The Environmental Protection Agency said Friday that marine and locomotive engines must meet tougher pollution controls, hoping for dramatic cuts in the amount of smog-causing chemicals and soot coming from trains, cargo ships, tugboats and passenger ferries.
A study by Environmental Defense two years ago found that ships at three of the nation's largest ports — Los Angeles, Houston and New York-New Jersey — together produced as much smog causing chemicals as 1 million cars. The group also found the nation's locomotives produced fine soot, or particulate, equal to 70 coal burning power plants and as much smog causing nitrogen oxide as 120 coal plants. (AP)
