Texas SWPPP checklist for builders (2026)

Steps

1. Add up the ground you will disturb. 1 acre or more needs a plan, alone or in a bigger plan. Read do I need a SWPPP. (Parts I.A, I.B)
2. Find your role. Primary operator or secondary operator decides what you file. (Part I.B)
3. Look up your receiving water and your storm sewer operator. The plan names the waters, and the operator gets your copy. (Parts III.F.1(i), II.E.2(d))
4. Check what could stop you. Edwards Aquifer, oil and gas work, impaired water, and your city's rules. (Part II.C)
5. Write the SWP3 before you start. Site description, site map, controls with timing, maintenance, inspections. (Parts III.C, III.F)
6. Put silt fence or an equal control on the down-slope edges and show washout and vehicle exits on the map. (Parts III.F.2(c), III.F.1(g), VI)
7. Post the notice and send the copy. Small site: Form 20963 and a copy to the storm sewer operator, at least 2 days before. Large site: file the NOI online, send the copy and post Form 20961. (Parts II.E.2, II.E.3)
8. Install controls before soil disturbance begins. (Part III.C)
9. Inspect and fix. Every 14 days and within 24 hours of a 0.5-inch storm, or every 7 days. Report within 24 hours. Repair before the next rain if feasible. Revise the SWP3 within 7 days when an inspection calls for it. (Parts III.F.8, III.F.6)
10. Stabilize and close out. Reach final stabilization, remove the notice and send the copy within 30 days (large sites file a NOT). Keep records 3 years. (Parts II.F, VII)
