## Abstract

EPA is taking direct final action to approve revisions to the San Diego Air Pollution Control District (SDAPCD), Northern Sierra Air Quality Management District (NSAQMD), and Sacramento Metropolitan Air Quality Management District (SMAQMD) portions of the California State Implementation Plan (SIP). These revisions concern volatile organic compound (VOC) emissions from the transfer of gasoline at gasoline dispensing facilities. We are approving local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
