An EPA ID # is a registration number provided by a delegated State Agency with the approval of the Federal Environmental Protection Agency. The ID # is assigned to a physical location. The business and the property owners are associated with the registration. The ID # registers a physical location and identifies it as a place where hazardous waste is generated. Furthermore, the location identifies the volume and type of hazardous waste generated at that location. The volume and type of hazardous waste will place the generator into their generator classification, conditionally exempt small quantity generator (CESQG), small quantity generator (SQG) or large quantity generator (LQG).
Transportation businesses that handle hazardous waste are also required to register their location and obtain and EPA ID #.
