(3) The views of the certificate holder;
(4) The views of the airport users; and
(5) Any other factors bearing on the
matter of which the Administrator is aware.
(d) When the Administrator determines
that a wildlife hazard management plan is needed, the certificate holder

basis. The plan shall --
(1) Be submitted to, and approved by,
the Administrator prior to implementation; and
(2) Provide measures to alleviate or
eliminate wildlife hazards to air carrier operations.
(e) The plan shall include at least the
(1) The persons who have authority and

should be reevaluated.
(7) A training program to provide

(f) Notwithstanding the other
requirements of this section, each certificate holder shall take immediate
