We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


A 1996 phase II site assessment found the site to be an oil refinery operation, which was destroyed during the 1964 earthquake. The site was also later used from 1977-1988 as a barrel reconditioning operation. Visual signs of the site uses included machinery, drums, spills, a Process underground storage tank (UST), and a gasoline UST. The two USTs, which were found to be the main source of contamination, were removed from the site in 1995 and 1996. 1996 soil boring samples and monitoring wells indicated high diesel range organics (DRO) levels. An 1997 investigation found free phase arctic-grade diesel in the groundwater which is speculated from an upgradient, northeast, offsite source. A 2000 field sampling report found high levels of DRO as well as chorinated solvents. A 2003 groundwater assesment report found DRO and benzene, toluene, ethylbenzene, and xylenes (BTEX) levels decreasing due to natural attenuation, but a few select wells still had high levels of DRO, gasoline range organics (GRO), and benzene. Futhermore, well CHMW2 had 2.2 feet of free-phase product with the the thickness of the free-phase product in the formation of 0.55 foot. A 2007 ATR FS remedial investigations for Groundwater Area 5 (GW-5) indicate that while trichloroethylene (TCE), benzene, and DRO contamination exist, the plume appears stable and is not migrating toward Ship Creek. Visibly contaminated soil with waste oil in suspected 100 feet by 100 feet area. Alaska Railroad/U.S. Department of Transportation (DOT), ARR contract 4716, lot 87 off Whitney Road, leased property from 1958 to 1988 to Arctic Cooperage who used as waste oil refinery and reportedly accepted transformers from local electric utility companies that may have contained polychlorinated biphenyls (PCBs). Administrative order on consent (U.S. Environmental Protection Agency (EPA) Docket No. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) 10-2004-0065) signed to include ARRC terminal, Area 3, and designated leased properties.

Action Information

Action Date Action Description DEC Staff
8/24/1988 Preliminary Assessment Approved Arctic Cooperage/Arctic Rerefining report, September 6, 1988, Alaska Railroad Corporation. Site visit and interview with former employee at site indicated large but unknown quantities of waste oil, sludge and possibly PCBs were accepted and dumped on site in approximately 100' x 100' area. Some areas are visibly contaminated with waste oils and other areas have been filled in. Paint spills and 55 gallon drums also visible. Site located about 200' north of Ship Creek. No Longer Assigned
4/24/1990 Site Ranked Using the AHRM Initial ranking. No Longer Assigned
1/1/1992 Site Added to Database Petroleum and metals contamination. No Longer Assigned
9/25/1996 Site Ranked Using the AHRM Site reranked. Toxicity Value changed from 1 to 3; and multiple sources changed from "n" to "y". Scott Pexton
10/2/1996 Site Characterization Report Approved (Old R:Base Action Code = SI - Site Investigation). Phase II Site Assessment prepared by ENSR Corporation was received. This report was also submitted to EPA for evaluation and ranking to evaluate for inclusion on the NPL. In soil, GRO ranged from 10 to 1,430 mg/kg, DRO ranged from 10 to 8,450 mg/kg, copper detected at 746 mg/kg, lead detected at 1,690 mg/kg, PCE detected at 0.6 mg/kg, and acetone reported at 3 mg/kg. Scott Pexton
10/17/1996 Update or Other Action Letter sent to ARRC regarding review of Phase II Site Assessment; request for written responses to comments. Scott Pexton
10/24/1996 Update or Other Action Letter received from ARRC requesting approval for thermal treatment of soil stockpile at Arctic Cooperage. Lead levels from ten samples range from 100 mg/kg to 360 mg/kg; DRO reported at 8,400 mg/kg and GRO at 3,300 mg/kg from composite sample. Metals did not fail TCLP. Soil not planned for removal/treatment until after spring breakup, 1997. Scott Pexton
11/13/1996 Update or Other Action Letter received from ARRC responding to comments from ADEC regarding Phase II Site Assessment. Scott Pexton
2/14/1997 Update or Other Action Copy of letter to ARR from EPA's Site Assessment Manager regarding the Phase II Site Assessment Report. EPA determined that the facility does not score high enough to be proposed for inclusion on the NPL and recommends NFRAP on EPA's part. Scott Pexton
6/30/1997 Site Characterization Workplan Approved The work plan is a continuation of previous site investigations and is described as Phase 3. Jim Frechione
8/1/1997 Update or Other Action Field work to install soil borings and monitoring wells is initiated. Free phase product is detected in several wells. Jim Frechione
3/10/1998 Update or Other Action ARRC submits Report of Findings associated with the August investigation. The report concluded that free product was present partly due to past site operations but also from other upgradient sources. The ARRC proposes to continue product recovery and monitoring. They also will continue to investigate other possible sources. Jim Frechione
2/12/1999 Update or Other Action CSRP and STP jointly send letter to ARRC requesting enhanced free product recovery and cleanup action plan. Jim Frechione
4/30/1999 Update or Other Action ARRC submits Whitney Road Product Plume Investigation Work Plan for ADEC approval. Jim Frechione
12/29/2000 Update or Other Action 2000 Field Sampling summary report submitted. Renee Evans
6/12/2001 Update or Other Action Soil stockpile results submitted and request to transport soils for thermal treatment. Renee Evans
12/11/2002 Update or Other Action Meeting with ARRC. The need for GW monitoring was discussed and iIt was agreed that consultant (Susan Shrader) will submit sampling work plan and provide update as to status of stockpile. Linda Nuechterlein
2/3/2003 Update or Other Action Samping Plan for GW monitoring received. Bob Glascot will serve as PM and review this during interim while LN is filling in for Dave Allen. Linda Nuechterlein
10/22/2003 Update or Other Action ADEC receives notice from Alaska Railroad that Soil Recycling treated 48.42 tons of soil from Arctic Cooperage site. Jim Frechione

6/21/2007 Update or Other Action Remedial Investigation Alaska Railroad corporation Anchorage Terminal Reserve U.S. EPA Docket No. CERCLA 10-2004-0065, submitted by ENSR. Groundwater Area 5 (GW-5) investigation encompasses the former Arctic Cooperage lease. Additional groundwater data collected for the RI investigation include benzene up to 0.021 mg/L, TCE up to 0.0051mg/L and DRO up to 10.3 mg/L detected in center of the lease property. Downgradient wells indicate contaminants are not migrating toward Ship Creek and the plume appears to be stable.
