ARC 2798C
ENVIRONMENTAL PROTECTION COMMISSION[567]
Adopted and Filed
Pursuant to the authority of Iowa Code sections 459.103 and 459A.104, the Environmental Protection Commission (Commission) hereby amends Chapter 65, “Animal Feeding Operations,” Iowa Administrative Code.
The purpose of the amendments to the animal feeding operation rules is to:
1. Adopt changes due to recent legislative action as follows:
2012 Iowa Acts, Senate File 2172: This legislation exempts swine farrowing and gestating operations from the definition of “qualified confinement feeding operation” and the operating requirements associated with this type of facility if the swine farrowing and gestating operations meet this definition solely because they added replacement breeding swine as defined in Iowa Code section 459.102(46).
2012 Iowa Acts, House File 2292: This legislation allows fish production facilities the option to operate as confinement feeding operations or as facilities regulated by the wastewater regulations.
2013 Iowa Acts, House File 512: This legislation allows confinement feeding operations to discontinue use of buildings, without dismantling the livestock production components of the buildings, in order to meet the definition of a small animal feeding operation (SAFO).
2015 Iowa Acts, House File 583: This legislation allows animal truck wash facilities to meet animal feeding operations regulations for design, construction and operation. It also incorporates by reference the applicable federal National Pollutant Discharge Elimination System (NPDES) permit requirements for open feedlot operations, as had previously been done in statute for confinement feeding operations.
2. Allow solids from open feedlot operations to be regulated by the Iowa Department of Agriculture and Land Stewardship (IDALS) as bulk dry animal nutrient products (Iowa Code chapter 200A).
3. Provide better clarification of requirements in rules and rescind unnecessary and outdated rules, lists and Internet addresses. The amendments will implement a portion of the five-year rules review plan that the Department of Natural Resources (Department) is carrying out to accomplish the requirements of Iowa Code section 17A.7(2).
Some of the changes designed to provide clarification of the rule requirements include: (1) a revised version of the definition of “public use area” in an effort to better define the term; (2) an updated listing of Iowa lakes (Table 2 of Chapter 65) to ensure that all the lakes are accounted for and properly protected through the facility-siting requirements; (3) clarification regarding which structures are to be used for measuring separation distances; (4) clarification of the scope of any landowner waiver of a separation distance; and (5) additional language regarding NPDES permit requirements to be consistent with the federal rule.
Notice of Intended Action was published in the Iowa Administrative Bulletin on April 13, 2016, as ARC 2496C. Public hearings were held on May 23, 2016, in Windsor Heights, Iowa; on May 24, 2016, in Carroll, Iowa; on May 25, 2016, in Spencer, Iowa; on May 26, 2016, in Mason City, Iowa; on May 31, 2016, in Ainsworth, Iowa; and on June 3, 2016, in Calmar, Iowa. Public comments were received and considered. A responsiveness summary has been prepared and is available at: http://www.iowadnr.gov/Environmental-Protection/Land-Quality/Animal-Feeding-Operations/AFO-Rules-Regulations.
As a result of the written and oral comments, the following change has been made to the amendments as published in the Notice of Intended Action:
The mailing address and telephone number for the owner and contact person for a confinement feeding operation will not be removed from the requirements to be submitted with a manure management plan. In Item 44 of the Notice of Intended Action, deletion of this information from the rule was proposed. In light of the comments received, the Commission decided to leave this required information in subparagraphs 65.17(1)“c”(1) and (2) and, therefore, did not adopt the proposed amendments in Item 44 of the Notice. Subsequent items have been renumbered accordingly.
After analysis and review of this rule making, the Commission has determined that most of the amendments will have no impact on private sector jobs; however, there are some changes that may have a positive financial impact. The complete jobs impact statement is available from the Department upon request.
These amendments are intended to implement Iowa Code sections 459.102, 459.103, 459.301, 459.312A, and 459.320 and Iowa Code chapter 459A.
These amendments shall become effective on December 14, 2016.
The following amendments are adopted.
	Item 1. Rescind rule 567—65.1(459,459B) and adopt the following new rule in lieu thereof:
567—65.1(459,459B) Definitions and incorporation by reference. In addition to the definitions in Iowa Code sections 455B.101, 455B.171 and 459.102 and in 567—Chapter 60, the following definitions shall apply to Division I of this chapter:
	65.1(1) Definitions.
“Abandoned confinement feeding operation structure” means the confinement feeding operation structure has been razed, removed from the site of a confinement feeding operation, filled in with earth, or converted to uses other than a confinement feeding operation structure so that it cannot be used as a confinement feeding operation structure without significant reconstruction.
