Noise Mitigation Report APPENDIX Q COMMENTS AND RESPONSES ON THE NOISE MITIGATION REPORT Introduction The New York/New Jersey/Philadelphia (NY/NJ/PHL) Metropolitan Area Airspace Redesign Project (Redesign Project) presented the Draft Environmental Impact Statement (DEIS) for public review and comment in the winter of 2006. The comments that were received on the DEIS were used to inform the selection of the Preferred Alternative. Many of these comments proposed noise mitigation strategies, which were evaluated for operational feasibility and potential for reduction of noise exposure. A Mitigated Preferred Alternative was presented to the public in April 2007, along with the results of the operational and noise analyses, for additional review and comment. This document contains the responses to the public comments on the Preferred Alternative and its mitigation. 40 CFR Section 1503.4 (Response to comments) requires that an agency preparing a Final EIS assess and consider comments both individually and collectively, and respond accordingly. The Federal Aviation Administration (FAA) has the option to provide separate responses to individual comments identified in commenter’s letters or, where the volume of letters is so large or the nature of comments are similar, responses may be provided in a topical format. This appendix to the Final EIS provides responses in topical format. Comment letters and petitions received on the Preferred Alternative and mitigation strategies totaled over 1,700. Each of the comment letters and petitions were reviewed, and many similar themes and issues were identified, resulting in 297 unique topical comments. To assist the reader in identifying specific letters or topics, the following are included: • A table of issues raised in the comment letters which directs the reviewer to the appropriate topic and subtopic for a response; • Topical responses to issues raised; • An index listing all the letters received sorted by the author; and • Copies of letters received from elected officials, federal and state agencies, and special interest groups (in numerical order by control number). The topical responses are ordered in 24 groupings. Those related to the Preferred Alternative and mitigation, applicable to the entire study area, appear first. General topic comments on process, modeling, quality of life and other issues are next. Airport-specific comments are found towards the end of the document. A section number has been assigned to each grouping. A representative comment for each topic and subtopic is displayed in italics, while the response appears directly below this statement. Further references to sections in the main body of the Final EIS are located within each response when appropriate.

  • Case Study on Aircraft Noise Reduction by Variation of Departure Profiles During Night Flights
    Deutscher Luft- und Raumfahrtkongress 2019 DocumentID: 490198 CASE STUDY ON AIRCRAFT NOISE REDUCTION BY VARIATION OF DEPARTURE PROFILES DURING NIGHT FLIGHTS M. Mitzkat, C. Strümpfel - Technische Universität Berlin Institute of Aeronautics and Astronautics, Chair of Flight Guidance and Air Transport Marchstr. 12, 10587 Berlin, Germany [email protected] [email protected] Abstract Since the civil air transportation sector has been growing significantly, with an increase not only in number of flights, but also with regards to their environmental impact, emissions have been growing to the same degree. Residents in areas around airports are therefore exposed to an increasing strain of noise pollution. Past scientific research has identified large potential through the implementation of operational noise abatement procedures. The following paper will present a case study concerning noise abatement procedures during departure flight phase as a measure to reduce aircraft noise. The study was conducted on behalf of the aircraft noise commission council of Berlin-Tegel airport. The main objective of this research was to assess whether the reduction of aircraft noise pollution can be achieved by noise abatement procedures, which are specifically adapted for the purpose of night-flights. Therefore, regular domestic overnight airmail flights were conducted as test flights between Berlin-Tegel airport and Stuttgart-Echterdingen airport. Those flights, which were performed from August 2016 to May 2017, qualify perfectly for this study, due to their specific schedule and uniform testing environment combined with a higher general focus on night-time noise immissions. In order to develop sustainable operational procedures for aircraft noise reduction, a holistic approach is nec- essary.

