Levin and Stabenow said Kerry should engage the International Joint Commission on the proposed dumping site, adding that since the lake is an internationally shared resource both countries should have to approve the underground facility.

“We believe that the decision to store such large quantities of nuclear waste along the shores of an internationally shared resource must be thoroughly reviewed and considered by both countries,” Levin and Stabenow wrote. “We strongly urge you to engage the International Joint Commission on this important topic and also encourage the Canadian government to reconsider placing a nuclear waste dump near the shores of Lake Huron.”

Canada needs a place to dump the waste from the Bruce nuclear power site. The proposed underground storage facility would hold more than 200,000 cubic feet of waste just 1 mile from the lake shore. The senators said the Canadian government could begin construction as early as 2014 since the project is currently under final review.
