Diesel Hotline's Example Fleets
Truck and Bus Regulation example fleets for owners of 1 to 3 trucks or buses
The 866-6DIESEL hotline provides information about ARB's heavy-duty in-use diesel regulations. The following calls are examples of fleets that are subject to the Truck and Bus Regulation and consist of three or fewer trucks or buses.
Note: Your fleet may be subject to multiple regulations, depending on what diesel equipment you have in your fleet. These fleet examples summarize portions of ARB’s diesel vehicle regulations and should not be substituted for the actual regulatory language or requirements. The examples are scenarios developed from calls but are not actual calls. Please look over all the provided materials on the TruckStop website and the Truck and Bus Regulation Final Order to make decisions for your fleet.
The following callers may have fleets similar to yours. For heavier trucks, certain engine model years (MY) have similar requirements and deadlines according to the basic schedule. For example, a 1996 MY engine on a heavier truck would have the same requirement as any MY 1996-1999 engines (see the table on the right). This schedule is called "basic" because it is the basic requirement for heavier trucks driving in California that were not reported for any exemptions, provisions or credits. You do not need to report if you follow the basic engine model year schedules for lighter or heavier trucks.
Calls are shown by the number of trucks, lighter or heavier, engine model year and gross vehicle weight rating (GVWR). The calls described in the table below are from December 2012. Click on the fleet and question that is similar to yours.

This fleet owner reported to use the small fleet compliance option, but called this year to get more information about upcoming deadlines for his fleet. Emily answered his call and noted that he had both heavier (>26,000 lbs. GVWR) and lighter trucks (14,001-26,000 lbs. GVWR).
1998: 15,000 GVWR. Emily told the caller this truck would follow the lighter truck schedule which requires a 2010 engine by January 1, 2018 (see table below).
She told him about one credit still available. For the credit, called the "all-in credit," he could install a PM/soot filter by January 1, 2014, on this lighter truck so the truck would not need an engine replacement until January 1, 2023. He gets the extra 5 years because he would meet the criteria of "... all vehicles with a GVWR 26,000 lbs. or less meeting PM BACT..." This option is in the regulation at (f)(4) on page 15. He must report all trucks in his fleet by January 31, 2014, to use this all-in credit for the lighter trucks.
The caller reported the 1999, 30,000 GVWR truck in the ARB TRUCRS system before March 30, 2012. He decided last year he would take the small fleet exemption, so he will put on a PM/soot filter on one of the two heavier trucks before January 1, 2014*, and the second truck before 2015. Regardless whether this is the first or second truck to have the filter installed, it will need to be replaced with a 2010 emission-equivalent engine by January 1, 2020 (1996 - 1999 engine MY trucks have the same requirement).
The 2000 MY, 28,000 GVWR truck was reported along with the 1999 MY engine truck last year. Again, this caller will need to put on a soot filter on this or the 1999 MY engine truck by 2014*, and the other truck by 2015*. This truck will need a 2010 engine by January 1, 2021 (2000- 2004 engine MY trucks have the same requirement).
*For soot filter retrofits, Emily recommended the caller order or purchase the filter prior to September 1 of the year prior to the deadline to ensure his trucks are compliant in the event of a manufacturer delay.
If he retrofitted both the MY 1999 and 2000 with soot filters by January 1, 2014, then both trucks are compliant until 2023 because they would get an all-in credit. In 2023, he would then need the 2010 or newer engine.
More: Emily told the caller to report each filter installation and to make sure the filter is an ARB-verified filter on ARB's list (see the yellow button "Currently Verified Devices"). She sent the caller a link to the Small Fleet Extension FAQ on the TruckStop website which is a handy reference for the same information provided by the diesel hotline.
A caller who has a 1996 engine model year truck with 36,000 lbs. GVWR called in early December 2012 and said his truck was not reported in TRUCRS and does not have a PM/soot filter installed/retrofitted. Josh answered the call and told him he was overdue for reporting (1996-1999 engines needed to be reported March 30, 2012), which he already knew, and suggested that he report right away.
