The mission of DTSC’s Emergency Response Unit (ERU) is to provide statewide response to actual and potential releases of hazardous substances that pose an acute threat to public health and/or the environment, including clandestine drug labs. The ERU interacts with a number of other state, federal and local agencies in carrying out these emergency response activities.
The Emergency Response Unit responds statewide to requests for DTSC assistance for emergency removals from illegal/clandestine drug labs and other Hazardous Materials (HazMat) emergencies. Requests for assistance are handled by the Emergency Response Duty Officers.
