## Abstract

EPA is taking direct final action to approve revisions to the Monterey Bay Unified Air Pollution Control District (MBUAPCD) and the Ventura County Air Pollution Control District (VCAPCD) portions 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 local rules that address general requirements for continuous emissions monitoring systems and the use of credible evidence to demonstrate compliance with emission limits under the Act.
