Consequence assessment procedures should include
descriptions of methods and instrumentation used
to determine the status of affected systems, release
parameters, and environmental conditions. These
methods and instrumentation should be specific to
the point of release, pathway, and material of
concern. The procedures should:
(a) include methods for determining potential
source terms (e.g., radioactive material
inventory in process streams or quantities of
toxic materials in storage tanks).
(b) include methods for determining the magnitude
of the release of hazardous materials (e.g.,
effluent monitors, process parameters, leak rate
indicators, or inventory loss calculations).
(c) address the relationships between effluent
monitor readings and consequences at specific
onsite and offsite locations.
(1) The procedures should identify instru-
mentation that does not directly measure
effluent but which can provide the basis for
estimates of material being released.
(2) The procedures should document the
correlation between instrument readings
and quantities of interest.
(d) The procedures should describe methods to
acquire and use meteorological data that are
commensurate with facility hazards and
potential emergencies. The meteorological
program required for consequence assessment
should be based on an extension of the existing
environmental program (required by DOE
Order 4500.1) at each facility.
