Two years ago the South Coast Air Quality Management District (“SCAQMD”) adopted its Warehouse Indirect Source Rule – Rule 2305. SCAQMD regulates air quality in areas of Los Angeles, Orange, Riverside, and San Bernardina counties. The rule requires warehouse operators to account for truck trips to and from their facilities and mitigate the resulting diesel exhaust emissions, including by paying a mitigation fee to the SCQAMD. For a more detailed discussion of its requirements see my article about the proposed rule here.
On July 19, 2023, the Center for Community Action and Environmental Justice (“CCAEJ”), an environmental justice organization from Riverside County, filed a lawsuit in federal court against the United States Environmental Protection Agency (“US EPA”) to compel the US EPA to approve Rule 2305.
The lawsuit signals CCAEJ’s intent to make Rule 2305 enforceable by citizen suits under the federal Clean Air Act. Section 304 of the Clean Air Act allows any person to file a citizen’s lawsuit in federal court against any person alleged to be in violation of the Clean Air Act or of any rule or permit issued under the authority of the Clean Air Act. Presently, Rule 2305 is enforceable only by the SCAQMD. If the US EPA approves the rule as part of California’s state implementation plan, however, anyone affected by a warehouse facility’s indirect diesel exhaust emissions will be able to file a federal lawsuit to enforce the rule.
Meanwhile, the SCAQMD will be holding a public meeting on July 27 to discuss how it will make each warehouse’s compliance data publicly accessible on the SCAQMD website.
These developments foretell future enforcement lawsuits by local warehouse opponents. Warehouse owners and operators should take note and confirm their compliance with Rule 2305.