“Adjacent—air quality” means, for the purpose of determining separation distance requirements pursuant to 567—65.11(459,459B), that two or more confinement feeding operations are adjacent if they have animal feeding operation structures that are separated at their closest points by less than the following:
	1.	1,250 feet for a confinement feeding operation having an animal unit capacity of less than 1,250 animal units for swine maintained as part of a farrowing and gestating operation, less than 2,700 animal units for swine maintained as part of a farrow-to-finish operation, less than 4,000 animal units for cattle maintained as part of a cattle operation, or less than 3,000 animal units for any other confinement feeding operation, or for a confinement feeding operation consisting of dry bedded confinement feeding operation structures.
	2.	1,500 feet for a confinement feeding operation having an animal unit capacity of 1,250 or more but less than 2,000 animal units for swine maintained as part of a swine farrowing and gestating operation, 2,700 or more but less than 5,400 animal units for swine maintained as part of a farrow-to-finish operation, 4,000 or more but less than 6,500 animal units for cattle maintained as part of a cattle operation, or for any other confinement feeding operation having an animal unit capacity of 3,000 or more but less than 5,000 animal units.
	3.	2,500 feet for a confinement feeding operation having an animal unit capacity of 2,000 or more animal units for swine maintained as part of a swine farrowing and gestating operation, 5,400 or more animal units for swine maintained as part of a farrow-to-finish operation, or 6,500 or more animal units for cattle maintained as part of a cattle operation, or for any other confinement feeding operation with 5,000 or more animal units.
	4.	The distances in “1” to “3” above shall only be used to determine that two or more confinement feeding operations are adjacent if at least one confinement feeding operation structure was constructed on or after March 21, 1996.
	5.	To determine if two or more confinement feeding operations are adjacent, for the purpose of determining the separation distance requirements, the animal unit capacity of each individual operation shall be used. If two or more confinement feeding operations do not have the same animal unit capacity, the greater animal unit capacity shall be used to determine the separation distance.
	6.	Dry manure that is stockpiled within a distance of 1,250 feet from another stockpile shall be considered part of the same stockpile.
“Adjacent—water quality” means, for the purpose of determining the construction permit requirements pursuant to 567—65.7(459,459B) and manure management plan requirements pursuant to 567—65.16(459,459B), that two or more confinement feeding operations are adjacent if they have confinement feeding operation structures that are separated at their closest points by less than the following:
	1.	1,250 feet for confinement feeding operations having a combined animal unit capacity of less than 1,000 animal units.
	2.	2,500 feet for confinement feeding operations having a combined animal unit capacity of 1,000 or more animal units.
	3.	The distances in “1” and “2” above shall only be used to determine that two or more confinement feeding operations are adjacent if at least one confinement feeding operation structure is constructed or expanded on or after May 21, 1998.
“Aerobic structure” means an animal feeding operation structure other than an egg washwater storage structure which relies on aerobic bacterial action which is maintained by the utilization of air or oxygen and which includes aeration equipment to digest organic matter. Aeration equipment shall be used and shall be capable of providing oxygen at a rate sufficient to maintain an average of 2 milligrams per liter dissolved oxygen concentration in the upper 30 percent of the depth of manure in the structure at all times.
“Agricultural drainage well” means a vertical opening to an aquifer or permeable substratum which is constructed by any means including but not limited to drilling, driving, digging, boring, augering, jetting, washing, or coring and which is capable of intercepting or receiving surface or subsurface drainage water from land directly or by a drainage system.
“Agricultural drainage well area” means an area of land where surface or subsurface water drains into an agricultural drainage well directly or through a drainage system connecting to the agricultural drainage well.
“Alluvial aquifer area” means an area underlaid by sand or gravel aquifers situated beneath flood plains along stream valleys and includes alluvial deposits associated with stream terraces and benches, contiguous windblown sand deposits, and glacial outwash deposits.
“Alluvial soils” means soils formed in materials deposited by moving water.
“Anaerobic lagoon” means an unformed manure storage structure if the primary function of the structure is to store and stabilize manure, the structure is designed to receive manure on a regular basis, and the structure’s design waste loading rates provide that the predominant biological activity is anaerobic. An anaerobic lagoon does not include the following:
	1.	A runoff control basin or a settled open feedlot effluent basin which collects and stores only precipitation-induced runoff from an open feedlot operation.
	2.	An anaerobic treatment system that includes collection and treatment facilities for all off gases.
“Animal” means cattle, swine, horses, sheep, chickens, turkeys, goats, fish, or ducks.
“Animal capacity” means the maximum number of animals which the owner or operator will confine in an animal feeding operation at any one time. In a confinement feeding operation, the animal capacity of all confinement buildings will be included in the determination of the animal capacity of the operation, unless the building has been abandoned in accordance with the definition of “abandoned confinement feeding operation structure.”
