40 CFR Parts 50, 51, 70, and 71 - Reconsideration of Interpretation of Regulations That Determine Pollutants Covered by Clean Air Act Permitting Programs; Final Rule

• Date: May 05, 2010

EPA has made a final decision to continue applying the Agency’s existing interpretation of a regulation that determines the scope of pollutants subject to the Federal Prevention of Significant Deterioration (PSD) program under the Clean Air Act (CAA or Act). In a December 18, 2008 memorandum, EPA established an interpretation clarifying the scope of the phrase ‘‘subject to regulation’’ found within the definition of the term ‘‘regulated NSR pollutant.’’ After considering comments on alternate interpretations of this term, EPA has decided to continue to interpret it to include each pollutant subject to either a provision in the CAA or regulation adopted by EPA under the CAA that requires actual control of emissions of that pollutant. Thus, this action explains that EPA will continue following the interpretation in the December 18, 2008 memorandum with one exception. EPA is refining its interpretation to establish that the PSD permitting requirements will not apply to a newly regulated pollutant until a regulatory requirement to control emissions of that pollutant ‘‘takes effect.’’ In addition, this notice addresses several questions regarding the applicability of the PSD and Title V permitting programs to greenhouse gases (GHGs) upon the anticipated promulgation of EPA regulations establishing limitations on emissions of GHGs from vehicles under Title II of the CAA. Collectively, these conclusions result in an EPA determination that PSD and Title V permitting requirements will not apply to GHGs until at least January 2, 2011.

DATES: This final action is applicable as of March 29, 2010.
