JFAN often receives inquiries about where CAFO’s are spreading manure from their operations. The Iowa Department of Natural Resources (DNR) does not keep computerized records of Manure Management Plans, or MMPs, making it very difficult for the average person to find information on exactly where manure is applied.
JFAN has created a database of current MMP’s from the DNR for all CAFO operators in and outside of Jefferson County who apply manure to fields within Jefferson County. This database can be used to identify who is applying manure as well as where and how it is being applied. This is invaluable information that can be used as a community resource for property owners and potential buyers who will be affected by manure applications.
Because the fields do not have standardized designations, we have also created a color-coded visual mapping system that makes it easy to see exactly which fields receive manure, and in particular, if more than one CAFO is applying to the same field.
It is important to note that the all the information shown was gathered from records submitted to the DNR by CAFO operators and the information available is only for larger operations that have at least 500 animal units, the equivalent of 1250 hogs.
Any operation that has fewer than 500 animal units, known as SAFOs or Small Animal Feeding Operations, is not required to submit a Master Matrix. Because the DNR has no information available on SAFOs, neither does JFAN.
