July 26, 2017, Des Moines, IA – As one of 12 legislators who drafted the bill in 2002 that created the Master Matrix, a current member of the Floyd County Board of Supervisors tasked with reviewing Master Matrix applications, and a lifelong Iowa farmer, I have a unique perspective on the Master Matrix, its failings and how it could be improved.

I support the recent petition presented by the Iowa Citizens for Community Improvement and Food & Water Watch because it is needed to restore balance to a system that has failed to adequately protect the rights of all Iowans, and certain precious natural resources unique to different counties, such as Karst topography in northeast Iowa.

The Master Matrix is a scoring system that awards points for livestock producers who adopt additional practices greater than the minimum required by state law.

Points are awarded for increasing the minimum separated distances between concentrated animal feeding operations (CAFOs) and churches, residences, public-use areas, and bodies of water. More restrictive manure management practices score additional points. The Master Matrix has a total of 44 questions that could result in a perfect score of 880 points, but only 440 points are required to get a passing grade.

The Department of Natural Resources’ analysis of the Master Matrix shows that certain questions pertaining to separated distances are easy to score points on and nearly every application does.

Points are also awarded for practices, such as concrete manure storage structures, that are the industry standard. Other questions requiring air-quality monitoring, the installation of filters to reduce odors, demonstrating community support, implementing a worker safety and protection plan, or adopting an approved comprehensive nutrient management plan are almost never answered.
