Recent guidance published by the California Air Resources Board (ARB) clarifies the treatment of diesel fuels under the Low Carbon Fuel Standard (LCFS) in light of the Court of Appeals’ May 30, 2017 decision in POET I. Meanwhile, in POET II, ARB recently filed a Motion for Judgment on the Pleadings (MJOP), in an attempt to have the lawsuit dismissed as moot before a hearing on the merits occurs. While the MJOP addresses all of the claims in POET II and various other filings have been made by the parties in connection with the motion (e.g., Requests for Judicial Notice, a Motion to Strike, etc.), this blog entry focuses only on the key aspects of the MJOP and POET’s opposition thereto.
New Guidance Regarding Implications of the POET I Decision
On November 22, 2017, the ARB posted regulatory guidance to clarify the scope of the writ of peremptory mandate issued by the Fresno County Superior Court on October 18, 2017 (the Modified Writ) to implement the May 30, 2017 POET I decision.
As we have discussed in previous posts, the POET I case arose from Petitioner POET, LLC’s challenges to the original LCFS regulation adopted by ARB in 2009. On April 10, 2017, the Court of Appeal ruled that ARB had failed to faithfully execute a writ of peremptory mandate requiring it to remedy violations of the California Environmental Quality Act (CEQA) that occurred during adoption of the original LCFS. In response to a petition for rehearing filed by ARB, the Court of Appeal reissued its opinion on May 30, 2017.

On May 13, 2019, the US Supreme Court denied certiorari in American Fuel & Petrochemical Manufacturers (AFPM), et al., v. O’Keeffe, et al (O’Keeffe), effectively affirming a US Court of Appeals for the Ninth Circuit decision that upheld the constitutionality of Oregon’s Clean Fuels Program (CFP). The CFP is modeled after, and operates according to, the same principles and general structure as California’s
substitute targets previously enacted by CARB in 2017 in connection with the POET I case. The Guidance becomes effective January 1, 2019 at which point the applicable diesel standards will revert to the schedule specified in the current
While California’s Cap-and-Trade Program attracts the lion’s share of attention in the trade press, CARB may view the LCFS as an equally important greenhouse gas (GHG) emissions reduction measure. According to CARB, the Cap-and-Trade Program’s traditional role in the state’s overarching scheme has been to backstop GHG reductions, not drive them. Under this interpretation, the Cap-and-Trade Program has acted as an insurance policy guaranteeing the state’s GHG emissions reduction trajectory via operation of the program’s hard cap in the event that other, more direct emissions reduction measures fail to achieve expected reductions (e.g., the Renewables Portfolio Standard, Advanced Clean Car Standards, Title 24 Energy Efficiency Standards, the LCFS, etc.).
