Date: Mon, 25 Apr 2016 16:09:57 -0700 Subject: arbcombo -- Draft Truck and Bus Sector Description Released From: mmagtoto@arb.ca.gov The California Air Resources Board (ARB/Board) announces the release of the draft document “Supporting Information for Technology Assessments: Truck and Bus Sector Description”. ARB’s long-term objective is to transform the mobile source fleet into one utilizing zero and near-zero emission technologies to meet air quality and climate change goals. This document was prepared to support heavy-duty truck-related technology assessments heavy-duty fuel cell electric vehicles, hybrid electric vehicles, battery electric vehicles, and diesel and natural gas engines. It applies to Class 2b through Class 8 heavy-duty vehicles with greater than 8,500 pounds gross vehicle weight rating. It presents a description of the truck and bus sector including truck types, vocations, emissions, and economics of the trucking and truck and engine manufacturing industries. Sources used in the draft supporting information included published reports, research papers, and ARB inventory data. The draft supporting information for technology assessments can be viewed and downloaded from the ARB’s technology and fuels assessment webpage at: http://www.arb.ca.gov/msprog/tech/techreport/t&b_sector_description.pdf If you have questions regarding the draft supporting information, please contact the following: Mr. Inder Atwal, Air Pollution Specialist, at 916-445-0281, or at Inder.Atwal@arb.ca.gov. Background: California has made substantial progress in reducing emissions from mobile sources, but further reductions are needed to meet California’s air quality and climate goals. These goals include: •Meeting 2023 and 2031 ambient ozone air quality standards, which staff estimates will require an overall 80 percent reduction in NOx emissions below today’s levels in the South Coast air basin, with substantial reductions needed in the San Joaquin Valley and other non-attainment areas of the state as well; •Meeting the newly proposed federal ozone standard; •Reducing greenhouse gas (GHG) emissions to 1990 levels by 2020; •Achieving a 40 percent reduction in GHG emissions from 1990 levels by 2030; •Achieving an 80 percent reduction in GHG emissions from 1990 levels by 2050; •Reducing petroleum use in cars and trucks by up to 50 percent by 2030; and •Producing at least 50 percent of electricity from renewable sources by 2030. Heavy-duty vehicles greater than 8,500 pounds emit about one-fifth of the total GHG emissions associated with transportation sources in the State, which is about eight percent of the statewide total. In addition, these vehicles account for 33 percent of NOx emissions from all statewide sources. Because trucking emissions are such a significant source of GHG and criteria pollutant emissions, achieving reductions within the trucking sector is a key component in the strategy to meet California’s climate and air quality goals. The technology assessments were prepared by staff from ARB, along with the South Coast Air Quality Management District staff. They were discussed at workshops in September 2014 and at the December 2014 ARB board meeting. More information on the assessments is available at ARB’s website at http://www.arb.ca.gov/msprog/tech/tech.htm. Draft technology assessments reports were released for public comments and are available on ARB’s website at http://www.arb.ca.gov/msprog/tech/report.htm. California is in a drought emergency.

At this workshop, staff will be soliciting input on proposals to revise: • The heavy-duty engine NOx standards including a low load certification cycle; • The Not-to-Exceed in-use compliance program; • The useful life and durability requirements in certification; • Not to Exceed (NTE) In-Use Compliance Program; • Warranty period requirement; and • Emission Warranty Information Reporting The workshop is described further in the workshop notice at https://www.arb.ca.gov/msprog/mailouts/msc1610/msc1610.pdf and will be held at the following time and location: Date: Thursday, November 3, 2016 Time: 1:00 p.m. – 5:00 p.m. Location:South Coast Air Quality Management District, Auditorium 21865 Copley Drive Diamond Bar, California 91765 Directions are at http://tinyurl.com/ja4mxgk Background: A key measure described in ARB’s Mobile Source Strategy document is the establishment of national low-NOx emission standards that reflect up to a 90 percent reduction in NOx emissions compared to the current emission standards. This measure is critical for attaining federal health-based air quality standards for ozone in 2023 and 2031 in the South Coast and San Joaquin Valley air basins, as well as fine particulate matter standards in the next decade. A proposal for new low- NOx emission standards, associated revisions to the certification test cycle to account for low load urban driving conditions, and other potential revisions to account for real world emissions, is tentatively scheduled for Board consideration in 2019. In addition to lower NOx standards, other elements are being considered in an effort to improve the in-use performance of heavy-duty vehicles. Specifically, these elements are listed below followed by a more detailed discussion of each: • Amendments to warranty provisions. • Amendments to the NTE supplemental test procedures. • Amendments to the certification durability demonstration and useful life provisions. ARB is considering lengthening the required warranty period for heavy-duty vehicle emission control systems primarily because the warranty period does not reflect the real world longevity of heavy-duty vehicles. Class 8 vehicles frequently