California Identification (ID) Numbers
DTSC issues permanent California ID numbers to generators, transporters and disposal facilities not regulated by the U.S. Environmental Protection Agency (U.S. EPA) for the purpose of tracking hazardous waste. California ID numbers are site-specific and owner-specific. The ID number enables regulators to track the waste from its origin to the final disposal (“cradle to grave”). An ID number identifies each handler of hazardous waste on a hazardous waste manifest and other purposes. Some activities are exempt from having an ID number. DTSC's contractor Tetra Tech Inc., issues federal ID numbers.
