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.
