Special Requirements for Containers

(1) An empty container shall be crushed flat, shredded, or similarly reduced in volume to the maximum practical extent or filled with solids before it is buried beneath the surface of a landfill. (2) A partially empty container, before it is buried beneath the surface of a landfill, shall be: (a) Filled with solids compatible with the wastes already in the container; or (b) Crushed to the maximum practical extent to eliminate void spaces; or (c) Emptied and the empty container crushed flat, shredded, or similarly reduced in volume. (3) To be considered "filled with solids" in compliance with 310 CMR 30.630(1) or (2)(a), a container shall be filled in compliance with 310 CMR 30.630(3)(a) or (b), whichever results in less void space. (a) The container shall be filled to within 7.6 centimeters (three inches) of the top of the container, or (b) The contents of the container shall occupy 90% or more of the volume of the container. (4) For the purposes of 310 CMR 30.630, the term "partially empty container" shall mean a container that is neither an empty container (see 310 CMR 30.010) or a container that is "filled with solids" (see 310 CMR 30.630(3)). (5) Landfill disposal of small containers of hazardous waste in overpacked drums (e.g., lab packs) is prohibited.
