Supreme Court limits GHG regs for stationary sources

摘要

The Tailoring Rule, one of EPA's major actions following the Supreme Court's opinion in Massachusetts v. EPA, did not escape intact following the Court's second look at the Agency's program for greenhouse gas (GHG) emissions from stationary sources. In a 5-to-4 opinion, the majority found that the Agency overstepped its authority under the Clean Air Act (CAA) by setting new GHG emissions limits for stationary sources under CAA's Prevention of Significant Deterioration (PSD) and Title V permitting programs when those sources are not already subject to such permitting (Utility Air Regulatory Group v. Environmental Protection Agency et al).
