FACTS ABOUT
Truck and Bus Regulation Compliance Options
Fleets have flexibility with three compliance options

On December 12, 2008, the California Air Resources Board (ARB) approved a new regulation to significantly reduce particulate matter (PM) and oxides of nitrogen (NOx) emissions from existing on-road diesel vehicles operating in California. The regulation requires affected trucks and buses to meet performance requirements between 2011 and 2023. By January 1, 2023, all vehicles must have a 2010 model year engine or equivalent. For general information about the regulation, see Overview of the Truck and Bus Regulation. This fact sheet describes the three primary compliance options fleets can use.

What compliance options do fleets have?

Fleet owners can comply with the regulation by meeting any one of three compliance options. The options provide alternative methods to phase-in best available control technology (BACT) to reduce oxides of nitrogen (NOx) and particulate matter (PM). Vehicle owners can install the highest level PM exhaust filter on existing engines to meet the PM BACT requirements and can replace existing vehicles or engines with engines manufactured to the 2010 model year or newer engine emissions standard to meet the NOx BACT requirements. Fleets can also receive credit for using other methods that achieve the same emissions reductions from existing engines.

A fleet may comply with the replacement requirement by replacing an existing vehicle with one that has a 2010 model year engine or with one that has a later compliance date on the schedule.

For example, a fleet owner with a 1994 engine could meet the January 1, 2013 compliance requirements by replacing the existing truck with one that has a 2007 model year engine originally equipped with a PM filter. According to the schedule no further action would be required for that truck until 2021. By 2021, the truck would need to be replaced with an 11 year old truck or newer. In this way, a fleet could comply by purchasing used vehicles and would not need to purchase any 2010 model year engines until 2021.

Option 2 - BACT Percentage Limits

The BACT percentage limits compliance option provides fleets more flexibility in determining which vehicles to upgrade first. Fleets using this option must report their fleet information each year. The middle column of Table B identifies the minimum percentage of the fleet’s engines that need to have PM filters whether they are aftermarket installations or are originally equipped. The right column identifies the minimum percentage of the fleet’s engines that need to have 2010 model year engines (or equivalent emissions) to meet the NOx BACT requirements.

By 2013, the fleet would need to replace one vehicle (25% of the fleet) with one having a 2010 model year engine. Since the engine is originally equipped with a PM filter, the fleet would have 3 out of 4 trucks with PM filters and would also meet the 75% PM filter requirement for that year. By 2014, the having a 2010 model year engine originally equipped with a PM filter. The regulation would require no further action from the fleet until 2017 when one of the trucks with an aftermarket PM filter would need to be replaced, and by 2020 the fourth vehicle would need to be replaced.

Option 3 - Fleet Average
The fleet averaging option allows a fleet to gradually reduce their fleet emissions by meeting a fleet average emissions target for PM and one for NOx. The fleet emission targets for PM decline from 2011 so that by 2014 all engines will have PM filters. The NOx emissions targets decline from 2013 so that by 2023 all engines will have emissions equivalent to a 2010 model year engine. This compliance option provides credit for emissions reductions from a wide variety of emissions control technologies and alternative fueled vehicles, and provides the most flexibility in choosing which methods to reduce the average emissions for the fleet. Fleets using this option must report their fleet information each year.

The average emissions calculated for the fleet must be less than or equal to the targets specified in the regulation for each compliance year. The NOx and PM emissions factors and targets for
each engine are based on the engine model year and vehicle weight class. If an exhaust retrofit is used, the emissions factor of the engine is reduced by the percent reduction for which the exhaust retrofit has been verified. A fleet can comply by having some engines with emissions factors above the target provided the fleet also has a number of engines with emissions factors below the targets so that the average meets the goal. The emissions factors and emissions targets for both PM and NOx are listed in the regulation and are included in compliance tools that automatically do the calculations.

