INFORMATIVE DIGEST OF PROPOSED ACTION AND POLICY STATEMENT OVERVIEW
Sections Affected: Proposed adoption of Chapter 10 - Mobile Source Operational Controls, Article 1- Motor Vehicles,
section 2485, title 13, California Code of Regulations (CCR).
Background
The Board identified diesel particulate matter (PM) as a toxic airborne contaminant (TAC) in August 1998. In September
2000, the Board adopted the "Risk Reduction Plan to Reduce Particulate Matter Emissions from Diesel-Fueled
Engines and Vehicles (DRRP)" which established a goal of reducing emissions and the resultant health risk
from virtually all diesel-fueled engines and vehicles in the state of California by the year 2020. The DRRP identified
various methods for reducing emissions of diesel PM including new, more stringent standards 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 diesel fuel.
The major sources of diesel-PM are the approximately 1,250,000 diesel-fueled engines in vehicles and equipment
used in California. Diesel exhaust from excessive idling imposes significant adverse health and environmental impacts
on all Californians. Diesel exhaust is a complex mixture of thousands of gases and fine particles that contains
more than 40 identified toxic air contaminants. These include many known or suspected cancer-causing substances,
such as benzene, arsenic and formaldehyde. Diesel exhaust can irritate the eyes, nose, throat, and lungs. It can
cause coughs, headaches, light-headedness, and nausea. Diesel exhaust is a major source of ambient particulate
matter pollution as well, and numerous studies have linked elevated particle levels in the air to increased hospital
admission, emergency room visits, asthma attacks, and premature deaths among those suffering from respiratory problems.
Human health and the environment are adversely affected by the air pollutants emitted by idling diesel-fueled engines.
An estimated 449 tons of diesel PM will be generated in California in 2004 from commercial motor vehicle idling.
Nitrogen oxides (NOx) emissions from idling are estimated to be nearly 19,878 tons per year. Because of the high
potency of diesel PM and the potential for large numbers of diesel-fueled engines to idle at one location (e.g.,truck
stops), staff believes that there are situations where the estimated 70-year potential cancer risk resulting from
exposure to diesel PM emissions will be in excess of 10 in a million.
ARB staff has prepared an Initial Statement of Reasons (ISOR) for the Proposed ATCM that, along with the DRRP,
serves as the report on the need and appropriate degree of regulation for reducing idling of diesel-fueled commercial
motor vehicles.
Description of the Proposed Regulatory Action
The Proposed ATCM to limit motor vehicle idling is designed to reduce the general public's exposure to diesel PM,
other TACs, and air pollutants. The Proposed ATCM would apply to diesel-fueled commercial motor vehicles with gross
vehicle weight ratings (GVWR) greater than 10,000 pounds operating in California, regardless of the state or country
in which the vehicle is registered.
The requirements of the Proposed ATCM would impact both the public and private transportation industries. Public
agencies that could be affected are transit agencies and public agencies with heavy-duty vehicles. Private businesses
that could be affected are private transit and tour bus operations, contractors, distributors, transporters, delivery
services, and heavy-duty vehicle fleets. Agencies and businesses would be affected to the extent they own, operate,
or direct the operation of buses and heavy-duty vehicles.
The Proposed ATCM would be implemented in two phases. Phase one eliminates general unnecessary idling and would
be implemented immediately upon approval of the Proposed ATCM into state law. The driver of a subject vehicle would
be required to manually shut off the engine before the idling time limit of five minutes is reached. Buses, including
transit, tour and coach, are not subject to the five minute idling restriction when passengers are on board and
are allowed no more than 10 minutes of idling time prior to boarding of passengers to allow the passenger compartment
adequate time to acclimate for passenger comfort.
Phase two of the Proposed ATCM would restrict idling of the main truck engine or diesel-fueled auxiliary power
system (APS) during driver rest periods and becomes effective January 1, 2009. Options to comply with the restricted
idling limitations would include shutting off the engine where weather conditions allow, off-board and on-board
electrification, and non diesel-fueled auxiliary power systems. ARB staff intends to return to the Board in 2005
to propose procedures and specifications under which diesel-fueled APS units would be allowed to operate beyond
January 1, 2009.
The Executive Officer has proposed circumstances under which exceptions to the Proposed ATCM's idle limits may
be determined necessary. Idling restrictions contained in the Proposed ATCM would not apply when idling is necessary
to prevent safety or health emergencies or when idling is necessary due to adverse weather conditions such as dense
fog. Idling limits would not apply when the vehicle is stopped in situations in which the driver has no control
such as being stopped at a traffic signal, railroad crossing, or construction zone. The Proposed ATCM's idle limitations
would not apply when idling is necessary during servicing, testing, vehicle inspections or when idling is necessary
to perform work for which the vehicle was designed such as turning a cement mixer. Additionally, the Executive
Officer has proposed that when vehicles are within 100 feet of designated restricted areas, owners/operators would
eliminate unnecessary cueing and extended driver rest period main engine idling; that is, they would remain subject
to phase one restrictions.
