Stirring from their usual slumber, in the face of increasing community dissatisfaction with respect to noise and emissions from aircraft overflight, the Federal Aviation Administration (“FAA”) and United States Congress each took some action in recent months. First, FAA awarded more than $19 million to various universities and other organizations through the “ASCENT” program, a cooperative aviation research organization founded in 2014 (but apparently only lightly funded until now).

The primary purpose of the grants was to allow the universities to study ways to reduce aviation noise. Many of those awards were for noise resulting from episodic impacts of: (1) uncrewed aircraft; (2) supersonic aircraft; and (3) advanced air mobility or AIM. However, giving some thought to more “mundane” causes, FAA gave nearly $2 million to Boston University to study the relationship between aircraft noise, sleep, mental health, and cardiovascular health. Similarly, the University of Pennsylvania received slightly over $1 million to study the way in which noise from aircraft affects sleep. All of these latter grants go to the fundament of impacted communities’ concerns.Continue Reading FAA and Congress Finally Awaken to Citizens’ Discontent with Aircraft Noise Impacts

It is likely that the public may be somewhat disappointed with Congress’ latest effort to ameliorate the impacts of airport noise on underlying populations. On November 18, 2021, Adam Smith, Member of the House of Representatives from Washington State, introduced the Aviation Noise and Emissions Act, H.R. 6050, a Bill intended to “develop pilot grant programs through the Environmental Protection Agency to research and collect data on aircraft and airport noise and emissions and to use such information and data to develop a mitigation strategy, and for other purposes.” H.R. 6050, p. 1. At its foundation, the Bill calls for a “3-year pilot grant program with eligible entities to measure noise and emissions, including greenhouse gases, particulate matter, ultrafine particles, and other toxic pollutants, in communities near airports or air flight pathways using sophisticated methods and technology that allow tracing of noise and emissions to specific sources . . .,” H.R. 6050, paragraph 2.a., including identifying the primary recipients of such noise such as specific neighborhoods, structures, or impacted areas.

Communities challenging, or considering a challenge, to the noise and other impacts from low-flying aircraft, enabled in new flight paths and altitudes by the Federal Aviation Administration’s (“FAA”) NextGen Initiative, may find some comfort in the knowledge that they are not alone. Communities from coast to coast, even including communities that are themselves airport proprietors, have recently joined the group of communities that earlier brought legal action against FAA to vindicate their citizens’ interests, some of which suits are only now approaching decision.

First chronologically, the City of Los Angeles, owner and operator of Los Angeles International Airport (“LAX”), brought suit in December 2019, in the United States Court of Appeals for the Ninth Circuit, challenging a southerly shift in flight tracks of departing aircraft from Bob Hope (Hollywood-Burbank) Airport, City of Los Angeles v. FAA, Case No.19-73164, alleging FAA either failed to review the revised flight paths under NEPA, or failed to take action required by law to ensure reasonable compliance with assigned flight tracks. In its opposition, FAA first argued that it is not responsible for the divergence from established flight tracks, but, rather, it is due to “Acts of God,” such as wind, weather, and flocks of birds. It was only months later, when FAA realized that excuse wouldn’t “fly,” that it assumed responsibility by claiming the need to “vector” aircraft off established flight tracks for safety purposes. After Court-supervised mediation efforts were unsuccessful, briefing was completed in September 2020, but no decision has been made by the Court to date. That case is not by any means the end of the story.Continue Reading Communities Challenging NextGen Are In Good Company

On January 13, 2021, the Federal Aviation Administration (“FAA”) published, in the Federal Register, Vol. 86, No. 8, Docket No. FAA-2021-0037, p. 2722, a necessary, if somewhat belated, “summary to the public of the research programs it sponsors . . . that could potentially inform future aircraft noise policy.” While the “spirit” appears willing, the “execution” is weak.

FAA first claims, by way of “background,” that “the number of people living in areas exposed to SIGNIFICANT levels of aircraft noise in the United States has declined from roughly 7 million to just over 400,000 today.” Id., at 2723 [emphasis added]. FAA credits that reduction principally to “phased transition to quieter aircraft;” efforts by local governments to reduce the number of people living in close proximity to airports through planning; sound insulation; and, perhaps most ironically, the introduction of Performance Based Navigation (“PBN”), or RNAV procedures which consolidate flight corridors, thus reducing the NUMBER of persons overflown, while, at the same time, increasing noise for residents under the newly consolidated flight tracks.

FAA’s conclusions are skewed by reliance on outdated assumptions.Continue Reading FAA Research on Environmental Issues Ignores Significant Factors in Public Discontent

In a June 19, 2020 Findings of Fact, Conclusions of Law, and Judgment (“Judgment”), the District Court of Jefferson County, Colorado, in Board of Commissioners of Adams County v. City and County of Denver, recounted in detail the expert testimony offered by Adams County, that fatally undercuts the traditional reliance by the City of Denver, operator of Denver International Airport (“DIA”), and airport operators in general, on “noise modeling” in place of “noise monitoring” to determine the impacts of the aircraft noise on surrounding communities.

