| Field | VT Vermont |
|---|---|
| NPDES Program | State-Delegated |
| Permitting Agency | Vermont Department of Environmental Conservation (DEC) |
| Permit Name | Construction General Permit 3-9020 (CGP 3-9020) — Vermont's Construction Stormwater General Permit; Vermont operates under its own state water quality permit program (not branded as NPDES, but functionally equivalent and EPA-authorized) |
| Construction Threshold | ≥ 1 acre of land disturbance (or < 1 acre if part of a larger common plan of development or sale that will ultimately disturb ≥ 1 acre); Vermont also regulates stormwater from smaller sites through its municipal stormwater program and Act 250 land use review process; sites disturbing ≥ 1 acre in regulated watersheds may face additional requirements under the Vermont Stormwater Management Rule |
| NOI Lead Time | A complete Notice of Intent (NOI) or permit application must be submitted to Vermont DEC Stormwater Program and approved before construction begins; Vermont recommends submitting the NOI at least 14 days before the planned construction start date to allow for DEC review and processing; no construction may begin until written permit authorization is received from DEC |
| Application Method | Online via Vermont's eDEC electronic permitting system (available at dec.vermont.gov/permits); paper applications are also accepted; the eDEC portal is the preferred method; some permit types may still require supplemental paper documentation |
| Permit Fee | One-time permit application fee based on disturbed acreage: 1 to < 5 acres: $362; 5 to < 10 acres: $720; 10 to < 25 acres: $1,080; 25 to < 50 acres: $1,440; ≥ 50 acres: $1,800; fees are set under Vermont's environmental permit fee schedule and subject to periodic legislative adjustment — verify current amounts with Vermont DEC |
| SWPPP Required | Yes |
| PE Certification Required | Yes |
| SWPPP Template Available | Yes |
| Inspection Frequency | At least once every 7 calendar days during active construction and within 24 hours after any storm event producing ≥ 0.5 inches of precipitation in a 24-hour period; during winter months or periods of frozen ground, inspection frequency may be modified per DEC guidance; when the site is temporarily stabilized, inspections may be reduced to monthly |
| Inspector Qualification | Vermont requires inspections to be performed by or under the supervision of a Vermont-licensed Site Technician (LST) or Professional Engineer (PE); the Licensed Site Technician certification is a Vermont-specific credential administered through the Vermont DEC; this is one of the most stringent inspector qualification requirements of any state construction stormwater program |
| Post-Construction Required | Yes |
| Turbidity Standard | No universal numeric NTU turbidity effluent limit in CGP 3-9020; narrative water quality standards apply; however, Vermont's water quality standards include specific turbidity criteria for certain classified waters |