According to our Web page about late reporting, if you own a small fleet with three or fewer vehicles, and you own a heavier truck with a 1996 to 1999 model year engine, you can still report to take advantage of the Small Fleet Option until January 1, 2014. You may be subject to a penalty. The caller can delay installing a filter until January 1, 2014. We recommend that he order/purchase the filter prior to September 1, 2013, to be in compliance, regardless of manufacturer delay.
This caller did not need to report yet because none of her vehicles' engines are between model years 1996-2004. The following information was provided by Brenda of our hotline staff. Brenda divided the regulatory information for this caller's fleet into two options: following the basic schedule by engine model year, or taking advantage of the small fleet compliance option.
If she chooses to follow the basic compliance schedule for heavier trucks, this caller will not need to report in TRUCRS.
1993: 37,000 GVWR. Brenda told the caller this vehicle has no requirement on the basic schedule until January 1, 2015 (see table below). At that time, a 2010 or newer engine must replace the 1993 MY (pre-1994) engine.
2005: 27,000 GVWR. This vehicle (2005 or newer engine with no PM filter) has no requirement on the basic schedule shown below until January 1, 2014. This vehicle will need a PM/soot filter by January 1, 2014 (order by September 1, 2013). Once the filter is installed, her truck will be compliant until 2022 when a 2010 or newer MY engine will be required for 2005 engines.
2010: 28,000 GVWR. This vehicle is fully compliant.
Using Small Fleet Option:
Brenda told the caller the small fleet option would give her an extra year to comply on the older trucks. She will need to report her fleet by January 31, 2014.
1. According to the schedule, one vehicle would need to be equipped with a PM filter to be compliant with the small fleet schedule before January 1, 2014. Her 2010 MY engine truck qualifies as the first vehicle required. It is already compliant so all she needs to do is report by January 31, 2014.
2. A second vehicle needs to be compliant before January 1, 2015. In this case if the owner decides to install a soot filter on the 2005 MY engine it would give her one extra year to comply than if she were following the basic engine MY schedule. The next deadline for this truck would be engine replacement by January 1, 2022.
3. The third vehicle is her truck with a 1993 MY engine. The owner can install a PM filter by 2016 or replace it with one that is equipped with a soot/PM filter. The small fleet option delays the replacement of the truck for one additional year since the truck/ or truck engine needs to be replaced by January 1, 2016, instead of the same date in 2015.
More: Regardless of the option chosen, Brenda recommended that she order and purchase the soot filter by September 1 prior to each deadline to ensure that she is considered compliant by ARB regardless of a manufacturer delay. She also told the caller to report each filter installation and to make sure the filter installed is an ARB-verified filter that is on ARB's list (see the yellow button "Currently Verified Devices"). She sent her a link to the Small Fleet Extension FAQ on the TruckStop website which is a handy reference for the same information provided by the diesel hotline.
Fleet 4. 1996: 38,000 GVWR; 2003 56,000 GVWR already reported, received ARB's November 26, 2012, letter - answered by Chris
The caller was concerned because he received ARB's November 26, 2012, letter regarding compliance and enforcement. He thought the letter was a direct mailing to him and that maybe his fleet is not in compliance even though he reported by the March 30, 2012, deadline. ARB used a DMV mailing list to send the letter. The letter was not specifically generated using information from the TRUCRS database.
Chris returned the call from a voice mail left on the diesel hotline. He reassured the caller that he did not receive the letter due to any compliance issues with his trucks and that the letter was an outreach effort to ensure that diesel truck and bus owners were aware of the deadlines and penalties. Chris told the caller he can go the Truck and Bus reporting page and check the reporting status at the yellow "Check Status" button.
This caller wanted to know what he needs to do to his fleet to comply with the Truck and Bus Regulation. David returned his call, and followed the diesel hotline protocol to make sure the caller was not subject to the Tractor-Trailer GHG, Drayage, or the Transport Refrigeration Unit Regulations.
The caller's 2007 model year engine truck is likely to have an original equipment manufacturer (OEM) installed PM/soot filters, but some do not. David asked the caller if his truck has an OEM filter. The caller said that the truck did have the OEM filter. David told him his truck is compliant until January 1, 2023. At that time, he will need to replace the truck or its engine with a 2010 emission equivalent engine. January 1, 2023, is the final deadline in this regulation. All trucks will need to have 2010 emission equivalent or newer engines by this date.
