Stormwater Minimum Design Criteria

Session Law 2013-82 required the Department of Environmental Quality to convene a Minimum Design Criteria team that included industry experts, engineers, environmental consultants, university faculty and other stakeholders. The law tasked the team with the following:
  • To consult with the department in developing minimum design criteria that encompass all requirements for siting, design, construction and maintenance of stormwater BMPs. The minimum design criteria shall be developed with the goal of generating state stormwater permits that comply with water quality standards. DEQ shall submit its recommendations to the N.C. Environmental Review Commission by Feb. 1, 2015.
  • To consult with the N.C. Environmental Management Commission in developing a fast-track permitting process for issuing state stormwater permits without a technical review when all BMPs comply with all MDCs and the permit application is prepared by a qualified individual. The commission shall adopt a fast-track permitting rule by July 1, 2016.

The Minimum Design Criteria Team met monthly from March 2014 until August 2015. Below are materials team members used to prepare for meetings, as well as meeting minutes, work products and other related documents.
