What ReadySWPPP does not cover

What are the cases?

1. Sediment basins. Where 10 or more disturbed acres drain to one point at one time, the permit calls for a sediment basin where feasible, sized by calculation. That needs engineering design.
2. Edwards Aquifer. Sites in or near the Edwards Aquifer program zones. Recharge zone at any size, and contributing zone at 5 acres or more: TCEQ must sign off on the Edwards plan before soil is disturbed. Parts of Bexar, Comal, Kinney, Medina, Uvalde, Hays, Travis and Williamson counties are in the program.
3. Oil and gas. Construction for oil and gas exploration, production, processing, treatment or transmission is not under TXR150000. Administrative buildings, parking lots and the roads that serve an administrative building at those sites still are.
4. Impaired water. The permit does not authorize a new discharge of the listed pollutant to an impaired water unless state rules allow it, and where a cleanup plan (TMDL) exists your SWP3 must follow it. We do not build plans where the water is impaired for sediment, turbidity or siltation.
5. Linear projects, such as pipelines and long utility runs. Planned for a later version.
6. Batch plants on site (Part V of the permit). Planned for a later version.
7. Other exclusions. Oil and gas sites are listed above. Also not covered: TxDOT contracts, Indian Country land, places where 30 TAC 311 watersheds prohibit coverage, and nuclear waste storage facilities.
8. City rules beyond the state permit. We list the city rules we verified. A 2017 Austin proposed rule called for an erosion plan signed by an engineer or a CPESC. We could not confirm San Antonio's rule. Everywhere else, check with your storm sewer operator.
9. Design of permanent (post-construction) controls. We list what your engineer designed.
10. Filing the NOI. We prepare every answer and the walkthrough. TCEQ's page (read Nov 13 2026) says each CGP NOI is now reviewed by staff before it is authorized, with no provisional coverage, under a Governor's directive dated Sept. 21, 2026.
11. Points in water. If the pin for your address lands in water, the check gives no answer for it. Move the pin to the site.

Why do these limits exist?

The permit says a plan alone is not enough in these cases, or the case needs work that a software plan cannot do. You prepare and sign the plan. We never claim TCEQ sign-off or engineering.

What if my site is in a place you did not research?

For cities we did not research, we do not know their extra rules. We say so, and we never imply the state plan is all you need.
