide disposal and to provide confirmation results after completion of excavations and to document the presence or absence of any remaining soil contamination at removed site structures. Soil samples will be placed in containers quickly and in the order of volatility; BTEX/VOC, GRO, DRO/RRO, PAHs and metals. For volatile samples the following procedures will be followed: • Collect a minimum of 25 grams of soil with minimum disturbance directly into a tared 4- oz jar with a Teflon®-lined septum lid. Immediately after collection, add one 25-mL aliquot of methanol and then seal the lid on the jar. This step must be completed as quickly as possible to minimize the loss of volatiles. Agitate sample to verify soil is completely submerged in the methanol. • Collect a sample of the same material from the same location in an unpreserved jar for percent moisture determination if the sample is not accompanied by an unpreserved jar for other analytical analysis. • A trip blank sample will be included with the volatile samples for evaluation of the field sample collection quality control. Soil collected for the remaining analyses will be placed into clean laboratory-provided sample jars without preservative. Samples will be placed in a cooler with gel-ice to retain samples between 0°C and 6°C. Field duplicates will be collected at a minimum frequency of 10 percent of primary samples and at least one per day per the ADEC FSG. Soil samples will be delivered to SGS Environmental Services, Inc. (SGS) in Anchorage, Alaska, under standard chain-of-custody procedures. Soil sample analysis will include the following analytes, methods, sample containers and holding times summarized in Table 1. 17 13 Table 1: Soil Sampling Specifications Analysis Method Container* Preservation Hold Time (days) BTEX SW8260D (1) 4oz pre-tared amber glass jar w/TLS MeOH; Store cool at <6°C 14 VOCs SW8260D (1) 4oz pre-tared amber glass jar w/TLS MeOH; Store cool at <6°C 14 GRO AK 101 (1) 4oz pre-tared amber glass jar w/TLS MeOH; Store cool at <6°C 14 DRO AK 102 (1) 4oz amber jar w/TLC Store cool at <6°C 40 RRO AK 103 (1) 4oz amber jar w/TLC Store cool at <6°C 40 PAHs** SW8270D (1) 4oz amber jar w/TLC Store cool at <6°C 40 RCRA metals (Total) SW6020 (1) 4oz amber jar w/TLC Store cool at <6°C 40 RCRA metals (TCLP) SW6020 (1) 4oz amber jar w/TLC Store cool at <6°C 40 * multiple analysis may be combined in the same jar if approved by the laboratory ** collected at 10% frequency TLS – Teflon lined septa TLC – Teflon lined cap MeOH – methanol 2.3.1. Waste Characterization Sampling Previous 2021 analytical results were used to classify the contaminated soil and concrete onsite and generate waste profiles for disposal however, additional soil and concrete waste characterization samples will be collected to further characterize waste for further segregation and disposal guidance. Sample analysis will include DRO/RRO, RCRA metals (total and TCLP). 2.3.2. Excavation Confirmation Sampling Upon reaching contaminated soil excavation extents and PID field screening is complete, analytical confirmation soil samples will be collected from the floor(s) and sidewalls of the excavated areas where PID results were highest following ADEC FSG to confirm contaminated soil removal or to quantify any remaining in-situ soil contamination. Analytical soil samples will be collected per ADEC Table 2B frequencies; 1 for the first 50 sq ft of area, two additional up to 124 square feet 18 14 and 2 for every additional 25 square feet up to 250 square feet. Two samples are required every 100 square feet over 250 square feet of floor area. Soil samples on excavation sidewalls will be collected at one per sidewall plus one additional for areas over 250 sq ft. Soil samples will be collected and handled in accordance with ADEC FSG. At the Jewel Building boiler excavation, sample analysis will follow the ADEC FSG Appendix F analysis for Diesel and Fuel Oils; GRO/BTEX, VOCs, DRO and PAHs. At the Balto Building excavation, soil sample analysis will include FSG Appendix F analysis for Diesel and Fuel Oils (GRO/BTEX, VOCs, DRO/RRO, PAHs) in addition to RCRA metals (Total). 2.3.3. Sample Management The possession and handling of individual samples will be traceable from the time of collection to the time the laboratory reports the results of chemical analysis. The following sections present the sample handling procedures and documentation. A bound and sequentially numbered field logbook will be maintained daily to document all field activities, including the collection of each sample. Field notes, including the logbook, and groundwater data sheets will provide a record of information such as team members, sample locations, field screening results, site observations, and work directives. 