|---|
| 8 | 8 | | AN ACT |
|---|
| 9 | 9 | | relating to establishment of maximum allowable ground level |
|---|
| 10 | 10 | | concentrations of hydrogen sulfide by the Texas Commission on |
|---|
| 11 | 11 | | Environmental Quality. |
|---|
| 12 | 12 | | BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS: |
|---|
| 13 | 13 | | SECTION 1. Subchapter B, Chapter 382, Health and Safety |

| 14 | 14 | | Code, is amended by adding Section 382.0217 to read as follows: |
|---|
| 15 | 15 | | Sec. 382.0217. MAXIMUM ALLOWABLE GROUND LEVEL |
|---|
| 16 | 16 | | CONCENTRATIONS OF HYDROGEN SULFIDE. (a) To protect public health, |
|---|
| 17 | 17 | | the commission shall: |
|---|
| 18 | 18 | | (1) by rule establish maximum allowable ground level |
|---|
| 19 | 19 | | concentrations of hydrogen sulfide; and |
|---|
| 20 | 20 | | (2) subject to Subsection (b), review the latest |
|---|
| 21 | 21 | | health studies regarding hydrogen sulfide emissions and reevaluate |
|---|
| 22 | 22 | | the maximum allowable concentrations at least once every five |
|---|
| 23 | 23 | | years. |
|---|
| 24 | 24 | | (b) In establishing the maximum allowable concentrations, |
|---|
| 25 | 25 | | the commission: |
|---|
| 26 | 26 | | (1) may establish different concentrations based on |
|---|
| 27 | 27 | | whether an area is used for residential, recreational, business, |
|---|
| 28 | 28 | | commercial, or agricultural purposes; and |
|---|
| 29 | 29 | | (2) may not allow any person to cause or allow |
|---|
| 30 | 30 | | emissions of hydrogen sulfide from a source or sources operated on a |
|---|
| 31 | 31 | | property or multiple sources operated on contiguous properties to |
|---|
| 32 | 32 | | exceed a net ground level concentration of: |
|---|
| 33 | 33 | | (A) 0.04 parts per million averaged over any |
|---|
| 34 | 34 | | 30-minute period if the downwind concentration of hydrogen sulfide |
|---|
| 35 | 35 | | affects a property used for residential, recreational, business, or |
|---|
| 36 | 36 | | commercial purposes; or |
|---|
| 37 | 37 | | (B) 0.06 parts per million averaged over any |
|---|
| 38 | 38 | | 30-minute period if the downwind concentration of hydrogen sulfide |
|---|
| 39 | 39 | | affects only property used for purposes other than residential, |
|---|
| 40 | 40 | | recreational, business, or commercial purposes. |
|---|
| 41 | 41 | | (c) The commission by rule shall classify a violation of the |
|---|
| 42 | 42 | | allowable ground level concentrations established by this section |
|---|
| 43 | 43 | | as having major significance under Section 5.754, Water Code. |
|---|
| 44 | 44 | | SECTION 2. Not later than September 1, 2026, the Texas |
|---|
| 45 | 45 | | Commission on Environmental Quality shall adopt rules required by |
|---|
| 46 | 46 | | Section 382.0217, Health and Safety Code, as added by this Act. |
|---|
| 47 | 47 | | SECTION 3. This Act takes effect September 1, 2025. |
