An applicant must complete the spray irrigation seminar within three years of the exam date. Have at least three months experience as a Type V operator. Score at least 70% on the written exam. Inspectors must also have conducted ten (10) inspections at a Type V facility in the presence of a certified inspector.
Operators of a Type V facility have the option to be certified under the wastewater rules (Minn. Rules 9400) or the waste disposal rules (Minn. Rules 7048). If an operator is certified with a wastewater Class D or higher certification, the operator is not required to be certified as a Type V facility operator.
