Re: Boston Logan International Airport 2018/2019 Environmental Data Report - EEA #3247 
Dear Secretary Theoharides and Director Kim: 
On behalf of the Massachusetts Port Authority (Massport), we are pleased to submit this 2018/2019 
Environmental Data Report (EDR) for Boston Logan International Airport. This filing continues 
Massport’s nearly four -decade practice of providing an extensive record of Logan Airport
environmental trends, facility planning, operations and passenger data, and Massport’s mitigation 
commitments. As a follow-up to the 2017 Environmental Status and Planning Report (ESPR) , and with 
the Secretary’s approval, this EDR combines reporting for 2018 and 2019. 
This EDR was prepared in 2020 during the ongoing COVID-19 worldwide pandemic. Accordingly,
Massport has strived to include relevant updates through fall 2020. The dramatic nature of the
COVID-19 pandemic, and its impacts to the broader world, the U.S. and local economies, and to the
aviation industry in particular, triggered a significant decline in Massport’s financial condition, 
causing deferrals to projects or programs that were in place in 2018 and 2019 and planned for 2020
and beyond. 
Beginning in March 2020, flights in and out of Logan Airport were dramatically reduced and
passenger levels dropped by over 90 percent at the peak of the pandemic in the spring and summer
of 2020. As a result, there are far fewer aircraft operations and passengers and a dramatic drop in
overall Logan Airport activity. While activity levels began a slow recovery in mid-summer 2020, the
ongoing wave of COVID-19 cases has resulted in continued historically low levels of activity, with a
full recovery years away. As of October 2020, total flight operations are down by 50 percent and
passenger levels are down by about 70 percent compared to 2019. Massport expects 2020 annual
passenger levels to have dropped to levels of activity not seen since the mid-1970s. 
As a result of this significant reduction in Airport activity and dramatic reduction in revenues, both
Massport and our airline and other tenants have adjusted their capital and operations plans.
Concurrently, the schedule for a number of Airport projects and programs have been revised
significantly. In an effort to be as transparent as possible, Chapter 3, Airport Planning includes the
most current project updates through October 2020.

Secretary Kathleen A. Theoharides Page 2 December 31, 2020 
The growth at Logan Airport that was experienced through early 2020 was tied closely to the strong
local, regional, national, and international economies and its role as the major airport to a region that
is the home to world-class educational and medical institutions, cutting-edge technology companies,
rich historical resources, and extensive tourism. Logan Airport ’s recovery and the timeframe once the 
COVID-19 pandemic ends will similarly be driven by the national and regional economic recovery. 
Massport continues to evaluate and plan for the recovery of aircraft operations and air passenger
activity and remains committed to implementing the broad range of environmental and operating
strategies designed to reduce the impacts associated with Airport operations. However, there is high
uncertainty regarding the duration of Massport’s financial crisis and the timing of flights, passenger,
and business recovery. As a result, the deferral of certain projects and programs will be evaluated on
an ongoing basis. Forthcoming EDRs will continue to provide operations, project, and programmatic
updates, as available. 
As we look forward, Massport will continue to seek opportunities to implement measures designed
to reduce Logan Airport ’s operating and environmental impacts. Such measures will be tied to High 
Occupancy Vehicle (HOV) strategies, noise abatement procedures, emission reduction and energy
efficiency measures, as well as continued information sharing with interested stakeholders and our
neighbors. Additionally, this EDR, in response to community input, includes an expansion of the
discussions on the evolving science and studies of aircraft noise and emissions and associated public
health investigations. Through both this EDR and future EDRs/ESPRs, we hope both to share most
recent, available information and, where possible, support those studies that will ultimately guide
evolving regulations and mitigation strategies. 
EDR Content and Structure 
The 2018/2019 EDR responds to the Secretary’s Certificate on the Boston Logan International Airport
2017 ESPR dated November 25, 2019. The EDR also updates 2018 and 2019 (and later where
available) conditions for the following categories: 
• Passenger levels, aircraft operations, aircraft fleets, and cargo volumes; 
• Planning, design, and construction activities at Logan Airport; 
• Regional transportation statistics and initiatives; 
• Key environmental indicators (Ground Access, Noise Abatement, Air Quality/Emissions
Reduction, and Environmental Compliance and Management/Water Quality); 
• Status of Logan Airport project mitigation; and 
• Sustainability initiatives. 
The 2018/2019 EDR includes the Secretary’s Certificate on the 2017 ESPR and associated comment
letters. Recent Certificates received on the Logan Airport Parking Project (EEA# 15665) and Terminal
E Modernization Project (EEA# 15434), which included items to be addressed in future EDRs and the
ESPR are also included. Appendix D, Distribution presents the EDR distribution list and supporting
technical appendices are included in the attached CD.

Secretary Kathleen A. Theoharides Page 3 December 31, 2020 
Review Period, Distribution, and Consultation 
Massport has requested EEA’s consideration of an extended 45-day public comment period for this EDR
in consideration of the multi-year nature of this document. Based on this request, the public comment
period will begin on January 6, 2021, the publication date of the next MEPA Environmental Monitor ,
and will end on February 22, 2021. The distribution list included as Appendix D indicates which listed
parties will receive a printed copy of this EDR or notice of availability with a link to the document on 
Massport’s website . As with the recent EDRs and other Massport environmental filings, this EDR is 
presented in its entirety on Massport’s website ( http://www.massport.com/massport/about-
massport/project-environmental-filings/ ). 
A public virtual consultation session on the 2018/2019 EDR will be planned for late January/early
February 2021. Details on the date of the meeting will be posted on Massport’s website at 
https://www.massport.com/massport/about-massport/project-environmental-filings/ . Additional

Introduction/Executive Summary 
Introduction 
The Massachusetts Port Authority (Massport) is continuing its nearly four-decade practice of providing an
extensive record of Boston Logan International Airport (Logan Airport or Airport) environmental trends, facility 
planning, operations and passenger levels, and Massport’s mitigation commitments in this Boston Logan
International Airport 2018/2019 Environmental Data Report (EDR) . As Massport has done periodically following
circulation and review of our Environmental Status and Planning Reports (ESPRs), with the approval of the
Secretary of the Massachusetts Executive Office of Energy and Environmental Affairs (EEA), this 2018/2019 EDR 
combines data and analysis for calendar years 2018 and 2019. 
This EDR was prepared in 2020 during the ongoing COVID-19 pandemic. Massport has strived to include relevant
updates through fall 2020 where the current conditions have resulted in changes in projects or programs that
were in place in 2018 and 2019. Beginning in March 2020, flights in and out of Logan Airport were dramatically
reduced and passenger levels dropped by over 90 percent at the peak of the pandemic in the spring and
summer of 2020. As a result, currently there are far fewer aircraft operations and passengers and a dramatic drop
in overall Logan Airport activity. While activity levels began a slow recovery in mid-summer 2020, the ongoing
wave of COVID-19 cases has resulted in continued historically low levels of activity, with a full recovery
anticipated years away. As of October 2020, total flight operations for the year were down by approximately
50 percent and passenger levels were down by about 70 percent compared to January through October 2019.
Massport expects that by the end of 2020, passenger levels will have dropped to levels of activity not seen since
the mid-1970s. 
Air traffic declines caused by economic recessions and other “shocks” such as the events of September 1 1, 2001
and the Great Recession in 2008/2009 have been followed by gradual recovery cycles. As depicted in Figure 1-1 , 
after the events of September 11, 2001 and the subsequent recession, Logan Airport’s passenger activity levels 
declined by about 18 perce nt, yet recovered five years later. Logan Airport’s passenger volumes declined by 
about 9 percent after the Great Recession of 2008/2009. As shown in Figure 1-2 , in 2020 the seven-day average
Transportation Security Administration (TSA) passenger screening throughput dropped by over 90 percent very
quickly. Figure 1-3 shows the percent change in monthly TSA throughput from 2019 to 2020 for the nation and
Boston. 
COVID-19 is having an unprecedented impact on not just the aviation industry but the global economy. While
the immediate and most pressing concern is human cost, COVID-19 has created profound implications for nearly
all businesses and industries. The impact on aviation has been particularly severe. The situation is changing on a
daily basis and there remains considerable uncertainty as to how long this pandemic will last and what will be the
long-term impacts.

Notes: Logan Airport terminal (left) and baggage claim area (right) during the COVID-19 pandemic. 
As a result of this significant reduction in Airport activity and dramatic reduction in revenues, both Massport and
our airlines and other tenants have necessarily adjusted and scaled back their operations. Concurrently, the
schedule for a number of Airport projects and programs have been revised and pushed back. To be as
transparent as possible, Chapter 3, Airport Planning includes the most current project updates through October
2020. Forthcoming EDRs will continue to provide updates, as available. Overall, Massport continues to evaluate
and plan for the recovery of aircraft operations and air passenger activity and remains committed to
implementing the broad range of environmental and operating strategies designed to reduce the impacts
associated with Airport operations.

Logan Airport, owned and operated by Massport, plays a key role in the metropolitan Boston and New England
passenger and freight transportation networks; it is the primary airport serving the Boston metropolitan area, the
principal New England airport for long-haul services, and a major U.S. international gateway airport for
transatlantic services. The Airport boundary encompasses approximately 2,400 acres in East Boston and
Winthrop, including approximately 700 acres in Boston Harbor. Logan Airport’s airfield comprises six runways, 
approximately 15 miles of taxiway, and approximately 240 acres of concrete and asphalt apron. Logan Airport has
four interconnected passenger terminals (Terminals A, B, C, and E), each with its own ticketing, baggage claim,

and ground transportation facilities. The Airport is less than a three-mile drive from downtown Boston and is
accessible by public transit lines, several direct bus lines, and a well-connected roadway system. Massport
provides Logan Express bus service to and from Logan Airport for air passengers and employees from a series of
park-and-ride lots. 
This 2018/2019 EDR is one in a series of annual environmental review documents submitted to the Secretary of
EEA, in accordance with the Massachusetts Environmental Policy Act (MEPA). 1 Since 1979, Massport has
submitted these documents to report on the cumulative environmental effects of Logan Airport’s operations and 
activities. Logan Airport is the first airport in the nation for which an annual environmental assessment on airport
activities was prepared, and Massport continues to be a leader in environmental reporting. 
Approximately every five years, Massport prepares an ESPR, which provides a historical and prospective view of
Logan Airport. EDRs, prepared annually in the intervals between ESPRs, provide an historical review of
environmental conditions for the reporting year compared to the previous year. This 2018/2019 EDR follows the 
2017 ESPR which reported on 2017 conditions and included projections and analyses of future operating and
environmental conditions based on a pre-COVID-19 passenger forecast. While Massport and the entire aviation
industry continue to adjust to the new operating conditions, we continue to evaluate the pandemic ’ s current and
future impacts. Where possible, this EDR includes relevant information and updates. However, more detailed
projections and analyses will necessarily need to be addressed in future ESPRs. 
The scope for this combined 2018/2019 EDR was established by the Secretary‘s Certificate on the 2017 ESPR 
dated November 25, 2019, which is included in Appendix A, MEPA Certificates and Responses to Comments . This 
EDR fulfills all the requirements laid out in the Secretary’s Certificate on the 2017 ESPR and includes responses to
comments on the Secretary’s Certificate and updates and compares the data presented in the 2017 ESPR for the
following subjects: 
To enhance the usefulness of this EDR as a reference document for reviewers, this report also presents historical
data on the environmental conditions at Logan Airport dating back to 1990, in instances where historical
information is available. When appropriate and available, this EDR also includes updates through fall 2020.

Logan Airport Environmental Review Process 
This 2018/2019 EDR is Massport’s next filing in its unique, but well-established, formal state-level environmental
review process that assesses Logan Airport’s cumulative environmental impacts. The documents provide a
current and historical context against which individual projects at Logan Airport meeting state and federal
environmental review thresholds are evaluated on a project-specific basis. The Airport-wide and project-specific
environmental review processes are described below.

In 1979, the Secretary of EEA issued a Certificate requiring Massport to define, evaluate, and disclose every three
years the impact of long-term growth at the Airport through a Generic Environmental Impact Report (GEIR). The
Certificate also required interim Annual Updates to provide data on conditions for the years between GEIRs. The
GEIR evolved into an effective planning tool for Massport and provided projections of environmental conditions
so that the cumulative effects of individual projects could be evaluated within a broader context. 
EEA eliminated GEIRs following the 1998 revisions to its MEPA r egulations. However, the Secretary’s Certificate 
on the 1997 Annual Update 2 proposed a revised environmental review process for Logan Airport resulting in 
Massport’s preparation of subsequent EDRs/ESPRs. The more comprehensive ESPRs provide a long-range
analysis of projected operations, passengers, and cumulative impacts, while EDRs are prepared annually to
provide a review of environmental conditions for the reporting year compared to the previous year. The
EDR/ESPR process was developed to allow individual projects at Logan Airport to be considered and analyzed in
the broader, Airport-wide context. As stated in the introduction to the 1999 ESPR , “while the Logan ESPR and 
EDRs provide the broad planning context for projects proposed for Logan Airport and future planning concepts
under consideration by Massport, no specific projects can be built solely on the basis of inclusion and discussion

October 16, 1998.

