Nutrient management planning
A Concentration Animal Feeding Operation (CAFO) Water Pollutant Discharge Elimination System (WPDES) permit requires a field-specific, phosphorus-based nutrient management plan (NMP) that outlines the amounts, timing, locations, methods and other aspects related to land application of manure and process wastewater. Implementation of a NMP helps prevent or minimize manure or other wastewater runoff from fields to surface waters or groundwater. Nutrient management planning also ensures applied nutrients meet crop needs.
Nutrient management planning can be complicated and take a considerable amount of time and effort. One NMP may cover thousands of acres and contain over 100 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 application rates, methods and timing for manure and process wastewater;
- field soil erosion and phosphorus delivery to surface waters calculations;
- nutrient crediting;
- maps showing field-specific spreading restrictions and soils;
- manure spreading field-specific reports and procedures; and
- detailed plan narratives.
An ATCP 50.48 qualified nutrient management planner must develop or review and sign a CAFO’s NMP. DNR approval of a CAFO NMP requires submitting a plan that is consistent with all NR 243.14, Wis. Adm. Code requirements.

Annual NMP reporting requirements
All CAFO permittees are required to submit to the department annual and daily spreading information, monitoring reports and other information requested by the department on an annual basis. This annual reporting is divided into two reports: 1) Annual Report, typically due January 31 of each year, and 2) Nutrient Management Plan update, typically due March 31 of each year.

Substantial revisions to a CAFO NMP
All substantial revisions to a CAFO NMP are required to be public noticed and are posted for a 14-day public notice period. A substantial revision is defined as a change that will increase the risk of pollutant (nitrogen or phosphorus) transport to navigable water. Anyone can view and track substantial revisions that are posted for public notice at the department’s Water permit applications web page. The department has created guidance 3800-2014-01 on what constitutes a substantial substantial revision to a CAFO NMP and the public input process for these revisions. Instructions 3800-2015-10 are available on how permittees can submit a request for a substantial NMP modification.

Annual CAFO workshops
The Department of Natural Resource’s CAFO program in cooperation with UW-Extension hold annual CAFO workshops during the first few weeks of February. These workshops are typically held in various locations throughout the state and cover a wide variety of topics specific to CAFOs. Presentations from the 2015 and 2016 workshops are posted below.
