TCLP: Toxic as defined through application of a laboratory test procedure called the Toxicity Characteristic Leaching Procedure (TCLP – U.S. EPA Test Method 1311). The TCLP identifies wastes (as hazardous) that may leach hazardous concentrations of toxic substances into the environment. The result of the TCLP test is compared to the Regulatory Level (RL) in the table in subsection 66261.24 (a) (1) of the hazardous waste regulations. This criterion does not apply to wastes that are excluded from regulation under the Resource Conservation and Recovery Act.
What is hazardous waste?

What is a Hazardous Waste?
According to the EPA, “Simply defined, a hazardous waste is a waste with properties that make it dangerous or capable of having a harmful effect on human health or the environment.” Hazardous waste also includes different physical forms, including: solids, liquids, and gases.
What does the EPA require of waste generators?
The EPA then requires waste generators to check if they’re producing waste with features that classify it as “hazardous.”
What is a regulated hazardous waste?
The EPA has created a regulatory hazardous waste definition. It has defined various substances that have been scientifically proven to be hazardous. The EPA has also created objective requirements that allow for a particular material to be regulated as “hazardous waste.”.
Why is recycling hazardous waste important?
It’s critical to ensure proper storage of the materials. This can prevent events like leaks, spills, fires, and contamination of drinking water and soil.
How much waste does the world produce per second?

Are commercial chemical products (CCPs) solid waste when burned as a fuel for energy recovery?
The manner in which a secondary material is recycled determines whether the material is a solid waste and, therefore, potentially regulated as a hazardous waste. The type of recycling called "burning for energy recovery" includes two activities: burning hazardous waste for energy recovery and using waste to produce a fuel ( Section 261.2 (c) (2) and 50 FR 614, 630; January 4, 1985 ). All secondary materials that are burned for energy recovery or used to produce a fuel or otherwise contained in fuels are solid wastes (Section 261.2). However, recycled CCPs that are themselves fuels are not considered solid wastes when burned for energy recovery since burning as a fuel is consistent with the product's intended use (Section 261.2 (c) (2) (ii)). For example, off-specification jet fuel is not a solid waste when it is burned for energy recovery because it is itself a fuel.
What is the difference between a by-product and a co-product?
A by-product is a material that is not a primary product of a production process and is not solely or separately produced by the production process, whereas a co-product is produced for the general public's use and is ordinarily used in the form produced by the process ( Section 261.1 (c) (3) ).
How is a secondary material regulated if it is recycled by direct use or reuse without prior reclamation?
Direct use or reuse of a secondary material without prior reclamation is a form of recycling . Section 261.2 (e) provides exclusions from the definition of solid waste for materials that are directly used or reused without prior reclamation in one of the following ways:
What is the manufacturing process tank exclusion and when does it apply to a wastestream?
A hazardous waste that is generated in a product or raw material storage tank, a product or raw material transport vessel, a product or raw material pipeline, or in a manufacturing process unit or an associated non-waste-treatment-manufacturing unit, is not subject to regulation under 40 CFR Parts 262 through 265, 268, 270, 271, and 124 or the notification requirements of Section 3010 of RCRA until it exits the unit in which it was generated, unless the unit is a surface impoundment, or unless the hazardous waste remains in the unit more than 90 days after the unit ceases to be operated for manufacturing, or for storage or transportation of product or raw materials ( Section 261.4 (c) ). If the waste were not generated in the unit, it would not qualify for the exclusion.
Does the household hazardous waste (HHW) exclusion extend to HHW collected in HHW collection programs?
The HHW exclusion extends to household wastes accumulated in quantities that would otherwise be regulated or when transported, stored, treated, disposed, recovered, or reused at collection centers or during collection programs. However, if household wastes are mixed with regulated hazardous waste from commercial or industrial sources, the resulting mixture could be subject to RCRA regulation and the collection center could be a hazardous waste generator (Memo, Porter to Directors, Regions 1-10; November 1, 1988 RCRA Online #11377 ). If a collection center does not wish to segregate HHW from other hazardous waste, or if they wish to adopt the most environmentally conservative approach, they may handle all of the waste as hazardous waste and count it all towards their generator status (Memo, Helms to Toro; July 12, 1996 RCRA Online #11958 ).
Is a discarded freon cylinder regulated as hazardous waste?
Freon is considered a hazardous waste when used as a refrigerant or blowing agent if the waste generated exhibits a characteristic of a hazardous waste. However, to promote recycling and discourage the practice of venting used chlorofluorocarbon (CFC) refrigerants into the atmosphere in order to avoid Subtitle C regulation, the Agency has provided an exclusion for CFCs that are recycled (i.e., reclaimed for reuse) ( 56 FR 5910; February 13, 1991 (OSW-FR-91-005) ). Used CFCs from totally enclosed heat transfer equipment (i.e., air conditioning and refrigeration systems) are not hazardous wastes when recycled, as long as the refrigerant is reclaimed for further use ( 40 CFR section 261.4 (b) (12) ). However, filters from the chlorofluorocarbon (CFC) refrigerant reclamation process do not qualify for the Section 261.4 (b) (12) exclusion.
What is a CCP?

