(a) Final determinations. Within 30 days of receiving the Secretary's report and record, the Committee shall grant an exemption from the requirements of section 7(a)(2) of the Act for an agency action if, by a vote in which at least five of its members concur:

(1) It determines that based on the report to the Secretary, the record of the hearing held under § 452.05, and on such other testimony or evidence as it may receive:

(i) There are no reasonable and prudent alternatives to the proposed action;

(ii) The benefits of such action clearly outweigh the benefits of alternative courses of action consistent with conserving the species or its critical habitat, and such action is in the public interest;

(iii) The action is of regional or national significance; and

(iv) Neither the Federal agency concerned nor the exemption applicant made any irreversible or irretrievable commitment of resources prohibited by section 7(d) of the Act; and,

(2) It establishes such reasonable mitigation and enhancement measures, including, but not limited to, live propagation, transplantation, and habitat acquisition and improvement, as are necessary and appropriate to minimize the adverse effects of the proposed action upon the endangered species, threatened species, or critical habitat concerned. Any required mitigation and enhancement measures shall be carried out and paid for by the exemption applicant.

(b) Decision and order. The Committee's final determinations shall be documented in a written decision. If the Committee determines that an exemption should be granted, the Committee shall issue an order granting the exemption and specifying required mitigation and enhancement measures. The Committee shall publish its decision and order in the Federal Register as soon as practicable.

(c) Permanent exemptions. Under section 7(h)(2) of the Act, an exemption granted by the Committee shall constitute a permanent exemption with respect to all endangered or threatened species for the purposes of completing such agency action—

(1) Regardless of whether the species was identified in the biological assessment, and

(2) Only if a biological assessment has been conducted under section 7(c) of the Act with respect to such agency action. Notwithstanding the foregoing, an exemption shall not be permanent if—

(i) The Secretary finds, based on the best scientific and commercial data available, that such exemption would result in the extinction of a species that was not the subject of consultation under section 7(a)(2) of the Act or was not identified in any biological assessment conducted under section 7(c) of the Act, and

(ii) The Committee determines within 60 days after the date of the Secretary's finding that the exemption should not be permanent.

(d) Finding by the Secretary of Defense. If the Secretary of Defense finds in writing that an exemption for the agency action is necessary for reasons of national security, the Committee shall grant the exemption notwithstanding any other provision in this part.
