Summary
This regulation sets rules for Texas to reduce sulfur dioxide pollution from power plants and industrial sources to meet federal air quality standards. The rule ensures that Texas's pollution controls don't harm air quality in neighboring states and protects people from breathing harmful sulfur dioxide, which causes respiratory problems.
Key Points
- 1Texas must limit sulfur dioxide emissions to meet a federal air quality standard set in 2010, which is stricter than previous standards
- 2The rule requires Texas to show that its pollution from power plants and factories won't blow across state lines and damage air quality in neighboring states
- 3Power plants and industrial facilities in Texas may need to install better pollution control equipment or reduce their operations to meet these limits
- 4The regulation protects people with asthma, children, and the elderly who are most vulnerable to sulfur dioxide-related respiratory problems
- 5States that don't comply with these interstate transport rules risk losing federal highway funding and facing restrictions on new industrial projects
