A. All irrigation systems into which any swine waste will be injected shall be equipped with one or both of the following systems:
1. An antipollution system, approved by the State Board of Agriculture, capable of preventing the backflow of swine waste into the groundwater. The system shall include a safety check valve with a removable inspection port, anti-syphon vent, and low-pressure escape drain. An interlock device shall be installed on pumps that pump the swine waste so that if a fresh water irrigation pump shuts down, the pump that pumps the swine waste will also immediately shut down, preventing the chance of leakage past the check valve; or
2. A system which provides for a complete and total disconnection between the flow of fresh water and the flow of swine waste. The system shall be capable of a manual disconnection between fresh water and the swine waste.
B. The Oklahoma Department of Agriculture, Food, and Forestry shall make annual on-site inspections examining the operative status of the check valves and interlock devices.
C. The operator of the irrigation system shall be responsible to ensure:
1. That the valves and interlock devices remain operative between annual inspections by the Department; or
2. Complete disconnection from fresh water when introducing swine waste into the system.
