House Bill No. 1341 aims to enhance public health protections by establishing maximum allowable ground level concentrations of hydrogen sulfide through the Texas Commission on Environmental Quality (TCEQ). The bill introduces a new section, 382.0217, to the Health and Safety Code, which mandates the TCEQ to create rules that set these maximum concentrations. The commission is required to review the latest health studies on hydrogen sulfide emissions and reevaluate the allowable concentrations at least once every five years. The bill also allows the commission to set different concentration limits based on land use, such as residential, recreational, business, or agricultural purposes.

Additionally, the bill specifies that emissions of hydrogen sulfide must not exceed 0.04 parts per million averaged over a 30-minute period if they affect properties used for residential or similar purposes, and 0.06 parts per million for other types of properties. Violations of these established concentrations will be classified as having major significance under the Water Code. The TCEQ is required to adopt the necessary rules by September 1, 2026, and the act will take effect on September 1, 2025.
