Final Report 1992 activities Underground Storage Tank Removals and Site Characterization, Seward, submitted by ENSR. Three USTs: T-3 (500 gal. gas), T-4 (1,000 gal diesel), and T-5( 2,000 gal. gas) were removed 8/10/92-8/11/92. Approximately 170 cubic yards removed and the excavation was backfilled. Contamination was encounted on the east wall of the T3/T4 excavation, but removal of the contaminated soil was limited due to proximity to the railroad tracks. A PVC gallery was installed at the T-3/T-4 excavation. Confirmation soil samples indicate benzene up to 0.19 mg/kg. Contamination was also encountered at the T-5 excavation with benzene up to 0.17 mg/kg. all of the the soil samples for T-3, T-4, & T-5 were taken 6 to 8 feeet bgs. Groundwater was not encountered at any of the former UST excavations. |

Cleanup Complete Determination Issued |
The Alaska Department of Environmental Conservation (ADEC), Contaminated Sites Program, has completed review of the environmental records associated with the ARRC Seward Rail Yard Tanks 3 & 4. Based on the information provided to date, the ADEC has determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment, and no further remedial action will be required as long as the site is in compliance with established institutional controls: 1. Any future change in land use may impact the exposure assumptions cited in this document. If land use and/or ownership changes, current institutional controls may not be protective and ADEC may require additional remediation and/or institutional controls. Therefore, ARRC will report to ADEC every five years to document land use, or as soon as ARRC becomes aware of any change in land ownership and/or use. The report can be sent to the local ADEC office or electronically to DEC.ICUnit@alaska.gov 2.A Notice of Environmental Contamination will be recorded on the ADEC database to document that there is residual contamination remaining on site above the most stringent ADEC cleanup levels. 3.Any proposal to transport soil or groundwater off site requires ADEC approval in accordance with 18 AAC 75.325(i). A “site” [as defined by 18 AAC 75.990 (115)] means an area that is contaminated, including areas contaminated by the migration of hazardous substances from a source area, regardless of property ownership. (See attached site figure.) 4.Movement or use of potentially contaminated soil in a manner that results in a violation of 18 AAC 70 water quality standards is unlawful. 5.The soil contamination located near the railroad tracks at the T3/T4 location is currently inaccessible (see attachment B). When the soil becomes accessible, the soil must be evaluated and contamination addressed in accordance with an ADEC approved work plan. 6. The ADEC recommends that the 2-tier PVC gallery at the T3/T4 excavation be decommissioned.
