Union Turnpike

Queens, NY
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.



Clarendon Road

Queens, NY
NYSDEC Spill Site. Excavation of Contaminated Soil and Underground Storage Tanks, Remediation of Groundwater and Vapor Assessment.

Hydro Tech performed the removal of underground storage tanks (USTs), and soil and groundwater remediation during the re-development of a former gasoline station into a commercial strip mall. The remediation was successfully coordinated with the New York State Department of Environmental Conservation (NYSDEC) and two NYSDEC spill numbers were closed. The remediation was beneficial to the site development in that the UST and contaminated-soil excavations were generally limited to basement foundations, and groundwater was treated through monitoring and natural attenuation. In other words the remediation did not impact upon the development of the property.

Hydro Tech worked with the New York City Mayors Office of Environmental Remediation (NYCOER) to clear Noise “E” Designations assigned to a residential development in the Williamsburg section of Brooklyn following completion of construction. . Upon completion of the development and receipt of the Notice of Satisfaction for hazardous materials, the New York City Department of Environmental Protection (NYCDEP) notified the developer that special windows would be required to mitigate exterior noise. The property owner was faced with a dilemma because construction had already been completed and replacing windows would exceed the project budget.

Environmental Investigation and Remediation of a NYC Local Brownfield Cleanup Project

Hydro Tech Environmental assisted the client in applying to the New York City Brownfield Cleanup Program. At the time of the application the program was still in its development so Hydro Tech worked closely with the NYC officials to determine what type of investigation and remediation plans would be necessary to enter into the program.

Hudson and Canal

Manhattan, NY
NYC VCP Site and the Remediation of NYSDEC Spill During Site Development

The Site is approximately 12,937 square feet in area is located in the southwest portion of Manhattan. The current owner purchased this property for the development of a 10-story building. The Site was historically developed as a mixture of residential buildings and auto repair shops. Gasoline tanks were historically present on-site and the site was designated with a Hazmat/Noise “E”. During a subsurface investigation it was discovered that free product was floating on the groundwater, elevated levels of dissolved gasoline was present in the groundwater and levels of gasoline compounds were present in the soil. The NYSDEC was notified of the release and a NYSDEC Spill Number was assigned to the property. Hydro Tech then prepared a Remedial Action Work Plan (RAWP) which was approved by the New York City Office of Environmental Remediation (NYC OER) and a Notice to Proceed was issued.
