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.
(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:
