Grain Processing Corporation (GPC) has agreed to a record $1.5 million fine and ordered to hire an independent firm to conduct a comprehensive environmental audit of its Muscatine corn-processing facility to assure compliance with federal and state environmental laws.
The consent decree approved Thursday (3/27) by a Muscatine County judge resolves a lawsuit filed by the Iowa Attorney General in December 2011, and addresses air and water pollution violations cited by the Iowa Department of Natural Resources (IDNR) as far back as 2009.
The Muscatine firm, owned by Kent Corporation, announced a $100-million capital improvement program for the GPC plant after the lawsuit was filed, and in its news release Thursday promised the plant upgrades will reduce air emissions "well below the newest and more stringent air quality standards now set by the EPA."
The company also said when its new corn-drying facility is complete, "smoke, odor, and haze will be nearly eliminated" at the facility.
Muscatine has been designated as in "non-attainment" for fine particulate (PM 2.5) pollution by the U.S. Environmental Protection Agency (EPA). In 2013, of the 14 exceedances of air quality standards for PM 2.5 statewide, seven were recorded in Muscatine. For the same period, all 67 exceedances of air quality standards for sulfur dioxide (SO2) statewide were recorded in Muscatine.