Do I need to declare which compliance option I intend to use?
No, once the requirement of any one compliance option is met for PM and any one option is met for NOx, the fleet is in compliance. Fleets can use different compliance options each year. A fleet calculator spreadsheet is available at www.arb.ca.gov/msprog/onrdiesel/calculators.htm to allow fleet owners to evaluate different compliance options for their own fleet. The calculator determines when any of the 3 options are met. The calculator also accounts for vehicles that qualify for credits, delays and other provisions and highlights when any of the three options are met for either pollutant.

Truck and Bus Regulation Reducing Emissions
from Existing Diesel Vehicles
Rules to achieve significant emission reductions and protect public health.
In December 2008, the California Air Resources Board (ARB) approved a new regulation to significantly reduce emissions from existing trucks and buses operating in California.

Why is this regulation needed?
Most diesel trucks and buses, which can last 20 years or longer, have little or no emission controls. As a result, these vehicles emit large amounts of smog forming oxides of nitrogen (NOx), and toxic soot (also known as particulate matter or PM). All told, trucks and buses account for about 30 percent of the statewide emissions of NOx and about 40 percent of all diesel PM emissions. Emissions from trucks contribute to many adverse health effects, including about 4,500 premature deaths per year. Reducing emissions from in-use trucks and buses is necessary to meet federally imposed clean air standards and to reduce the adverse health effects from truck and bus pollution.

What types of vehicles are subject to the regulation?
Affected vehicles include on-road heavy-duty diesel fueled vehicles with a gross vehicle weight rating (GVWR) greater than 14,000 pounds, yard trucks with off-road certified engines, and diesel fueled shuttle vehicles of any GVWR. Out-of-state trucks and buses that operate in California are also subject to the regulation. Drayage trucks and private utility-owned vehicles are subject to the regulation beginning January 1, 2021.

Who must comply with the regulation?
Any person, business, school district, or federal government agency that owns, operates, leases or rents affected vehicles. The regulation also establishes requirements for any in-state or out-of-state motor carrier, California-based broker, or any California resident who hires or dispatches vehicles subject to the regulation. In addition, California sellers of a vehicle subject to the regulation would have to disclose the regulation’s potential applicability to buyers of the vehicles.

What industries and types of fleets would be subject to the regulation?
Approximately 170,000 businesses in nearly all industry sectors in California, and almost a million vehicles that operate on California roads each year would be affected. Some common industry sectors that operate vehicles subject to the regulation include: for-hire transportation, construction, manufacturing, retail and wholesale trade, vehicle leasing and rental, bus lines, and agriculture.

What does the regulation require?
The regulation requires fleets to install exhaust retrofits that capture pollutants before they are emitted to the air, and to accelerate vehicle replacements to those with cleaner engines. The regulation does not require any vehicles be replaced until 2013, and it never requires all the vehicles within a fleet to be replaced in a single year. In general, the regulation requires owners to reduce emissions in their fleet by upgrading existing vehicles one of three ways. The first option is to install PM retrofits and replace vehicles (or engines) according to a prescribed schedule based on the existing engine model year. The second option is to retrofit a minimum number of engines each year with a high level PM exhaust retrofit and to replace a minimum number of older engines with newer engines meeting the 2010 new engine standards. The third option is to meet a fleet average. With this option, a fleet operator can use PM and NOx emission factors established by the regulation to calculate the average emissions of the fleet. Then, by the applicable compliance date each year, the owner can demonstrate that the fleet average emissions for PM and NOx do not exceed the PM and NOx fleet average emission rate targets set by the regulation.

Are there special provisions for low-use vehicles?
Vehicles that operate less than 1,000 miles and 100 hours per year in California, are exempt from the vehicle cleanup requirements of the regulation. In addition, vehicles greater than 33,000 pounds GVWR operating less than 7,500 miles per year and vehicles less than 33,000 pounds GVWR operating less 5,000 miles per year would be required to have a PM retrofit but would not be subject to engine or vehicle replacement requirements until January 1, 2021.

