(4) Any additional information specified in the section containing the approval; and
(5) For an approval which provides exceptions from regulatory requirements or prohibitions -
(i) Identification of any increased risk to safety or property that may result if the approval is granted, and specification of the measures that the applicant considers necessary or appropriate to address that risk; and
(ii) Substantiation, with applicable analyses or evaluations, if appropriate, demonstrating that the proposed activity will achieve a level of safety that is at least equal to that required by the regulation.
(c) For an approval with an expiration date, each application for renewal or modification must be filed in the same manner as an original application. If, at least 60 days before an existing approval expires the holder files an application for renewal that is complete and conforms to the requirements of this section, the approval will not expire until final administrative action on the application for renewal has been taken. Operation under an expired approval not filed within 60 days of the expiration date is prohibited. This paragraph does not limit the authority of the Associate Administrator to modify, suspend or terminate an approval under § 107.713.
