Controlling NOx Emissions from Major Combustion Sources
Rules in Title 30, Texas Administrative Code, Chapter 117, for controlling emissions of nitrogen oxides from major industrial, commercial, and institutional sources in ozone nonattainment areas. These rules are part of the State Implementation Plan strategy to meet the National Ambient Air Quality Standard for ozone.
Areas Affected
- Beaumont–Port Arthur area (Hardin, Jefferson, and Orange Counties)
- Dallas–Fort Worth area (Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, Tarrant, and Wise Counties)
- Houston-Galveston-Brazoria area (Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller Counties)
Rule Citation
30 TAC Chapter 117, Subchapter B
Rule Description
- These rules are intended to reduce NOx emissions from the following combustion sources:
- boilers;
- gas turbines and duct burners used in turbine exhaust ducts;
- process heaters and furnaces;
- stationary internal combustion engines;
- brick, ceramic, and lime kilns;
- incinerators;
- metallurgical heat-treating and reheat furnaces;
- lead-smelting blast (cupola) and reverberatory furnaces;
- glass-melting furnaces;
- melting furnaces for fiberglass and mineral wool fiber;
- curing ovens for fiberglass and wool fiber; and
- heaters, and ovens; and
- dryers used in organic solvent, printing ink, clay, brick, ceramic tile, calcining, and vitrifying processes.
- Monitoring, reporting, recordkeeping, and testing requirements may apply depending on the size of the unit and its particular use.
- Final control plans demonstrating compliance with the emission specifications may also apply.
Rule History
The Chapter 117 rule history for major industrial, commercial, and institutional sources gives information on revisions to the rules, including the rule proposal and adoption, the associated state implementation plan revision, and the U.S. Environmental Protection Agency approval of the rules.