The Judgment exhaustively recounted evidence offered by Adams County, detailing the flaws in the noise modeling utilized by DIA to document compliance with the noise provisions of the “Intergovernmental Agreement [for a new airport], (‘IGA’),” originally entered into between the two parties on April 21, 1988, when the plan for development of the new Denver airport was being initiated.Continue Reading Colorado Court Judgment Finds Noise Modeling Significantly Understates Aircraft Noise

The Federal Aviation Administration (“FAA”) Reauthorization Act of 2018 (“Act”), passed by Congress on October 3, 2018, devotes an entire section, Title 1, Authorizations, subtitle D, to “Airport Noise and Environmental Streamlining.” Among the 22 provisions enacted by the subtitle, at least 12 deal directly or indirectly with aircraft noise. These provisions almost exclusively require “studies,” “research,” “consideration,” and “reports,” and notably lack, with only three exceptions, any mandate for substantive action.

In a marked change in longtime Federal Aviation Administration (“FAA”) policy regarding analysis of noise and air quality impacts from FAA initiated, directed or funded projects, FAA has substituted a single new model for the long mandated Integrated Noise Model (“INM”) and Emissions and Dispersion Modeling System (“EDMS”).  Beginning May 29, 2015, FAA policy “requires” the use of the Aviation Environmental Design Tool version 2b (“AEDT 2b”), which integrates analysis of aircraft noise, air pollutant emissions, and fuel burn.  These impacts, according to FAA are “interdependent and occur simultaneously throughout all phases of flight.”  80 Fed.Reg. 27853.  

 
The FAA policy provides for differential displacement of existing analytic models.  For air traffic and airspace procedural changes, AEDT 2b replaces AEDT 2a, already in use.  For other, ground based projects, AEDT 2b replaces both the INM, for analyzing aircraft noise, and EDMS for developing emissions inventories and modeling emissions dispersion.  The change was presaged by FAA Administrator Michael Huerta who announced in April that FAA was undertaking an “ambitious project” to revamp its approach to measuring noise.  The “ambitious project” was apparently inspired by the vocal objections to the results of the analysis using current methodologies, voiced by citizens of locals that have experienced the effects of FAA’s current, nationwide reorganization of airspace around major airports to institute procedures based on Performance Based Navigation (“PBN”).

In an unprecedented action aimed at limiting or eliminating noisy helicopters and fixed-wing aircraft from use of the East Hampton Airport, in East Hampton, Long Island, New York (“Airport”), on April 6, 2015, the East Hampton Town Board, operator of the airport, imposed strict noise limits, including a curfew, on the hitherto largely unregulated Airport.  The greatest source of the problem that has generated a flood of local noise complaints appears to be the increasing helicopter traffic that ferries well-to-do city dwellers and LaGuardia and Kennedy passengers who live on Long Island to the beach community.  The noise has apparently increased with the imposition of a new rule by the FAA requiring helicopters to fly off the North Shore of Long Island, and cross Long Island at, and into, East Hampton on the South Shore.  The proposed regulatory protocol is dramatic.  Continue Reading Town of East Hampton Explores Limits of Aircraft Noise Regulation

In a rare showing of unanimity between airport operator and noise impacted community, on September 30, 2014 the Board of Supervisors of Orange County, California (“Board”) approved the extension, for an additional 15 years, of a long-standing set of noise restrictions on the operation of John Wayne Airport (“Airport”), of which the Board is also the operator.  Those restrictions include: (1) limitation on the number of the noisiest aircraft that can operate at the Airport; (2) limitation on the number of passengers that can use the Airport annually; (3) limitation on the number of aircraft loading bridges; and, perhaps most important, (4) limitation on the hours of aircraft operation (10:00 p.m. to 7:00 a.m. on weekdays and 8:00 a.m. on Sundays).   

The restrictions were originally imposed in settlement of a lawsuit in 1986, between the Board, the neighboring City of Newport Beach and two environmental organizations, the Airport Working Group of Orange County, Inc. and Stop Polluting Our Newport.  The obvious question is whether similar restrictions might be achieved at other airports today. The not so obvious answer is that such a resolution is far more difficult now, but not impossible.

On December 4, 2013, Representative Joseph Crowley of a district in the Bronx and Queens, New York, heavily impacted by operations at LaGuardia Airport, introduced the “Quiet Skies Act” (H.R. 3650).  Supported by a variety of Congresspersons from other similarly impacted districts, the Act requires passenger airlines to replace or retrofit 25% of their fleets every five years until 2035 to meet a “Stage 4” standard, approximately 10 decibels lower than currently approved “Stage 3” engines. 

The conversion mandated by the Act might seem to result in significant relief to populations impacted by frequent overflights of Stage 3 aircraft.  There are, however, at least two conditions significantly vitiating the Act’s impacts.
