TITLE 13. CALIFORNIA AIR RESOURCES BOARD
NOTICE OF PUBLIC HEARING TO CONSIDER ADOPTION OF THE HEAVY-DUTY DIESEL ENGINE SOFTWARE UPGRADE REGULATION (CHIP
The Air Resources Board (the Board or ARB) will conduct a public hearing at the time and place noted below to consider
adopting the proposed heavy-duty diesel engine software upgrade regulation. This proposed software upgrade regulation
would mandate installation of software to reduce emissions of oxides of nitrogen (NOx) from 1993-1999 model year
heavy-duty vehicles. The proposed regulation would also make minor, mostly related, modifications to the Heavy-Duty
Vehicle Smoke and Fleet Inspection programs.
The software upgrades, referred to as low NOx software, were developed in the 1990s as a result of negotiations
between the United States Environmental Protection Agency (U.S. EPA), the ARB, and seven engine manufacturers.
Owners of eligible vehicles and dealers/distributors with the capability to install the software would have responsibilities
under the proposed regulation. This notice summarizes the proposed regulation requirements.

INFORMATIVE DIGEST OF PROPOSED ACTION AND POLICY STATEMENT OVERVIEW
Sections Affected: Proposed adoption of section 2011 in new article 3.5 within chapter 1, division 3, title
13, California Code of Regulations (CCR). Proposed amendments to sections 2180.1, 2181, 2184, 2185, 2186, 2192,
and 2194 of article 1, chapter 3.5, division 3, title 13, CCR.
What is ARB proposing?
The ARB staff is proposing to reduce air pollution by requiring owners and operators of trucks, school buses, and
motor homes with 1993-1998 model year heavy-duty diesel engines to upgrade the software in the electronic control
module (ECM) of these engines. Software upgrades were developed by the engine manufacturers and are available now
for most 1993-1998 model year engines. If adopted, owners and operators of eligible vehicles that operate in California
must ensure that their vehicles' engines have the appropriate low NOx software installed. Since many 1999 model
year vehicles have engines produced in 1998, owners and operators of 1999 model year vehicles will need to check
to determine if they are affected. Distributors and dealers must provide the appropriate low NOx software to the
vehicle owner or operator upon request.
What is a heavy-duty diesel engine software upgrade?
A heavy-duty diesel software upgrade (also referred to as low NOx software upgrade or chip reflash) is simply software
installed in the engine that reprograms the vehicle's computer and reduces off-cycle NOx emissions. The installation
process typically takes between one-half to one hour.
The ARB staff has prepared a list that can be checked to determine if low NOx software is available for the engine.
This list is available from our web site at: http://www.arb.ca.gov/msprog/hdsoftware/hdsoftware.htm
Would out-of-state vehicles be subject to the proposed requirements?
Yes. If adopted, owners and operators of 1993-1999 model year heavy-duty diesel vehicles (trucks, school buses,
and motor homes) registered out-of-state, but that travel within California, would also be required to ensure that
the engines in their vehicles have the appropriate low NOx software installed.
How much would the low NOx software installation cost?
The ARB staff believes the applicable Consent Decrees and Settlement Agreements require manufacturers to supply
the Low NOx software at no cost whenever it is requested. Out-of-service costs to the vehicle owner can be reduced
or eliminated if the low NOx software is installed at the same time as another service or repair.
When would low NOx software have to be installed?
If adopted by the Board, this regulation would require the low NOx software upgrade to be installed on a schedule
that depends on the model year of the engine in the affected vehicle. Our proposal is as follows:
|1993-1994 model years
||By April 30, 2005
|1995-1996 model years
||By August 31, 2005
|1997-1998 model years
||By December 31, 2005 (except for medium heavy-duty diesel engines (MHDDEs))
|1997-1998 model year
||MHDDEs By December 31, 2006
How would the low NOx software installations be enforced?
The ARB enforcement staff would verify the installations of the low NOx software through a modified Heavy-Duty
Vehicle Inspection Program and modified Heavy-Duty Vehicle Fleet Inspection Program.
How will I know if the regulation is adopted, and it is time to have the software installed?
If the Board adopts this proposed regulation and it becomes effective, the ARB staff will attempt to reach you
by mail with an alert stating that the regulation is effective and including the dates that low NOx software is
required to be installed in your engine. An informational notice would also be posted on the ARB website.

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
Pursuant to Government Code sections 11346.5(a)(5) and 11346.5(a)(6), the Executive Officer has determined that
the proposed regulatory action will not create costs or savings to any state agency or in federal funding to the
state, costs or mandate to any local agency or school district whether or not reimbursable by the state pursuant
to Part 7 (commencing with section 17500), Division 4, Title 2 of the Government Code, or other nondiscretionary
savings to state or local agencies.
In developing this regulatory proposal, the ARB staff evaluated the potential economic impacts on representative
private persons or businesses. There may be as many as 40,000 businesses, up to 3,000 school districts, and over
5,000 individuals who own motor homes with 1993-1999 model year heavy-duty diesel vehicles affected by this proposal.
Also affected are approximately 100 dealers/distributors for Caterpillar, Cummins, Detroit Diesel, Mack/Renault,
International (Navistar), or Volvo that have the capability to install low NOx software into an eligible engine's
ECM. Finally, this proposal will also affect the seven engine manufacturers mentioned already - each of which is
located outside of California. The total statewide costs that businesses and individuals may incur to comply with
this regulation over its lifetime are up to eight million dollars.
The ARB staff believes that the low NOx software should be provided and installed free of charge to vehicle owners
and operators. If engine manufacturers reimburse the dealers and distributors for labor charges, the only cost
to the vehicle owner would be the time that the vehicle is out-of-service. This includes time: 1) to drive the
vehicle to the dealer or distributor facility; 2) to install the low NOx software; and 3) to return the vehicle
back to service. Waiting time would be minimized if vehicle owners and operators make an appointment with the dealer
or distributor. This "time cost" can be reduced to next to nothing if the low NOx software is installed
at the same time that another service or repair is performed on the vehicle.
The Executive Officer has made an initial determination that the proposed regulatory action will 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 Code section 11346.3, the Executive Officer has determined that the proposed regulatory
action will 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 staff report (ISOR).
The Executive Officer has also determined, pursuant to Title 1, CCR, section 4, that the proposed regulatory action
will affect small businesses. Staff was unable to determine the number or percentage of total businesses impacted
that are small businesses. Staff believes that some of the approximately 40,000 companies (based on our mail-out)
that own 1993-1999 model year heavy-duty diesel vehicles affected by this proposal are small businesses based on
income, profit, number of employees, or number of vehicles owned. Some of the dealers/distributors affected may
also be small businesses. Staff has estimated the initial cost for a small business at 0-200 dollars (for time
out-of-service) with the typical business spending 0-1500 dollars to comply with this regulatory proposal.
In accordance with Government Code sections 11346.3(c) and 11346.5(a)(11), the ARB's 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 action, the Board must determine that no reasonable alternative
considered by the agency or that has otherwise been identified and brought to the attention of the agency 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.
