California Department of Toxic Substances Control (DTSC) Mission Statement
The Department's mission is to restore, protect and enhance the environment, to ensure public health,
environmental quality and economic vitality, by regulating hazardous waste, conducting and overseeing
cleanups, and developing and promoting pollution prevention.
Overview of DTSC
Each year, Californians generate two million tons of hazardous waste. One hundred thousand privately-
and publicly-owned facilities generate one or more of the 800-plus wastes considered hazardous under
California law. Properly handling these wastes avoids threats to public health and degradation of the environment.
DTSC regulates hazardous waste, cleans-up existing
contamination, and looks for ways to reduce the hazardous waste produced in California. Almost 1,000
scientists, engineers, and specialized support staff make sure that companies and individuals handle,
transport, store, treat, dispose of, and clean-up hazardous wastes appropriately. Through these measures,
DTSC contributes to greater safety for all Californians, and less hazardous waste reaches the environment.