    1 U.S. DEPARTMENT OF TRANSPORTATION FEDERAL AVIATION ADMINISTRATION EASTERN SERVICE AREA CATEGORICAL EXCLUSION DECLARATION/RECORD OF DECISION The Federal Aviation Administration (FAA) has determined that the following proposed airspace procedure changes associated with Ronald Reagan Washington National Airport (DCA) are categorically excluded from further environmental review under the National Environmental Policy Act (NEPA). To enhance national security, and in response to a request from the United States Secret Service (USSS), the proposed action amends eight existing north flow standard instrument departures (SIDs) by moving one waypoint approximately 784 feet to the southwest to direct aircraft further away from protected airspace above the White House and Naval Observatory. Additionally, in response to a request from the Reagan National Community Noise Working Group, the proposed action amends one waypoint on six existing SIDs, which will route aircraft closer to the Potomac River. Furthermore, the proposed action will establish the AMEEE1 SID to replace the HOLTB1 and BOOCK3, both of which will be canceled. The AMEEE procedure will use the new waypoint established for national security, and will otherwise not change from the procedures it is replacing. Finally, to integrate air traffic with the Northeast Corridor (NEC) and Atlantic Coast Routes (ACR) procedures, the action proposes to implement the SCOOB transition by extending the AMEEE (HOLTB/BOOCK replacement procedure) enroute transition beyond waypoint COLIN to SCOOB. This final action also requires amending the Baltimore Washington Airport (BWI) CONLE SID and Dulles Airport (IAD) JCOBY SID to establish the SCOOB Transition beyond COLIN waypoint. The SCOOB transition will be used for aircraft flying over 18,000 feet above ground level (AGL).

The USA, however, home of both the entire hushkit industry and the vast majority of the operators and owners of the potentially affected aircraft, immediately demanded the regulation’s repeal, denouncing its purely protectionist intent and effects and threatening the EU with retaliatory action. After a lengthy political and legal controversy the EU, in Octo- ber 2001, gave in and withdrew the legislation. In this paper we evaluate the late ’hush- kit regulation‘ from three different perspectives – environmental policy, trade policy and rent-seeking potential – to determine its respective merits and demerits.

CURRENT STATE OF THE LAW IN AIRCRAFT NOISE POLLUTION CONTROL MAnUN K. NORTH INTRODUCTION Noise, defined as "unwanted sound,"' has become a global prob- lem.' It is said that the United States is the noisiest country on the planet, with noise pollution reaching crisis proportions.3 There are countless sources of noise; construction equipment, industrial machinery, automobiles, and aircraft are some of the more glaring examples. There are many adverse effects, both physiological and behavioral, from noise; hearing loss or impairment, interference with sleep, fatigue, pain in the auditory systems, loss of equi- librium, stress and debilitating effect on human organs, speech interference, dream interruption, hindrance of concentrated mental effort, interference with task performance, annoyance and irrit- ability, interference with relaxation and recreation, and feelings of loss of privacy." Attention has been focused on aircraft noise abatement due to the severity of the problem In the United States approximately six million people live where the levels of aircraft noise create a signifi- cant annoyance." Further, approximately 600,000 of these citizens live in areas severely impacted by aircraft noise.' Other aspects of aircraft noise pollution which makes a solution desirable are its monetary cost to airport proprietors and the safety hazards caused by airport noise-abatement procedures.

    ISSN: 2634 - 8845 Journal of Earth and Environmental Sciences Research Research Article Open Access An Assessment of the Impact of Helicopter Noise: Case Study of Mgbuoshimini Community Nigeria OF Orikpete1*, TG Leton1, VE Amah1 and DRE Ewim2 1Centre for Occupational Health, Safety and Environment, Institute of Petroleum Studies, University of Port Harcourt PMB 5323 Choba, Rivers State, Nigeria 2Nigeria Atomic Energy Commission, Abuja, Nigeria ABSTRACT With the projected growth in demand for commercial aviation, it is anticipated that there will be an increased environmental impact associated with noise, air quality, and climate change. Against this backdrop, the noise levels experienced by the residents of Mgbuoshimini Community due to helicopters take- off and landing were studied. The study was carried out for 14 days at three different locations using a Class 2 Optimus sound level meter from 7am to 5pm daily. Analysis involved the equivalent noise levels, statistical measures for the background noise, aircraft flyover noise as well as the Noise Gap Index (NGI) . It was found that the equivalent noise levels of the background noise and aircraft flyover noise range from 67.7 dBA to 72.4 dBA and 88.4 dBA to 88.6 dBA respectively. The peak background noise and aircraft flyover noise ranged from 69.17 dBA to 79 dBA and 93.2 dBA to 94.8 dBA respectively. These values exceeded the recommended value of 60 dBA for residential areas. Two models to determine the NGI for both low noise areas and high noise areas were developed. A correlation coefficient of 0.70 and 0.88 were obtained between the actual and predicted values of NGI for both low and high noise areas.

