§ 2-20-51 — Irrigation systems.

A. All irrigation systems into which any animal 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 animal 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 animal waste so that if a fresh water irrigation pump shuts down, the pump that pumps the animal 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 animal waste. The system shall be capable of a manual disconnection between fresh water and the animal 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 Oklahoma Department of Agriculture, Food, and Forestry; or 2. Complete disconnection from fresh water when introducing animal waste into the system.
