# AGENCY:

Federal Aviation Administration, DOT.

# ACTION:

Notice. 

# SUMMARY:

The Federal Aviation Administration (FAA) announces its determination that the noise exposure maps submitted by the Greater Orlando Aviation Authority for Orlando International Airport under the provisions of Title I of the Aviation Safety and Noise Abatement Act of 1979 (Pub. L. 96-193) 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 Orlando International Airport under part 150 in conjunction with the noise exposure maps, and that this program will be approved or disapproved on or before October 22, 2001.

# 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 23, 2001. The public comment period ends June 22, 2001.

# FOR FURTHER INFORMATION CONTACT:

Mr. John W. Reynolds, Jr., Federal Aviation Administration, Orlando Airports District Office, 5950 Hazeltine National Dr., Suite 400, Orlando, Florida 32822, (407) 812-6331, Extension 16. 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 Orlando International Airport are in compliance with applicable requirements of part 150, effective April 23, 2001. Further, FAA is reviewing a proposed noise compatibility program for that airport which will be approved or disapproved on or before October 22, 2001. This notice also announces the availability of this program for public review and comment.

Under section 103 of Title I of the Aviation Safety and Noise Abatement Act of 1979 (hereinafter referred 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 Federal Aviation Regulations (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 Greater Orlando Aviation Authority submitted to the FAA on April 3, 2001 noise exposure maps, descriptions and other documentation which were produced during the Orlando International Airport FAR part 150 Study, Noise Exposure Maps and Compatibility Plan conducted between July 7, 1997 and March 30, 2001. It was requested that the FAA review this material as the noise exposure maps, as described in section 103(a)(1) of the Act, and that the noise mitigation measures,                           ( print page 21811)                        to be implemented jointly by the airport and surrounding communities, be approved as a noise compatibility program under section 104(b) of the Act.                

The FAA has completed its review of the noise exposure maps and related descriptions submitted by the Greater Orlando Aviation Authority. The specific maps under consideration are “1999 DNL NOISE CONTOURS” and “2004 DNL NOISE CONTOURS” in the submission. The FAA has determined that these maps for Orlando International Airport are in compliance with applicable requirements. This determination is effective on April 23, 2001. 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 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 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 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 § 150.21 of FAR part 150, that the statutorily required consultation has been accomplished.

The FAA has formally received the noise compatibility program for Orlando International Airport, also effective on April 23, 2001. 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 22, 2001.

The FAA's detailed evaluation will be concluded under the provisions of 14 CFR part 150, § 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 noncompatible land uses and preventing the introduction of additional noncompatible 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 locations: Federal Aviation Administration, Orlando Airports District Office, 5950 Hazeltine National Dr., Suite 400, Orlando, Florida 32822.

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

Issued in Orlando, Florida, April 23, 2001.

John W. Reynolds, Jr.,

Assistant Manager, Orlando Airports District Office.
