manufactured gas plants
Manufactured Gas Plants Con Edison is working closely with state and local environmental and health officials to test and remediate, where appropriate, sites that were once home to Manufactured Gas Plants (MGPs). Existing from the early 1800s to mid 1900s, several of these New York sites are on properties owned or formerly owned by Con Edison or its predecessor companies. If you would like more information about MGPs, please call our toll-free information and response line, 1-877-602-6633.
Additional information on the history of MGPs in the U.S. is available at the New York State Department of Environmental Conservation.

E. 14th Street Works Site - East River Ball Fields Update
The State Department of Environmental Conservation held a press conference to announce that the cleanup of Pelham Plaza, a former manufactured gas plant site, is substantially complete. The cleanup will clear the way for the 20-acre parcel to become an economic asset.
DEC Commissioner Pete Grannis praised Con Edison for its role in the project. Randolph S. Price, Con Edison's Vice President for Environment, Health and Safety, noted that the company has received several honors for its environmental efforts.

Project Status and Schedule
Con Edison, in cooperation with the NYSDEC and NYSDOH, developed an Alternatives Analysis Report (AAR) to address subsurface residual contamination. After all comments received from the public were addressed, the AAR and remedy were finalized and approved by the NYSDEC and NYSDOH.
The approved remedy entails excavation of surface and subsurface soil from specific areas of the former site, in-place chemical oxidation of subsurface soil, oxygen enhanced biodegradation of dissolved MGP-related volatile chemicals in groundwater and sub-slab venting. In conjunction with these engineering controls, administrative controls, such as environmental easement, will also be enacted to ensure long term management of any residuals that remain in the subsurface after the remediation is complete and to prevent any potential future exposure to such conditions.
The remediation activities will be performed on portions of the Greater Centennial Homes Apartment complex along W. 5th Street, Vernon Arms Apartments, five previously private homes along S. 9th Ave., the vicinity of the bodega at S. 8th Ave. and W. 5th St. and Mt. Zion Christian Baptist Church. The project will begin in March 2010 and is expected to take 18 months to complete the work.

Kent Avenue Generating Station
The former Con Edison Kent Avenue Generating Station is located at 500 Kent Avenue, Brooklyn, New York. The total area of the Site is approximately 4 acres of which approximately 2.6 acres was the location of an electrical power generating station housed in a seven to nine story structure that was demolished in 2009. In January 2012, Con Edison completed an Interim Remedial Measure (IRM) to address the former Ash Pit and Pump House located in the northwestern portion of the Site. Starting in November 2013, Con Edison will begin the NYSDEC approved final remedy for the site. If you have a question or concern, Con Edison can be reached at 877-602-6633. Please leave a voice mail message and your call will be returned as soon as possible.

Con Edison operated the Hunts Point MGP Site as an MGP and gas holder station between 1926 and 1962. A large gas holder on the northern portion of the Gas Works was used until 1968, after which it was removed from service and demolished. The City of New York acquired the majority of the former Hunts Point Gas Work property in the late 1960s. The property was then transitioned into warehouse space for a wholesale food cooperative.
