Groundwater Conservation Districts

The Groundwater Planning and Assessment team processes, reviews, and facilitates landowner petitions for creating Groundwater Conservation Districts (GCDs) and evaluates filed legislative bills that create new or modify existing GCDs. The TCEQ creates GCDs within Priority Groundwater Management Areas (PGMAs). The team processes and coordinates limited oversight of GCDs relating to groundwater management plans and joint-district planning within Groundwater Management Areas (GMAs), providing educational and technical assistance upon request.

TCEQ Groundwater Conservation District Performance Review

In accordance with the Texas Water Code Sections 36.301 - 36.303, the TCEQ is responsible for Groundwater Conservation District (GCD) performance review and action if:

• a GCD management plan is not adopted, readopted, or submitted to the Executive Administrator of the Texas Water Development Board (TWDB) within statutory deadlines (Note: this is by far the most common violation);
• the Executive Administrator of the TWDB denies approval of a submitted management plan and the GCD does not address and obtain management plan approval within statutory deadlines or has exhausted all appeals of the denial;
• the State Auditor determines that a GCD is not operational; or,
• a petition requesting a TCEQ inquiry of a GCD has been accepted and a review panel has submitted a report and recommendation to TCEQ.
