(Radio Iowa) – The Iowa D-N-R heard public comment Tuesday on a new manure management plan for a large cattle feedlot in Clayton County near the headwaters of Bloody Run Creek trout stream. Supreme Beef’s first plan was reversed by a Polk County judge, and Michael Schmidt with the Iowa Environmental Council questioned the details of the new plan. He says Supreme Beef has given no basis for a manure nutrient concentration figure that he says “are inconsistent and untrustworthy numbers.”

Iowa chapters of the Sierra Club and Trout Unlimited successfully challenged the initial manure management plan in court arguing the state agency used “illogical interpretations and applications” in its approval.
