The California Air Resources Board (CARB or Board) will conduct a public
hearing at the time and place noted below to consider approving for
adoption the proposed amendments to the California
emission control system warranty regulations and maintenance provisions for
on-road heavy-duty diesel vehicles with gross vehicle weight ratings greater
than 14,000 pounds and heavy-duty diesel engines in such vehicles.
DATE: June 28, 2018
TIME: 9:00 a.m.
LOCATION: California Environmental Protection Agency
California Air Resources Board | Coastal Hearing Room
1001 I Street
Sacramento, California 95814
This
item will be considered at a meeting of the Board, which will commence
at 9:00 a.m., June 28, 2018, and may continue at 8:30 a.m., on June 29, 2018. Please consult the agenda for the hearing, which will be
available at least ten days before June 28, 2018, to determine the day
on which this item will be considered.
Background
A key measure in CARB’s 2016 State Strategy for the State Implementation Plan is ensuring that heavy-duty vehicles, and the engines that power them, operate in use at their cleanest possible level (the “Lower In-Use Emission Performance Level” measure). Amendments to the on-road heavy-duty warranty provisions are an important part of that measure, and would contribute to attaining federal health-based air quality standards for ozone in 2023 and 2031, in both the South Coast and San Joaquin Valley air basins. Staff is proposing to amend the California on-road heavy-duty vehicle and heavy-duty engine warranty regulations to lengthen both the existing emissions control system warranty periods and minimum maintenance intervals to better reflect the longevity and usage of modern vehicles. Lengthening the warranty period would reduce emissions by incentivizing the repair of malfunctioning emissions-related parts and potentially encouraging manufacturers to make parts more durable. In addition, lengthening the regulatory-specified minimum maintenance intervals would help limit manufacturers’ ability to transfer the liability for part replacements to vehicle owners for emissions-related parts during the lengthened warranty periods, further strengthening warranty coverage. Also, staff is proposing a few regulatory clarifications including an amendment of the “General Emissions Warranty Coverage” applicability provisions to include any part that causes the illumination of the heavy-duty on-board diagnostics system’s malfunction indicator light. The proposed warranty amendments would achieve a 0.75 tons per day reduction in statewide oxides of nitrogen by 2030, as well as a small reduction in particulate matter emissions.
