(a) Any person, applicant, trade union, association, etc. who does
not agree with action granting or denying a certificate (pursuant to
Secs. 520.406 and 520.505) may, within 60 days of that action or such
additional time as the Administrator may allow, file with the
Administrator a petition for review. The decision of the Administrator
becomes final unless such a written request is timely filed.
(b) Such requests should contain a statement of the additional
evidence which the person believes may materially affect the decision
and establish that there were reasonable grounds for failure to present
such evidence during the original certification process.
(c) If a request for reconsideration or review is granted, the
Administrator, to the extent it is deemed appropriate, may afford other
interested persons an opportunity to present data and views.
(d) The Administrator may conduct an investigation, which may
include a hearing, prior to taking any action pursuant to this part.
