A bill for an act relating to monitoring the application of manure originating from a confinement feeding operation, and making penalties applicable.

SF 2356 requires owners of larger livestock operations (those needing manure management plans) to monitor manure application near surface water or groundwater sources. If weather or conditions increase spill risk, they must report potential discharges to the Iowa Department of Natural Resources (DNR). The DNR will publish these reports online and investigate affected sites. This applies to operations exceeding 500 animal units, which are already required to submit manure management plans under existing law.
