# §7671e. Accelerated schedule

- (a) **In general—** The [Administrator](/usc/42/7602.md?p=a) shall promulgate regulations, after notice and opportunity for public comment, which establish a schedule for phasing out the [production](/usc/42/7671.md?p=11) and [consumption](/usc/42/7671.md?p=6) of class I and [class II substances](/usc/42/7671.md?p=4) (or use of [class II substances](/usc/42/7671.md?p=4)) that is more stringent than set forth in section [7671c](/usc/42/7671c.md) or [7671d](/usc/42/7671d.md) of this title, or both, if—
  - (1) based on an assessment of credible current scientific information (including any assessment under the [Montreal Protocol](/usc/42/7671.md?p=9)) regarding harmful effects on the stratospheric ozone layer associated with a class I or [class II substance](/usc/42/7671.md?p=4), the [Administrator](/usc/42/7602.md?p=a) determines that such more stringent schedule may be necessary to protect human health and the environment against such effects,
  - (2) based on the availability of substitutes for listed substances, the [Administrator](/usc/42/7602.md?p=a) determines that such more stringent schedule is practicable, taking into account technological achievability, safety, and other relevant factors, or
  - (3) the [Montreal Protocol](/usc/42/7671.md?p=9) is [modified](/usc/42/7501.md?p=4) to include a schedule to control or reduce [production](/usc/42/7671.md?p=11), [consumption](/usc/42/7671.md?p=6), or use of any substance more rapidly than the applicable schedule under this subchapter.

  In making any determination under paragraphs [(1)](#a-1) and [(2)](#a-2), the [Administrator](/usc/42/7602.md?p=a) shall consider the status of the period remaining under the applicable schedule under this subchapter.

- (b) **Petition—** Any [person](/usc/42/7602.md?p=e) may petition the [Administrator](/usc/42/7602.md?p=a) to promulgate regulations under this section. The [Administrator](/usc/42/7602.md?p=a) shall grant or deny the petition within 180 days after receipt of any such petition. If the [Administrator](/usc/42/7602.md?p=a) denies the petition, the [Administrator](/usc/42/7602.md?p=a) shall publish an explanation of why the petition was denied. If the [Administrator](/usc/42/7602.md?p=a) grants such petition, such final regulations shall be promulgated within 1 year. Any petition under this subsection shall include a showing by the petitioner that there are data adequate to support the petition. If the [Administrator](/usc/42/7602.md?p=a) determines that information is not sufficient to make a determination under this subsection, the [Administrator](/usc/42/7602.md?p=a) shall use any authority available to the [Administrator](/usc/42/7602.md?p=a), under any law administered by the [Administrator](/usc/42/7602.md?p=a), to acquire such information.
