a. The owner of an open feedlot operation which has an animal unit capacity of one thousand animal units or more or which is required to be issued an NPDES permit.
b. The owner of an animal truck wash facility, other than a small animal truck wash facility, which has an animal truck wash effluent structure. However, for an animal truck wash facility which is part of a confinement feeding operation, in lieu of submitting a nutrient management plan, the owner of the animal truck wash facility may submit an original manure management plan and an updated manure management plan to the department as required by section 459.312, including rules adopted by the commission pursuant to that section.
2. Not more than one open feedlot operation shall be covered by a single nutrient management plan.
3. a. A person shall not remove open feedlot effluent from an open feedlot operation structure or animal truck wash effluent from an animal truck wash effluent structure for which a nutrient management plan is required under this section, unless the department approves a nutrient management plan as required in this section.
b. Notwithstanding paragraph “a”, the commission may adopt rules allowing a person to remove effluent from an open feedlot operation structure or animal truck wash effluent structure until the nutrient management plan is approved or disapproved by the department according to terms and conditions required by rules adopted by the commission.
4. The department shall not approve an application for a permit to construct a settled open feedlot effluent basin or animal truck wash effluent structure, unless the owner of the open feedlot operation or animal truck wash facility, applying for approval submits a nutrient management plan together with the application for the construction permit as provided in section 459A.205. The owner of the open feedlot operation shall also submit proof that the owner has published a notice for public comment as provided in this section. The department shall approve or disapprove the nutrient management plan as provided in section 459A.201.
5. For an animal feeding operation, prior to approving or disapproving a nutrient management plan as required in this section, the department may receive comments exclusively to determine whether the nutrient management plan is submitted according to procedures required by the department and that the nutrient management plan complies with the provisions of this chapter.
a. The owner of the open feedlot operation shall publish a notice for public comment in a newspaper having a general circulation in the county where the open feedlot operation is or is proposed to be located and in the county where open feedlot effluent, which originates from the open feedlot operation, may be applied under the terms and conditions of the nutrient management plan.

The department shall include information regarding the time when, the place where, and the manner in which persons may participate in a public hearing as provided in this subsection.
6. A nutrient management plan must be authenticated by the owner of the open feedlot operation or the owner of the animal truck wash facility as required by the department in accordance with section 459A.201.
7. A nutrient management plan shall include all of the following:
a. Restrictions on the application of open feedlot effluent or animal truck wash effluent based on all of the following:
(1) Calculations necessary to determine the land area required for the application of the effluent based on nitrogen use levels in order to obtain optimum crop yields according to a crop schedule specified in the nutrient management plan, and according to requirements adopted by the department.
(2) A phosphorus index established pursuant to section 459.312.
b. Information relating to the application of the effluent, including all of the following:
(1) Nutrient concentrations of the effluent.
(2) Application methods, the timing of the application, and the location of the land where the application occurs.
c. If the application is on land other than land owned or rented for crop production by the owner, the plan shall include a copy of each written agreement executed by the owner and the landowner or the person renting the land for crop production where the effluent may be applied.
d. An estimate of the effluent volume or weight produced by the open feedlot operation or animal truck wash facility.
e. Information which shows all of the following:
(1) There is adequate storage for open feedlot effluent or animal truck wash effluent, including procedures to ensure proper operation and maintenance of an open feedlot operation structure or animal truck wash effluent structure.
(2) For an animal feeding operation, all of the following:
(a) The proper management of animal mortalities to ensure that animals are not disposed of in an open feedlot operation structure or a treatment system that is not specifically designed to treat animal mortalities.
(b) Animals kept in the open feedlot operation do not have direct contact with any waters of the United States.
(3) (a) Surface drainage prior to contact with an open feedlot structure is diverted, as appropriate, from the open feedlot operation.
(b) Surface drainage prior to contact with an animal truck wash facility is diverted, as appropriate, from the animal truck wash facility.
(4) Chemicals or other contaminants handled on-site are not disposed of in an open feedlot operation structure, an animal truck wash facility, or a treatment system that is not specifically designed to treat such chemicals or contaminants.
8. If an open feedlot operation uses an alternative technology system as provided in section 459A.303, the nutrient management plan is not required to provide for settled effluent that enters the alternative technology system.
9. The owner of an open feedlot operation or animal truck wash facility who is required to develop and implement a nutrient management plan shall maintain a current nutrient management plan and maintain records sufficient to demonstrate compliance with the nutrient management plan.
