In an opinion filed August 27 and later ordered published on September 24, 2024, the Fifth District Court of Appeal affirmed a judgment denying a writ petition that challenged the State Air Resources Board’s (CARB) adoption of the Advanced Clean Trucks Regulation (Regulation) on CEQA and Administrative Procedures Act (APA; Gov. Code, § 11340 et seq) grounds.  California Natural Gas Vehicle Coalition v. State Air Resources Board (2024) 105 Cal.App.5th 304.  The Court held that CARB’s in-depth study of three alternatives (including the “no project” alternative) constituted a reasonable range for CEQA purposes; it further held that CARB’s alternative analysis wasn’t deficient for rejecting without in-depth study, as infeasible for policy reasons, an alternative proposed by opponents of the Regulation that would have applied a low-NOx vehicle credit to sales mandates applicable to zero-emission vehicles (ZEV).  Based on the same reasoning, the Court held CARB also need not have considered the now-NOx vehicle credit as a mitigation measure for the acknowledged significant near-term air quality impacts of the Regulation.  (The Court also rejected appellant Coalition’s APA arguments in a portion of its opinion that won’t be further discussed in this post.)  Finally, the Court held on CARB’s affirmative appeal that any error with respect to the admission of a specific “white paper” document into the administrative record was nonprejudicial, and therefore harmless, as it did not impact either the trial court’s or its own analysis.
