Stationary Source Rules for Various Counties and Statewide Rules
Rules for stationary sources in various parts of Texas that are part of the State Implementation Plan strategy to meet the National Ambient Air Quality Standards.
Controlling Ozone Pollution
Rules reduce ozone by limiting emissions of nitrogen oxides (NOx) and volatile organic compounds (VOCs) from the following stationary sources.

Controlling Particulate Matter Pollution
Statewide rules limit particulate matter emissions and opacity from affected stationary sources.
Controlling Sulfur Dioxide Pollution
Statewide rules limit sulfur dioxide emissions and ground level concentrations from affected stationary sources.
