The FAA also announces that it is reviewing a proposed noise compatibility program that was submitted for Missoula International Airport under part 150 in conjunction with the noise exposure map, and that this program will be approved or disapproved on or before July 2, 2005.

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 January 3, 2005. The public comment period ends March 4, 2005.

FOR FURTHER INFORMATION CONTACT:

Dennis Ossenkop, Federal Aviation Administration, Airports Division, 1601 Lind Ave. SW., Renton, WA, 98055-4056, telephone [phone]. 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 Missoula International Airport are in compliance with applicable requirements of part 150, effective January 3, 2005. Further, the FAA is reviewing a proposed noise compatibility program for that airport which will be approved or disapproved on or before July 2, 2005. This notice also announces the availability of this program for public review and comment.

Under 49 U.S.C., 47503 (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 the 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 noncompatible uses.

The Acting Director of the Missoula International Airport submitted to the FAA on January 4, 2005, noise exposure maps, descriptions and other documentation that were January 4, 2005, noise exposure maps, descriptions and other documentation that were produced during the Missoula International Airport FAR part 150 Study dated May 2004 and a Supplemental Report dated June 2004. 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 director of the Missoula International Airport. The specific documentation determined to constitute the noise exposure maps includes the following from the Missoula International Airport FAR Part 150 Study of May 2004 and Supplemental Report of June 2004:

• Figure S1 at page S.4, Existing Noise Exposure Map, 2003;
• Figure S2 at page S.7, Future Noise Exposure Map, 2009;
• Figures C9 and C10 noise monitoring locations;
• Figure C11 at page C.35 Departure Flight Tracks;
• Figure C12 at page C.36 Arrival Flight Tracks;
• Table S1 at page S.2 Revised Summary of Aviation Forecasts 2003-2023 and additional aviation activity data;
• Table S3 at page S.5 Existing Land Use Within Existing Noise Contours 2003 presents estimates of the number of persons residing with the DNL 55, 60, and 65 noise contours;
• Table S4 at page S.6 Future Noise Exposure Map with Existing Land Use, 2009, presents estimates of the number of persons residing with the DNL 55, 60, and 65 noise contours;
• Appendix H in the Revised Report volume and starting at page S.32 in the Supplemental Report Consultation actions.
• There are no properties on or eligible for inclusion in the National Register of Historic Places with the DNL 65 noise contour.

The FAA has determined that these maps for Missoula International Airport are in compliance with applicable requirements. This determination is effective on January 3, 2005. The 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 constitute 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 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 the 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 FAR part 150, that the statutorily required consultation has been accomplished.

The FAA has formally received the noise compatibility program for Missoula International Airport, also effective on January 2, 2005. 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 July 2, 2005.

The FAA's detailed evaluation will be conducted under the provisions of 14 CFR part 150, section 150.33. The primary considerations in the evaluation 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. The FAA will consider all comments, other than those properly addressed to local land use authorities, 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 locations: Federal Aviation Administration, Airports Division, 1601 Lind Avenue, SW., Suite 315, Renton, Washington. Helena Airports District Office, FAA Building, Suite 2, Helena, Montana. Missoula International Airport, 5225 Highway 10 West, Missoula, Montana.

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

Issued in Renton, Washington, January 3, 2005.