Introduction/Executive Summary 1-6 
in the 1999 ESPR.” It continues to state that projects that meet MEPA or NEPA review thresholds must undergo
those processes, as needed. In short, the EDRs/ESPRs provide a cumulative planning context which complements
the individual project-specific filings. 
In 2018 and 2019, while passenger levels experienced significant growth, reaching new peaks, aircraft operations
and associated environmental effects remained well below levels previously analyzed for Logan Airport. Thus, the
forecasted aviation growth presented in the 2004 ESPR , the predicate upon which the ESPR schedule was initially
established, has not occurred. Accordingly, with the approval of the Secretary, Massport prepared 2009 and 2010
EDRs in lieu of the ESPR originally planned for 2009. The 2011 ESPR , filed in early 2013, reported on calendar year
2011 and updated passenger activity level and aircraft operations forecasts. The combined 2012/2013 EDR 
presented conditions for both calendar years 2012 and 2013. The 2014 EDR , 2015 EDR , and 2016 EDR presented
conditions for calendar years 2014, 2015, and 2016, respectively. Similarly, with strong passenger growth and
evolving ground access trends with the emerging RideApp industry (formerly referred to as transportation
network companies [TNCs]), EEA allowed Massport to defer the 2016 ESPR . 
The 2017 ESPR provided a comprehensive, cumulative analysis of activity levels and environmental conditions for
2017 and a Future Planning Horizon. In the ESPR, Massport proposed preparation of a combined 2018/2019 EDR 
to report the effects of all Logan Airport activities based on actual passenger activity and aircraft operations in
2018 and 2019. This document responds to EEA approval of the combined 2018/2019 EDR . 
While this report is largely focused on 2018 and 2019, Massport has included the best available information on
2020 as the Authority and the nation react to the COVID-19 pandemic. Where appropriate, Massport will
continue to identify and address any longer-term aviation and environmental trends in both EDRs and ESPRs.
Project-Specific Review 
While this Airport-wide review provides the broad planning context for proposed projects and future planning
concepts, certain Airport projects are also subject to a project-specific, public environmental review process when
they meet state environmental review thresholds. When required, Massport and Airport tenants submit
Environmental Notification Forms (ENFs) and Environmental Impact Reports (EIRs) pursuant to MEPA. Similarly,
where NEPA 3 environmental review is triggered, projects are reviewed under the NEPA environmental review
process. Current and potential future projects anticipated to undergo MEPA and/or NEPA review are discussed in
Chapter 3, Airport Planning . 
Logan Airport Planning Context 
Logan Airport plays a key role in the metropolitan Boston and New England passenger and freight transportation
networks. The Airport is one of the most land-constrained airports in the nation and is surrounded on three sides
by Boston Harbor (see Figures 1-4 and 1-5 ).

Passenger and Aircraft Activity Growth at Logan Airport 
In 2019, air passenger activity levels at Logan Airport reached an all-time high of 42.5 million, an increase
of 3.9 percent over 2018 (40.9 million). As has been the recent trend prior to March 2020, aircraft
operations increased at a slower rate than passengers. In 2019, operations totaled 427,176 and 2018
operations totaled 424,024. These levels both represent increases compared to the 2017 passenger levels
of 38.4 million and 401,371 operations ( Figure 1-6 ). The growth seen during 2018 and 2019 was directly
correlated to the strong national and regional economies. Even with this strong growth, aircraft
operations remained well below the 487,996 operations in 2000 and the historic peak of 507,449
operations reached in 1998. The slower growth in aircraft operations compared to passenger levels is due
to the steady increase in aircraft size and improving aircraft load factors (passengers/available seats).

Introduction/Executive Summary 1-10 
Logan Airport Activity Levels are Closely Tied to the Regional and
National Economy 
Activity levels at Logan Airport are largely driven by the local, regional, and national economies. As can be
seen by looking at long-term trends, it is clear that when the economy is strong, Logan Airport grows.
Similarly, the most significant declines in passenger levels and aircraft operation track closely with
significant national and international disruptions. Examples of the most significant declines include the
Professional Air Traffic Controllers Organization (PATCO) strike in 1981, September 11, 2001, the Great
Recession in 2008/2009, and now the COVID-19 pandemic. 
When there has been significant growth, as was observed through 2018 and 2019, Massport has
implemented strategies to address that growth in a manner that allows Logan Airport to evolve in a
sustainable and environmentally responsible way. 
Logan Airport is the largest airport in the six-state New England region, which has a population of
approximately 14.8 million residents. The Airport is located in Massachusetts, which is home to 6.9 million
residents, or nearly 46 percent of New England ’s population. Logan Airport serves passengers from across
New England, with its primary catchment area consisting of five Massachusetts counties: Essex, Middlesex,
Norfolk, Plymouth, and Suffolk (which includes the City of Boston). According to the most recently
available statistics, 4.4 million people reside in this five-county area, and population within the catchment
area is projected to increase by 0.5 percent per year over the next 19 years. 4 In 2019, similar to past years,
the Boston metropolitan area maintained a lower unemployment rate (2.6 percent) than that of the
Commonwealth (2.9 percent) and the entire country (3.7 percent). 5 The Airport not only serves a growing
population, but a high earning one as well. Per capita income in 2019 was $68,361 (2012 U.S. dollars) in 
the Airport’s primary service area, 3.6 percent higher than the Commonwealth and 35.9 percent higher
than the national average. 6 
Logan Airport is a key transportation and economic resource in the New England region, the state, and
the Boston metropolitan area, which is home to a broad range of industries. The industries accounting for
the largest share of employees include: healthcare and social assistance; educational services; and 
professional, scientific, and technology services (which include Boston’s thriving biotech industry). 7 In 2018
and 2019, Boston was ranked the #1 city in the U.S. for education and #2 in healthcare. 8 The contribution
of innovation and business start-ups is also evident in the latest 2019 economic growth estimates. 
In addition to supporting the growth and economic success of the state, Logan Airport and the airport
industry are important elements in the state and regional economy. The Massachusetts Statewide Airport

(MassDOT) in 2014 and most recently updated in 2019, 9 estimates that Massport airports – inclusive of
Logan Airport, Worcester Regional Airport, and Hanscom Field – contribute approximately $23.1 billion in
output to the Massachusetts economy annually; of this output, 71 percent is due to Logan Airport alone. 10 
Total output includes on-Airport businesses, construction, visitor, and multiplier effects (see Figure 1-7 ). 11 
Logan Airport supports over 162,000 direct and indirect jobs, while generating approximately $16.3 billion
per year in total economic output. 12 In 2019, over 23,000 people were employed at Logan Airport. This
included approximately 820 Massport Logan Airport staff and additional administrative employees. 13

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-12 
Logan Airport is considered an origin and destination (O&D) 14 airport both nationally and internationally,
meaning that approximately 90 percent of Logan Airport passengers ’ trips either start or end at Logan
Airport. Hub airports, such as Atlanta or Chicago, serve many more passengers annually but, compared to
O&D airports like Logan Airport, a higher percentage of passenger traffic at hub airports passes through
to connecting flights. Through 2019, Logan Airport was one of the fastest growing large airports in the
United States in terms of passenger volume. 15 From 2017 to 2019, U.S. air passenger traffic grew by
9.1 percent, whereas Logan Airport experienced a passenger growth of 10.7 percent over the same time
period. 16 Logan Airport is considered a domestic and international origin and destination (O&D) airport,
meaning that less than 10 percent of air passengers are connecting through Logan Airport. 
Forecast Status 
The 2017 ESPR presented an updated forecast for Logan Airport aircraft operations and passenger activity.
That forecast focused on a Future Planning Horizon including a projected 50 million annual air passengers
and 486,000 annual aircraft operations . Massport’s ESPR forecast was consistent with the Federal Aviation 
Administration’s (FAA’s) Terminal Area Forecast at that time. However, the COVID-19 pandemic has
dramatically reduced air passenger traffic and it ’ s currently expected that it will take several years for the
industry to return to pre-COVID-19 operational levels. 
During 2018 and 2019, due to the strong economy, passenger activity levels and aircraft operations at
Logan Airport increased rapidly. This growth trend was upended in March 2020 and accordingly, the 
2017 ESPR projections will need to be adjusted as the longer-term impacts of the COVID-19 pandemic are
better understood. 
Massport Investment in Logan Airport 
Massport evaluates and implements enhancements to Logan Airport’s safety, security, operational 
efficiency, and accessibility to and from the Boston metropolitan area, while carefully monitoring the
environmental effects of Logan Airport operations. A continuing focus has been on enhancing the
passenger and user experience at Logan Airport. Recent and ongoing terminal area projects are aimed at
providing seamless post-security connectivity among the terminals along with enhancements to
passenger processing through consolidated security checking areas. Access to and around Logan Airport
also remains a priority. Massport continues to work with FAA to enhance airside safety through a variety
of runway safety area (RSA) improvements and simplification of the airfield geometry. 
As noted above, the impacts of the COVID-19 pandemic have precipitated a wide range of changes at
Logan Airport. Both the drop in passengers and associated revenues have required significant 
14 “Origin and destination” traffic refers to the passenger traffic that either originates or ends at a particular airport or mark et. A
strong O&D market like Boston generates significant local passenger demand, with many passengers starting their journey and
ending their journey in that market. O&D traffic is distinct from connecting traffic, which refers to the passenger traffic that
does not originate or end at the airport but merely connects through the airport en route to another destination. 
15 Between 2014 and 2019, Logan Airport was the 20th fastest growing airport in the U.S. in terms of domestic O&D traffic
compared to the top 30 large hub U.S. airports (U.S. DOT O&D Survey).

adjustments to services and project schedules. Massport has focused on adjusting services to match the
shifting passenger levels and ensure that those changes are made with careful consideration of managing
environmental and operating impacts. In some areas, programs have been adjusted to reflect current
needs and impacts. Massport remains committed to implementing project-related mitigation strategies,
as documented in Chapter 9, Environmentally Beneficial Measures and Project Mitigation Tracking . 
2018 and 2019 Highlights and Key Findings 
This section provides a brief overview of key findings, by chapter, at Logan Airport in 2018 and 2019. A
brief update on 2020 activity and future projections is also included in light of the COVID-19 pandemic.
Additional information concerning Airport activities is provided in subsequent chapters. This section also
highlights Massport’s efforts to further sustainability through specific projects and initiatives with a 
sustainability leaf and summarizes Massport’s sustainability program. 
The Secretary’s Certificate on the 2017 ESPR , which forms the Scope of this 2018/2019 EDR ,
acknowledged the rapid growth in the past several years and directed Massport to provide updates on
the 2017 ESPR forecast. While Logan Airport’s recent rapid passenger growth continued through early 
2020, the COVID-19 pandemic began to dramatically reduce airport operations and passengers in mid-
March 2020. In the early phases of the pandemic, passenger levels dropped by over 90 percent. While
activity levels began a slow recovery in mid-summer 2020, the ongoing wave of COVID-19 cases has
resulted in continued historically low levels of activity, with a full recovery years away. As of October 2020,
total flight operations for the year were down by 50 percent and passenger levels were down by about
70 percent compared to January through October 2019. Massport expects that by the end of 2020,
passenger levels will have dropped to levels of activity not seen since the mid-1970s. Until the longer-
term impacts of COVID-19 are better understood, Massport can only make preliminary projections of the
rate of recovery for passenger levels. The next EDR will provide further updates using best available
information at that time. 
Activity Levels 
Until the onset of the COVID-19 pandemic, Logan Airport (and the aviation industry in general) had been
experiencing strong growth, largely driven by the positive economic conditions in the Boston region, low
unemployment, a strong, diverse economic base, and continued investment in commercial and residential
real estate, particularly in life sciences, finance, healthcare, and higher education. Due to the COVID-19
pandemic, 2020 passenger levels and operations have dramatically decreased. As of October 2020, year-
over-year passenger levels and operations are down by approximately 70 percent and 50 percent,
respectively. 
Air passenger activity levels at Logan Airport in 2018 and 2019 increased to 40.9 million in 2018 and
42.5 million in 2019. Aircraft operations continued the long-term trend of increasing at a slower rate than
passengers. In 2018, operations totaled 424,024 and 2019 operations totaled 427,176. That growth was
directly correlated to the strong national and regional economy. Even with the strong growth, aircraft
operations remained well below the 487,996 operations in 2000 and the historic peak of

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-14 
507,449 operations reached in 1998. The combination of fewer operations in cleaner and quieter aircraft
has resulted in dramatically reduced environmental impacts when compared with those historical peaks. 
From 2010 to 2019, the annual number of passengers at Logan Airport increased by about 55 percent,
while the annual number of aircraft operations 17 increased at a slower rate, about 21 percent, due to
increasing aircraft load factors. International passenger levels increased at a faster rate than domestic
passenger levels in 2018 and 2019. Domestic air passenger activity levels increased by 6.9 and 2.6 percent
in 2018 and 2019, respectively, while international air passenger activity levels increased by 5.3 and
9.7 percent, respectively. 
Please see Chapter 2, Activity Levels, for additional information. 
Airport Planning 
Massport is continually improving the facilities at Logan Airport to accommodate changes in passenger
demand, aircraft activity, cargo needs, and transportation access. In Chapter 3, Airport Planning , Massport
has identified priority planning projects and initiatives in the following categories: 
▪ Ground Transportation and Parking; 
▪ Terminals; 
▪ Airside Planning; 
▪ Service Areas; 
▪ Airport Buffers and Open Space; and 
▪ Energy, Sustainability, and Resiliency. 
During 2018 and 2019 there was a strong focus on ground access and trip reduction measures and
terminal improvements. Recent and ongoing terminal area projects are providing seamless post-security
connectivity and flexibility among the terminals along with enhancements to passenger processing
through consolidated security checking areas. 
To enhance the on-Airport roadway network, Massport is improving several of the terminal area roadway
segments and intersections. In October 2019, Massport opened its new RideApp consolidated drop-off
and pick-up areas in the Central Garage. In 2018 and 2019, Massport also advanced several high-
occupancy vehicle (HOV) services and Logan Express facilities improvements as part of its trip-reduction
goals. 
17 An aircraft operation is defined as one arrival or one departure.

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-15 
Since filing the 2017 ESPR , Massport has completed state and/or federal environmental review of several
projects: 
▪ The Logan Airport Parking Project, which will add 5,000 commercial parking spaces at Logan Airport
in locations already in use for parking. The additional parking spaces respond to the MassDOT and
U.S. Environmental Protection Agency (EPA) ’s approval of a modification to the regulatory Logan
Airport Parking Freeze. 18 The additional spaces are intended to reduce environmentally harmful drop-
off/pick-up modes (i.e., dropped off or picked up by private vehicles, taxi, RideApp, or black car
limousine service). The joint MEPA/NEPA review process was completed in January 2020. This project
is currently deferred due to the reduction in passenger activity associated with the COVID-19
pandemic. 
▪ Terminal C Canopy, Connector and Roadway Project received federal environmental approval under
NEPA in November 2018. As described in the 2017 ESPR , construction of this project will replace and
reconfigure sections of the elevated roadways connecting Terminals B and C. At this time,
construction of the replacement canopy is anticipated to begin and be completed in 2021, with a
slightly reduced program than originally planned. The Terminal B to C Connector is anticipated to be
complete in spring 2022 and roadways are anticipated to be complete in 2023. 
Massport continues to work with FAA to enhance airside safety through a variety of federal Runway Safety
Area projects and simplification of the airfield geometry. Please see Chapter 3, Airport Planning, for
additional information. 
Regional Transportation 
In 2018 and 2019, the New England region saw an increase in air passenger activity. Regional air
passengers increased by 6.5 percent to 58.3 million air passengers in 2018 and then another 2.5 percent
to 59.7 million in 2019. The 10 regional airports (excluding Logan Airport) in New England accommodated
17.3 and 17.2 million air passengers in 2018 and 2019, respectively, compared to 16.3 million passengers
in 2017. 
Worcester Regional Airport, T.F. Green Airport, Portland International Jetport, Burlington International
Airport, and Bangor International Airport saw an overall increase in commercial service operations since
2017. Manchester-Boston Regional, Tweed-New Haven, Bradley International, and Portsmouth
International airports saw reduced service offerings since 2017. 
Massport’s three airports, Logan Airport, Worcester Regional Airport, and Hanscom Field, make significant
contributions to the regional economy, generating approximately $23.1 billion annually, or 94 percent of
the overall economic benefits generated by the Massachusetts airport system. Hanscom Field is a reliever
airport to Logan Airport and is the second busiest airport in New England. 
Worcester Regional Airport passenger numbers increased by 76 percent in 2019 compared to 2017 and
reported a total of 817,057 passengers from 2013 to 2019. In the past five years, Worcester Regional
Airport experienced an average growth rate of 10 percent per year. Massport continues to invest in 
18 310 Code of Massachusetts Regulations 7.30 and 40 Code of Federal Regulations 52.1120.

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-16 
Worcester Regional Airport — together with the City of Worcester, Massport has already initiated a
$100 million, 10-year investment to revitalize and attract commercial operations to Worcester Regional
Airport. Investments include a CAT III Instrument Landing System (about $32 million) paid for by federal
grants and Massport funds. Additionally, jetBlue Airways, American Airlines, and Delta Air Lines
announced new service to New York John F. Kennedy International Airport (JFK), Philadelphia International
Airport, and Detroit Metropolitan Wayne County Airport, respectively. As of the publication date of this
EDR, commercial passenger service out of Worcester Regional Airport has been suspended by the airlines
due to a drop in passenger demand as a result of the COVID-19 pandemic. 
Amtrak rail system-wide ridership increased from 31.7 million customer trips in fiscal year (FY) 2018 to
32.5 million trips in FY 2019. In FY 2018, the Northeast Corridor (NEC) carried over 12 million passengers,
up about 1 percent from the prior year. In FY 2019, the NEC carried 12.5 million passengers on those
services, up about 3 percent from the prior year. 
Ground Access 
Logan Airport continues to be one of the top airports in the United States in terms of HOV and transit
mode share. Massport promotes numerous HOV, transit, and shared-ride options to improve on Airport
roadway and curbside operations, alleviate constraints on parking, and improve customer service. Key
findings from 2018 and 2019 are summarized in the bullets that follow and additional details can be
found in Chapter 5, Ground Access to and from Logan Airport. 
▪ Average weekday on-Airport vehicle miles traveled (VMT) increased by about 4.5 percent from 2017
to 2018. Between 2018 and 2019, average weekday on-Airport VMT increased by 2.2 percent. The
change in average daily traffic can be attributed primarily to the increases in air passenger activity,
passenger drop-off/pick-up, cargo, and non-aviation related Airport uses. It is anticipated that the
Airport activity and on-Airport VMT will be significantly lower in 2020 due to the impact of COVID-19. 
▪ RideApp transactions totaled more than 7 million in 2018 and increased to over 8 million in 2019, a
growth of over 16 percent. RideApps are impacting other access modes to the Airport and
contributing to on-Airport congestion. Partially due to the continued rise of RideApps, black car
limousines and scheduled van ridership dropped by nearly 23 percent from 2017 to 2019. Taxi
dispatches declined 14 percent in 2018 compared to 2017 and 7 percent between 2018 and 2019. The
Massachusetts Bay Transportation Authority (MBTA) Blue Line ridership increased by 4 percent
between 2017 and 2018 and declined by 29 percent the following year. 
▪ Based on changes in passenger mode choice for accessing Logan Airport observed between 2017 and
2019, Massport updated its goals and definition of HOV. The updated definition considers vehicle
occupancies of taxis, black car limousines, and RideApps that carry two or more air passenger per
vehicle to be HOV, while the same modes with one air passenger will count as non-HOV. With this
updated definition, Massport established a goal of 35.5 percent HOV by 2022 and 40 percent by 2027.
Based on the results of the 2019 Air Passenger Ground-Access Survey, HOV mode share has reached
40.4 percent, exceeding both near-term and longer- term goals. While it’s anticipated that the HOV 
mode share will drop as a result of COVID-19 over the short term, Massport expects HOV ridership to
recover over time and remains committed to the HOV mode share goals going forward.

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-17 
Ground Access Strategy 
Massport has a long-standing multi-pronged, trip reduction strategy to diversify and enhance ground
transportation options for passengers and employees traveling to and from Logan Airport. The strategy is
designed to offer passengers a choice of HOV, transit, and shared-ride options that are convenient and
reliable, and that reduce environmental and community impacts. For many years, Logan Airport has
ranked as one of the top U.S. airports in terms of HOV and transit mode share. Massport promotes
numerous HOV, transit, and shared-ride options to improve on Airport roadway and curbside operations,
alleviate constraints on parking, and improve customer service. 
Massport’s strategy also aims to provide sufficient on-Airport parking for air passengers choosing
automobile access modes and/or who have limited HOV options. In 2017, the MassDEP amended the
Logan Airport Parking Freeze to allow for an increase of up to 5,000 on-Airport commercial parking
spaces, which allows for the construction of additional parking to reduce the use of drop-off/pick up
modes and alleviate constrained on-Airport parking conditions. 
A long-standing Massport interest is addressing on-Airport roadway congestion with a combination of
policy changes and infrastructure improvements. Alleviating terminal area congestion is important for
continued safe and efficient landside operations and to reduce environmental impacts. Enhancing
multimodal transportation options and providing modern, flexible infrastructure is one way an airport can
reduce greenhouse gas (GHG) emissions and improve its environmental footprint. 
Massport recognizes the importance of providing safe and reliable HOV services to and from the Airport
and by 2019 had already reached its strategic plan to increase HOV mode share to 40 percent by 2027.
Understanding the growth in RideApp use and their impact on regional and terminal area roadway
congestion is essential to managing on-Airport traffic volume and promoting HOV services as a viable
and attractive alternative. Potential emissions reductions are one reason why Massport is committed to a
long-term goal of promoting and supporting public and private HOV and shared-ride services aimed at
serving air passengers, Airport users, and employees. Other benefits include: 
▪ Reducing congestion on the terminal roadways and curbside drop-off/pick-up areas; 
▪ Alleviating constraints on limited parking facilities; and 
▪ Customer service (providing a range of transportation options for different traveler
demographics). 
While this report focuses primarily on activity in 2018 and 2019, as a result of the COVID-19 pandemic, a 
number of Massport’s broad HOV and trip reduction measures temporarily changed in 2020. Flights in 
and out of Logan Airport have been dramatically reduced and passenger levels dropped by nearly
90 percent beginning in March 2020. As a result, while operational and passenger levels have recovered
somewhat as of mid-2020, overall, there are far fewer passengers and employees traveling to and from
Logan Airport and there is far less peak period roadway congestion both in Boston and the metropolitan 
area. In addition, the public’s interest in using HOV transportation services like buses, rapid transit , and
commuter rail has been significantly affected by public health concerns related to COVID-19. 
Within that context, Massport continues to evaluate and plan for the recovery of air passenger activity and
remains committed to implementing the broad range of ground access strategies that were outlined in

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-18 
the 2017 ESPR as demand for those measures recovers. The schedule for those services and planned
improvements has, however, been adjusted due to the continuing operational constraints and revenue
reductions. Massport continues to carefully review both on and off-Airport activity levels and will adjust its
ground access programs to align with ridership levels. Future EDRs will provide detailed updates on all
service adjustments and activity levels. 
Massport continuously evaluates it strategies and programs aimed at improving and, where needed,
expanding HOV services to and from Logan Airport, including continued investment in Logan Express
facilities and service. The initiatives described below can improve roadway operations as well as air quality
emissions. The following measures have been implemented or remain under consideration: 
▪ A goal to double Logan Express ridership by the time Logan Airport reaches 50 million air
passengers by expanding parking, frequency, and facility upgrades; 
▪ Suburban Logan Express Service Enhancements 
▪ In 2019, Massport increased total Logan Express seat capacity by over 10 percent. 
▪ Increase Braintree Logan Express service from two to three trips per hour (implemented in
May 2019 but reduced to hourly service in March 2020 due to the impacts of COVID-19). 
▪ Add about 1,000 additional spaces to the Framingham garage (permitting completed in
2020 however construction is deferred). 
▪ Provide security line priority status to Logan Express Back Bay riders (implemented in
2019; this service is temporarily suspended due to COVID-19). 
▪ Marketing to support Logan Express strategy and increase ridership. 
▪ Implement Logan Express electronic ticketing (pending). 
▪ Evaluate new Logan Express suburban locations, with a plan to open at least one new site
(deferred due to COVID-19). 
▪ Explore RideApp Last Mile connections. 19 
▪ Continue to monitor parking capacity at all Logan Express sites. 
▪ MBTA Silver Line 
▪ Eight MBTA Silver Line buses were purchased in 2005 by Massport and are operated by 
the MBTA, with Massport paying operating costs. Since the existing Silver Line fleet is
reaching the end of its useable life, the MBTA and Massport have been working together
on a plan to procure a replacement Silver Line fleet. As part of this initiative, Massport
and the MBTA developed a Silver Line Capacity Study to determine the mid-term fleet
and facility needs as well as to assess other ways to improve the reliability and capacity of
the system. Based on this analysis, the MBTA plans to procure 45 new enhanced electric
hybrid vehicles to replace the existing fleet of 32 dual mode vehicles. Massport plans to
purchase eight MBTA Silver Line buses as part of a forthcoming MBTA procurement. 
19 Individuals who fall within the 0.5-mile to 1-mile drive distance of a Logan Express facility are the most likely group to use TNCs
to connect between the facility and their home.

Noise 
Massport strives to minimize the noise effects of Logan Airport operations on its neighbors through a
variety of noise abatement programs, procedures, studies, and other tools. At Logan Airport, Massport
implements one of the oldest and most extensive noise abatement programs of any airport in the nation. 
Massport’s c omprehensive noise abatement program includes a dedicated Noise Abatement Office; a
state-of-the-art Noise and Operations Monitoring System (NOMS); extensive residential and school sound
insulation programs; time-of-day and runway restrictions for noisier aircraft; ground run-up procedures;
and flight tracks designed to optimize over-water operations (especially during nighttime hours). The 
public can register noise complaints by phone or online through Massport’s website. 21 
Key findings are summarized in the bullets that follow and additional details can be found in Chapter 6, 
Noise Abatement. 
▪ The fleet mix of Logan Airport continues to be composed of aircraft types with the quietest available
technology (Stage 5 is the quietest). About 15 percent of 2018 and 2019 operations were conducted
in aircraft meeting Stage 5 requirements, 83 percent meeting Stage 4 requirements, and 2 percent in
Certified Stage 3. While the shift to an all-Stage-4-and-5 fleet has been gradual, the accelerated
retirements of older aircraft in 2020 are likely to increase the share of Stage 5 in the Logan Airport
fleet. The retirement of older, noisier aircraft has been accelerated by the COVID-19 pandemic where
airlines continue to phase out older aircraft in response to reduced passenger loads beginning in
spring 2020. The 2020 EDR will provide an update on this emerging trend. 
▪ Massport and FAA continue to work with the Massachusetts Institute of Technology (MIT) to
investigate opportunities to reduce noise through changes to performance-based navigation (PBN),
including RNAV. This cooperation is a first-in-the-nation project between FAA and an airport operator
to better understand the implications of PBN and evaluate strategies to address community concerns. 
▪ Massport continues to be a national leader in sound insulation mitigation. To date, Massport has
provided sound insulation for a total of 36 schools and 11,515 residential units and will continue to
seek funding for mitigation for properties that are eligible and whose owners have chosen to
participate. Since the start of the program, over $170 million has been invested. In 2019, Massport
updated its Residential Sound Insulation Program (RSIP) Noise Exposure Map contours and submitted
an Aviation Environmental Design Tool (AEDT)-derived noise exposure map to the FAA in 2020 for
review and discussion. 
▪ Massport is currently working with FAA to possibly address issue with the first-generation sound
insulation windows. In January 2020, Massport ’s CEO sent a letter to the FAA Associate Administrator
requesting that Massport and FAA work together to address re-treatment of homes that were sound
insulated during the early years of the program to upgrade eligible homes to newer, more effective
and durable materials. The Associate Administrator responded that FAA is exploring limited
circumstances under which Massport might be able to mitigate homes that had been mitigated
before FAA first issued sound insulation standards in 1993. The status of the initiative will be reported
in future EDRs. Please see Appendix H, Noise Abatement for additional info.