What other special provisions are provided?
The regulation also has a number of provisions or delays for low-use vehicles, agricultural vehicles, motor coaches, certain unique vehicles, and vehicles operated in cleaner areas of the state. However, by January 1, 2023, all engines would meet the 2010 new engine emission standards.

What if a diesel retrofit is not available or can not be safely installed for a particular vehicle?
Fleet owners may request a one-year extension of the PM compliance deadline if they document that the highest level verified PM exhaust retrofit cannot be safely installed or is unavailable.

When does the regulation take effect?
For most fleets, the first performance requirements for PM do not begin until January 1, 2011, followed by engine replacement requirements to reduce NOx emissions starting January 1, 2013. For fleets with three or fewer affected vehicles, none of the performance requirements begin until January 1, 2014. The regulation is phased in such that by January 1, 2023, all vehicles must have a 2010 model year engine or equivalent.

What are the requirements for school buses?
School buses are required to meet the proposed PM requirements and would be subject to several special provisions and timetables specifically designed for school buses. School buses manufactured prior to April 1, 1977, will be required to be removed from service by January 1, 2012; otherwise school bus replacements are not required. All remaining buses may meet one of
the three proposed compliance options to reduce PM emissions.

What are the estimated benefits of the regulation?
The regulation is projected to provide significant diesel PM and NOx emissions reductions that would have a substantial positive air quality impact throughout California. PM emissions are projected to be reduced by about 13 tons per day in 2014 and 3.5 tons per day in 2023. NOx emissions are projected to be reduced by about 124 tons per day and 98 tons per day, for 2014 and 2023, respectively. These reductions are critical towards meeting federal clean air standards. The regulation would also reduce diesel PM emissions by the maximum level achievable from inuse on-road diesel vehicles. Staff estimates that approximately 9,400 premature deaths statewide would be avoided by the year 2025 from the implementation of the regulation, and would provide associated health benefits of $48 to $69 billion.

What are the estimated costs to consumers from the regulation?
The cost impact of the regulation is not expected to be significant. While it is expected that most fleets will pass through these costs to their customers, this is expected to result in a negligible impact on consumers, equating to about a few cent increase for a pair of shoes, less than one one hundredth of a cent increase per pound of produce, or an increase of from $3 to $10 for a new car.

Is incentive money available?
Incentive funds are available in many areas of the state. Please see the ARB website or the related fact sheet on financial incentives for additional information.

Small Fleet Provisions:
Less stringent requirements for owners of three or fewer vehicles.
On December 12, 2008, the California Air Resources Board (ARB) approved a new regulation to significantly reduce emissions from existing on-road diesel vehicles operating in California. The regulation requires affected trucks and buses to meet performance requirements between 2011and 2023. By January 1, 2023 all vehicles must have a 2010 model year engine or equivalent. For
general information about the regulation, see Overview of the Truck and Bus Regulation. This fact sheet discusses the regulation’s less stringent provisions for small fleets.

How does the proposed regulation define a small fleet?
A small fleet is any fleet operating in California with one to three vehicles.

