5.1.1 F-Listed Waste

These wastes are known as “Non-Specific Source Wastes.” They are mostly spent solvents and wastewaters. Many of Cornell’s laboratories generate these spent solvent wastes. 

5.1.2 K-Listed Waste

These wastes are " Specific Source Wastes". Most are from industrial process wastes and are very specific to a particular industrial process. For example; K050…Heat exchanger bundle cleaning sludge from the petroleum refining industry. Cornell does not generate any K-Listed Waste.    

5.1.3 U and P Listed Waste

U and P listed wastes are discarded commercial chemical products, off-specification species, container residues, and spill residues thereof. In general, they are unused materials containing only one active ingredient. Cornell generates many of these wastes during lab cleanouts or disposal of outdated chemicals.

The main differences between U-Listed and P-Listed waste is that the P-Listed wastes are acutely toxic and the empty containers which held their material must be triple rinsed, and the rinsate collected and shipped as hazardous waste. Alternatively, using a CU Hazardous Waste label, manage the empty bottle as P-listed hazardous waste ensuring the listed chemical is identified on the label.  The storage time requirements for generators are more stringent when storing P-Listed wastes. 

5.1.4 Polychlorinated Biphenyls (PCBs)

The DEC list for PCB wastes includes various PCB’s, PCB transformers, articles, and other PCB wastes. They are not EPA listed hazardous waste but are regulated by New York State as hazardous waste in 6 NYCRR 371.4.
