Stormwater 

Work With Us
Stormwater runoff occurs when precipitation from rain or snowmelt flows over the land surface. The addition of roads, driveways, parking lots, rooftops and other surfaces that prevent water from soaking into the ground greatly increases the runoff volume created during storms. This runoff is swiftly carried to local streams, lakes, wetlands and rivers and can cause flooding and erosion, and wash away important habitat for indigenous animals. Stormwater runoff also picks up and carries with it many different pollutants that are found on paved surfaces such as sediment, nitrogen, phosphorus, bacteria, oil and grease, trash, pesticides and metals.

​The National Pollutant Discharge Elimination System (NPDES) stormwater program regulates some stormwater discharges from three potential sources: municipal separate storm sewer systems (MS4s), construction activities, and industrial activities. Operators of these sources might be required to obtain an NPDES permit before they can discharge stormwater. This permitting mechanism is designed to prevent stormwater runoff from washing harmful pollutants into local surface waters.
CPS has years of experience and has helped numerous clients:

  • Submit Notice of Intent (NOI) applications for coverage under general permits
  • Apply for Individual NPDES Stormwater Permits.
  • Select and design Best Management Practices (BMPs)
  • Determine eligiblilty for a “No Exposure” permit
  • Perform run-off and infiltration calculation

CPS also provides a variety of field services inlcuding:

  • Stormwater compliance inspections
  • Collection and reporting of stormwater and effluent discharge samples
  • Collection and evaluation of samples for Whole Effluent Toxicity (WET) testing in support of biological/ecological evaluations or certifications
  • Non-stormwater discharge evaluations and certifications
