New York's Bus Cleanup Brings Other Cities On Board
By RANDY KENNEDY
Two years after the Metropolitan
Transportation Authority and state
lawmakers struck a landmark deal
to clean up what comes out ofthe
tailpipes of the city's 4,500 buses, the
results are beginning to be seen - or
more accurately, not seen -around
the city.
Along Madison Avenue, plied by so
many buses that environmental offi-
cials installed an air monitor there in
the late 1980's to track the high levels
of diesel soot, it is now hard to spot a
city bus trailing even a modest cloud
of black smoke.
The reason can be found at a cav-
ernous bus garage in the Bronx,
where over the last several months
transit mechanics and engineers
have been completely rebuilding the
guts of the city's oldest and most
polluting diesel
buses,
installing
cleaner, custom-made engines and
placing powerful fiiters on the ex-
haust pipes.
The improvements to the buses,
and New York City Transit's deci-
sion in the fall of 2000 to switch to a
special ultra-low-sulfur diesel fuel,
has resulted in a strange situation
for transit officials: environmental-
ists, the same ones whohounded
them relentlessly for years to clean
up bus emissions, are actually happy
with them now, and seem impressed
by the progress the agency has made
toward meeting the goals set in Alba-
ny to improve the city's air.
But more important than that, en-
vironmentalists say, is the ripple ef-
fect that the agency's actions have
had across the country in fights to
make other bus fleets more environ-
mentally friendly.
The authority,
as the 800-pound
gorilla of the nation's mass transit
services, does more than influence
other agencies' decisions, transit of-
ficials and environmentalists say, It
virtually creates its own market for
cleaner vehicles and fuels.
When the authority agreed to use
ultra-low-suifur diesel two years ago,
for exampie, it was not widely avall-
able in mass quantities in the United
States, and the Environmental Pro-
tection Agency would not start re-
quiring production of it until 2006.
New York transit officials, in fact,
thought they might have to import it

from Rotterdam.
But when a bus fleet that buys 42
million gallons of fuel a year - as
the authority does -decides it wants
to start buying ultra-low-sulfur die-
sel, it is a good bet that fuel compa-
nies will start to produce it, and they
amount of soot particles and air-
borne sulfur, a component of ozone
and smog. But it also makes it possi-
ble for the rebuilt New York City
buses to use complex exhaust filters,
which are about the size of a small
keg of beer and are concealed inside
the back engine compartment.
The filters - which reduce parti-
cle emissions even more, making
diesel buses almost as clean in many
respects as natural gas buses
would not work with regular diesel
fuel, because the soot particles creat-
In turn, this made it easier for
other bus fleets around the country
to begin using it. Last fall, for exam-
ple, the District of Columbla's fleet of
1,400 buses switched, estimating that
the change would reduce the amount
of particulate matter - tiny, poten-
tially dangerous soot particles that
can lodge in the lungs - by about 17
*I think the M.T.A.'s commitment
to cleaning up its bus fleet has had
huge repercussions with virtually ev-
ery other large bus fleet in the coun-
try," said Richard Kassel, a senior
lawyer for the Natural Resources
Defense Council, one of the groups
that pushed hardest for the change.

said that the agency has continued,
because the new fuet reduces the
as part of its agreement with the
state, to expand its fleet of natural
gas buses and those known as hybrid
electrics, which use small diesel en-
gines to power electric motors at-
tached to the wheels.
But Mr. Seay added that advances
in cleaning diesel emissions have
come so rapidly, just in the last two
years, that it is not altogether clear
which kind of fuel will emerge as the
best choice for the environment. Nat-
ural gas engines, for instance, stlll
produce some carbon dioxide, a sig-
nificant greenhouse gas, and nitro-
gen oxide, a component ofsmog.
So far, the authorityis operating
221 natural gas buses, and plans to
increase its fleet to 650. There are
only 10 of the hybrid buses onthe
road, in a pilot program, but the
agency says it will have 125 deliv-
ered by the end of thisyear and
expects to have 400 by 2000-

about seven of the city s oldest buses
every week, junking the old engines
and installing new 1,110 pound ones
with electronic emission controls
and pollution filters.
John Walsh, the authority's chief
bus maintenance ofticer, said that
more than 450 of the 572 oldest buses,
some with as many as 15 years on
the road, have been rebuilt, at a cost
of about $85,000 a bus. Newer-buses
undergoing routine maintenance are
also having filters installed, and
work is on schedule to equip every
diesel bus with a filter by the end of
next year,he said, in keepingwith
the agency's agreementwith the
state.
Surveying the work last week at
the Zerega
Avenue garage, Mr.
Waish pointed to a long row of rusty,
dingy-looking engines, the old ones,
