New York City Transit and the Environment
Every day, each person who chooses to travel by
bus or train contributes to a cleaner environment. That translates into
approximately 700,000 cars kept out of New York City's central business
district daily. It also means 400 million fewer pounds of soot, carbon
monoxide, hydrocarbons, and other toxic substances released each year
into the city's air. However, we do more at NYC Transit than transporting
seven million people a day. We also develop and implement programs to
improve the environment.
ISO 14001 - Environmental
Management System
An Environmental Management System is a long-range
plan that measures environmental program goals and effectiveness.
ISO 14001 sets international rules and guidelines for an EMS. NYC
Transit’s Department of Capital Program created an EMS certified
to ISO 14001 standards. Check out our blueprint for going green,
here and in our policy.

The Clean Fuel Bus Program
NYC Transit is a leader in the field of alternative fuel sources and new technologies for cleaner buses. We were the first public transit system in the country to switch all diesel buses to ultra-low sulfur fuel. Follow our progress.
ISO 14001 -
Environmental Management System
ISO stands for the International Organization for Standardization,
a worldwide group that defines international environmental management
criteria for the manufacture, provision, and distribution of goods
and services in a series of standards known as ISO 14000.
An EMS is an Environmental Management System, a structured, measurable method
for identifying and measuring an organization’s environmental impact. It provides
a framework for an organization’s environmental programs and goals. ISO 14001
creates an EMS model that the American National Standards Institute has endorsed
as the EMS standard for the United States.

NYC Transit, through the efforts of its Department of Capital Program Management
(CPM), is the first public agency in America and one of the first transit systems
in the world to have an Environmental Management System (EMS) certified to
ISO 14001. (Click here to see the certificate). In
short, we created a comprehensive long-term plan to ensure our projects conform
to international standards for environmental sustainability.
EMS Benefits include:
- Improved and enhanced environmental performance
- Pollution prevention and resource conservation
- Increased efficiency and cost reduction
- Employee awareness of environmental issues and responsibilities

Sustainable Development
Sustainable development supports the concept that economic and social
development is complementary to environmental protection. It involves
long-and-short-term planning
to increase community and business growth and productivity without
diminishing the health and productivity of supporting and surrounding
natural systems.
NYC Transit’s Department of Capital Program Management (CPM) is responsible
for design and construction management of roughly two billion dollars
of capital construction projects a year. NYC Transit uses significant
amounts of electrical power, fuel, water, and construction materials.
However, NYC Transit maintains
a commitment to sustainability, and continues to meet the needs of
the present without compromising the ability of future generations
to meet their needs.
NYC Transit, through its Department of Capital Program Management (CPM),
has implemented many programs that promote sustainability. In December
2003, NYC Transit was the first public transportation organization
in North America and one of the first in the world to become a Full
Signatory member of the International
Association of Public Transport (L' Union Internationale
des Transports Publics, or UITP)
Charter on Sustainable Development.
In 2000, NYC Transits Department of Buses launched the Clean
Fuel Bus Program to improve air quality. In June 2001, former
New York State Governor George E. Pataki issued Executive Order (EO)
111, Green and Clean State Buildings and Vehicles. This directive sets goals
for green building designs, energy-efficient State buildings, energy
from renewable sources, and the procurement of energy-efficient products,
and alternative fuel vehicles. All MTA agencies are working in compliance
with EO 111 and continuing sustainable development efforts.

Green
Building Program
NYC Transit Capital Program Management's Environmental
Management System (EMS) incorporates Resource
Efficiency/ Sustainability so that
all construction projects - from building design to subway expansion
-consider these criteria to increase energy efficiency; enhance indoor
environmental quality; conserve water and natural resources; and make
beneficial use of waste, e.g., recycling programs:
- Review projects’ specifications to replace conventional materials
with environmentally “friendlier” resources.
- Evaluate energy efficient
alternative products
- Consider products with a high-salvage value.
- Procure local products
to minimize transportation energy.
- Use paints, sealants, and caulking
that have low VOCs (volatile organic compounds) and minimal off-gas*
potential. Low-VOC building materials do not release significant
pollutants. *Off-gas refers to VOC emissions into the environment.
Recycled
Content in Construction Materials
The Roosevelt Avenue Subway Station project used fly ash to replace
up to 15 percent of the cement in the concrete mix. Not only didn’t
the fly ash become waste product but we also added the unused cement
to another project. Specifications for all capital construction projects
now include coal combustion fly ash in thick concrete mix to save cement.

