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 d. A field that is included in more than one manure 17 management plan or nutrient management plan as provided in 18 section 459A.208. If manure, including open feedlot effluent, 19 originating from more than one animal feeding operation is to 20 be applied to a field, the map shall indicate the months during 21 which the manure from that animal feeding operation is to be 22 applied to that field. 23 3. The manure management planning map shall be designed to 24 assist a person to apply manure in the most efficient practical 25 manner possible while reducing risks associated with runoff, 26 including by adjusting application rates and timing. 27 Sec. 2.

S.F. 2264 the manure management planning map as provided in section 1 459.311F prior to application. 2 EXPLANATION 3 The inclusion of this explanation does not constitute agreement with 4 the explanation’s substance by the members of the general assembly. 5 BACKGROUND. An animal feeding operation (AFO) is regulated 6 by the department of natural resources (DNR) under several Code 7 chapters, including Code chapter 459 governing all AFOs, which 8 includes provisions regulating confinement feeding operations, 9 and Code chapter 459A, which includes selected provisions 10 regulating open feedlot operations. An AFO is an area in 11 which agricultural animals are confined for 45 days or more 12 in any 12-month period, and all associated structures used 13 for the storage of manure. A confinement feeding operation 14 maintains animals in roofed buildings and stores liquid manure 15 in a formed or unformed structure (see Code section 459.102). 16 An open feedlot operation is an unroofed or partially roofed 17 facility without crop, vegetation, or forage growth or residue 18 cover (Code section 459A.102). Manure from an open feedlot 19 operation includes solids that may not be stored in a structure 20 (stockpiled). Open feedlot effluent refers to a combination of 21 manure, precipitation-induced runoff, or other runoff from an 22 open feedlot before its settleable solids have been removed. 23 Both Code chapters regulate the application of manure, often 24 pursuant to a plan required to be filed with DNR. In the 25 case of a confinement feeding operation, the plan is referred 26 to as a manure management plan (MMP) (Code section 459.312) 27 covering manure, including liquid manure, and in the case 28 of an open feedlot operation, the plan is referred to as a 29 nutrient management plan (NMP) (Code section 459A.208) covering 30 effluent. 31 BILL’S PROVISIONS. This bill requires DNR to prepare and 32 publish on its internet site a manure management planning 33 map (MMPM) to assist a person applying manure originating 34 from an AFO. The MMPM must be part of an interactive program 35 -2- LSB 6630XS (7) 91 da/js 2/ 3

S.F. 2264 in the form of a digital dynamic map that identifies areas 1 vulnerable to the application of manure based on a number of 2 factors determined by DNR. The factors must at least include 3 terrain and topography, the effect of climatic conditions, 4 and proximity to a designated area or a water source. A 5 designated area refers to a known sinkhole, a cistern, an 6 abandoned well, an unplugged agricultural drainage well, an 7 agricultural drainage well surface inlet, a drinking water 8 well, a designated wetland (designated as a protected wetland 9 by the United States department of the interior or DNR), or a 10 water source (a lake, river, reservoir, creek, stream, ditch, 11 or other body of water or channel having definite banks and a 12 bed with water flow). An MMPM must also identify fields that 13 are included in more than one MMP or NMP. A person completing 14 a manure management plan (in the case of a confinement feeding 15 operation) or nutrient management plan (in the case of an open 16 feedlot operation) must verify that the person consults with 17 the MMPM prior to application. 18 -3- LSB 6630XS (7) 91 da/js 3/ 3
