SAN FRANCISCO (MarketWatch) – Over the years, exhaust-spewing automobiles have been the primary target of tighter emissions standards. This past week, the federal focus moved to ships and trains, whose smokestacks have long belched black soot unhampered by pollution regulations.
The crackdown came from Friday from the Environmental Protection Agency, which proposed a combination of requirements aimed at slashing particulate emissions from diesel locomotives and ship engines by up to 90% and cutting harmful nitrogen oxide emissions by up to 80% by 2030.
The rules, expected to become final by the end of the year, would affect about 21,000 locomotives, 40,000 vessels, and cost roughly $600 million to implement.
According to the EPA, the plan takes a huge step toward combating respiratory illness, eventually saving the nation $12 billion a year in health-care costs. Major port cities like New York, Long Beach and Houston, where railroad lines gather at dockside shipping terminals, stand to benefit the most in terms of improved air quality.
The proposed clean air locomotive and marine diesel rule is the latest step in the government’s wide-ranging effort to clean up diesel engines, which was expanded in 2004 to include construction and farm equipment. Buses and trucks were the first to bow to tighter exhaust rules back in 2000.
At the behest of the railroads, shipping companies and engine manufacturers, the changes will be phased in gradually.
For the railroads, new locomotives must meet the new rules by 2009. Enforcing the stricter requirements for existing locomotives might drag out until 2010, depending on when the industry can
