Approval and Promulgation of Implementation Plan; Texas; Revisions to 30 TAC Chapter 115 for Control of Volatile Organic Emissions From Perchloroethylene Dry Cleaning Systems

The EPA is approving revisions to the State Implementation Plan (SIP) in order to repeal rules which are no longer required. The requirements of 30 TAC Chapter 115, sections 115.521-115.527 and 115.529 for controlling emissions from perchloroethylene (perc) dry cleaners are being repealed. In a February 7, 1996, Federal Register action, for purposes of preparing SIP's to attain the national ambient air quality standards (NAAQS) for ozone under title I of the Clean Air Act (Act), EPA excluded perc from the Federal definition of Volatile Organic Compound (VOC) due to perc's negligible photochemical reactivity. Emissions from perc dry cleaners will continue to be regulated by the perc dry cleaning National Emission Standards for Hazardous Air Pollutants which EPA promulgated on September 22, 1993.
