This legislation aims to accelerate the environmental review and permitting process for data centers and their supporting infrastructure, defining "covered applications" for siting, constructing, expanding, or operating these facilities. A key provision states that civil actions challenging environmental reviews under various federal acts will not affect the validity of permits already issued for data centers. If a court finds an environmental review to be in violation, it must remand the matter to the relevant federal agency for resolution, rather than vacating the permit, and agencies must continue processing all covered applications during such litigation. To further expedite the process, the bill grants original and exclusive jurisdiction for judicial review of federal agency orders concerning these applications to the U.S. Courts of Appeals, which are instructed to provide expedited review . Additionally, a strict 90-day limitation is imposed for filing claims seeking judicial review of permits or approvals, starting from the publication of notice in the Federal Register.
