## Abstract

EPA is finalizing limited approvals of revisions to the California State Implementation Plan (SIP) proposed in the Federal Register on March 18, 1999. This final action will incorporate these rules into the federally approved SIP. The intended effect of finalizing this action is to regulate emissions of sulfur dioxide (SO<INF>2</INF>) in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). The rules control the sulfur content of fuels within the South Coast Air Quality Management District and the Siskiyou County Air Pollution Control District, emissions of sulfuric acid mist within the San Joaquin Valley Unified Air Pollution Control District and emissions of sulfur dioxide in the Bay Area Air Quality Management District. Thus, EPA is finalizing a limited approval under CAA provisions regarding EPA action on SIP submittals and general rulemaking authority because these revisions, while strengthening the SIP, also do not fully meet the CAA provisions regarding plan submissions. There will be no sanctions clock as South Coast Air Quality Management District, San Joaquin Valley Unified Air Pollution Control District, Siskiyou County Air Pollution Control District, and Bay Area Air Quality Management District are in attainment for SO<INF>2</INF>.
