A producer or processor subject to degrade action for repeat violations must apply on an application provided by the department to have his or her dairy farm or milk processing plant regraded. The application must be signed by the producer or processor and must state that all violations, both repeat violations and nonrepeat violations, cited on the inspection that caused the degrade have been corrected. Within seven days after receiving a completed application for regrade, the department will reinspect the dairy farm or milk processing plant. If the department determines that all violations, both repeat violations and nonrepeat violations, cited on the inspection that caused the degrade have been corrected and the degrade period as determined by the director has ended, the department will regrade the dairy farm or milk processing plant operation.
