Problems/Comments

The Kodiak Council on Alcoholism contaminated site property was formerly occupied by an outpatient addiction treatment program and was recently transferred to the Native Village of Afognak. The site is located in Section 32, Township 27 South, Range 20 West, and the Seward Meridian. A Phase I Environmental Site Assessment (ESA), of the property was completed in September 2006 and reported that a heating fuel Underground Storage Tank (UST) was decommissioned at the subject site in 2005. The UST formerly supplied heating oil to the onsite structure and was reportedly closed in-place near the northeast east wall of the structure. No records or documentation exist for the initial in-place closure. On December 7, 2006, a Limited Phase II ESA was performed to determine if a petroleum release had occurred prior to the in-place closure. During investigations, the top of the UST was discovered at roughly three feet below ground surface (bgs). Results of the Phase II revealed that petroleum contamination, primarily Diesel Range Organics (DRO) was present in the sub-surface soils at levels ranging between 3,780 mg/kg to 7,540 mg/kg, which exceeded the DRO, ADEC Migration to Groundwater (MTG) cleanup level of 230 mg/kg. In September 2006 a Phase I ESA was conducted and submitted to KeyBank. It was found that a former heating oil UST was removed, and the closure and removal procedure did not produce a closure data report. December 7, 2006 a Phase II ESA was conducted, and an excavation was performed to determine if a petroleum release had occurred prior to the in-place closure. This revealed that a 1,000-gallon heating fuel UST was closed in place in 2005. It was reported that soil samples had been collected, but no analytical data could be found. It was determined that the site was excavated only enough to decommission the tank, so soil samples may not have been collected. During the excavation, the top of the UST was discovered at roughly three feet bgs. The excavation continued to the north, east, and south until the base of the UST was uncovered, which was at roughly eight feet bgs. Holes and pitting were noted in the bottom of the former UST. During the investigation, groundwater was encountered at various depths, primarily between six and 7.5 feet bgs. Prior to backfilling with the excavated material, three soil samples were collected from the base of the excavation and were analyzed for DRO, GRO, RRO, and BTEX. Results of the 2006 Phase II revealed that petroleum contamination, primarily DRO, was present in the sub-surface soils at levels ranging between 3,780 mg/kg to 7,540 mg/kg, which exceed the ADEC migration to groundwater cleanup level for DRO of 230 mg/kg. Perched water was encountered between six to 7.5 feet bgs. The highest contaminant levels were located at about eight feet bgs, the level of the bottom of the UST. In May 2019 site characterization activities were conducted and generally consisted of a UST removal, test pit excavations, groundwater monitoring well installation, and sampling of groundwater and soil. All soils samples were analyzed for DRO and GRO. Most soils samples were analyzed for BTEX. A handful of samples were analyzed for PAHs and VOCs. The handful of samples included are TP1-49, TP1-X, UST-127, UST-136, SP-3, UST-2X, UST, UST-X, TP2, and TP3. Soil samples UST-143 and TP3-67 exceeded Migration to Groundwater for DRO. Soil samples USTX and UST127 exceeded Migration to Groundwater for DRO and a few other PAHs and VOCs. Sample UST2X exceeded Migration to Groundwater for various PAHs and VOCs. Groundwater sample USTX exceeded for DRO at 6.94 µg/L, Naphthalene at 23.8 µg/L, 1-and Methylnaphthalene at 11.9 µg/L. All groundwater samples were analyzed for DRO, GRO, PAHs, and VOCs. Groundwater sample UST exceeded for DRO at 7.16 µg/L, Naphthalene at 24 µg/L, and 1-Methylnaphthalene at 15.1 µg/L. Groundwater sample TP3 exceeded for DRO at 1.71 µg/L. In August 2020 site characterization activities were conducted and generally consisted of test pit excavation and soil sampling. TP4A, TP4B, and TP5 were excavated and sampled. All soils samples were analyzed for DRO, GRO, PAHs, and VOCs. Soil samples RSE-9(TP4A), RSE-15(TP4B), RSE16 (TP4B), and RSE-22(TP5) exceeded Migration to Groundwater for various PAHs and VOCs. RSE-XX(TP4B) exceeded Human Health cleanup levels for 1,2-Dibromoethane and MTG cleanup levels for various PAHs and VOCs.

