Maryland is suing the U.S. Environmental Protection Agency in an attempt to force federal regulators to crack down on upwind air pollution from five other states. Since 2015, Maryland has required its power plants to use such “scrubbing” systems daily during summer months. State officials want the EPA to impose similar requirements for upwind regions in other states. Maryland asked federal regulators in November to force Indiana, Kentucky, Ohio, Pennsylvania and West Virginia to take steps reduce air pollution. “It gets pretty hard after you attack those two sources of air pollution to find other ways of making the air cleaner and healthier,” Frosh said in an interview.
