What is the nature of "Subtitle D" landfills?

"Subtitle D" landfills refer specifically to the regulatory framework established under the Resource Conservation and Recovery Act (RCRA) for the disposal of municipal solid waste (MSW). This designation provides guidelines for the design, operation, and closure of landfills that accept non-hazardous waste commonly produced by households and businesses. Subtitle D landfills are designed to ensure that MSW is disposed of in a manner that is safe and minimizes risks to human health and the environment.

This is in contrast to other types of landfills that might focus on temporary waste disposal solutions, handle hazardous wastes, or serve specific waste processing functions like composting. Therefore, the characterization of Subtitle D landfills as permanent repositories for municipal solid waste is accurate, as they serve the purpose of effectively managing and containing the waste generated by communities over time, following strict regulations to protect ecological and public health.
