(a) The procedures should provide that projected
concentrations, collective exposure, and/or
exposure rates be projected at receptor
locations (e.g., facility, boundary, or site
boundary) and in such units to facilitate
comparison with an EAL or a protective action
(b) For the purposes of determining appropriate
protective actions, the procedures should
provide that the models and methods have the
capability to project integrated consequences
based on current and predicted future
conditions of release and dispersion.
Procedures for refining emergency class and
determining protective actions should consider
consequence assessment results. A facility-specific
EAL set should be revised if necessary to be
consistent with consequence assessment results.
The plan and procedures for consequence assessment
should be coordinated with those of offsite officials, to
ensure mutual understanding of the methods used and
provide a basis for confirmation or comparison of
Calculational models and measurement methods
should be consistent, or else the differences
mutually understood, so as to avoid confusion or
delay in determining protective actions.
There should be a protocol for sharing and
transmitting consequence assessment information
among response organizations, including units of
measure to be used for describing the hazard.
