The EPA is being sued over pollution claims.

ALBUQUERQUE — The U.S. Environmental Protection Agency is being sued by an environmental group that claims the agency has failed to safeguard public health in the West by not limiting the transmission of air pollution across state lines.
The EPA requires states to have plans aimed at addressing the interstate transport of ozone pollution, the primary component of smog, and fine particles or soot, but WildEarth Guardians claims New Mexico, California and a handful of other Western states do not have such plans.
"EPA is two years late in fulfilling its mandatory duty to prepare federal good neighbor plans protecting the public from interstate soot and smog," according to the lawsuit filed Friday in federal court in San Francisco.