operate upwards of a million miles before major overhaul is needed, but they are required to be warranted for only 100,000 miles under ARB and U.S. EPA regulations. Classes 4 through 7 vehicles also have relatively short warranty periods. With longer required warranty periods, manufacturers would need to design more durable emission control systems and components. In addition to lengthening the warranty period, ARB also intends to strengthen and enhance the current Emission Warranty and Information Reporting requirements to more readily enact corrective action on the part of the manufacturer, based upon warranty rates. A proposal to revise both the warranty period and the warranty rates/corrective action requirements for heavy-duty vehicles is scheduled to be heard by the Board in December 2017. The NTE in-use compliance program is currently the primary method used for ensuring in-use compliance with the heavy-duty engine emission standards. The NTE testing requirements were first introduced as part of the 1998 Consent Decrees with U.S. EPA, ARB, and heavy-duty engine manufacturers. Manufacturers have to demonstrate compliance within the NTE control area of the engine map by measuring emissions using Portable Emissions Measurement Systems. However, the NTE control area includes a number of conditions that exclude regions in the engine map associated with low load operation, including the region below 30 percent maximum torque and/or 30 percent maximum power. Engine operations within the NTE control area for fewer than 30 consecutive seconds and engine operations that result in exhaust aftertreatment temperatures below 250 degrees Celsius are also excluded from the NTE analysis. Because of these current limitations, the current in-use compliance program is not adequate for ensuring that emissions are controlled during the majority of in-use operations, including low load conditions. ARB is currently considering modifying the testing protocol in order to effectively assess in-use compliance under essentially all driving conditions. ARB is also considering revising the durability demonstration provisions within the certification requirements for heavy-duty engines. The durability demonstration program requires manufacturers to demonstrate compliance with emission standards over the useful life of the engine. ARB staff are concerned that the current durability demonstration program does not accurately represent the in-use deterioration of aftertreatment emission control systems. Furthermore, the useful life over which compliance with the durability provisions is demonstrated is significantly lower than the full life or mileage before first rebuild, resulting in excess emissions due to deteriorated engines and components. Therefore, ARB is considering revising the useful life period as well, resulting in the need to revise the durability demonstration process to account for a longer useful life. Revisions to the NTE in-use compliance program, durability demonstration provisions, and the useful life period are all scheduled to be heard by the Board at the same time as the proposal for new low-NOx emission standards (i.e., 2019).

This workshop is described further in the workshop notice at https://www.arb.ca.gov/msprog/mailouts/mouts_16.htm. Date: Monday, February 6, 2017 Time: 9:30 a.m. to 4:30 p.m. Place: Cal/EPA Headquarters Building, Sierra Hearing Room 1001 I Street, Sacramento, California 95814 The workshop will also be available via webcast for stakeholders unable to attend in person and can be accessed at the following link on the day of the workshop: https://video.calepa.ca.gov/. For more information about the proposed California Phase 2 GHG standards, please go to: http://www.arb.ca.gov/msprog/onroad/caphase2ghg/caphase2ghg.htm. For the potential amendments to tractor-trailer GHG regulation, please go to: https://www.arb.ca.gov/listserv/listserv_ind.php?listname=hdghg. Contact: We welcome and encourage your participation in this workshop. If you have any questions regarding the proposed California Phase 2 or potential regulatory changes to Tractor-Trailer GHG Regulation, please contact Mr. Alex Santos, Staff Air Pollution Specialist, at (626) 575-6682 or by email at alex.santos@arb.ca.gov or Ms. Mitzi Magtoto, Air Resources Engineer, at (916) 323-8975 or by email at mitzi.magtoto@arb.ca.gov. Background: On October 25, 2016, the U.S. EPA published the final federal Phase 2 GHG standards. The federal Phase 2 standards are the second phase of federal heavy–duty GHG standards and build upon the federal Phase 1 standards. The federal Phase 2 standards will significantly reduce carbon emissions and dramatically improve the fuel economy for heavy-duty tractors, helping reduce emissions that cause climate change. They establish national GHG emission standards that will begin in model year 2021 for new class 2b to 8 medium- and heavy-duty engines and tractors, and in 2018 model year for certain trailer types. The federal Phase 2 standards will be fully phased in by model year 2027. On December 11, 2008, the Board approved the Tractor-Trailer GHG regulation codified in sections 95300-95312 of title 17, California Code of Regulations, and later amended in 2010 and 2014. This regulation required owners of 53-foot or longer box-type trailers and owners of the heavy-duty tractors that pull them on California highways to utilize U.S. EPA SmartWay verified or designated technologies that will reduce GHG emissions and improve fuel efficiency. In December 2013, ARB staff harmonized the tractor requirements of the Tractor-Trailer GHG regulation with the requirements of the Phase 1 standards.
