Background


2017 VSMM is now in effect!

The 2017 Vermont Stormwater Management Manual  was adopted by rule and became effective on July 1, 2017. The  Manual and application materials are now available on the Operational Permit Application Materials page. This page contains historical documents related to the development of the 2017 VSMM.


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. 

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. The proposed rule filed with LCAR includes changes made in response to  written public comment as well as comments submitted verbally  during a public hearing held October 25th, 2016 at the Pavillion Auditorium in Montpelier.  The rule and full filing package are available below. The proposed rule as filed for Rulemaking is reflective of proposed requirements, and is not reflective of guidance, schematics, photos, or other depictions that would serve as guidance, as previously had been included in the pre-rulemaking March 1, 2016 draft The Department expects to package the content of the adopted final rule in a manual format, with applicable guidance, including design schematics and photos, subsequent to the rulemaking process.  Guidance content may be revised by the Department outside of the rulemaking process. The Department will also develop application materials and outreach in support of  the new manual in the coming months.

Background Documents

Background and Goals

The Stormwater Program began a process to update the Manual in 2009, but suspended the effort due to resource constraints. The stakeholder comments that we received during the 2009 process were carefully considered when we contracted with Stone Environmental in 2012 to evaluate the current state of stormwater management practice in four main areas of practice:

  • Site characterization standards and guidelines for infiltration-based practices;
  • Alternatives to the Channel Protection Volume (CPv) standard;
  • Integrating Low-Impact Development (LID) concepts into the Manual;
  • Maintenance plans (requirements for, and implementation of, in other jurisdictions)

The final report, Advanced Stormwater Standards Compilation, served as an important resource in this effort. Our goal for the manual revision process is to incorporate important advances in the field of stormwater management into the VSMM.

The Process

DEC convened a series of workshops focused on the specific topic areas outlined above from September 2013 to June 2014.  Meeting records, presentations, and handouts are all available below.

At the conclusion of the stakeholder process, the Stone team will prepare a draft revised VSMM. This draft will be circulated for review by the stakeholder group in early 2016 before being advanced to rulemaking by DEC. The process we have planned will offer numerous opportunities for input. The Stormwater Program staff will balance potential changes to the VSMM against the resources available within the Program to support their implementation.

Adopting Changes to the VSMM

The Vermont Stormwater Management Manual was adopted by the Vermont State Legislature in 2002 as part of the Department’s legislatively-directed process to prepare an enhanced stormwater management program. At that time, the legislature established that future changes to the VSMM must be made via rulemaking. Following this stakeholder process, DEC will proceed to adopt changes to the VSMM via rulemaking, with the goal of commencing the process in the spring of 2014. Rulemaking includes inter-agency coordination, a public hearing and comment period, and review by the legislature. Information on the rulemaking process is available from the Vermont Secretary of State’s Office.
