WASHINGTON (AP) - The Environmental Protection Agency is proposing to reduce diesel exhaust from trains and ships, a move supported by some environmentalists.
EPA Administrator Stephen Johnson on Friday issued proposed emission standards for diesel locomotive engines, tugs, barges, ferries and recreational marine engines. The toxic chemicals and soot in diesel exhaust contribute to smog and can cause cancer.
``By tackling the greatest remaining source of diesel emissions, we're keeping our nation's clean air progress moving full steam ahead,'' Johnson said in a statement.
The standards, when adopted and fully phased in, would reduce particulate pollution from these engines by 90 percent and smog-forming nitrogen oxides by 80 percent, the EPA said....
Health benefits are estimated at $12 billion by 2030, including 1,500 fewer premature deaths, 1,100 fewer hospitalizations and 170,000 more work days by people breathing easier...
``Cleaning these engines up will prevent death and disease,'' said Frank O'Donnell, president of Clean Air Watch advocacy group.
State and local air pollution officials also welcomed the announcement.
``Every major metropolitan area in the country will benefit from the huge emissions reductions expected from this long-awaited rule,'' said Bill Becker, executive director of the National Association of Clean Air Agencies.
``We estimate the emissions benefits will be equivalent to taking three-quarters of a million diesel trucks off the road each year. EPA deserves a 'thumbs-up' for this proposal,'' he said.
