Stormwater Best Management Practices (BMPs)

• Waste Management of Colorado, Inc.

2
Introduction

• Stormwater permit required for
• Maintenance facilities (collection companies)
• Transfer Stations
• Material Recovery Facilities
• Landfills
• Review of BMPs for collection and transfer
  facilities.

3
Stormwater Management Plan Goals

• Identify potential sources of pollution
• Reduce or eliminate the pollutants in stormwater
  discharges

4
Identification of Potential Pollutant Sources

• Loading and unloading operations
• Outdoor storage activities
• Outdoor processing activities
• Significant sources of dust generating processes
• Areas for spills or releases

5
BMPs

• Stormwater diversion
• Detention or Retention ponds
• Oil Water Separators
• Divert flows away from sources of pollutants
• Materials handling and spill prevention
• Store vehicle fluids under cover or inside
  facility e.g. oil, antifreeze, de-icing products
• Secondary containment
• Daily removal of all MSW from Transfer Facilities

6
BMPs

• Sediment and erosion controls
• Hard surface parking lots
• Divert flows through detention or retention ponds
• Divert flows through oil water separators
• Other measures
• Housekeeping
• Lot sweeping
• Daily removal of MSW from Transfer Stations

Other Measures

• Housekeeping
