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.
Outdoor Handling of Material
To minimise the likelihood of discharge of pollutants to storm
water from outdoor loading and unloading of material, adhere to
the following best practices:
- Avoid transferring materials close to storm drain inlets.
- Transfer liquids only in paved areas. Portland cement paving
should be used if the liquid is asphalt reactive.
- 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.
- 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.
- Maintain adequate supplies of spill response equipment and materials
in accessible locations near areas where spills may be likely
to occur.
- Clean-up minor spills immediately.
- Conduct regular inspections of storage and containment equipment
and promptly correct deficiencies to this equipment as necessary.
Outdoor Storage of Material
Storing material outdoors, whether it is equipment, chemicals
or containers, can result in potential storm water contamination.
Follow these best practices to minimise potential impacts to storm
water runoff:
- 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.
- Store drums and containers on pallets or other structures to
keep the container out of contact with storm water.
- 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.
- 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.
- 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.
- Maintain adequate supplies of spill response equipment and materials
in accessible locations near areas where spills may be likely
to occur.
- Post signs at all chemical storage locations in clearly visible
locations noting the materials stored, emergency contacts, and
spill cleanup procedures.
- Perform and document periodic inspections in a logbook. 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.
Waste Handling and Disposal
Best practices related to waste handling and disposal include the
following suggested activities:
- Perform regular housekeeping activities in waste storage areas.
- Reuse or recycle materials whenever possible.
- Inspect waste management areas for spills and waste management
containers for leaks.
- Track waste generated, evaluate the process generating the waste
and look for ways to reduce waste generation.
- Characterise waste streams.
- Find substitutes for harmful chemicals; properly dispose of
unusable chemical inventory.
- Segregate and separate wastes.
- Do not dispose of liquid wastes such as oils or hazardous materials
into dumpsters.
- Maintain adequate supplies of spill response equipment and materials
in accessible locations near areas where spills may be likely
to occur.
- Equip waste transport vehicles with spill containment equipment.
- 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.
Employee Training
Training employees on 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:
- Spill response training for personnel who handle hazardous material,
- Fork lift training,
- Storm water pollution prevention education,
- Hazardous materials management,
- Emergency preparedness, and
- Awareness-level training, for example, a general overview of
the school's environmental management system.
General Maintenance/Repair Work
When performing general vehicle repair/maintenance work, implement
the following to the maximum extent practical:
- Drain and crush oil filters (and oil containers) before recycling
or disposal. Store crushed oil filters and empty lubricant containers
in a leak-proof container - covered if outdoors.
- Drain and properly dispose of all fluids and remove batteries
from vehicles, and equipment.
- Recycle or properly dispose of the following: greases, oils,
antifreeze, brake fluid, cleaning solutions, hydraulic fluid,
batteries, transmission fluid, and filters.
- Use biodegradable products and substitute materials with less
hazardous properties where feasible.
- Maintain clean equipment by eliminating excessive amounts of
external oil and grease buildup. Use water-based cleaning agents
or non-chlorinated solvents to clean equipment.
- Store mechanical parts and equipment that may yield even small
amounts of contaminants (i.e., oil or grease) under cover and
away from drains.
- Develop regular maintenance and inspection programs for oil/water
separators (if they exist).
- Sweep or vacuum the shop floor frequently.
- Designate specific areas indoors for parts cleaning.
- Clean up any spill promptly.
- Keep rags, mops, absorbents, and other cleanup supplies readily
accessible to all work areas.
- Never sweep or flush wastes into a sanitary sewer or storm drain.
- Promptly transfer drained fluids to a designated waste storage
area.
- Place bulk fluids, waste fluids, and batteries in secondary
containment to capture accidental spills.
- Service "pits" should have concrete floors and not
earthen floors or floors with drains.
- Service bays within the facility should be segregated by operation
(brakes, radiator, oil changing, etc.) to avoid cross-contamination.
Waste Reduction and Recycling
To minimise the amount of waste generated at your facility,
consider the following:
- Recycle automotive fluids, solvents, cleaners, absorbents, and
wash waters; when the useful life is finished.
- Use self-contained sinks and tanks when cleaning with solvents.
- Automotive fluids are not acceptable for disposal to the sanitary
sewer, storm drain, or garbage.
