## Abstract

EPA is taking direct final action to approve revisions to the Imperial County Air Pollution Control District (ICAPCD) and the Mendocino County Air Quality Management District (MCAQMD), and to rescind one rule from the Monterey Bay Unified Air Pollution Control District (MBUAPCD) portion of the California State Implementation Plan (SIP). Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), we are approving and rescinding local rules that are administrative and address changes for clarity and consistency.
