DES MOINES, IOWA (AP) -- Tighter air pollution rules could force millions of dollars worth of improvements at Iowa plants.
Jim McGraw of the Iowa Department of Natural Resources says a review by the Environmental Protection Agency shows pollution limits for some chemicals are too lenient to protect people from lung problems and other illnesses.
The EPA on June 3 announced a rule tightening limits on sulfur-dioxide emissions.
It listed Muscatine County as the only place in Iowa likely to violate the new rule.
That eventually could lead the state to order changes at major emitters such as Grain Processing Corp. and Muscatine Power and Water.
The EPA is revisiting limits on ozone and other small-particle pollution, which could affect other parts of the state.
