Air Programs and Issues in Texas

The Clean Air Act (CAA) establishes a number of permitting programs designed to carry out the goals of the act.  Some of these programs are directly implemented by EPA's South Central Region (Region 6), but most are carried out by the Texas Commission on Environmental Quality (TCEQ). Exit

Transcript of Webinar

Original invitation to the Webinar

Regional Haze

EPA partially approved and partially disapproved the Texas regional haze plan. EPA also finalized a plan to limit sulfur dioxide emissions from eight Texas coal-fired electricity generating facilities as part of satisfying the reasonable progress and long-term strategy requirements for improving visibility at the Wichita Mountains National Wildlife Refuge in Oklahoma, and Big Bend and the Guadalupe Mountains National Parks in Texas.

EPA proposed a clean-air plan for the State of Texas to meet the Regional Haze BART and Interstate Visibility Transport requirements of the Clean Air Act and set January 10, 2017 as the date for a public hearing.

Air Permitting in Texas

EPA finalized its conditional approval of the Texas Flexible Permit program.

The EPA and Texas collaborated to identify what additional elements were needed for an updated rule to meet all Clean Air Act requirements. The final rule establishes an air permitting program where emissions caps for air pollutants can be utilized to help minimize emissions while protecting human health and the environment. The rules also are enforceable and compliance must be demonstrated.

The EPA is reopening the original public comment period for the proposed full approval of the Texas Flexible Permit Program for 30 additional days beginning April 17, 2015 because we neglected to include two supporting materials in Docket. No. EPA-R06-OAR-2013-0542 Exit at Exit.
