		Radioactive waste is waste material containing radioactive chemical elements that does not have a practical purpose.
		Waste can also be generated from the processing of fuel for nuclear reactors or nuclear weapons.
		While radioactive waste is not as sensitive to disruption as an active nuclear reactor, it is often treated as regular waste and forgotten.

	Mixed Waste Processing
		When garbage is mixed, the value and recyclability of some materials may be reduced by contamination (such as newspaper) or breakage (such as glass).
		The solid waste management field is changing rapidly; it is impossible to predict the types of superior technologies that may emerge in the next five to ten years.
		For example, a waste flow clause may undermine the community's or waste generator's right to recycle and sell aluminum cans or collect materials that are not recycled at the MWP facilities such as newspaper, yard waste, or office paper.

	The Mixed Waste Website - Perma-Fix Environmental Services - Introduction
		In the waste disposal industry and in regulatory parlance, the term "mixed waste" refers specifically to waste which is regulated as both radioactive and hazardous waste.
		The radioactive component of mixed waste, while posing a challenge from a health, safety, and environmental protection standpoint, is usually not the controlling factor for treatment.
		Because these tend to be difficult waste streams to manage and facilities with the proper technology and permits are not ubiquitous, the technology required to process the waste is the most influential factor in deciding where the waste will be sent for treatment, storage and disposal.

	IEER: Comments on DOE Advanced Mixed Waste Treatment Project Draft EIS
		The waste under consideration is classified as "retrievably-stored transuranic waste" since it is located at an above-ground storage area (as opposed to transuranic waste that has been buried or transuranic contaminated soils).
		Approximately 25,000 cubic meters of the waste to be treated does not meet the minimum radioactivity threshold of TRU waste and thus could not ordinarily be disposed of in WIPP.
		However, according to Table F-1-6 if all the waste suspected of containing PCBs over the limit, all ignitable waste, and all waste with excess liquids were incinerated, then the total volume of waste incinerated would be 26, 572 cubic meters or 41% of the waste.

	The Hazardous Wastes Website - Perma-Fix Environmental Services - Introduction
		Hazardous waste is waste that has been classified as hazardous under the Resource Conservation and Recovery Act (RCRA) of 1976, as amended, or the Toxic Substances Control Act (TSCA).
		Waste is considered hazardous if it appears on one of four lists published in the Code of Federal Regulations (40 CFR Part 261).
		If the waste does not appear on one of the hazardous waste lists, it still might be considered hazardous if it demonstrates one or more of the four characteristics of being ignitable, corrosive, reactive, or toxic.

		One challenging aspect of mixed waste is that radioactive waste is regulated by the Atomic Energy Act (AEA) and hazardous materials are regulated under the Resource Conservation and Recovery Act (RCRA).
		This type of waste is either listed as a hazardous waste in Subpart D of 40 CFR Part 261.31-33 or which exhibits any of the hazardous waste characteristics identified in Subpart C of 40 CFR Part 261.20-24 (ignitability, corrosivity, reactivity, toxicity).
		Exceptions to the production of mixed waste includes Liquid Scintillation Fluids which can be legally shipped to a contract waste disposal vendor to be burned, and radioactive materials mixed with a hazardous component that can be neutralized or deactivated in the laboratory.

	Mixed Waste Segregation
		Volume reduction of mixed waste (RCRA regulated waste combined with radioactive waste) is achievable by segregating the TCA mixed waste from the other radioactive liquid wastes generated in the laboratory.
		A separate liquid radioactive waste container was obtained to hold only the TCA rinses instead of combining the rinses with all the other liquid radioactive waste.
		The low-level aqueous radioactive waste is held for decay-in-storage and subsequently drained to the publicly owned treatment works in accordance with 10 CFR 20 Subpart K. The disposal costs for one gallon of mixed waste are approximately $158, including the actual disposal cost, analysis, and all personnel time including pickup and paperwork review.

	Mixed waste
		Waste handlers and generators who meet certain conditions specified in 40 CFR 266.230 or 266.315 may have their LLMW exempted from most Resource Conservation and Recovery Act (RCRA) Subtitle C storage and treatment and manifesting regulations.
		At that time, the waste is once again subject to hazardous waste regulation under 40 CFR 260-271 and the time period for accumulation of a hazardous waste as specified in 40 CFR 262.34 begins.
		Once removed from storage, your waste may be eligible for the transportation and disposal conditional exemption found in 40 CFR 266.305.

		It is not practical in most cases for laboratory workers to assess whether a given chemical, when added to a radioactive waste, creates a mixed waste.
		If the chemical is not specifically listed as a RCRA waste, we have to either apply a number of tests that characterize its ignitability (flash point), corrosivity (pH), reactivity, or toxicity, or apply knowledge of the processes that produced the waste to make a determination.
		The law requires the proper identification of mixed wastes and the Radioactive Waste Card is the means by which you communicate it to ORS.

	Comments on the DOE Advanced Mixed Waste Treatment Facility RCRA and TSCA Permit
		The supercompaction of transuranic waste increases the risk of a criticality in the facility (since the volume in which the plutonium is located is being reduced and the configuration is changing).
		Mixed waste incineration is categorically different than hazardous waste incineration in that radioactivity is converted into fine particles, which is undesirable from a health and environmental standpoint, by the very same process that is designed to destroy the hazardous constituents.
		Low-level mixed waste is ordinarily subject to the land disposal restrictions.
