TITLE 13. CALIFORNIA AIR RESOURCES BOARD 

NOTICE OF PUBLIC HEARING TO CONSIDER THE PROPOSED AMENDMENT OF 

THE AIRBORNE TOXIC CONTROL MEASURE FOR IN-USE DIESEL-FUELED 

TRANSPORT REFRIGERATION UNITS (TRU) AND TRU GENERATOR SETS, AND 

FACILITIES WHERE TRUs OPERATE 

The Air Resources Board (ARB or Board) will conduct a' public hearing at the time and 

place noted below to consider the adoption of amendments to the regulation affecting 

transport refrigeration units (TRU) and TRU generator sets (TRU gen set) (collectively, 

TRUs and TRU gen sets shall be referred to as TRUs). 1 As explained in greater detail 

below, the proposed amendments would change the in-use performance standards for 

model year (MY) 2003 and certain 2004 TRU engines. The Board will also be 

considering amendments that would clarify the requirements for "flexibility" engines 

used in TRUs by original equipment manufacturers under the Transitional Program for 

Equipment Manufacturers and would require TRU original equipment manufacturers to 

report certain TRU production data.

INFORMATIVE DIGEST OF PROPOSED ACTION AND POLICY STATEMENT 

OVERVIEW 

Sections Affected: Proposed amendments to California Code of Regulations (CCR), 

title 13, Division 3, Chapter 9, Article 8, section 2477. 

Background: Over 90 percent of Californians breath~ unhealthful air at times. To 

·improve air quality and huritahhealth, ARB establishes req4irements to reduce· 

1 Tiile 13, CCR section 2477 is known as the Transport Refrigeration Unit Airborne Toxic Control Measure 

and establishes in-use performance standards, record keeping, anGI facility reporting requirements for 

TRUs and TRU generator sets. 
emissions from new and in-use on~road and off-road vehicles, engines, and other 

source~. 

In 1998, the Board identified particulate matter emissions from diesel-fueled engines as 

a toxic air contaminant. Two years later, in September 2000, the Board adopted the 

Risk Reduction Plan to Reduce Particulate Matter Emissions from Diesel-Fueled 

Engines and Vehicles (Plan). ·The Plan established a goal of. reducing emissions and··· · 

the resultant health risk from virtually all diesel-fueled engines and vehicles within the 

State of California by the year 2020. The Plan included a goal of reducing diesel PM by 

85 percent in 2020 from the baseline emissions in 2000. The Plan also identified 

various control measures for achieving the goals. These measures included new, more 

stringent st<Jndards for all new diesel-fueled engines and vehicles, the replacement of 

older in-use engines with new, cleaner engines, the use of diesel emission control 

strategies on in-use engines, and the use of low-sulfur and alternative diesel fuels. 

TRU diesel engines currently emit approximately 1.6 tons per day of diesel PM. Staff 

believes that there are situations where the estimated 70-year potential cancer risk 

resulting from exposure to diesel PM emissions from TRUs is in excess of a 100 in a 

million. This is because of the high cancer-causing potential of diesel PM and the 

potential for large numbers of TRUs to operate at one location, such as distribution 

centers located near residential areas. 

· On May 16, 2002, the Board approved the Verification Procedure, Warranty and ln.-Use 

Compliance Requirements for In-Use Strategies to Control Emissions from Diesel 

Engines (title 13 CCR, sections 2700-2710). This rule establishes procedures for the 

verification of diesel emission control strategies by ARB that can be applied on various 

diesel-fueled engines and vehicles to significantly reduce diesel PM emissions. 

It is important to reduce diesel PM emissions from TRUs. Health and Safety Code 

sections 39666 and 39667 requires the ARB to adopt regulations to achieve the 

maximum possible reduction in public exposure to TACs through the application of best 

available control technology (BACT), or a more effective control method, in 

consideration of cost, risk, environmental impacts, and other specified factors. 

ARB adopted the TRU Airborne Toxic Control Measure (ATCM) in 2004. The TRU 

ATCM is part of ARB's ongoing effort to reduce PM emissions from diesel-fueled 

engines and vehicles and improve air quality. The TRU ATCM established in-use 

performance standards for TRUs and TRU gen sets that were to be phased in 

·commencing on December 31, 2008. In March 2005, staff requested the 

U.S. Environmental Protection Agency (U.S. EPA) to grant authorization to ARB to 

adopt and enforce the TRU ATCM pursuant to Clean Air Act (CAA) section 209(e)(2). 

U.S. EPA granted California authorization on January 16, 2009. Because U.S. EPA's .. 

authorization was granted after the first compliance date, ARB delayed the enforcement 

of the TRU ATCM's in-use performance standards until January 2010. 

