2023 Oklahoma Statutes › Title 2. Agriculture › §2-20-48. Best Management Practices - Animal Waste Management Plans.

A. Animal feeding operations licensed pursuant to the provisions of the Oklahoma Concentrated Animal Feeding Operations Act shall utilize Best Management Practices, or may substitute for best management practice equivalent measures contained in a site-specific Animal Waste Management Plan meeting the conditions and requirements established by subsection C of this section and by rules promulgated by the Board pursuant to the Oklahoma Concentrated Animal Feeding Operations Act.
B. The criteria for Best Management Practices shall be promulgated by rule by the Board, based upon existing physical and economic conditions, opportunities and constraints and shall include, but not be limited to, the following:
1. There shall be no discharge of process wastewater to waters of the state except in accordance with the provisions of the Oklahoma Concentrated Animal Feeding Operations Act;
2. Animal waste shall be isolated from outside surface drainage by ditches, dikes, berms, terraces or other such structures except for a twenty-five-year, twenty-four-hour rainfall event;
3. No waters of the state shall come into direct contact with the animals confined on the animal feeding operation;
4. Animal waste handling, treatment, management and removal shall:
a.
not create an environmental or a public health hazard,
b.
not result in the contamination of public or private drinking water supplies,
c.
conform with Oklahoma Water Quality Standards,
d.
not violate any state or federal laws relating to endangered or threatened species of plant, fish or wildlife or to migratory birds,
e.
conform to such other handling, treatment and management and removal requirements deemed necessary by the Oklahoma Department of Agriculture, Food, and Forestry to implement the Oklahoma Concentrated Animal Feeding Operations Act and rules promulgated pursuant thereto, and
f.
ensure that watersheds and groundwater are adequately protected;
5. If, for any reason, there is a discharge other than a spill of less than one hundred (100) gallons, the licensee is required to make immediate notification to the Department. The report of the discharge shall include:
a.
a description and cause of the discharge, including a description of the flow path to the receiving water body,
b.
an estimation of the flow rate and volume discharged,
c.
the period of discharge, including exact dates and times, and if not already corrected, the anticipated time the discharge is expected to continue,
d.
steps taken to reduce, eliminate and prevent recurrence of the discharge, and
e.
test results for fecal coliform bacteria, five-day biochemical oxygen demand (BOD5), total suspended solids (TSS), ammonia nitrogen, total Kjeldahl nitrogen (TKN), any pesticides which the operator has reason to believe could be in the discharge, or other parameters as required by the Department which the Department has reason to believe could be in the discharge;
6. Notwithstanding the provisions of paragraph 5 of this subsection, any spill that leaves the property owned or controlled by the licensee shall be reported to the Department regardless of total number of gallons spilled; and
7. The Department shall maintain records of all discharges and shall separately maintain records of all spills.
C. The Animal Waste Management Plan shall include at a minimum:
1. Animal waste removal procedures;
2. Records of inspections of retention structures, including, but not limited to, specific measurement of wastewater level;
3. All calculations in determining land application rates, acreage and crops for the land application rate of both solid and liquid animal wastes on land owned or controlled by the licensee;
4. Requirements including that:
a.
(1)
land application of animal waste shall not exceed the nitrogen uptake of the crop coverage or planned crop planting with any land application of wastewater or manure. Where local water quality is threatened by phosphorous, in no case shall the applicant or licensee exceed the application rates in the most current Natural Resources Conservation Service publication titled Waste Utilization Standard, and
(2)
timing and rate of applications shall be in response to crop needs, expected precipitation and soil conditions,
b.
land application practices shall be managed so as to reduce or minimize:
(1)
the discharge of process water or animal waste to waters of the state,
(2)
contamination of waters of the state, and
(3)
odor,
c.
facilities including waste retention structures, waste storage sites, ponds, pipes, ditches, pumps, and diversion and irrigation equipment shall be maintained to ensure ability to fully comply with the terms of the Oklahoma Concentrated Animal Feeding Operations Act, and
d.
adequate equipment and land application area shall be available for removal of such waste and wastewater as required to maintain the proper operating volume of the retention structure; and
5. Such other information deemed necessary by the Department to administer the provisions of the Oklahoma Concentrated Animal Feeding Operations Act and rules promulgated pursuant thereto.
D. Records shall be maintained of all animal wastes applied on land owned or controlled by the licensee, and sold or given to other persons for disposal.
E. Soils in areas in which animal waste is applied shall be analyzed, annually, for phosphates, nitrates and soil pH prior to the first application of the animal waste in the calendar year. A copy of the results of the analysis shall be submitted to the Department upon request by the Department. Such analysis shall be retained by the animal feeding operation as long as the facility is in operation.
F. Every animal feeding operation licensed pursuant to the provisions of Oklahoma Concentrated Animal Feeding Operations Act shall develop a plan approved by the Department for the disposal of carcasses associated with normal mortality.
1. Dead animals shall be disposed of in accordance with a carcass disposal plan developed by the applicant or licensee and approved by the Department.
2. The plan shall include provisions for the disposal of carcasses associated with normal mortality, with emergency disposal when a major disease outbreak or other emergency results in deaths significantly higher than normal mortality rates and other provisions which will provide for a decrease in the possibility of the spread of disease and prevent the contamination of waters of the state. The plan shall comply with rules promulgated by the Department.
