Committee rosters are set, oversight plans are signed, and witnesses are being called up to the Hill. For congressional Republicans, it's regulation-hunting season.
Republicans have made no secret of their plans to swipe at what they've deemed an overly burdensome environmental agenda from the Obama administration, and the change in power in the Senate provides both some new turf and leverage to do it. That effort kicked off in earnest Wednesday when the House Transportation and Infrastructure and Senate Environment and Public Works committees teamed up for a joint hearing to grill Environmental Protection Agency Administrator Gina McCarthy on the agency's proposed expansion of its Clean Water Act authority.
Here are 10 administration rules that will be in the GOP's sights this year:
1. The Clean Power Plan
The tent pole of the Obama administration's climate action plan, EPA's plans to curb greenhouse-gas emissions from new and existing power plants will face challenges on all fronts. EPA will finalize the rules in one package this summer, but the congressional challenges will come early and often. Environment and Public Works and the House Energy and Commerce Committee have both said they'll hold hearings on it and legislators are already looking to the appropriations process to kill the rules. No less than Senate majority leader Mitch McConnell put himself on the Appropriations subpanel that oversees EPA, with a promise to "continue to fight back against this administration's anti-coal jobs regulations on behalf of the Kentuckians I represent." A Congressional Review Act attack is also a possibility, but that can't come until the rules are finalized this summer.
