**Revision of Air Quality Implementation Plan; California; Placer County Air**  **Pollution Control District and Feather River Air Quality Management District;**  **Stationary Source Permits**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  EPA is proposing a limited approval and limited disapproval of permitting rules submitted by California as a revision to the Placer County Air Pollution Control District (PCAPCD) and Feather River Air Quality Management District (FRAQMD) portion of the California State Implementation Plan (SIP). These rules were adopted by the PCAPCD and FRAQMD to regulate the construction and modification of stationary sources of air pollution within each District. EPA is proposing to approve these SIP revisions based on the Agency’s conclusion that the rules are consistent with applicable Clean Air Act (CAA) requirements, policies and guidance. Final approval of these rules would make the rules federally enforceable and correct program deficiencies identified in a previous EPA rulemaking (76 FR 44809, July 27, 2011).