“Animal feeding operation” means a lot, yard, corral, building, or other area in which animals are confined and fed and maintained for 45 days or more in any 12-month period, and all structures used for the storage of manure from animals in the operation. Except as required for an NPDES permit required pursuant to the Act, an animal feeding operation does not include a livestock market. Open feedlots and confinement feeding operations are considered to be separate animal feeding operations.
	1.	For purposes of water quality regulation, Iowa Code section 459.301provides that two or more animal feeding operations under common ownership or management are deemed to be a single animal feeding operation if they are adjacent or utilize a common area or system for manure disposal. For purposes of the air quality-related separation distances in Iowa Code section 459.202, Iowa Code section 459.201 provides that two or more animal feeding operations under common ownership or management are deemed to be a single animal feeding operation if they are adjacent or utilize a common system for manure storage. The distinction is due to regulation of animal feeding operations for water quality purposes under the Act. 40 CFR 122.23 sets out the requirements for an animal feeding operation and requires that two or more animal feeding operations under common ownership be considered a single operation if they adjoin each other or if they use a common area or system for disposal of wastes. However, this federal regulation does not control regulation of animal feeding operations for the purposes of the separation distances in Iowa Code section 459.202, and therefore the definition is not required by federal law to include common areas for manure disposal.
	2.	To determine if two or more animal feeding operations are deemed to be one animal feeding operation, the first test is whether the animal feeding operations are under common ownership or management. If they are not under common ownership or management, they are not one animal feeding operation. For purposes of water quality regulation, the second test is whether the two animal feeding operations are adjacent or utilize a common area or system for manure disposal. If the two operations are not adjacent and do not use a common area or system for manure disposal, they are not one animal feeding operation. For purposes of the separation distances in Iowa Code section 459.202, the second test is whether the two animal feeding operations are adjacent or utilize a common system for manure storage. If the two operations are not adjacent and do not use the same system for manure storage, they are not one animal feeding operation.
	3.	A common area or system for manure disposal includes, but is not limited to, use of the same manure storage structure, confinement feeding operation structure, egg washwater storage structure, stockpile, permanent manure transfer piping system or center pivot irrigation system. A common area or system for manure disposal does not include manure application fields included in a manure management plan or anaerobic digesters.
“Animal feeding operation structure” means a confinement building, manure storage structure, dry bedded confinement feeding operation structure, or egg washwater storage structure.
“Animal unit” means a unit of measurement based upon the product of multiplying the number of animals of each category by a special equivalency factor, as follows:

1. Slaughter and feeder cattle 			1.000	
2. Immature dairy cattle 			1.000	
3. Mature dairy cattle 			1.400	
4. Butcher or breeding swine weighing more than 55 pounds 			0.400	
5. Swine weighing 15 pounds or more but not more than 55 pounds 			0.100	
6. Sheep or lambs 			0.100	
7. Goats 			0.100	
8. Horses 			2.000	
9. Turkeys weighing 7 pounds or more 			0.018	
10. Turkeys weighing less than 7 pounds 		0.0085	
11. Broiler or layer chickens weighing 3 pounds or more 			0.010	
12. Broiler or layer chickens weighing less than 3 pounds 		0.0025	
13. Ducks 			0.040	
14. Fish 			0.001	
“Animal unit capacity” means a measurement used to determine the maximum number of animal units that may be maintained as part of an animal feeding operation at any one time, including as provided in Iowa Code sections 459.201 and 459.301. For dry bedded confinement feeding operations, “animal unit capacity” means the maximum number of animal units which the owner or operator confines in a dry bedded confinement feeding operation at any one time, including the animal unit capacity of all dry bedded confinement feeding operation buildings that are used to house cattle or swine in the dry bedded confinement feeding operation.
“Animal weight capacity” means the sum of the average weight of all animals in a confinement feeding operation when the operation is at full animal capacity. For confinement feeding operations with only one species, the animal weight capacity is the product of multiplying the animal capacity by the average weight during a production cycle. For operations with more than one species, the animal weight capacity of the operation is the sum of the animal weight capacities for all species.
Example 1. Bill wants to construct a confinement feeding operation with two confinement buildings and an earthen manure storage basin. The capacity of each building will be 900 market hogs. The hogs enter the building at 40 pounds and leave at 250 pounds. The average weight during the production cycle is then 145 pounds for this operation. The animal weight capacity of the operation is 145 pounds multiplied by 1,800 for a total of 261,000 pounds.
Example 2. Howard is planning to build a confinement feeding operation with eight confinement buildings and an egg washwater storage lagoon. The capacity of each building will be 125,000 laying hens. The hens enter the building at around 2.5 pounds and leave at around 3.5 pounds. The average weight during the production cycle for these laying hens is 3.0 pounds. Manure will be handled in dry form. The animal weight capacity of the operation is 3.0 pounds multiplied by 1,000,000 for a total of 3,000,000 pounds.