This colorful cement mixer has a 15
percent blend of fly ash in place
of concrete. The unused concrete became part of another building project.
Construction Waste
NYC Transit has diverted thousands of tons of traditionally landfill-bound
construction waste for recycling. NYC Transit’s Stillwell Avenue Terminal,
Brooklyn, and Roosevelt Avenue, Queens, Subway Station rehabilitation
projects recycled up to 85 percent of construction debris, including
concrete, metal, glass and paper.
Waste Management and Subway Cars

“Redbird” subway cars begin a new life
underwater as artificial reefs
for marine life.
NYC Transit made more than 1,200 “retired “Red Bird” subway cars available
to Virginia, Georgia, South Carolina, Delaware and New Jersey. The
cars had served subway customers for many years. Now they had a new
purpose-- to help form artificial reefs and become habitats for marine
life. After we stripped the subway cars of components that float (oils,
solids, etc.) and decompose, NYC Transit steam cleaned the cars, which
were loaded on barges and “buried” at sea.
Air Pollution Prevention
Volatile Organic Compounds (VOC) Abatement Systems
Volatile Organic Compounds, (VOC) are pollutants that certain
substances emit when they mix with the air we breathe. When NYC Transit
installed a bus paint booth at the Grand Avenue Bus Maintenance facility
in Queens, we used a green design with a carbon bed to absorb VOC released
in air exhaust. A new regenerative thermal oxidizer also controls air
pollutant emissions. The new bus painting system in the Grand Avenue
facility reduces environmental pollutants as much as 95 percent in
comparison with conventional paint spray booths. Now, all of our new
paint booths employ the best available control technology.
Automatic Fluid Application
We are retrofitting paint fluid applications at nine bus depots
to reduce the volume of wasted paint in the bus painting process.
Reducing paint volume not only saves paint but also means that we need
to remove fewer Volatile Organic Compounds (VOC) pollutants from air
exhausts.
Low-NOx Boilers
NYC Transit is replacing old boilers with Low-NOx (Nitrogen
Oxides) boilers. Conventional boilers produce NOx emissions that contribute
to smog. The Low-NOx boilers reduce Nitrogen Oxides emissions by 70
to 85 percent compared to older boiler equipment. In some instances,
we are retrofitting older boilers to burn fuel more efficiently and
using a higher-grade of heating oil.
Photovoltaic (PV) Panels
Sunlight produces illumination and electricity. In the mid-nineties,
NYC Transit began installing solar power units with photovoltaic (PV)
panels.
The 300kW system on the roof of the Gun Hill Road Bus Depot in the
Bronx is one of the largest PV facilities on the East Coast.
The New Corona Car Washer and Maintenance Facility, Queens, has a 100kW rooftop
system.
The 60,000-square-foot photovoltaic canopy over the Stillwell Avenue Subway Terminal
(Coney Island-Stillwell Avenue Station, Brooklyn) produces 250kW of clean power.

Stillwell Avenue-Coney Island, Brooklyn
is the first subway station
to use solar energy.
The Roosevelt Avenue-74th Street Station, Queens, produces 65 kW using
two PV systems: the roof has a conventional system; the second system,
mounted to the metal standing seam canopy of the elevated platform,
is composed of thin-film solar panels.

Hydrogen Fuel Cell
A fuel cell is an electrochemical energy device that generates electricity
for powering motors, lights, buildings, etc. Fuel cells convert hydrogen
and oxygen into electricity and heat. This creates power more efficiently,
and with less pollution. One of the renewable energy sources at the
New Corona Car Washer and Maintenance Facility in Queens is a 200 kW
Fuel Cell unit installed with support from the New York Power
Authority. The Corona Maintenance Facility is expected to exceed the
New York State code for energy efficiency by 36 percent, and is the
first NYC Transit facility certified under the Leadership in Energy
and Environmental Design Standard, LEED, ™ created by the US Green
Building Council.

