Stormwater Regulation

Stormwater Regulation (NPDES Program)
The City of Springfield is an EPA Phase 2 Small MS4 (Municipal Separate Storm Sewer Systems) Stormwater Program Participant city. The requirements of the National Pollutant Discharge Elimination System (NPDES) program are as follows:
  • Protect water quality
  • Reduce the discharge of pollutants to the maximum extent practicable
  • Satisfy the appropriate water quality requirements of the Clean Water Act
The Engineering Department helps meet these requirements in a few different ways such as public education outreach, construction site runoff control and more.

Public Education Outreach
The Public Education Outreach Program is in charge of distributing educational materials and performing outreach to inform citizens about the impacts polluted stormwater runoff discharges can have on water quality.

Public Participation & Involvement
NPDES provided opportunities for citizens to participate in program development and implementation, including effectively publicizing public hearings and / or encouraging citizen representatives on a stormwater management panel.

Illicit Discharge Detection and Elimination

NPDES is responsible for developing and implementing a plan to detect and eliminate illicit discharges to the storm sewer system (including developing a system map and informing the community about hazards associated with illegal discharges and improper disposal of waste).

Construction Site Runoff Control
It is important for NPDES to develop, implement, and enforce an erosion and sediment control program for construction activities that disturb 10,000 or more square feet of land. Controls can include silt fences and temporary stormwater detention ponds.

Post-Construction Runoff Control
Developing, implementing, and enforcing a program to address discharges of post-construction stormwater runoff from new development and redevelopment areas is important to the NPDES program. Applicable controls could include preventative actions such as protecting sensitive areas such as wetlands or the use of structural BMP's (Best Management Practices) such as grassed swales or porous pavement.
