All irrigation systems into which any swine waste will be\n\ninjected shall be equipped with one or both of the following\n\nsystems:\n\n1. An antipollution system, approved by the State Board of\n\nAgriculture, capable of preventing the backflow of swine waste into\n\nthe groundwater. The system shall include a safety check valve with\n\na removable inspection port, anti-syphon vent, and low-pressure\n\nescape drain. An interlock device shall be installed on pumps that\n\npump the swine waste so that if a fresh water irrigation pump shuts\n\ndown, the pump that pumps the swine waste will also immediately shut\n\ndown, preventing the chance of leakage past the check valve; or\n\n2. A system which provides for a complete and total\n\ndisconnection between the flow of fresh water and the flow of swine\n\nwaste. The system shall be capable of a manual disconnection\n\nbetween fresh water and the swine waste.\n\nB. The Oklahoma Department of Agriculture, Food, and Forestry\n\nshall make annual on-site inspections examining the operative status\n\nof the check valves and interlock devices.\n\nC. The operator of the irrigation system shall be responsible\n\nto ensure:\n\n1. That the valves and interlock devices remain operative\n\nbetween annual inspections by the Department; or\n\n2. Complete disconnection from fresh water when introducing\n\nswine waste into the system.","path":["OK Code","Title 2"],"source_url":"https://www.oklegislature.gov/OK_Statutes/CompleteTitles/os2.pdf","current_through":"2026-08-14","vintage":"open-us-law v2026.08, retrieved 2026-09-14","retrieved_at":"2026-09-14T18:32:36Z","sha256":"6171e11a8d93d2b4572a7ac49b75d3261598fd5e4af1648b4d10345d611e25fd","source_id":"us-ok","stale":false,"prev":"us-ok/okla.-stat.-tit.-2-2-20-12","next":"us-ok/okla.-stat.-tit.-2-2-20-14"},"notice":"GroundRules: Original legal text.
