Information: This is an edit page for the Stormwater Manual editors
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
  • Rinse water and wash water discharges during cleanup
  • Temporary outdoor storage
  • Runoff from degreasing and re-surfacing
Turf and Landscaping
  • Non-target irrigation
  • Runoff of nutrients and pesticides
  • Deposition and subsequent washoff of soil and organic matter on impervious surfaces
  • Improper rinsing of fertilizer/pesticide applicators
Unique PSH Operations (Pools, Golf Courses, Marinas, Construction, Restaurants, Hobby Famrs)

4. Vegitation
Construction Sequence
Complies with planting specs
Topsoil complies with specs in composition and placement
Soil properly stabilized for permanent erosion control
5. Final Inspection
Dimensions per plans
Pretreatment operational
Inlet/outlet operational
Soil/ filter bed permeability verified
