SUPPLEMENTARY INFORMATION:

This notice announces that the FAA finds that the Noise Exposure Maps submitted for Louisville International Airport are in compliance with applicable requirements of Title 14 Code of Federal Regulations (CFR) part 150, effective April 7, 2011. Under 49 U.S.C. section 47503 of the Aviation Safety and Noise Abatement Act (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 14 CFR part 150, promulgated pursuant to the Act, may submit a Noise Compatibility Program for FAA approval which sets forth the measures the airport operator has taken or proposes to take to reduce existing noncompatible uses and prevent the introduction of additional noncompatible uses.

The FAA has completed its review of the Noise Exposure Maps and accompanying documentation submitted by Louisville Regional Airport Authority. The documentation that constitutes the “Noise Exposure Maps” as defined in Section 150.7 of 14 CFR part 150 includes: Figure 11, “Existing Condition 2011 Noise Exposure Map”; Figure 12, “Forecast Condition 2012 Noise Exposure Map”; Figure 4, “Existing 2011 North Flow Arrival and Departure Tracks”; Figure 5, “Existing 2011 South Flow Arrival and Departure Tracks”; Figure 6, “Forecast 2016 North Flow Arrival and Departure RNAV Tracks”; Figure 7, “Forecast 2016 South Flow Arrival and Departure RNAV Tracks”; Figure 8, “Military Arrival and Departure Tracks”; Figure 13, “Comparison of Existing 2011 and Forecast 2016 Noise Exposure Maps”; Table 4, “2011 Operations Summary”; Table 5, “Modeled Average Daily Aircraft Operations for 2011”; Table 6, “2016 Operations Summary”; Table 7, “Modeled Average Daily Aircraft Operations for 2016”; Table 9, “Overall Runway Use Percentages for 2011”; Table 10, “Modeled Average Daily Runway Use for 2011”; Table 14, “Overall Runway Use Percentages for 2016”; Table 15, “Modeled Average Daily Runway Use for 2016”; Table 21, “Military Helicopter Flight Tracks and Use”; Table 25, “Estimated Residential Population within 2011 and 2016 DNL Contours”. The FAA has determined that these Noise Exposure Maps and accompanying documentation are in compliance with applicable requirements. This determination is effective on April 7, 2011.

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 Start Printed Page 21420procedures contained in Appendix A of 14 CFR 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 14 CFR 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 14 CFR part 150, that the statutorily required consultation has been accomplished.

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