A waste is basically any discarded material. By law hazardous waste is defined as a waste, or combination of wastes, that because of its quality, concentration, physical, chemical or infectious characteristics may cause or significantly contribute to an increase in serious irreversible, or incapacitating reversible illness or pose a substantial present or potential hazard to human health, safety or welfare or to the environment when improperly treated, stored, transported, used or disposed of or otherwise managed.
A hazardous waste is:
Hazardous Waste can be identified by consulting 4 CFR 261. The codes not only represent the ingredients of the waste, but indicate the process generating the waste. Each hazardous waste has a particular alphanumeric code based on its ingredients and process. Wastes are categorized by the following:
Four chemical lists exist (F, K, U, and P) of waste streams that possess hazardous properties and are subject to hazardous waste regulations.
"K-Listed" waste are those generated from a specific process, and therefore are not applicable to Alfred University.
"F-Listed" wastes are hazardous wastes from nonspecific sources. Although there are 39 listings (F001-F039), the most common F-listed wastes generated on campus are F001-F005.
Some common examples of "F-listed" hazardous wastes include:
"U-Listed" wastes are regulated as toxic, reactive, ignitable, or corrosive waste.
"P-Listed" wastes are regulated as acutely hazardous wastes. An acutely hazardous waste poses immediate and serious health risks to both the environment and humans.
Both "U-Listed" and "P-Listed" codes are assigned to chemicals that are discarded commercial chemical products, off-specification species, and container residues. The EPA and DEC also regulate any residue or contaminated soil, water or other debris resulting from the cleanup of a spill involving a U or P-listed chemical as hazardous waste. It is EH&S policy that any mixture of chemicals that contain ANY concentration of U or P-listed chemicals is considered to be hazardous waste and must be disposed of through the hazardous waste management program. The U and P lists of chemicals can be found at the appropriately labeled tab in this document.
Four categories of chemical wastes that under certain conditions or concentrations possess hazardous properties that are subject to hazardous waste regulations.
These characteristic properties are:
Many states choose to regulate additional materials not covered in the Federal regulations. New York State regulates Polychlorinated Biphenyls (PCBs).
PCBs and PCB contaminated materials are regulated by the DEC as hazardous waste. PCBs and all waste chemicals and contaminated debris containing 50 PPM (parts per million) or greater of PCBs are a New York State listed hazardous waste. Oils in or from electrical equipment whose PCB concentration is unknown or not otherwise clearly marked as "No PCBs", must be assumed to contain between 50 and 500 ppm of PCBs and must be disposed of through the hazardous waste management program.
Due to the high cost for disposal of PCB waste, it is very important to keep PCB waste clearly identified and separated from other wastes. If PCB waste is added to a container of non-PCB waste, the resulting mixture will have to be treated as PCB waste. Please make every attempt to minimize the amount of PCB waste that you generate.
The division of Ceramic Art has developed a system which identifies materials that require hazardous waste disposal.
All materials stocked by the Claystore that are regulated by federal, state, or local agencies are labeled with this yellow sticker.
This sticker is also applied to mixtures containing these regulated materials.
If a solid waste does not contain any of the four listed wastes (F, K, U, P), it still may be a hazardous waste due to the characteristics of a sample of the waste. It may exhibit ignitability, corrosivity, reactivity, and/or toxicity.
