A. Any hydrologic connection between wastewater and waters of the state outside that authorized by the provisions of the Oklahoma Concentrated Animal Feeding Operations Act shall constitute a discharge to waters of the state.

B. Site-specific conditions shall be considered in the design and construction of liners. Liners for retention structures shall be designed and constructed in accordance with the provisions of this section and generally accepted engineering practices established by rules of the Board or as required by the federal Environmental Protection Agency. Liners for lagoons owned or operated by an animal feeding operation with less than one thousand (1,000) animal units may be designed and constructed pursuant to Technical Note 716 of the United States Department of Agriculture Natural Resources Conservation Service or its current equivalent so long as the facility is designed by the United States Department of Agriculture Natural Resources Conservation Service.

D. All substances entering the retention structures shall be composed entirely of wastewaters from the proper operation and maintenance of an animal feeding operation and the runoff from the animal feeding operation area. The disposal of any materials, other than substances associated with proper operation and maintenance of the facility into the containment structures, including but not limited to human waste, is prohibited.

E. Documentation, sampling data, and any other records required by this section shall be maintained on site for as long as the facility is in operation. Samples collected during the first year of the retention structure may be considered the baseline data and shall be retained on site as long as the facility is in operation. Baseline data for the facility shall be determined based on the best information available.
