Permitting AgencyVermont Department of Environmental Conservation (DEC)
Permit NameConstruction 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 TimeA 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 MethodOnline 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 FeeOne-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 RequiredYes
PE Certification RequiredYes
SWPPP Template AvailableYes
Inspection FrequencyAt 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 QualificationVermont 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 RequiredYes
Turbidity StandardNo 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
