Sen. David Vitter (R-La.), the top Republican on the Senate’s environment committee, blamed the Environmental Protection Agency Monday after a major mining company abandoned the business partnership seeking build a huge copper and gold mine in Alaska.

“This is a prime example of why the economy isn’t recovering. EPA and their far-left environmental allies are using unprecedented tactics to shut down potential projects and corresponding jobs before they’ve even begun the permitting process,” Vitter said after mining giant Anglo American abandoned the proposed Pebble Mine.

Vitter, who is ranking member of the Environment and Public Works Committee, and some other Republicans say EPA is mishandling the project, taking aim in particular at a major assessment of the impact of mining in Alaska’s Bristol Bay watershed.
