# SUPPLEMENTARY INFORMATION:

                    This notice announces that the FAA finds that the Noise Exposure Maps submitted for Williams Gateway Airport, Mesa, Arizona are in compliance with applicable requirements of Federal                           ( print page 31052)                        Aviation Regulations (FAR) Part 150, effective May 2, 2000.                

Under Section 103 of the Aviation Safety and Noise Abatement Act of 1979 (hereinafter referred to as “the Act”), an airport operator may submit to the FAA Noise Exposure Maps which meet applicable regulations and which depict noncompatible land uses as of the date of submission of such maps, a description of projected aircraft operations, and the ways in which such operations will affect such maps. The Act requires such maps to be developed in consultation with interested and affected parties in the local community, government agencies, and persons using the airport.

An airport operator who has submitted Noise Exposure Maps that are found by FAA to be in compliance with the requirements of FAR Part 150, promulgated pursuant to Title I of the Act, may submit a Noise Compatibility Program for FAA approval which sets forth the measures the operator has taken or proposes for the reduction of existing noncompatible uses and for the prevention of the introduction of additional noncompatible uses.

The FAA has completed its review of the Noise Exposure Maps and supporting documentation submitted by the Williams Gateway Airport Authority. The specific maps under consideration are Exhibit 1, “1999 Noise Exposure Map” and Exhibit 2, “2004 Noise Exposure Map” in the submission. The FAA has determined that these maps for Williams Gateway Airport are in compliance with applicable requirements. This determination is effective on May 2, 2000. FAA's acceptance of an airport operator's Noise Exposure Maps is limited to a finding that the maps were developed in accordance with the procedures contained in Appendix (A) of FAR Part 150. Such acceptance does not constitute approval of the applicant's data, information or plans, or a commitment to approve a Noise Compatibility Program or to fund the implementation of that program.

If questions arise concerning the precise relationship of specific properties to noise exposure contours depicted on a Noise Exposure Map, submitted under Section 103 of the Act, it should be noted that the FAA is not involved in any way in determining the relative locations of specific properties with regard to the depicted noise contours, or in interpreting the Noise Exposure Maps to resolve questions concerning, for example, which properties should be covered by the provisions of Section 107 of the Act. These functions are inseparable from the ultimate land use control and planning responsibilities of local government. These local responsibilities are not changed in any way under FAR part 150 or through FAA's review of the Noise Exposure Maps. Therefore, the responsibility for the detailed overlaying of noise exposure contours onto the map depicting properties on the surface rests exclusively with the airport operator which submitted those maps, or with those public agencies and planning agencies with which consultation is required under Section 103 of the Act. The FAA has relied on the certification by the airport operator, under Section 150.21 of Part 150, that the statutorily required consultation has been accomplished.

Copies of the Noise Exposure Maps and of the FAA's evaluation of the maps are available for examination at the following locations:

Issued in Hawthorne, California on May 2, 2000.
