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 The broadcast can be accessed on the day of the workshop at: https://video.calepa.ca.gov/. The presentation slides for the May 17, 2017, workshop may be accessed on the website at: https://www.arb.ca.gov/msprog/hdim/meetings/opacity_workshop_presentation_05-17-2017.pdf For more information and to view the public workshop notice, please visit the program website at: http://www.arb.ca.gov/msprog/hdim/hdim.htm. If you wish to continue to receive information regarding the potential opacity regulatory amendments or the HD I/M regulatory development process, please sign up for the new HD I/M list serve: http://www.arb.ca.gov/listserv/listserv_ind.php?listname=hdim. For more information on the existing HDVIP and PSIP, please visit the program website at: http://www.arb.ca.gov/enf/hdvip/hdvip.htm 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.
