Problems/Comments

Soil contamination was encountered during the removal of a 500-gallon home heating oil underground storage tank (UST) in July 1999. Following tank removal the excavation was lined with plastic to a depth of six feet below ground surface(bgs) and backfilled with clean fill. Additional work was done in fall 2000 after the property was conveyed to the Dept. of Veteran's Affairs (VA) through foreclosure. The VA's contractor excavated and disposed of 28 tons of contaminated soil from the subsurface interval of 6 to 14 feet and installed a monitoring well within the excavation in groundwater encountered at 12 ft bgs. Excavation was halted near the building foundation to avoid compromising the structure of the house and an unknown quantity of contaminated soil remained. Monitoring well results for the single sampling event within yielded detectable levels of diesel range organics (DRO), xylene and toluene with all results below 18 AAC 75.345 Table C cleanup levels. Site evaluation and cleanup were completed in 2016 following installation of three borings installed as monitoring wells; no soil or groundwater samples contained contaminants exceeding applicable cleanup levels. Groundwater flow direction is to the west. Site closure requirements were completed upon decommissioning of the three monitoring wells on May 5, 2017.

Action Information

Action Date Action Description DEC Staff
11/8/1999 Update or Other Action On 11/08/1999 ADEC received a faxed spill report and field notes prepared by consultant Tellus, Ltd. received and forwarded by a realtor on that date, stating that contamination was encountered during removal of the underground heating oil tank at the site. The field notes state that overburden soil appeared clean, but when the UST was removed soil staining beneath the tank bed, discoloration and strong fuel odor were observed. Tellus observed fuel staining on the tank with a hole in the bottom of the tank beneath the fill pipe end. No sidewall staining was observed. Also included in the fax is a VA sales listing dated November 5, 1999 that lists the property for sale as-is. Former Staff
12/3/1999 Potentially Responsible Party/State Interest Letter ADEC letter dated 12/3/1999 advises the Department of Veteran's Affairs (VA) that it is financially liable for contamination at the site and requests submittal of a cleanup plan by January 5, 2000. (Note that ADEC later determined - in September 2000 - that the VA was not a liable party based on the lender "safe harbor" exemption of AS 46.03.826(8)). Former Staff
12/7/1999 Update or Other Action VA letter dated 12/7/1999 to realtor (VA Management Broker) asking that realtor comply with ADEC requirements in an attached letter from ADEC dated 12/3/1999, with the note that VA legal counsel is continuing to research this area since VA did not become an owner until September 13, 1999 as a result of a conveyance from the mortgage holder, Midfirst Bank, subsequent to their foreclosure action on August 19, 1999. Former Staff
12/28/1999 Update or Other Action ADEC received a letter from the VA dated 12/28/1999 advising ADEC that it was seeking three bids for an initial site assessment and would also be removing the carport to better access the site. The letter requests an extension of ADEC's January 5, 2000 deadline to March 5, 2000. Former Staff
2/8/2000 Document, Report, or Work plan Review - other ADEC letter dated 2/8/2000 approves the extension for plan submittal requested in the VA's letter dated 12/28/2000. Former Staff
2/9/2000 Update or Other Action VA attorney letter to ADEC dated 2/9/2000 stating the VA's position that they are not liable for spill cleanup based on VA's status as a guarantor and the statutory lender liability exemption and requesting the State of Alaska's position on this issue. Former Staff
2/18/2000 Potentially Responsible Party/State Interest Letter ADEC's letter to former property owner Raymond Arrington dated 2/18/2000 by spill response staff notified Mr. Arrington of his liability for the release and of ADEC's cost recovery requirements, and requested a cleanup plan by March 5, 2000. Mr. Arrington's home was foreclosed on August 19, 1999 and his current address is in North Carolina.(No response was received). Former Staff
3/24/2000 Document, Report, or Work plan Review - other In a letter dated 3/24/2000, spill response staff Frank Wesser approved the "Site Characterization Plan for 161 Jelinek" prepared by Environmental Management Inc. (EMI) and submitted by fax on 4/10/2000. Former Staff
4/10/2000 Update or Other Action EMI submitted a work plan dated 4/10/2000 on behalf of the VA to drill 4 boreholes with one boring to be completed as a monitoring well in the area of suspected contamination (if ground water is encountered above 30 ft below ground surface). The plan proposes to collect two laboratory samples from the soil borings around the UST to be analyzed for Diesel Range Organics (DRO), Residual Range Organics (RRO), and Benzene, Toluene, Ethylbenzene, and Xylene (BTEX) from areas where the highest field screening results were obtained. An additional sample will be collected from the hole that will be drilled for the monitoring well at the depth where the contamination appears to stop. One water sample will be collected from the monitoring well and analyzed by the same analyses as above. Former Staff
4/24/2000 Document, Report, or Work plan Review - other ADEC approved the site characterization plan received on 4/10/2000 in a letter dated 4/24/2000. Eileen Olson
10/3/2000 Update or Other Action ADEC spill response received the "Interim Site Characterization Report" dated October 2000 that reports work done in May and June 2000 in accordance with the approved work plan dated April 10, 2000. The laboratory results from the bottom of the boreholes indicated there was diesel range organic (DRO) contamination present greater than anticipated ADEC cleanup levels beneath the old tank, l0-11 feet below ground surface (bgs). The equipment used in the investigation could not penetrate the soils deeper than II feet bgs due to large cobbles and gravel. DRO was present at concentrations of 2,789 mg/kg a 10 ft bgs and 799 mg/kg at 11 ft bgs. Groundwater was not encountered by the maximum depth of 11 ft bgs. Former Staff
10/4/2000 Update or Other Action ADEC received a site cleanup plan dated 10/4/2000 that proposes completing interim cleanup action at the former UST site at the same time it finishes site characterization. Contaminated soil that was identified in May 2000, present at about 7 ft below ground surface or below the visqueen barrier, will be removed to the extent possible. If groundwater is not encountered and the laboratory samples from the bottom and sidewalls of the excavation are below the cleanup levels determined for the site by ADEC, a monitoring well will not be installed. Former Staff
11/7/2000 Update or Other Action ADEC received November 2000 "Site Characterization and Interim Cleanup Report." Former Staff
