Nutrient management planning
A Concentrated Animal Feeding Operation Water (CAFO) Pollutant Discharge Elimination System (WPDES) permit requires an annual and field-specific nutrient management plan (NMP). Implementation of a NMP helps prevent or minimize manure or other wastewater runoff from fields to surface water or groundwater. Nutrient management planning also ensures applied nutrients meet, but don’t exceed, crop needs.
NMP requirements and DNR approval
Nutrient management planning is complicated and takes considerable time and effort. These plans may cover thousands of acres and over one hundred fields. Planning may be for areas with multiple crops and different soils with different nutrient requirements and limitations. Nutrient management plans require:
- field soil testing reports;
- planned or actual rates, methods and timing for manure and process wastewater application;
- field soil erosion and phosphorus delivery to surface waters calculations and nutrient credits;
- maps showing field-specific manure spreading restrictions and soils;
- manure spreading field-specific reports/procedures; and
- detailed plan narratives.
An ATCP 50.48 qualified nutrient management planner must develop a CAFO’s NMP. DNR approval of a CAFO Nutrient Management Plan requires submitting a plan that is consistent with all NR 243.14 requirements.

NMP reporting requirements
In addition to annual and daily spreading information, CAFOs must follow a compliance calendar, submit quarterly monitoring reports, and submit annual reports.
