What's next

These dates come from the tracker. Texas Data Center Watch has no recorded upcoming Tom Green County hearings or votes on data centers.

Statewide permit pause: Under the Governor's Sept. 21 order halting permits sought by data centers (Governor's office), TCEQ sent its Oct. 19 compliance letter: it says permits for infrastructure directly supporting data centers are paused, pending applications are being screened, and claimed authorizations are suspended where possible (TCEQ letter). The Texas Tribune reported Oct. 20 that TCEQ says stormwater permits flagged by Public Citizen were suspended (Texas Tribune). On Oct. 21 TCEQ posted that its STEERS e-filing system for automatic authorizations is temporarily shut down so staff can check whether applications relate to data centers (TCEQ STEERS notice); the Texas Tribune reports a spokesman said applications must be physically provided (Texas Tribune, Oct. 21). The tracker doesn't show whether any project in Tom Green County has a pending TCEQ permit.
