Checked October 20, 2026 against the permit text published by Oklahoma Department of Environmental Quality. Sources and sections are listed at the end of this page.
In Oklahoma, construction stormwater coverage comes from General Permit OKR10 for Stormwater Discharges from Construction Activities (permit no. OKR10), issued by Oklahoma Department of Environmental Quality (DEQ). It took effect October 18, 2022 (modified April 1, 2023 and November 1, 2023); no expiry date is printed on the modified permit we read, and it continues administratively if not reissued (Part 7.2).
Scope note. Engineering parts of the SWP3, such as sediment basin design, must come from your licensed professional engineer (Part 5.1.B).

- Update the SWP3 within 7 calendar days of changes (Part 3).

What a SWPPP Desk plan covers here
We prepare a site-specific plan written to OKR10, with each section mapped to the permit part it answers. You, the operator, review and sign it and keep it on site.
Checkout open in Oklahoma. State ruling: Sell. The site check on the plan page applies these conditions before payment. See coverage.
What we do not do
- Our plans are not sealed or stamped. BMPs that need design calculations, such as sediment basins and post-construction practices, come from your design professional.
- The operator signs the plan and is responsible for it.
- We do not visit or inspect sites.
- We do not file the NOI or any permit application for you. We tell you which form and portal the permit names.
