Problems/Comments
The Valley Country Store I (Facility ID 1988) currently operates as a fueling station and convenience store. Between 1983 and 1984, two 10,000-gallon unleaded gasoline underground storage tanks (USTs) and a 5,000-gallon diesel UST and associated dispensers were installed at this site (Tanks 1, 2, and 3, respectively). In 1994, Tanks 1 through 3 were removed and replaced with a single 18,000-gallon UST (Tank 4) that contained gasoline and diesel in separate compartments. In November of 2013, the piping and dispensing equipment associated with Tank 4 were removed and upgraded with new equipment. During the removal, contaminated soil was encountered (diesel range organics up to 563 mg/kg). The previous removal of tanks 1 through 3 are documented under ADEC file number 2265.26.012; Hazard ID 23524.

| 4/14/2014 | Document, Report, or Work plan Review - other | The ADEC received a Release Investigation/Closure Report, dated February 12, 2014 that documented the replacement of six fuel dispensers and piping associated with Tank 4. The dispensers and their piping were excavated from the ground on November 26 and December 4, 2013. During the excavation, soils were field screened with a photoionization detector (PID) and stockpiled accordingly. Confirmation soil samples were collected from the excavation and one of the samples exhibited a concentration of DRO at 563 milligrams per kilogram (mg/kg), which is above the ADEC cleanup criterion for DRO (250 mg/kg). On December 9, 2013, an additional excavation was commenced to remove the previously mentioned DRO contamination. Analysis of the samples collected from this event did not exhibit any contaminant concentrations above the ADEC cleanup levels. The contaminated soil stockpile remains onsite. This site is recommended for closure once the onsite soil stockpile is remediated or treated offsite. The RP indicated that the soil stockpile will be disposed of at ASR summer of 2014. | Joshua Barsis |
