Even when not required by environmental regulations, the following best practices are recommended.

1. Maintain good housekeeping. Keep areas clean and free from litter. Sweep walkways and roadways.
2. Prevent and respond to spills quickly. Do not let material enter the storm water collection system. Keep adequate spill response kits and equipment available to respond to spills of oil, fuel, grease and train responders in proper response procedures.
3. Control or eliminate sources, for example:
   · Reduce the use of potential pollutants through waste minimisation techniques.
   · Minimise the use of fertilisers, pesticides, herbicides etc.
   · Don't allow run off from activities such as car or vehicle washing to enter sewers or drains.
   · Control irrigation so that paved areas such as footpaths, roadways and car parks are not wetted.
   · Clean up leaves and lawn clippings so they don't enter rain water collection systems.
   · Encourage people to not litter. Place litter bins in strategic locations and maintain them periodically.
4. Train employees and students in the importance of storm water pollution control. Some employees should be trained in spill response techniques. All should be trained to not discharge material to the storm water collection system.
5. Where appropriate or feasible, invest in treatment and storm water control infrastructure including drop inlets, channels, retention and detention basins, treatment vaults, infiltration galleries, filters, oil/water separators, etc.
6. Use riprap, vegetation, slope stabilisation to control sediment and erosion. Control run off from construction and excavation activities.
7. Perform periodic inspections to identify potential sources of storm water pollution and assess effectiveness of control measures.
