July 1 Deadline Approaching for Being Placed on CARB Diesel “Parts in Progress List”

Less than 30 days remain for diesel performance parts manufacturers to have these parts placed on the California Air Resources Board’s (CARB) “Parts in Progress List,” thereby providing a one-year period for obtaining emissions compliance for these components. Unless parts have previously been CARB certified, failure to be included on this list by the July 1, 2010, deadline will cause products to fail the current Bureau of Automotive Repair’s (BAR) diesel smog-check program administered in California.

Diesel parts manufacturers choosing to become listed must submit a traditional CARB E.O. application that now includes a requirement that applicants explain how they would institute a recall program for existing products, which may require modification to pass emissions standards. Upon successful completion of these documents, assuming products can reasonably be assured to pass emissions requirements, applicants will be given one year (July 1, 2010–July 1, 2011) to obtain an E.O.

To review the current CARB “Parts in Progress List,” go to, click on “aftermarket parts” and identify and click on the “Parts in Progress List.” While CARB will be updating this list on a frequent basis as the July 1 deadline approaches, only a few weeks remain for SEMA members to obtain additional time for compliance testing and not have vehicles rejected during smog checks.

BAR will be referencing the CARB website to determine which components are on the "Products in Progress List" to identify parts not causing failure of the visual portion in the smog-check inspection procedure. SEMA continues to monitor this program and will provide updates when available.
