South Coast Air Quality Management District Warehouse Indirect Source Rule (WAIRE)

South Coast Air Quality Management District’s (AQMD) Warehouse Indirect Source Rule 2305 (WAIRE) is a compliance program for larger warehouses within South Coast AQMD’s jurisdictions – including Los Angeles, Orange, San Bernardino, and Riverside counties. The program is designed to mitigate emissions produced by heavy and medium-duty traffic that services the warehouses within the district through warehouse operators’ participation in WAIRE.  

GNA can help warehouse operators understand their obligations under this rule and how best to meet those obligations in a cost-effective manner. 

Notice! South Coast AQMD’s first reporting deadlines have already passed, and the financial impact of being out of compliance can be significant.

Implement an effective compliance strategy to avoid financial penalties.

The main factor in determining an individual warehouses’ WAIRE Point Compliance Obligation (WPCO) is its annual truck traffic. GNA developed a calculator to determine clients’ WPCO and translate that truck traffic into the financial penalties that will be charged for non-compliance. This simplified version provides an estimate of potential fees if no action is taken to offset the WPCO of the warehouse.

Note: A truck visit includes both an inbound and outbound trip.

Estimated Mitigation Fee Owed*


* $1,000 per WAIRE point
+ 6.25% administrative fee
+ other applicable administration fees