Example 3. Carol has an animal feeding operation with four confinement buildings with below floor formed concrete manure storage tanks and one open feedlot. One confinement building is a farrowing building with a capacity of 72 sows. One confinement building is a nursery building with a capacity of 1,450 pigs. The open feedlot contains 425 sows. Two of the confinement buildings are finishing buildings with a capacity of 1,250 market hogs. The farrowing building contains 72 sows at an average weight of 400 pounds for an animal weight capacity of 28,800 pounds. The nursery building contains 1,450 pigs with an average weight over the production cycle of 25 pounds for an animal weight capacity of 36,250 pounds. The two finishing buildings contain 2,500 market hogs (combined) with an average weight over the production cycle of 150 pounds for an animal weight capacity of 375,000 pounds. The total animal weight capacity of the confinement feeding operation is 440,050 pounds. The weights of the animals in open lots are not included in the calculation of the animal weight capacity of the confinement feeding operation.

Regardless of whether the department receives comments or an evaluation by a county board of supervisors, the department must render a determination or a preliminary determination to approve or disapprove an application for a construction permit within 60 days following the applicant’s delivery of an a complete application to the department. However, the applicant may deliver a notice requesting a continuance. Upon receipt of a notice, the time required for the county or department to act upon the application shall be suspended for the period provided in the notice, but for not more than 30 days after the department’s receipt of the notice. The applicant may submit more than one notice. However, the department may terminate an application if no action is required by the department for one year following delivery of the application to the board. The department may also provide for a continuance when it considers the application. The department shall provide notice to the applicant and the board of the continuance. The time required for the department to act upon the application shall be suspended for the period provided in the notice, but for not more than 30 days. However, the department shall not provide for more than one continuance. If review of the application is delayed because the application is incomplete, and the applicant fails to supply requested information within a reasonable time prior to the deadline for action on the application, the permit may be denied and a new application will be required if the applicant wishes to proceed.
The department will approve or disapprove an application as follows:
	a. 	If the county board of supervisors does not submit a construction evaluation resolution to the department, fails to submit an adopted recommendation, submits only comments, or fails to submit comments, the department shall approve the application if the application meets the requirements of this chapter and Iowa Code chapter chapters 455B, 459, 459A and 459B. The department will disapprove the application if it does not meet such requirements.
	b. 	If the board of supervisors for the county in which the confinement feeding operation is proposed to be constructed has filed a county construction evaluation resolution and submits an adopted recommendation to approve the construction permit application, which may be based on a satisfactory rating produced by the master matrix, to the department, the department shall preliminarily approve an application for a construction permit if the department determines that the application meets the requirements of this chapter and Iowa Code chapter chapters 455B, 459, 459A and 459B. The department shall preliminarily disapprove an application that does not satisfy the requirements of this chapter and Iowa Code chapter chapters 455B, 459, 459A and 459B regardless of the adopted recommendation of the board of supervisors.

	(1)	Unformed structures. The groundwater table around an unformed manure storage structure or earthen egg washwater storage structure may be artificially lowered to levels required in paragraph 65.15(7)“a” by using a gravity flow tile drainage system or other permanent nonmechanical system for artificial lowering of the groundwater table. Detailed engineering and soil drainage information shall be provided with a construction permit application for an unformed manure storage structure or earthen egg washwater storage structure to confirm the adequacy of the proposed permanent system to provide the required drainage without materially increasing the seepage potential of the site if a drainage system for artificially lowering the groundwater table will be installed. Drainage tiles shall not be located closer than 6 feet horizontally from the structure’s liquid surface at maximum operating depth. (See 65.15(1)“b” for monitoring and shutoff requirements for drainage tile lines installed to lower the groundwater table.) The level to which the groundwater table will be lowered will be considered to represent the seasonal high-water table. If a drainage tile around the perimeter of the basin is installed a minimum of two feet below the top of the basin liner to artificially lower the seasonal high-water table, the top of the basin’s liner may be a maximum of four feet below the seasonal high-water table which existed prior to installation of the perimeter tile system. Drainage tile lines shall be installed between the outside of the proposed toe of the berm and within 25 feet of the outside of the toe of the berm. Drainage tile lines shall be placed in a vertical trench and encased in granular material which extends upward to the level of the seasonal high-water table which existed prior to installation of the perimeter tile system. A device to allow monitoring of the water in the drainage tile lines installed to lower the groundwater table and a device to allow shutoff of the drainage tile lines shall be installed if the drainage tile lines do not have a surface outlet accessible on the property where the unformed manure storage structure is located.
