## Abstract

The Environmental Protection Agency (EPA) is finalizing approval of a portion of a state implementation plan (SIP) submission from the State of California regarding Clean Air Act (CAA or "Act") requirements for ambient ozone monitoring in the Bakersfield Metropolitan Statistical Area (MSA) for the 1997 ozone and 2008 ozone national ambient air quality standards (NAAQS or "standards"). The SIP submission is intended to revise a portion of the State's "infrastructure" SIP that, more broadly, provides for implementation, maintenance, and enforcement of the standards.
