Draft Comprehensive Nutrient Management Planning Technical Guidance
Subpart C - Exhibits
Exhibit 15, Comprehensive Nutrient Management Plan - Format and Content
A comprehensive nutrient management plan (CNMP) should address
all land units that the animal feeding operation (AFO) owner/operator owns or
has decision-making authority over and on which manure and organic by-products
will be generated, handled, stored, or applied. This Exhibit describes the
general contents of a CNMP and lists suggested items under each major section.
The intent of this guidance is to help to maintain quality and provide
appropriate documentation of a CNMP. The precise content of a CNMP will vary as
it is tailored to the meet the needs of the AFO owner and/or operator.
