Many types of businesses produce hazardous waste.
Some are small companies such as dry cleaners, auto repair shops, hospitals, and photo processing centers. Others are larger firms which may generate large quantities of hazardous waste, such as chemical manufacturers, electroplating companies, and petroleum refineries. RCRA waste is solid waste assigned a federal hazardous waste code and regulated by RCRA either because it was managed subject to RCRA permitting standards or because it was shipped subject to RCRA hazardous transportation requirements. EPA has a list of specific hazardous wastes, defined by 504 different waste codes. Not all hazardous waste is RCRA waste.