2.3.4. Sample Documentation and Numbering When a sample is collected, it will be recorded in the field logbook and at the same time the sample identification number will be placed on the sample container. Samples will be assigned unique identifiers. Samples will be labeled as follows: • YY - Year of sample collection (22) • Location - Ex. SW (i.e. Seward) • Number - Ex. 11 – (to continue from previous numbering) • Type - Ex. SO – groundwater, SO – Soil • Depth - Ex. 05 – 5 feet below ground surface For example, the sample, 22SW-08-SO-05, identifies the 8th soil sample collected from a depth of 5-foot below ground surface. 2.3.5. Sample Custody Procedures will be followed to ensure the custody and integrity of the samples, beginning at the time of sample collection and continuing through the transport, laboratory's receipt, extraction or preparation, analysis, storage, data generation, reporting, and final sample disposal. Once a sample is collected, it will be placed in an iced cooler and will remain in the custody of the field team individual who collected the sample, or the designee, until it is delivered to SGS North America, Inc, in Anchorage, an ADEC approved analytical laboratory. A sample is defined as being under a person's custody if any of the following conditions exist: (1) it is in their possession, (2) it is in their view, after being in their possession, or (3) it is in a designated secure or locked area. 19 15 Chain of custody (COC) records will be maintained for all field and quality control (QC) samples. The following sample information will be documented on the laboratory COC forms: • Sample identification; • Date and time of sample collection; • Sample description (including name, location, and sample type); Preservative used; • Analyses required; • Name of collector(s); • Pertinent field data (high indication of contamination, notable moisture content); • Custody transfer signatures with date and time of hand over between the field personnel, shipper, and laboratory representative. A properly completed COC form for the samples will be placed in a self-sealing-type bag, which will then be taped to the inside lid of the cooler. A separate COC form will be completed for each cooler. Each cooler will be taped closed on the outside with strapping tape and sealed with signed- and-dated custody seals placed on opposite sides and diagonally across the corners of the lid. 2.3.6. Sample Packaging and Shipping The samples will be transferred to the analytical laboratory, SGS in Anchorage, with sufficient time to extract and analyze the sample within the holding time requirements of the analytical method(s). A laboratory representative will receive the coolers ensuring the sample custody integrity and sign a daily chain of custody notebook. Samples will be packaged and shipped according to the following procedures. • Samples will be transported in hard plastic coolers. • Inert absorbent material will be placed in the bottom of the cooler to a depth of two to four inches. • Samples will be properly labeled. • Field personnel will verify that all sample container caps are tight. • The sample coolers will be packaged with sufficient quantities of gel ice to ensure maintained temperature of 4 degrees Celsius (°C) + 2°C. The sample coolers will be stored and shipped in refrigerated containers during transport to the laboratory 2.4. Investigative Derived Waste The investigation-derived waste (IDW) that will be generated during the soil removal effort will consist of disposable sampling materials including used disposable sample gloves, sealable plastic bags, sample scoops and miscellaneous paper waste. IDW will be bagged and taped shut to be disposed at the local municipal landfill. 2.5. Reporting A Removal Action (RA) report will be completed in accordance with ADEC Reporting Guidance for Investigation of Contaminated Sites. The report will provide a thorough understanding of the 20 16 activities conducted at the site and document any deviations to the work scope and the effects of the deviations, if any, to the overall project objectives. The report will also contain tables summarizing the soil sampling results, detailed figures showing sample locations and results, analysis of the data, a completed conceptual site model for the site with graphic estimations of soil and groundwater contamination extents, a description of data gaps, if any, and the potential environmental issues that remain within the study area. If necessary, recommendations for future investigation or follow up remedial actions will be made. Supporting documents in the appendices will include a photograph log, field notes (including excavation details and monitoring well data sheets), laboratory reports with a completed ADEC Laboratory Data Review for each data package and waste certificates of disposal and transport records. 21 Draft Environmental Work Plan 17 3.