What would the regulation require of small fleets and when would the requirements take effect?
Small fleets are exempt from the clean-up requirements until January 1, 2014 and may keep one vehicle that has a 2004-2006 model year engine with a PM filter until January 1, 2019. Reporting requirements start in 2011. A small fleet may comply with the same compliance options and take advantage of special provisions as other fleets. Table A shows various engine model years that meet the 2014 requirements and the earliest date the engine would need to be replaced or upgraded according to the best available control technology (BACT) compliance schedule for any fleet.
Engine Model Years Complies Until
2003 - 2004 with PM filter 2016*
2005 - 2006 with PM filter 2017*
2007 2021
2008 2022
2009 2023
2010 Done
* Small fleets may keep one 2004-2006 engine with PM filter until 2019.
The following are some examples of how small fleets that do not qualify for the special provisions could comply starting January 1, 2014.
One Truck Fleet
• one truck with a 2004‑2006 engine equipped with a PM filter until January 1, 2019, or
• one truck with a 2007 or newer engine originally equipped with a PM filter
would not be subject to any requirements until 2021, as shown in Table A.
Two Truck Fleet
• one truck having a 2004-2006 engine equipped with a PM filter until January 1, 2019, and one with an engine complying with the schedule shown in Table A; or
• one truck with a 2010 model year engine or newer and another truck with any model year engine equipped with a PM filter until 2017. By 2017, the second vehicle could be replaced with one having a 2010 model year engine or newer and the fleet would have met the regulation’s requirements early. The fleet owner could instead replace the second vehicle by 2017 with a 2007 to 2009 model year engine and comply per the schedule in Table A.
Three Truck Fleet
• one truck having a 2004-2006 model year engine equipped with a PM filter until January 1, 2019 and the other two with engines complying with the schedule shown in Table A; or
• If one truck has a 2010 model year engine or newer, and another vehicle complies with Table A, the third vehicle is not subject to the clean-up requirements until 2016. Starting 2016, the fleet must comply with Table A.

Why does the proposed regulation include different, less stringent requirements for small fleets?
Almost 50 percent of the affected vehicles registered in California are owned by fleets that have three or fewer diesel vehicles. Small fleets tend to operate older vehicles and have fewer financial resources available to them when compared to larger fleets. Because of the limited number of vehicles in each of these fleets, small fleets are typically not able to effectively take full advantage of flexibility options provided in the regulation. Finally, providing additional time lowers the cost of compliance and provides more opportunities for small fleets to take advantage of incentive funding.

Are there any special provisions small fleets may take advantage of?
Yes, small fleets may also take advantage of any of the special provisions in the regulation. There are less stringent provisions for vehicles operated less than 7,500 miles per year, manufacturer delays, agricultural vehicles, unique vehicles, motor coaches, and other provisions. However, by January 1, 2023, all engines meet the 2010 new engine emission standards.

Will incentive funding be available to help small fleets?
Yes, there are a number of incentives programs available to small fleets. California has the largest clean air incentive program in the nation, the Carl Moyer Program, with more than $140 million available each year primarily through the local air districts for on-road, off-road, and other diesel engines. Changes have been made to the Carl Moyer Program Guidelines to more effectively assist small fleets. These changes would make small fleets eligible for incentive funding to comply with the January 1, 2014 compliance deadline through the end of 2010. In addition, the first vehicle in a small fleet could be eligible for incentive funding up to January 1, 2014, if being replaced with one having a 2010 model year engine. In addition, through the Goods Movement Emissions Reduction Program (created by Proposition1B), $360 million has been allocated to reducing emissions from trucks transporting goods through key transportation corridors (with another $400 million for trucks going to ports and rail yards). Small fleets may be eligible if replacing their truck two years in advance of regulatory requirements. Small fleets are also the focus of a grant and loan guarantee for truck owners. Many Federal and State programs are administered by local agencies so vehicle owners should check with their local air quality management district for funding opportunities.

Agricultural Vehicle Provisions:
Less stringent requirements for owners of agricultural vehicles
On December 12, 2008, the California Air Resources Board (ARB) approved a new regulation to significantly reduce emissions from existing on-road diesel vehicles operating in California. The regulation requires affected trucks and buses to meet performance requirements between 2011 and 2023. By January 1, 2023, all vehicles must have a 2010 model year engine or equivalent. For general information about the regulation, see Overview of the Truck and Bus Regulation. This fact sheet discusses the less stringent provisions for certain agricultural vehicles.

