The stormwater permit for construction in New York
New York runs its own NPDES programme, so a state issued construction general permit governs. Below is what our engine can say about it, and where we have not read that permit, what it will not say.
Governing permit
SPDES Construction General Permit (CGP) GP-0-25-001 for Stormwater Discharges from Construction Activities
- Issued by
- New York State Department of Environmental Conservation (NYSDEC)
- Permit number
- GP-0-25-001
- Version determined against
- as published by the state agency
Who may prepare the plan
Conditional, depends on the siteNew York gates plan preparation conditionally. The gate is triggered by plan scope rather than acreage: Only where the plan includes the Stormwater Management Practice component. Confirm which case applies to your plan before relying on a generated document.
Qualifying routes
- 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.
