A district court has ruled that federal law does not preempt an indirect source rule that targets emissions associated with warehouses in Southern California.

On December 14, 2023, a US federal judge rejected claims that federal law preempts the South Coast Air Quality Management District’s (SCAQMD or the District) adoption of Rule 2305 (Rule), upholding the first-in-the-nation Rule[1] that regulates trucking emissions from warehouses.

Rule 2305 is the Warehouse Indirect Source Rule (ISR) — Warehouse Actions and Investments to Reduce Emissions (WAIRE) Program. As described in this Latham blog post, the WAIRE Program applies to certain warehouses in the South Coast Air Basin and imposes a compliance obligation based on the number of truck visits to that warehouse per year. Warehouse operators can meet that obligation by taking any number of emissions-reducing actions, either from the “WAIRE Menu” or through a custom plan approved by the District.

Regulators are pursuing steep fines in response to widespread alleged noncompliance with an emissions rule still subject to potential reversal by the courts.

Key Points:

  • The enforcement action alleges 1,400 warehouses are noncompliant.
  • Noncompliance can result in fines of up to $11,710 per day.
  • Litigation challenging this program remains pending, with no quick end in sight.

On September 20, 2023, the South Coast Air Quality Management District (SCAQMD or the District) announced an enforcement initiative for Rule 2305, also known as the Warehouse Indirect Source Rule (ISR), which is part of the Warehouse Actions and Investments to Reduce Emissions (WAIRE) Program. As described in this June 2021 blog post, the WAIRE Program applies to warehouses in the South Coast Air Basin over 100,000 square feet, with a phased implementation based on warehouse size. The ISR imposes a compliance obligation based on the number of truck visits to that warehouse per year, which warehouse operators can meet through emissions-reducing actions, either from the “WAIRE Menu” or through a custom plan approved by the District.

The State and eNGOs seek to defend an emissions rule that trucking and airline trade groups are challenging in federal court.

On October 13, 2021, the State of California, on behalf of the Office of the Attorney General and the California Air Resources Board (CARB, and together, the State), filed a motion to intervene in a federal lawsuit challenging the South Coast Air Quality Management District (SCAQMD or the District) adoption of Rule 2305. Rule 2305 is the Warehouse Indirect Source Rule (ISR) – Warehouse Actions and Investments to Reduce Emissions (WAIRE) Program. Plaintiff, the California Trucking Association (CTA), filed a complaint in the US District Court for the Central District of California on August 5, 2021, to which the District filed an answer on October 7, 2021.[i] In addition to the State, Airlines for America filed a motion to intervene as a proposed plaintiff, while a group of environmental NGOs seek to intervene as proposed defendants. Each proposed intervenor is discussed further below.

A local air district approved a rule requiring warehouses to adopt clean technologies or pay a mitigation fee.

At a contentious board hearing on May 7, 2021, the South Coast Air Quality Management District (SCAQMD) approved a first-in-the-nation rule to regulate trucking emissions from warehouses by a 9-4 vote. Rule 2305, the Warehouse Indirect Source Rule (ISR), establishes the Warehouse Actions and Investments to Reduce Emissions (WAIRE) Program to reduce emissions associated with warehouse activity. The WAIRE Program essentially requires warehouse operators to take actions to electrify warehouse activities and the trucks that visit warehouses in order to reduce nitrogen oxides (NOx) and diesel particulate matter (DPM) emissions. As previewed in a 2019 Latham blog post, despite the warehouse sector’s limited control over the types of trucks servicing its facilities (warehouses generally do not own or operate trucking fleets), the ISR imposes obligations on warehouses to indirectly reduce trucking emissions. The WAIRE Program applies to warehouses with more than 100,000 square feet of warehouse space in a single building, and will phase in over three years based on warehouse size, with the largest warehouses (i.e., more than 250,000 square feet) having the earliest compliance period.