2 
ARB staff has prepared an Initial Statement of Reasons (ISOR) for the proposed 

amendments to the Airborne Toxic Control Measure for In-Use Diesel-Fueled TRUs and 

TRU Gen Sets, and Facilities where TRUs Operate. 

Description of the Proposed Regulatory Action: 

ARB staff is proposing to amend the TRU ATCM that the Board approved for adoption 

onFebruary 26, 2004, and became effective December10, 2004. The primary purpose 

.. ofthe proposed amendments is to chahge1he in-Lise performance standard for 

MY 2003 TRU engines in the 25 hp and greater category and MY 2003 and MY 2004 

engines in the less than 25 hp category from the ultra-low-emission TRU (ULETRU) 

in-use performance standard to allow TRU owners to comply by either meeting the 

ULETRU standard or, as an option. the less stringent low-emission TRU (LETRU) 

in-use standard. The initial compliance deadlines for MYs 2003 and 2004 TRU engines 

are December 31, 2010 and December 31, 2011, respectively. The proposed 

amendments would also require that all MY 2003 and MY 2004 engines meet the 

ULETRU standard seven years after the initial compliance date (in 2017 or 2018). 

Requirements for "flexibility" engines used in TRUs by original equipment manufacturers 

under the federal Transitional Program for Equipment Manufacturers and California's 

equipment manufacturer flexibility program (title 13 CCR, section 2423(d)) would also 

be clarified to provide seven years of operational life to flexibility engines installed 

before the effective date of these amendments. Flexibility engines installed after that 

would have a shorter operational life under the amendments. In addition, the 

amendments would impose new reporting requirements on TRU original equipment 

manufacturers. A rnore detailed description of the proposed amendments is presented 

below. 

Applicability 

The proposed amendments would affect owners. of TRUs and TRU gen sets that 

operate in California that are equipped with MY 2003 engines, regardless of horsepower 

category, and MY 2004 engines in the less than 25 hp category. This would inClude all 

TRU and TRU gen set owners, whether based in California or out-of-state, that 

transport perishable goods using refrigerated trucks, trailers, shipping containers, and 

railcars within the State. Most TRUs are owned or operated by corporations, 

businesses, and individuals. There are a few local municipalities, school districts, and 

correctional institutions that operate TRUs that may be affected. These amendments 

would affect the owners of TRUs and TRU gen sets equipped with "flexibility engines" 

and would also extend the applicability for new reporting requirements to TRU and TRU 

gen set original equipment manufacturers that directly or indirectly sell or offer for sale 

TRUs and TRU gen sets to the California market. There are currently only three 

affected TRU .<:~nd TRU gen set manufacturers. · 

In-Use Emission Standard Amendment 

The amendments would change the in-use standards for MY 2003 TRU and TRU gen 

set engines in the 25 hp and greater power categqry frorn the ULETRU in-use standard 

to allow either the ULETRU standard or, as an option, the less stringent LETRU in-use 

3 
standard. This change would provide owners with more compliance flexibility and is 

needed because ULETRU compliance options presently are .limited and relatively costly 

compared to LETRU compliance costs. The compliance date for meeting one of these 

standards would remain December 31, 2010. Seven years later, by the end of 2011; 

the MY 2003 engines that are still remaining in service would be required to meet 

ULETRU if the owner chose torneettheLETRU standard in 2010. 

The amendments would also change the in-use standard for MY 2003 and MY 2004 

engines in the less than 25 hp category from the ULETRU in-use standard to allow 

either the ULETRU standard or, as an option, the LETRU in-use standard. The 

compliance dates would remain December 31,2010, for MY 2003 engines and 

December 31, 2011, for MY 2004 engines, when the owner must choose to meet one of 

these standards. Seven years later, by the end of 2017, the MY 2003 engines that still 

remain in service would be required to meet the ULETRU standard if the owner chose 

to meet the LETRU standard in 2010. By the end of 2018, the MY 2004 engines that 

still remain in service would also be required to meet the ULETRU standard if the owner 

chose to meet the LETRU standard in 2011. 

Flexibility Engines- "Effective,Model Year" 

The staff is also proposing to amend the requirements for "flexibility" engines that are 

used in TRUs by original equipment manufacturers under the federal Transitional 

Program for Equipment Manufacturers and California's equipment manufacturer 

flexibility program2

. The amendments would clarify that flexibility engines installed 

before the effective date of the amendments would be provided a full seven years of 

operational life from the year of the engine's manufacture before having to meet the 

more stringent ULETRU in-use performance standard. Flexibility engines installed after 

that date would have a reduced operational life given that compliance would be based 

on the last year that the flexibility engine's tier standard was in effect. 