	(2)	Formed structures. For a formed manure storage structure or a formed egg washwater storage structure, partially or completely constructed below the normal soil surface, a tile drainage system or other permanent system for artificial lowering of groundwater levels shall be installed around the structure if the groundwater table is above the bottom of the structure. (See 65.15(1)“b” 65.15(7)“b”(1) for monitoring and shutoff requirements for drainage tile lines installed to lower the groundwater table.)
	Item 34. Amend paragraph 65.15(7)“c” as follows:

	●	Unformed structures. For an unformed manure storage structure, each monitoring well may be installed in the existing boreholes resulting from the corings required in subrule 65.15(6).
	●	Formed structures. For a formed manure storage structure, at least three temporary monitoring wells shall be installed as close as possible to three corners of the structure, with one of the wells close to the corner of deepest excavation. If the formed structure is circular, the three monitoring wells shall be equally spaced and one well shall be placed at the point of deepest excavation.
	2.	Test pits. The department may allow use of test pits in lieu of temporary monitoring wells if seasonal variation in climatic patterns, soil and geologic conditions prevent accurate determination of the seasonal high water table or prior to the construction of an unformed manure storage structure liner to ensure that the required separation distance to the groundwater table is being met. The bottom of each test pit shall be at least 2 feet below the floor of the manure storage structure or egg washwater storage structure. Each pit shall be allowed to remain open and unaltered for a minimum of seven days for viewing by the department or NRCS qualified staff for the determination of soil characteristics and related groundwater influence. Adequate protection (temporary berms and covers) shall be provided to prevent surface runoff from entering the test pits. One test pit shall be located in each corner and one in the center of the proposed manure control structure, unless otherwise specified by the department. Test pits shall be backfilled and compacted to achieve the seepage loss as outlined in subrule 65.15(11). A description of the materials present in the test pit shall be documented by all of the following:
	●	Digital photos;
	●	Description of soils including mottling;
	●	Construction specifications; and

“Abandoned” means an open feedlot operation structure that has been razed, removed from the site of an open feedlot operation, filled in with earth, or converted to uses other than an open feedlot operation structure so that it cannot be used as an open feedlot operation structure without significant reconstruction.
“Adjacent.” Two or more open feedlot operations are defined as adjacent if both of the following occur:
	1.	At least one open feedlot operation structure is constructed on or after July 17, 2002.
	2.	An open feedlot operation structure which is part of one open feedlot operation is separated by less than 1,250 feet from an open feedlot operation structure which is part of the other open feedlot operation.
“Alternative technology settled open feedlot effluent control system” or “AT system” means use of an open feedlot effluent control technology other than a conventional runoff containment system to control and dispose of settled open feedlot effluent. The department may allow an open feedlot operation covered by the NPDES permit application requirements of 567—65.102(459A) or 567—65.103(455B,459A) to use an AT system, provided the open feedlot operation satisfactorily demonstrates the AT system will provide an equivalent level of performance to that achieved by a runoff containment system that is designed and operated as required by statute, 567—subrule 62.4(12) and Division II of this chapter. Demonstration of equivalent performance must include submitting results of computer modeling which compares the predicted performance of the proposed system with that of a conventional runoff containment system over the same period. The specific requirements which must be met for an open feedlot operation to qualify for use of an AT system and the information which must be submitted to the department are outlined in rule 567—65.110(459A).
Design requirements have been established for two types of AT systems. These are a vegetative infiltration basin (VIB) followed by a vegetative treatment area (VTA) and a stand-alone vegetative treatment area (VTA). If other AT systems are developed that meet the equivalent performance standard established under EPA’s CAFO rules, the department will consider their acceptance on a case-by-case basis.
“Animal” means cattle, swine, horses, sheep, chickens, turkeys, goats, fish, or ducks.
“Animal capacity” means the maximum number of animals which the owner or operator will confine in an open feedlot operation at any one time.
“Animal feeding operation” or “AFO” means a lot, yard, corral, building, or other area in which animals are confined and fed and maintained for 45 days or more in any 12-month period, and all structures used for the storage of manure from animals in the operation. Except as required for an NPDES permit required pursuant to the Act, an animal feeding operation does not include a livestock market.

12. Goats			0.100	
13. Ducks			0.040	
14. Fish			0.001	
“Animal unit capacity” means a measurement used to determine the maximum number of animal units that may be maintained as part of an open feedlot operation. Only for purposes of determining whether an open feedlot operation must obtain an NPDES permit, the animal unit capacity of the animal feeding operation shall include the animal unit capacities of both the open feedlot operation and the confinement feeding operation if all of the following occur:
	1.	The animals in the open feedlot operation and the confinement feeding operation are all in the same category of animals as used in the definitions of “large CAFO” and “medium CAFO” in 40 CFR Part 122.

