The EPA is taking direct final action to approve revisions to the Texas State Implementation Plan (SIP). This rulemaking covers four separate actions approving revisions to the Texas Rules for Control of Air Pollution from Volatile Organic Compounds (VOC Rules), 30 TAC Chapter 115. First, EPA is approving amendments to sections 115.161, 115.162, 115.164-115.167, and 115.169, concerning Batch Processes. Second, EPA is approving amendments to sections 115.120, 115.122, 115.125-115.127, and 115.129, concerning control requirements for bakeries and testing requirements for vents. Third, we are approving amendments to section 115.449, concerning Offset Lithographic Printing. Finally, EPA is approving numerous minor administrative changes to the VOC rules. The Texas Natural Resource Conservation Commission (TNRCC or Commission) adopted these revisions to Chapter 115, concerning Control of Air Pollution from Volatile Organic Compounds (VOC), and to the State Implementation Plan (SIP) in order to meet the Clean Air Act (Act) Reasonably Available Control Technology (RACT) requirements and to control VOC emissions in the Houston/Galveston ozone nonattainment area (HGA). By approving these SIP revisions, EPA is finding that RACT will be implemented for VOC emissions resulting from the operation of batch processes, bakeries (vent gas control), and offset lithography printing sources in the HGA area accordance with the requirements of the Act. In addition, the changes to test methods for vent gas control and various other minor changes will clarify and strengthen the SIP.
