Write your own SWPPP for a 1–5 acre site

Can the operator of a 1–5 acre construction site in Texas write the SWP3 themselves?

Yes. Under TPDES general permit TXR150000 (effective 2023-03-05) Part III.F, the SWP3 must be developed and implemented by the primary operator; the permit text contains no PE, CPESC, or other licensing requirement for preparing the plan.

You disturbed more than an acre, the permit office wants a stormwater pollution prevention plan, and work starts in days. The free templates are empty skeletons. A consultant is around $497 and a day of waiting. In 40 states the law lets you write the plan yourself — five of those only once your site conditions are checked, and two only after you take an open-enrolment course. SwpppDraft is built to be the fast way through that, with the responsibility staying where the permit already puts it: with you.

What you would get

A filled-in plan, not a blank template

You answer a questionnaire about the site — operator, address, acreage, slope and soils, the water you drain to, your construction phases, the controls you plan to use. Every question is something you can answer from the drawings in front of you. Nothing asks you to make an engineering judgement.

Federal baseline plus your state's clauses

The structure follows EPA's 2022 Construction General Permit; your state's additional requirements are written in with their clause numbers, so a reviewer can check any statement against the permit it came from.

A straight answer about your state

Nine states require a licensed professional, one publishes nothing we could verify, five depend on your site conditions, and two want you to take an open-enrolment course first. We tell you which one you are in before you spend anything.

What it will not do

First question: does your state let you write it yourself?

Nine states require a licensed professional to prepare or seal the plan, and one more publishes no rules we could read. In those, no tool can help you and we say so instead of taking your money. Pick your state to see the answer and the clause it comes from.

Every answer here comes from that state's current construction general permit, read on 2026-08-03. See all 50 states in one table.

What it will cost

Two tiers, one payment, no subscription. A consultant-prepared SWPPP runs about $497 and takes a day; this is the self-prepared side of that trade — cheaper and immediate, with the responsibility staying with you.

What we are, and what stays your responsibility

  1. SwpppDraft is a document generation tool. It does not provide engineering services, legal services, or compliance consulting, and no engineer or attorney reviews what it produces.
  2. Everything in the document is built from the site facts you enter. Checking that those facts are right, and that the resulting plan fits your project, is yours to do.
  3. We do not file anything on your behalf, we do not certify or endorse your compliance, and we accept no liability for what happens when you use the document.
  4. State-level requirements carry the date we verified them. County and city rules are not covered — some local jurisdictions require a licensed preparer even where the state does not, and you have to check that yourself.
  5. When the product opens, our total liability will be capped at the amount you paid us. Today that amount is zero, because nothing is for sale.
