MUSCATINE, Iowa (AP) — A judge has certified a class of thousands of Muscatine residents in a lawsuit alleging pollution from a manufacturing plant was a nuisance that damaged their properties.

District Judge Thomas Reidel ruled Wednesday the class will consist of residents who lived within 1.5 miles of the Grain Processing Plant between 2007 and 2012, including 2,000 households and 4,000 or more individuals.

Reidel says the class will be split into two groups that include those who live closest to the plant and those who live farther away.

Residents filed suit in 2012 alleging GPC failed to control emissions from the wet milling plant, spewing harmful pollutants and odors onto their land. They're seeking damages for the lost use and enjoyment of their properties.
