Relating to certain procedures for civil suits brought by local governments or certain other persons for violations of certain laws under the jurisdiction of, or rules adopted or orders or permits issued by, the Texas Commission on Environmental Quality.

HB 736 amends Texas Water Code Section 7.3511 to change procedures for lawsuits about environmental violations under the Texas Commission on Environmental Quality (TCEQ). It delays when local governments or affected individuals can file civil suits after TCEQ receives a violation notice - requiring them to wait until after TCEQ or the Attorney General has begun enforcement within 90 days of notice. The bill repeals the existing subsection (e) and takes effect September 1, 2025. This directly affects local governments, residents, and legal representatives seeking to sue for TCEQ-regulated environmental violations.
