Problems/Comments
The subject property began operation as a convenience grocery and liquor store in 1982, and added a gasoline station in 1996 with the installation of one 15,000-gallon gasoline underground storage tank (UST) (DEC tank ID 1 / Owner Tank ID 1&2). The property continued to operate as a gas station and store until it closed sometime prior to May 2014. A 161' deep open end drinking water well was installed on the property in 1982. The drinking water well and the on-property building are currently not in-use but are planned to be used in the future. In May 2014, a Phase II Environmental Site Assessment (ESA) was performed to assess the subsurface conditions at areas of concern near the UST and several surface stains behind the building. A total of six borings were advanced on the property; five surrounding the UST and dispensers, and behind the store building at one of the several surface stained soil locations. The depth of soil borings ranged between 5 feet to 20 feet below ground surface (bgs). One or two soil samples from each boring were submitted for laboratory analytical testing. The soil samples were analyzed for BTEX, MTBE, GRO, and DRO. Soil boring SB1, located on the west side of the UST, contained a total xylenes concentration of 6.1 milligrams per kilogram (mg/kg) (above its applicable ADEC cleanup level of 1.5 mg/kg) at the sample collected between 0.5 to 1.5 feet bgs. That sample also had detectable GRO, toluene, and ethylbenzene that were below cleanup levels. At the request of ADEC UST Program staff, a tightness test was performed on the tank and its piping in 2017. The system failed the initial line-tightness testing. After the broken shear value was replaced and the fittings were tightened the system passed the tightness testing. On January 19, 2018 two soil borings were sampled near (within 5 feet of the tank to the northeast and southwest) the underground storage tank and dispensers which are located above the tank. Two soil samples were collected from each boring, one within 2' below the bottom of the tank and the other at the highest field reading depth in that boring. All of the samples were analyzed for full VOCs, GRO, and PAHs and all of the samples were non-detect for all compounds analyzed.

| 1/12/2018 | Document, Report, or Work plan Review - other | Call from Adam Turner, they were doing the utility locates and their is a conflict with the proposed northeast boring location. They plan to move it to the southeast of the tank near the tank and dispenser. He also mentioned that they would need to move the southwest boring location about 3 feet to the west. He will send en email regarding this. | Robert Weimer |

Two soil samples were collected from each boring, one within 2' below the bottom of the tank and the other at the highest field reading depth in that boring.