How does the proposed regulation define an agricultural vehicle?
An agricultural vehicle is one that meets one of the following definitions:
• A vehicle required to have a hazardous material placard and is used
exclusively to deliver fertilizer or pesticides to a farm.
• A vehicle owned by a farming business that is used exclusively in agricultural operations without compensation. Examples include farm trucks used to pick up supplies, mend fences, move cattle, and other farming operations, but not personal use vehicles or vehicles leased to others.
• A truck that is designed for and used exclusively in agricultural operations and is operated for compensation such as manure spreaders, feed mixers, and bale processors, but does not include support vehicles used to service equipment or to transport workers, equipment or supplies. Water trucks used exclusively on farms are also included.
• A truck used exclusively to transport unprocessed agricultural products to the first point of processing. Examples include trucks transporting crops from the farm to a packing shed, cotton to a cotton gin, or logs from the forest to the saw mill.

What is a farming business?
A farming business is a business that operates or manages a farm for profit, either as owner or tenant. It does not include farm support businesses such as soil preparation services, farm labor companies, or businesses providing other agricultural services such as farm management for a fee or on a contract basis.

What are agricultural operations?
Agricultural operations include the activity of growing or harvesting crops for the primary purpose of making a profit including horticultural, viticultural, aqua cultural, forestry, dairy, livestock, bee, or farm product. It also includes the cutting or removing of timber, solid wood products, and biomass
from forestlands for commercial purposes.

What are the provisions that apply to lower mileage agricultural vehicles?
Vehicles qualifying for the lower mileage vehicle exemptions are limited to the number of qualifying vehicles initially reported and must be labeled. Starting January 1, 2010, agricultural vehicles that operate below the annual mileage thresholds shown in Table 1, based on engine model year, are exempt from the PM filter and replacement requirements until January 1, 2017. By
January 1, 2017, these vehicles must comply with the regulation like non‑agricultural vehicles.
Table 1
2006 or newer engines less than 25,000 miles per year
1996 through 2005 engines less than 20,000 miles per year
Pre-1996 engines less than 15,000 miles per year
Starting January 1, 2010, agricultural vehicles that drive less than 10,000 miles each year are exempt from the PM filter and replacement requirements until January 1, 2023. To maintain this exemption, these vehicles can never be operated more than 10,000 miles in any calendar year.
Each year, the number of agricultural vehicles qualifying for the lower mileage exemptions may not increase, but the vehicles may be replaced if the following conditions are met:
• The replacement vehicle is at least one year newer than the one being replaced,
• The total mileage for the replacement vehicle and the one being
replaced continues to meet the mileage limits, and
• The number of vehicles that qualify for the provisions does not increase.

What are the provisions for certain specialty agricultural vehicles?
Vehicles that are approved as specialty agricultural vehicles are exempt from the retrofit and engine replacement requirements until January 1, 2023 and must be labeled. These vehicles have no mileage restrictions, but are limited to 1,100 vehicles in the San Joaquin Valley and 2,200 statewide.
Once the limits are reached no more vehicles will qualify as specialty agricultural vehicles.
Specialty agricultural vehicles are limited to the following body types and uses:
• cotton module movers
• water trucks used exclusively on the farm
• feed trucks used to dispense food specifically at calf and cattle feedlots
• nurse rigs used exclusively to re-supply airplanes or helicopters.

How are the vehicles in the fleet that do not qualify as agricultural vehicles treated?
Vehicles that do not qualify for the agricultural vehicle provisions must meet the requirements of the regulation like other non-agricultural vehicles. There are three compliance options that include the Best Available Control Technology (BACT) compliance schedule, the BACT percentage limits, and the fleet averaging option. The details of these options can be found in the regulatory language. In addition a fleet calculator is available to assists fleet owners in developing their own compliance programs. Additional information is provided in the Truck and Bus Regulation General Overview.

What are the reporting requirements for agricultural vehicles?
By January 31, 2010, fleets utilizing the agricultural vehicles provision must report information on the fleet as it existed on January 1, 2009, and report annually thereafter.