This fuel cell (background) converts hydrogen
and oxygen into electricity
and heat to save energy.

The US Green Building Council (www.USGBC.com) created LEED®.
NYC Transit’s
Corona Maintenance Facility in Queens is LEED® certified.
Natural Lighting/Day Lighting
The Corona Maintenance Facility in Queens uses natural lighting to
complement or replace electric lighting. The day lighting enters the
building through side windows and skylights. Special “Low-e” (low energy)
coatings on window glazing allow the transmission of visible portions
of solar energy into the building interior while blocking infrared
and ultraviolet components of light that would otherwise introduce
heat.

Maintenance Facility
In July 2004, New York City's Department of Environmental Protection (NYC
DEP), in cooperation with the United States Environmental Protection Agency
(USEPA), announced the winners of its first Green Buildings Design Competition
to demonstrate ways to integrate green building ideas in new and existing New
York City structures. The Roosevelt Avenue -74th Street Station received an
award for excellence in the use of good design principles and the integration
of green building technologies. The New Corona Car Washer and Maintenance
Facility received honorable mention for excellence in integrating sustainable
design strategies into a railcar maintenance facility.

Energy/Electricity
Conservation
Heat Recovery Units
Ventilation systems use a great deal of energy and are
costly because they require bringing air from outside a building
and adjusting its temperature to maintain an indoor environment. NYC
Transit uses Heat Recovery Units (HRU) in many projects to reduce
a building’s ventilation energy load. When it is cold outside,
an HRU recovers heat from outgoing air by using a heat-exchanger
to preheat fresh incoming air, which the HRU system distributes
throughout the building.

A Heat Recovery Unit (HRU), background, at
the New Corona
Maintenance Facility
Natural Ventilation
Buildings that have natural ventilation do not need as much
mechanical air circulation; this lowers energy consumption, resulting
in a healthier and greener environment. NYC Transit believes that
the best approach to new building ventilation is a mixed mode of
natural and mechanical ventilation, where both systems work independently
or simultaneously, depending on the climate and season, among other
conditions. The New Corona Maintenance Facility (Queens), which
has a mixed mode system, does not require mechanical ventilation
during the summer until the temperature outside reaches the mid-eighties.
ENERGY STAR
ENERGY STAR is an international standard for energy efficient electrical
equipment created by the United States Environmental Protection
Agency (EPA) in 1992. The European Union, as well as Japan, Australia,
Canada, and other countries have adopted it. Most electrical
equipment that NYC Transit currently purchases is ENERGY STAR rated.

Light Emitting Diode Signals
NYC Transit has been replacing its incandescent train signaling
lights with highly efficient light emitting diode (LED) Signals.
Using LED signals means a 60 percent savings in energy compared
with traditional incandescent light. LED lights improve brightness
150 percent, and they decrease greenhouse gas emissions substantially
since the LED signals lower electrical demand and production.
LEDs also have an extremely long life, which reduces landfill
use and saves labor.To date we’ve replaced 47,000 of our 60,000
signal lights with LED.
Fluorescent Lighting
We are replacing incandescent
light bulbs with fluorescent bulbs in subway stations throughout
the system. When NYC Transit switched to T12 fluorescent bulbs,
station lighting increased 750 percent and power consumption decreased
28 percent. An additional change to T8 bulbs kept lighting as bright
as before, but reduced our energy use by an extra 26 percent.
Compact fluorescent bulbs replaced conventional
incandescent light in tunnels because the compact bulb design fit
the same sockets. Compact bulbs offer the same benefits as longer
fluorescent light tubes and have increased tunnel lighting 500
percent with just a modest power increase of 11 percent. What’s
more, since each compact fluorescent bulb consumes four-to-six
times less energy than an incandescent bulb, the compact bulb yields
1,300 fewer pounds of carbon dioxide emissions over its lifetime
of 7,500 to 10,000 hours. Overall, station and tunnel lighting
upgrades have made stations and tunnels brighter, safer, more secure,
and more comfortable, and save NYC Transit $4.8 million a year.

