Relating to a groundwater study of certain aquifers underlying the territory of the Neches and Trinity Valleys Groundwater Conservation District by the Texas Water Development Board before the issuance of permits or permit amendments by the district.

SB 50 requires the Texas Water Development Board to study sustainable groundwater production in aquifers under the Neches and Trinity Valleys Groundwater Conservation District. The study must analyze long-term groundwater availability, compare it to existing models, and assess hydrological impacts of proposed production and transfers. The bill imposes a permit moratorium: the district cannot issue new groundwater permits or amendments until 270 days after the study report is submitted (due January 12, 2027). This directly affects the district and applicants seeking groundwater permits or amendments for production and transfer outside the district. The law expires November 1, 2027.
