Tarrant County well proposals: four paperwork changes to review before the October 27 hearing
Northern Trinity proposes a lower hydrogeologic-report threshold, subdivision sequencing, a conditional utility audit requirement and driller information changes. The hearing is October 27 at 2 p.m.; these are proposed rules, not adopted requirements.

Tarrant County / Northern Trinity district
Could a planned well, larger pumping request or subdivision need more paperwork before approval?
- Who it matters to
- Water suppliers planning more groundwater production, groundwater-dependent subdivision developers, drillers and permit applicants in the Northern Trinity Groundwater Conservation District. Neighbors and other interested people may also comment.
- What changed
- The October 27 rulemaking hearing concerns proposed changes to well and permit applications, hydrogeologic reports and other rules. Four selected changes below could affect project planning; none is described here as an adopted requirement.
- Status at source check
- Proposed, not adopted at the October 20 source check. The notice allows adoption at the end of the hearing or later, including changes based on comments without another notice.
- Next date or action to check
- Review the redline sections relevant to your project and present verbal or written comments at the public hearing October 27, 2026, at 2 p.m. Central, at the district office, 1100 Circle Drive, Fort Worth, TX 76119. Call 817-249-2062 for hearing information; the notice asks for accommodation requests at least 24 hours in advance. Afterward, check for the adopted wording and effective date before relying on the proposal.
1. A lower threshold for a hydrogeologic report
Proposed Rule 5.10 would lower the annual production threshold from 50,000,000 to 9,124,416 gallons for covered permit applications, including requests to increase production to that level. The redline also changes related aggregation language for multiple wells under common ownership or operation within one-quarter mile. This does not mean every private well would need a study; application type, exemptions, production and the multiwell provisions matter.
2. Subdivision plat approval before most well applications
Proposed Rule 3.11 would generally prevent the district from accepting, reviewing or approving well registration or permit applications for a subdivision requiring groundwater availability certification until the plat is approved. It provides an exception for wells specifically needed to complete that certification study. Developers should check the sequence with the platting authority and district before planning the well application.
3. A water-loss audit for a defined utility expansion request
Proposed Rule 5.3(a)(14) would require the most recently required water-loss audit when the applicant is a retail public utility already legally required to submit an annual audit to the Texas Water Development Board and seeks increased authorized annual groundwater production for an existing system through an operating permit or amendment. All of those conditions matter; this is not a general audit requirement for every well owner.
4. Identify the driller, or state that one has not been chosen
The proposed application provisions call for the expected driller’s name and Texas license number, or a statement that the driller is not yet determined. Proposed Rule 3.12 covers new-well registration, changes of driller and the later-selection process; Rule 5.3(a)(11) adds driller information to permit applications. When an application is approved without a driller identified, the applicant would notify the district once one is selected, and the driller must sign and complete the applicable application information before drilling.
The hearing covers more than these four changes
The notice also lists spacing, dewatering, metering, well systems, repeated production above permitted amounts and other enforcement and conforming amendments. Read the complete redline for your situation. A pumping request, permit approval and actual pumping remain different things; this proposal does not establish that a nearby well will fail.

What remains unknown
- The sources checked do not establish final adopted wording, an effective date or a hearing outcome. The board may change the proposal after comments.
- These are selected changes, not a complete analysis of every proposed amendment or a determination of how the district would classify a particular project. No claim is made that the proposed activities are already prohibited.
