Stormwater Compliance

Stormwater runoff is generated from rain and snowmelt events that flow over land or impervious surfaces, such as paved streets, parking lots, and building rooftops, and does not soak into the ground. The runoff picks up pollutants like trash, chemicals, oils, and dirt/sediment that can harm rivers, streams, lakes, and coastal waters. To protect these resources, communities, construction companies, industries, and others, use stormwater controls, known as best management practices (BMP’s). These BMP’s filter out pollutants and/or prevent pollution by controlling it at its source.



The NPDES stormwater program regulates some stormwater discharges from three potential sources: municipal separate storm sewer systems (MS4’s), 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.

  • protection of wetlands and aquatic ecosystems,
  • improved quality of receiving waterbodies,
  • conservation of water resources,
  • protection of public health, and
  • flood control.

Stormwater Pollution Prevention Plan (SWPPP)

A SWPPP is required for compliance with the National Pollution Discharge Elimination System (NPDES) General Permit and by State/Federal Regulations. The Multi Sector Permit covers the industrial activities exposed to rain water and runoff.

A SWPPP plan contains;

  • Annual comprehensive site compliance evaluations
  • Signatures on designated worksheets in accordance with the attached signatory requirements
  • Quarterly site inspections of the facility
  • Quarterly visual monitoring of stormwater discharges
  • Analytical monitoring of stormwater discharges
  • Maintenance of a rain gauge with corresponding event log on site
  • Remedy by SWPPP team of all benchmark exceedances within 90 days of notification

An example site plan (Figure1) shows potential pollutants, drainage direction and proposed outfalls.
