EPA Technical Support Document Texas DFW Ozone RACT

This document provides technical support for the EPA's evaluation of Texas's State Implementation Plan (SIP) revisions concerning Reasonably Available Control Technology (RACT) for ozone in the Dallas-Fort Worth (DFW) nonattainment area. It details the EPA's analysis of emissions sources and control measures to ensure compliance with National Ambient Air Quality Standards (NAAQS) for ozone.

Regulated entities, particularly in the energy and manufacturing sectors within the Texas DFW area, should review this technical support document to understand the EPA's rationale and potential implications for their emissions control strategies. While this is a support document and not a rule itself, it informs the finalization of SIPs, which will impose binding requirements. Companies should ensure their control technologies and emissions reporting align with the analyses presented to prepare for potential future regulatory actions or SIP revisions.
