Dirt, oil, and trash that collect in parking lots and paved areas can be carried by stormwater runoff into a storm sewer and eventually reach local water bodies.
- Sweep up litter, trash, and dirt from sidewalks, driveways, and parking lots, especially from around storm drains.
- Keep lids closed on grease storage containers and trash dumpsters so stormwater will not be contaminated. Make sure the containers are not leaking.
- Businesses and local governments should provide an adequate number of appropriately sized containers.
- Owners of commercial dumpsters should be certain their containers are of adequate size to handle the waste they generate. Trash receptacles and dumpsters should be emptied on an appropriate schedule.
- Keep chemicals and other materials stored onsite under cover to prevent contaminating runoff.
- Use all chemicals responsibly and properly dispose of wastes.
- Ensure the proper disposal of all wastewater into the wastewater sewer system.
- Report any chemical or oil spill to emergency response agencies. Be prepared for spill incidents to keep spills from harming the environment.
- Minimize the amount of exposed soil and divert stormwater away from disturbed or exposed areas of the construction site.
- Install best management practices (BMPs) such as silt fences, vegetative cover and other sediment and erosion controls, and properly maintain them.
- Wash mud from vehicles in areas where the water will not enter the storm sewer or run to a nearby water body.
- Properly dispose of trash and other wastes.
- Provide cover over fueling stations and provide for spill containment.
- Wash vehicles at a commercial wash or other properly designated facility that treats its wastewater before sending it to the wastewater sewer.
- Clean animal living quarters to collect and properly dispose of waste.
- Do not wash animal waste into storm drains.
- Avoid animal waste contaminating stormwater by diverting runoff and by covering stalls
