Approval and Promulgation of Implementation Plans; Texas; Revisions to Regulations for Control of Air Pollution by Permits for New Sources and Modifications

The EPA proposes to approve revisions to the Texas State Implementation Plan (SIP) which the Texas Commission on Environmental Quality (TCEQ) submitted to EPA on February 5, 2004. The adopted amendments revise minimum distance limitation permit requirements for operation of new and modified sources to allow storage of an inoperative concrete crusher within 440 yards of a residence, school, or place of worship; define how distance measurements should be taken and when they would be applicable to concrete crushers and other facilities; and allow concrete crushers to recycle broken concrete at temporary demolition sites within 440 yards of nearby buildings, unless the facility is located in a county with a population of 2.4 million or more, or in a county adjacent to such a county. The TCEQ also revised the existing distance limitation for hazardous waste management facilities to cross-reference duplicative language elsewhere in its regulations. This action is being taken under section 110 of the Federal Clean Air Act (the Act, or CAA).
