(1)In general Notwithstanding any other provision of law, for purposes of section 3(b)(1) of Public Law 100-91 (16 U.S.C. 1a-1 note), the substantial restoration of the natural quiet and experience of the Grand Canyon National Park (in this section referred to as the “Park”) shall be considered to be achieved in the Park if, for at least 75 percent of each day, 50 percent of the Park is free of sound produced by commercial air tour operations that have an allocation to conduct commercial air tours in the Park as of the date of enactment of this Act. ####
(2)Considerations #####
(A)In general For purposes of determining whether substantial restoration of the natural quiet and experience of the Park has been achieved in accordance with paragraph (1), the Secretary of the Interior (in this section referred to as the “Secretary”) shall use— ######
(i)the 2-zone system for the Park in effect on the date of enactment of this Act to assess impacts relating to substantial restoration of natural quiet at the Park, including— ######
(I)the thresholds for noticeability and audibility; and ######
(II)the distribution of land between the 2 zones; and ######
(ii)noise modeling science that is— ######
(I)developed for use at the Park, specifically Integrated Noise Model Version 6.2; ######
(II)validated by reasonable standards for conducting field observations of model results; and ######
(III)accepted and validated by the Federal Interagency Committee on Aviation Noise. #####
(B)Sound from other sources The Secretary shall not consider sound produced by sources other than commercial air tour operations, including sound emitted by other types of aircraft operations or other noise sources, for purposes of— ######
(i)making recommendations, developing a final plan, or issuing regulations relating to commercial air tour operations in the Park; or ######
(ii)determining under paragraph
(1)whether substantial restoration of the natural quiet and experience of the Park has been achieved. ####
(3)Continued monitoring The Secretary shall continue monitoring noise from aircraft operating over the Park below 17,999 feet MSL to ensure continued compliance with the substantial restoration of natural quiet and experience of the Park. ####
(4)Day defined For purposes of this section, the term “day” means the hours between 7:00 a.m. and 7:00 p.m. ###
(b)Conversion to Quiet Technology Aircraft ####
(1)In general Not later than 15 years after the date of enactment of this Act, all commercial air tour aircraft operating in the Grand Canyon National Park Special Flight Rules Area shall be required to fully convert to quiet aircraft technology (as determined in accordance with regulations in effect on the day before the date of enactment of this Act). ####
(2)Conversion incentives Not later than 60 days after the date of enactment of this Act, the Secretary and the Administrator of the Federal Aviation Administration shall provide incentives for commercial air tour operators that convert to quiet aircraft technology (as determined in accordance with the regulations in effect on the day before the date of enactment of this Act) before the date specified in paragraph (1), such as increasing the flight allocations for such operators on a net basis consistent with section 804(c) of the National Park Air Tours Management Act of 2000 (title VIII of Public Law 106-181), provided that the cumulative impact of such operations does not increase noise at Grand Canyon National Park.
