The stormwater permit for construction in Texas
Texas runs its own NPDES programme, so a state issued construction general permit governs. Below is what our engine can say about it, and where we have not read that permit, what it will not say.
Governing permit
TPDES Construction General Permit (2023 CGP), TXR150000

Who may prepare the plan
No preparer credential foundNo preparer credential was found for Texas. On what we have verified, a generated plan can be adopted by the operator without a credentialed signature. Local ordinances can still be stricter than state law.
OKR10-style confirmation not needed; no preparer credential mandated
No permit section cited. Confirm this with your permitting authority.
Does a site in Texas need coverage
Worked for a one acre site as a reference point. Change the acreage in the tool below and the answer, and its reasoning, change with it.
Coverage
Permit coverage required
The project disturbs 1 acres, at or above the 1 acre threshold, so it needs permit coverage.

Read these before you act on the answer
- Requirements below are what we have read and cited directly from TPDES Construction General Permit (2023 CGP), TXR150000, not the federal CGP. A category we have not yet transcribed from this permit is omitted here rather than assumed to match EPA's rule.
- The permit body's numeric benchmarks (Part IV, Section A) apply only to storm water discharges from concrete batch plants supporting a construction site, not to general construction-site storm water discharge itself; Texas's general permit does not impose numeric effluent limits/benchmarks (turbidity, pH, etc.) on ordinary construction runoff. No numeric buffer/setback distance from surface waters was found in the general permit body — it requires only generic 'vegetative buffer strips or equivalent sediment controls' at down-slope boundaries (Part III.F.3.(c)(i)(B)) without a specified footage, and separately cross-references TCEQ's Edwards Aquifer rule (30 TAC Chapter 213) for aquifer-zone sites without stating that rule's specific distance requirements in this document. Final stabilization completion is tied to permit termination (Part III.F.2.(b)(iv)) rather than to a fixed number of days after initiation as in some other permits — only the *initiation* deadline (14 days) is a fixed number. The permit PDF's own cover page did not yield machine-extractable effective/expiration date text (likely image-rendered), so those two dates are sourced instead to verbatim quotes fetched from TCEQ's official construction-stormwater webpage rather than the PDF body. Fee amounts (Part VIII) were not reviewed.
- No preparer credential was found for Texas. On what we have verified, a generated plan can be adopted by the operator without a credentialed signature. Local ordinances can still be stricter than state law.
- Basinwise does not perform the physical site inspections the permit requires. Those must be carried out on site by a qualified person.
How this answer was reached, step by step
- 1
Coverage threshold
The project disturbs 1 acres, at or above the 1 acre threshold, so it needs permit coverage.
- 2
Permitting authority
Texas. The state runs its own programme under TXR150000.
- 3
Preparer credential
No preparer credential was found for Texas. On what we have verified, a generated plan can be adopted by the operator without a credentialed signature. Local ordinances can still be stricter than state law.
What to do next
- 1. Confirm the governing permit. Read TPDES Construction General Permit (2023 CGP), TXR150000 directly. It is linked above, and it is the document an inspector will hold you to. Texas Commission on Environmental Quality (TCEQ)
- 2. Settle the preparer question before you draft. Getting this wrong costs a redraft at best. The detail is on the credential page for this state. Preparer credential in Texas
- 3. Screen the site. Run the real acreage and receiving water facts through the tool below. You get the inspection frequency, the stabilisation deadlines and the filing path with the permit section behind each.

What people ask about the Texas construction stormwater permit
Do I need a stormwater permit for a construction site in Texas?
Permit coverage is triggered at one acre of land disturbance, and below one acre if the project is part of a larger common plan of development or sale that will ultimately disturb an acre or more. The project disturbs 1 acres, at or above the 1 acre threshold, so it needs permit coverage.
Who issues the construction stormwater permit in Texas?
Texas Commission on Environmental Quality (TCEQ) issues TPDES Construction General Permit (2023 CGP), TXR150000.
Does Texas require a qualified preparer for the plan?
No preparer credential was found for Texas. On what we have verified, a generated plan can be adopted by the operator without a credentialed signature. Local ordinances can still be stricter than state law.