As permitted under federal and State regulations, TRU and TRU gen set original 

equipment manufacturers (TRU OEMs) have installed "flexibility engines" that meet an 

emissions standard tier that is no longer in effect for new engines at the time that the 

equipment is manufactured.3 

To date, TRU OEMs and engine manufacturers have not followed a consistent practice 

in identifying the model year of flexibility engines. While some manufacturers have. 

identified the model year of these engines to be the year of manufacturer of the engine, 

others have identified the model year as being the last year that the emission standard 

tier of the flexibility engine was in effect for new engine certification (under the proposed 

amendments, this second designation is referred to as "effective model year"). The use 

..;•·,··.'---' 

2 Flexibility engines are new engines that are allowed under these programs to be certified to a lower 

emission standard than is"otherwise in effect for new engines at'tliti time of manufacture. 

3 This is affowe(j for a limited number of engines under the federal Transitional Program for Equipment 

Manufacturers and California's equipment manufacturer flexibility program (13 CCR, section 2423{d)) for 

several years after an emissions standard changes to a more stringent tier. 

4 
of the effective model-year designation has adversely impacted the operational life of 

TRUs under the TRU ATCM in that TRU owners must meet in-use performance 

standards seven years after the engine model year. The last year that a prior tier was in 

effect for new engine certification is typically one to two years before the manufacture 

date of the flexibility engine, resulting in the loss of up to several years of operational 

life. In most cases, owners have not been aware of this loss of operational life of the 

TRU engines that they have purchased .. 

To address this issue, staff is proposing that flexibility engines meeting a prior tier new 

engine standard would be allowed to use the actual engine manufacture year to 

determine in-use compliance requirements. For example, a Tier i engine installed in a 

TRU after the Tier 2 new engine emission standards became effective for new engines 

would be allowed to use the engine manufacture year to determine in-use compliance 

requirements. This would ensure that all TRUs with flexibility engines that are 

purchased before the effective date of these amendments receive a full seven years of 

operational life. 

The amendments would further provide that flexibility engines installed in TRUs after the· 

effective date of the amendments would be required to use the "effective model year" of 

the flexibility engine to determine future ULETRU compliance dates. As stated, the 

effective model year of the flexibility engine would be the last year that the flexibility 

engine's tier standard was in effect for new engine compliance. Compliance with the 

in-use standards would then be required by the end of the seventh year after the 

effective model year of the flexibility engine. Using the effective. model year for future 

flexibility engine use would discourage their use since operational life is affected. It 

would also result in dirtier, earlier tier flexibility engines being phased out sooner 

thereby ensuring that the emission reductions intended under the original TRU ATCM 

will be achieved as intended. · 

TRU OEMs would also be required to disclose to the end user at point of sale that the 

unit has a flexibility engine and that there is a loss of operational life associated with the 

use of flexibility engines. They must also provide the end user with the date that the 

engine must meet the ULETRU in-use standard. 

TRU Manufacturer Reporting 

Staff is proposing to amend the TRU ATCM to require that TRU OEMS report 

production information, including information on flexibility engines installed in TRUs. 

This reporting will ensure that manufacturers provide the data necessary for the 

proposed flexibility engine amendments, allow ARB to consider improvements to the 

TRU registration process, and more accurately estimate emissions inventories. TRU 

OEMs would be required to periodically report data on each TRU and installed engine 

produced in future model years. TRU OEMs would also be required to submit reports 

on TRU sales from previous years.

COMPARABLE FEDERAL REGULATIONS 

There are no federal regulations comparable to the TRU ATCM for in-use TRUs. Under 

federal Clean Air Act (CAA) section 213, U.S. EPA is without authority to adopt in-use 

standards for off-road (non-road) engines.4 · 

•. Section2Q9(e)(1) otthe CAA conclusively preempts. states, including California, from·. 

·adopting requirements for new offcroad engines less than 175 hp that are used in farm 

or construction equipment. Under section 209(e)(2), California may adopt and enforce 

emission standards and other requirements for off-road engines and equipment not 

conclusively preempted by section 209(e)(1), so long as California applies for and 

receives authorization from the Administrator of U.S. EPA TRU engines are not used 

in farm and construction equipment and are thus not preempted. California requested 

and received authorization from U.S. EPA for the initially adopted TRU ATCM in 

January 2009s

COSTS TO PUBLIC AGENCIES AND TO BUSINESSES AND PERSONS AFFECTED 

The determinations of the Board's Executive Officer concerning the costs or savings 

necessarily incurred by public agencies and private persons and businesses in 

reasonable compliance with the proposed regulations are presented below. A detailed 

assessment of the economic impacts of the proposed regulatory action can be found in 

the Staff Report. 

