United States may engage  in transfers with other Parties  to the
Protocol under the following conditions:
       (1) The  United States may transfer  production allowances
     to  another  Party if,  at the  time  of such  transfer, the
     Administrator  establishes revised production limits for the
     United States such that the aggregate national United States
     production permitted  under  the revised  production  limits
     equals  the  lesser  of  (A) the  maximum  production  level
     permitted for  the substance or substances  concerned in the
     transfer  year  under  the  Protocol  minus  the  production
     allowances  transferred,  (B) the  maximum  production level
     permitted for  the substance or substances  concerned in the
     transfer  year  under  applicable  domestic  law  minus  the
     production allowances transferred, or (C) the average of the

     substances concerned for  the 3 years prior to  the transfer
     minus the production allowances transferred.
       (2) The  United States may  acquire production  allowances
     from another Party  if, at  the time of  such transfer,  the
     Administrator  finds that  the other  Party has  revised its
     domestic production  limits in  the same manner  as provided
     with respect to transfers by the United States in subsection
     (a).
