A Storm Water Pollution Prevention Plan (SWPPP) describes management and monitoring practices and procedures that reduce industrial pollutant discharges to storm waters. The major objectives of a SWPPP are to:

• Identify sources of pollutant discharges;
• Identify non-stormwater discharges
• Identify and implement Best Management Practices (BMPs) to reduce the pollutant discharge.

This SWPPP describes potential sources of pollution at the Corporation Yard and identifies BMPs for each potentially polluting activity. BMPs are management practices or control measures that are implemented in order to significantly reduce or eliminate the sources of pollutants. BMPs are any schedule of activities, prohibitions, good housekeeping practices, pollution prevention practices, maintenance procedures or other practices that prevent or reduce discharge of pollutants directly or indirectly to storm drain culverts, catch basins, flood control channels, roadside ditches or any other conveyance to surface waters.
