An example of a narrow street from Woodbury, Minnesota. Reducing street width reduces the amount of pollution on impermeable surfaces and is therefore an effective pollution prevention practice.

The 2008 version of the Stormwater Manual (Version 2) contains pollution prevention (P2) fact sheets for residential, municipal and commercial/industrial land uses. Material from those fact sheets comprises the information contained on this page. To link to the original document in Microsoft Word format, click File:Pollution Prevention.docx. In addition, there is a fact sheet for businesses. We anticipate eventually including information for specific pollution prevention practices.

For more information on pollution prevention in general, see MPCA's page on pollution prevention. The MPCA has also produced a document titled Pollution Prevention and the MS4 Program: A Guide on Utilizing Pollution Prevention Activities to Meet MS4 General Permit Requirements. This document provides communities regulated under the Minnesota Municipal Separate Storm Sewer Systems (MS4) General Permit with basic tools and information that will lead to increased use of pollution prevention (P2) activities within stormwater pollution prevention programs (SWPPPs) and local stormwater programs.

Residential Practices

Residential pollution prevention practices are household and neighborhood activities that prevent or reduce the contamination of stormwater. Residential pollution prevention practices prevent or reduce stormwater contamination from sources such as yards, driveways, sidewalks, and household products.

These practices are often simple, low cost behavioral changes that improve subwatershed water quality by minimizing the introduction of pollutants including sediment, nutrients, metals, bacteria, trash, oil, and toxins.

Each of these practices are highly suitable and effective in cold climates. Each practice varies in its ability to control pollutants generated from residential land uses. A variety of methods may be used for each of these practices. See Photo Credits and References for further information

Practice Method Image
Fertilizer and pesticide management 1 Reduce or eliminate the need for fertilizer and pesticides by practicing natural lawn care, planting native vegetation, and limiting chemical use; follow Minnesota Statutes Chapter 18C and federal regulatory requirements on fertilizer and pesticide storage and application if used.
Fertilizer pesticide management.jpg
Litter and Animal Waste Control 1 Properly dispose of pet waste and litter in a timely manner and according to local ordinance requirements.
Litter animal waste control.jpg
Yard Waste Management 1 Prevent yard waste from entering storm sewer systems and water bodies by either composting or using curbside pickup services and avoiding accumulation of yard waste on impervious surfaces; keep grass clippings and leaves out of the street.
Yard waste management.jpg
Household Hazardous Waste (HHW) Control 1 Ensure that hazardous waste, including paints, stains, solvents, cleaning products, used motor oil, antifreeze, and pesticides, are disposed of properly by participating in a County household hazardous waste collection program; properly store hazardous waste items.
Household hazardous waste.jpg
Alternative Product Use Use less harmful products including alternative cleaning solutions, pesticides, fertilizers, automotive and paint products to reduce the amount of toxic substances released into sewer systems.
Alternative product use.jpg
Better Car and Equipment Washing 1 Wash cars less often and on grassy areas using phosphorus free detergents and non-toxic cleaning products or use commercial car washes to prevent dirty wash water from flowing to storm sewer systems and water bodies.
Better car washing.jpg
Better Sidewalk and Driveway Cleaning 1 Sweep sidewalks and driveways and dispose of sweepings in the trash instead of using hoses or leaf blowers to clean surfaces.
Better sidewalk driveway cleaning.jpg
Better Sidewalk and Driveway Deicing 1 Reduce or eliminate the need for deicing products by manually clearing sidewalks and driveways prior to deicer use; use environmentally-friendly deicing products when possible, apply sparingly and store properly if used.
Better sidewalk driveway deicing.jpg
Proper Pool Discharge 1 Check local ordinances for pool water discharge requirements; pool water should be discharged to sanitary sewer systems or held for a week or more without addition of chlorine prior to spreading over pervious areas to prevent stormwater contamination.
Proper pool discharge household.jpg
Exposed Soil Repair 1 Use native vegetation or grass to cover and stabilize exposed soil on lawns to prevent sediment wash off.
Exposed soil repair.jpg
Native Landscaping Reduce turf areas by planting native species to reduce and filter pollutant-laden runoff and prevent the spread of invasive, non-native plant species into the storm sewer system.
Native landscaping.jpg
Healthy Lawns Maintain thick grass planted in organic-rich soil to a height of at least 3 inches to prevent soil erosion, filter stormwater contaminants, and absorb airborne pollutants; limit or eliminate chemical use and water and repair lawn as needed

Municipal practices

Municipal pollution prevention practices are public operation and maintenance activities and educational efforts implemented by municipal staff that prevent or reduce the contamination of stormwater.

Municipal pollution prevention practices prevent or reduce stormwater contamination from public sources such as streets, parking areas, maintenance vehicles, storm and sanitary sewers, dumpsters, swimming pools and other potential stormwater hotspots. These practices improve subwatershed water quality by minimizing the introduction of pollutants including sediment, nutrients, metals, bacteria, trash, oil, and toxins. Each of these practices is highly suitable and effective in cold climates. The following tables indicate there is wide variability in the pollutants controlled by various municipal pollution prevention practices and in the methods used for each of these practices. Some of these practices are effective in controlling pollutants from potential stormwater hotspots.

Industrial and commercial practices

Industrial and commercial pollution prevention practices are private operation and maintenance activities implemented by owners or individuals responsible for industrial and commercial sites that prevent or reduce the contamination of stormwater. Note that certain industrial activities and sites could be covered under the NPDES Industrial Permit.

Industrial and commercial pollution prevention practices prevent or reduce stormwater contamination from concentrated impervious surfaces and potential stormwater hotspots such as streets, parking areas, vehicles, smokestacks, and dumpsters. These practices improve subwatershed water quality by minimizing the introduction of pollutants including sediment, nutrients, metals, bacteria, trash, oil, and toxins. The tables below indicate there is a wide variation in the pollutants controlled by various industrial and commercial pollution prevention practices and wide variation in some of the methods used for each of these practices. Some of these BMPs may be effective for controlling pollutant loading from [[Potential stormwater hotspots|potential stormwater hotspots.
