The ways in which P2 is achieved varies from one sector to another, but typically there are nine common opportunities:

===Dumpster management===

{| class="wikitable"

Dumpsters can be a major source of pollution that can affect [[water quality]]. When dumpster lids are left open, rainwater is able to mix with the trash, resulting in a leaking fluid, or “dumpster juice”, which can contain toxic organic and inorganic materials. If not treated, this dumpster juice can enter the storm drain system, contributing to poor water quality.

 

===Grease management===

!Dumpster management

Restaurants produce grease and other wastes as a by-product of normal food preparation. If grease is dumped or washed into sewers or storm drains, it can cause sanitary sewer overflows or stormwater runoff pollution. Restaurants can implement simple and low-cost P2 practices and train workers to properly dispose of used waste.

===Parking lot maintenance===

!Grease management

Maintenance operations have the potential to pollute stormwater runoff if sensible P2 practices are not employed. This is particularly true of power washing, which can deliver sediment, [[nutrients]], [[heavy metals]], hydrocarbons and other pollutants into the storm drain system.

===Building maintenance===

!Parking lot maintenance

Some building maintenance practices produce polluted wash-water that can directly enter the storm drain system during dry weather, whereas others deposit fine particles or liquids that can wash away into stormsewers during wet weather.

===Landscaping and grounds care===

!Building maintenance

Landscaping services are generally performed by a lawn care/ landscaping contractor or an in-house maintenance crew. Poor landscaping practices can create stormwater pollution, particularly in urban areas where soils are compacted.

===Vehicle maintenance and repair===

!Vehicle maintenance and repair

Often, vehicles that are wrecked or awaiting repair can be a concern if leaking fluids are exposed to stormwater runoff. Vehicle maintenance and repair can generate oil and grease, trace metals, hydrocarbons, and other toxic organic compounds. When vehicles are washed on impervious surfaces, dirty wash water can contaminate stormwater with sediments, phosphorus, metals, oil and grease, and other pollutants that can degrade water quality.

===Fuelling stations===

!Fuelling stations

Delivery of pollutants to the storm drain can be sharply reduced by well designed fuelling areas and improved operational procedures. The risk of spills depends on whether the fuelling area is covered and has secondary containment.

===Snow and ice management===

!Snow and ice management

Ontario experiences severe winter weather with large amounts of snowfall. Common snow removal practices include application of de-icer. De-icer is usually made from a urea compound or rock salt. Many property managers apply the products indiscriminately, assuming that more is better. However these de-icers wash into local waterways when the snow starts to melt. The key to de-icer usage is to apply it sparingly, and to remove most of the snow before application. See also [[salt management]].
