Table 3: Phase-in Compliance Schedule for Vehicles with GVWR greater than 26,000 lbs

Compliance Date Percent of Fleet Complying with
as of January 1 PM BACT
2012 30%
2013 60%
2014 90%
2015 90%
2016 100%
2020 All vehicles must comply with
section 2025(g)
(2) If the calculated number of engines required to be brought into compliance with the percentage limits is not equal to a whole number, the owner shall round up to a whole number when the fractional part of the required number of engines is equal to or greater than 0.5, and round down if less than 0.5.
(3) Vehicles in which public funds contributed to the purchase of the vehicle, repower of the engine, or retrofit of the engine must not be included when determining compliance with PM BACT, unless allowed by the funding program guidelines applicable to the particular source of public funds used for the purchase, nor shall the engine be included in the total fleet for purposes of determining the percent complying with PM BACT.

(5) Fleets complying with this option may also use the credits of section 2025(j), the agricultural provisions of section 2025(m), and the exemptions, delays, and extensions of sections 2025(p).
(6) Fleets may use the extension based on unavailability of highest level VDECS of section 2025(p)(9) for all engine model years.
(j) Credits for Fleets that have Downsized, Early PM Retrofits, Hybrid Vehicles, Alternative Fueled Vehicles, Vehicles with Heavy-Duty Pilot Ignition Engines, and Early Addition of Newer Vehicles

Fleets can take advantage of credits that reduce the number of vehicles with a GVWR greater than 26,000 lbs that must meet the PM BACT requirements in the phase-in option of section 2025(i) as described in subsections (1) to (3) below. These credits do not apply to school buses.

(1) Credit for Fleets that have Downsized

Until January 1, 2016, a fleet that has fewer vehicles with a GVWR greater than 26,000 lbs operating in the compliance year than in the 2006 baseline fleet may claim a credit towards compliance with the phase-in option of section 2025(i) for that year.

(A) The fleet owner may reduce the percent requirement in Table 3 of section 2025(i) by the same percent that the fleet was downsized. For example, a fleet that has 20 percent fewer vehicles operating in 2006 would be able to subtract 20 percent from the annual compliance requirement. That is, if the compliance requirement for the year is 30 percent, the fleet would only need to demonstrate that 10 percent of the existing fleet (30%-20%=10%) met PM BACT.
(B) A vehicle that is not operated in the compliance year may be excluded from the existing fleet in determining the credit if:
1. The vehicle is not driven for the entire compliance year and
a. Either a certificate of non-operation has been issued by the DMV or a request for a non-operation certificate has been filed with DMV prior to the beginning of the compliance year; or
b. An equivalent certificate has been issued by another state or a request for such a certificate has been filed with another state prior to the beginning of the compliance year; or
c. The vehicle is not operated for any purpose during the compliance year except to demonstrate functionality of the vehicle to potential buyers, to move the vehicle short distances for maintenance, or to a storage facility while awaiting sale.
(C) The fleet utilizing this provision must comply with the reporting requirements of section 2025(r)(12) for low-use vehicles and report information for all vehicles in the 2006 baseline fleet pursuant to section 2025(r)(13).
(D) For purposes of determining the credit, all vehicles in the scope and applicability of section 2025(b), except school buses, must be included in calculating the number of vehicles in the 2006 baseline fleet and in the fleet during the compliance year and all vehicles exempt from the regulation in section 2025(c) must be excluded. The number of vehicles calculated at the beginning of the compliance year will include vehicles that are partially paid for by state funds, all drayage trucks, and all on-road vehicles that are now subject to the title 13, section 2449.
(2) A fleet shall receive a credit to treat another vehicle with a GVWR greater than 26,000 lbs as meeting the PM BACT requirements of section 2025(i) until January 1, 2017 as described below in 2025(j)(2)(A) to 2025(j)(2)(C).
(A) Credit for Early PM Retrofit

A credit will be granted for each vehicle, with a GVWR greater than 14,000 lbs, that is equipped with the highest level VDECS for PM by July 1, 2011. The fleet may receive a credit for each vehicle for which the highest level VDECS has been ordered and paid for, or for which at least a 20 percent deposit has been paid, by May 1, 2011 and the VDECS is installed by October 1, 2011. The fleet owner must meet the reporting requirements of section 2025(r)(13) by January 31, 2012 to claim the credit and must meet the record keeping requirements of 2025(s) to document the VDECS purchase and installation.

