  89R4563 CMO-D     By: Reynolds H.B. No. 1341       A BILL TO BE ENTITLED   AN ACT   relating to establishment of maximum allowable ground level   concentrations of hydrogen sulfide by the Texas Commission on   Environmental Quality.          BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS:          SECTION 1.  Subchapter B, Chapter 382, Health and Safety   Code, is amended by adding Section 382.0217 to read as follows:           Sec.   382.0217.     MAXIMUM ALLOWABLE GROUND LEVEL   CONCENTRATIONS OF HYDROGEN SULFIDE. (a) To protect public health,   the commission shall:                 (1)     by rule establish maximum allowable ground level   concentrations of hydrogen sulfide; and                 (2)     subject to Subsection (b), review the latest   health studies regarding hydrogen sulfide emissions and reevaluate   the maximum allowable concentrations at least once every five   years.           (b)     In establishing the maximum allowable concentrations,   the commission:                 (1)     may establish different concentrations based on   whether an area is used for residential, recreational, business,   commercial, or agricultural purposes; and                 (2)     may not allow any person to cause or allow   emissions of hydrogen sulfide from a source or sources operated on a   property or multiple sources operated on contiguous properties to   exceed a net ground level concentration of:                       (A)     0.04 parts per million averaged over any   30-minute period if the downwind concentration of hydrogen sulfide   affects a property used for residential, recreational, business, or   commercial purposes; or                       (B)     0.06 parts per million averaged over any   30-minute period if the downwind concentration of hydrogen sulfide   affects only property used for purposes other than residential,   recreational, business, or commercial purposes.           (c)     The commission by rule shall classify a violation of the   allowable ground level concentrations established by this section   as having major significance under Section 5.754, Water Code.          SECTION 2.  Not later than September 1, 2026, the Texas   Commission on Environmental Quality shall adopt rules required by   Section 382.0217, Health and Safety Code, as added by this Act.          SECTION 3.  This Act takes effect September 1, 2025.
