Approval and Promulgation of Air Quality Plans, Texas; Alternate Reasonably Available Control Technology Demonstration for Bell Helicopter Textron, Incorporated; Bell Plant 1 Facility

The EPA is approving a site specific revision to the Texas State Implementation Plan (SIP) for Bell Helicopter Textron, Incorporated (Bell) of Fort Worth. This revision was submitted by the Governor on April 18, 1996, to establish an alternate reasonably available control technology (ARACT) demonstration to control volatile organic compounds (VOC) for the surface coating processes at the Bell Plant 1 facility. The EPA has determined that the control strategy, solvent and coating emission limits, submitted by Bell and the Texas Natural Resource Conservation Commission (TNRCC), demonstrate Reasonably Available Control Technology (RACT) for the Bell Plant 1 facility. This ARACT demonstration is approvable because Bell has demonstrated that it is not cost effective to control their VOC emissions to the presumptive norm set forth in the EPA's Control Technique Guidelines (CTG) document (EPA 450/2-78-015), and the alternate emission rate at the facility is the lowest that is economically reasonable and technically feasible.
