text: According to the United States Environmental Protection Agency, mixed waste (MW) is a waste type defined as follows; "MW contains both hazardous waste (as defined by RCRA and its amendments) and radioactive waste (as defined by AEA and its amendments). It is jointly regulated by NRC or NRCs Agreement States and EPA or EPAs RCRA Authorized States. The fundamental and most comprehensive statutory definition is found in the Federal Facilities Compliance Act (FFCA) where Section 1004(41) was added to RCRA: "The term mixed waste means waste that contains both hazardous waste and source, special nuclear, or byproduct material subject to the Atomic Energy Act of 1954."
  Mixed waste is much more expensive to manage and dispose of than waste that is solely radioactive.  Waste generators can avoid higher charge back costs by eliminating or minimizing the volume of mixed waste generated.
