BEST PRACTICES

Even when not required by environmental regulations, the following best practices are recommended. In some instances, best practices presented here are required by regulations.

Your facility may have a fueling system (diesel, gasoline, etc.) for vehicles or equipment that involves aboveground storage tanks. To minimize the potential for fuel spills and leaks and reduce their potential to enter the storm sewer system, implement the following best practices:

1. Cover catch basins with storm drain covers while fueling.
2. Make certain that spill kits containing dry, absorbent materials for spill response are located near the area of fueling and that staff are trained in their use.
3. Ensure that the transfer of fuel from/to fuel tanks and/or aboveground storage tanks is monitored by an attendant.
4. Provide spill response training for personnel (in most states this is required by law).
5. Post signs that give fueling instructions, spill response procedures, emergency contact information and best practices.
6. Check loading/unloading equipment (valves, pumps, flanges, and connections) regularly for leaks. Replace worn or broken equipment.

To minimize the likelihood of discharge of pollutants to storm drains from outdoor loading and unloading of material involving aboveground storage tanks, adhere to the following best practices:

1. Avoid transferring materials close to storm drain inlets.
2. Transfer liquids only in paved areas. Portland cement paving should be used if the liquid is asphalt reactive.
3. Provide contractors and haulers with copies of pertinent best management practices (BMPs). Require contractor/hauler adherence to BMP specifications. Verify proper waste disposal practices of contractors.
4. Protect all loading/unloading activities from rainfall, run-on and wind dispersal to the maximum extent practicable. Viable options include conducting loading/unloading under existing cover, or moving indoors.
5. Maintain adequate supplies of spill response equipment and materials in accessible locations near areas where spills may be likely to occur.
6. Clean up minor spills immediately.
7. Conduct regular inspections of storage and containment equipment and promptly correct deficiencies to this equipment as necessary.

Storing material outdoors, whether it is equipment, chemicals or containers, can result in potential storm water contamination. Follow these best practices to minimize potential impacts to storm water runoff:

1. Avoid dispensing from drums positioned horizontally in cradles. Dispensing materials from upright drums equipped with hand pumps is preferred. Always use drip pans and self-closing spigots if dispensing from horizontally positioned drums.
2. Store drums and containers on pallets or other structures to keep the container out of contact with storm water.
3. Store all materials in their original containers or containers approved for that use. Ensure that all containers are appropriately sealed. Store empty containers indoors or under cover before moving them off-site.
4. Properly label all chemical containers with information, including their contents, hazards, spill response and first aid procedures, manufacturer's name and address, and storage requirements. Maintain copies of MSDS on file for any materials stored and/or handled.
5. Reduce the quantities of chemicals stored outside to the minimum volume required based on variables such as release potential, usage, storage capacity, and chemical shelf life.
6. Maintain adequate supplies of spill response equipment and materials in accessible locations near areas where spills may be likely to occur.
7. Post signs at all chemical storage locations in clearly visible locations noting the materials stored, emergency contacts, and spill cleanup procedures.
8. Perform and document periodic inspections in a logbook. Inspection items should include the following: external corrosion, structural failure, spills and overfills due to operator failure, failure of piping system (pipes, pumps, flanges, couplings, hoses, and valves), visually inspect new tanks or containers for loose fittings, poor welds, and improper or poorly fitted gaskets, and Inspect tank foundations and storage area coatings.
9. Whenever possible store materials under a roof or otherwise cover stored materials to minimize storm water impacts.
10. Make sure dumpster covers are closed except when adding trash to prevent infiltration and subsequent release of oils to receiving waters.

Best practices related to waste handling and disposal include the following suggested activities:

1. Perform regular housekeeping activities in waste storage areas.
2. Reuse or recycle materials whenever possible.
3. Inspect waste management areas for spills and waste management containers for leaks.
4. Track waste generated, evaluate the process generating the waste and look for ways to reduce waste generation.
5. Characterize waste streams.
6. Find substitutes for harmful chemicals; properly dispose of unusable chemical inventory.
7. Segregate and separate wastes.
8. Do not dispose of liquid wastes such as oils or hazardous materials into dumpsters.
9. Maintain adequate supplies of spill response equipment and materials in accessible locations near areas where spills may be likely to occur.
10. Equip waste transport vehicles with spill containment equipment.
11. Perform and document in a logbook periodic inspections of hazardous and non-hazardous waste storage areas. Inspection items should include the following: external corrosion, structural failure, spills and overfills due to operator error, failure of piping system (pipes, pumps, flanges, couplings, hoses, and valves), visually inspect new tanks or containers for loose fittings, poor welds, and improper or poorly fitted gaskets, and inspect tank foundations and storage area coatings.

Training employees in proper procedures to reduce your facility's impact on the environment is a best practice. More detailed training information is provided in the regulatory requirements sections of the EVC. Employee training may include the following:

1. Spill response training for personnel who handle hazardous material,
2. Fork lift training,
3. Storm water pollution prevention education,
4. Right-to-know awareness training,
5. Hazardous materials management,
6. Emergency preparedness, and
7. Awareness-level training, for example, a general overview of the school's environmental management system.
