USA: EPA Introduces Plan to Address Grasse River PCB Contamination

EPA Introduces Plan to Address Grasse River PCB Contamination

The U.S. Environmental Protection Agency has proposed a plan to clean up contaminated river sediment at the Grasse River Superfund site in Massena, New York.

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 onsite 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 gravel to isolate the contamination from the surrounding environment.

The EPA will hold several formal public meetings and informal information sessions in Akwesasne and Massena, N.Y. to discuss its plan. The EPA is encouraging the public to comment on the plan through November 15, 2012.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
