EPA Final Rule: Texas DFW Ozone NOx RACT Technical Support Document

The Environmental Protection Agency (EPA) has finalized its Technical Support Document (TSD) concerning the Reasonably Available Control Technology (RACT) requirements for Nitrogen Oxide (NOx) emissions in the Texas Dallas-Fort Worth (DFW) Ozone Non-attainment Area. This final TSD outlines the agency's technical findings and rationale for approving or disapproving specific control measures proposed by Texas to meet federal air quality standards for ozone.

This final rule establishes binding requirements for affected entities in the DFW area. Companies identified as major sources of NOx emissions must ensure their operations comply with the control measures detailed in the TSD. While a specific compliance deadline is not provided in this document, regulated entities should review the TSD to understand the applicable NOx emission limits and control technologies required to meet the Clean Air Act's objectives for ozone reduction. Non-compliance may result in enforcement actions by the EPA or state agencies.
