Stormwater Pollution Prevention Program (SWPPP)

The City of Brooklyn Center is included in a group of communities with populations greater than 10,000 that are federally required to obtain a Municipal Separate Storm Sewer System (MS4) permit for managing non-point source storm water. Non-point source storm water is generally the overland flow of storm water that does not originate from a single pipe, otherwise known as point-source storm water.

The Phase II National Pollution and Discharge and Elimination System (NPDES) permitting process requires cities such as Brooklyn Center to file a Phase II NPDES permit with the Minnesota Pollution Control Agency (MPCA) which addresses how the City will regulate and improve storm water discharges. The permit must include a Storm Water Pollution Prevention Program (SWPPP) addressing all the requirements of the permit.  The City is also responsible to put in place Best Management Practices (BMP's) to control pollution and provide clean storm water discharge to the Maximum Extent Practicable (MEP).

BMPs are programs and policies used to to reduce or prevent pollution of surface and groundwater. 

Rain Barrels
A rain barrel is a container used to catch water from a downspout. Rain barrels reduce the amount of storm water runoff by collecting roof runoff and storing the rainwater for future use.  

Rain Barrel Benefits:
  1. Rain barrels conserve water and help lower utility costs.
  2. Rain barrels reduce water pollution by reducing stormwater runoff, which can contain pollutants such as sediment, oil, grease, bacteria and chemicals.
  3. Rain barrels reduce stormwater runoff to the local storm drain system and reduces the velocity of water entering local water bodies. 
  4. Rain barrels can be arraigned to slowly release the collected rainfall to areas that can soak up water to increases groundwater recharge. 
  5. Rain water is naturally soft and does not contain chemicals such as chlorine and fluoride which is ideal for exotic indoor plants. 

Rain barrels are available to purchase online and at most hardware stores, or you can make your own. For instructions on how to assemble a rain barrel, see the Ramsey-Washington Metro District Rain Barrel guide below. Visit the Recycling Association of MN website for rain barrel distribution events.
