Who may prepare a stormwater plan in Missouri

We have not confirmed this jurisdiction against a primary source. Rather than show you a plausible answer, this page tells you that, and where to get the real one.

The answer

Not verified

Not verified for Missouri, confirm with the Missouri permitting authority. We hold no primary source confirming whether a credentialed preparer is required here. An absence of evidence is not evidence that anyone may prepare the plan, and we will not present it as one.

What this means for a generated plan

Where a credential applies, or where we cannot confirm that none does, treat a generated document as a complete draft for a credentialed preparer to review, amend and sign. It is not by itself a compliant filed plan, and ours says so on its face.

State*

Activity*

Total acres disturbed*

Total land disturbance over the whole project, including staging and access. This decides whether you need a permit at all.

Acres open at any one time

Optional. If you phase the work, the most that will be disturbed at once. Leave blank if the whole site is open together. The stabilisation deadline turns on this figure, not the total.

Part of a larger common plan of development or sale

A half acre lot inside a 40 acre subdivision is covered even though the lot alone is under the threshold. This is the most commonly missed trigger in the permit.

Receiving water and site conditions(optional, but they change the inspection frequency)

Discharges to a sediment or nutrient impaired water

Discharges to a Tier 2, 2.5 or 3 water

Arid, semi arid or drought stricken area

May allow a reduced inspection frequency during the seasonally dry period.

In Indian country

EPA keeps permitting authority in Indian country even inside a state that runs its own programme.

No account, no card, nothing transmitted.

What people ask about preparing a SWPPP in Missouri

Do I need a qualified preparer for a SWPPP in Missouri?

We have not confirmed whether Missouri requires a credentialed preparer. Confirm with the Missouri permitting authority before relying on a plan prepared in house or generated by a tool. We will not assume the permissive answer, because assuming it is how an invalid plan gets filed.

Does a professional engineer have to stamp the plan in Missouri?

Practice act citations are routinely overstated on this point. A PE stamp is not required as a general matter in most states with no preparer gate, and where we have not verified it we will not assert either answer. Confirm with the state board or the permitting authority.
