Iowa amends GPC lawsuit over pollution controls

DES MOINES, Iowa (AP) -- Iowa has amended a lawsuit filed against Grain Processing Corp. in Muscatine with additional allegations the company failed to obtain certain air permits or and didn't report all air pollutants.

Attorney General Tom Miller said Thursday that a trial begins in September on the lawsuit originally filed in December 2011.

The Iowa Department of Natural Resources seeks civil penalties for the alleged violations and an order to force them to stop.

The original lawsuit claims GPC emitted excessive particulates and sulfur dioxide, failed to maintain and repair emissions equipment, and failed to comply with notification and emission reduction requirements.

Company spokeswoman Janet Sichterman says the company looks forward to addressing the issues raised in the lawsuit that relate to permits issued over the last 25 to 30 years.