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-21 
▪ Nighttime operations represented 16.1 percent and 16.6 percent of total operations in 2018 and 2019,
respectively. Nighttime operations increased, from an average of 168 per night in 2017 to 187 per
night in 2018 and 195 per night in 2019. The main increases to nighttime commercial activity were in
passenger aircraft operations, primarily resulting from the overall growth in domestic air carrier flights
and increased flights to international destinations. The majority (about 81 percent) of nighttime
operations occurred either before midnight or after 5:00 AM. 
▪ There was an overall decrease in the total number of people residing within the Day-Night Average
Sound Level (DNL) 65 decibel (dB) contour from 2017 to 2018. However, the number within the DNL
65 dB contour increased in Winthrop and Revere while decreasing in East Boston. From 2017 to 2018,
there was an increase in total operations and in nighttime operations, but the primary factor in the
DNL contour changes was a shift in 2018 back to typical runway use following the extended Runway
4L-22R closure in 2017. 
▪ The 2019 DNL contours are similar in shape and size to those for 2018, with small changes due to
runway use shifts, increases in nighttime operations, and overall operations growth in 2019. The total
number of people residing within the DNL 65 dB contour increased from 7,034 in 2018 to 8,768 in
2019. The additional population within the DNL 65 dB contour is mainly located in East Boston,
primarily due to an increase in Runway 33L departures due to an increase in northwest winds in 2019. 
▪ Compared to 1990, the total number of people residing in the DNL 65 dB contour is about 84 percent
lower and 80 percent lower in 2018 and 2019, respectively, due to improved engine technology. 
Noise Strategy 
The foundation of Massport’s noise program is the Logan Airport
Noise Abatement Rules and Regulations 22 (Noise Rules), which
have been in effect since 1986. Massport ’s Noise Abatement
Office is responsible for implementing noise abatement
measures and generally monitoring community complaints and
other aspects of the noise effects from Logan Airport operations. 
Massport is focused on the following noise abatement initiatives: 
▪ Partnerships with Airlines and FAA 
▪ Massport is encouraging retrofitting the Airbus
A319/320/321 family of aircraft with vortex 
generators, which reduce tonal noise on approach. In October 2018, jetBlue Airways (the air
carrier with the greatest number of operations at Logan Airport) announced plans to retrofit
its older Airbus fleet with Vortex Generators. This move reflects the partnership between
Massport and the airlines to reduce aircraft noise to benefit surrounding communities. As
airlines retrofit aircraft and transition to the newer models of the A320 family, the number of
aircraft operating at Logan Airport without the vortex generators is expected to decrease. For
more information, please refer to a press release discussing the generators in Chapter 6, 
Noise Abatement . 
22 The Logan International Airport Noise Abatement Rules and Regulations, effective July 1, 1986, are codified as 740 Code of
Massachusetts Regulations (CMR) 24.00 et seq (also known as the Noise Rules).

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-22 
▪ On October 7, 2016, Massport and FAA signed a Memorandum of Understanding (MOU) 23 to
frame the process for analyzing opportunities to reduce noise through changes or
amendments to performance-based navigation (PBN), including area navigation (RNAV). This
cooperation is a first-in-the-nation project between FAA and an airport operator to better
understand the implications of PBN and evaluate strategies to address community concerns.
MIT is the technical lead. Block 1 was completed in late 2017 and recommendations were
made to the FAA. Currently, MIT is conducting the analysis for Block 2. 
▪ The fleet operating at Logan Airport is comprised of 83 percent Stage 4 aircraft and
15 percent Stage 5 aircraft (Stage 5 being the quietest), well above the FAA minimum
Stage 3 engines. 
▪ Massport continues to prohibit the use of Runways 4L for departures and Runway 22R for
arrivals from 11:00 PM to 6:00 AM; maximize late-night over-water operations via
Runways 15R and 33L; and restrict nighttime engine run-ups and use of auxiliary power
units (APUs). 
▪ Massport continues to encourage the voluntary use of reduced-engine taxiing when
appropriate and safe (see Appendix L, Reduced/Single Engine Taxiing at Logan Airport
Memoranda ). 
▪ Massport continues improvement of the Noise Monitoring System. Massport went out to
bid in 2018 and selected the prior vendor in 2019. Upgrades to the system and some
noise monitors have begun. 
▪ Sound Insulation Program 
▪ Massport has one of the most extensive residential and school sound insulation programs
in the nation. To date, Massport has installed sound insulation in 5,467 residences,
including 11,515 dwelling units, and 36 schools in East Boston, Roxbury, Dorchester,
Winthrop, Revere, Chelsea, and South Boston. Since the start of the program, over $170
million has been invested. 
▪ Approximately 8 percent of applicants also choose the Room-of-Preference option that
allows the owner to identify a room (usually a bedroom or living room) for extra
acoustical treatment.

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-23 
Air Quality/Emissions Reduction 
Total emissions from all sources associated with Logan Airport are less than they were a decade ago, with
the exception of NO x . This long-term downward trend is consistent with Massport’s longstanding 
objective to accommodate the demands of increasing passenger and cargo activity levels with fewer
aircraft operations and reduced emissions wherever possible. When compared to 2017, the changes in air
emissions in 2018 and 2019 remain within expected values given the corresponding upturn in aircraft
operations. Due to the COVID-19 pandemic, there are far fewer aircraft operations, passengers, and
overall activity at Logan Airport. Reductions in aircraft operations and ground access trips will likely result
in reduced emissions in 2020. 
Massport prepared emissions inventories for 2018 and 2019 for the criteria pollutants carbon monoxide
(CO), particulate matter (PM 10 /PM 2.5 ), and volatile organic compounds (VOCs), as well greenhouse gases
(GHGs) and oxides of nitrogen (NO x ). Key findings of those emissions inventories include: 
▪ Total modeled emissions of CO, PM 10 /PM 2.5 and NO X , increased from 2017 to 2018 by approximately
14 percent, 17 percent, and 4 percent, respectively. VOCs remained consistent. These increases were
mainly attributable to the 5.6-percent increase in aircraft operations in 2018 compared to 2017.
Variations in emissions were also due to airframe/engine combination parameters included in the two
model versions used and the associated differences in applied emission factors assumed in the
models. 
▪ In 2019, total modeled emissions of CO, PM 10 /PM 2.5 , and VOCs each increased by about 2 percent
from 2018. NO X emissions instead increased by about 5 percent. These changes are also due to an
increase in aircraft operations of 0.7 percent as well as slight variations in the aircraft fleet mix from
2018 to 2019. Additionally, increases in NO X emissions in 2019 are associated with higher stationary
source fuel usages in that year. 
▪ Modeled emissions of CO, VOC, and NO X associated with GSE and motor vehicles, many of which
Massport has influence, have declined from 2018 to 2019. Emissions of PM 10 /PM 2.5 remain steady.
While there are model version differences between 2017 and 2018, causing variances in emissions
between those years, overall GSE and motor vehicles show a decreasing trend from 2017 to 2019 for
all pollutants. 
▪ Total Logan Airport GHG emissions increased from 2017 to 2018 by approximately 10 percent and
from 2018 to 2019 by approximately 4 percent. These increases are primarily due to the increase in
aircraft operations (i.e., 5.6 percent in 2018 and 0.7 percent in 2019). GHG emissions associated with
Logan Airport in 2018 and 2019 are approximately 1 percent of the most recent statewide emissions
estimates.

Boston Logan International Airport 2018/2019 EDR 
Introduction/Executive Summary 1-24 
Effect of Aircraft Engine Technology on NO x 
Aircraft emissions continue to represent the largest source (95 percent) of NO x at Logan Airport, followed
by other sources (2 percent), ground service equipment (GSE) (2 percent), and motor vehicles (1 percent).
Massport does not have any control over aircraft emissions, which represent the vast majority of total
airport emissions. 
To reduce fuel use and emissions, aircraft engine designers and manufacturers continue to work on 
producing more “fuel - efficient” (i.e., less fuel -burning) engines. This is achieved by enhancing engine
performance with improved fuel combustion technologies, greater thrust-generating power, and less
engine wear. Aircraft are also being designed to decrease fuel-burn with advancements in aircraft wing
and body aerodynamics, light-weight alloy materials, and improved means of navigation. These emerging
technologies and reduced fuel burn are expected to reduce emissions, reduce noise, and moderate the
growth in NO x emissions into the future.

Introduction/Executive Summary 1-25 
Air Quality Strategy 
Massport’s air quality management strategy for Logan Airport focuses on decreasing emissions from
Airport-related sources. Since Massport does not have direct control over aircraft operations or fleet
choices of the airlines, it continues to focus on areas that Massport does control or has an opportunity to
influence. Massport ’s air quality management strategy for Logan Airport focuses on decreasing emissions 
from Airport-related sources, in addition to furthering innovative means to achieve emissions reductions
Airport-wide. Massport has established a number of goals and objectives to address air emissions from
Airport operations, including the reduction of GSE and Massport vehicle fleet emissions. Massport is
focused on the following initiatives: 
▪ Provide infrastructure and encourage practices that support reductions in aircraft emissions 
▪ Massport provides pre-conditioned air (PCA) and 400 Hertz (Hz) power at all aircraft contact
gates to reduce aircraft idling and use of APUs. 
▪ Massport encourages single engine taxiing procedures by the airlines when safe, to reduce
both noise and air emissions. 
▪ Use of battery powered tugs and belt loaders for the Delta Air Lines ground service fleet at
Terminal A. Massport is advancing plans to extend the infrastructure for plug-in GSE to other
locations. 
▪ Maximize use of HOV and reduce single occupancy vehicle trips, particularly drop-off/pick-up
trips, and passenger use of private vehicles to and from the Airport 
▪ Massport implements an extensive HOV strategy and ground transportation improvements
(see following section, Ground Access Strategy, for details). 
▪ Reduce emissions from fleets operating at Logan Airport 
▪ Massport is facilitating the replacement of gas- and diesel-powered GSE with all-electric GSE
(eGSE) by the end of 2027 (as commercially available). In 2018, EPA awarded a grant to
Massport to replace gas- and diesel-powered GSE at Logan Airport. This grant will be used in
conjunction with an FAA VALE grant Massport received in the fall of 2018 to install eGSE
charging stations as part of the Terminal B Optimization Project. In 2019, through the same 
program, Massport was awarded funds for jetBlue Airways’ charging infrastructure at Terminal 
C, Massport contributed toward the installation of 42 eGSE charging stations. 
▪ In 2019, Massport was awarded a grant through the Massachusetts Department of 
Environmental Protection’s (MassDEP’s) Volkswagen Diesel Settlements & Environmental 
Mitigation Open Solicitation grant program, aimed at reducing NO X and GHG emissions, to
acquire eGSE in partnership with jetBlue. This will replace 31 pieces of GSE with new eGSE and
install four eGSE charging stations at Terminal C. United Airlines also privately pursued this
grant and was awarded funding. 
▪ Additionally, in 2019 EPA awarded Massport a DERA grant to replace 44 diesel-powered GSE
equipment with all-electric baggage tractors, belt loaders, and push back tugs. GSE owners at
Logan Airport will contribute a match.

Introduction/Executive Summary 1-26 
▪ Provide infrastructure to support alternative fuels including compressed natural gas (CNG) and
electricity 
▪ Massport continues to operate one of New England’s largest retail CNG stations, which is
open to the public. In 2018 and 2019, the CNG station pumped approximately 25,750 and
24,445 gasoline-gallon equivalents per month for all Massport fleet vehicles
(non-Massport vehicles were also using CNG). 
▪ Massport supports the current and future standard systems for plug-in electric vehicles

vehicles in the Central Garage and Terminal B parking areas. Massport has increased the
availability of EV charging stations so that 150 percent of this demand is available at all
facilities at all times and will continue to evaluate demand as passenger activity levels
return. Currently, there are 123 charging ports installed at Logan Airport and more at the
Logan Express sites. 
▪ Reduce emissions from Massport fleet vehicles 
▪ Massport continues to run and augment its fleet of 54 alternative fuel vehicle
(AFV)/alternative power vehicle (APV) on-Airport shuttle buses. Massport also has a
vehicle procurement policy that requires consideration of AFVs when purchases are
made. 
▪ Reduce emissions associated with Massport buildings, including energy needs 
▪ Massport has committed to achieving Leadership in Energy and Environmental Design
(LEED®) certification for eligible buildings, as appropriate. 
▪ Massport continues to invest in renewable energy installations on-Airport (solar/wind). 
Environmental Compliance and Management/Water Quality 
Massport ’s approach to environmental management and compliance is a key component of its
commitment to sustainability and responsible stewardship at Logan Airport. Through monitoring and
documentation, Massport assesses environmental performance, continually developing, implementing,
evaluating, and improving policies and programs. Massport promotes appropriate environmental
practices through pollution prevention and remediation measures. Massport also works closely with
tenants and operations staff at Logan Airport in an effort to continuously improve environmental
compliance. Key findings in this EDR include: 
▪ In 2018, approximately 97 percent of Massport’s stormwater samples were in compliance with 
National Pollutant Discharge Elimination System (NPDES) permit requirements and in 2019,
approximately 99 percent of samples were in compliance. 
▪ Massport has had its International Organization for Standardization (ISO) 14001 Environmental
Management System (EMS) in place since 2006. 
▪ Massport annually updates and maintains its Stormwater Pollution Prevention Plan (SWPPP) for
Logan Airport.

