Under SB1217, all facilities with 250 or more swine, 100 or more confined cattle, 75 or more horses, 1,000 or more sheep or 30,000 or more poultry with a liquid waste management system shall have a certified Operator in Charge (OIC). The operator is for the entire system so a certified operator is required on that date even if land application will not occur until some later date. A facility shall notify DWQ within 30 days after a new Operator in Charge is designated (see Appendix 11.1 A).

It has been advised by the Attorney General's Office that "animal operations not producing liquid residuals … are not required to designate a certified operator…" It has also been advised that "systems utilizing only nonstructural practices (for the management of animal waste) are exempt from the requirement to have a certified operator" (Appendix 11.1 B).
