MASSENA -- The Environmental Protection Agency is looking for public comment on the proposed plan to clean up the Grasse River.
The EPA has proposed a plan to clean up contaminated river sediment at the Grasse River Superfund site. Past industrial activities have contaminated the river sediment with polychlorinated biphenyls (PCBs), which are potentially cancer-causing chemicals that build up in the food chain and accumulate in the fatty tissue of fish and mammals.
The proposed plan requires dredging and capping of contaminated sediment in a 7.2 mile stretch of river. Approximately 109,000 cubic yards of PCB-contaminated sediment would be dredged from near-shore areas of the river and backfilled with clean material.
Dredged sediment would be disposed of at a permitted, secure on-site landfill.
In the river’s main channel, approximately 59 acres of contaminated sediment would be covered with an armored cap and another approximately 225 acres of contaminated sediment would be capped with clean sand and topsoil to isolate the contamination from the surrounding environment.
The EPA is encouraging the public to comment on the plan through Nov. 29. Written comments on EPA’s proposed plan may be mailed or emailed to:
Young S. Chang, Remedial Project Manager U.S. Environmental Protection Agency, 290 Broadway, 20th Floor, New York, NY 10007-1866 or chang.young@epa.gov.
