Earlier this month the US Environmental Protection Agency (EPA) proposed a new
rule to significantly reduce air pollution from locomotive and marine diesel
engines -- a move supported by many environmentalists and health advocates.
"Cleaning up diesel locomotives and marine engines will save lives," said
Christine Bryant, speaker of the American Lung Association Nationwide Assembly.
"Communities across the nation urgently need these reductions to help clean up
dangerous ozone and particle pollution. The American Lung Association will be
pushing EPA through the public comment process to accelerate the timeline for
The proposed Clean Air Locomotive and Marine Diesel Rule would set stringent
emission standards and require the use of advanced technology to reduce
"By tackling the greatest remaining source of diesel emissions, we're keeping
our nation's clean air progress moving full steam ahead," said EPA
Administrator Stephen L. Johnson. "Over the last century, diesels have been
America's economic workhorse, and through this rule, an economic workhorse also
is becoming an environmental workhorse."
When fully implemented, this initiative would cut particulate matter emissions
from these engines by 90 percent and nitrogen oxides emissions by 80 percent.
This would result in annual health benefits of $12 billion in 2030 and reduce
premature deaths, hospitalizations and respiratory illnesses across the United
States. These benefits would continue to grow as older locomotive and marine
engines are replaced. Overall benefits are estimated to outweigh costs by more
than 20 to 1, officials said.
The locomotive remanufacturing proposal would take effect as soon as certified
systems are available, as early as 2008, but no later than 2010. Standards for
new locomotive and marine diesel engines would phase-in starting in 2009.
Long-term standards would phase-in beginning in 2014 for marine diesel engines
and 2015 for locomotives. The rule also explores a remanufacturing program for
existing large marine diesel engines similar to the existing program for
locomotives. Other provisions seek to reduce unnecessary locomotive idling.
