Underground Storage Tank Site Characterization or Assessment |
Two 2,000 gallon gasoline tanks and their associated piping were removed in October 1999. Up to 0.652 mg/kg benzene and 651 mg/kg GRO left in the excavation. The highest contamination levels were found at the dispenser island at 4 feet below ground surface. Benzene contamination was also found above cleanup levels at the northern tank at 8 feet and 15 feet below ground surface. The south wall of the excavation had high field readings at 4 feet below ground surface, but no analytical samples were collected there. 70 cubic yards of contaminated soil was excavated and stored on the property. The full extent of the contamination has not been defined. Groundwater was not encountered during the tank removal, the deepest portion of the excavation was 15 feet below ground surface. No sampling was conducted for lead or EDB or 1,2-DCA. The tanks were installed in May 1982, due to the age of the tanks they likely to have held leaded gasoline in the past. |

Exposure Tracking Model Ranking |
Site ranked on the new Exposure Tracking Model (ETM). The ETM is a new site ranking system that looks at, based on available data, the potential exposure pathways for the contamination remaining at the site. |

Update or Other Action |
Based on what information that is contained in the DEC contaminated sites files, there has been no additional site work done since the tanks were removed in 1999. The 70 cubic yard stockpile of contaminated soil needs to be assessed for remaining contamination and/or treated in accordance with an approve corrective action plan. The extent of the remaining contamination needs to be defined in the former tank system excavation. This would include the former tank area, the former dispenser, and the south sidewall that had elevated field readings. The analyticals needed would be BTEX, GRO, lead, EDB, 1,2-DCA, and naphthalene. |

Update or Other Action |
To date have not received documentation or work plans for further site work. Need the 70 cubic yard stockpile of contaminated soil be assessed for remaining contamination and/or treated in accordance with an approve corrective action plan, and request that the extent of the remaining contamination needs to be defined in the former tank system excavation. This would include the former tank area, the former dispenser, and the south sidewall that had elevated field readings. The analyticals needed would be BTEX, GRO, lead, EDB, 1,2-DCA, and naphthalene. |
