Problems/Comments

In 1997, a 30,000-gallon diesel fuel UST and associated lines and dispensers was removed and decommissioned along with approximately 300 CY of contaminated soil. Remedial activities conducted by AGRA Earth & Environmental (AGRA) in 1998 removed an additional 650 CY of contaminated soil. AGRA indicated a small amount of petroleum impacted soil remained near a concrete pad of the former fuel dispenser island. ICE Alaska purchased the property in 2011, without apparent knowledge of contamination issues. Former owner & RP agreed to address remaining contamination concerns - mainly petroleum in soil and groundwater near the former dispensers.

9/30/2008 Document, Report, or Work plan Review - other Received and reviewed the Rockwell Engineering Groundwater Investigation report for H&H Contractors. DRO (2.84ppm) and benzene (9ppb) are above DEC cleanup levels on the well located in the source area. Two additional temporary wells were installed near the location of the Trailers. All contaminants in these two wells were non-detect. No workplan was submitted for this work. The downgradient well at Constructions Parts was not sampled. DEC requested a CSM and sampling of the Construction Parts well. Tamara Cardona-Marek

7/25/2013 Update or Other Action Received assessment report and work plan for Ice Alaska property/former excavation & dispenser island. Jim Fish
7/29/2013 Cleanup Plan Approved Cleanup Plan (proposed excavation and land farming) approved. Groundwater monitoring will also be conducted after new monitoring well installations. Jim Fish
7/16/2014 Update or Other Action Consultant indicated report of excavation, moniotring well installations, and land farm construction pending. Jim Fish
9/18/2014 Document, Report, or Work plan Review - other Site characterization report received today. Jim Fish
6/17/2015 Update or Other Action Received a September 2014 Bio-Cell Field Screening Results Report and an October 2014 Groundwater Monitoring Report from consultant (Nortech) Jim Fish
7/6/2015 Update or Other Action Received a soil boring report for 2014 activities to characterize remaining soil contamination and groundwater elevations. Jim Fish
1/8/2021 Meeting or Teleconference Held DEC staff teleconference with consultant, discussed current site conditions and additional site activities. Landfarming management was the primary focus of the discussion, as the landfarm had not been tilled for some time and it no longer had a functioning cover. Frequent tilling over the entire depth was recommended. PID headspace sampling was conducted last year. Only a small area of soil near the bottom of the 18" layer had elevated headspace readings (500 to 700 ppm). The consultant will work with the RP to plan multiple tilling events this next summer and contact the DEC with the proposed plan. The consultant also reported that no additional groundwater monitoring had been conducted since the last report in 2014. Shawn Tisdell
9/15/2022 Site Characterization Workplan Approved Work plan for soil sampling the landfarm originally received 8/4/2022 was approved following revision updates. This plan presents a multi-incremental sampling strategy to provide data to determine if prior fertilizing and tiling activities have sufficiently remediated the soil and allow for closure of the landfarm. Shawn Tisdell
3/20/2023 Site Characterization Report Approved The revised Former Underground Storage Tank landspread Stockpile Sample Results Report submitted by Nortech on March 7, 2023 has been reviewed and approved. This report indicated incremental sampling of the landfarm and discrete sampling of the surface soil beneath the landfarm liner was conducted during September and November of 2022. Sample results indicate that the landfarm soil and the soil immediately beneath the landfarm were all below the DEC cleanup criteria for unrestricted use. The DEC requested a work plan be prepared that identifies a strategy to characterize data gaps remaining at the site. Shawn Tisdell
10/4/2023 Site Characterization Workplan Approved Work plan objectives include current evaluation of the groundwater contamination and contaminant trends, complete a relative elevation survey and determine the groundwater gradient, and collect water quality and geochemistry parameters, which include dissolved oxygen, nitrate, ferrous iron, sulfate, methane, oxidation-reduction potential, pH, temperature and conductivity. Seven wells will be sampled in October 2023 and results will be provided in a report within 6 weeks of the completion of the fieldwork. Shawn Tisdell
