New York City E Designated Site and NYSDEC Spill Site

Hydro Tech Environmental, Corp. has supervised and documented the environmental closure activities for a property in Queens, New York. The property was associated with a New York State Department of Environmental Conservation (NYSDEC) Spill number and was also associated with an “E”-designation. Hydro Tech performed the remedial activities under the guidance of both the New York City Department of Environmental Protection (NYCDEP)/NYC Office of Environmental Remediation (OER) and the NYSDEC.

The remedial activities at the property commenced in May 1999. A NYSDEC Spill number was issued to the property after contaminated soil was identified during the excavation and removal of thirteen (13) 550-gallon underground storage tanks (USTs) by others. Over 100 tons of contaminated soil was removed from the property. However, in April 2007, Hydro Tech performed a Phase I ESA and discovered that the NYSDEC Spill number issued in 1999 had not been closed. In addition, Hydro Tech determined that an “E”-designation was associated with the property. Subsequently, Hydro Tech performed a Subsurface Investigation and identified residual contaminated soil in the vicinity of the historical USTs. An addition 150 tons of contaminated soil was removed from the property, endpoint samples were obtained in accordance with draft DER-10, and the results indicated that all contaminated soil had been properly excavated. Based upon these results Hydro Tech petitioned the NYSDEC to close the case, and their Spill number was subsequently closed in October 2008.

Hydro Tech then supervised the remaining construction activities and filed a closure report with the OER. In August 2009, OER issued the Notice of Satisfaction to the now completed 4-story commercial building
