SACRAMENTO, Calif. — The California Air Resources Board is asking the U.S. Environmental Protection Agency toughen nationwide emission rules on locomotives, ones that go beyond the current Tier 4 standard.
Diesel & Gas Turbine Worldwide reports that the California board, under the umbrella of California’s own Environmental Protection Agency, wants locomotives operated in the state to have zero or near-zero emissions. The board's chairman, Mary D. Nichols, says that new standards are needed to protect and clean up the air in “high-risk” communities, specifically ones close to rail yards.
“Reducing locomotive-related emissions and the resulting air toxic hot spots near rail yards is a high priority for disadvantaged communities within California and around the nation,” Nichols says. “A new generation of locomotives will also, once in operation, offer fuel savings to the railroad industry."