Compact fluorescent bulbs in this tunnel will last 7,500
to 10,000 hours. Formerly, incandescent tunnel bulbs
burned for only 750 hours.
Systems Power Reduction
NYC Transit began surveying depots, yards and other facilities
in the 1990s in collaboration with the New York Power Authority
to reduce power in our heating, ventilation and air-conditioning
systems. NYC Transit completed more than 45 projects between 1993
and 2007 and now saves close to 50 megawatt hours of electricity
annually – that’s upwards of 30 tons of CO2 emissions avoided every
year.
Subway Car Shunting Elimination Program
In 1996, NYC Transit began the Subway Car Shunting Elimination
Program, one of its most successful energy conservation projects.
By modulating the acceleration rate and limiting the top speed
of the 5,800-car subway fleet, NYC Transit reduces energy use per
subway car mile by 12 percent and saves 240 million-kilowatt hours
of electricity annually.
Regenerative Braking
The fleet of New Technologies subway cars (also called New Millennium
Trains) has regenerative braking. Braking action feeds energy back
into the Third Rail that would otherwise be lost as heat when the
train stops. These R-142, R-142A, R-143, and R-160 subway car-models
run on the , ,
,
,
and
routes.

This New Millennium train has brakes that save energy
by feeding it back into the Third Rail when the train stops.
Aluminum Rail
Since aluminum
is a better conductor of electricity than steel, NYC Transit
is experimenting with two kinds of aluminum third rails to save
energy: an all-aluminum rail with a stainless steel cap on its
contact surface; and a steel-and-aluminum hybrid rail that has a
steel base and aluminum cladding on its sides. Aluminum is also
lighter than steel, which means aluminum-component rails are easier
to handle, install, and replace than conventional steel rails.
Water Conservation
Storm Water Management Program
MTA
New York City Transit created a Storm Water Management Program
(SWMP) in accordance with United States Environmental Protection
Agency requirements for storm water regulations under the Federal
Clean Water Act. The program establishes procedures to reduce
pollutants caused by storm water runoff at NYC Transit facilities.
Pollution control measures include construction-site runoff controls,
spill response and prevention, and waste management. Click here
for more information: www.mta.nyc.ny.us/nyct/storminfo/storminfo.htm
Rainwater Collection and “Grey Water” Re-Use
NYC Transit’s Storm Water Management Program
minimizes the use of potable water by harvesting rainwater, and then
recycling it as “grey water” (non-industrial wastewater generated
from domestic processes such as washing dishes, laundry and bathing).
A rainwater collection system on the roof of the New Corona Car Washer
and Maintenance Facility in Queens drains rainwater into a 40,000-gallon
underground storage tank that supplies water to a subway car washer.
See
how the Corona car washer works by clicking here.

This washing system at the Grand
Avenue Bus Depot and Maintenance
Facility in Maspeth, Brooklyn, has
a 200,000-gallon tank.
The Clean Fuel Bus Program
NYC Transit was the first public agency in the world to have a bus
fleet 100 percent accessible to customers who use wheelchairs. NYC
Transit also explored ways to make its bus fleet better for customers
by introducing environmentally friendly features.
In the 1990’s New York City Transit launched an alternative fuel vehicle program.
Former Governor George Pataki and the State Legislature announced a historic
plan on June 1, 2000 to transform the NYC Transit bus fleet into the cleanest
in the world. To date NYC Transit has committed roughly $1 billion to the Clean
Fuel Bus Program with the following results:
-
In September 2000, NYC Transit became the first public transportation
system in the country to switch all diesel buses in the fleet to
ultra-low sulfur fuel, which has 90 percent less sulfur than traditional
fuel and reduces emissions. This was years ahead of federal mandates.
-
To date we have repowered 671 buses, replacing original two-stoke
engines with new, four-stoke engines that are up to 94 percent
cleaner burning. In addition, NYC Transit retired its last 2-stroke
diesel engines in the summer of 2005.
-
NYC Transit has retrofitted more than 3,200 buses with diesel
particulate filters, an emissions control technology that reduces
diesel particulate emissions from engines by as much as 95 percent.
In addition, we have received 1,300 new buses that have diesel
particulate filters.
-
NYC Transit has the largest hybrid-electric bus fleet in North
America. By the end of 2008, the hybrid fleet will reach nearly
700 buses.
