42 U.S.C. § 7671e — Accelerated schedule

(a) In general. EPA must, after notice and public comment, write regulations that set a faster phase-out and phase-down schedule than sections 7671c or 7671d require, for class I substances, class II substances, or the use of class II substances, if: (1) based on credible current scientific information — including any assessment under the Montreal Protocol — about a substance's harm to the stratospheric ozone layer, EPA decides a faster schedule may be needed to protect human health and the environment; (2) based on the availability of substitutes, EPA decides a faster schedule is practical, considering technology, safety, and other relevant factors; or (3) the Montreal Protocol itself is changed to require faster action on a substance. When deciding under (1) or (2), EPA must consider how much time is left under the current schedule. (b) Petition. Anyone may petition EPA to write these faster regulations. EPA must grant or deny the petition within 180 days of receiving it, and must publish an explanation if it denies the petition. If EPA grants the petition, it must finalize the new regulations within 1 year. Every petition must include enough data to support it. If EPA decides the available information isn't sufficient to decide, EPA must use whatever other legal authority it has to gather that information.