Special Provisions:
Exemptions and credits delay some of the clean-up requirements
The Air Resources Board (ARB) approved a new regulation in December 2008 to significantly reduce emissions from existing on-road diesel vehicles operating in California. The regulation requires affected trucks and buses to meet performance requirements between 2011 and 2023. By January 1, 2023, all vehicles must have a 2010 model year engine or equivalent. For general information about the regulation, please see Overview of the Truck and Bus Regulation. This fact sheet describes the exemptions, delays and credits available in the regulation for certain vehicle types and certain situations.

How do fleets take advantage of the special provisions in the regulation?
Fleets that qualify for credits or have vehicles that qualify for special provisions can delay some of the vehicle replacement or PM filter requirements. Fleets who use the special provisions must report information about all of their vehicles.

I own one truck. Do I have to meet requirements on the same schedule as large fleets?
No, there are optional provisions for fleets with 3 or fewer vehicles that delay the first clean-up requirements until January 1, 2014. Please see the Truck and Bus Regulation Small Fleet Provisions
for details.

I have retired several vehicles from my fleet. Are there any provisions for this?
Yes, fleets that have fewer vehicles compared to July 1, 2008, may claim credit for each vehicle retired. The credit expires in 2014, and, effectively delays the clean-up of another vehicle by one year.

I drive my truck infrequently. Are there are any special provisions for low-mileage vehicles?
Yes, truck tractors or vehicles with gross vehicle weight rating (GVWR) greater than 33,000 pounds that operate fewer than 7,500 miles per year are exempt from any replacement requirements until2021; however, they do need to meet the PM filter requirements. If a truck uses power take off (PTO) to perform work while stationary, the annual engine hours would also need to stay below 250 hours to qualify. All other vehicles would be eligible for the same delay if operated less than 5,000 miles per year (and less than 175 hours per year if PTO is used while stationary). Vehicles that operate less than 1,000 miles per year, and less than 100 hours per year in California, are exempt from any clean-up requirements. However, these vehicles must have functioning odometers and hour meters to qualify. Out-of-state vehicles may also qualify if the fleet owner can document vehicle usage in California. Once a year, out-of-state fleets can also apply for a pass to operate one truck not meeting the clean-up requirements.

I have a unique vehicle that cannot be replaced with a used one. Do I have to buy a new one?
No, if there isn’t a used vehicle available with a 2007 model year engine or equivalent that performs a similar function, then the vehicle would not need to be replaced until 2021. The owner would need to install an exhaust retrofit that reduces NOx emissions, if available, and would need to meet the PM filter requirements. Cab-over engine truck tractors that exclusively pull 57 foot
trailers can be operated until January 1, 2018, before having to be replaced, provided the engine is a 2004 model year engine and meets the PM filter requirements.

Are there any provisions for vehicles that operate in parts of the state where the air is cleaner?
Yes. Any vehicle that operates exclusively in less polluted areas of the state is exempt from the replacement requirements until 2021, but remains subject to the PM filter requirements. The areas are the counties of Alpine, Colusa, Del Norte, Glenn, Humboldt, Lake, Lassen, Mendocino, Modoc, Monterey, Plumas, San Benito, San Luis Obispo, Santa Cruz, Shasta, Sierra, Siskiyou, Trinity, Tehama, and Yuba. There are no usage limits for this provision, but fleets must install GPS tracking systems on those vehicles for documentation purposes.

I have trucks that support emergency operations. Are they exempt like emergency vehicles?
No, they remain subject to the regulation; however, the usage accrued when the vehicle is used for emergency operations can be excluded when determining the annual usage. This may allow the vehicle to qualify for the low usage provisions. The owner must keep records documenting dispatch
by a governmental emergency management agency for travel to and from an emergency event.

Is there any credit for hybrid or alternative fueled vehicle?
Yes. Although not required, a fleet can report alternative fueled vehicles in their fleet average to claim credit. Alternative fueled engines would have a PM emissions factor of zero and a NOx emissions factor consistent with the engine certification model year. Hybrid vehicles that achieve 20 percent fuel economy improvements, compared to a similar diesel vehicle, can receive double credit towards the PM and NOx requirements until 2017.

