# SUMMARY:

                        The Federal Aviation Administration (FAA) announces its determination that the Noise Exposure Maps submitted by the City of Atlanta for Hartsfield-Jackson Atlanta International Airport under the provisions of 49 U.S.C. 47501*et. seq.*                         (Aviation Safety and Noise Abatement Act) and 14 CFR part 150 are in compliance with applicable requirements. The FAA also announces that it is reviewing a proposed Noise Compatibility Program that was submitted for Hartsfield-Jackson Atlanta International Airport under Part 150 in conjunction with the Noise Exposure Map, and that this program will be approved or disapproved on or before October 7, 2007.                    

# DATES:

*Effective Date:*                         The effective date of the FAA's determination on the Noise Exposure Maps and of the start of its review of the associated Noise Compatibility program is April 10, 2007. The public comment period ends June 11, 2007.

Bonnie Baskin, Federal Aviation Administration, Atlanta Airports District Office, 1701 Columbia Avenue, Campus Building, Suite 2-260, College Park, Georgia 30337, 404-305-7152. Comments on the proposed Noise Compatibility Program should also be submitted to the above office.

# SUPPLEMENTARY INFORMATION:

This Notice announces that the FAA finds that the Noise Exposure Maps submitted for Hartsfield-Jackson Atlanta International Airport are in compliance with applicable requirements of Part 150, effective April 10, 2007. Further, FAA is reviewing a proposed Noise Compatibility Program for that Airport which will be approved or disapproved on or before October 7, 2007. This notice also announces the availability of this Program for public review and comment.

Under 49 U.S.C., Section 47503 of the Aviation Safety and Noise Abatement Act, (the Act), and 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 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 City of Atlanta submitted to the FAA on March 29, 2007 Noise Exposure Maps, descriptions and other documentation that were produced during the Hartsfield-Jackson Atlanta International Airport FAR Part 150 Study Noise Exposure Maps Report conducted between October 9, 2006 and April 6, 2007. It was requested that the FAA review this material as the Noise Exposure Maps, as described in Section 47503 of the Act, and that the noise mitigation measures, to be implemented jointly by the airport and surrounding communities, be approved as a Noise Compatibility Program under Section 47504 of the Act.

                    The FAA has completed its review of the Noise Exposure Maps and related descriptions submitted by the City of Atlanta. The specific documentation determined to constitute the Noise Exposure Maps includes: Map A—Noise Exposure Map: 2007;  Map B—Noise Exposure Map: 2012; Table 3.1, Average Daily Operations—2007; Table 3.2, Aircraft Fleet Mix—2007; Table 3.3, Percent Runway Utilization by Time of Day7—2007; Table 3.4, Departure Headings—2007; Figure 3-2, NOMS Data—East Flow Tracks; Figure 3-3, NOMS Data—West Flow Tracks; Figure 3-4, 2007 East Flow Corridors; Figure 3-5, 2007 West Flow Corridors; Table 3.5, Departure Stage Length: Air Carrier Aircraft—2007; Table 3.6, Nighttime Operations—2007; Table 3.8, Noise                           ( print page 20160)                        Contours: Estimated Population—2007; Table 3.10, Noise Levels at Noise Sensitive Sites (other than residential)—2007; Table 4.1, Average Daily Operations—Future 2012; Table 4.2, Aircraft Fleet Mix—2012; Table 4.3, Percent Runway Utilization by Time of Day—2012; Table  4.5, Noise Exposure Contours: Population—2012; and Appendix D, Runway Utilizations. The FAA has determined that these maps for Hartsfield-Jackson Atlanta International Airport are in compliance with applicable requirements. This determination is effective on April 10, 2007. FAA's determination on the 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 airport operator'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 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 exposure 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 Section 150.21 of part 150, that the statutorily required consultation has been accomplished.

The FAA has formally received the Noise Compatibility Program for Hartsfield-Jackson Atlanta International Airport, also effective on April 10, 2007. Preliminary review of the submitted material indicates that it conforms to the requirements for the submittal of Noise Compatibility Programs, but that further review will be necessary prior to approval or disapproval of the program. The formal review period, limited by law to a maximum of 180 days, will be completed on or before October 7, 2007.

The FAA's detailed evaluation will be conducted under the provisions of Part 150, Section 150.33. The primary considerations in the valuation process are whether the proposed measures may reduce the level of aviation safety, create an undue burden on interstate or foreign commerce, or be reasonably consistent with obtaining the goal of reducing existing non-compatible land uses and preventing the introduction of additional non-compatible land uses.

Interested persons are invited to comment on the proposed program with specific reference to these factors. All comments, other than those properly addressed to local land use authorities, will be considered by the FAA to the extent practicable. Copies of the Noise Exposure Maps, the FAA's evaluation of the maps, and the proposed Noise Compatibility Program are available for examination at the following location: Federal Aviation Administration, Atlanta Airports District Office, 1701 Columbia Avenue, Campus Building, Suite 2-260, College Park, Georgia 30337.

                    Questions may be directed to the individual named above under the heading,                     **FOR FURTHER INFORMATION CONTACT**                    .                 

Issued in Atlanta, Georgia April 10, 2007.
