8/25/1992 Report or Workplan Review - Other On this date, ADEC received Level I & II Environmental Site Assessment & Geotechnical Recommendations Princess Tours / Westours Leasehold Properties ARRC, submitted by AGRA and dated July 1992. Ten soil borings were advanced on the Princess and West tours lease areas; four of which were completed as MWs. In general, contaminated soil was encountered from 5 to 18 ft. bgs and contained up to 13,000 mg/kg TPH which was located at the GW interface. Groundwater samples collected from the four MWs contained TPH up to 1,200 mg/L. Grant Lidren

4/12/1994 Update or Other Action On this date, ADEC received the Sampling Report for ARRC/Princess Tours & Westours construction project, submitted by ARRC, dated April 12, 1994. Reportedly 1,700 cubic yards of contaminated soil was removed and remediated. The soil sampling for the project was divided into three areas: 12 samples were collected from the Princess Tours area; six samples were collected from the Westours area; and two samples were collected for the Princess Tours Building Foundation. Soil samples collected from the Westours area contained DRO up to 3,170 mg/kg. Soil samples collected from the Princess Tours area and Princess Tours Building Foundation did not contain contaminants above ADEC cleanup levels. Grant Lidren

5/21/2015 Update or Other Action On this date, ADEC received the Environmental Investigation, Modeling and Pipe Recommendations for the ARRC Anchorage Terminal Reserve Waterline Rehabilitation Project, submitted by RSE and dated December 2014. As part of this investigation, borehole TB-8 completed as a temporary MW was advanced adjacent and east of Princess Tours lease. Soil samples collected at 10 feet bgs contained DRO at 261 mg/kg and benzene at 0.036 mg/kg. Soil samples collected at the GW interface at 13.5 feet bgs contained TCE at 0.0799 mg/kg and DRO at 3,370 mg/kg. Groundwater samples collected contained DRO at 5.42 mg/L and RRO at 3.27 mg/L. Grant Lidren
6/27/2018 Update or Other Action On this date, historic contamination was encountered during a PPR response to a diesel spill from a Delta Western Truck at the ARRC yard (spill # 18239919201). The initial spill point was located just behind the Wilderness Express shop adjacent to an above ground HOT. During this spill response, the apparent historic contamination was encountered 1 to 1.5 feet bgs evident by olfactory and visual evidence. Once the assumed Delta Western contamination was cleaned up, the excavation was backfilled due to the fact that it was a high traffic area and a small enough area for it not to be a problem to re excavate the site.
