Air Indoor Resources - Hazardous Waste Management
Listed” hazardous waste categories have different EPA waste numbers/codes represented by a letter and three digits. The first is hazardous waste from the “Non-Specific Source Wastes” code represented by the letter “F” (known as “F-Listed” wastes). Other categories include “K,” “P,” and “U” listed wastes (40 CFR 261.31-.33). The EPA Hazardous Waste web site is very comprehensive and covers all of the wastes explained in this section.
Following are the categories and waste numbers/codes for listed hazardous wastes:
- Non-Specific Sources wastes are given the
waste code “F” .
- Listed Solvents, F001 to F005, are wastes from common manufacturing processes such as halogenated solvents used in cleaning and degreasing operations.
- Listed Electroplating/Metal Finishing Wastes, F006 to F019, include processes that generate cyanide.
- Other Non-Specific Wastes, F020 to F026, are wastes that are generated from manufacturing of chlorine based compounds.
- Specific Sources wastes are given the classification “K” and identify industries that generate specific source wastes from their manufacturing processes such as wood preservation, petroleum refineries, and pesticide manufacturing.
- Discarded Commercial Chemical Products are given “P” or “U” classifications and are considered acute hazards. These categories include unused commercial chemical products as well as pesticides and some pharmaceutical products that become a hazardous waste when declared for disposal. Acute Hazards identifies hazards that are considered lethal to humans in low doses as discovered through animal testing.
Examples of waste numbers/codes for “F Listed Wastes” are:
- F001 are spent halogenated (usually chlorinated) solvents used in degreasing or automotive parts washers such as tricholorethylene, tetrachloroethylene, methylene chloride (paint stripper), toluene, or carbon tetrachloride;
- F002 are spent halogenated solvents not used for degreasing, many the same as those cited for F001.
- F003 are spent halogen ignitable solvents such as xylene, acetone, methanol and methyl isobutyl ketone;
- F004 are spent non-halogenated solvents such as cresols and nitrobenzene, which are toxic;
- F005 are spent non-halogenated solvents such as toluene, methyl ethyl ketone, and benzene, which are all toxic and ignitable.
Acutely toxic F-Listed wastes are F020-F023; F026 from wastewater and spent carbon from hydrogen chloride; and F027 from discarded unused formulations containing tri-, tetra-, or pentachlorophenol.
Wastes that are exempt from RCRA, not listed or characteristic, and do not contain PCBs over 50 ppm are considered non-hazardous. If the waste contains any of the previously mentioned constituents, it is a hazardous waste.
Criteria for Identifying the Characteristics of Hazardous Waste and Listed Hazardous Waste” is found in Title 40, Code of Federal Regulations, Parts 261.10 through 261.35 and Appendices. All waste evaluation records, whether the substance was found hazardous or not, should be kept on-site for three years. EPA 40 CFR Part 260 through 265 outlines the EPA’s hazardous waste management rules, wastes, and threshold concentrations.
