BACKGROUND

The assigned TP removal rates can be used with the Virginia Runoff Reduction Method (VRRM) spreadsheets to show compliance with water quality requirements.

There are 15 practices listed in subsection 9VAC25-870-65 of the VSMP regulation. Design specifications for these practices are provided as PDF documents and are listed by year of publication.

Additional practices approved by DEQ in accordance with procedures established by the department are also listed. Practice 16 includes manufactured treatment devices (MTDs) that are hydrodynamic devices, and practice 17 includes MTDs that are filtering devices.

A VSMP authority may establish limitations on the use of specific BMPs in accordance with §62.1-44.15:33 of the Code of Virginia.