Action Information

Action Date Action Description DEC Staff
10/25/2006 Document, Report, or Work plan Review - other Phase I ESA conducted by URS submitted to KeyBank. The lack of documentation regarding the removal of the former heating oil UST constitutes an onsite recognized environmental conditon. No additional onsite activities or conditions known to have created a recognized environmental condition on the subject property were identified. No off-site facities were known to have created a recognize environmental condition on the subject property were identified. It was recommended that if the UST closure data cannot be located, that further site investigation is warranted to determine current site conditions, and if remedial actions are required. Donald Seagren
1/8/2007 Document, Report, or Work plan Review - other URS submitted limited Phase II ESA to Key Bank. A 1000-gallon heating fuel UST was closed in place in 2005. It was reported that soil samples had been collected, but no analytical data could be found. It was determined that the site was excavated only enough to decommission the tank, so soil samples may not have been collected. The excavation was limited due to foundations, utility lines, and other infrastructure. Perched water was encountered between 6 - 7.5' bgs. The highest contaminant levels were located at about 8' bgs, the level of the bottom of the UST. DRO concentrations (3,780 mg/kg - 7,540 mg/kg) are present in the soil at concentrations exceeding ADEC soil cleanup levels. Due to the proximity of the building foundation and other infrastructure, excavation of the contamianted soil may not be possible. Donald Seagren

10/27/2014 Potentially Responsible Party/State Interest Letter Completed a site evaluation and letter to the RP on this day. Site history: In 2005, in preparation for a property transfer or sale, a phase I environmental site assessment (ESA) was performed to evaluate the environmental condition of the property. Results of the ESA indicated that a 1,000-gallon underground storage tank (UST) was decommissioned in 2005. The UST formerly supplied heating oil to the onsite structure and was reportedly closed in-place near the northeast east wall. No records or documentation exist for the initial in-place closure. On December 7, 2006, an excavation was performed to determine if a petroleum release had occurred prior to the in-place closure. During the excavation, the top of the UST was discovered at roughly three feet below ground surface (bgs). Excavation continued to the north, east, and south until the base of the UST was uncovered, which was at roughly eight feet bgs. Holes and pitting were noted in the bottom of the former UST. During the investigation, groundwater was encountered at various depths, primarily between 6 and 7.5 feet bgs. Prior to backfilling with the excavated material, three soil samples were collected from the base of the excavation, and were analyzed for gasoline range organics (GRO), diesel range organics (DRO), and benzene, toluene, ethylbenzene, and xylenes (BTEX). Results of the 2006 investigation revealed that petroleum contamination, primarily DRO was present in the sub-surface soils at levels ranging between 3,780 mg/kg and 7,540 mg/kg. The ADEC cleanup level for DRO is 250 mg/kg. As of this date, extent of soil and groundwater contamination remains undefined. Joshua Barsis

Jessica Hall
1/27/2021 Update or Other Action Received a phone call from Afognak asking about sampling results from site work in Fall 2020. Awaiting site characterization report from RSE to provide that information. Jessica Hall
3/11/2021 Document, Report, or Work plan Review - other Sent RP ADEC comments for Kodiak Council on Alcoholism 2020 Additional Site Assessment, dated February 8, 2021. Requested updated report be submitted by April 15, 2021. Jessica Hall
4/1/2021 Site Characterization Report Approved Sent RP Approval of Kodiak Council on Alcoholism 2020 Additional Site Assessment, revised March 26, 2021. RP requested for Site closure - ADEC is unable to concur with the report recommendation to issue site closure currently. The following data gaps exist that prevent site closure: 1.)DRO, naphthalene, 1- methylnaphthalene, 2- methylnaphthalene, and 1,2,4 Trimethylbenzene have not been characterized to migration to groundwater cleanup levels for soils to the north of the site. 2.)DRO is not characterized to migration to groundwater cleanup levels for soils southeast of the site. 3.)DRO has not been characterized to migration to groundwater cleanup levels for soils west of the site. 4.)The migration to groundwater and groundwater acting as a transport pathway atop bedrock remains open as the data is inconclusive. Groundwater samples did have contamination in 2019, and groundwater was either not encountered or had detections in 2020. Jessica Hall
