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

Initial complaint and problems: Soil and groundwater contamination found on property. ADEC has received complaints regarding potential contamination on the property and concerns about possible contamination of nearby drinking water wells. Contamination is suspected to be from vehicles operated and stored on the property and from four 1000-gallon regulated underground storage tanks (UST's). Three of the USTs were closed-in-place at the site and a fourth was removed. The USTs that were closed in place were two gasoline tanks and a diesel tank. A waste oil tank was removed. The file also includes reports that Diversified Storage personnel pressure washed and steam cleaned construction trucks and oily equipment on site, increasing the contamination. Former file number: 2100.26.248.

Requirements

Description Details
Other There is a water well on the site that intercepts a deep aquifer (>60 feet). The well water is reportedly not used for drinking for secondary water quality reasons. It has been tested and is not contaminated. It is believed to be completely isolated from the upper aquifers. Shallow groundwater in two upper aquifers may not be used, if use or dewatering is proposed, Dept. notification and approval is required.
Advance approval required to transport soil or groundwater off-site. Standard condition.
Movement or use of contaminated material (including on site) in a manner that results in a violation of the water quality standards is prohibited (18 AAC 70) Standard condition.
