EPA Greenlights Texas Plan to Curb Dallas Smog Emissions
Published Date: 7/24/2025
Proposed Rule
Summary
The EPA is giving a thumbs-up to Texas’ plan to cut pollution from big sources in the Dallas-Fort Worth area to help clean up the air. This update focuses on controlling nitrogen oxide emissions, which contribute to smog, and is part of a bigger effort to meet air quality goals. Businesses in the area might need to follow new rules soon, but it’s all about making the air healthier without breaking the bank.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
New NOx Controls for Big Emitters
The EPA is proposing to approve Texas’ May 12–13, 2020 revisions to 30 TAC Chapter 117 that implement the major-source Reasonably Available Control Technology (RACT) requirement for nitrogen oxides (NOx) in the Dallas–Fort Worth Serious ozone nonattainment area for the 2008 ozone NAAQS. If you operate a major emitting facility in Dallas–Fort Worth, you may need to follow new RACT requirements to control NOx emissions once the plan is finalized.
Cleaner Air for Dallas–Fort Worth Residents
The EPA’s proposed approval supports cutting nitrogen oxides (NOx) in the Dallas–Fort Worth area to help meet the 2008 ozone National Ambient Air Quality Standard and clean up the air. If you live in Texas, especially in the Dallas–Fort Worth area, this action is intended to improve local air quality by reducing smog-forming emissions.

2026-13667, Minor New Source Review Program Air Permitting Public Participation Requirements for State Implementation Plans
The EPA wants to give states more freedom to decide how much public input is needed when approving small air pollution sources or changes. This means local air agencies can tailor public participation to fit their community’s needs while still protecting air quality. If you’re involved in air permits, watch for comment deadlines and possible virtual hearings this summer!
2026-13263, Revisions To Establish the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) for Public Water Systems
The EPA is rolling out the sixth Unregulated Contaminant Monitoring Rule (UCMR 6) to check for new, sneaky chemicals in public drinking water. Big water systems serving 3,300+ people and some smaller ones will test for 30 different contaminants, including certain PFAS and pesticides, to keep our water safe. Comments and feedback are open until late August 2026, and the EPA will host fun online meetings to chat about the plan!