(Anchorage) which is an ADEC accepted laboratory. Sample analysis was performed for gasoline range organics (GRO) method AK101/8021 combo (S) field extracted, BTEX prepped by AK101 field extracted, diesel range organics (DRO) method AK102, Residual Range Organics (RRO) AK 103, volatile organic compounds (VOCs) method 8260D (S) field extracted, PAHs method 8270D SIM semi volatiles GC/MS, Metals SW6020B, Metals SW6020B TCLP, PCBs method SW8082 and percent solids by SM21 2540G. All soil data were reported on a dry basis except for metal TCLP analyses in waste sample which was reported in ug/L. The data were reviewed based on a level 2 laboratory report provided by the laboratory and follows the requirements of ADEC Laboratory Checklist (ADEC 2020). A completed checklist of the data can be found in the appendix of the laboratory report. Cleanup levels refer to 18 AAC 75 Oil and Other Hazardous Substances Pollution Control, dated October 2018, Table B1, Method TWO migration to groundwater (MGW) and for the waste sample regulatory limits from 40 CFR §261.24 toxic characteristic were applied. SUMMARY The analytical report was delivered under work order 1213158, Client Project “–CF-Seward”. Ten soil samples were listed on the workorder including one trip blank and one field duplicate. Detection limits (DL), and Limit of Quantitation (LOQs), recoveries and relative percent deviations (RPD) are listed for all analytes as required. Laboratory specific qualifiers were added by the laboratory: “J” (result is an estimate) was applied when positive results were above DL but below LOQ, and “U” (analyte is non-detect) was applied when results were below DL. Quality control (QC) samples such as Laboratory Control Sample (LCS) and Laboratory Control Sample Duplicate (LCSD), and Method Blank (MB) were analyzed at the required frequency to evaluate analytical integrity. One non-project specific Matrix Spike (MS) and Matrix Spike Duplicate (MSD) sample was analyzed by the laboratory to document analytical precision. A case narrative was submitted together with laboratory results. The case narrative indicates QC failures for surrogate recovery in one field extract (21SW- 02-SO), elevated LOQs for PAH analyses in samples 21SW-03-SO and 21SW-10-CO and surrogate 5a- androstane recovery outside QC limits for sample 21SW-10-CO due to dilution. Effects on data usability and qualifier are discussed in the narrative. The analytes benzene, ethylbenzene, naphthalene, o-xylene, p&m- xylene, toluene and total xylenes were analyzed by different methods and sample 21SW-09-SO had positive detects of these analytes. Following ADEC guidelines the highest results should be used for data evaluation and are highlighted in the data tables. High surrogate recovery was detected for DRO in sample 21SW-10-CO due to sample dilution. The results are biased high, but concentrations were 10x above cleanup level and therefore data usability is not affected. Method blank was above ½ LOQ for GRO and DRO no qualifier was applied because analyte concentration in the blank was less than 1/10th of the cleanup level, data usability is not affected. Surrogate recovery for 4-bromofluorobenzene (4-BFB) is below 10% in sample 21SW-02-SO all non-detect VOC analytes were rejected in this sample. Number of rejected results (68) compared to total number of analytes that were measured for the project (888) indicates that workorder is 92% completed. Table 1.

B The analyte was detected in the Method Blank or Trip Blank. R Result is rejected. QH The analyte has a positive result and is biased high. QL The analyte has a non-detect or positive result and is biased low. QN The analyte had RPD outside the QC limits. FIELD SAMPLE REVIEW Sample handling, shipping, and receiving: All samples were listed on the COC and delivered with temperatures below 6 °C. Holding times: All holding times were met for initial extractions and analysis. Sample reporting: All soils were reported on a dry weight basis except for TCLP metals was reported as mg/L. Cleanup level: cleanup levels following 18AAC 75, October 2018 Table B1. Method Two, Migration to Groundwater were used for evaluation of all samples except for TCLP waste sample where regulated limits by 40 CFR § 261.24 - Toxicity characteristic were used. Sensitivity LOQs • VOCs: Analytes 1,2,3-Trichloropropane, 1,2-Dibromoethane and Dibromochloromethane had ½ LOQs above cleanup levels for all samples including the trip blank. Qualifier E was applied to all samples with non-detect indicating that it cannot be evaluated if the analytes exceed cleanup level. • PAHs: Sample 21SW-02-SOhad high LOQs due to sample dilution, this only affected analytes naphthalene. Qualifier E was applied because it cannot be evaluated if sample has concentration above cleanup levels indicating that Surrogates: • VOC: Surrogate 4-BFB was below 10% for sample 21SW-02-SO for VOC analyses. Sample was analyzed twice by the laboratory and low surrogate was confirmed. All non-detect (ND) analytes (68) were rejected (‘R’), indicating that results cannot be used to evaluate contamination in the sample. 171 CF-Seward SDG 1213158 4 • DRO: Surrogate recovery for 5a-androsine was above QC criteria due to matrix interference. Qualifier QH was applied to result indicating that result is an estimate biased high. Data usability is not affected because the result was more than 10x above cleanup level. QC SAMPLE REVIEW Method blanks: • VOCs: All analytes were non-detect (ND). 