Senate showdown over EPA climate rules scheduled for June 10

The Senate is slated to vote June 10 on a resolution by Sen. Lisa MurkowskiLisa Ann MurkowskiTrump budget includes proposal for US Consulate in Greenland Democrats worried about Trump's growing strength The Hill's Morning Report — AG Barr, GOP senators try to rein Trump in MORE (R-Alaska) that would strip the Environmental Protection Agency’s power to regulate greenhouse gas emissions, according to Murkowski’s office.

Monday night on bringing the filibuster-proof resolution to the floor next month, with a vote expected June 10.

Murkowski has 40 co-sponsors — including centrist Democrats Ben Nelson (Neb.) and Blanche Lincoln (Ark.) — for the plan.

Murkowski’s plan overturns EPA’s “endangerment finding” last year that greenhouse gases pose a threat to humans. The finding is the legal precursor to EPA rules that limit heat-trapping emissions from cars, power plants, factories and other sources.

Reid's office did not provide immediate comment Tuesday morning.

Murkowski is bringing up the measure under the little-used Congressional Review Act, which gives Congress the power to block federal regulations but has been used successfully just once.

Resolutions under the act are immune from filibuster, but it remains highly uncertain whether Murkowski can corral 10 more votes — especially if lawmakers can find cover by backing less aggressive alternatives.

Also, even if the measure cleared the Senate, advocates of blocking EPA would have to force a vote on companion House legislation. Murkowski’s plan faces a near-certain veto if it got that far — the White House has repeatedly criticized her resolution.

Murkowski alleges that EPA regulation under its existing Clean Air Act powers will have harmful economic effects. The EPA, under recently finalized rules, will begin phasing in greenhouse gas permit requirements for large sources like coal-fired power plants and refineries next year.

But Murkowski fears that the EPA will eventually impose burdensome rules across a wide swath of the economy, and does not believe that EPA’s plan to limit the regulations to large emitters will hold up in court.
