## Abstract

EPA is taking direct final action on revisions to the California State Implementation Plan. The revisions concern rules from the Ventura County Air Pollution Control District (VCAPCD), the Sacramento Metropolitan Air Quality Management Division (SMAQMD), and the Placer County Air Pollution Control District (PCAPCD). This approval action will incorporate three rules into the federally approved SIP. The intended effect of approving these rules is to regulate emissions of oxides of nitrogen (NO<INF>X) in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). The rules control NO<INF>X emissions from natural gas-fired central furnaces, stationary internal combustion engines, and biomass boilers.
