Non-specific Sources

Listed hazardous wastes from non-specific sources have waste codes that begin with an “F” followed by a three-digit number. These wastes are not based on a specific industry process that generated the waste, or on the concentration of the chemicals present in the waste. Many industries may generate “F listed” wastes; for instance, a dry cleaner, a circuit board manufacturer or an autobody shop may generate solvent wastes.

Some non-specific sources are:

Spent solvent wastes (F001 – F005)
Electroplating and metal finishing operations wastes (F006 – F012, F019)
Dioxin-bearing wastes (F020 – F023, F026 – F028)
Chlorinated aliphatic hydrocarbons production wastes (F024, F025)
Wood preserving wastes (F032, F034, and F035)
Petroleum refinery wastewater treatment sludges (F037 and F038)
Multisource leachate (F039)

Example: Spent Solvent Waste (F001)

For F001, the federal code reads:

“…the following spent halogenated solvents used in degreasing: Tetrachloroethylene, trichloroethylene, methylene chloride, 1,1,1-trichloroethane, carbon tetrachloride, and chlorinated fluorocarbons; all spent solvent mixtures/blends used in degreasing containing, before use, a total of ten percent or more (by volume) of one or more of the above halogenated solvents or those solvents listed in F002, F004, and F005; and still bottoms from the recovery of these spent solvents and spent solvent mixtures;”

Let’s look at this a little closer to determine what it is really telling us. First, identify the key terms:

“…the following spent halogenated solvents used in degreasing: Tetrachloroethylene, trichloroethylene, methylene chloride, 1,1,1-trichloroethane, carbon tetrachloride, and chlorinated fluorocarbons; all spent solvent mixtures/blends used in degreasing containing, before use, a total of ten percent or more (by volume) of one or more of the above halogenated solvents or those solvents listed in F002, F004, and F005; and still bottoms from the recovery of these spent solvents and spent solvent mixtures;”
