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.

What people ask about preparing a SWPPP in Michigan

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

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