Emergency Response Program
The mission of DTSC's Emergency Response Program (ERP) 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 ERP interacts with a number of other state, federal and local agencies in carrying out these emergency response activities.
The Emergency Response Program responds statewide to calls requesting DTSC assistance for emergency removals from illegal/clandestine drug labs and other Hazardous Materials (HazMat) emergencies. Requests for assistance are handled by the ERP's Emergency Response Duty Officers.
