  "field": "Environment",
  "definition": "1. The procedure an operator must go through when a landfill reaches the legal capacity for solid waste. No more waste can be accepted and a cap usually is placed over the site. The cap is then planted with grasses and other ground covers.\n\n2. The point at which a company permanently stops activity (although it may still retain liabilities for unforeseen environmental or safety concerns).\n\n3. The procedure a landfill operator must follow when a landfill reaches its legal capacity for solid ceasing acceptance of solid waste and placing a cap on the landfill site.\n\n4. Closure refers to the elimination of an underground discharge into the ground. This can be the physical closure of an injection well (for example, by removing the well or plugging the well with cement or by re-routing the fluid into a holding tank or into a sewer) or the re-configuration of an injection well in such a way that certain fluids can no longer enter the well. An example would be filling the floor drains in the service area with cement so that motor vehicle service fluids can no longer enter the shallow disposal system but still allowing sanitary waste from bathrooms and sinks to enter the system.\n\n5. The procedure that a solid or hazardous waste management facility undergoes to cease operations and ensure protection of human health and the environment in the future.\n\n6. Steel or aluminum coverings such as bottle caps and jar lids for containers other than can ends.",