Sustainability and Resiliency Program 
Massport is committed to a robust sustainability program. Sustainability has redefined the values and
criteria for measuring organizational success by using a "triple bottom line" approach that considers
economic, ecological, and social well-being. Applying this approach to decision-making is a practical way
to optimize economic, environmental, and social capital. Massport is taking a broad view of sustainability
that builds upon the triple bottom line concept and considers the airport-specific context. Consistent with
the Airports Council International - North America’s (ACI -NA) definition of Airport Sustainability, 24 
Massport is focused on a holistic approach to managing Logan Airport to ensure Economic viability,
Operational efficiency, Natural resource conservation, and Social responsibility (EONS). Massport is
committed to implementing environmentally sustainable practices Airport- and Authority-wide and
continues to make progress on a range of initiatives. The following sections summarize many of the
long-term and multifaceted sustainability initiatives undertaken by Massport, which individual chapters of

Logan Airport Sustainability Management Plan (SMP) 
In 2013, Massport was awarded a grant by FAA to prepare a SMP for Logan Airport. The Logan Airport
SMP planning effort began in May 2013 and was completed in April 2015. The Logan Airport SMP takes a
broad view of sustainability including economic vitality, operational efficiency, natural resource
conservation, and social responsibility considerations. The Logan Airport SMP is intended to promote and
integrate sustainability Airport-wide and to coordinate ongoing sustainability efforts across Massport. The
Logan Airport SMP developed a framework and implementation plan, with metrics and targets, designed
to track progress over time. 
Massport is currently working on a vision for Massport’s “Sustainability 2.0” as a next -level planning effort
to implement principles and approaches from the SMP at other Massport facilities and to update 
Massport’s sustainability goals and targets. Massport is currently advancing a series of short -term
initiatives to help reach its goals (see Table 1-1 ) in the areas of (1) energy and GHG emissions; (2) water
conservation; (3) community, employee, and passenger well-being; (4) materials, waste management, and
recycling; (5) resiliency; (6) noise abatement; (7) air quality improvement; (8) ground access and
connectivity; (9) water quality/stormwater; and (10) natural resources. Massport reports its progress
towards achieving each goal, including changes in related performance, in sustainability reports. Since the
publication of the Logan Airport SMP, Massport has continued expanding its sustainability initiatives, with
an increased focus on implementing resliency measures to protect Maritime and Logan Airport
operations, cirital infrastructure, and workforce. 
The Logan Airport Annual Sustainability Report , first published in April 2016, provides a progress summary 
of sustainability efforts at Logan Airport based on Massport’s sustainability goals and targets established 
in the Logan Airport SMP. It highlights Mass port’s progress towards improving sustainability and 
enhancing resiliency at its facilities. This report, now called the Annual Sustainability and Resiliency Report ,

Introduction/Executive Summary 1-32 
Climate Change and Resiliency Planning 
As the Boston area will continue to experience increased temperatures, more frequent extreme weather
events, and higher sea level due to climate change, 25 Massport understands the importance of preparing
for impacts to protect and enhance its critical infrastructure, operational assets, and workforce. Through
robust planning and regional collaboration, Massport strives to continue its leadership role in resiliency
planning among port authorities, the airport industry, and the Boston region. 
At the end of 2013, Massport initiated a Disaster and Infrastructure Resiliency Planning (DIRP) Study for
Logan Airport, the Port of Boston, and Massport’s waterfront assets in South and East Boston. The DIRP 
Study includes a hazard analysis, modeling sea-level rise and storm surge, and projections of temperature,
precipitation, and anticipated increases in extreme weather events. The DIRP Study provides
recommendations regarding short- term strategies to make Massport’s facilities more resilient to the likely 
effects of climate change. In 2014, the study was completed, and implementation of adaptation initiatives
began, in late 2014. 
In addition to the DIRP Study and its related initiatives, Massport has completed an Authority-wide risk
assessment, as part of its strategic planning initiative; issued a Floodproofing Design Guide ; and has
developed a resilience framework to provide consistent metrics for short- and long-term planning and
protection of its critical facilities and infrastructure. Beyond infrastructure resiliency, Massport is also
focused on incorporating social and economic resilience into its long-term operational and capital 
planning. Massport’s Floodproofing Design Guide was published in November 2014 and updated in
November 2018. 
Operational aspects of resiliency strategy include the development of Flood Operations Plans for
Logan Airport and Massport maritime facilities. These plans were introduced in 2014 and included the
planned deployment of temporary flood barriers to protect up to 12 locations of critical infrastructure in 
25 City of Boston. 2016. Climate Ready Boston .

Massport Partnerships and Community Support 
Massport has a long-standing commitment to be a good neighbor. Working in concert with government,
community, and civic leaders throughout Massachusetts and New England, Massport is an active 
participant in efforts that improve the quality of life for residents living near Massport’s facilities . Massport
employees participated in a number of community activities in 2018 and 2019. In the spring, Massport
employees participated in the City of Bos ton’s annual neighborhood Boston Shines clean-up. At
Thanksgiving, Massport employees provided food donations to three community programs, which served
more than 500 families and individuals each month. In the fall, children ages four to 17 were provided
with a new backpack filled with school supplies and new clothes at the start of the school year. Over the
holidays, Massport invited students from neighboring communities and elementary schools to sing at
Terminal A as part of its annual holiday music program. 
Open Space/Buffer Program 
Massport has invested in an extensive open space program to enhance the surrounding communities.
Massport initially committed over $15 million for the planning, construction, and maintenance of four
Airport edge buffer areas and two parks along Logan Airport’s perimeter. These buffers include the
Bayswater Embankment Airport Edge Buffer, Navy Fuel Pier Buffer, and the Southwest Service Area
(SWSA) Buffer (Phases I and II). The award-winning Piers Park was completed in 1995 and has since
become part of a network of greenspace that traverses East Boston from the Jeffries Point waterfront to
Constitution Beach. 
Adjacent to the current Piers Park, Piers Park Phase II will add approximately 4.2 acres of green space to
the East Boston waterfront upon completion, and plans are underway by an outside party for Piers Park
Phase III, which will turn an aging pier into a 3.6-acre greenspace that will include resiliency features to
help protect the neighborhood from flooding and sea level rise. Today, East Boston enjoys 3.3 miles and
more than 33 acres of green space developed or managed by Massport, in partnership with and in
response to engagement with the East Boston community. More information can be found in Chapter 3, 
Airport Planning .

Introducción/Resumen Ejecutivo 
(Spanish Executive Summary)

EDR del 2018/2019 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-1

Introducción/Resumen ejecutivo 
Introducción 
Massachusetts Port Authority (Massport) continúa con su práctica de casi cuatro décadas de brindar un registro
exhaustivo sobre las tendencias medioambientales, el planeamiento de las instalaciones, y los niveles de
operaciones y de pasajeros del Aeropuerto Internacional Logan de Boston (Aeropuerto Logan o Aeropuerto) y
los compromisos de mitigación de Massport en este Informe de datos medioambientales (Environmental Data
Report, EDR) de 2018/2019. Como Massport ha hecho periódicamente después de la circulación y revisión de
nuestros Informes de Estado y Planificación Ambiental (Environmental Status and Planning Reports, ESPR), con la
aprobación del secretario de la Oficina Ejecutiva de Energía y Asuntos Ambientales (Executive Office of Energy
and Environmental Affairs, EEA) de Massachusetts, este EDR de 2018/2019 combina datos y análisis para los años
naturales 2018 y 2019. 
Este EDR fue preparado en el 2020 durante la pandemia de la COVID-19 en curso. Massport se ha esforzado por
incluir actualizaciones relevantes hasta el otoño del 2020 inclusive, cuando las condiciones actuales dieron lugar
a cambios en los proyectos o programas que estaban vigentes en el 2018 y 2019. A partir de marzo del 2020, los
vuelos de entrada y salida del Aeropuerto Logan se redujeron drásticamente y los niveles de pasajeros
disminuyeron en más del 90 por ciento en el pico de la pandemia en la primavera y el verano del 2020. Por lo
tanto, actualmente hay muchas menos operaciones de aviones y pasajeros, y se produjo una caída dramática en
la actividad general del Aeropuerto Logan. Si bien los niveles de actividad comenzaron a recuperarse lentamente
a mediados del verano del 2020, la actual oleada de casos de COVID-19 ha dado lugar a niveles de actividad
históricamente bajos y se prevé una recuperación total en los próximos años. En octubre del 2020, el total de
operaciones de vuelo del año se redujo aproximadamente en un 50 por ciento y los niveles de pasajeros se
redujeron en un 70 por ciento en comparación con los de enero a octubre del 2019. Massport prevé que, para
finales del 2020, los niveles de pasajeros habrán bajado a niveles de actividad no observados desde mediados de
la década de 1970. 
Las disminuciones del tráfico aéreo causada s por las recesiones económicas y otras “perturbaciones”, como los 
acontecimientos del 11 de septiembre del 2001 y la Gran Recesión del 2008/2009, han sido seguidas por ciclos
de recuperación gradual. Como se muestra en la Figura 1-1 , después de los acontecimientos del 11 de
septiembre del 2001 y la recesión posterior, los niveles de actividad de los pasajeros del Aeropuerto Logan
disminuyeron en alrededor del 18 por ciento, pero se recuperaron cinco años después. Los volúmenes de
pasajeros del Aeropuerto Logan disminuyeron en alrededor de un 9 % después de la Gran Recesión del
2008/2009. Como se muestra en la Figura 1-2 , en 2020 el promedio de siete días del caudal de detección de
pasajeros la Administración de Seguridad en el Transporte (Transportation Security Administration, TSA) se
redujo en más del 90 por ciento muy rápidamente. En la Figura 1-3, se muestra el cambio porcentual en el
caudal mensual de la TSA desde el 2019 al 2020 para la nación y para Boston.

EDR del 2018/2019 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-2 
La COVID-19 está afectando de una manera sin precedentes no solo la industria de la aviación sino la economía
mundial. Mientras que la preocupación inmediata y más apremiante es el costo humano, la COVID-19 ha creado
profundas implicaciones para casi todos los negocios e industrias. El impacto en la aviación ha sido
particularmente grave. La situación cambia a diario y sigue habiendo una incertidumbre considerable en cuanto a
la duración de esta pandemia y sus repercusiones a largo plazo.

Notas: Terminal de aeropuerto Logan (izquierda) y reclamo de equipaje (derecha) durante la pandemia de COVID-19. 
Como resultado de esta significativa reducción en la actividad del Aeropuerto y la dramática reducción de los
ingresos, tanto Massport como nuestras aerolíneas y otros locatarios han tenido que ajustar y reducir sus
operaciones. Al mismo tiempo, el cronograma de varios proyectos y programas del Aeropuerto han sido
revisados y retrasados. Para brindar la mayor transparencia posible, en el Capítulo 3, Planeación aeroportuaria, se
incluyen las actualizaciones más recientes del proyecto hasta octubre del 2020. Los próximos EDR continuarán
brindando actualizaciones, según estén disponibles. En general, Massport sigue evaluando y planificando la
recuperación de las operaciones de las aeronaves y la actividad de los pasajeros aéreos, y sigue comprometida
con la aplicación de la amplia gama de estrategias ambientales y operativas destinadas a reducir los impactos
asociados a las operaciones del Aeropuerto.

El Aeropuerto Logan, cuyo propietario y operador es Massport, cumple una función clave en las redes de
transporte de pasajeros y de carga en el área metropolitana de Boston y de Nueva Inglaterra. Es el principal
aeropuerto del área metropolitana de Boston, el aeropuerto más importante de Nueva Inglaterra en cuanto a los
servicios de larga distancia y una gran puerta de entrada internacional a los EE. UU. para los servicios
transatlánticos. Los límites del Aeropuerto abarcan aproximadamente 970 hectáreas en el East Boston y
Winthrop, incluidas aproximadamente 283 hectáreas en el puerto de Boston. El Aeropuerto Logan comprende
seis pistas, aproximadamente 24 140 metros de pistas para carreteo y aproximadamente 97 hectáreas de
plataformas de cemento y asfalto. El Aeropuerto Logan tiene cuatro terminales de pasajeros interconectadas
(Terminales A, B, C y E), cada una con sus propias instalaciones de emisión de pasajes, reclamo de equipaje y
transporte terrestre. El Aeropuerto está a menos de cinco kilómetros del centro de Boston y se puede acceder a
este por líneas de transporte público, numerosas líneas de autobuses directas y un sistema de carreteras bien
conectadas. Massport también brinda el servicio de autobuses Logan Express desde y hacia el Aeropuerto Logan
para los pasajeros de vuelos y para los empleados de una serie de aparcamientos de incentivo. 
Este EDR del 2018/2019 pertenece a una serie de documentos de revisión medioambiental anual entregados al
secretario de la EEA, en cumplimiento con la Ley de Políticas Ambientales de Massachusetts (Massachusetts
Environmental Policy Act, MEPA). 1 Desde 1979, Massport presenta estos documentos para informar los efectos
medioambientales acumulados de las operaciones y de las actividades del Aeropuerto Logan. El Aeropuerto

EDR del 2018/2019 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-5 
Logan es el primer aeropuerto del país para el que se confeccionó una evaluación medioambiental anual sobre
las actividades aeroportuarias y Massport continúa siendo líder en informes medioambientales. 
Aproximadamente cada cinco años, Massport confecciona un ESPR, que brinda un panorama histórico y
prospectivo del Aeropuerto Logan. Los EDR, que se confeccionan anualmente en los intervalos entre los ESPR,
brindan una revisión histórica de las condiciones medioambientales para el año que se informa en comparación
con el año anterior. Este EDR del 2018/2019 sigue al ESPR del 2017 que informó las condiciones del 2017, e
incluyó proyecciones y análisis de las futuras operaciones y condiciones medioambientales en función de la
predicción de pasajeros anterior a la COVID-19. Mientras Massport y toda la industria de la aviación continúan
ajustándose a las nuevas condiciones operativas, nosotros seguimos evaluando los impactos actuales y futuros
de la pandemia. Cuando es posible, este EDR incluye información relevante y actualizaciones. Sin embargo, será
necesario realizar proyecciones y análisis más detallados en las próximas ESPRs. 
El alcance de este EDR del 2018/2019 conjunto se estableció mediante la certificación del secretario en el ESPR
del 2017 con fecha del 25 de noviembre del 2019, la que se incluye en el Apéndice A, Certificados y respuestas a
los comentarios de la MEPA. Este EDR cumple todos los requisitos establecidos en la certificación del secretario
en el ESPR del 2017 e incluye respuestas a los comentarios en la certificación del secretario, y actualiza y compara
los datos presentados en el ESPR del 2017 sobre los siguientes temas: 
Para mejorar la utilidad de este EDR como documento de referencia para los revisores, este informe también
presenta datos históricos sobre las condiciones medioambientales en el Aeropuerto Logan desde 1990, en las
instancias en que hay información histórica disponible. Cuando corresponde y está disponible, este EDR también
incluye actualizaciones hasta el otoño del 2020 inclusive. 
Este EDR incluye una traducción al español de este capítulo. Esta versión traducida se incluye después de la
versión en inglés del resumen ejecutivo.