1,2,3-Trichloropropane and 1,2-Dibromoethane had ½ LOQs above cleanup level. • GRO: Analyte was estimated concentration of 1.33J mg/Kg in the method blank that was associated with all samples. Qualifier was not applied because concentration was less than 1/10th of cleanup level, data usability is not affected. • DRO Analyte was estimated concentration of 7.65J mg/Kg in the method blank that was associated with all samples. Qualifier was not applied because concentration was less than 1/10th of cleanup level, data usability is not affected. Trip Blank: • VOC: positive detects were recorded for benzene, Ethylbenzene, o-xylene, p&m-xylene, and toluene . Qualifier B was applied to all analytes and samples were detected concentration was more than 1/10th of cleanup level of highest sample concentration whichever was greater. This applied to sample 21SW- 09-SO analytes benzene, ethylbenzene, o-xylene, and p&m-xylene, indicating that results may be biased high due to cross contamination. • GRO: positive results were detected in trip blank indicating potential cross contamination. No qualifier was applied because concentration was less than 1/10th of cleanup level, data usability is not affected. • Laboratory Blank (LBl) had concentration above ½ LOQ for Barium TCLP (0.077 mg/L). No qualifier was attached because blank concentration was below 1/10th of cleanup level, data usability is not affected. Equipment blank: No equipment blank was submitted to the laboratory. LCS/LCSD recoveries and RPD: All LCS and LSCD recoveries were within QC limits. MS/MSD recoveries and RPD: MS/MSD was nor required for this project. Sample 1213158004 was used by the laboratory as MS/MSD sample and replaced LCSD for methods 8270D SIM (PAH), SW8260D VOCs and SW8082A PCBs. All analyses were within QC limits. Field Duplicates: Sample 21SW-07-SO and 21SF-08-SO, all duplicates were within QC limits. No duplicate sample was collected for TCLP analyses. METHOD COMPARISON The analytes benzene, ethylbenzene, naphthalene, o-xylene, p&m-xylene, toluene and total xylenes were analyzed by different methods SW8260D VOCs, SW8021B BETX, and SW8270D PAH SIM. Sample 21SW- 09-SO had positive detects of these analytes. Following ADEC guidelines the highest results should be used for data evaluation; these results are highlighted in the data tables. 172 CF-Seward SDG 1213158 5 CONCLUSION There were several QC failures in this workorder which led to application of validation qualifier. Some VOC analytes were reported with ½ LOQ above cleanup levels in samples, method blank and trip blanks and were flagged with E, indicating that it cannot be evaluated if these analytes were above cleanup level. Method blank had concentrations above ½ LOQ for GRO, DRO and barium (TCLP). Data usability was not affected because all blank concentrations were less than 1/10th below cleanup level. Trip blank had positive detects above ½ LOQ for some VOC analytes. Qualifier B was applied to benzene and ethylbenzene for positive detects in sample 21SW-09-SO because blank concentration was above 1/10th of cleanup level and to o-xylene and p&m-xylene because blank concentration was more then 1/10th of detected level in sample. Data usability may not be affected because all sample results were still below cleanup level. Surrogate recovery below 10% in sample 21SW-02-SO lead to reject (R )all non-detected results (68), indicating that these results are not usable to evaluate contamination in this sample.

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 - 1. 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.) If the box is checked, label this pathway complete: Comments: 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.) If both boxes are checked, label this pathway complete: Comments: Can the soil contaminants permeate the skin (see Appendix B in the guidance document)? b) Ingestion - 1. Ingestion of Groundwater Have contaminants been detected or are they expected to be detected in the groundwater, or are contaminants expected to migrate to groundwater in the future? If both boxes are checked, label this pathway complete: Comments: Could the potentially affected groundwater be used as a current or future drinking water source? Please note, only leave the box unchecked if DEC has determined the ground- water is not a currently or reasonably expected future source of drinking water according to 18 AAC 75.350. revised January 2017 2200 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? If both boxes are checked, label this pathway complete: 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). Comments: 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? If all of the boxes are checked, label this pathway complete: Comments: 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.) 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.) If both boxes are checked, label this pathway complete: Are the contaminants in soil volatile (see Appendix D in the guidance document)? Comments: 3 revised January 2017201 2. Inhalation of Indoor Air Are occupied buildings on the site or reasonably expected to be occupied or placed on 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) If both boxes are checked, label this pathway complete: Comments: Are volatile compounds present in soil or groundwater (see Appendix D in the guidance document)? 4 revised January 2017202 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: o 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: 5 revised January 2017203 Inhalation of Fugitive Dust Inhalation of fugitive dust may be a complete pathway if: o 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 - PM10). 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 B1 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: Check the box if further evaluation of this pathway is needed: Comments: Direct Contact with Sediment 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: 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 B1, are assumed to be protective of direct contact with sediment. 6 revised January 2017204 4.