  • Aircraft Noise Pollution, Soundproofing, and Lagging House
    Aircraft Noise Pollution, Soundproofing, and Lagging House Price Adjustments: Evidence from the Minneapolis-St. Paul International Airport∗ Felix L. Friedty Jeffrey P. Cohenz Macalester College University of Connecticut Abstract Soundproofing of homes is one approach to mitigating the impacts of airport noise. A lack of available information on soundproofing, however, has limited the ability of researchers to utilize this as an identification strategy for estimating the causal impacts of noise on house prices. In this paper, we focus on Minneapolis-St. Paul International Airport (MSP), and examine the airport noise impacts on housing prices by using two soundproofing initiatives for MSP as an identification strategy. We use information on properties that were eligible for soundproofing, after the soundproofing initiatives, to identify the causal impact of noise on house prices. We find that the magnitudes of the noise impacts on housing prices are approximately 2% per decibel, and are statistically significant. These findings hold up to a broad range of specifications and robustness checks. Our findings are the first known results that depend on using soundproofing eligibility to identify the causal impacts of noise on house prices. We also calculate an estimated return on investment (ROI) for residential soundproofing, and find that this ROI could reach as high as 40% in the areas around MSP.

  • Traffic Noise and Housing Values: Evidence from an Airport Concession Renewal
    Traffic Noise and Housing Values: Evidence from an Airport Concession Renewal Samuel Lindgren – VTI CTS Working Paper 2018:15 Abstract Credible estimates of the cost of traffic noise are crucial to the assessment of the merits of noise control policies. This study estimates the cost of aircraft noise by measuring its capitalization into housing prices following an unexpected renewal of the operating contract for a local airport. The results show that a one decibel increase in aircraft noise leads to a reduction in housing values of 0.3 percent, or $1,200, on average. The capitalization rate is larger the higher is the property’s value, size and standard which suggest that owners of these houses benefit relatively more from noise abatement measures.

  • Aircraft Noise and Public Health: Acoustical Measurement and Social Survey Around Sydney (Kingsford Smith) Airport
    AIRCRAFT NOISE AND PUBLIC HEALTH: ACOUSTICAL MEASUREMENT AND SOCIAL SURVEY AROUND SYDNEY (KINGSFORD SMITH) AIRPORT By Tharit Issarayangyun Bachelor of Civil Engineering (second honour), Master of Civil Engineering A thesis submitted in fulfillment of the requirement for the degree of DOCTOR OF PHILOSOPHY SCHOOL OF CIVIL AND ENVIRONMENTAL ENGINEERING THE UNIVERSITY OF NEW SOUTH WALES SYDNEY, AUSTRALIA March, 2005 PLEASE TYPE THE UNIVERSITY OF NEW SOUTH WALES Thesis/Project Report Sheet Surname or Family name: ISSARAYANGYUN First name: THARIT Other name/s: Abbreviation for degree as given in the University calendar: PhD School: Civil & Environmental Engineering Faculty: Engineering Title: Aircraft Noise and Public Health: Acoustical Measurement and Social Survey around Sydney (Kingsford Smith) Airport Abstract 350 words maximum: (PLEASE TYPE) The development of major commercial airports promotes the air transport industry and generates positive economic benefits to the airport and to its host economy. However, external costs are associated with these benefits. Any increase in aircraft movement causes negative environmental impacts, especially noise pollution. Governments have reduced aircraft noise levels at their sources, or introduced aircraft noise management strategies; however the problems have never been satisfactorily resolved. This research aims at developing a better understanding of the impacts of aircraft noise on community health and well-being by exploring two core research questions: (1) “Is health related quality of life worse in communities chronically exposed to aircraft noise than in communities not exposed?”; and (2) “Does long-term aircraft noise exposure associate with adult high blood pressure level via noise stress as a mediating factor?”. The Sydney (Kingsford Smith) Airport has been selected as a case study.
