DNR’s draft rules propose changes in livestock manure storage in northeast Iowa
October 20th, 2022 by Ric Hanson
(Radio Iowa) – Staff in the Iowa Department of Natural Resources have drafted tougher rules for manure storage at any new livestock confinements or cattle feedlots in parts of northeast Iowa. The regulations would apply in areas where the bedrock is closer to the surface and it can be porous. Under current rules for these areas, manure from livestock operations must be stored in concrete structures. If the changes are adopted, the distance from the concrete bottom of any NEW manure pit and the bedrock would have to triple from at least five feet to 15 feet.
Attorney Eldon McAfee represents the Iowa Pork Producers and the Iowa Cattlemen’s Association. He says the changes could end expansion of livestock operations in northeast Iowa. “We could have producers who can’t build livestock operations with concrete manure storage on their farms,” McAfee says, “and that is very important to that area.” More than a dozen environmental groups say the proposed changes don’t go far enough. Michael Schmidt is a staff attorney with the Iowa Environmental Council.
“We are calling on DNR to do a better job regulating all of this manure to reduce the nitrogen, phosphorus and bacteria that enters our drinking water sources, our groundwater, our lakes, rivers and streams,” he says. It will be a few months before any proposed rules — whatever they may be — could be presented to the legislative committee that approves or blocks all state regulations.
The D-N-R is accepting informal comments on the proposed changes until late Friday afternoon. After that, there’s a formal public comment period and a possible rewrite of the proposed rules. The Iowa Environmental Protection Commission has to vote on any changes. Finally, a committee in the legislature that reviews all state regulations will either approve or block any proposed changes.
