Case: Saint Lawrence River/Alcoa/GM, NY

Site History: This Site includes the General Motors Central Foundry Division, listed on the National Priorities List in 1984, as well as the Aluminum Company of America (ALCOA West) and Reynolds Metals Company (ALCOA East) facilities. The ALCOA West facility has produced aluminum from alumina using the pre-baked anode method since 1903. The Reynolds Metals Company was constructed in 1958 to produce aluminum from alumina using the soderberg process. General Motors Central Foundry manufactured aluminum cylinder heads at this plant beginning in 1959. Starting in the late 1950s polychlorinated biphenyls (PCBs) were used in hydraulic fluid and electrical equipment at both plants.

Location: Massena, New York.

Trustees:

Case status: The Trustees are conducting a cooperative natural resource damage assessment with Alcoa and GM to address injury to ecological, recreational fishing, and cultural services. Potential restoration project ideas are currently being solicited from the public Linking to a non-federal government web site.This link does not imply endorsement..

Overview: The Alcoa West (Grasse River plant), Alcoa East (former Reynolds Metals Company), and General Motors Foundry are located in Massena, New York. PCBs as well as metals (e.g., aluminum, fluoride, cyanide), polyaromatic hydrocarbons (PAHs), and dioxins and furans have been released into the surrounding environment including the Grasse River, the Raquette River, the St. Lawrence River, and Turtle Cove/Turtle Creek. Land- and river-based remediation has addressed some but not all of the source conditions. Records of Decision have been issued for the St. Lawrence River at GM and Reynolds, Turtle Cove, and the Raquette River. A remedy for the Grasse River has not yet been selected and supplemental remediation is pending for the Reynolds St. Lawrence remediation area.

The Trustees formed the St. Lawrence Environmental Trustee Council (SLETC) in 1990 to coordinate their activities resolving natural resource liability at these three sites. A Pre-assessment Screen was prepared by the SLETC in 1991. A cooperative assessment was initiated between the SLETC and the Companies in 2000. This process is an ongoing effort to assess injuries (by quantity or quality) to ecological resources such as sediment, fish, birds, mammals, reptiles and amphibians. There is also a parallel effort to quantify injury to recreational fishing and tribal cultural resources.
