Approval of Air Plans; California; Multiple Districts; Prevention of Significant Deterioration

The EPA is proposing approval of five permitting rules submitted for inclusion in the California State Implementation Plan (SIP). The State of California (State) is required under the Clean Air Act (CAA or Act) to adopt and implement a SIP-approved Prevention of Significant Deterioration (PSD) permit program. This SIP revision proposes to incorporate PSD rules for five local California air districts into the SIP to establish a PSD permit program for pre- construction review of certain new and modified major stationary sources in attainment and unclassifiable areas. The local air districts with PSD rules that are the subject of this proposal are the Feather River Air Quality Management District (Feather River or FRAQMD), Great Basin Unified Air Pollution Control District (Great Basin or GBUAPCD), Butte County Air Quality Management District (Butte or BCAQMD), Santa Barbara County Air Pollution Control District (Santa Barbara or SBAPCD), and San Luis Obispo County Air Pollution Control District (San Luis Obispo or SLOAPCD)--collectively, the Districts. We are soliciting public comment on this proposal and plan to follow with a final action after consideration of comments received.
