Administrator shall, pursuant to subsection (c) of this section, add to 
such list all substances that the Administrator determines have an ozone 
depletion potential of 0.2 or greater.

hydrochlorofluorocarbon-261 (HCFC-261)
hydrochlorofluorocarbon-262 (HCFC-262)
hydrochlorofluorocarbon-271 (HCFC-271)

The initial list under this subsection shall also include the isomers of 
the substances listed above. Pursuant to subsection (c) of this section, 
the Administrator shall add to the list of class II substances any other 
substance that the Administrator finds is known or may reasonably be 
anticipated to cause or contribute to harmful effects on the 
stratospheric ozone layer.

(c) Additions to the lists

    (1) The Administrator may add, by rule, in accordance with the 
criteria set forth in subsection (a) or (b) of this section, as the case 
may be, any substance to the list of class I or class II substances 
under subsection (a) or (b) of this section. For purposes of exchanges 
under section 7661f \1\ of this title, whenever a substance is added to 
the list of class I substances the Administrator shall, to the extent 
consistent with the Montreal Protocol, assign such substance to existing 
Group I, II, III, IV, or V or place such substance in a new Group.
---------------------------------------------------------------------------
    \1\ So in original. Probably should be section ``7671f''.
---------------------------------------------------------------------------
    (2) Periodically, but not less frequently than every 3 years after 
November 15, 1990, the Administrator shall list, by rule, as additional 
class I or class II substances those substances which the Administrator 
finds meet the criteria of subsection (a) or (b) of this section, as the 
case may be.
    (3) At any time, any person may petition the Administrator to add a 
substance to the list of class I or class II substances. Pursuant to the 
criteria set forth in subsection (a) or (b) of this section as the case 
may be, within 180 days after receiving such a petition, the 
Administrator shall either propose to add the substance to such list or 
publish an explanation of the petition denial. In any case where the 
Administrator proposes to add a substance to such list, the 
Administrator shall add, by rule, (or make a final determination not to 
add) such substance to such list within 1 year after receiving such 
petition. Any petition under this paragraph shall include a showing by 
the petitioner that there are data on the substance adequate to support 
the petition. If the Administrator determines that information on the 
substance is not sufficient to make a determination under this 
paragraph, the Administrator shall use any authority available to the 
Administrator, under any law administered by the Administrator, to 
acquire such information.
    (4) Only a class II substance which is added to the list of class I 
substances may be removed from the list of class II substances. No 
substance referred to in subsection (a) of this section, including 
methyl chloroform, may be removed from the list of class I substances.

(d) New listed substances

    In the case of any substance added to the list of class I or class 
II substances after publication of the initial list of such substances 
under this section, the Administrator may extend any schedule or 
compliance deadline contained in section 7671c or 7671d of this title to 
a later date than specified in such sections if such schedule or 
deadline is unattainable, considering when such substance is added to 
the list. No extension under this subsection may extend the date for 
termination of production of any class I substance to a date more than 7 
years after January 1 of the year after the year in which the substance 
is added to the list of class I substances. No extension under this 
subsection may extend the date for termination of production of any 
class II substance to a date more than 10 years after January 1 of the 
year after the year in which the substance is added to the list of class 
II substances.

(e) Ozone-depletion and global warming potential

    Simultaneously with publication of the lists under this section and 
simultaneously with any addition to either of such lists, the 
Administrator shall assign to each listed substance a numerical value 
representing the substance's ozone-depletion potential. In addition, the 
Administrator shall publish the chlorine and bromine loading potential 
and the atmospheric lifetime of each listed substance. One year after 
November 15, 1990 (one year after the addition of a substance to either 
of such lists in the case of a substance added after the publication of 
the initial lists of such substances), and after notice and opportunity 
for public comment, the Administrator shall publish the global warming 
potential of each listed substance. The preceding sentence shall not be 
construed to be the basis of any additional regulation under this 
chapter. In the case of the substances referred to in table 1, the 
ozone-depletion potential shall be as specified in table 1, unless the 
Administrator adjusts the substance's ozone-depletion potential based on 
criteria referred to in section 7671(10) of this title:
