The House Energy and Commerce Committee is poised to approve a piecemeal overhaul of the Clean Air Act this week, albeit in the face of what will likely be unified Democratic resistance.

Also on the agenda is the House version of a bipartisan hydropower measure that unanimously cleared the Senate last year and another bill that would strip EPA of its authority to review highway construction projects already subject to review under the National Environmental Policy Act.
