class II substance under title VI; 
‘‘(ii) the Administrator has determined 
that 1 metric ton of such gas does not make 
a contribution to global warming that is 
equal to or greater than that made by 1 
metric ton of carbon dioxide; or 
‘‘(iii) the person manufacturing or im-
porting the gas for distribution into inter-

submitted to the Administrator, at least 90 
days before the start of such manufacture, 
introduction into commerce, or emission, a 
notice of such person’s manufacture, intro-
duction into commerce, or emission of such 
gas, and the Administrator has not deter-
