Low-mileage Work Truck Option

Low Mileage Work Truck Option

This option currently applies to heavier vehicles with a gross vehicle weight rating greater than 26,000 pounds, but will be available for lighter vehicles on January 1, 2015. Once ARB provides the information for lighter vehicles it will be provided.
This option allows owners that meet minimum PM filter requirements each year, from 2014 to 2018, to defer compliance for the work trucks in the fleet that travel less than 20,000 miles per year. Owners can designate which vehicles will use the extension at the beginning of every year or within 30 days of purchasing a vehicle. All work trucks will need to comply with the replacement requirements of the engine model year schedule starting January 1, 2020.
What trucks can use the Low-Mileage Work Truck Option?
Work trucks that can use the option must have been in the fleet on January 1, 2012 or must have a 1996 or newer engine. The trucks must meet one of the following definitions:   
   * Is owned by a company that has a valid California Contractors License, or
   *  Is a tractor trailer combination that exclusively pulls a dump or low-boy trailer, or
   *  Is a truck with an attached body except if it tows a trailer and hauls goods
What is the compliance schedule for low-mileage work trucks?
Each year, before the Low-Mileage Work Truck Option can be used for any truck, the entire fleet of heavier vehicles must meet the minimum PM filter requirements shown in the table below. All heavier vehicles (greater than 26,000 GVWR) except those that are using the low-use exemption must be counted to determine how many filters are needed. For example, assuming you have two heavier trucks in your fleet, and they are both designated as low mileage work trucks, you would need the first filter January 1, 2014 and the second filter January 1, 2017.
This is how it works for two trucks:
Jan. 1, 2014:  2 x 0.33 = 0.66 which rounds up to 1 (first filter required)
Jan. 1, 2015: 2 x 0.40 = 0.80 which rounds up to 1 (assuming you met this requirement the previous year)
Jan. 1, 2016: 2 x 0.60 = 1.2 which rounds down to 1
Jan. 1, 2017: 2 x 0.80 = 1.6 which rounds up to 2 (second filter required)
If you changed the number of vehicles in your fleet in any year, these calculations and the number of filters required would change. Any vehicle that has a PM filter on it already will count toward the PM filter requirement of the Low-Mileage Work Truck Option even if it is not a work truck. If you own one heavy truck you must report like other fleets to claim the Low-Mileage Work Truck Option, and can delay the PM filter requirement until January 1, 2016.
Compliance Date      PM Filters Required*
January 1, 2014                33%
January 1, 2015                40%
January 1, 2016                60%
January 1, 2017                80%
January 1, 2018               100%
*Excludes low use and funded vehicles
After the owner has demonstrated compliance with the PM filter requirements, the remaining trucks can be designated as low-mileage work trucks and will be exempt from the general replacement or retrofit requirements. Starting January 1, 2020, all low-mileage work trucks must comply with the engine model year schedule like other trucks.
Eligible trucks will need to labeled with the letters “WT” with white block lettering that is three inches high on a five inch by eight inch black background on each door. The labels must be in clear view at all times. ARB will not issue the label. You need a properly functioning odometer. If the odometer does not work you must use a hub-odometer that is non-resettable, has a unique serial number, and has a lock-out feature.
