Warehouse Working Group


In 2019, California Assembly Bill 423 (AB 423) amended the California Health and Safety Code which directed the District to consider adopting an indirect source rule to address pollution from mobile sources that is associated with stationary sources such as ports, warehouses, and distribution centers.  Per the AB 423 requirement, District staff researched potential indirect source rule concepts, met with stakeholders, and evaluated indirect sources such as ports, warehouses, and distribution centers located throughout San Diego County.  The District's Governing Board also directed staff to convene a working group of community and industry stakeholders to consider and develop potential alternative regulatory and non-regulatory strategies that could further reduce indirect source emissions at the community level.  The purpose of the Warehouse Working Group (WWG) was to offer input to the District regarding potential regulatory and non-regulatory strategies to reduce air pollution and public health impacts from heavy-duty trucks and other indirect sources associated with warehouses and distribution centers in the San Diego region, with priority to those facilities in under-resourced communities.  At its meeting on May 14, 2026, the San Diego County Air Pollution Control District Governing Board considered an item relating to indirect source emissions at Warehouses and Distribution Centers.  A recording of the meeting can be viewed here.



**At its April meeting, the San Diego County Air Pollution Control District Governing Board voted to continue the item regarding Strategies to Reduce Indirect Source Emissions at Warehouses and Distribution Centers.  The Board is scheduled to hear the continued item at a special meeting on May 14, 2026.  The public will have an opportunity to submit written and verbal comments at the May meeting.**
