IMPERIAL COUNTY AIR POLLUTION CONTROL DISTRICT
RULE 604 - DIVISION OF RESPONSIBILITY FOR ABATEMENT ACTION
(Last revised or adopted prior to October 15, 1979)
- Prediction of Episode Conditions: The Air Resources Board will provide advisory notices of probable
episodes. These notices will include air quality prediction based upon analysis of meteorological and ambient air
quality data. The Imperial County Air Pollution Control District may supplement this information with data from
their own facilities or from contract services.
- Stage 1 (Health Advisory - Alert): The Air Pollution Control Officer shall notify persons with special
health problems to take precautions against exposures. Schools shall be notified by the Air Pollution Control Officer
so they can curtail students participation in strenuous activities. Abatement action for this stage will be voluntary.
- Stage 2 (Warning): The Air Pollution Control Officer shall implement both voluntary and mandatory abatement
- Stage 3 (Emergency): The Air Pollution Control Officer shall take all authorized actions to abate the
emergency. If further abatement action is necessary, the Air Pollution Control Board may request the Governor to
take action. (The Governor may take action in accordance with the Emergency Services Act.) The Air Resources Board
should be consulted prior to submitting this request. If the Governor invokes the provisions of the Act, the Office
of Emergency Services (OES) will implement the appropriate portion of the State Peacetime Emergency Plan, with
the local district and the Air Resources Board assisting in the control action.
- Termination: The Air Pollution Control Officer shall terminate Stage 1, Stage 2, and Stage 3 using the
episode termination criteria. If the emergency stage is declared by the Governor it can only be terminated by the
Governor or his authorized representative.