If this caller did not have an OEM filter, he should purchase a filter by September 1, 2013, (to be protected from manufacturer delays) to meet the deadline of January 1, 2014. Since it is a 2007 MY engine, he then would have until 2023 to replace the engine according to the basic engine model year schedule.
An owner called the hotline in mid-December 2012 to see if any credits are still available for his two lighter trucks. According to the basic engine model year schedule for lighter trucks, one of his trucks needs a 2010 or newer engine by January 1, 2015, and the other by January 1, 2017. Alexa answered his call and told him he has two options to keep his trucks longer including a credit called the "all-in credit."
For the first option, Alexa told the owner if he installs a PM filter by January 1, 2014, its engine replacement can be delayed until 2020.
For the "all-in credit," Alexa told him he could install a PM/soot filter by January 1, 2014, on all his lighter trucks to delay their engine replacement until January 1, 2023, because he would meet the criteria of "... all vehicles with a GVWR 26,000 lbs. or less meeting PM BACT...". This option is in the regulation at (f)(4) on page 15. He must report all trucks in his fleet by January 31, 2014, to claim this credit for the lighter trucks. This credit is good for any number of trucks both heavy or light (small or large fleet), but all heavy or all light trucks must have the filters installed by January 1, 2014, and it is only good for that category of trucks (heavy or light).
Alexa recommended that if he chooses to take either credit he needs to order/purchase the soot filter early to make sure they are installed in time to meet the January 1, 2014 deadline.
The owner of a single heavier bus wanted to transport people from Arizona to the Rose Parade in Southern California. He said he heard about the ARB regulations though an association he belongs to and wanted to see what he needs to do to drive his bus into the state. (The following information would be similar for any 1996-2004 MY engine truck or bus.)
Erica answered his call and told him he could register for the small fleet provision to extend his compliance until January 1, 2014. He has never driven the bus in California before. For this option, he should purchase the filter for this bus by September 1, 2013, to be considered compliant by ARB after January 1, 2014, regardless of manufacturer delays. However, if he does not install a filter on this bus, after January 1, 2014, the bus will not be able to operate in California.
Erica told the bus owner he has another option which is to apply for a 3-day pass. Once a year fleets can apply for a temporary 3-day pass to operate one truck or bus in California without meeting the clean-up requirements of the regulation. Fleets that use this provision must register their company information in advance and report the vehicle information three days before the pass is needed. She told the caller to apply for the pass by filling in the form, saving it and then attaching it to an email. Then, he should send it to email@example.com. He may also fax the form, or mail it following the instructions at the same link. The form is also available on the front page of the TRUCRS system.
The owner of a fleet with five trucks called to see if two trucks are gasoline powered, could she use the small fleet compliance option.
Cynthia took this call and told the owner that the small fleet option is based on number of diesel trucks owned that are greater than 14,000 GVWR. Since this fleet owner has only three diesel trucks, she can claim the small fleet option. Cynthia told the owner she needs to report her three diesel trucks to take this option. In her fleet she has two 2005 engines and a 2006 model year engine. Cynthia told her to order/purchase a filter for one of the trucks by September 1, 2013, so that she is compliant by January 1, 2014, and report by January 31, 2014. Next, she will need to install one filter each year to the remaining diesel trucks. Her engines need to be upgraded to 2010 emission standards starting January 1, 2022.
If she owned a truck that was already scheduled for a filter according to the basic engine model year schedule she would have been told by Cynthia to report immediately. According to our Web page about late reporting, if you own a small fleet with three or fewer vehicles, and you own a heavier truck with a 1996 to 1999 model year engine, you can still report to take advantage of the Small Fleet Option until January 1, 2014. You may be subject to a penalty.
Another option for this fleet owner is to follow the basic engine model year schedule for heavier trucks (shown above) for her diesel engines. If a fleet owner follows the basic schedule there is no need to report.
More: Regardless of the option chosen, Cynthia recommended that she order and purchase the soot filter by September 1 prior to each deadline to ensure that she is considered compliant by ARB regardless of a manufacturer delay. She also told the caller to report each filter installation if she is using the small fleet option and to make sure the filter installed is an ARB-verified filter that is on ARB's list (see the yellow button "Currently Verified Devices").
