Sunshine State adopts warehousing heavy vehicle rule
On May 7, 2021, California’s South Coast Air Quality Management District (South Coast AQMD) adopted Rule 2305, also known as the Warehouse Indirect Source Rule (ISR). The ISR requires large warehouses (those 100,000 square feet and larger) to account for emissions from heavy-duty vehicles.
The rule requires each applicable facility to calculate Warehouse Actions and Investments to Reduce Emissions (WAIRE) points they must earn annually or pay mitigation fees to offset. WAIRE points depend in large part on the number of truck trips to a warehouse, data recordkeeping that is likely new to warehouse operators.
Immediate compliance actions
Affected warehouses and warehouse operators must take a few near-term actions, beginning with a Warehouse Operations Notification, required by all applicable operations. This initial notification deadline is no more than 60 days following rule adoption, July 6, 2021.
Truck trip records and reporting are being phased-in over a three-year period. However, for the largest group of warehouses, those with 250,000 square feet or more, data collection kicked in July 1, 2021. Initial and annual reporting obligations for those records begin in 2022. South Coast AQMD Rule 2305 requires that these truck trip records be collected by the warehouse using methods that meet specified criteria – including “verifiable” and “contemporaneously” (as they occur).
Purpose of the rule
Once fully phased in, South Coast AQMD estimates Rule 2305 will apply to more than 3,000 facilities and more than 4,000 operators of warehouses located within in the district. This new rule is intended to directly reduce nitrogen oxide (NOx) and diesel particulate matter (PM) emissions from heavy-duty trucks associated with warehousing operations. Emissions from sources associated with warehouses account for almost as many NOx emissions as all the refineries, power plants, and other stationary sources in the South Coast Air Basin combined. The agency says that reductions from this program and others like it are essential to meeting upcoming federal clean air standards.
