(2) APPLICATION FOR OPERATING AUTHORITY.-

(A) APPLICATION REQUIRED.-Before commencing commercial air tour operations over a national park or tribal lands, a commercial air tour operator shall apply to the Administrator for authority to conduct the operations over the park or tribal lands.

(B) COMPETITIVE BIDDING FOR LIMITED CAPACITY PARKS.-Whenever an air tour management plan limits the number of commercial air tour operations over a national park during a specified time frame, the Administrator, in cooperation with the Director, shall issue operation specifications to commercial air tour operators that conduct such operations. The operation specifications shall include such terms and conditions as the Administrator and the Director find necessary for management of commercial air tour operations over the park. The Administrator, in cooperation with the Director, shall develop an open competitive process for evaluating proposals from persons interested in providing commercial air tour operations over the park. In making a selection from among various proposals submitted, the Administrator, in cooperation with the Director, shall consider relevant factors, including-

(i) the safety record of the person submitting the proposal or pilots employed by the person;

(ii) any quiet aircraft technology proposed to be used by the person submitting the proposal;

(iii) the experience of the person submitting the proposal with commercial air tour operations over other national parks or scenic areas;

(iv) the financial capability of the person submitting the proposal;

(v) any training programs for pilots provided by the person submitting the proposal; and

(vi) responsiveness of the person submitting the proposal to any relevant criteria developed by the National Park Service for the affected park.

(C) NUMBER OF OPERATIONS AUTHORIZED.-In determining the number of authorizations to issue to provide commercial air tour operations over a national park, the Administrator, in cooperation with the Director, shall take into consideration the provisions of the air tour management plan, the number of existing commercial air tour operators and current level of service and equipment provided by any such operators, and the financial viability of each commercial air tour operation.

(D) COOPERATION WITH NPS.-Before granting an application under this paragraph, the Administrator, in cooperation with the Director, shall develop an air tour management plan in accordance with subsection (b) and implement such plan.

(3) EXCEPTION.-Notwithstanding paragraph (1), commercial air tour operators may conduct commercial air tour operations over a national park under part 91 of title 14, Code of Federal Regulations if-

(A) such activity is permitted under part 119 of such title;

(B) the operator secures a letter of agreement from the Administrator and the national park superintendent for that national park describing the conditions under which the operations will be conducted; and

(C) the total number of operations under this exception is limited to not more than five flights in any 30-day period over a particular park.

(4) SPECIAL RULE FOR SAFETY REQUIREMENTS.-Notwithstanding subsection (c), an existing commercial air tour operator shall apply, not later than 90 days after the date of the enactment of this section, for operating authority under part 119, 121, or 135 of title 14, Code of Federal Regulations.
