Which of the following is NOT a requirement for a portable seed cleaner?

The answer choice indicating that a portable seed cleaner must be operated by certified personnel is the one that does not align with the established requirements. While there are regulations surrounding the operation and maintenance of portable seed cleaners, the requirement for them to be operated by certified personnel is not a standard stipulation.

In contrast, obtaining a permit from the commissioner, undergoing annual inspections, and reporting any losses within a specified timeframe are crucial regulatory measures designed to ensure the safe and effective operation of portable seed cleaning equipment. These requirements help to maintain industry standards, safeguard agricultural practices, and protect seed quality. The absence of a stipulation for certified personnel particularly emphasizes the focus on operational compliance through permits and inspections rather than mandating specific operator qualifications.
