Summary
TCEQ is proposing or advancing amendments to the aquaculture (TXG130000), concrete-batch (TXG110000) and pesticides (TXG870000) general permits. The aquaculture amendment would allow oyster-mariculture cleaning over state waters; the concrete-batch renewal clarifies SWIP and monitoring requirements; the pesticides draft aligns with EPA and will open for public comment Feb. 23, 2026.
Several sector-specific general-permit renewals and amendments are advancing at the Texas Commission on Environmental Quality.
Mike Aplin said TCEQ is proposing amendments to the aquaculture general permit TXG130000 to allow cleaning of oyster-mariculture structures over state waters and to revise the definition of wastewater to include washdown and processing water. The draft package was reviewed by EPA and received an approval letter dated May 27, 2025; no public comments were received and the amended permit is scheduled for adoption at the commissioners’ agenda on Feb. 11, 2026.
On the concrete-batch permit (TXG110000), Aplin and other staff said TCEQ plans proposal notices in March. Proposed changes include updated representative monitoring, clarified requirements for stormwater pollution prevention plans (SWIP), a requirement that point-of-discharge locations include longitude/latitude on site maps, expanded training expectations for facility personnel, and a timeline to remedy nonconformances (actions to be completed within 12 weeks after an annual compliance inspection report identifies them).
Brian Saran briefed the group on the pesticides general permit (TXG870000), which TCEQ is renewing and amending for consistency with EPA’s pesticide general permit. Proposed changes require Level 1A operators to document visual evaluations of treatment areas, maintain pre- and post-application records and sign a pesticides discharge management plan. Notice was scheduled to publish Jan. 23, 2026, and TCEQ plans a public meeting and end of comment period on Feb. 23, 2026.
TCEQ staff said proposal documents and commission-integrated-database materials are available for proposed permits, and that staff will post adoption materials and response-to-comments documents as those processes conclude.
