Storm Water Pollution Prevention Plans, Sampling & Sample CollectionStorm Water Pollution Prevention Plans, Sampling & Sample Collection

The Environmental Protection Agency (EPA) in 1990, published final regulations for the National Pollutant Discharge Elimination System (NPDES) that establish storm water permit requirements. The NPDES regulates the discharges of storm water to waters of the Unites States from construction projects that covers five or more acres of soil disturbance.

The NPDES regulations require that a Storm water Pollution Prevention Plan (SWPPP) be prepared for each site that would include the following components:

  • Site map showing outfalls, drainage areas, industrial activities, and exposed pollutant sources
  • Description of activities at the site
  • Description of exposed industrial activities and previous spills, if any
  • Identification of non-storm water discharges
  • Identification and elimination of illegal connections
  • Risk assessment and feasibility study for this specific site
  • Description of existing storm water management and water quality controls
  • Description of proposed storm water management and water quality controls
  • Monitoring procedures
  • Training guidelines
  • Inspection schedule and prevention Implementation
  • Corporate signatures

Industrial facilities with wastewater treatment systems are also require to have Spill Prevention, Control and Countermeasure Plan (SPCC) to identify and eliminate possible non-authorized discharges to the storm drain.
