## Abstract

EPA is finalizing approval of revisions to the Operating Permits (Title V) programs of the Monterey Bay Unified Air Pollution Control District (MBUAPCD), San Luis Obispo County Air Pollution Control District (SLOCAPCD), Santa Barbara County Air Pollution Control District (SBCAPCD), South Coast Air Quality Management District (SCAQMD), and Ventura County Air Pollution Control District (VCAPCD). We proposed these program revisions in the Federal Register on March 21, 2012. These revisions require sources with the potential to emit (PTE) of greenhouse gases (GHGs) above the thresholds in EPA's Tailoring Rule, which have not been previously subject to Title V for other reasons, to obtain a Title V permit. See "Prevention of Significant Deterioration and Title V Greenhouse Gas Tailoring Rule; Final Rule," (the Tailoring Rule) (75 FR 31514, June 3, 2010).
