Iowa Admin. Code r. 567-65.209

Current through Register Vol. 47, No. 8, October 30, 2024

Rule 567-65.209 - NMP requirements

(1) The owner of an open feedlot operation that has an animal unit capacity of 1,000 animal units or more or that is required to be issued an NPDES permit shall develop and implement an NMP meeting the requirements of this rule. The owner of an open feedlot operation who seeks to obtain or is required to be issued an NPDES permit shall develop and implement an NMP meeting the requirements of this rule no later than the date on which the NPDES permit becomes effective. For the purpose of this rule, requirements pertaining to open feedlot effluent also apply to settled open feedlot effluent and settleable solids.

(2) Not more than one open feedlot operation shall be covered by a single NMP. For an open feedlot operation that is required to have an NPDES permit and the AFO includes an open feedlot operation and a confinement feeding operation, the NMP must include both the open feedlot operation and the confinement feeding operation if the confinement feeding operation does not have an MMP. If the confinement feeding operation portion of the AFO does have an MMP as required in rules 567-65.110 (455B,459,459B) and 567-65.111(455B,459,459B), the confinement feeding operation portion shall not be included in the NMP; however, in that event, the MMP must be amended to include the information specified in paragraph 65.209(8)"e."

(3) A person shall not remove manure, process wastewater or open feedlot effluent from an open feedlot operation structure that is part of an open feedlot operation for which an NMP is required under this rule, unless the department approves an NMP as required in this rule.

(4) The department shall not approve an application for a permit to construct a settled open feedlot effluent basin or AT system unless the owner of the open feedlot operation applying for approval submits an NMP together with the application for the construction permit as provided in rule 567-65.203 (455B,459A). The owner shall also submit proof that the owner has published a notice for public comment as provided in subrule 65.209(7).

(5) If a construction permit is required as provided in rule 567-65.203 (455B,459A), the department shall approve or disapprove the NMP as part of the construction permit application. If a construction permit is not required, the department shall approve or disapprove the NMP within 60 days from the date that the department receives the NMP.

(6) Prior to approving or disapproving an NMP as required in this rule, the department may receive comments exclusively to determine whether the NMP is submitted according to procedures required by the department and that the NMP complies with the provisions of this rule.

(7) Public notice.

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 manure, process wastewater, or open feedlot effluent that originates from the open feedlot operation may be applied under the terms and conditions of the NMP.

b. The notice for public comment shall include all of the following:

(1) The name of the owner of the open feedlot operation submitting the NMP.

(2) The name of the township where the open feedlot operation is or is proposed to be located and the name of the township where manure, process wastewater, or open feedlot effluent originating from the open feedlot operation may be applied.

(3) The animal unit capacity of the open feedlot operation.

(4) The time when and the place where the NMP may be examined as provided in Iowa Code section 22.2.

(5) Procedures for providing public comment to the department. The notice shall also include procedures for requesting a public hearing conducted by the department. The department is not required to conduct a public hearing if it does not receive a request for the public hearing within ten days after the first publication of the notice for public comment as provided in this subrule. If such a request is received, the public hearing must be conducted within 30 days after the first date that the notice for public comment was published.

(6) A statement that a person may acquire information relevant to making comments under this subrule by accessing the department's Internet website. The notice for public comment shall include the address of the department's Internet website as required by the department.

(8) Except as provided in paragraph 65.209(8)"f," an NMP shall include all of the following:

a. An estimate of the nitrogen and phosphorus concentration of manure, process wastewater and open feedlot effluent and an estimate of the manure, process wastewater, and open feedlot volume or weight produced by the open feedlot operation, in accordance with subrule 65.111(3).

b. Application rate calculations consistent with the requirements of subrule 65.111(12). The 100 pounds of available nitrogen per acre limitation specified in paragraph 65.111(13)"c" (applicable to open feedlot operations and combined open feedlot operations and confinement operations with an NPDES permit because of requirements in subrule 65.111(4)) pertaining to liquid manure applied to land currently planted to soybeans or to land where a soybean crop is planned applies only to liquid manure, process wastewater or settled open feedlot effluent.

c. The location of manure application. If the application is on land other than land owned or rented for crop production by the owner of the open feedlot operation, the plan shall include a copy of each written agreement executed by the owner of the open feedlot operation and the landowner or the person renting the land for crop production where the manure, process wastewater or open feedlot effluent may be applied. The written agreement shall indicate the number of acres on which the manure, process wastewater or effluent may be applied and the length of the agreement.

d. A phosphorus index of each field in the nutrient management plan, as defined in paragraph 65.111(12)"a," including the factors used in the calculation. A copy of the NRCS phosphorus index detailed report shall satisfy the requirement to include the factors used in the calculation.

e. Information that shows all of the following:

(1) There is adequate storage for manure, process wastewater, stockpiled manure and open feedlot effluent, including procedures to ensure proper operation and maintenance of the storage structures.

(2) The proper management of animal mortalities to prevent discharge of pollutants to surface water and 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.

(3) Surface drainage prior to contact with an open feedlot structure is diverted, as appropriate, from the open feedlot operation.

(4) Animals kept in the open feedlot operation do not have direct contact with any waters of the United States.