Proceso de revisión medioambiental del Aeropuerto Logan 
Este EDR del 2018/2019 es la próxima presentación de Massport en su proceso de revisión medioambiental
estatal formal, único, pero bien consolidado, que evalúa los impactos medioambientales acumulados del
Aeropuerto Logan. Los documentos brindan un contexto actual e histórico frente al cual los proyectos
individuales del Aeropuerto Logan que alcanzan umbrales de revisión medioambiental estatales y federales se
evalúan sobre las bases de proyectos específicos. A continuación, se describen los procesos de revisión
medioambiental específicos del proyecto para todo el Aeropuerto. 
Contexto histórico para el proceso de EDR/ESPR del Aeropuerto Logan 
En 1979, el secretario de la EEA emitió un certificado solicitando a Massport que defina, evalúe y divulgue cada
tres años el impacto del crecimiento a largo plazo del Aeropuerto a través de un Informe de impactos
medioambientales genérico (Generic Environmental Impact Report, GEIR). En el certificado también se solicitaron
actualizaciones anuales provisorias para brindar datos sobre las condiciones para los años entre los GEIR. El GEIR
evolucionó hasta transformarse en una herramienta de planificación eficaz para Massport y brindó proyecciones
de condiciones medioambientales para que los efectos acumulados de los proyectos individuales se puedan
evaluar dentro de un contexto más amplio. 
La EEA eliminó los GEIR después de las revisiones de 1998 para sus reglamentaciones de la MEPA. Sin embargo,
la certificación del secretario sobre la actualización anual de 1997 2 propuso un proceso de análisis
medioambiental revisado para el Aeropuerto Logan lo que dio como resultado la confección de los EDR/ESPR de
Massport subsiguientes. El ESPR más amplio brinda un análisis de largo alcance de las operaciones, de los
pasajeros y de los impactos acumulados proyectados, mientras que los EDR se confeccionan anualmente para
brindar una revisión de las condiciones medioambientales para el año que se informa en comparación con el año
anterior. Se desarrolló el proceso del EDR/ESPR para permitir que se analicen los proyectos individuales en el
Aeropuerto Logan en un contexto más amplio en todo el Aeropuerto. Como se estableció en la introducción del 
ESPR de 1999, “mientras que el ESPR y el EDR de Logan br indan el contexto amplio de la planificación para los
proyectos propuestos para el Aeropuerto Logan y los conceptos de planificación futuros que Massport analiza, 
2 Certificación del secretario de la Oficina Ejecutiva de Asuntos Medioambientales sobre la actualización anual del Aeropuerto Logan de
1997, emitida el 16 de octubre de 1998.

EDR del 2018/2019 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-7 
no se puede crear ningún proyecto solamente en las bases de inclusión y análisis en el ESPR de 1999” . Luego,
establece que los proyectos que cumplen con los umbrales de revisión de la MEPA o Ley Nacional de Políticas
Ambientales (National Environmental Policy Act, NEPA) deben someterse a estos procesos, si es necesario. En
resumen, los EDR/ESPR brindan un contexto de planificación acumulada que complementa las presentaciones
individuales específicas del proyecto. 
En el 2018 y 2019, si bien los niveles de pasajeros tuvieron un crecimiento significativo y alcanzaron nuevos
niveles máximos, las operaciones de las aeronaves y los efectos medioambientales asociados se mantuvieron
bien por debajo de los niveles analizados previamente para el Aeropuerto Logan. Por lo tanto, el crecimiento de
la aviación pronosticado presentado en el ESPR del 2004, la afirmación sobre la que se estableció inicialmente el
cronograma del ESPR, no se produjo. En consecuencia, con la aprobación del secretario, Massport confeccionó
los EDR del 2009 y del 2010 en lugar del ESPR originalmente planeado para el 2009. El ESPR del 2011, presentado
a principios del 2013, informó sobre el año natural del 2011 y los pronósticos de los niveles actualizados de las
actividades de los pasajeros y de las operaciones de las aeronaves. El EDR del 2012/2013 conjunto presentó
condiciones para ambos años naturales, 2012 y 2013. En el EDR del 2014, el EDR del 2015 y el EDR del 2016 se
presentaron las condiciones para los años naturales del 2014, 2015 y 2016, respectivamente. Del mismo modo,
con el fuerte crecimiento de pasajeros y la evolución de las tendencias de acceso terrestre con la industria
emergente de las aplicaciones de transporte en coche (previamente conocido como empresas de red de
transporte o transportation network company, TNC), la EEA permitió a Massport aplazar el ESPR del 2016 . 
El ESPR del 2017 proporcionó un análisis integral acumulado de los niveles de actividad y de las condiciones
medioambientales para el 2017 y un horizonte de planeación futura. En el ESPR, Massport propuso confeccionar
un EDR del 2018/2019 conjunto para informar los efectos de todas las actividades del Aeropuerto Logan basadas
en la actividad de pasajeros y en las operaciones de las aeronaves reales en el 2018 y 2019. Este documento
responde a la aprobación de la EEA del EDR del 2018/2019 conjunto. 
Si bien este informe se centra principalmente en los años 2018 y 2019, Massport ha incluido la mejor información
disponible sobre el año 2020, a medida que la Autoridad y la nación reaccionan ante la pandemia de la COVID-
19. Si corresponde, Massport continuará identificando y abordando cualquier tendencia de aviación y
medioambiental a largo plazo tanto en los EDR como en los ESPR.

Introducción/Resumen ejecutivo 1-8 
Revisión específica del proyecto 
Aunque esta revisión de todo el Aeropuerto brinda el contexto de planificación más amplio para los proyectos
propuestos y para los conceptos de planificación futuros, determinados proyectos del Aeropuerto también están
sujetos al proceso público de revisión medioambiental específico del proyecto cuando cumplen los umbrales de
revisión medioambiental estatal. Cuando se requiere, Massport y los locatarios del Aeropuerto presentan
formularios de notificación ambiental (Environmental Notification Forms, ENF) e informes de impacto ambiental
(Environmental Impact Reports, EIR) de conformidad con la MEPA. De manera similar, cuando se desencadena la
revisión medioambiental de la NEPA, se revisan los proyectos de acuerdo con el proceso de revisión
medioambiental de la NEPA. 3 Los proyectos actuales y futuros potenciales que se prevé que se sometan a la
revisión de conformidad con la MEPA y/o NEPA se analizan en el Capítulo 3, Planeación aeroportuaria . 
Contexto de la planificación del Aeropuerto Logan 
El Aeropuerto Logan cumple una función clave en las redes de transporte de pasajeros y de mercadería del área
metropolitana de Boston y de Nueva Inglaterra. El Aeropuerto es uno de los aeropuertos con terreno más
limitado del país y está rodeado en tres laterales por el puerto de Boston (consulte las Figuras 1-4 y 1-5 ).

En el 2019, los niveles de actividad de pasajeros aéreos en el Aeropuerto Logan alcanzaron 42,5 millones
en todo momento, un aumento del 3,9 por ciento en comparación con el 2018 (40,9 millones). Como ha
sido la tendencia reciente antes de marzo del 2020, las operaciones de las aeronaves aumentaron a un
ritmo más lento que las de los pasajeros. En el 2019, las operaciones llegaron a un total de 427 176 y en el
2018 las operaciones llegaron a un total de 424 024. Estos dos niveles representan aumentos en
comparación con los niveles de pasajeros de 38,4 millones y las 401 371 operaciones del 2017
( Figura 1-6 ). El crecimiento observado durante el 2018 y 2019 estuvo directamente correlacionado con las
fuertes economías nacionales y regionales. Incluso con este crecimiento fuerte, las operaciones de las
aeronaves permanecieron muy por debajo de las 487 996 operaciones del 2000 y del pico histórico de
507 449 operaciones alcanzadas en 1998. El crecimiento más lento de las operaciones de las aeronaves en
comparación con los niveles de pasajeros se debe al aumento constante en el tamaño de las aeronaves y
a la mejora en los factores de carga de las aeronaves (pasajeros/disponibilidad de asientos).

Debido a la COVID-19, los niveles de pasajeros y las operaciones del 2020 disminuyeron drásticamente. Hasta
octubre del 2020, interanualmente los niveles de pasajeros y las operaciones han disminuido
aproximadamente un 70 y un 50 por ciento, respectivamente.

Introducción/Resumen ejecutivo 1-12 
Los niveles de actividad del Aeropuerto Logan están estrechamente
ligados a la economía regional y nacional 
Los niveles de actividad del Aeropuerto Logan son impulsados ampliamente por las economías locales,
regionales y nacionales. Tal como puede verse al observar las tendencias a largo plazo, está claro que
cuando la economía es fuerte, el Aeropuerto Logan crece. Análogamente, las disminuciones más
importantes en los niveles de pasajeros y en el funcionamiento de las aeronaves se observan muy cerca
de perturbaciones nacionales e internacionales importantes. Ejemplos de las disminuciones más
significativas incluyen la huelga de la Organización de Controladores Profesionales de Tráfico Aéreo
(Professional Air Traffic Controllers Organization, PATCO) en 1981, el 11 de septiembre del 2001, la Gran
Recesión en el 2008/2009 y ahora la pandemia de la COVID-19. 
Cuando ha habido un crecimiento significativo, como se observó hasta el 2018 y el 2019, Massport ha
puesto en práctica estrategias para abordar ese crecimiento de manera que permita que el Aeropuerto
Logan evolucione de manera sostenible y ambientalmente responsable. 
El Aeropuerto Logan es el aeropuerto más grande de los seis estados de la región de Nueva Inglaterra,
que tiene una población de aproximadamente 14,8 millones de residentes. El Aeropuerto está ubicado en
Massachusetts, que alberga a 6,9 millones de residentes o cerca del 46 por ciento de la población de
Nueva Inglaterra. El Aeropuerto Logan presta servicios a pasajeros de toda Nueva Inglaterra y la principal
zona de influencia está compuesta por los siguientes cinco condados de Massachusetts: Essex, Middlesex,
Norfolk, Plymouth y Suffolk (que incluye la ciudad de Boston). De acuerdo con las estadísticas disponibles
más recientes, 4,4 millones de personas residen en esta área de cinco condados y, según las proyecciones,
la población dentro del área de influencia aumentará un 0,5 por ciento por año en los próximos 19 años. 4 
En el 2019, de manera similar a años anteriores, el área metropolitana de Boston mantuvo una menor tasa
de desempleo (2,6 por ciento) que la de la Mancomunidad (2,9 por ciento) y que la del país entero
(3,7 por ciento). 5 El Aeropuerto no solo atiende a una población en crecimiento, sino también a una
población con mayores ingresos. El ingreso per capita en el 2019 fue de USD 68 361 (dólares
estadounidenses en el 2012) en el área de servicios principal del Aeropuerto, 3,6 por ciento más alta que
en la Mancomunidad y 35,9 por ciento más alta que el promedio nacional. 6 
El Aeropuerto Logan es un recurso de transporte y económico clave en la región de Nueva Inglaterra, en
el estado y en el área metropolitana de Boston, que alberga una gran variedad de industrias. Las
industrias con la mayor cantidad de empleados incluyen la atención médica y la asistencia social, los
servicios educativos, profesionales, científicos y tecnológicos (que incluyen la próspera industria
biotecnológica de Boston). 7 En el 2018 y 2019, Boston se ubicó en el puesto n.° 1 de ciudades de los

EE. UU. en educación y 2.° en atención médica. 8 La contribución de la innovación y la creación de
empresas también es evidente en las últimas estimaciones de crecimiento económico del 2019. 
Además de respaldar el crecimiento y éxito económico del estado, el Aeropuerto Logan y la industria
aeroportuaria son elementos importantes para la economía estatal y regional. La Actualización del estudio
del impacto económico del aeropuerto estatal de Massachusetts, realizada por el Departamento de
Transporte de Massachusetts (Massachusetts Department of Transportation, MassDOT) en el 2014 y
actualizada más recientemente en 2019, 9 calcula que los aeropuertos de Massport (incluidos el
Aeropuerto Logan, Worcester Regional Airport y Hanscom Field) contribuyen con aproximadamente
USD 23,1 mil millones en producción a la economía de Massachusetts anualmente. De esta producción, el
71 por ciento se debe solo al Aeropuerto Logan. 10 La producción total incluye negocios dentro del
aeropuerto, construcción, visitantes y efectos multiplicadores (consulte la Figura 1-7 ). 11 El Aeropuerto
Logan respalda más de 162 000 puestos de trabajo directos e indirectos, al mismo tiempo que genera
aproximadamente USD 16,3 mil millones por año en producción económica total. 12 En el 2019, se
contrataron más de 23 000 personas en el Aeropuerto Logan. Esto incluyó a, aproximadamente, 820
miembros del personal y empleados administrativos adicionales de Massport del aeropuerto Logan. 13

