Western States Petroleum Ass'n. v. Cal. Air Resources Bd.
Annotate this Case
The California Air Resources Board (CARB) adopted a regulation in August 2020 to limit emissions from ocean-going vessels while docked at California ports. The Western States Petroleum Association (WSPA) challenged this regulation, arguing that CARB acted arbitrarily and capriciously by setting unfeasible compliance deadlines for emissions control measures. WSPA also claimed that CARB violated the Administrative Procedures Act (APA) by not timely disclosing a commissioned report on tanker emissions and failed to adequately analyze safety hazards and cumulative environmental impacts under the California Environmental Quality Act (CEQA).
The Superior Court of Los Angeles County denied WSPA’s petition for a writ of mandate, finding that CARB had the authority to set emissions standards requiring future technology and that WSPA did not prove the necessary technology would not be developed in time. The court also found that CARB substantially complied with the APA’s notice provisions and did not violate CEQA in its environmental analysis.
The California Court of Appeal, Second Appellate District, affirmed the lower court’s decision. The appellate court held that CARB’s determination that compliance with the regulation was feasible did not lack evidentiary support. CARB relied on assurances from technology providers that capture and control systems could be adapted for tankers by the compliance deadlines. The court also found that CARB substantially complied with the APA by making the emissions report available before the end of the comment period, allowing WSPA to provide feedback. Finally, the court held that CARB’s environmental analysis under CEQA was adequate, as it provided a general discussion of potential impacts and appropriately deferred more specific analysis to future site-specific reviews.
