The U.S. Environmental Protection Agency and the Justice Department today announced that Amtrak, the nation's largest passenger rail operator, has signed an agreement to carry out environmental audits at its facilities nationwide and undertake other environmental improvements, including projects to restore wetlands and reduce PCBs in locomotive transformers. The agreement settles claims that Amtrak violated numerous requirements of the Clean Water Act, including its storm water provisions, at nine Amtrak sites in New England.
