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 Cornell generates many of these wastes during lab cleanouts or disposal of outdated chemicals.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.

5.2.1 Ignitability

• A liquid other than an aqueous solution containing less than 24 % alcohol by volume, having a flashpoint of less than 140°F.
• A non-liquid capable under standard temperature and pressure of causing fire through friction, spontaneous combustion, and when ignited, burns so vigorously and persistently that it creates a hazard.
• It is an ignitable compressed gas.
• It is an oxidizer.  

5.2.2 Corrosivity

• It is aqueous and has a pH of less than or equal to 2 or greater than or equal to 12.5.
• It is a liquid and corrodes steel at a rate greater than 0.250 inch per year.  

5.2.3 Reactivity

• It is normally unstable and readily undergoes violent change without detonating.
• It reacts violently or forms potentially explosive mixtures with water.
• When mixed with water, it generates toxic gases, vapors or fumes that present a danger to human health or the environment.
• It is a cyanide or sulfide bearing waste that can generate toxic gases vapors or fumes that present a danger to human health or the environment when exposed to pH conditions between 2 and 12.5.
• It can detonate or explode if subjected to a strong initiating source or if heated under confinement.
• It is readily capable of detonation or explosive decomposition or reaction at standard temperature and pressure.
• It is a forbidden explosive as defined in 49 CFR 173.

5.2.4 Toxicity

A solid waste exhibits the characteristic of toxicity if, using the EPA’s Toxicity Characteristic Leaching Procedure (TCLP) test method, the extract from a representative sample of the waste contains any of the contaminants listed in Table 1 of 40 CFR 261.24 at the concentration equal to or greater than the respective value given in the table. There are 40 contaminants listed in Table 1. Most of these are heavy metals, organic solvents, and pesticides.
