It is defined in 40 CFR part 273, by the United States Environmental Protection Agency but states may also have corollary regulations regarding these materials.
This is because we now know that some common items that have traditionally been thrown in your household's or small business' trash cannot be safely disposed in landfills. These common items are referred to as hazardous waste, and some of them as universal waste (u-waste). As of February 9, 2006, all u-waste items are banned from the trash. For additional information on u-waste, please check the Department of Toxics Substances Control (DTSC) Web site.
