The following application materials have been prepared in conjunction with the 2017 VSMM.  Applications using the new manual and materials will not be processed until after July 1, 2017.  Permit applications received before July 1st should use the current application materials. All materials presented below are draft and subject to change.

Designer Training

The  Stormwater Program offered several training events on the new Manual in May to support designers in their understanding of the new requirements and preparation of stormwater permit applications under the 2017 VSMM.  The Stormwater Program expects to schedule additional opportunities for training and outreach as needed, beyond this first initial offering which focuses on permit application design and preparation. Additionally, materials from the trainings will be posted here as they become available.

VTrans Training on Subchapter 6.0 for Public Transportation Projects

VTrans is offering a training session for stormwater designers and practitioners interested in learning how to apply the new 2017 VSMM Subchapter 6.0 for Public Transportation Projects. These types of projects often present a unique set of physical constraints, with limited options for stormwater management. The goal of this training by VTrans is to provide a better understanding of how to effectively prepare permit application materials for public transportation projects in order to meet the requirements of the 2017 VSMM. If the following applies to your jurisdictional project or your client’s project subject to a Vermont Operational Stormwater Discharge Permit, this training by VTrans is for you:

  • Is your project located within the existing right-of-way of a state highway, town highway, or other public roadway? Is it associated with a trail, bicycle path, or sidewalk?
  • Will your project involve redevelopment of or improvements to an existing impervious roadway surface? Or, will it involve expansion of an existing road?

This training is FREE and is scheduled for: Monday, June 19, 2017 from 9am to noon at the Dill Building in Berlin, VT. Sign-in will be from 8:30 – 9am. Space is limited and an RSVP is required. if you would like to attend, please contact Lance Duquette of the VTrans Training Center at or 802-745-8867 or for questions related to the training contact Jon Armstrong, VTrans Stormwater Engineer at or 802 828-1332

The training will also be presented on-line live via WebEx and recorded for later viewing.  You can sign up for the WebEx at:

Rulemaking Process Has Been Completed

The Department is pleased to announce that the proposed 2017 Vermont Stormwater Management Manual Rule has completed the rulemaking process. The 2017 VSMM becomes effective on July 1, 2017.
