Four operating modes have been established for the Multi-Agency Coordination System.
The decision to change modes will
be made by a MACS Conference Call, or collectively by the Cal OES Southern
California Fire & Rescue Deputy Chief, CAL Fire Region Operations Chief, DOI Coordinator and USFS GACC Manager or designees.
Modes 1 and 2 reflect a non-critical regional situation. In general, in modes
1 and 2 there are no major multiple incidents which would require
extended use of multi-agency resources. Most of the MACS coordination
points will be operational on a 24 hour day basis in modes 1 and
2, although several points will make alternate arrangements for
contacts and responsibilities during night time and /or weekends.
The basic distinction between Modes 1 and 2 is seasonal.
Mode 3 is called to
reflect a serious situation or the potential for a serious situation.
A serious situation could be a high potential incident which involves
the use of Multi-Agency resources. Generally, a mode 3 condition
would prevail when one to three such incidents were ocurring simultaneously
. A mode 3 could also be called if the potential for an emergency
situation would warrant. For example, severe weather conditions
or a tsunami warning could be sufficient to initaite a mode 3. Another
condition which could warrant a mode 3 would be a major commitment
of fire suppression resources to out-of-region incidents.
Mode 4 signifies the
existence of an all-out regional effort where resource use priorities
requires a concerted multi-agency coordination effort. Under mode
4, the MACS/OCC command conference room would be established as
a regional GHQ. Agency represenatives to the MACS/OCC GHQ under
mode 4 should be fully authorized to speak and commit for their
