Storm Water Pollution Prevention Plan (SWPPP)

Stratus Environmental, Inc. has successfully developed and implemented SWPPPs for construction activities at large facilities like AMTRAK junction, gasoline service stations, and vacant lots. These SWPPPs were developed in accordance with the requirements identified in the State Water Resource Control Board (SWRCB) National Pollutant Discharge Elimination System (NPDES) permits.

Our SWPPPs adopt a step-by-step evaluation of each construction task to identify potential pollutant sources that may affect quality of discharges resulting from construction activities. The potential primary pollutants that are commonly encountered during construction work are in the form of soil erosion, wind erosion, and dust nuisance. Both storm water and non-storm water sources are considered during this SWPPP development. Once a potential pollutant source is identified, strategic BMPs are developed that target not only compliance with SWRCB NPDES requirements, but also keep the SWPPP implementation costs low.

Stratus’ SWPPP emphasizes pre-construction planning that aids in eliminating/minimizing unnecessary tasks that contribute to secondary pollutant sources (For e.g., at AMTRAK Facility in Los Angeles, the requirement for tire wash (that would have resulted in wash water collection/treatment) was eliminated by the use of rumble strips and periodic sweeping). Some of the key best management practices adopted in Stratus’ SWPPP are listed below:

  • Construction Scheduling and Planning
  • Rumble Strips at Entry/Exit Locations
  • Silt and Sediment Fencing
  • Straw Wattle Barrier
  • Sand Bag Barrier
  • Street Sweeping
  • Geo-Textiles and Mats
  • Spill Prevention Containments
  • Storm-Sewer Inlet Protection Covers
  • Site Reconnaissance Prior to and After Forecasted Storm Events
