5.0 SEEDING OPERATIONS

The responsibility for day to day seeding decisions
rests with the licensee, Project Director. He will base his
decisions on priority guidelines set by the Policy Board and
on meteorological conditions. The basic meteorological crit-
eria used to initiate or suspend seeding operations are out-
lined in the following paragraphs.

5.1 Seeding Criteria

The criteria for selecting suitable cloud systems
for seeding will be based on an assessment of multiple1meteor-
ological parameters. Every weather system will be examined for
seeding potential. Seeding will be initiated on the basis of
the general criteria listed in Table I.

5.2 Suspension Criteria

Seeding to increase rain will not be initiated
or will be suspended when excessive rain is likely to occur.

The licensee, Project Director, will take cogni-
zance of the sociological aspects of seeding when severe
storms are forecast or already exist. Hail suppression opera-
tions will be conducted when beneficial results appear attain-
able and when flying safety is not jeopardized.

Rain augmentation operations shall be suspended
when soil moisture, as determined by the pOlicy Board, is
adequate. Seeding shall also be suspended at any time the
policy Board determines that weather modification activities
are not considered beneficial to a particular community.
