# SUPPLEMENTARY INFORMATION:

This notice announces that the FAA finds that the noise exposure maps submitted by the City of Laredo, Texas for Laredo International Airport are in compliance with applicable requirements of Part 150, effective September 22, 2005. Under 49 U.S.C. 47503 of the Aviation Safety and Noise Abatement Act (hereinafter referred to as “the Act”), an airport operator may submit to the FAA noise exposure maps which meet applicable regulations and which depict non-compatible 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 Federal Aviation Regulations (FAR) part 150, promulgated pursuant to the Act, may submit a noise compatibility program for FAA approval which sets forth the measures the operator has taken or proposes to take to reduce existing non-compatible uses and prevent the introduction of additional non-compatible uses.

The FAA has completed its review of the noise exposure maps and accompanying documentation submitted by the City of Laredo. The documentation that constitutes the “noise exposure maps” as defined in section 150.7 of Part 150 includes the following from the August 2005, FAR Part 150 Noise Compatibility Study: Exhibit 4.5, Year 2005 Existing Condition Noise Exposure Map; Exhibit 5.2, Year 2010 Future Condition Noise Exposure Map; Appendix J maps consisting of Touch And Go/Overflight Flight Tracks Map, Departure Flight Tracks Map, and Arrival Flight Tracks Map; Table 4.4, 2005 Existing Condition Noise Exposure Estimates; Table 5.2, 2010 Future Condition-Case 1 Noise Exposure Estimates. There are no Historic Resources within the DNL 65 contour. The FAA has determined that these noise exposure maps and accompanying documentation are in compliance with applicable requirements. This determination is effective on September 22, 2005.

                    FAA's determination on 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 determination 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                           ( print page 57352)                        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 47503 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 47506 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 Part 150 or through FAA's review of 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 that submitted those maps, or with those public agencies and planning agencies with which consultation is required under section 47503 of the Act. The FAA has relied on the certification by the airport operator, under § 150.21 of FAR part 150, that the statutorily required consultation has been accomplished.                

                    Copies of the full noise exposure map documentation and of the FAA's evaluation of the maps are available for examination at the following locations: Federal Aviation Administration, 2601 Meacham Boulevard, Fort Worth, Texas; Laredo International Airport, 5210 Bob Bullock Loop, Laredo, Texas 78041. Questions may be directed to the individual named above under the heading                     **FOR FURTHER INFORMATION CONTACT**                    .                

Issued in Fort Worth, Texas, September 22, 2005.