(B) Credit for Hybrid Vehicles, Alternative Fueled Vehicles, and Vehicles with Heavy-Duty Pilot Ignition Engines Credit will be granted for each vehicle with a GVWR greater than 26,000 lbs that is a fuel efficient hybrid vehicle, an alternative fueled vehicle, or a vehicle powered by a heavy-duty pilot ignition engine that is added to the fleet before January 1, 2017. The fleet owner must meet the reporting and record keeping requirements of section 2025(r) and 2025(s) for the vehicle by January 31 of the compliance year to use the credit. Vehicles with a GVWR between 14,000 lbs and 26,000 lbs may also earn a credit if added to the fleet prior to July 1, 2011. Information required by section 2025(r) and the date the vehicle was added to the fleet must be reported by January 31, 2012. Record keeping information must be maintained as required by section 2025(s). Any alternative fueled engine or vehicle powered by a heavy-duty pilot ignition engine must be counted when determining the number of vehicles in the fleet.
(C) For the same owner, excess PM VDECS credits granted in the Off-road regulation (title 13, CCR, section 2449 ) may be used in the Truck and Bus regulation and excess PM VDECS credits granted in the Truck and Bus regulation may be used in the Off-road regulation until January 1, 2017. Starting January 1, 2017 no credits may be transferred between the regulations.
1. Excess PM VDECS credits earned in the Truck and Bus regulation will be determined for each compliance year. The annual excess PM VDECS credits are determined by counting the number of Level 3 PM VDECS filters and 2007 model year and newer engines that meet PM BACT in the fleet that exceed the minimum number required to meet the PM BACT percentage of section 2025(i) without accounting for the credits specified in sections 2025(j)(2)(A), 2025(j)(2)(B), and 2025(j)(3). The number of excess PM VDECS credits cannot exceed the number of Level 3 retrofit VDECS in the fleet. Excess PM VDECS credits can be used in the Off-Road regulation according to section (title 13, CCR, section 2449.1(b) ).
2. For each compliance year, excess PM VDECS credits earned in the Off-road regulation may be applied as a credit that would treat another vehicle with a GVWR greater than 26,000 lbs in the Truck and Bus regulation section 2025 as compliant in the compliance year when determining compliance with the phase-in option of section 2025(i).
3. Fleets must meet the reporting requirements of section 2025(r)(27) to utilize excess PM VDECS credits.
(3) Credit for Early Addition of Newer Vehicles

The fleet shall receive credit for the addition of a vehicle that has a propulsion engine that is equipped with an OEM diesel particulate filter before January 1, 2012 if the average age of the propulsion engines in the fleet is newer than it was in 2006. Until January 1, 2017, the credit can be applied towards meeting the PM BACT requirements of the phase-in option of section 2025(i).

