Con Ed to begin work on gas plant remediation wells

Stuyvesant Town and Peter Cooper Village residents appeared more concerned about communication regarding Con Edison’s plan to dispose of toxic waste left behind from the property’s days as a manufactured gas plant than about the project itself during an information session hosted in Stuy Town last Thursday evening.

“We understand that it has to be done,” resident Sherry Kirschenbaum said. “Rick (Hayduk, the property’s general manager) said they will be working with Con Edison throughout the project. Our concerns were allayed.”

Con Ed expects the wells to remain in place for the foreseeable future but representatives said the most disruptive part of the project will be the drilling.

“We’ll be starting the drilling (during the day) once people are already at work and at school and the sonic drill rake we use is more of a hum,” Con Edison engineer Ken Kaiser said. “If there are complaints about noise, we could use some kind of baffling to muffle the sound.”

DEC: Contaminant recovery wells won’t be intrusive

With a contaminant recovery plan having been proposed for Stuyvesant Town and Peter Cooper Village, representatives from the State Department of Environmental Conservation (DEC) addressed concerns of residents last week at a public meeting.

This included making assurances that wells the DEC and Con Edison plan to build in ST/PCV to collect the leftover chemicals so they can be disposed of wouldn’t be intrusive. Con Ed has been working with DEC on what’s been referred to as a “remediation” for the site, which was once home to a manufactured gas plant (MGP).

The DEC had actually directed Con Edison to begin remediation for this project back in 2011. However, DEC project manager Doug MacNeal said during the meeting that the process was delayed for the last five years because of the changes in ownership at ST/PCV.

MacNeal said that exact locations haven’t been determined for the wells yet, but Council Member Dan Garodnick, who was also at the meeting, which held at Beth Israel last Wednesday, said that he would push DEC to site them as far away as possible from doors, windows and playgrounds.

One possible location for the wells, of which there will be 10 in Peter Cooper and six in Stuy Town, would be inside the garages. Meeting attendees burst into laughter when geologist and DEC project manager Gardiner Cross said that this was because the garages already have good ventilation. However, MacNeal backed up his statement, explaining that to be up to code, a garage has to have a functional ventilation system. If it doesn’t, he added, residents should contact DEC.

Manufactured gas plant investigation resumes in ST/PCV

After a two-year break, Con Ed this week resumed an ongoing study of Stuyvesant Town and Peter Cooper Village for manufactured gas plant (MGP) impacts and contaminants.
The utility noted on its website earlier this week that it would be doing indoor air testing from March 10-14 in certain buildings in ST/PCV.
The work was described as a routine part of its investigation of the complex, formerly home to MGP sites at East 14th Street, East 17th Street, East 19th Street and East 21st Street.
The former 21st Street Works MGP site occupied two thirds of the space that’s now Peter Cooper Village. Impacts have also been found in Stuyvesant Cove Park.
In its online notice (at coned.com/mgp), the company provided a list of addresses where testing would be done. In Peter Cooper Village, the testing sites are at all 21 buildings. In Stuyvesant Town, the testings sites are at 16 Stuyvesant Oval, 245 Avenue C, 522 and 524 East 20th Street and 615, 625, 635 and 645 East 14th Street.
Any contaminants and impacts are all leftovers from the days when ST/PCV was known as the Gashouse District, home to gas plants and holders where coal and oil was converted into gas for heating, lighting and cooking.
Con Ed’s manufacturing and storage of gas began in the 1840s and continued for a century until the property was sold to Metropolitan Life. Byproducts of the gas conversion included tar and purifier wastes, which were materials formed during the process before the gas was given to customers.
The last time Con Ed did investigation work on the property was in February of 2012 when it also did an indoor air study. Prior to that, in 2011, the company said it was looking at ways to “remediate” or clean up Peter Cooper Village, which was more heavily impacted by MGPs than Stuyvesant Town. However, no plan was ever announced. Con Ed is working with the New York State Department of Environmental Conservation and the NYS Department of Health on the project, which began in 2006.
When asked about the ongoing work and plan for remediation, a spokesperson for Con Ed, Bob McGee, said the investigations at the four MGP sites in ST/PCV have already been completed. Though he didn’t share the results, he did say that reports have been submitted to the NYSDEC.
“Con Ed has submitted alternative analysis reports for each site that analyzes potential remedial alternatives,” said McGee in a written statement. “NYSDEC has reviewed these reports and is in the process of preparing draft Decision Documents for each site that will present NYSDEC’s proposed remedial alternative. When these Decision Documents are complete they will be issued for public comment and a public hearing will be held. After NYSDEC considers public comments they will issue a final Decision Documents presenting the remedy that Con Ed must implement.”
The purpose of the study is to determine the potential hazards of human exposure to contaminants that could happen through breathing, ingesting or touching them.
Con Ed has said that because the contaminants have been found two feet or below the surface of the ground, the public is not expected to come into contact with them.
Exposure to contaminated groundwater is also unlikely, the company has said, because residents are served by a municipal water system.