A – The City of Seward (COS) conducted a records search and the additional property ownership details have been added to Section 1.1. 3. 5 1.1, Site Description and Background Is it known what the boilers were used for? As a heat source, power generation, or both? If available, please add more information to the background section. A – The boilers were used for steam generation for heating the buildings and hot water. Additional text has been added to Section 1.1. 4. 5 1.1, Site Description and Background Is it known how and where bunker C was stored at this site? A - Bunker C/fuel oil was stored in the 2,000 gal ASTs. Text in Section 1.1 updated to provide additional detail. 5. 7 AST Containment Is this the same area that the two smaller 400-gallon ASTs were located? If so, please add this information to this section. A – Text updated to provide additional detail. Please also refer to Photo 1 for Balto Building As-built. 6. 1, 7 AST Containment Please confirm the type of fuel oil contained in the ASTs at the time of removal. Coldfoot reported fuel oil was removed from the 2,000 gal ASTs. 7. 6 1.1 Please provide a brief description of the QC failures that are detailed in the analytical report. D – VOC QC failures are detailed in the Data Quality Review. KCI does not feel additional detail on the VOC QC failures is warranted as the soil sample location with the 208 rejected VOC data is to be excavated and removed. 8. 7, 13 1.1 Balto Building, 2.1.1. Were the fuel lines buried underground? ADEC strongly recommends collecting confirmation samples along the entire fuel piping run. The ADEC suggests referring to section 5.5.5 of the 2019 ADEC Field Sampling Guidance for specifications on sampling frequency for buried fuel piping. The fuel lines were located under the concrete lab but not underground. Reference to this section in the FSG was not included in the work plan because the footprint area for all the fuel lines is to be excavated as shown in Figure 3 to address the tar and contaminated soil. Excavations will then be sampled per the FSG per Section 2.3.2 of the Work Plan. 9. 8 1.1.1, Floor Drains Please provide the diameter range for the sentence “A lower ceramic drainpipe 8 to [x] inches in size.” A – The sentence was corrected: “A lower ceramic drainpipe 8 to [10] inches in size.” 10. - General Do the floor drains terminate/connect to city sewer system, leach field, septic tank, Class V injection well? This will need to be investigated. Please describe how you will investigate this and determine if a Class V injection well is present. The EPA regulates injection wells, or underground injection controls (UICs). Derek Schruhl (schruhl.derek@epa.gov) is the EPA Region 10 Class V injection well contact. Discuss with COS & ADEC. Any documentation about the location/status of sewer system? 11. 13 2.1.1 The ADEC Field Sampling Guidance, Section 5, states that the “absence of positive field screening results or those field screening results below an arbitrary threshold cannot be used as justification for not taking the required number of laboratory analytical samples.” Please note that ADEC does not consider non-detect or the <20 ppm field screening results as a justification for not collecting the required number of analytical samples or for determining that an area is not impacted. Intent of comment is unclear, Discuss with ADEC KCI has proposed following ADEC FSG frequencies for soil field screening and sampling. 12. 14 2.1.3 RCRA waste has been identified on this site. Federal regulations apply. This site will need a RCRA site ID. https://www.epa.gov/hwgenerators/getting-hazardous-waste- site-identification-number-region-10#contact The EPA Region 10 Hazardous Waste RCRA notification section can be reached at AlaskaRCRA@epa.gov or 206-553- A – A RCRA site ID will be obtained, and the EPA notified of site activates prior to fieldwork. A paragraph has been added to Section 1.3 Regulatory Framework. 209 1266. 13. 15 2.3 Please note that if groundwater is encountered that ADEC recommends collecting a soil sample from within the first six inches of groundwater-saturated soil or within the zone of the seasonal water table fluctuation. A – Text in Section 2.1.1 was updated to read as follows: “Soil excavation will be conducted in a manner that will prevent contaminated soil from becoming mixed with previously uncontaminated soil. The depth to groundwater at the site is anticipated to be near a depth of 200 ft as reported in the closest water well located 1/3 mile to the northwest in the City of Seward Citizens Field Park (DNR WELTS). However, if groundwater or perched water is encountered during soil excavation, a soil sample will be collected from within the first six inches of the water-saturated soil or within the zone of the seasonal water table fluctuation. No dewatering is anticipated during this project.” 