MASSENA - The St. Regis Mohawk Tribal Government is opposed to the Environmental Protection Agencys proposed $243 million cleanup of the Grasse River.
The tribal government issued a statement late Tuesday afternoon declaring its opposition to the EPA plan Monday. The plan recommends dredging approximately 109,000 cubic yards of contaminated sediment in areas close to the shore. In the rivers center, approximately 225 acres of sediment would be capped with clean sand and gravel to isolate the contamination. Another 59 acres would receive an additional armored cap of large rocks to further isolate that areas contamination.
The EPA explored 10 different cleanup alternatives, ranging from a do-nothing option costing nothing to one costing nearly $1 billion, spokeswoman Larisa W. Romanowski said previously. Alcoa, which had caused the contamination decades earlier, will fund which ever option is chosen.
Several alternatives were in the $200 million to $300 million range and involved a combination of dredging and capping contaminated areas of the river.
EPA chose the $243 million option because it best fulfilled the agencys mission to protect human health and the environment, Ms. Romanowski said.
But Mohawk officials say capping is not an adequate method of cleaning up the river.
Capping is not a permanent remedy and ice scour is a constant threat to any cap in the Grasse River, Ken Jock, director of the tribal governments environment division, said in a statement. Therefore we do not support the capping of the highly contaminated sediments in main channel.
We do support dredging of the entire near shore area of the Grasse River - everything along the banks to five feet in depth, Mr. Jock said. Nobody has any real-world evidence that a cap can withstand a major ice jam and ice scour.
The Mohawk environment divisions conclusions differ from Alcoas; company officials said their 15 years and $65 million in research indicated capping would be protective of human health and the environment and allow the Grasses natural restoration to continue.
But Mohawk officials contend that capping would not eliminate the industrial pollutants which are still in the river.
We do not support the capping of the main channels highly contaminated sediments just as we do not support a cap over the (General Motors) dump, Tribal Council Chief Ronald W. LaFrance said. The cap in the river would leave about 93 percent of the contaminated sediments in the river bottom.
Mohawk officials did not extensively detail their preferred cleanup proposal in Tuesdays release, but said their plan would restore the Grasse Rivers habitat and achieve a safe fishery. The rivers pollutants have affected the rivers wildlife, which in turn have created well documented health effects on the reservation population, which fishes locally.
This would not only benefit the St. Regis Mohawk Tribe, it would benefit the entire region, Tribal Chief Randy Hart said. Both the local and downstream areas would be improved.
If the Mohawks plan involved additional dredging, it would likely drive up the cost. On Monday, Sen. Charles E. Schumer had praised EPAs preferred option because it was a balanced way to clean the Grasse River and protect public health without breaking the bank. He was hopeful the projects costs would give Alcoa the confidence necessary to push forward with a modernization of its Massena operations, an investment of at least $600 million in the community.
In an August visit, Mr. Schumer said Alcoa could push forward with the modernization if it received a good reasonable settlement on the cleanup. On Monday, Alcoa spokeswoman Laurie A. Marr down played the role between the cleanup and the modernization, calling them two separate projects with different timelines.
The EPA is accepting public comment until Nov. 15 and will finalize its cleanup plan after that. Mr. LaFrance could not be reached for further comment Tuesday night.
