H.B. No. 5675 proposes amendments to the governance structure and powers of the Presidio County Underground Water Conservation District. The bill increases the board of directors from five to seven members, with specific provisions for appointments: one member will be appointed by the governing body of the City of Marfa, and another by the governing body of the City of Presidio. Additionally, the bill clarifies that vacancies on the board will be filled in the same manner as the original appointments, rather than by the commissioners court of Presidio County, which is no longer mentioned in the context of filling vacancies.

The bill also updates the language regarding the district's powers, replacing "underground water conservation" with "groundwater conservation" and changing the overseeing authority from the Texas Water Commission to the Texas Commission on Environmental Quality. Furthermore, it specifies that Section 36.121 of the Water Code does not apply to the district. The legal notice for the introduction of this Act has been published, and it will take effect immediately upon receiving a two-thirds vote from both houses or on September 1, 2025, if that threshold is not met.