14. 15 2.3.2 TCLP analysis for RCRA metals is not listed as one of the proposed methods. Please note that for disposal purposes, the “Rule of 20” may be applied to determine if the sample is a “toxicity characteristic” hazardous waste. Additionally, RCRA metals analysis results may warrant a resample to include TCLP analysis if initial results exceed ADEC cleanup levels. A - RCRA TCLP analysis is addressed under Section 2.3.1 Waste Characterization sampling. The soil sampling text has been rearranged to provide better clarity. 15. 16 Table 1 Does the bottom row “RCRA metals (Total)” mean to say “RCRA metals (TCLP)”? A – The bottom row will be corrected to “RCRA metals TCLP” 16. - - Please provide photos of the areas of concern in both buildings pre-demolition if available. Please also provide overview photos of the site in its current state (post demolition). A – Pre demolition photos of the areas of concern have added to the Photographic Log however a limited number are available. The photographs in the Draft Photo Log represent current site conditions. 17. Figures 2, 3 Please add labels to both figures depicting the areas of concern such as the “containment area,” boiler room, etc. Please differentiate between the floor drains and sewer lines A - Labels will be added to Figure 2 and 3 to highlight the following: label the boiler room, containment 210 and indicate what sections of piping and drain runs underground versus inside the building. area, underground vs in building lines. Floor drains and sewer lines are the same. 18. 24 Figure 2 What is meant by sewer “outfall”? Do the drain pipes continue from this point? Please add discussion in section 1.1.1 and/or re-label as appropriate. A - The buildings drain lines were only chased and exposed to the edge of the buildings. The Figure 2 label will be changed to indicate the direction of the drain piping at the buildings edge. 19. - General work plan Please provide a site figure that shows the proposed sampling locations relative to the areas of known contamination above ADEC cleanup levels. Discuss w/ ADEC Sampling frequencies will be per the FSG and locations are not known until suspected excavation extents have been reached. 20. 7-9, 23-4 1.1.1-1.1.2, Fig 2-3 Please refer to the enclosed ADEC 2017 Treatment of ND Values, Data Reduction for Multiple Detections, & Comparison of QL’s to CUL’s Tech Memo. As suggested by this memo, “If the LOQ of a ND result exceeds the approved cleanup level, then DEC recommends the LOD be compared to the cleanup level. If the laboratory data does not report a LOD, two times (2x) the DL should be used to estimate the LOD for comparison to the cleanup level. If the LOD exceeds the approved cleanup level, then DEC recommends that an alternative method that would provide lower LOD or LOQ be evaluated.” Please consider the following analytes as COCs: analytes where an estimated concentration can be used or analytes where the LOD can be used in comparison to the ADEC cleanup level. These analytes should be discussed where other COCs are discussed in the report/workplan and labeled on the site figure. These COCs can be removed once adequate sampling suggests that the analytes are not present at the site at concentrations exceeding ADEC cleanup levels. Discuss w/ ADEC. KCI is familiar with the ADEC document however, proposed analysis are in accordance with the FSG App F and none have been omitted. 21. - - Please provide QEP documentation for the upcoming field effort when available. A – Added as Appendix G 22. 47 Analytical Results Table Please add the TCLP screening levels to the results table. A - TCLP screening levels added to the results table. 23.

On behalf of the Seward Mural Society, we have a mural that would fit there perfectly and help explain the historical significance and importance to Seward, the State of Alaska, and the country of the special place. <image002.jpg> The mural “Our Flag flies in Washington”, was designed by Dot Bardarson, painted by the community, and was originally mounted on the old Elk's Club building on 5th Ave. The mural size is 8 x 40 feet, is painted on lightweight aluminum, and could be utilized as a perimeter or wall if needed. A picture is worth a thousand words, as the saying goes, this one showing Benny Benson with the Alaska Flag and the Jesse Lee Home seems like a perfect fit. We would love to see it there, overseeing children playing… Thanks for the consideration!