Will I be penalized if a replacement vehicle that I have ordered is delayed?
If the replacement vehicle, engine or exhaust retrofit is purchased 4 months before the compliance date, the fleet will be considered to be in compliance and will not be penalized.

Is there any benefit for installing a PM filter before the first compliance date?
Yes, a vehicle that has the best available PM exhaust retrofit installed prior to 2010 will be exempt from the NOx performance requirements until 2014.

Do school buses have to meet the same requirements as other trucks?
No, school buses have to meet similar PM requirements and do not have to be replaced except for pre-1977 model year buses. See the fact sheet Truck and Bus Regulation School Bus Provisions.

Are there any provisions for agricultural use trucks?
Yes, there are provisions for vehicles used exclusively for agricultural operations, for supplying agricultural chemicals to farms, and for hauling agricultural products to the first point of processing. The provisions are described in Truck and Bus Regulation Agricultural Vehicle Provisions.

Many bus fleets have motor coaches, do they have more time?
Yes, motor coaches that are 35 feet or longer, with a separate luggage compartment and with seating for 40 or more passengers, are exempt from the replacement requirements until 2017. Beginning January 1, 2017, motor coaches must meet a different (NOx) phase-in schedule.

If a PM filter is not available or cannot be installed safely, do I have to replace the engine?
For a given vehicle, if a PM exhaust retrofit cannot be installed safely, or is not available at least 10 months prior to the next compliance date, it will not be required to be installed. If by 2018, there is still no verified exhaust retrofit, the engine will be required to be replaced.

What are the requirements for on-road cranes and street sweepers with two engines?
Both engines of privately and federally owned two-engine street sweepers are subject to the regulation and both must b e cleaned-up on the same schedule. Both engines of two-engine on road cranes are now subject to the In-Use Off-Road Vehicle Regulation. More information about the regulation is available at: www.arb.ca.gov/msprog/ordiesel/ordiesel.htm

Fleet Assessment:
What is a compliance plan?
A compliance plan is a way to determine what you will need to do to meet the requirements of the regulation. It will allow you to determine, out of your fleet, which vehicles to retire, replace, re-power, install exhaust retrofits on, designate low-use, or other actions which will reduce emissions and comply with the regulation.

How important is a compliance plan?
Finding an appropriate and effective method to comply with the regulation is extremely important. The cost of complying in an individual year can vary by a large amount, depending on the compliance method. Two fleets with the exact same vehicles could have very different costs if one plans ahead and the other does not.

Off Road Fleet Size
Fleets are classified by size as described below.  A fleet must meet large fleet requirements if the total vehicles under common ownership or control would be defined as a large fleet. A fleet must meet medium fleet requirements if the total vehicles under common ownership or control would be defined as a medium fleet. Individual federal or state agencies may report as separate fleets, but all vehicles owned by agencies of the United States or the State of California agencies must meet the large fleet requirements. Low-use vehicles, dedicated snow-removal vehicles, and vehicles used solely for emergency operations need not be included in the total maximum power used to classify fleets by size.

(A) “Large Fleet”
– A fleet with a total maximum power (as defined below) greater than 5,000 horsepower (hp). A fleet must meet large fleet requirements if the total vehicles under common ownership or control would be defined as a large fleet. All fleets owned by the United States, the State of California, or agencies thereof (i.e., an agency in the judicial, legislative, or executive branch of the federal or state government) will be considered as a unit whole and must meet the large fleet requirements.

(B) “Medium Fleet”
– A fleet that is not a small or large fleet.

(C) “Small Fleet”
– A fleet with total maximum power of less than or equal to 2,500 hp that is owned by a business, non-profit organization, or local municipality, or a local municipality fleet in a low population county irrespective of total maximum power, or a non-profit training center irrespective of total maximum power.
