250.144—How do I designate a new operator when a designation of operator terminates?
        
        (a) 
         When a Designation of Operator terminates, the Regional Supervisor must approve a new designated operator before you may continue operations. Each lessee must submit a new executed Designation of Operator form.
    
    
        
        (b) 
         If your Designation of Operator is terminated, or a controversy develops between you and your designated operator, you and your designated operator must protect the lessor's interests.
