The Los Angeles Harbor Commissioners has adopted a proposed measure that will implement a progressive ban of older trucks from operation at the port of Los Angeles beginning in October 2008, Green Car Congress reports. The ban will reduce port-related truck pollution by approximately 80 percent over a period of just over five years.

The proposed tariff (PDF) will also require mayoral and city council approval by adoption as a city ordinance.

The schedule for the progressive ban is as follows:

• Ban pre-1989 trucks from Port service by October 1, 2008
• Ban 1989-1993 trucks from Port service by January 1, 2010
• Ban unretrofitted 1994-2003 trucks from Port service by January 1, 2010
• Ban pre-2007 trucks from Port service by January 1, 2012

The tariff would not apply to Dedicated Use Vehicles.
