Can my site superintendent sign it?

Only if they fall inside the signatory categories, or hold a written authorisation that does. Check Appendix G, Part G.11 rather than assuming.

Does an electronic signature count?

Read the permit's own signature clause. This is exactly the kind of detail where a generated answer would not be worth the paper.

Who signs a SWPPP?

The operator's signatory signs and dates the plan, and who may sign — or be authorised to sign on their behalf — is defined in Appendix G, Part G.11 of the federal permit, which SwpppDraft has not verified against the current text.

A signature from the wrong person is a defect in the plan

Part 7.2.10 requires the operator's signatory to sign and date the SWPPP in accordance with Appendix G, Part G.11. Read the categories there rather than from any page including this one — we have not re-verified that appendix, and it is not a detail worth taking second-hand.

This is a different question from who may *prepare* the plan. A state can allow the operator to write it and still require a corporate officer at a particular level to sign it.

Record modifications too

The date of every later modification, and who authorised it, goes on the signature page or in the modification log (Part 7.4.2–7.4.3).

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.
