MASSENA - The Saint Regis Mohawk Tribe does not agree with the U.S. Environmental Protection Agencys (EPA) proposed plan to clean up the Grasse River.
We appreciate EPAs recognition of the Indian Meadows as reservation lands and the recognition of our status as an Environmental Justice community because of the disproportionate impact on this community from the contamination of the Grasse River. But we do not totally agree with their cleanup plan, said the tribes Environment Division Director Ken Jock. We do support dredging of the entire near shore area of the Grasse River — everything along the banks to five feet in depth.
Past industrial activity from the Alcoa West facility contaminated the Grasse River with polychlorinated biphenyls (PCBs), which are found in hydraulic fluids. Other hazardous substances were also released and approximately seven miles of the Grasse River have been contaminated. As a result, these chemicals have built up in the food chain and affected the fish and wildlife associated with the river. The consumption of local fish has had well-documented adverse health effects on the Saint Regis Mohawk Tribe. The tribe is proposing a more pro-active approach to the remediation of the Grasse River.
Capping is not a permanent remedy and ice scour is a constant threat to any cap in the Grasse River, Mr. Jock said. Therefore we do not support the capping of the highly contaminated sediments in main channel, he added. Nobody has any real-world evidence that a cap can withstand a major ice jam and ice scour. The pilot studies conducted about capping showed that they were not successful in achieving a uniform capping layer. The problem is worse here because it is in a dynamic river with spring ice jams, floods, scour and erosion.
The tribe is looking to remediate the river to be able to restore the habitat and achieve a safe fishery in the Grasse River. This would not only benefit the Saint Regis Mohawk Tribe, it would benefit the entire region, noted Tribal Chief Randy Hart.
Both the local and downstream areas would be improved, he said, explaining habitat restoration would allow people to consume fish, trap and gather plants that grow near the water.
We do not support the capping of the main channels highly contaminated sediments just as we do not support a cap over the GM dump, explained Tribal Chief Ron LaFrance. The cap in the river would leave about 93 percent of the contaminated sediments in the river bottom.
