Six Minimum Control Measures

Under the National Pollutant Discharge Elimination System (NPDES) Phase II regulations, Loudoun County must prepare a stormwater management program containing elements that address the following six technical areas:

  1. Construction site runoff control
  2. Illicit discharge detection and elimination
  3. Pollution prevention / good housekeeping
  4. Post-construction runoff control
  5. Public education and outreach
  6. Public participation / involvement

Stormwater Management Plan

Each of these areas, identified as minimum control measures in the NPDES Phase II regulations, is discussed in the Loudoun County Stormwater Management Plan (PDF). For each of the minimum control measures, communities must identify best management practices (BMPs) and measurable goals that reflect the communities’ choices about how to satisfy the regulatory requirements. These BMPs and goals form the basis on which the success of the Phase II program can be evaluated in each community, which is ultimately the degree to which the community is satisfying the water quality requirements of the Clean Water Act.

Environmental Agencies

To assist communities, the Virginia Department of Environmental Quality (DEQ), along with the Environmental Protection Agency (EPA), has specified the minimum requirements for each of the six control measures along with recommended program elements. While Virginia’s two environmental agencies, VDEQ, and the Virginia Department of Conservation and Recreation (VDCR) continue the process of developing a unified Virginia BMP manual, the EPA has developed and is continuing to revise a list of potential BMPs that communities might use to satisfy the Phase II program requirements.