El Aeropuerto Logan se considera un aeropuerto de origen y destino (O&D) 14 tanto nacional como
internacionalmente, lo que significa que, aproximadamente, el 90 por ciento de los pasajeros del
Aeropuerto Logan inician o finalizan su viaje en el Aeropuerto Logan. Los aeropuertos principales, como el
de Atlanta o Chicago, prestan servicios a muchos más pasajeros anualmente, pero en comparación con
los aeropuertos de O&D, como el Aeropuerto Logan, pasa un porcentaje mayor de pasajeros en tránsito
en los aeropuertos principales a través de los vuelos de conexión. Durante el 2019, el Aeropuerto Logan
fue uno de los aeropuertos grandes con crecimiento más rápido de los Estados Unidos en cuanto a la 
14 El “tráfico de origen y de destino” se refiere al tráfico de los pasajeros que se origina o que termina en un aeropuerto o en un 
mercado en particular. Un mercado de O&D fuerte, como Boston, genera una demanda local de pasajeros significativa, ya que
muchos pasajeros inician y terminan su viaje en ese mercado. El tráfico de O&D es diferente al tráfico de conexión, que es
tráfico de pasajeros que no inician ni terminan en el aeropuerto, sino que solo hacen conexiones en el aeropuerto en ruta hacia
otros destinos.

cantidad de pasajeros. 15 Del 2017 al 2019, el tráfico de pasajeros aéreos en los EE. UU. creció un 9,1 por
ciento, mientras que el Aeropuerto Logan experimentó un crecimiento de pasajeros del 10,7 por ciento. 16 
El Aeropuerto Logan se considera un aeropuerto de origen y destino (O&D) nacional e internacional, lo
que significa que, menos de 10 por ciento de los pasajeros aéreos están conectando por el aeropuerto
Logan. 
Estado de las predicciones 
En el ESPR del 2017 , se presentó una predicción actualizada para las operaciones de las aeronaves y la
actividad de los pasajeros del Aeropuerto. La predicción se centró en un horizonte de planeación futura
que incluyó una proyección de 50 millones de pasajeros aéreos anuales y 486 000 operaciones de
aeronaves anuales. Las proyecciones del ESPR de Massport fueron congruentes con la proyección del área
de la terminal de la Administración Federal de Aviación (FAA) en ese momento. Sin embargo, la pandemia
de la COVID-19 redujo drásticamente el tráfico de pasajeros aéreos y, actualmente, se prevé que tomará
unos cuantos años hasta que la industria vuelva a los niveles de operaciones previos a la COVID-19. 
Durante el 2018 y el 2019, debido a la economía sólida, los niveles de actividad de los pasajeros y de las
operaciones de aeronaves en el Aeropuerto Logan aumentaron rápidamente. Esta tendencia de
crecimiento finalizó en marzo del 2020 y, en consecuencia, las proyecciones del ESPR del 2017 tendrán
que ajustarse a medida que se comprendan mejor los efectos a más largo plazo de la pandemia de la
COVID-19. 
Inversiones de Massport en el Aeropuerto Logan 
Massport evalúa e implementa mejoras en el Aeropuerto Logan, en la seguridad, en la eficacia operativa y
en el acceso desde y hacia el área metropolitana de Boston, mientras controla atentamente los efectos
medioambientales de las operaciones del Aeropuerto Logan. Un enfoque continuo ha sido mejorar la
experiencia del pasajero y del usuario en el Aeropuerto Logan. Los proyectos del área de la terminal
recientes y en curso están destinados a brindar una conectividad posterior a la seguridad sin
inconvenientes entre las terminales y mejoras al sistema de proceso de pasajeros a través de las áreas de
verificación de seguridad consolidadas. El acceso al Aeropuerto Logan y sus alrededores continúa siendo
una prioridad. Massport continúa trabajando con la FAA para mejorar la seguridad en la zona de
operaciones a través de una variedad de mejoras en la seguridad del área de las pistas (runway safety
area, RSA) y de simplificaciones en la geometría del campo de aviación 
Como se mencionó anteriormente, los efectos de la pandemia de la COVID-19 han precipitado una gran
serie de cambios en el Aeropuerto Logan. Tanto la disminución de los pasajeros como los ingresos
asociados han requerido importantes ajustes en los servicios y en los cronogramas de los proyectos.
Massport se ha centrado en ajustar los servicios para que se ajusten a los cambiantes niveles de pasajeros 
15 Entre el 2014 y el 2019, el Aeropuerto Logan fue el 20.° aeropuerto con crecimiento más rápido en los EE. UU. en términos de
tráfico local de O&D en comparación con los 30 aeropuertos principales de los EE. UU. (encuesta de O&D del Departamento de
Transporte [Department of Transportation, DOT] de los EE. UU.).

y en asegurar que esos cambios se hagan teniendo muy en cuenta la gestión de los impactos ambientales
y de operación. En algunas áreas, se ajustaron los programas para reflejar las necesidades y los impactos
actuales. Estos ajustes temporarios se describen en los capítulos técnicos correspondientes de este EDR.
Massport sigue comprometida en implementar estrategias de mitigación relacionados a proyectos, como
documentado en Capitulo 9, Medidas que benefician al medioambiente y seguimiento del proyecto de
mitigación . 
Aspectos destacados y hallazgos clave del 2018 y 2019 
Esta sección brinda un breve resumen de los hallazgos clave, por capítulo, en el Aeropuerto Logan en el
2018 y 2019. También se incluye una breve actualización sobre la actividad en el 2020 y las proyecciones
futuras a la luz de la pandemia de la COVID-19. Se ofrece información adicional sobre las actividades del
Aeropuerto en los capítulos subsiguientes. Esta sección también destaca las iniciativas de Massport para
una mayor sustentabilidad a través de proyectos específicos e iniciativas con una hoja de sustentabilidad
y resume el programa de sustentabilidad de Massport. 
El Certificado del Secretario sobre el ESPR del 2017 , que constituye el alcance de este EDR del 2018/2019 ,
reconoció el crecimiento rápido en los últimos años y le ordenó a Massport que proporcionara
actualizaciones sobre la proyección del ESPR del 2017 . Si bien el crecimiento reciente y rápido de
pasajeros del Aeropuerto Logan continuó hasta principios del 2020, la pandemia de la COVID-19
comenzó a reducir drásticamente las operaciones del aeropuerto y los pasajeros a mediados de marzo del
2020. En las fases iniciales de la pandemia, los niveles de pasajeros disminuyeron por más del 90 por
ciento. Si bien los niveles de actividad comenzaron a recuperarse lentamente a mediados del verano del
2020, la actual oleada de casos de COVID-19 ha dado lugar a niveles de actividad históricamente bajos y
la recuperación total se dará en algunos años. En octubre del 2020, el total de operaciones de vuelo del
año se redujo en un 50 por ciento y los niveles de pasajeros se redujeron en un 70 por ciento en
comparación con los de enero a octubre del 2019. Massport prevé que, para finales del 2020, los niveles
de pasajeros habrán bajado a niveles de actividad no observados desde mediados de la década de 1970.
Hasta que no se comprendan mejor los impactos a largo plazo de la COVID-19, Massport solo puede
hacer proyecciones preliminares de la tasa de recuperación de los niveles de pasajeros. El próximo EDR
proporcionará más actualizaciones con la mejor información disponible en ese momento. 
Niveles de actividad 
Hasta el inicio de la pandemia de la COVID-19, el Aeropuerto Logan (y la industria de la aviación en
general) había estado experimentando un fuerte crecimiento, en gran parte por las condiciones
económicas positivas en la región de Boston, el bajo desempleo, una base económica diversa y fuerte, y la
inversión continua en bienes raíces comerciales y residenciales, en ciencias biológicas en particular, en las
finanzas, en la atención médica y en la educación superior. Debido a la pandemia de la COVID-19, los
niveles de pasajeros y las operaciones del 2020 disminuyeron drásticamente. Hasta octubre del 2020,
interanualmente los niveles de pasajeros y las operaciones han disminuido aproximadamente un 70 y un
50 por ciento, respectivamente.

EDR del 2018/2019 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-17 
Los niveles de actividad de pasajeros aéreos en el Aeropuerto Logan en el 2018 y 2019 aumentaron a 40,9
millones en 2018 y 42,5 millones en el 2019. Las operaciones de las aeronaves continuaron la tendencia a
largo plazo de aumentar a un ritmo más lento que los pasajeros. En el 2018, las operaciones llegaron a un
total de 424 024 y en el 2019 las operaciones llegaron a un total de 427 176. Ese crecimiento estuvo
directamente correlacionado con la fuerte economía nacional y regional. Incluso con el fuerte crecimiento,
las operaciones de las aeronaves permanecieron muy por debajo de las 487 996 operaciones del 2000 y
del pico histórico de 507 449 operaciones alcanzadas en 1998. La combinación de un menor número de
operaciones en aeronaves más limpias y silenciosas ha dado lugar a una reducción drástica de los
impactos ambientales en comparación con los valores máximos históricos. 
Del 2010 al 2019, la cantidad anual de pasajeros en el Aeropuerto Logan aumentó alrededor de un 55 por
ciento, mientras que la cantidad anual de operaciones 17 aumentó más lentamente, alrededor del 21 por
ciento, debido al aumento de los factores de carga de las aeronaves. Los niveles de pasajeros
internacionales aumentaron más rápidamente que los niveles de pasajeros con destinos nacionales en el
2018 y 2019. Los niveles de actividad de los pasajeros aéreos con destinos domésticos aumentaron un
6,9 por ciento y un 2,6 por ciento en 2018 y 2019, respectivamente, mientras que los niveles de actividad
de los pasajeros aéreos con destinos internacionales aumentaron un 5,3 por ciento y un 9,7 por ciento,
respectivamente. 
Consulte el Capítulo 2, Niveles de actividad, para obtener información adicional . 
Planeación aeroportuaria 
Massport continuamente mejora las instalaciones del Aeropuerto Logan para adaptarlo a los cambios de
la demanda de pasajeros, de la actividad de las aeronaves, de las necesidades de las cargas y del acceso al
transporte. En el Capítulo 3, Planeación aeroportuaria , Massport ha identificado proyectos de planeación e
iniciativas prioritarios en las siguientes categorías: 
▪ Transporte terrestre y estacionamiento. 
▪ Terminales. 
▪ Planificación de la zona de operaciones. 
▪ Áreas de servicio. 
▪ Amortiguadores del Aeropuerto y espacio abierto 
▪ Energía, sustentabilidad y resiliencia 
Durante el 2018 y 2019 se prestó gran atención a las medidas de reducción del acceso terrestre y de los
viajes, y a las mejoras de las terminales. Los proyectos del área de la terminal recientes y en curso brindan
una conectividad y flexibilidad posterior a la seguridad sin inconvenientes entre las terminales y mejoras
al sistema de proceso de pasajeros a través de las áreas de verificación de seguridad consolidadas.

Para mejorar la red de carreteras en el Aeropuerto, Massport está mejorando varios de los segmentos de
carreteras e intersecciones del área de la terminal. En octubre del 2019, Massport abrió sus nuevas áreas
consolidadas para recoger o dejar pasajeros de las aplicaciones de transporte en coche en Central Garage.
En el 2018 y 2019, Massport también adelantó varios servicios de medios de transporte masivos (HOV) y
realizó mejoras en las instalaciones de Logan Express como parte de sus objetivos de reducción de viajes. 
Desde la presentación del ESPR del 2017 , Massport ha completado la revisión medioambiental estatal y/o
federal de numerosos proyectos: 
▪ El Proyecto de Estacionamiento del Aeropuerto Logan, que añadirá 5000 espacios de estacionamiento
comercial en el Aeropuerto Logan en ubicaciones que ya se usan para el estacionamiento. Los
espacios de estacionamiento adicionales dependen de la aprobación de MassDOT y de la Agencia de
Protección Medioambiental de los EE. UU. (EPA) de una modificación a la reglamentación del
Congelamiento del Estacionamiento en el Aeropuerto Logan. 18 Los espacio adicionales tienen como
objetivo reducir las modalidades para recoger/dejar pasajeros perjudiciales para el medioambiente
(es decir, recoger o dejar pasajeros en vehículos privados, en taxi, aplicaciones de transporte en coche
o mediante servicios de limusinas con chofer). El proceso de revisión conjunto de la MEPA/NEPA se
completó en enero del 2020. Actualmente, este proyecto está aplazado debido a la reducción en la
actividad de los pasajeros asociada con la pandemia de la COVID-19. 
▪ El proyecto de la terminal C de la cubierta, conexiones y carreteras recibió la aprobación
medioambiental federal según la NEPA en noviembre del 2018. Como se describe en el ESPR del 2017 ,
la construcción de este proyecto sustituirá y reconfigurará secciones de las carreteras elevadas que
conectan las Terminales B y C. En este momento, se prevé que el reemplazo de la cubierta comience y
se complete en el 2021, con un programa ligeramente reducido respecto a lo previsto originalmente.
Se prevé que se complete el conector de la Terminal B a la C en la primavera del 2022 y que las
carreteras estén terminadas en el 2023. 
Massport continúa trabajando con la FAA para mejorar la seguridad en la zona de operaciones a través de
una variedad de proyectos en la seguridad del área de las pistas y de simplificaciones en la geometría del
campo de aviación Consulte el Capítulo 3, Planeación aeroportuaria, para obtener más información . 
Transporte regional 
En el 2018 y 2019, se observó un aumento en la actividad de pasajeros aéreos en la región de Nueva
Inglaterra. Los pasajeros aéreos de la región aumentaron en un 6,5 por ciento a 58,3 millones de pasajeros
aéreos en el 2018 y luego otro 2,5 por ciento a 59,7 millones en el 2019. Los 10 aeropuertos regionales
(sin incluir el Aeropuerto Logan) de Nueva Inglaterra prestaron servicios a 17,3 millones y 17,2 millones de
pasajeros aéreos en el 2018 y 2019, respectivamente, en comparación con 16,3 millones de pasajeros en
el 2017. 
Worcester Regional Airport, T.F., Green Airport, Portland International Jetport, Burlington International
Airport y Bangor International Airport experimentaron un aumento general de las operaciones de

