Stormwater Management & MS4

CEG’s stormwater experts develop MS4 programs that achieve regulatory compliance and create value.

The National Pollutant Discharge Elimination System (NPDES) Program regulates point source discharges to streams and rivers. At the local level, Municipal Separate Storm Sewer Systems (MS4s) that discharge to U.S. waters need to develop robust Stormwater Management Programs and Pollutant Reduction Plans (PRP) or Total Maximum Daily Load (TMDL) Plans.


  • Develop, implement, and enforce a quality and quantity-based stormwater management program (SWMP).
  • Recognize and increase awareness of stormwater as a point-source pollutant.
  • Manage stormwater as any other point-source pollutant (i.e. wastewater, industrial, etc.).
  • Generate Infrastructure Capital Improvement Plans that provide structure and fiscal clarity for permitting compliance and daily operations.

CEG’s stormwater experts develop MS4 programs that achieve regulatory compliance and create value.


CEG has successfully contributed to MS4 programs for 10 municipalities, 1 university, and 2 military bases across 4 states (GA, MD, NY & PA).


CEG’s Environmental Services Team is comprised of MS4 experts, Professional Engineers, Environmental Scientists, and support staff.
