Problems/Comments

The site is a fenced, vacant dirt and gravel lot with two attached structures, one building and one former car wash bay. Historically, the site was used as a retail gas station and contained one building, one former car wash bay, four dispenser islands, and underground storage tanks (USTs). On August 20, 1990 one 500-gallon used oil UST, one 400-gallon diesel UST, and one 10,000-gallon gasoline UST were excavated and removed from the site. During removal of the USTs the presence of hydrocarbon impacted soils were observed in the soil. Excavated soil was used to backfill the excavation pits. In 2015 the owner of the adjacent property to the west conducted a Phase II limited investigation of environmental impacts on their property. Elevated concentrations of hydrocarbons, especially benzene, were found in soil and groundwater samples collected throughout the property. Concentrations were highest at the eastern side of the property that borders the site. Preliminary site characterization work was completed at the Five Staur Auto Car Center (Former) site in July of 2019. Eleven soil boring, five monitoring wells, and three temporary well points were advanced to characterize contamination at the site. Gasoline range organics (GRO), diesel range organics (DRO), benzene, toluene, ethylbenzene and xylenes (BTEX), naphthalene, 1,2-dichloroethane (EDC), lead and select volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) were identified above soil cleanup levels at the site. Residual range organics (RRO), GRO, DRO, BTEX, naphthalene, lead, and select VOCs and PAHs were identified in groundwater above cleanup levels.

Action Date	Action	Description	DEC Staff
8/20/1990	Update or Other Action	REM; Alaska Department of Commerce & Economic Development hired Shannon & Wilson to remove 500 gallon waste oil tank, 400 gallon diesel tank, and a 10,000 gallon gasoline tank from the site. 9 soil samples were collected and 7 out of 9 were above DEC cleanup levels. Headspace gas concentrations suggest a volatile source of contamination. Samples at the waste oil tank ranged from 61 - 772 ppm TRPH; diesel tank 601 - 4600 ppm TRPH; gasoline tank had both diesel and gas contamination with diesel in the greatest concentrations: 6 - 6900 ppm and total BTEX ranged from 0.68 - 603 ppm. Samples for halogenated volatiles in the vicinity of the waste oil tank were found to be below detection limits. The water table was encountered at 8.5 - 9 feet below the surface. Excavation halted before PID registered below 100 ppm TPH and the excavated soils were placed back in the holes. A strong hydrocarbon odor was noted at all depths and surface soils were stained to a depth of approximately 1 inch	Former Staff
