PSH Operation Polluting Activity
Vehicle Operations
  • Improper disposal of fluids down shop and storm drains
  • Spilled fuel, leaks and drips from wrecked vehicles
  • Hosing of outdoor work areas*Wash water from cleaning
  • Uncovered outdoor storage of liquids/oils/batteries spills
  • Pollutant wash-off from parking lot
Outdoor Materials
  • Spills at loading areas
  • Hosing/washing of loading areas into shop or storm drains
  • Wash-off of uncovered bulk materials and liquids stored outside, of particular concern in MN are road salt storage areas
  • Leaks and spills
Waste Management
  • Spills and leaks of liquids
  • Dumping into storm drains
  • Leaking dumpsters (Dumpster juice)
  • Wash-off of dumpster spillage
  • Accumulation of particulate deposits
Physical Plant Maintenance
  • Discharges from power washing and steam cleaning
  • Wash-off of fine particles from painting/sandblasting operations
