The EPA is taking direct final action approving revisions to the Texas Natural Resource Conservation Commission (TNRCC) regulations in the Texas State Implementation Plan (SIP). These revisions remove the Texas Air Control Board (TACB) Seal rule from the Texas SIP and revise and recodify regulations for control of particulate matter in the Texas SIP. Removal of the Board Seal rule eliminates a rule that no longer applies to TNRCC. These revisions to the particulate matter regulations update the SIP-approved regulations and make the SIP citations consistent with the current State citations.
