“Emergency,” as used in the McAteer-Petris Act, the Suisun Marsh Preservation Act, and in these regulations other than in the context of calling an emergency meeting means a sudden, unexpected situation that poses an immediate danger to life, health, property, or essential public services and that demands action by the Commission more quickly than the Commission's normal permit procedures would allow. A sudden, unexpected situation that poses an immediate danger to life, health, property, or essential public services may include, for example, an accident, sabotage, vandalism, fire, flood, earthquake, or soil or geologic movements.
