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.
