Hazardous waste, under RCRA

Dredged materials subject to the requirement of a CWA permit are not considered hazardous wastes under RCRA. 

There are two major areas of overlap between MPRSA and RCRA. MPRSA prevents waste from an RCRA generator or TSDF from being deposited into the ocean, except in accordance with a separate MPRSA permit. In addition, dredged materials subject to the requirement of an MPRSA permit are not considered as hazardous wastes under RCRA.2... 

Mining overburden. After an area of a surface mine has been depleted, it is common practice to return to the mine the earth and rocks (overburden) that were removed to gain access to ore deposits. When the material is returned to the mine site, it is not a hazardous waste under RCRA. 

California criteria for defining hazardous wastes that are ignitable and reactive are identical to Federal criteria for hazardous wastes under RCRA defined at 40 CFR, Part 261. The California corrosivity criteria differ from the Federal criteria only in the addition of a pH test for nonaqueous wastes. 

The definition of solid waste in RCRA specifically excludes source, special nuclear, and byproduct materials as defined in AEA. Therefore, radioactive constituents of wastes that arise from operations of the nuclear fuel cycle are excluded from regulation as hazardous waste under RCRA. 

Finally, if high-level waste is considered to be hazardous waste under RCRA, requirements on construction, operation, and closure of a disposal facility, including the provision of a liner system, leachate collection and removal system, and leak detection system (see Section 4.2.2), would need to be addressed. Such requirements are impractical at a geologic repository for disposal of high-level waste... 

Transuranic Waste. Much of DOE s transuranic radioactive waste is classified as hazardous waste under RCRA and is managed as mixed waste (DOE, 1999b). Many transuranic wastes are hazardous due to the presence of toxic heavy metals or organic chemicals introduced into the waste during processing of plutonium. 

The term mixed waste refers mainly to waste that contains radionuclides regulated under AEA and hazardous chemical waste regulated under RCRA. Mixed waste is subject to dual regulation as a result of the exclusion of radioactive materials defined in AEA from regulation under RCRA. Dual regulation of mixed waste also extends to waste that contains NARM and hazardous chemicals, since NARM waste is not defined as a hazardous waste under RCRA, and to... 

Elimination of source-based waste classifications would also have some impact on classification and management of hazardous chemical wastes. For example, the identification of some listed hazardous wastes under RCRA based on the source of the waste (the F and K lists) and the distinction between hazardous wastes regulated under RCRA and those regulated under TSCA would be eliminated. 

The EPA regulates wastes under the Resource Conservation and Recovery Act (RCRA). EPA issues a list of materials that are considered hazardous. However, RCRA applies to certain flammable, corrosive, reactive, or toxic wastes, even if they are not on the list. Therefore, some other pesticides could be regulated hazardous wastes under RCRA. States and tribes often have their own hazardous waste laws, which may be more stringent than RCRA. Contact your State or tribal authority for applicable requirements. ... 

Wastes include rinsed containers, excess pesticides, pesticide dilutions and rinse and wash water that contain a hsted chemical and cannot be used. Triple-rinsed pesticide containers are not considered hazardous waste under RCRA and can be disposed of in sanitary landfills. 

Spent caustic (3800 tons/year) is sent off-site for recovery of remaining caustic value and naphthenic acids. Most catalysts are recycled for recovery of additional activity or metals. Spent cracking catalyst (6(K) tons/year) is sent to Amoco s Whiting, Indiana, refinery for use as equilibrium catalyst. Spent ultraforming catalyst is returned to metals reclaimers to recover platinum for reuse in new catalyst. Spent desulfurization catalyst and polymer catalyst are nonhazardous and are buried in an on-site landfill. Sludges from the oil/water separator are a listed hazardous waste under RCRA regulations. They are combined with other solid wastes, such... 

As discussed in the next section, certain sodium silicate liquids which do not meet DOT criteria for a corrosive liquid are hazardous waste under RCRA when discarded. These are DOT-regulated as ORM-E (43). Similarly, the dry blends which are identified in the next Section as EPA hazardous substances because of their sodium hydroxide content are DOT-regulated as ORM-E, if they contain the reportable quantity of 1,000 lb. NaOH in a single package or bulk container. 

