Confinement Producers Who Need a Permit also Need the Matrix in 86 Counties


By Karen Grimes, DNR

Animal confinement producers who plan to build, expand or increase the animal loading to a confinement facility may be subject to the master matrix in 86 Iowa counties.

These counties formally adopted a resolution that allows the county boards of supervisors to use the master matrix and evaluate proposed locations of animal confinements that are required to apply for construction permits.

Generally, confinements that need a construction permit include confinements of any size that plan to use earthen or unformed manure storage and all operations that will have an animal unit capacity of 1,000 animal units or more after building or modifying a concrete or steel tank, or a confinement building.

However, not all permitted operations need to use the matrix. The matrix is not required for a confinement that was built prior to April 1, 2002, and after construction, expansion or modification the animal unit capacity will be 1,666 animal units or less. Also, the matrix is not required in the 13 counties that haven't adopted a construction evaluation resolution.

Before producers in participating counties can be approved for construction, they must earn points on the master matrix for choosing sites and using practices that reduce adverse impacts on the environment and the community.

Producers who need to apply for a construction permit and are subject to the master matrix must obtain a minimum overall score of 440 and minimum scores of 53.38 in the air subcategory, 67.75 in the water subcategory and a score of 101.13 in the community impacts subcategory.

The county will evaluate the master matrix and make a recommendation to the DNR to approve or disapprove the application. Counties with a valid resolution can also send staff members to accompany the DNR during site surveys and have the right to appeal the permits to the Environmental Protection Commission.

Producers can find more information and a copy of the master matrix on the DNR Web site at http://www.iowadnr.com/afo/matrix.html.

The complete list of counties that have adopted a resolution follows:

Adair, Adams, Allamakee, Appanoose, Audubon, Benton, Black Hawk, Boone, Bremer, Buchanan, Buena Vista, Butler, Calhoun, Carroll, Cass, Cedar, Cerro Gordo, Chickasaw, Cherokee, Clarke, Clay, Clinton, Crawford, Dallas, Davis, Delaware, Des Moines, Dickinson, Dubuque, Emmet, Fayette, Floyd, Franklin, Greene, Grundy, Guthrie, Hamilton, Hancock, Hardin, Harrison, Henry, Howard, Humboldt, Ida, Jackson, Jasper, Jefferson, Johnson, Jones, Keokuk, Kossuth, Linn, Louisa, Lucas, Lyon, Madison, Marion, Mills, Mitchell, Monona, Monroe, Montgomery, Muscatine, O'Brien, Osceola, Page, Palo Alto, Pocahontas, Polk, Pottawattamie, Poweshiek, Ringgold, Sac, Scott, Sioux, Story, Tama, Taylor, Union, Van Buren, Wayne, Webster, Winnebago, Winneshiek, Worth and Wright.

Counties which have passed a construction evaluation resolution

The DNR approved 74 construction permit applications for confinement feeding operations in 2004. Of those, 40 permit applicants were required to use the master matrix. Either the remaining applicants were in a county where the matrix was not required or they did not need the matrix because the operations were first built prior to April 1, 2002, and their animal unit capacity did not exceed 1,666 animal units.

For participating counties, the resolution is in effect from Feb. 1, 2005, through Jan. 31, 2006.
