Relating to the issuance by the Texas Commission on Environmental Quality of permits for certain wastewater treatment facilities.

HB 3252 requires the Texas Commission on Environmental Quality to deny permits for small pre-manufactured wastewater treatment facilities (under 500,000 gallons/day) located within 1,000 feet of municipal wastewater lines. It mandates applicants prove they will implement weatherproofing/security measures and provide financial assurance for future maintenance. The law applies only to new permit applications filed on or after September 1, 2025. This directly affects developers and operators seeking to build or upgrade small-scale wastewater treatment systems in Texas.
