Part 150 Noise Compatibility Program

UpdateShreveport Regional Airport

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

BACKGROUND AND PROCESSPart 150 Noise Compatibility Program Update

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

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

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

Study Process – Where We Are

NOISE ANALYSIS METHODOLOGY

Part 150 Noise Compatibility Program Update

Integrated Noise Model

• Computer model developed by the FAA• Federal regulations (14 CFR Part 150) require

the use of the INM in preparing Noise Exposure Maps

INM Input Data

• The number of takeoffs and landings by time of day, aircraft type, and stage length (distance to destination)

• Runway use• Location and use of flight tracks • Average annual temperature and humidity• Airport elevation• Runway end coordinates• Terrain

Existing and Forecast Operations (Takeoffs and Landings)

UPDATED NOISE EXPOSUREPart 150 Noise Compatibility Program Update

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.

NOISE LAND INVENTORY AND REUSE PLAN


FAA Requirements

• Airport operators must maintain an inventory of land purchased with Airport Improvement Program noise funding

• Airport operators much prepare plans for the reuse of noise lands that are not necessary to retain in airport ownership

• Noise lands released for reuse must be developed for noise-compatible uses