(A) The credit is a percentage that will be calculated as 5 times the difference in the average age of the 2006 baseline fleet and the average age of the fleet in the compliance year, where:
1. The average age of the fleet in 2006 is calculated as 2007 minus the average of the engine model years in the 2006 baseline fleet.
2. For vehicles that were in the 2006 baseline fleet and are no longer in the fleet as of January 1, 2012, the vehicle model year minus 0.5 will be used in lieu of the engine model year, unless the fleet has documentation demonstrating the engine model year and engine family.
3. The fleet owner may retain the credit after 2012 if the fleet average age stays the same or newer than it was on January 1, 2012, otherwise the credit will be recalculated.
4. Vehicles that use the exemption for low-use vehicles of 2025(p)(4) shall be excluded in determining the credit.
(B) The credit cannot exceed the percentage of the fleet that has 2007 model year or newer engines that meet PM BACT.
(C) The credit shall reduce the PM BACT requirement of the phase-in option in section 2025(i) for the applicable compliance year.
(D) The fleet owner must meet the reporting and record keeping requirements of section 2025(r) and (s) by January 31, 2012.
(4) Credits specified in sections 2025(j)(1) through 2025(j)(3) will not be given for vehicles that were purchased by the fleet or retrofitted to comply with any other California in-use regulation. Credits will also not be given for partially state funded vehicle replacements or retrofits according to the funding program guidelines applicable to the particular source of public funds used for the purchase. Credits are only valid for as long as the vehicle for which the compliance action has been taken remains operational in the fleet or if replaced within 30 days with a vehicle equipped with an engine that meets PM BACT and is at least one model year newer.
(5) Credits are not transferrable except with appropriate documentation of a change of business form approved by the Executive Officer such as sole proprietorship to partnership, partnership to corporation, mergers or acquisitions of the entire company and fleet of vehicles, or for changes such as from estate tax or inheritance tax planning.
(k) Requirements for School Buses

This subsection applies to diesel-fueled school buses as defined in section 2025(d)(53) with a GVWR greater than 14,000 lbs.

(1) Phase-in Requirements for School Buses

Fleets with school buses manufactured on or after April 1, 1977 must comply with PM BACT as defined in section 2025(d)(48), pursuant to the schedule set forth in Table 5 below.

Table 5: Compliance Schedule for School Buses

Compliance Deadline Percent of Fleet Complying
as of January 1 with PM BACT
2012 33%
2013 63%
2014 100%
(2) Credit for School Bus Fleets that have Downsized
(A) Until January 1, 2014, a fleet having fewer school buses on January 1 of the compliance year than it had in the 2006 baseline year may reduce the percent requirement in Table 5 by the same percentage that the fleet has downsized.

For example, a fleet that is 20 percent smaller than it was in 2006 would subtract 20 percent from the annual compliance requirement. If the compliance requirement for the year is 33 percent, the fleet would need to demonstrate that it had PM filters on the 13 percent of the existing fleet (33%-20%=13%).

(B) The credits are not transferrable except with appropriate documentation of a change of business form such as sole proprietorship to partnership or partnership to corporation, or for mergers or acquisitions of the entire company and fleet.
(3) Credits for Hybrid School Buses, Alternative Fueled School Buses, Electric School Buses, and School Buses with Pilot Ignition Engines

Fleets with fuel efficient hybrid school buses, alternative fueled school buses, electric school buses, or school buses with pilot ignition engines shall receive a credit to treat another school bus in the fleet as compliant until January 1, 2014. A school bus with a dual-fuel engine is not eligible. This credit is not available for school buses that were purchased or retrofitted to comply with any other California in-use regulation. This credit is not available if state funds were used to partially or totally replace or retrofit any school bus unless allowed by the guidelines of the program that funded the bus replacement or retrofit.

(4) Extension of Deadline for Unavailability of VDECS

If a school bus engine cannot be equipped with the highest level VDECS for PM the school bus owner must:

