5.2.2 Transportation and Storage
This stage includes initial transport from curbside collection, as well as transfers from the initial collection vehicle to other vehicles or sites, or both.
Materials can be released from their containers during transportation and compacting. The public and collection workers can be exposed to hazards if materials are released from the vehicle during transport.
These released materials can also enter the environment through air, soil, or water.
Materials that promote spontaneous combustion can create a fire hazard or expose the environment to consequent emissions of a fire.
5.2.4.1 Composting
Municipal composting processes involve the handling and processing of predominantly organic waste.
Materials inadvertently added to the compost stream can be spilled as a result of these operations, and will either be absorbed by adjacent waste or commingle with leachate from the composting system.
These materials will be subject to chemical and biological degradation.
Materials incorporated into the compost leachate can enter the environment through air, soil (groundwater), or sewers used to manage leachate. Materials disposed of through composting systems can enter the environment via end use一spreading on land. People or animals can be exposed, via food or groundwater, to listed hazards.
5.2.4.2 Septic Systems and Municipal Sanitary Sewer Systems
Materials that are disposed of in drains will enter septic or municipal sanitary sewer systems. Surface water or groundwater can be contaminated by wastes escaping through leaks in these systems or by the discharge from the treatment process. During normal maintenance, workers in the sewer systems can be exposed to hazardous materials (e.g. flammables).
Some HHW materials can contain compounds (e.g., toxic metals) that can accumulate in the sludge produced during the waste water treatment process. These compounds can enter the environment if the sludge is applied on land or the by-product of its incineration (fly ash) is disposed of in lanfills.
5.2.4.3 I andfill
Landfill processes involve the depositing, moving (by scraping), further compacting, and covering of waste. Materials can be spilled as a result of these operations and will either be absorbed by adjacent waste or commingle with the landfill leachate.
Leachate can cross landfill boundaries, and it can enter the environment through air, soil (groundwater),
leachate collection systems, or sewers.
Landfill workers can be exposed to hazards during the handling and inspection of waste.CSA Z752-03 pdf download.
