Free. No account, no email.
Key takeaways
- The permit says primary operators develop and implement the SWP3. It sets no license, engineer or certificate for the writer.
- The word "engineer" appears in the permit only in "good engineering practices".
- The person who signs must meet 30 TAC 305.44, such as a corporate officer, a general partner or the proprietor.
- No source we found settles whether writing a SWP3 is engineering. Some designs, like sediment basins, need an engineer's judgment.
What does the permit say about the writer?
The SWP3 must be developed and implemented by the primary operators of small and large construction activities.
The permit requires no professional engineer, license or certification to prepare a SWP3 or to inspect.
Who must sign?
Under 30 TAC 305.44(a), a corporation signs through a responsible corporate officer. A partnership or sole proprietorship signs through a general partner or the proprietor. A government signs through a principal executive officer or ranking elected person.
Reports can be signed by a duly authorized representative only with a written authorization that names a person or a position. Small operators use Form TCEQ-20403 and mail it.
A consultant can prepare a plan or an NOI, but the signing person must meet the signature rule.
What does engineering law say?
The Texas Engineering Practice Act includes "planning the use or alteration of land or water or the design or analysis of works or systems for the use or alteration of land or water" in the practice of engineering. No one may practice engineering without a license.
The Texas Board of Professional Engineers and Land Surveyors has issued no policy opinion on SWPPPs. A request for one (PAO 27) was withdrawn on Nov 19, 2009.
Whether writing a SWP3 is engineering is not decided by any source we found.
Which parts of a plan may need an engineer?
ReadySWPPP does not build plans for work that needs engineering design: a sediment basin where 10 or more acres drain to one point, and sites in the Edwards Aquifer program.
Other items can need engineering judgment, such as permanent stormwater controls and outfall channel design.
Where do cities ask for an engineer?
- Austin: a 2017 proposed rule called for an erosion plan signed by a Texas engineer or a CPESC. We could not confirm the current text. Check with the city.
- San Antonio: a secondary source says a licensed Texas engineer must sign the SWPPP. We could not confirm it. Check with the city.
- Houston: the separate post-construction permit uses an engineer-sealed plan.
See the city guides.
