Any rules adopted pursuant to this subsection shall be no more stringent than requirements under the federal Act.3.  If the open feedlot operation is designed, constructed, and operated in accordance with the requirements of an open feedlot effluent control system as provided in rules adopted by the commission, the operation shall be deemed to be in compliance with this section, unless a discharge from the operation causes a violation of state water quality standards as provided in chapter 455B, subchapter III.4.  The following shall apply to an open feedlot operation which has an animal unit capacity of one thousand animal units or more:a.(1)  The open feedlot operation shall not discharge open feedlot effluent from an open feedlot operation structure into any waters of the United States, unless the discharge is pursuant to an NPDES permit.(2)  The open feedlot operation shall not be required to be issued an NPDES permit if the operation does not discharge open feedlot effluent into any waters of the United States.b.  The control of open feedlot effluent originating from the open feedlot operation may be accomplished by the use of a solids settling facility, settled open feedlot effluent basin, alternative technology system, or any other open feedlot effluent control structure or practice approved by the department. The department may require the diversion of surface drainage prior to contact with an open feedlot operation structure. Solids shall be settled from open feedlot effluent before the effluent enters a settled open feedlot effluent basin or alternative technology system.2005 Acts, ch 136, §14, 2007 Acts, ch 126, §82, 2008 Acts, ch 1191, §145, 148, 2015 Acts, ch 92, §38 – 40, 2021 Acts, ch 76, §150Referred to in 459A.205, 459A.303, 459A.402459A.402Open feedlot effluent control — alternative control practices.If because of topography or other factors related to the site of an open feedlot operation it is economically or physically impractical to comply with open feedlot effluent control requirements using an open feedlot control method in section 459A.401, the department shall allow the use of other open feedlot effluent control practices if those practices will provide an equivalent level of open feedlot effluent control that would be achieved by using an open feedlot effluent control method pursuant to section 459A.401.2005 Acts, ch 136, §15459A.403Solids stockpiling.A person may stockpile solids, subject to all of the following:1.a.  The person shall not stockpile the solids within the following distances:(1)  Four hundred feet from a designated area other than a high-quality water resource.(2)  Eight hundred feet from a high-quality water resource.b.  The person shall not stockpile solids within two hundred feet from a terrace tile inlet or surface tile inlet unless the solids are maintained in a manner that will not allow precipitation-induced runoff to drain from the solids to the terrace tile inlet or surface tile inlet.c.  The person shall not stockpile solids in a grassed waterway or where water pools on the soil surface.d.  The person shall not stockpile solids on land having a slope of more than three percent unless methods, structures, or practices are implemented to contain the stockpiled solids, including but not limited to using hay bales, silt fences, temporary earthen berms, or other effective measures, and to prevent or diminish precipitation-induced runoff from the stockpiled solids.2.  The person must remove the stockpiled solids and apply them in accordance with the provisions of this chapter, including but not limited to section 459A.410, within six months after the solids are stockpiled.2006 Acts, ch 1088, §5,6459A.404Animal truck wash facility construction regulations.1.a.  An animal truck wash effluent structure shall not be constructed or expanded within one thousand two hundred fifty feet from a residence not owned by the titleholder of the animal truck wash facility, a commercial enterprise, a bona fide religious institution, an educational institution, or a public use area, as those terms are defined in section 459.102, and as provided in rules adopted by the commission pursuant to sections 459.103 and 459A.104.b.  An animal truck wash effluent structure shall not be constructed or expanded within one hundred feet from a public thoroughfare as defined in section 459.102.c.  Paragraph “a” does not apply if a residence, educational institution, commercial enterprise, or bona fide religious institution was constructed or expanded, or if the boundaries of the public use area were expanded, after the date that the animal truck wash facility was established.
