164.123—Emergency order.
        
        (a) 
         Whenever the Environmental Appeals Board determines that an emergency exists that does not permit him to hold a hearing before suspension, the Environmental Appeals Board may issue a suspension order in advance of notification to the registrant.
    
    
        
        (b) 
         The Environmental Appeals Board shall immediately notify the registrant of the suspension order. The registrant may then request a hearing in accordance with  §§ 164.121 and 164.122, but the suspension order shall remain in effect during the hearing pending the issuance of a final order on suspension.
