A House Republican wants to limit the Environmental Protection Agency’s (EPA) power to scuttle “mountaintop removal” coal-mining projects when lawmakers debate a major water infrastructure bill this week.

Rep. David McKinley (R-W.Va.) is floating an amendment to the Water Resources Reform and Development Act (WRRDA) that would prevent EPA from “retroactively” vetoing water pollution permits granted by the U.S. Army Corps of Engineers.

It’s the latest effort by Republicans and coal-state Democrats to limit EPA after the agency’s 2011 veto of a permit for Arch Coal Inc.’s big Spruce No. 1 mine in West Virginia, which the U.S. Army Corps of Engineers granted in 2007.
