What triggers it: Plan scope rather than acreage: Only where the plan includes the Stormwater Management Practice component.

Credentials that qualify

Licensed PE
Registered landscape architect
Qualified Professional (licensed Professional Engineer, Registered Landscape Architect or other NYSDEC endorsed individual); a New York licensed PE is required for components involving the practice of engineering

New York gates only when the stormwater management practice component is required. An erosion-control-only plan is not gated. An erosion-and-sediment-control-only plan has NO preparer credential requirement. The 4-hour NYSDEC training qualifies a person only under the direct supervision of a licensed PE or RLA. Reconciled against the jurisdiction registry, which found a preparer requirement this entry had missed. Where the two sources disagreed we kept the stricter answer.

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.

Does a professional engineer have to stamp the plan in New York?