If a highly alkaline sodium silicate waste is classified as a hazardous waste under RCRA, it is also a hazardous substance under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA or Superfund Act), The law s reporting requirements would apply to any release into the environment. This is also true for the previously mentioned sodium orthosilicate products which are EPA hazardous substances, since they are physical mixtures containing sodium hydroxide. For sodium hydroxide the reportable quantity remains... 

High levels of chloroform—a. listed hazardous waste under RCRA— were observed in EDS cleaning solutions from the RMA tests (Appendix C, Table C-1). The source appears to be the particulartypeof lubricant/sealant used to seal joints. The chloroform is therefore not a necessary constituent of the waste stream and could be eliminated by using a different formulation of sealant/lubricant. 

In all states, the EDS neutralents could be considered characteristic hazardous wastes under RCRA. With some exceptions, a hazardous waste may only be treated, stored, or disposed of in a RCRA-permitted TSDF. In addition, any treatment technology must meet RCRA requirements, such as the Land Disposal Restrictions (LDRs) (40 CFR 268). In accordance with the LDRs, wastes must meet certain treatment standards prior to land disposal. These restrictions provide for additional protection of human health and the environment, but they add considerably to the cost and time required to treat and dispose of the waste stream. Other standards must also be met, such as those associated with treatment facihty operation and closure. 

Beyond solid wastes, a chemical substance may be labeled as a "hazardous waste" under RCRA if it is listed as a hazardous waste by EPA or if it is determined to be a characteristic "hazardous waste" that exhibits high ignitability, corrosivity, reactivity, or toxicity. Once a material is labeled as a hazardous waste, the material is tracked and permitted at all stages of the manufacturing, use, and disposal process. Generators of hazardous wastes are required to keep detailed records from cradle to grave of the substance to ensure unintended releases and environmental contamination do not... 

In Jffiy 2013, EPA issued a final rule that exempts most solvent-contaminated wipes from being considered hazardous wastes under RCRA. A solvent -contaminated wipe is a wipe (i.e., shop towel, rag, pad, or swab made of wood pulp, fabric, cotton, polyester blends, or other material) that would be considered hazardous waste either because it is listed in the hazardous waste regulations, or because it exhibits a characteristic of ignitability. Note that under the definition of solvent-contaminated wipe, the wipe cannot be contaminated... 

Hazardous waste is defined under the Resource Conservation and Recovery Act (RCRA) as a solid waste (or combination of solid wastes) which, because of its quantity, concentration, or physical, chemical, or infectious characteristics, may (1) cause or contribute to an increase in mortality or an increase in serious irreversible, or incapacitating illness or (2) pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, disposed of, or otherwise managed. In addition, under RCRA, EPA establishes four characteristics that will determine whether a substance is considered hazardous, including ignitability, corrosiveness, reactivity, and toxicity. Any solid waste that exhibits one or more of these characteristics is classified as a hazardous waste under RCRA and, in turn, as a hazardous substance mider Superfiind. 

Because neutralent waste streams from the RRS and MMD are expected to be classified as hazardous wastes under RCRA, the Army had planned to ship them to a permitted hazardous waste incinerator for final disposal. However, because the incineration of chemical agents has aroused considerable opposition among public interest groups, and because this opposition may be extended to the incineration of neutralents, the Army is also investigating alternative (nonincineration) technologies for disposing of neutralents. 

EPA does not explicitly say which wastes are covered by its use of the term hazard wastes. An assumption can be made that since the report deals within the context of RCRA and was mandated under RCRA that EPA considers waste minimization to cover only those solid wastes regulated as hazardous waste under RCRA. 

The Florida Department of Environmental Protection (DEP) emphasizes that CTRs are hazardous waste under the Resource Conservation and Recovery Act (RCRA) when discarded into landfills or waste incinerators. Under the DEP s interpretation of RCRA hazardous waste regulations [36], CTRs are considered as materials, rather than wastes, when reused as a substitute for commercial purposes, i.e., when utilized to manufacture new CRTs, or as a fluxing agent at a secondary lead smelter. Only CTRs disposed in landfills or incinerated are regulated as hazardous waste under RCRA.
