Animal feeding operations licensed pursuant to the\n\nprovisions of the Oklahoma Concentrated Animal Feeding Operations\n\nAct shall utilize Best Management Practices, or may substitute for\n\nbest management practice equivalent measures contained in a site-\n\nspecific Animal Waste Management Plan meeting the conditions and\n\nrequirements established by subsection C of this section and by\n\nrules promulgated by the Board pursuant to the Oklahoma Concentrated\n\nAnimal Feeding Operations Act.\n\nB. The criteria for Best Management Practices shall be\n\npromulgated by rule by the Board, based upon existing physical and\n\neconomic conditions, opportunities and constraints and shall\n\ninclude, but not be limited to, the following:\n\n1. There shall be no discharge of process wastewater to waters\n\nof the state except in accordance with the provisions of the\n\nOklahoma Concentrated Animal Feeding Operations Act;\n\n2. Animal waste shall be isolated from outside surface drainage\n\nby ditches, dikes, berms, terraces or other such structures except\n\nfor a twenty-five-year, twenty-four-hour rainfall event;\n\n3. No waters of the state shall come into direct contact with\n\nthe animals confined on the animal feeding operation;\n\n4. Animal waste handling, treatment, management and removal\n\nshall:\n\na. not create an environmental or a public health hazard,\n\nb. not result in the contamination of public or private\n\ndrinking water supplies,\n\nc. conform with Oklahoma Water Quality Standards,\n\nd. not violate any state or federal laws relating to\n\nendangered or threatened species of plant, fish or\n\nwildlife or to migratory birds,\n\ne. conform to such other handling, treatment and\n\nmanagement and removal requirements deemed necessary\n\nby the Oklahoma Department of Agriculture, Food, and\n\nForestry to implement the Oklahoma Concentrated Animal\n\nFeeding Operations Act and rules promulgated pursuant\n\nthereto, and\n\nf. ensure that watersheds and groundwater are adequately\n\nprotected;\n\n5. If, for any reason, there is a discharge other than a spill\n\nof less than one hundred (100) gallons, the licensee is required to\n\nmake immediate notification to the Department. The report of the\n\ndischarge shall include:\n\na. a description and cause of the discharge, including a\n\ndescription of the flow path to the receiving water\n\nbody,\n\nb. an estimation of the flow rate and volume discharged,\n\nc. the period of discharge, including exact dates and\n\ntimes, and if not already corrected, the anticipated\n\ntime the discharge is expected to continue,\n\nd. steps taken to reduce, eliminate and prevent\n\nrecurrence of the discharge, and\n\ne. test results for fecal coliform bacteria, five-day\n\nbiochemical oxygen demand (BOD5), total suspended\n\nsolids (TSS), ammonia nitrogen, total Kjeldahl\n\nnitrogen (TKN), any pesticides which the operator has\n\nreason to believe could be in the discharge, or other\n\nparameters as required by the Department which the\n\nDepartment has reason to believe could be in the\n\ndischarge;\n\n6. Notwithstanding the provisions of paragraph 5 of this\n\nsubsection, any spill that leaves the property owned or controlled\n\nby the licensee shall be reported to the Department regardless of\n\ntotal number of gallons spilled; and\n\n7. The Department shall maintain records of all discharges and\n\nshall separately maintain records of all spills.\n\nC. The Animal Waste Management Plan shall include at a minimum:\n\n1. Animal waste removal procedures;\n\n2. Records of inspections of retention structures, including,\n\nbut not limited to, specific measurement of wastewater level;\n\n3. All calculations in determining land application rates,\n\nacreage and crops for the land application rate of both solid and\n\nliquid animal wastes on land owned or controlled by the licensee;\n\n4. Requirements including that:\n\na. (1) land application of animal waste shall not exceed\n\nthe nitrogen uptake of the crop coverage or\n\nplanned crop planting with any land application\nof wastewater level;\n\n3. All calculations in determining land application rates,\n\nacreage and crops for the land application rate of both solid and\n\nliquid animal wastes on land owned or controlled by the licensee;\n\n4. Requirements including that:\n\na. (1) land application of animal waste shall not exceed\n\nthe nitrogen uptake of the crop coverage or\n\nplanned crop planting with any land application\n\nof wastewater or manure. Where local water\n\nquality is threatened by phosphorous, in no case\n\nshall the applicant or licensee exceed the\n\napplication rates in the most current Natural\n\nResources Conservation Service publication titled\n\nWaste Utilization Standard, and\n\n(2) timing and rate of applications shall be in\n\nresponse to crop needs, expected precipitation\n\nand soil conditions,\n\nb. land application practices shall be managed so as to\n\nreduce or minimize:\n\n(1) the discharge of process water or animal waste to\n\nwaters of the state,\n\n(2) contamination of waters of the state, and\n\n(3) odor,\n\nc. facilities including waste retention structures, waste\n\nstorage sites, ponds, pipes, ditches, pumps, and\n\ndiversion and irrigation equipment shall be maintained\n\nto ensure ability to fully comply with the terms of\n\nthe Oklahoma Concentrated Animal Feeding Operations\n\nAct, and\n\nd. adequate equipment and land application area shall be\n\navailable for removal of such waste and wastewater as\n\nrequired to maintain the proper operating volume of\n\nthe retention structure; and\n\n5. Such other information deemed necessary by the Department to\n\nadminister the provisions of the Oklahoma Concentrated Animal\n\nFeeding Operations Act and rules promulgated pursuant thereto.\n\nD. Records shall be maintained of all animal wastes applied on\n\nland owned or controlled by the licensee, and sold or given to other\n\npersons for disposal.\n\nE. Soils in areas in which animal waste is applied shall be\n\nanalyzed, annually, for phosphates, nitrates and soil pH prior to\n\nthe first application of the animal waste in the calendar year. A\n\ncopy of the results of the analysis shall be submitted to the\n\nDepartment upon request by the Department. Such analysis shall be\n\nretained by the animal feeding operation as long as the facility is\n\nin operation.\n\nF. Every animal feeding operation licensed pursuant to the\n\nprovisions of Oklahoma Concentrated Animal Feeding Operations Act\n\nshall develop a plan approved by the Department for the disposal of\n\ncarcasses associated with normal mortality.\n\n1. Dead animals shall be disposed of in accordance with a\n\ncarcass disposal plan developed by the applicant or licensee and\n\napproved by the Department.\n\n2. The plan shall include provisions for the disposal of\n\ncarcasses associated with normal mortality, with emergency disposal\n\nwhen a major disease outbreak or other emergency results in deaths\n\nsignificantly higher than normal mortality rates and other\n\nprovisions which will provide for a decrease in the possibility of\n\nthe spread of disease and prevent the contamination of waters of the\n\nstate.
