The following action adds a new rider that directs the TCEQ to assess current emissions and current ambient air quality standards, and consider adopting rules to better protect public health and the environment.

On page VI-29 of the Texas Commission on Environmental Quality's bill pattern, add the following new rider:

____.  Hydrogen Sulfide Assessment. Out of existing funds, the commission will conduct an assessment of emissions and ground level concentrations of hydrogen sulfide emissions. The assessment should include the following information:

Current maximum allowable ground level concentrations of hydrogen sulfide authorized by state rule;

A list of existing commission monitoring stations that monitor for hydrogen sulfide concentrations;

Data on the findings from those monitoring stations in terms of ground level concentrations of hydrogen sulfide;

Emissions data on hydrogen sulfide from regulated industries;

Any identified gaps in monitoring stations where the commission believes additional monitoring would be helpful to identify maximum concentrations of hydrogen sulfide;

A review of any relevant state or national health studies conducted within the last 10 years indicating the impacts of hydrogen sulfide on public health and whether the current maximum ground level concentrations in Texas are protective of public health;

Information on any enforcement actions taken against regulated industries due to high levels of ground level concentrations of hydrogen sulfide or unauthorized emissions of hydrogen sulfide;

A review of how other states have established maximum concentrations of ground level hydrogen sulfide concentrations; and

Any recommendations on potential changes in the current maximum concentrations of hydrogen sulfide to better protect public health.

The TCEQ shall provide a copy of its assessment to the Legislative Budget Board as well as to the relevant committees of the legislature no later than September 1 of 2026. Nothing in this assessment prevents the TCEQ from considering rulemaking or enforcement efforts on emissions of hydrogen sulfide either before or after the finalization of the assessment.
