Step-by-step explanation:
When the Department's investigator issues a Notice of Deficiencies for a minor violation, the licensees should take immediate action to address the deficiencies. They should carefully review the notice and identify the specific areas that need improvement, and then take appropriate steps to rectify the identified deficiencies. This may involve conducting internal investigations, implementing corrective measures, and providing evidence of compliance to the Department, if required.
