INFORMATIVE DIGEST OF PROPOSED ACTION AND POLICY STATEMENT OVERVIEW
Sections Affected: Proposed adoption of new sections 2700-2710, chapter 14, title 13, California Code of Regulations
("CCR") and the procedures incorporated by reference therein. The following American Society for Testing
and Materials methods for measuring fuel properties are incorporated herein by reference: D5453-93, D5186-96, D4629-96,
D613-84, D287-82, D445-83, D93-80, and
In 1998 the ARB identified diesel particulate matter emissions from diesel-fueled engines as a toxic air contaminant
(title 17 CCR Section 93000). The ARB adopted the Diesel Risk Reduction Plan ("DRRP" or "Plan")
in 2000 which establishes a goal of reducing emissions in virtually all in-use diesel engines within the State
of California by the year 2010. This Plan envisions that particulate emissions from diesel-fueled engines ("diesel
particulate matter") should be reduced by 85 percent or to 0.01 grams per brake horsepower-hour. The ARB is
reviewing various methods under review for achieving the goals in the Plan including new, more stringent standards
for all new diesel-fueled engines and vehicles, the use of diesel emission control strategies, and the use of low
sulfur diesel fuel. After the ARB adopted the DRRP, it became apparent that a method of evaluating diesel emission
control strategy systems would be needed. Towards this end, staff has developed a verification procedure, warranty
and in-use compliance requirements which could be used to verify reductions of diesel particulate matter and/or
oxides of nitrogen ("NOx") from in-use diesel engines using a particular emission control strategy, when
and if such strategies are required in future regulations. At this time, however, use of the proposed verification
procedure, warranty and in-use compliance requirements would be totally voluntary.
At the May 16, 2002 hearing, staff will present the verification procedure, warranty, and in-use compliance requirements.
This procedure will specify the information that manufacturers would submit to the ARB to verify their diesel emission
control strategies. The verification procedure for in-use strategies to control emissions from diesel engines is
designed to ensure that emission reductions derived from the use of these strategies are both real and durable.
To verify a diesel emission control strategy, the applicant would perform emission reduction testing, conduct a
durability demonstration, conduct a field demonstration, and submit the results along with other information in
an application to ARB following a prescribed format. Prior to performing any testing, the applicant would submit
a proposed verification testing protocol and have it approved by ARB. If, after reviewing the application, ARB
verifies the diesel emission control strategy, it would issue an Executive Order to the applicant describing the
verified emission reduction and any conditions that must be met for the diesel emission control strategy to function
properly. The applicant would also provide a warranty to the end-user and conduct in-use compliance testing.
COMPARABLE FEDERAL REGULATIONS
The U.S. Environmental Protection Agency (U.S. EPA) has published a draft document, "General Verification
Protocol for Diesel Exhaust Catalysts, Particulate Filters, and Engine Modification Control Technologies for Highway
and Nonroad Use Diesel Engines," but has not promulgated formal regulations for this verification protocol.
This verification protocol is intended to support the voluntary retrofit programs initiated by the U.S. EPA, while
the staff's proposal is to support the ARB's Diesel Risk Reduction Plan.
AVAILABILITY OF DOCUMENTS AND AGENCY CONTACT PERSONS
The ARB staff has prepared a Staff Report: Initial Statement of Reasons (ISOR) for the proposed regulatory action
that includes a summary of the environmental and economic impacts of the proposal.
Copies of the Staff Report and the full text of the proposed regulatory language may be accessed on the ARB's web
site listed below, or may be obtained from the ARBs Public Information Office, Environmental Services Center, 1001
"I" Street, First Floor, Sacramento, CA 95814, (916) 322-2990 at least 45 day prior to the scheduled
hearing (May 16, 2002).
Upon its completion, the Final Statement of Reasons (FSOR) will also be available and copies may be requested from
the agency contact persons in this notice, or may be accessed on the web site listed below.

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 in reasonable
compliance with the proposed regulations are presented below.
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 non-discretionary
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. 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 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 businesses directly affected.
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 California, or the expansion of businesses currently doing
business within California. An assessment of the economic impacts of the proposed regulatory action can be found
in the Staff Report.
The Executive Officer has also determined, pursuant to Government code section 11346.5(a)(3)(B), that the proposed
regulatory action will not affect small businesses because participation in the procedure is purely voluntary with
respect to any businesses. There are no cost impacts that a representative private person or business would necessarily
incur in reasonable compliance with the proposed action.
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 alternative considered
by 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.
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 must be received by no later than
