The Department invites public comment on a final draft of the Virginia Stormwater Management Handbook (2nd Edition, 2013). This Handbook has been developed over the past few years to provide guidance pertaining to modified Virginia Stormwater Management Program (VSMP) Permit Regulations adopted in October 2011 and required to be implemented beginning on July 1, 2014. The draft Handbook is subdivided into chapters and chapter appendices, each provided as a separate PDF file on the Department's Stormwater Management Guidance webpage. The Department considers the new Handbook to be a substantial improvement in the level and quality of guidance provided, with many new topics addressed, more and better graphics, and up-to-date site design examples, among other new elements. DEQ is also asking for comments on amending the Virginia Stormwater Management Regulations to incorporate the updated Virginia Runoff Reduction Method (VRRM) Spreadsheet described in Chapter 12 of the draft Handbook. The Virginia Stormwater Management Regulations require using the Virginia Runoff Reduction Method Spreadsheet or other equivalent methodology to determine compliance with water quality design criteria for regulated land-disturbing activities. The current method required by the regulation is dated March 2011. An improved version was completed in spring of 2013, correcting some calculation formula errors and providing a Summary Tab, simplifying access to the calculated results.
The Department will receive comments regarding the draft Handbook and the updated VRRM Spreadsheet for 30 days. Comments must be received by 11:59 p.m. on October 23, 2013. All comments should be sent to the contact listed below.
