The Iowa Department of Natural Resources reports that 88 counties notified the DNR last month that they plan to evaluate construction permit applications and proposed locations for animal confinements by using the master matrix.
Animal producers in these counties must meet higher standards than other confinement producers who also need a construction permit. They must earn points on the master matrix by choosing a site and using practices that reduce impacts on air, water and the community.
Among the 11 counties not using the matrix are Keokuk and Washington Counties.