(A) Record and submit to the Executive Officer the information listed in section 2025(k)(4)(B) through (E) by January 31 of the applicable compliance year through January 31, 2017. By January 1, 2018, this extension expires and all school buses using this extension must be replaced with vehicles that are equipped with a 2010 model year emissions equivalent engine or with one that complies with the BACT compliance schedule (i.e., a 1998 model year engine or newer school bus equipped with the highest level VDECS for PM).
(B) Describe the reasons that a compliance extension is needed for each engine or engine-vehicle combination annually.
(C) If during the warranty period the VDECS would void the engine warranty, provide a statement from the engine manufacturer, authorized engine dealer, or vehicle dealer that explains why the warranty would be voided.
(D) If no verified VDECS is commercially available, provide a list of VDECS manufacturers that have been contacted and the manufacturers' responses to your requests to purchase a VDECS from them.
(E) If a verified VDECS is commercially available, but the VDECS manufacturer or an authorized VDECS installer does not deem the VDECS to be technologically feasible for the school bus, provide a statement from the VDECS manufacturer or authorized VDECS installer.
(5) Low-use School Buses
(A) School buses operating fewer than 1,000 miles during any compliance year are exempt from the requirements of section 2025(k), but fleet owners must comply with the record keeping requirements of section 2025(s)(3). Such vehicles must have a properly functioning odometer installed at all times.
(B) A fleet owner of a school bus that exceeds 1,000 miles in any compliance year must immediately count the school bus as part of the fleet, bring the fleet into compliance with the requirements of section 2025(k) in the current compliance year, and notify the Executive Officer of the change in status within 30 days of exceeding the mileage limit.
(6) Any school bus manufactured before April 1, 1977, must be retired from service no later than January 1, 2012.

