As a new employee do I need to be within sight and sound of a certified commercial service representative?

Question: 

As a new employee or commercial manure service representative working for a commercial manure service, I understand I can work for the first 30 days of my initial employment without being certified. Please explain the requirement for supervision. Do I need to be within sight and sound of a certified commercial service representative? Do they need to be present?

Answer: 

New employees of a commercial manure service who are not yet certified can apply manure for the first 30 days of employment after they are hired, if they are supervised by a certified commercial manure applicator. The law requires a certified representative to be within sight or immediate communication distance of the uncertified person. The certified representative must be physically present at the manure application site and supervising the uncertified person who is applying manure. The uncertified representative must also be actively seeking certification. After 30 days, the new employees must meet certification requirements. This 30 day exemption is only valid once and does not apply each time the employee is rehired.
