## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve a revision to the California State Implementation Plan (SIP) for ozone for the San Joaquin Valley, which was submitted to EPA on March 2, 1995. This direct final approval action approves the ``Railroad Grade Separations'' transportation control measure (TCM) adopted by the State of California on January 13, 1995. This TCM supersedes the ``Controls on Extended Vehicle Idling'' transportation control measure (TCM) in the federally-approved 1982 California ozone SIP. The intended effect of direct final approval of this SIP revision is to control emissions of ozone precursors and carbon monoxide in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or 1990 Act).