Introducción/Resumen ejecutivo 1-19 
servicios comerciales desde el 2017. Los aeropuertos Manchester-Boston Regional, Tweed-New Haven,
Bradley International y Portsmouth International vieron reducida su oferta de servicios desde el 2017. 
Los tres aeropuertos de Massport, el Aeropuerto Logan, Worcester Regional Airport y Hanscom Field
contribuyeron de manera significativa con la economía regional, generando aproximadamente USD 23,1
mil millones anualmente o el 94 por ciento de los beneficios de la economía general generados por el
sistema de aeropuertos de Massachusetts. Hanscom Field es un aeropuerto de relevo del Aeropuerto
Logan y es el segundo aeropuerto con mayor actividad en Nueva Inglaterra. 
En Worcester Regional Airport aumentó la cantidad de pasajeros en un 76 por ciento en el 2019 en
comparación con el 2017, y se informó un total de aproximadamente 817 057 pasajeros desde el 2013
hasta el 2019. En los últimos cinco años, Worcester Regional Airport experimentó una tasa de crecimiento
promedio del 10 por ciento por año. Massport continúa invirtiendo en Worcester Regional Airport. Junto
con la ciudad de Worcester, Massport ya ha comenzado una inversión de USD 100 millones a 10 años
para revitalizar y atraer operaciones comerciales en Worcester Regional Airport. Las inversiones incluyen
un sistema de aterrizaje instrumental CAT III (alrededor de USD 32 millones) que se pagan con subvención
federal y fondos de Massport. Además, jetBlue Airways, American Airlines y Delta Air Lines anunciaron un
nuevo servicio al John F. Kennedy International Airport (JFK) de Nueva York, al Philadelphia International
Airport y al Detroit Metropolitan Wayne County Airport, respectivamente. Desde la fecha de publicación
de este EDR, se ha suspendido servicios comerciales de pasajeros desde Worcester Regional Airport
debido a la baja en la demanda de los pasajeros como consecuencia de la pandemia de la COVID-19. 
Los viajes de todo el sistema de trenes Amtrak aumentó de 31,7 millones de viajes de usuarios en el año
fiscal (fiscal year, FY) 2018 a 32,5 millones de viajes en el FY 2019. En el FY 2018, el corredor noreste
(Northeast Corridor, NEC) transportó más de 12 millones de pasajeros, alrededor de un 1 por ciento más
que el año anterior. En el FY 2019, el NEC transportó más de 12,5 millones de pasajeros en esos servicios,
alrededor de un 3 por ciento más que el año anterior. 
Acceso terrestre 
El Aeropuerto Logan continúa siendo uno de los principales aeropuertos de los Estados Unidos en cuanto
a la modalidad de HOV y de viajes en transporte público. Massport promueve numerosas opciones de
HOV, transporte público y viajes compartidos para mejorar las carreteras dentro del Aeropuerto y las
operaciones en las aceras, para aliviar las limitaciones de estacionamiento y para mejorar el servicio al
cliente. Los hallazgos clave del 2018 y 2019 se resumen en las viñetas a continuación y se pueden
encontrar detalles adicionales en el Capítulo 5, Acceso terrestre desde y hacia el Aeropuerto Logan. 
▪ El promedio de las millas viajadas por vehículos (vehicle miles traveled, VMT) dentro del Aeropuerto
en los días de semana aumentaron alrededor de un 4,5 por ciento, del 2017 al 2018. Entre el 2018 y el
2019, el promedio de las VMT dentro del Aeropuerto en los días de semana aumentó en un 2,2 por
ciento. El cambio en el tráfico diario promedio se puede atribuir principalmente a los aumentos en la
actividad de los pasajeros, a la actividad de recoger/dejar pasajeros, a la carga y a los usos no
relacionados con la aviación del Aeropuerto. Se prevé que la actividad en el Aeropuerto y las VMT
dentro del Aeropuerto serán significativamente menores en el 2020 debido al impacto de la COVID-
19.

EDR del 2018/2019 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-20 
▪ Las transacciones de las aplicaciones de transporte en coche alcanzaron un total de más de 7 millones
en el 2018 y aumentaron a más de 8 millones en el 2019, un crecimiento de más del 16 por ciento. Las
aplicaciones de transporte en coche tienen un impacto en otras modalidades de acceso al Aeropuerto
y contribuyen a la congestión dentro del Aeropuerto. Parcialmente debido al continuo aumento de
las aplicaciones de transporte en coche, los viajes en limusinas con chofer y los viajes programados en
van disminuyeron en, aproximadamente, un 23 por ciento del 2017 al 2019. Los viajes en taxis
disminuyeron un 14 por ciento en el 2018 en comparación con el 2017, y un 7 por ciento entre el
2018 y el 2019. La cantidad de pasajeros de la línea Blue de la Autoridad de Transporte de la Bahía de
Massachusetts (Massachusetts Bay Transportation Authority, MBTA) aumentó en un 4 por ciento entre
el 2017 y el 2018, y disminuyó en un 29 por ciento el año siguiente. 
▪ En función de cambios en las elecciones de la modalidad de los pasajeros para acceder al Aeropuerto
Logan entre el 2017 y el 2019, Massport actualizó sus objetivos y su definición de HOV. La definición
actualizada considera que los taxis, las limusinas con chofer y las aplicaciones de transporte en coche
que llevan a más de un pasajero aéreo por vehículo son HOV, mientras que las mismas modalidades
con un pasajero aéreo no contarán como HOV. Con esta definición actualizada, Massport estableció
un objetivo del 35,5 por ciento de HOV para el 2022 y del 40 por ciento para el 2027. Según los
resultados de la Encuesta de acceso terrestre de pasajeros aéreos del 2019, la modalidad de HOV
compartida alcanzó el 40,4 por ciento, superando tanto los objetivos a corto como a largo plazo. Si
bien se prevé que la modalidad de HOV compartida disminuirá como resultado de la COVID-19 a
corto plazo, Massport prevé que la cantidad de pasajeros en el HOV se recupere con el tiempo y
sigue comprometido con los objetivos de la modalidad de HOV compartida en el futuro. 
Estrategia para el acceso terrestre 
Massport cuenta con una estrategia integral múltiple de reducción de viajes de larga data para diversificar
y mejorar las opciones de transporte terrestre para los pasajeros y para los empleados que viajan desde y
hacia el Aeropuerto Logan. La estrategia está diseñada para ofrecer a los pasajeros la oportunidad de
elegir entre HOV, transporte público y opciones de viajes compartidos que son prácticas y confiables, y
que reducen los impactos medioambientales y en la comunidad. Desde hace muchos años, el Aeropuerto
Logan ocupa el puesto número uno en los aeropuertos de los EE. UU. en términos de HOV y modalidades
de transporte público compartido. Massport promueve numerosas opciones de HOV, transporte público y
viajes compartidos para mejorar las carreteras dentro del Aeropuerto y las operaciones en las aceras, para
aliviar las limitaciones de estacionamiento y para mejorar el servicio al cliente. 
La estrategia de Massport también tiene como objetivo brindar suficiente estacionamiento dentro del
Aeropuerto para los pasajeros aéreos que eligen la modalidad de acceso en automóvil y/o que tienen
opciones de HOV limitadas. En el 2017, MassDEP enmendó el Congelamiento del Estacionamiento en el
Aeropuerto Logan para permitir un aumento de hasta 5000 espacios de estacionamiento comercial
dentro del Aeropuerto, lo que permite la construcción de estacionamientos adicionales para reducir el uso
de las modalidades para recoger/dejar pasajeros, y para aliviar las condiciones de estacionamiento
limitado dentro del Aeropuerto.

EDR del 2018/2019 del Aeropuerto Internacional Logan de Boston 
Introducción/Resumen ejecutivo 1-21 
Un interés de larga data de Massport es abordar la congestión de las carreteras dentro del Aeropuerto
con una combinación de cambios en las políticas y con mejoras en la infraestructura. Es importante aliviar
la congestión de la zona de las terminales para que las operaciones en tierra sigan siendo seguras y
eficientes, y para reducir los impactos ambientales. Mejorar las opciones de transporte multimodal, y
brindar una infraestructura moderna y flexible es una forma mediante la cual un aeropuerto puede reducir
las emisiones de gases de efecto invernadero (greenhouse gas, GHG) y de mejorar su huella ecológica. 
Massport reconoce la importancia de proporcionar servicios de HOV seguros y confiables desde y hacia el
Aeropuerto, y para el 2019 ya había alcanzado su plan estratégico de aumentar la parte de la modalidad
de HOV al 40 por ciento para el 2027. Comprender el crecimiento del uso de las aplicaciones de
transporte en coche y su impacto en la congestión de las carreteras regionales y de las zonas de las
terminales es esencial para gestionar el volumen de tráfico dentro del Aeropuerto y para promover los
servicios de HOV como una alternativa viable y atractiva. Las reducciones de las posibles emisiones son
una razón por la que Massport está comprometido con un objetivo a largo plazo para fomentar y
respaldar el HOV público y privado, y los servicios de viajes compartidos dirigidos a los pasajeros aéreos,
a los usuarios del Aeropuerto y a los empleados. Otros beneficios incluyen los siguientes: 
▪ Reducir la congestión en las carreteras de las terminales y en las aceras de las áreas para
recoger/dejar pasajeros. 
▪ Aliviar las restricciones en las instalaciones de estacionamiento limitadas. 
▪ Servicio al cliente (brindar una variedad de opciones de transporte para las diferentes
características demográficas de los viajeros). 
Aunque este informe se centra principalmente en la actividad en el 2018 y 2019, como consecuencia de la
pandemia de la COVID-19, en el 2020 se modificaron temporalmente varias medidas de reducción del
HOV y de los viajes de Massport. Los vuelos desde y hacia el Aeropuerto Logan se han reducido
drásticamente y los niveles de pasajeros disminuyeron casi un 90 por ciento a partir de marzo del 2020.
Como consecuencia, aunque los niveles operativos y de pasajeros se recuperaron un poco a mediados del
2020, en general, hay muchos menos pasajeros y empleados que viajan hacia y desde el Aeropuerto
Logan y hay mucha menos congestión en las carreteras en el período pico tanto en Boston como en el
área metropolitana. Además, el interés de la comunidad por utilizar los servicios de transporte HOV, como
los autobuses, el tránsito rápido y el ferrocarril suburbano, se ha visto considerablemente afectado por las
preocupaciones de la salud p ú blica relacionadas con la COVID-19. 
En ese contexto, Massport sigue evaluando y planificando la recuperación de la actividad de los pasajeros
aéreos y mantiene su compromiso de implementar la amplia gama de estrategias de acceso terrestre que
se esbozaron en el ESPR del 2017 cuando demanda para estas medidas se recuperen. Sin embargo, el
cronograma de esos servicios y las mejoras previstas se han ajustado debido a las continuas limitaciones
operacionales y a las reducciones de ingresos. Massport continúa revisando cuidadosamente los niveles
de actividad dentro y fuera del Aeropuerto, y ajustará sus programas de acceso terrestre para alinearlos
con los niveles de cantidad de pasajeros. Los próximos EDR brindarán actualizaciones detalladas sobre
todos los ajustes a los servicios y los niveles de actividades. 
Massport evalúa continuamente sus estrategias y programas destinados a mejorar y, donde sea necesario,
expandir los servicios de HOV hacia y desde el Aeropuerto Logan, incluida la continua inversión en las
instalaciones y el servicio de Logan Express. Las iniciativas descritas a continuación pueden mejorar las

operaciones en las carreteras, así como la calidad de las emisiones atmosféricas. Las siguientes medidas
se implementaron o siguen en análisis: 
▪ El objetivo de duplicar la cantidad de pasajeros en Logan Express para cuando el Aeropuerto
Logan alcance 50 millones de pasajeros aéreos al expandir el estacionamiento, la frecuencia y las
mejoras en las instalaciones. 
▪ Mejoras al servicio suburbano de Logan Express 
▪ En 2019, Massport aumentó la capacidad de asientos totales en el Logan Express en más 
de 10 por ciento. 
▪ Aumentar el servicio de Braintree Logan Express de dos a tres viajes por hora
(implementado en mayo del 2019, pero reducido a un servicio por hora en marzo del
2020 debido a los impactos de la COVID-19). 
▪ Agregar unos 1000 espacios más a Framingham Garage (el permiso se completó en el
2020, pero la construcción está aplazada). 
▪ Brindar estado de prioridad en la cola de seguridad para los usuarios de Logan Express
Back Bay (implementado en el 2019; este servicio está actualmente suspendido debido a
la COVID-19). 
▪ Realizar campañas de publicidad para respaldar la estrategia de Logan Express y para
aumentar la cantidad de pasajeros. 
▪ Implementar la emisión de boletos electrónicos para Logan Express (pendiente). 
▪ Evaluar las nuevas ubicaciones suburbanas de Logan Express, con un plan para abrir, al
menos, un sitio nuevo (aplazado debido a la COVID-19). 
▪ Explorar las conexiones de destino final de las aplicaciones de transporte en coche. 19 
▪ Continuar monitoreando la capacidad de estacionamiento en todos los sitios de Logan
Express. 
▪ Línea Silver de la MBTA 
▪ Massport adquirió ocho autobuses de la línea Silver de la MBTA en el 2005 y los opera la 
MBTA, y Massport paga los costos operativos. Dado que la flota existente de la línea
Silver está llegando al final de su vida útil, la MBTA y Massport han estado trabajando
juntos en un plan para conseguir una flota de reemplazo de la línea Silver. Como parte de
esta iniciativa, Massport y la MBTA elaboraron un Estudio de capacidad de la línea Silver
para determinar las necesidades a mediano plazo de la flota y las instalaciones, así como
para evaluar otras formas de mejorar la confiabilidad y la capacidad del sistema En
función de este análisis, la MBTA tiene previsto adquirir 45 nuevos vehículos híbridos
eléctricos mejorados para sustituir la flota actual de 32 vehículos de modo dual. Massport
planea comprar ocho autobuses de la línea Silver de la MBTA como parte de una próxima
adquisición de la MBTA.
