28 CFR §51.34

1. (a)When a submitting authority is required under State law or local ordinance or otherwise finds it necessary to implement a change within the 60-day period following submission, it may request that the submission be given expedited consideration. The submission should explain why such consideration is needed and provide the date by which a determination is required.
2. (b)Jurisdictions should endeavor to plan for changes in advance so that expedited consideration will not be required and should not routinely request such consideration. When a submitting authority demonstrates good cause for expedited consideration the Attorney General will attempt to make a decision by the date requested. However, the Attorney General cannot guarantee that such consideration can be given.
3. (c)Notice of the request for expedited consideration will be given to interested parties registered under § 51.32.
