Alabama SWPPP requirements (2026)
Can I write my own SWPPP in Alabama?
Alabama requires the SWPPP to be prepared by a licensed professional. This tool is not usable in Alabama. Basis: NPDES CGP ALR100000 (effective 2026-04-01), Part III.F.1–2 and Part V definitions.
Who may prepare the plan in Alabama
construction activity may not commence until a CBMPP has been prepared in a format acceptable to the Department and certified by a QCP… Qualified Credentialed Professional or QCP means a qualified erosion control specialist such as licensed… professional engineer (PE)… a Certified Professional in Erosion and Sediment Control (CPESC)… or a Certified Designer of Sediment and Erosion Control (CDSEC)
Our reading of NPDES CGP ALR100000 (effective 2026-04-01), Part III.F.1–2 and Part V definitions:Alabama requires the construction best-management-practice plan to be certified by a Qualified Credentialed Professional, and every route to that credential starts from a professional licence or certification.
How Alabama differs from the federal baseline
States with no NPDES authorisation of their own run on the EPA 2022 Construction General Permit, whose "qualified person" definition is a knowledge and skill threshold that the operator's own staff can meet — it names no licence. Alabama goes further than that baseline: it names a credential, and the operator's own familiarity with the permit does not satisfy it.
Federal baseline: EPA 2022 CGP (no state NPDES authorisation), Appendix A definitions.
What that means for a 1–5 acre site
Below one disturbed acre, federal construction general permit coverage is usually not required at all unless the site is part of a larger common plan of development. Check whether you need a SWPPP before you pay for one.
Above five disturbed acres you are outside the 1–5 acre range this tool was built for. Several states change their preparer requirements above five acres, so re-read your state permit before relying on a self-prepared plan.
County and city rules are not covered here. This page answers the state-level question only; a local authority can require more, and that is for you to check.
Alabama SWPPP questions
- Can I write my own SWPPP in Alabama?
- Alabama requires the SWPPP to be prepared by a licensed professional. This tool is not usable in Alabama.
- Which credentials does Alabama accept on a SWPPP?
- Alabama requires the construction best-management-practice plan to be certified by a Qualified Credentialed Professional, and every route to that credential starts from a professional licence or certification. The clause is NPDES CGP ALR100000 (effective 2026-04-01), Part III.F.1–2 and Part V definitions, read on 2026-08-03.
- Which acreage counts — the whole site or the disturbed part?
- Disturbed area is what these clauses measure, and it is what the questionnaire asks for — a 40-acre parcel with 1.5 disturbed acres is a 1.5-acre project for this purpose. Total site area is asked for separately and does not decide the answer.
- Does Alabama run its own permit, or the federal one?
- On its own. Alabama issues the construction general permit or implementing regulation this page was read from — NPDES CGP ALR100000 (effective 2026-04-01), Part III.F.1–2 and Part V definitions. The federal permit still sets what a SWPPP has to contain; the state document is what decides who may write it here.
- What does a SWPPP cost in Alabama?
- A consultant-prepared SWPPP for a small site is commonly quoted at around $497 — a market figure inherited from our own competitor review, which we have not re-verified. In Alabama that cost is not optional: the permit requires a credentialed preparer, so there is no self-prepared route to weigh it against, and SwpppDraft cannot serve Alabama at any price.
- Do county or city rules apply on top of this?
- They can, and this page does not cover them. The scan behind it answered the state-level question only, so a county or municipality in Alabama may require more — a stamped plan, a local permit, or a different form — even where the state permit does not. Ask the authority that will receive your paperwork before you write the plan, not after.
- Who should I go to in Alabama instead?
- Contact a professional licensed in that state (a professional engineer, or the credential the permit names) to prepare and seal the plan. We do not offer that service and we do not refer or take a commission.
- Is there anything else to know about Alabama?
- Alabama's permit PDF has no text layer; the quoted wording was recovered by OCR (Ghostscript and Tesseract, two independent passes agreeing) rather than copied from selectable text. Re-verify by the same method.

What we are, and what stays your responsibility
- 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.
- 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.
- 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.
- 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.
- 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.
