EPA is taking direct final action approving Texas State Implementation Plan (SIP) revisions. The revisions pertain to Reid Vapor Pressure (RVP) requirements for gasoline. The revisions add exemptions to RVP requirements for research laboratories and academic institutions, competition racing, and gasoline that is being stored or transferred that is not used in the affected counties. The revisions also reduce recordkeeping requirements for retail gasoline dispensing outlets in the affected counties, and correct a typographical error. We are approving the revisions pursuant to section 110 and part D of the Federal Clean Air Act (CAA).
