Vermont Construction Storm Water Permit (6-VT-b)

In Vermont, a developer may need a Vermont General Permit 3-9020 for Stormwater Runoff from Construction Sites (Construction General Permit) from the Department of Environmental Conservation (DEC), a department within the Agency of Natural Resources (ANR), for stormwater discharges from construction activities that result in a total land disturbance of equal to or greater than one acre or that are part of a larger common plan of development that will disturb one or more acres, where those discharges enter state waters or a conveyance leading to state waters. 10 V.S.A. § 1264(d)(1)(D); NPDES Stormwater General Permits for Construction Guidelines; Construction General Permit; 10 V.S.A. § 1264(c)(4. The DEC issues NPDES permits for all proposed non-federal projects in Vermont. 10 V.S.A. § 1258(b). Projects that disturb less than one acre of land generally do not need a permit, but the DEC may still require a developer to obtain a Construction General Permit if the Secretary of the ANR determines that the project may contribute to a violation of a water quality standard, contribute pollutants to surface waters of the state, or exceed wasteload allocations (“total maximum daily loads”). Construction General Permit § 1.4(A)(2); 40 CFR 122.26(a)(1)(v),(b)(15)(ii); See generally Construction General Permit.


Construction Storm Water Permit Process

6-VT-b.1 — Complete Project Risk Evaluation

Prior to applying for permit coverage, the developer should complete a Project Risk Evaluation in order to determine if the proposed construction activities constitute: Low Risk, Moderate Risk, or whether an Individual permit is required. Determining the risk level of the proposed construction activity defines the application and permit requirements for the developer’s project.

The Project Risk Evaluation will determine a number of key risk and mitigation factors about the developer’s project, including whether the construction activities are within impaired waters, or whether the discharge is temporary. Low Risk and Moderate Risk projects are eligible for Construction General Permit (CGP).

6-VT-b.2 to 6-VT-b.3 — Does the Project Qualify for a Construction General Permit (CGP) (3-9020)?; Individual Discharge Permit?

If the project is either a Low Risk or Moderate Risk construction activity pursuant to the Project Risk Evaluation, the proposed project is eligible for a CGP. If the proposed project is not eligible for coverage under the CGP, the project requires coverage under an Individual Stormwater Construction Permit Application.

Construction activity may not commence until an authorization to discharge is issued pursuant to a CGP or Individual Permit.

6-VT-b.4 — Notice of Intent (NOI) and Fee

Developers must submit the applicable NOI: NOI for Low Risk Projects,NOI for Moderate Risk Projects. DEC 401 Practice; Water Pollution Control Permit Regulations, 1 Vt. Code R. 12-033-002 § 13.3(c). The developer should file a completed NOI and all necessary attachments on a CD/DVD by mail or hand deliver to the DEC, at least sixty (60) days prior to the commencement of construction activity. Application Submittal Guidance for Stormwater Permits; Vermont Water Pollution Control Permit Regulations, 1 Vt. Code R. 12-033-002 § 13.2(b); Low Risk Site Handbook for Erosion Prevention and Sediment Control; NOI for Low Risk Projects.

A NOI must contain, at minimum, the following:

  • Name of landowner(s) and principal operator(s) and contact information;
  • Project location information, description of construction project, projected date of construction commencement and final stabilization;
  • Total acreage to be disturbed;
  • A copy of a completed Project Risk Evaluation showing the risk score for the project;
  • Name(s) of receiving water(s); and
  • Certification of accuracy of information submitted.
