Answer: (D)

Land disposal restrictions require hazardous waste to be treated to reduce its hazardous constituents before it can be disposed of on land. The treatment standards specify how much or what type of treatment must be applied so the waste is less toxic or less able to move through the environment once land disposed. These rules apply to wastes that are listed as hazardous or that exhibit hazardous characteristics, and they are designed to prevent harmful constituents from leaching into soil and groundwater. Compliance involves treating the waste at a permitted facility to meet the standard, maintaining proper documentation, and using the waste manifest to verify treatment. Treatments can include physical, chemical, or biological processes, stabilization, or destruction, depending on the waste and the specific standard. The goal is to minimize environmental risk throughout the disposal process. These restrictions focus on how waste is treated and disposed, not on unrelated topics like parking lots, employee breaks, or corporate governance.
