The new post-construction water quality requirements (Part IIB of the Virginia Stormwater Management Program Regulation - 9VAC25-870) require approval from the Department of Environmental Quality (DEQ) for use of proprietary BMPs in Virginia.

DEQ has issued guidance that describes a process for approving these proprietary BMPs and assigning pollutant removal credits: “Interim Use of Stormwater Manufactured Treatment Devices (MTDs) To Meet The New Virginia Stormwater Management Program (VSMP) Technical Criteria, Part IIB Water Quality Design Requirements” (Guidance Memo No. 14-2009). The MTD Registration Form (Attachment 1 of Guidance Memo No. 14-2009) is provided here as a MSWord document. If you have questions regarding a MTD evaluation, please contact Robert E. Cooper, P.E., at Robert.Cooper@deq.virginia.gov or 804-698-4033.

MTDs meeting the criteria of the guidance are listed on this page. They are separated into Hydrodynamic Manufactured Devices and Filtering Manufactured Devices. Information received and considered by DEQ for determining phosphorus removal efficiency for the MTDs listed here are provided on the MTD Applications & Additional Information webpage.
