2. Agenda - April 13, 2015 Part 150 Study Background and Process Noise Analysis Methodology Updated Noise Exposure Noise Measurement Program Noise Land Inventory and Reuse Plan Next Steps

3. BACKGROUND AND PROCESS Part 150 Noise Compatibility Program Update

4. What is a Part 150 Study? Voluntary federal program for airports seeking to understand and reduce effects of noise exposure Study requirements are set forth in 14 CFR Part 150, Airport Noise Compatibility Planning A complete Part 150 Study includes: – Noise Exposure Maps (NEM) Current and forecast aircraft noise – Noise Compatibility Program (NCP) Noise abatement measures Noise mitigation measures Land use management measures Implementation and monitoring measures

5. Noise Compatibility Studies at Shreveport 1984 Airport Noise and Land Use Compatibility (ANCLUC) Study – FAA approval not required 1991 Part 150 NEM/NCP – Approved by FAA in 1992 2004 Part 150 NEM/NCP – Approved by FAA in 2007

6. Purpose of 2014 Part 150 Update To determine how recent changes in air service have affected noise exposure To revise NCP based on changes in noise exposure Why? – In 2012, FAA directed Airport Authority to suspend noise mitigation projects of the 2004 NCP FAA wanted Airport Authority to update NEMs given changes in air service since 2004

23. UPDATED NOISE EXPOSURE Part 150 Noise Compatibility Program Update

24. The DNL Noise Metric - Example NOTES: DNL is the metric (or descriptor) that the FAA and the U.S. Department of Defense use to describe the noise environment around civilian and military airports. DNL is the total, time-weighted noise occurring during a 24-hour period. Events after 10:00 p.m. and before 7:00 a.m. are assigned an extra 10 decibels (dB) in the DNL calculation to reflect the increased sensitivity of people to nighttime noise. For Part 150 studies, the DNL levels are calculated for an “average day” during the study year. In this example, 34 aircraft noise events occur during the 24-hour period – 25 in daytime and 9 in nighttime hours. The noise levels range from 78 dB to 103 dB. The extra 10 dB assigned to the nighttime events gives them noise levels as high as 112 dB. The cumulative aircraft noise level for the 24-hour period is DNL 67.
