(a) A certificate shall be valid under the terms set forth in the
certificate for a period to be designated by the Administrator or his
authorized representative. Application for renewal of any certificate
shall be filed in the same manner as an original application under this
part.
(b) No effective certificate shall expire until action on an
application for renewal shall have been finally determined, provided
that such application has been properly executed in accordance with the
requirements, and filed not less than 15 nor more than 30 days prior to
the expiration date. A final determination means either the granting of
or initial denial of the application for renewal of a certificate, or
withdrawal of the application. A ``properly executed'' application is
one which contains the complete information required on the form.
