We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.

Problems/Comments

Return line failure caused release of fuel to the subsurface including the utility corridors exiting the building. Underground storage tank (UST) closure by removal allowed free product recovery. Indoor air quality was assessed and groundwater monitoring wells were installed and sampled for one year. Contaminated material was stored off-site. Soil and groundwater analyticals indicate diesel contamination is present above applicable cleanup screening levels.
