In January, 89 of 99 Iowa counties notified the DNR that they plan to evaluate construction permit applications and proposed locations for animal confinements by using the master matrix.
With 10 exceptions, all counties will use the matrix during the next 12 months. The following counties will not use the matrix in 2018: Davis, Des Moines, Keokuk, Lee, Mahaska, Osceola, Plymouth, Wapello, Warren and Washington.
Animal producers in these counties must meet more requirements than other confinement producers who need a construction permit. Producers qualify by choosing a site and using practices that reduce impacts on air, water and the community.