AVAILABILITY OF DOCUMENTS AND AGENCY CONTACT PERSONS
The Board staff has prepared a Staff Report: Initial Statement of Reasons for the Proposed ATCM, which includes
a summary of the potential environmental and economic impacts of the proposal. The ISOR is entitled, "Staff

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 ATCM are presented below.
Pursuant to Government Code section 11346.5(a)(5), the Executive Officer has determined that the Proposed ATCM
will not impose a mandate on local agencies or school districts. The Executive Officer has further determined pursuant
to Government Code section 11346.5(a)(6) that the Proposed ATCM will result in some additional costs to the ARB
and other state agencies. In addition, the Executive Officer has determined pursuant to Government Code section
11346.5(a)(6) that the Proposed ATCM will not create a cost to local agencies that are required to be reimbursed
under Part 7 (commencing with section 17500) of Division 4 of the Government Code or other non-discretionary costs
or savings imposed on local agencies or school districts. The Executive Officer further determined that the Proposed
ATCM would not result in costs or savings in federal funding to the State.
The Executive Officer has determined that the Proposed ATCM will have an insignificant impact on costs to local
agencies or school districts and will most likely result in cost savings. Cost savings will result from reduced
fuel and maintenance costs due to reduced idling and should offset any cost associated with driver compliance education.
Statewide, the total number of trucks equipped with sleeper berths owned or operated by local agencies and school
districts is not known, but is expected to be very small, if any. The cost impact to any local agency or school
district should therefore be very small.
Some minor costs will occur for state agencies that own and operate diesel-fueled commercial motor vehicles but
will most likely result in cost savings. Cost savings will result from reduced fuel and maintenance costs due to
reduced idling and should offset any cost associated with driver compliance education. Statewide, the total number
of trucks equipped with sleeper berths owned or operated by state agencies is not known, but is expected to be
small. Since these costs are insignificant compared to their overall budget, staff believes that the costs will
easily be met within existing budgets.
The Executive Officer has determined that the total cost for implementing the Proposed ATCM for state agencies
will be approximately $25,000 per year for outreach efforts in 2003 expenditure equivalent dollars. While the ARB
is expected to absorb enforcement activities within current budgets and with current staff for the foreseeable
future, if monies become available, an additional 12 person years could be required for enforcement. Initial outlay
will not be necessary until fiscal year 2005-2006. The affected state agencies are ARB, California Highway Patrol,
and potentially other state law enforcement agencies. It is anticipated that the agencies will be able to absorb
costs, given the extended period allowed for compliance.
In developing this regulatory proposal, the ARB staff evaluated the potential economic impacts on representative
private persons or businesses. The ARB is not aware of any cost impacts that a representative private person or
business would necessarily incur in reasonable compliance with the proposed action.
The Executive Officer has made an initial determination that the Proposed ATCM 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.
The Executive Officer has determined, pursuant to title 1, CCR, section 4, that the Proposed ATCM will have a positive
cost-savings impact on small businesses. The ARB staff believes that nearly 73 percent of affected businesses are
small businesses.
The Executive Officer has determined that the total cost savings of the Proposed ATCM to affected businesses will
be approximately $575 million for both cost/benefit analysis windows (phase one 2005 - 2009 and phase two 2009
- 2013), in 2003 equivalent dollars. This value represents the total cost savings of the Proposed ATCM if all money
required to comply and all monetary benefits were spent or generated today. On an annual basis, the cost savings
will vary between $17 to greater than $113 million per year. The cost savings for a typical business, including
capital costs, is estimated to be up to $425 per vehicle per year in 2003 equivalent dollars. Additionally, owners
and operators are expected to enjoy cost savings outside of the cost/benefit analysis windows for the lifetime
of the regulation. The ARB staff estimates that the annual cost savings, including capital costs, to a typical
small business (a fleet of seven or less vehicles) will be up to $425 per vehicle per year in 2003 equivalent dollars.
In accordance with Government Code sections 11346.3 and 11346.5(a)(10), the Executive Officer has determined that
the Proposed ATCM may lead to creation or elimination of some businesses, 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. The Proposed ATCM could create a demand in manufacturing and services of automotive
diesel idle reduction technologies. The Proposed ATCM could also have a positive impact on the creation and expansion
of jobs and businesses, especially for companies engaged in the engineering, design, and manufacture of auxiliary
power systems. In the service sector, the Proposed ATCM could positively impact job creation at locations that
choose to provide on- and off-board truck stop electrification services.
A detailed assessment of the economic impacts can be found in the ISOR.
CONSIDERATION OF ALTERNATIVES
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 or businesses than the proposed action.
SUBMITTAL OF COMMENTS
The public may present comments relating to this matter orally or in writing at the hearing and in writing or by
e-mail before the hearing. To be considered by the Board, written submissions not physically submitted at the hearing
must be received no later than 12:00 noon, July 21, 2004, and addressed to the following:
Postal mail is to be sent to:
