In the examples in both Tables 1 and 2, the greatest reductions in either noise or the population exposed to noise are at the DNL 45–60 dB level, which is the lowest noise level that the FAA normally evaluates for differences in noise that may result from certain proposed changes in procedures. In Table 1, there are increases in the number of people in higher noise exposure bands of DNL 60–65 dB and above DNL 65 dB. In Table 2, the average DNL decrease occurs in the lowest noise exposure band, while the average DNL change in the higher noise exposure bands is either zero or a slight increase using the population weighted average approach.

The use of the total of all three DNL noise exposure bands to determine a net noise reduction gives equal weight to lower and higher levels of noise, while the FAA’s practice is to give greater weight to higher noise levels which people find more annoying, especially noise levels above DNL 65 dB. Accordingly, the FAA is considering the extent to which a mix of noise increases and decreases in different noise exposure bands supports a determination of noise reduction, especially when reductions at lower DNL noise levels would outweigh increases at higher noise levels. A potential alternative approach could be to require reductions in all three DNL noise exposure bands to support a noise reduction determination for use of the CATEX. This alternative approach would be expected to reduce the use of the CATEX, and it appears less consistent with the statutory provision to compare procedures ‘‘in the same airspace.’’ The FAA invites comments on this aspect of the Net Noise Reduction Method.

Finally, if the FAA decides to use the Net Noise Reduction Method or a variation of it, the FAA must also decide if and how to employ its significant noise impact threshold. The decision that is the most consistent with the statutory language would be not to employ the threshold at all. The statutory text is prescriptive in that a PBN procedure that meets the test for measurable reductions ‘‘shall be presumed to have no significant affect [sic] on the quality of the human environment and the Administrator shall issue and file a categorical exclusion for the new procedure.’’ Unlike CATEXes that are administratively established under CEQ regulations, this legislative CATEX is not subject to extraordinary circumstances; therefore, a CATEX determination is not precluded by potential environmental impacts that are beyond the specific parameters in the statutory text (i.e, measureable reductions in fuel consumption, carbon dioxide emissions, and noise on a per flight basis). As the FAA considers the viability of employing the significant noise impact threshold in conjunction with this CATEX, the FAA is soliciting public views on whether a threshold test may and should be used. Further, if a significant noise impact threshold test is used, should it be used only when there is a net increase in people exposed at DNL 65 dB and above, as the NAC Task Group has suggested, or should it be more broadly used to check for significant noise impact when there is any increase in the number of people exposed to noise at DNL 65 dB and above—even if there is a net population benefit at that level?
Solicitation of Public Comment

The FAA invites public comment on the entirety of the prospective implementation of the CATEX in Section 213(c)(2) of the FAA Modernization and Reform Act of 2012, and particularly invites comment on the following specific aspects of the Net Noise Reduction Method which are under consideration by the FAA as described in this notice:

1. Extent to which the FAA should rely on the Net Noise Reduction Method to determine measurable reductions in noise on a per flight basis.

2. Appropriateness of determining that there is a measurable reduction in noise if people receiving a noise decrease outnumber the people receiving an increase, but the noise decrease is small compared to the noise increase.

3. Different approaches to a net noise reduction methodology (i.e., population change, noise change, population weighted noise change), and whether the selection of one approach over another is preferred and increases public understanding. 4. Extent to which a mix of noise increases and decreases could support a determination of measurable noise reduction, especially when reductions at lower noise levels outweigh increases at higher noise levels, and whether an alternative approach that would require reductions in all three noise exposure bands to support the use of the CATEX should be used.

5. Whether a significant noise impact threshold test should be used; and if so, if it should be used only when there is a net increase in people exposed to noise at DNL 65 dB and above, or if it should be used when there is any increase in the number of people exposed to noise at DNL 65 dB and above—even if there is a net population benefit at that level.