A commercial chemical product (CCP) is an unused chemical intermediate, off-specification variant, or spill or container residues as defined in Section 261.33 ( 50 FR 614, 618; January 4, 1985 ). CCPs include all types of unused chemical products, ...
How long can a generator accumulate hazardous waste?
The length of time a generator is allowed to accumulate hazardous waste on site will vary depending on how much hazardous waste it generates in a calendar month. A large quantity generator (LQG) can accumulate hazardous waste on site for up to 90 days in specified units without obtaining a storage permit or interim status, provided the facility complies with Part 262 management standards for specific units ( section 262.17 ). A small quantity generator (SQG) can accumulate up to 6,000 kg of hazardous waste for 180 days or less in tanks or containers if the facility complies with the modified standards in section 262.16. An SQG can accumulate hazardous waste for up to 270 days if the treatment, storage, or disposal facility is 200 miles or more away ( sections 262.16 (d) ). Generators can receive a 30-day extension for accumulation of hazardous waste if uncontrollable and unforeseen circumstances cause them to accumulate waste on site for longer than the allowed time period. Such an extension may be granted by a Regional Administrator or authorized state on a case-by-case basis (sections 262.16 (d) and 262.17 (b) ).
What is point of generation for hazardous waste?
The point of generation for hazardous waste is when it is first produced or first becomes subject to hazardous waste regulations, not when a generator first receives waste analysis results. The hazardous waste generator regulations in 40 CFR part 262 apply as soon as waste is generated, and the accumulation period applies either as soon as the waste is generated or when waste is removed from the satellite accumulation area (Memo, Lowrance to Axtell; April 21, 1989 ( RCRA Online #11424 (2 pp, 34 K, About PDF) ). If a generator is unsure if the waste being tested is a hazardous waste, the generator must manage it as hazardous waste and label the containers with the potential hazard of the contents (e.g., ignitable, toxic, reactive, corrosive), the words “hazardous waste” (they could also use “hazardous waste pending analysis” to make it clear that testing is not yet complete), and the date upon which accumulation began. That way the generator will remain in compliance with the part 262 labeling requirements if the waste is determined to be hazardous. If the waste is determined to be non-hazardous, the generator can remove the hazardous waste labels at that point.
What are the requirements for hazardous waste generators?
Hazardous waste generators must certify compliance with waste minimization requirements in RCRA section 1003 (b) when preparing a hazardous waste manifest. Large quantity generators must certify that they have a program in place to reduce the volume and toxicity of the hazardous waste they generate; small quantity generators must certify that they have made a good faith effort to minimize their waste generation. Generators should include the following six basic elements in their waste minimization program: top management support, characterization of waste generation and waste management costs, periodic waste minimization assessments, appropriate cost allocation, encouragement of technology transfer, and program implementation and evaluation (58 FR 31114, May 28, 1993).
How long does it take for hazardous waste to be removed from a tank?
The LQG must also mark hazardous waste accumulation tanks with the date upon which the hazardous waste accumulation period begins or use inventory logs, monitoring equipment, or other records to be able to demonstrate that the waste is removed from the tank within 90 days of generation.
How much hazardous waste can a generator generate?
A generator may accumulate up to fifty-five gallons of hazardous waste and/or one quart of liquid acute hazardous waste or one (1) kg of solid acute hazardous waste at each satellite accumulation area (SAA) . The preamble of the Hazardous Waste Generator Improvements rule (81 FR 85732) includes a discussion about and examples of what EPA means by “under the control of the operator.” For example, EPA would consider waste to be “under the control of the operator” if the operator controls access to an area, building, or room in which the SAA is located, such as with entry by access card, key or lock box. Another example is if the operator accumulates waste in a locked cabinet and controlled access to the key, even if the cabinet is stored inside a room to which access is not controlled. See pages 85767–8 of the preamble for the full discussion.
What is a large quantity generator?
Large quantity generators (LQGs) and small quantity generators (SQGs) can treat hazardous waste in tanks, containers, or containment buildings without obtaining a permit or interim status provided they comply with the requirements in section 262.15–17, which include references to unit-specific requirements in Part 265 (51 FR 10146, 10168; March 24, 1986). For example, in order to treat hazardous waste on site for less than 90 days in accordance with section 262.16 and section 262.17, a small quantity generator must place the waste in containers in compliance with section 262.16 (b) (2), tanks in compliance with section 262.16 (b) (3), or containment buildings in compliance with section 262.16 (b) (5). A large quantity generator must comply with section 262.17 (a) ( (1) for containers, section 262.17 (a) (2) for tanks, or section 262.17 (a) (4) for containment buildings. LQGs are also subject to any applicable air emissions requirements at 40 CFR part 265 subparts AA, BB, and CC.
How much hazardous waste is a VSQG?
The regulations do not specify a separate generation limit for acute hazardous waste specific to SQGs. A person generating less than or equal to one kilogram of a cute hazardous waste per calendar month is a VSQG. A person generating more than one kilogram of acute hazardous waste in a calendar month is an LQG.
