Last month 89 of Iowa’s 99 counties notified DNR that they plan to use the master matrix to evaluate construction permit applications and proposed locations for animal confinements during 2018 and January of 2019. Supervisors in Davis, Des Moines, Keokuk, Lee, Mahaska, Osceola, Plymouth, Wapello, Warren and Washington counties did not pass a construction evaluation resolution, so they will not be using the master matrix this year.