Costs or Savings to Businesses and Private Individuals 

In developing this regulatory proposal, ARB staff evaluated the potential economic 

impacts on representative private persons or businesses. The amendments would 

result in compliance cost savings due to changing the in-use standard from ULETRU to 

either ULETRU or LETRU because the Level 2 Verified Diesel Emissions Control 

Strategies (VDECS) required to meet LETRU costs about $2,000 less than the Level 3 

VDECS required to meet ULETRU. The total compliance cost savings related to the 

in-use standard option would be about $2.1 million in 2010 and 2011' assuming about 

30 percent of the affected units will comply by retrofitting (30 percent of the MY 2002 

engines complied by retrofitting, so staff assumed this trend would continue for 

MY 2003 and 2004 engines). However, to the extent that MY 2003 and MY 2004 

engines comply by meeting the LETRU standard in 2010 and are still operating in 2017 

and 2018, respectively, they would need to meet ULETRU standard in that year. This 

would potentially reduce compliance cost savings to a net savings of about $300,000 in 

2010 dollars. The proposed amendments do not affect the cost of repowering a unit 

with a cleaner engine to maintain compliance, which was the compliance option chosen 

for 65 percent of the 2002 units, nor the cbst of using Alternative Technologies (such as 

hybrid electric), which was chosen as the compliance optipn by five percent of the TRU 

owners. 

There are no end-user compliance costs related to the amendment addressing the past 

use of flexibility engines. The TRU OEMs, however, would incur costs related to 

flexibility engine reporting in 2010. Staff estimates these one-time costs would be about 

$19,000, total in 2010 dollars. 

The cost of compliance with the TRU OEM reporting amendment for current year and 

prior year production would be about $25,000 for the initial one-time reports due soon 

after the amendments take effect and about $8,000 per year for periodic update reports. 

Staff anticipates that the cost Of preparing and submitting these will be reduced 

significantly as opportunities to automate this work are phased in. 

7 
The Executive Officer has made an initial determination thl:lt the proposed regulatory 

action would not have a significant statewide adverse economic impact directly affecting · 

businesses, including the ability of California businesses to compete with businesses in 

other states, or on representative private persons. 

In accordance with Government Cod~ sectiori 11346.3, the Executive Officer has 

determined thatthe proposed regulatory action would not affect the creation or 

elimination of jobs within the State of California, the creation of new businesses or 

elimination of existing businesses within the State of California, or the expansion of 

businesses currently doing business within the State of California. A detailed 

assessment of the economic impacts of the proposed regulatory action can be found in 

the ISOR 

The Executive Officer has also determined, pursuant to California Code of Regulations, 

title 1, section 4, that the proposed regulatory action would affect small businesses 

because staff anticipates there will be cost savings if TRU and TRU gen set owners 

choose the retrofit compliance option. Compliance cost would· not be affected if owners 

choose the repower option. 

In accordance with Government Code sections 11346.3(c) and 11346.5(a)(11 ), the 

Executive Officer has found that the reporting requirements of the regulation which 

apply to businesses are necessary for the health, safety, and welfare of the people of 

the State of California. 

Before taking final action on the proposed regulatory amendments, the Board must 

determine that no reasonable alternative considered by the Board, or that has otherwise 

been identified and brought to the attention of the Board, would be more effective in 

carrying out the purpose for which the action is proposed, or would be as effective and 

less burdensome to affected private persons than the proposed action. 

Costs or Savings to Local and State Government Agencies 

Pursuant to Government Code sections 11346.5(a)(5), the Executive Officer has 

determined that the proposed regulatory action would not create any costs to or 

mandates on any local agency or school district that is reimbursable by the State 

pursuant to Government Code, title 2, division 4, part 7 (commencing with section 

17500). 

Pursuant to Government Code sections 11346.5(a)(6), the Executive Officer has further 

determined, based on estirril:ltes prepared in accordance with instruction adopted by the 

Department of Finance, that the proposed regulatory action would not create additioriid 

costs to any State agency or to any local agency or school district, whether or not 

reimbursable by the State pursuant to Government Code, title 2, division 4, part 7 

(commencing with section 17500), create other nondiscretionary costs on local 

agencies, and affect costs or savings in federal funding to the State. 

8 
Several local agencies, school districts, and State agencies own TRUs, so the 

compliance cost savings discussed above may apply to these agencies if they own MY 

2003 TRU engines in the 25 hp and greater power category or MY 2004 TRU engines in 

the less then 25 hp category.
