A local air district is developing a rule that would require both existing and proposed warehouses to reduce trucking emissions or pay a mitigation fee.

The South Coast Air Quality Management District (SCAQMD or District) is developing a so-called Indirect Source Rule (ISR) that would require Southern California warehouses to reduce emissions associated with trucking activity and on-site equipment. Proposed Rule 2305, recently released by the District in discussion draft form, would establish the Warehouse Actions and Investments to Reduce Emissions (WAIRE) Program — which would apply to owners and operators of warehouses located in the South Coast Air Basin (Basin) with greater than 100,000 square feet of indoor space in a single building. If the SCAQMD’s development timeline holds, Proposed Rule 2305 will phase in on July 1, 2020.
