On June 3, 2010, the USEPA issued its final Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule (75 FR 31,514). On the very same day, a legal foundation, House Republicans, businesses and business organizations sued the EPA saying EPA does not have the authority to issue the new rule.
The tailoring rule phases the applicability criteria to determine which stationary sources become subject to GHG emission permitting requirements under PSD and Title V Clean Air Act programs.
