| 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

- 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) |
Varies but includes:
- Discharge of chlorinated water from pools
- Improper disposal of sewage and grease
- Wash off of livestock manure
- Soil erosion
- Runooff of pesticides
- Salt storage