Iowa Code section 459A.103 provides that two or more open feedlot operations under common ownership or management are deemed to be a single open feedlot operation if they are adjacent or utilize a common area or system for open feedlot effluent disposal. To determine if two or more open feedlot operations are deemed to be one open feedlot operation, the first test is whether the open feedlot operations are under common ownership or management. If they are not under common ownership or management, they are not one open feedlot operation. The second test is whether the two open feedlot operations are adjacent or utilize a common area or system for open feedlot effluent disposal. If the two operations are not adjacent and do not use a common area or system for open feedlot effluent disposal, they are not one open feedlot operation.
“Open feedlot operation structure” means an open feedlot, a settled open feedlot effluent basin, a solids settling facility, or an AT system. “Open feedlot operation structure” does not include a manure storage structure as defined in Iowa Code section 459.102.

Also included in the definition of production area is any area used in the storage, handling, treatment, or disposal of mortalities.
“Professional engineer” means a person engaged in the practice of engineering as defined in Iowa Code section 542B.2 who is issued a certificate of licensure as a professional engineer pursuant to Iowa Code section 542B.17.
“Release” means an actual, imminent or probable discharge of process wastewater, manure, open feedlot effluent, settled open feedlot effluent, or settleable solids from an open feedlot operation structure to surface water, groundwater, or an actual, imminent or probable discharge directly to a drainage tile line or intake resulting from storing, handling, transporting or land-applying process wastewater, manure, open feedlot effluent, settled open feedlot effluent or settleable solids.
“Settleable solids,” “scraped solids,” or “solids” means that portion of the effluent that meets all the following requirements:
	1.	The solids do not flow perceptibly under pressure.
	2.	The solids are not capable of being transported through a mechanical pumping device designed to move a liquid.
	3.	The constituent molecules of the solids do not flow freely among themselves but do show the tendency to separate under stress.
“Settled open feedlot effluent” means a combination of manure, precipitation-induced runoff, or other runoff originating from an open feedlot after its settleable solids have been removed.
“Settled open feedlot effluent basin” or “runoff control basin” means a covered or uncovered impoundment which is part of an open feedlot operation, if the primary function of the impoundment is to collect and store settled open feedlot effluent. An animal truck wash facility may be part of an open feedlot operation. An animal truck wash effluent structure may be the same as a settled open feedlot effluent basin that is part of the open feedlot operation, so long as the primary function of such impoundment is to collect and store effluent from both the animal truck wash facility and the open feedlot operation.
“Shallow well” means a well located and constructed in such a manner that there is not a continuous layer of low permeability soil or rock (or equivalent retarding mechanism acceptable to the department) at least 5 feet thick, the top of which is located at least 25 feet below the normal ground surface and above the aquifer from which water is to be drawn.
“Solids settling facility” means a basin, terrace, diversion, or other structure or solids removal method which is part of an open feedlot operation and which is designed and operated to remove settleable solids from open feedlot effluent. A “solids settling facility” does not include a basin, terrace, diversion, or other structure or solids removal method which retains the liquid portion of open feedlot effluent for more than seven consecutive days following a precipitation event.
“Stockpile” means any accumulation of manure, scraped solids, settleable solids or combination of manure and solids located outside of the open feedlot or animal truck wash facility or outside of an area that drains to an open feedlot or animal truck wash facility, where the scraped manure or solids are stored for less than six months.
“Unformed settled open feedlot effluent basin” means a settled open feedlot effluent basin, other than a formed settled open feedlot effluent basin.
“Vegetative infiltration basin” or “VIB” means an open feedlot operation structure in which settled open feedlot effluent is discharged into a relatively flat basin area which is bermed to prevent entry or discharge of surface water flows and is planted to permanent vegetation. An extensive tile system installed at a depth of three to five feet is used to collect infiltrated settled open feedlot effluent from the VIB and discharge it into a VTA for further treatment. As opposed to wetlands, which are designed to maintain a permanent water level, a VIB is designed to maximize water infiltration into the soil and thus normally will have standing water for only short periods of time. Removal of settleable solids is required prior to discharge of open feedlot effluent into the VIB. Soil suitability is essential to ensure adequate filtration and treatment of pollutants. Periodic harvesting of vegetation is required.
“Vegetative treatment area” or “VTA” means an open feedlot operation structure in which settled open feedlot effluent is discharged into areas which are level in one dimension and have a slight slope (less than 5 percent) in the other dimension and are planted to relatively dense permanent vegetation. Settled open feedlot effluent must be discharged evenly across the top width of the VTA and allowed to slowly flow downslope through the VTA. Level spreaders or other practices may be required to maintain even flow throughout the length of the VTA. Management to maintain a dense vegetation cover is required, as is periodic harvesting of vegetation.