(9) Extension of the PM BACT Compliance Deadline Based on Unavailability of Highest Level VDECS - If an engine that is required to meet PM BACT cannot be equipped with the highest level VDECS for PM, the Executive Officer may grant a one-year extension of the compliance deadline, which may be extended annually through January 1, 2017, based on an evaluation of information submitted pursuant to section 2025(r)(11) that the engine cannot be equipped with the highest level VDECS for PM provided that all other engines in the fleet are in compliance with the requirements for the compliance year. The request must be filed 4 months prior to the compliance deadline. By January 1, 2018, any vehicle that is not equipped with the highest level VDECS for PM must be replaced with a vehicle that meets PM BACT. The extension for unavailability of highest level VDECS applies to the auxiliary engines in two engine sweepers if the engine that provides motive power must meet PM BACT. By January 1, 2018, any auxiliary engine in a two engine sweeper with a GVWR greater than 26,000 lbs that is not equipped with the highest level VDECS for PM must be replaced with Tier 4 off-road engine or an engine that is equipped with the highest level VDECS for PM. The extension does not apply for engines that are required to meet the 2010 model year equivalent requirements.
(10) Extension for Meeting PM BACT by 2014. By January 1, 2014, if every vehicle in the fleet with a GVWR greater than 26,000 lbs is equipped with either a Level 3 VDECS for PM or a 2007 model year or newer engine that meets PM BACT, the vehicles shall be exempt from meeting the 2010 model year emission equivalent engine requirements until January 1, 2023.
(A) Fleet owners must meet reporting requirements of sections 2025(r) by January 31, 2014. The fleet will not need to report again after the initial reporting to retain the extension unless a vehicle or engine is replaced with one that has a 2006 model year or older engine.
(B) The fleet can retain the exemption if an engine or vehicle is replaced with another one that is equipped with a Level 3 VDECS or has a 2007 model year or newer engine that meets PM BACT. The fleet must report the fleet information in accordance with section 2025(o)(2).
(q) Special Provisions for VDECS and Experimental Diesel Emission Control Strategies
(1) VDECS Requirements
(A) VDECS Installation. Before installing a VDECS on a vehicle, the owner must ensure that:
1. The VDECS is verified for use on the engine and vehicle, as described in the Executive Order for the VDECS.
2. Use of the vehicle is consistent with the conditions of the Executive Order for the VDECS.
3. The VDECS is installed in a verified configuration.
4. The engine to be retrofitted must be in its original certified configuration, free of excess oil consumption, must not have malfunctioning fuel delivery systems, or any other mechanical condition that may impair the proper functioning of the VDECS.
5. The VDECS label will be visible after installation.
(B) VDECS Maintenance. If a fleet owner installs a VDECS to meet the requirements of section 2025(e), the VDECS must remain installed until the VDECS fails or is damaged or is replaced with a similar or higher level VDECS. Requirements for VDECS failure or damage are in section 2025(q)(2). The owner of a vehicle retrofitted with a VDECS must ensure that the VDECS and engine are properly maintained as recommended by the respective manufacturers.
(2) Failure or Damage of a VDECS. In the event of a failure or damage of a diesel emission control strategy, the following conditions apply:
(A) Failure or Damage During the Warranty Period. If a VDECS fails or is damaged within its warranty period, and the VDECS manufacturer or authorized dealer determines that it cannot be repaired, the owner must replace the VDECS with the same level or higher level VDECS for the vehicle within 90 days of the failure.
(B) Failure or Damage Outside of Warranty Period. If a VDECS fails or is damaged outside of its warranty period and cannot be repaired, and if the fleet could not meet an applicable target for the most recent compliance date without the failed VDECS, then within 90 days of the failure, the owner must replace the failed VDECS with the highest level VDECS available for the engine at time of failure.
(3) Fuel-Based Strategy VDECS
(A) If a fleet owner determines that the highest level VDECS for a large percentage of the fleet would be a Level 2 fuel verified as a diesel emission control strategy, and implementation of this VDECS would require installation of a dedicated storage tank, then the owner shall request prior approval from the Executive Officer to allow use of the Level 2 fuel-based strategy across its fleet.
(B) Waiver for Discontinuation of Fuel Verified as a Diesel Emission Control Strategy. If a fleet owner has relied upon a fuel verified as a diesel emission control strategy to meet an applicable requirement and has to discontinue use of the fuel due to circumstances beyond the fleet owner's control, the fleet owner shall apply to the Executive Officer no later than 30 days after discontinuing use of the fuel for a compliance waiver of up to two years to provide the fleet owner time to return to compliance with the applicable requirements. The Executive Officer shall respond to the request within 30 days and grant the request upon finding that the application is complete, outlines the compliance strategy to be used, and that all reporting requirements have been met.
(4) Use of Experimental Diesel Emission Control Strategies
(A) If a fleet owner wishes to use an experimental or non-verified diesel emission control strategy to support the verification of a non-verified diesel emission control strategy, the owner must first obtain approval from the Executive Officer for a compliance extension. To obtain approval, the owner must demonstrate either that (1) a VDECS is not available or not feasible for their vehicle or application, or (2) that use of the non-verified strategy is needed to generate data to support verification of the strategy.
1. The application must include the following: emissions data and a detailed description of the control technology that demonstrates that the experimental control strategy achieves at least a Level 2 diesel PM emission reduction, vehicle and engine data, and odometer or hubodometer readings as described in sections 2025(r)(8), 2025(r)(9), and 2025(r)(12)(B).
2. The Executive Officer will treat the strategy as a:
a. Level 2 VDECS if the application demonstrates that the strategy achieves at least 50 percent reduction in diesel PM.
b. Level 3 VDECS if the application demonstrates that the strategy achieves at least 85 percent reductions in diesel PM.
(B) Upon approval by the Executive Officer, each vehicle engine retrofitted with the experimental strategy will be allowed to operate for a specified time period necessary to make a determination that the experimental strategy can achieve the projected emissions reductions. The vehicle equipped with the experimental strategy will be considered to be in compliance under section 2025(f), 2025(g), 2025(h), or 2025(i) during the specified time period. The fleet owner shall keep documentation of this use in records as specified by the Executive Officer.
(C) The fleet owner must bring the fleet into compliance under section 2025(f), 2025(g), 2025(h), or 2025(i) prior to the expiration of the experimental diesel emission control strategy extension.
(5) VDECS That Impairs Safe Operation of Vehicle - A fleet owner may request that the Executive Officer find that a VDECS should not be considered the highest level VDECS available because:
(A) it cannot be safely installed or operated in a particular vehicle application; or
(B) its use would make compliance with occupational safety and health requirements, or an ongoing local air district permit condition impossible.

If a VDECS manufacturer states that there is no safe or appropriate method of mounting its VDECS on the requesting party's vehicle, then the VDECS will not be considered safe.
