Relating to establishment of maximum allowable ground level concentrations of hydrogen sulfide by the Texas Commission on Environmental Quality.

HB 1341 requires the Texas Commission on Environmental Quality (TCEQ) to establish and enforce maximum allowable ground-level concentrations of hydrogen sulfide (H₂S) in the air. It sets stricter limits (0.04 parts per million averaged over 30 minutes) for areas used for residential, recreational, business, or commercial purposes, and slightly higher limits (0.06 ppm) for agricultural or other non-residential areas. The TCEQ must review and update these limits at least every five years based on the latest health studies. The bill also classifies violations as "major significance" under state water code rules, with rules required to be adopted by September 1, 2026. This directly affects residents, businesses, and industrial facilities near potential H₂S emission sources in Texas.
