H.F. 2445 Section 1. NEW SECTION . 459.311F Manure management planning 1 map. 2 1. The department shall prepare and publish on its internet 3 site a manure management planning map to assist a person 4 applying manure originating from an animal feeding operation. 5 2. The manure management planning map shall be part of an 6 interactive computer program. The map shall be in the form of 7 a digital dynamic map that incorporates geographic information 8 system technology in a manner that allows a user to immediately 9 identify areas that are vulnerable to pollution caused by 10 manure application due to one or more factors identified by the 11 department, including but not limited to any of the following: 12 a. Terrain, including karst terrain, and topography. 13 b. The effect of climatic conditions. 14 c. The proximity to a designated area or a water source, 15 including a high-quality water resource. 16 3. The manure management planning map shall be designed to 17 assist a person to apply manure in the most efficient practical 18 manner possible while reducing risks associated with runoff, 19 including by adjusting application rates and timing. 20 Sec. 2. Section 459.312, subsection 10, Code 2026, is 21 amended by adding the following new paragraph: 22 NEW PARAGRAPH . 0c. A verification that the person consults 23 the manure management planning map as provided in section 24 459.311F prior to application. 25 Sec. 3. Section 459A.208, subsection 7, Code 2026, is 26 amended by adding the following new paragraph: 27 NEW PARAGRAPH . 0c. A verification that the person consults 28 the manure management planning map as provided in section 29 459.311F prior to application. 30 EXPLANATION 31 The inclusion of this explanation does not constitute agreement with 32 the explanation’s substance by the members of the general assembly. 33 BACKGROUND. An animal feeding operation (AFO) is regulated 34 by the department of natural resources (DNR) under several Code 35 -1- LSB 6630YH (2) 91 da/js 1/ 3

H.F. 2445 chapters, including Code chapter 459 governing all AFOs, which 1 includes provisions regulating confinement feeding operations, 2 and Code chapter 459A, which includes selected provisions 3 regulating open feedlot operations. An AFO is an area in 4 which agricultural animals are confined for 45 days or more 5 in any 12-month period, and all associated structures used 6 for the storage of manure. A confinement feeding operation 7 maintains animals in roofed buildings and stores liquid manure 8 in a formed or unformed structure (see Code section 459.102). 9 An open feedlot operation is an unroofed or partially roofed 10 facility without crop, vegetation, or forage growth or residue 11 cover (Code section 459A.102). Manure from an open feedlot 12 operation includes solids that are usually not stored in a 13 structure. Both Code chapters regulate the application of 14 manure, often pursuant to a plan required to be filed with 15 DNR. In the case of a confinement feeding operation, the plan 16 is referred to as a manure management plan (MMP) (Code section 17 459.313) and in the case of an open feedlot operation, the 18 plan is referred to as a nutrient management plan (NMP) (Code 19 section 459A.208). 20 BILL’S PROVISIONS. This bill requires DNR to prepare and 21 publish on its internet site a manure management planning 22 map (MMPM) to assist a person applying manure originating 23 from an animal feeding operation. The MMPM must be part of 24 an interactive program in the form of a digital dynamic map 25 that identifies areas vulnerable to the application of manure 26 based on a number of factors determined by DNR. The factors 27 must at least include terrain and topography, the effect of 28 climatic conditions, and proximity to a designated area or a 29 water source. A designated area refers to a known sinkhole, 30 a cistern, an abandoned well, an unplugged agricultural 31 drainage well, an agricultural drainage well surface inlet, 32 a drinking water well, a designated wetland (designated as 33 a protected wetland by the United States department of the 34 interior or DNR), or a water source (a lake, river, reservoir, 35 -2- LSB 6630YH (2) 91 da/js 2/ 3

H.F. 2445 creek, stream, ditch, or other body of water or channel having 1 definite banks and a bed with water flow). A person completing 2 an MMP (in the case of a confinement feeding operation) or NMP 3 (in the case of an open feedlot operation) must verify that the 4 person consults with the MMPM prior to application. 5 -3- LSB 6630YH (2) 91 da/js 3/ 3
