arbcombo -- PRESENTATION POSTED FOR 5/17/2017 PUBLIC WORKSHOP ON POTENTIAL CHANGES TO THE HEAVY-DUTY VEHICLE/ PERIODIC SMOKE INSPECTION PROGRAMS

Posted: 17 May 2017 07:36:22
The California Air Resources Board (CARB or Board) invites you to
participate in a public workshop to discuss proposed regulatory
amendments to CARBís Heavy-Duty Vehicle Inspection Program
(HDVIP) and the Periodic Smoke Inspection Program (PSIP).   Staff
will discuss proposed amendments that would: 1) reduce the
current 40 percent opacity limit; 2) require opacity testers to
be trained to ensure compliance with the SAE J1667 snap
acceleration test procedures; and 3) require web-based fleet
reporting.  Staff also will briefly discuss its ongoing efforts
to develop a comprehensive inspection and maintenance (I/M)
program for heavy-duty (HD) vehicles with a gross vehicle weight
rating over 14,000 pounds for implementation in the post-2020
timeframe.

The workshop will be held at the following location and time, and
will be webcast for those unable to attend in person.  This is
the third public workshop, and staff is scheduled to present the
proposed amendments to the Board at the October 26-27, 2017,
public meeting in Riverside, California.

Date:		Wednesday, May 17, 2017
Time:		1:30 p.m. Ė 4:30 p.m.
Location:	CalEPA Headquarters Building
		Sierra Hearing Room, 2nd floor
		1001 I Street
		Sacramento, California 95814

Background:
Legislative mandates from the late 1980s and early 1990s required
CARB to develop regulatory programs to inspect heavy-duty
vehicles for excessive smoke emissions and for tampering.  These
programs, the HDVIP (also known as the roadside program) and the
PSIP (also known as the fleet program), remain in force today and
are currently CARBís primary HD vehicle screening programs to
detect excess opacity emissions from in-use trucks.  While these
programs have been effective, they were established before the
use of diesel particulate filters (DPFs), which come new on 2007
and later model year engines.  Because of the widespread use of
DPFs and the need to ensure they are operating efficiently, CARB
now needs to update the HDVIP and PSIP regulations to reduce the
opacity limit to assist in identifying heavy-duty trucks with
broken DPFs and in need of repair, and to incorporate other
proposed program improvements.

The proposed amendments to the HDVIP and PSIP are also an
important first step in transitioning to a more robust
multi-pollutant HD I/M program that takes advantage of the
extensive capabilities of on-board diagnostic systems in newer
engines (2013 and later model year engines) for monitoring the
performance of nearly every emission-related engine component and
emission control component.  At the workshop, staff will also
briefly present its ongoing work in developing a comprehensive HD
I/M regulatory program, which it expects to present to the Board
for consideration in the 2020-timeframe.