“Water of the state” means any stream, lake, pond, marsh, watercourse, waterway, well, spring, reservoir, aquifer, irrigation system, drainage system, and any other body or accumulation of water, surface or underground, natural or artificial, public or private, which are contained within, flow through or border upon the state or any portion thereof.
“Water well” means an excavation that is drilled, cored, bored, augered, washed, driven, dug, jetted, or otherwise constructed for the purpose of exploring for groundwater, monitoring groundwater, utilizing the geothermal properties of the ground, or extracting water from or injecting water into the aquifer. “Water well” does not include an open ditch or drain tiles or an excavation made for obtaining or prospecting for oil, natural gas, minerals, or products mined or quarried.
“Waters of the United States” means the same as defined in 40 CFR 122.2.

Complaints of violations of Iowa Code chapter 455B, 459, 459A, or 459B or these rules, which are received by the department or are forwarded to the department by a county, following a county board of supervisors’ determination that a complainant’s allegation constitutes a violation, shall be investigated by the department if it is determined that the complaint is legally sufficient and an investigation is justified.
	65.209(1) If after evaluating a complaint to determine whether the allegation may constitute a violation, without investigating whether the facts supporting the allegation are true or untrue, the county board of supervisors shall forward its finding to the department director.
	65.209(2) A complaint is legally sufficient if it contains adequate information to investigate the complaint and if the allegation constitutes a violation, without an investigation of whether the facts supporting the allegation are true or untrue, of department rules, Iowa Code chapter 455B, 459, 459A, or 459B, or environmental standards in regulations subject to federal law and enforced by the department.
	65.209(3) The department in its discretion shall determine the urgency of the investigation, and the time and resources required to complete the investigation, based upon the circumstances of the case, including the severity of the threat to the quality of surface water or groundwater.
	65.209(4) The department shall notify the complainant and the alleged violator if an investigation is not conducted specifying the reason for the decision not to conduct an investigation.
	65.209(5) The department will notify the county board of supervisors where the violation is alleged to have occurred before doing a site investigation unless the department determines that a clear, present and impending danger to the public health or environment requires immediate action.
	65.209(6) The county board of supervisors may designate a county employee to accompany the department on the investigation of any site as a result of a complaint.
	65.209(7) A county employee accompanying the department on a site investigation has the same right of access to the site as the department official conducting the investigation during the period that the county designee accompanies the department official.

The department shall deliver a copy of the notice to the animal truck wash facility that is the subject of the complaint, any alleged violators if different from the animal truck wash facility and the county board of supervisors of the county where the violation is alleged to have occurred.
	65.209(9) When a person who is a department official, an agent of the department, or a person accompanying the department official or agent enters the premises of an animal truck wash, both of the following shall apply:
	a. 	The person may enter at any reasonable time in and upon any private or public property to investigate any actual or possible violation of Iowa Code chapter 455B, 459, 459A, or 459B or these rules. However, the owner or person in charge shall be notified.
	(1)	If the owner or occupant of any property refuses admittance to the animal truck wash facility, or if prior to such refusal the director demonstrates the necessity for a warrant, the director may make application under oath or affirmation to the district court of the county in which the property is located for the issuance of a search warrant.
	(2)	In the application, the director shall state that an inspection of the premises is mandated by the laws of this state or that a search of certain premises, areas, or things designated in the application may result in evidence tending to reveal the existence of violations of public health, safety, or welfare requirements imposed by statutes, rules or ordinances established by the state or a political subdivision thereof. The application shall describe the area, premises, or thing to be searched, give the date of the last inspection if known, give the date and time of the proposed inspection, declare the need for such inspection, recite that notice of desire to make an inspection has been given to affected persons and that admission was refused if that be the fact, and state that the inspection has no purpose other than to carry out the purpose of the statute, ordinance, or regulation pursuant to which inspection is to be made. If an item of property is sought by the director, it shall be identified in the application.
	(3)	If the court is satisfied from the examination of the applicant, and of other witnesses, if any, and of the allegations of the application of the existence of the grounds of the application, or that there is probable cause to believe their existence, the court may issue such search warrant.
	(4)	In making inspections and searches pursuant to the authority of this rule, the director must execute the warrant:
	1.	Within ten days after its date.
	2.	In a reasonable manner, and any property seized shall be treated in accordance with the provisions of Iowa Code chapters 808, 809, and 809A.

Open feedlot effluent removal is considered complete when the open feedlot effluent remaining in the runoff control system occupies less than 10 percent of the system’s design open feedlot effluent storage capacity.
During April, July and October, open feedlot effluent application operations shall be initiated on the first day that conditions are suitable for land application of open feedlot effluent, and application must continue on subsequent days that suitable conditions exist. If unfavorable weather conditions prevent complete application of open feedlot effluent to be accomplished during any of these months, open feedlot effluent application must be continued into the following month. Open feedlot effluent application operations may cease when complete application has been achieved.
Weather and soil conditions are normally considered suitable for land application of open feedlot effluent if:
- Land application areas are not frozen or snow-covered.
- Temperatures during application are greater than 32 degrees Fahrenheit.
- Precipitation has not exceeded  0.05 inch per day for each of the three days immediately preceding application and no precipitation is occurring on the day of application the water-holding capacity of the soil to accept the manure application without the possibility of runoff.
B.	No change.
	Item 77. Amend 567—Chapter 65, Appendix A, System 4, as follows:
SYSTEM 4: OPEN FEEDLOT EFFLUENT APPLICATION AFTER EACH
SIGNIFICANT PRECIPITATION EVENT
MAJOR SYSTEM FEATURES. No change.
DETAILED SYSTEM REQUIREMENTS:
Open Feedlot Effluent Control System. No change.
Open Feedlot Effluent Application Requirements: Open feedlot effluent must be removed from the open feedlot effluent control system and land-applied in accordance with the following requirements:
1.	No change.
2.	Feedlot Runoff Control System: Accumulated open feedlot effluent shall be removed from the feedlot runoff control system and disposed of by land application following each precipitation or snowmelt runoff event which results in significant open feedlot effluent accumulations in the control system. Open feedlot effluent accumulations will be considered significant whenever the available (unoccupied) storage capacity remaining in the control system is less than 90 percent of that required to store the runoff from the 25-year, 24-hour precipitation event.
Once the available storage capacity remaining in the open feedlot effluent control system is reduced to the point that open feedlot effluent application is necessary, open feedlot effluent application operations must be initiated on the first day that conditions are suitable for land application of open feedlot effluent, and application must continue on subsequent days that suitable conditions exist. Application operations may cease when the storage capacity available in the control system has been restored to greater than 90 percent of that required to store runoff from the 25-year, 24-hour precipitation event.
During application periods, land application shall be conducted at rates sufficient to ensure complete removal of accumulated open feedlot effluent from the control system in ten or fewer application days.
Weather and soil conditions are normally considered suitable for land application of open feedlot effluent if:
- Land application areas are not frozen or snow-covered.
- Temperatures during application are greater than 32 degrees Fahrenheit.
- Precipitation has not exceeded 0.05 inch per day for each of the three days immediately preceding application and no precipitation is occurring on the day of application the water-holding capacity of the soil to accept the manure application without the possibility of runoff.
	Item 78. Amend 567—Chapter 65, Appendix A, System 5, as follows:
SYSTEM 5: APRIL/MAY AND OCTOBER/NOVEMBER OPEN
FEEDLOT EFFLUENT APPLICATION
MAJOR SYSTEM FEATURES. No change.
DETAILED SYSTEM REQUIREMENTS:
Open Feedlot Effluent Control System. No change.
Open Feedlot Effluent Application Requirements: Open feedlot effluent must be removed from the open feedlot effluent control system and land-applied in accordance with the following requirements:
1.	No change.
2.	Feedlot Runoff Control System: At a minimum, accumulated open feedlot effluent shall be removed from the feedlot runoff control system and disposed of by land application during the periods April 1 through May 31 and October 1 through November 30.
During each of these periods, land application shall be conducted at rates sufficient to ensure complete removal of accumulated open feedlot effluent from the runoff control system in ten or fewer application days. Open feedlot effluent removal is considered complete when the open feedlot effluent remaining in the runoff control system occupies less than 10 percent of the system’s design open feedlot effluent storage capacity.
A feedlot operator may dispose of accumulated open feedlot effluent during any period of the year that conditions are suitable. While application during other periods will minimize the need for application during the April/May and October/November periods, the feedlot operator will still need to dispose of sufficient open feedlot effluent during these periods to reduce the open feedlot effluent volume remaining in the runoff control system during these periods to less than 10 percent of the system’s design open feedlot effluent storage capacity.
Land application of open feedlot effluent shall be conducted on days when weather and soil conditions are suitable. Weather and soil conditions are normally considered suitable for open feedlot effluent application if:
- Land application areas are not frozen or snow-covered.
- Temperatures during application are greater than 32 degrees Fahrenheit.
- Precipitation has not exceeded 0.05 inch per day for each of the three days immediately preceding application and no precipitation is occurring on the day of application the water-holding capacity of the soil to accept the manure application without the possibility of runoff.
