CARB Passes Amendments to Commercial Harbor Craft Regulations

SACRAMENTO – The California Air Resources Board today approved updates to its Commercial Harbor Craft Regulations aimed at reducing emissions from harbor craft such as tugs and ferries operating near the California coast to improve health service in nearby communities, many of which are disadvantaged.

By 2035, the modifications are expected to result in an 89% reduction in diesel soot (also known as particulate matter) and a 54% reduction in nitrogen oxides. The changes will also reduce the risk of cancer for more than 22 million people who live near the coast and up to 50 miles inland.

“Emissions from harbor craft contribute to toxic diesel emissions from coastal and harbor activities,” said CARB Chair Liane Randolph. “These changes will help clean the air and protect public health, especially in communities adjacent to the port that are already burdened by high levels of air pollution.”

Marine engines are regulated, with Tier 1 being the oldest emission standard and Tier 4 being the newest and least polluting standard. CARB offers a cleaner performance standard than Tier 4. Most harbor boats use older engine technology, such as Tier 2 engines, which release 162 times more diesel particulates than a five-year-old school bus . With today’s changes, the reduction in diesel soot achieved by 2038 is equivalent to eliminating 246,000 heavy-duty diesel trucks traveling from Los Angeles to Sacramento every day for one year.

Current commercial harbor vessel regulations have accelerated the move to Tier 2 and 3 engines for certain categories from 2009 until 2022; the new modifications will require zero-emission options where possible, and cleaner-burning Tier 3 and Tier 4 engines on all other ships. Additionally, they will require the use of diesel particulate filters, which are standard equipment on new cars and trucks. Short-term ferries, which include those traveling less than three nautical miles in a single trip, must be fully zero-emissions by the end of 2025. whale watching or dinner parties are also required. be able to operate with at least 30% power from a zero-emission source.

Approved changes include, for all vessel categories, compliance flexibilities such as fleet averaging or additional compliance time on other vessels in a fleet if a zero emissions vessel is deployed where applicable. possible but not required.

The amendments affect all classes of commercial harbor craft and establish the first emission standards for commercial fishing passenger vessels, pilot vessels, tank barges over 400 feet, workboats and vessels of research. These vessels are required to use cleaner engine fuel to reduce emissions under current regulations, but they were not required to switch to cleaner engines before. CARB held hundreds of public meetings, several public workshops, reviewed stakeholder feedback, and conducted site visits to craft the amendments.

Today’s changes will begin to be phased in from 2023 until the end of 2032. Following stakeholder feedback, CARB has incorporated compliance extensions for certain classes of vessels that would not have not to be upgraded before the end of 2034 if the shipowner requests and receives an extension if a replacement ship is needed but cannot be paid for. To address concerns raised by the sport fishing industry, the Board approved changes recommended by staff that provide a one-time ten-year extension option for commercial fishing passenger vessels until 2035 if a vessel is equipped with all Tier 3 engines by the end of 2024. This change will provide more certainty for ship owners, as well as at lower cost without the need to renew extensions every two years.

In addition, the Board directed staff to establish a Technical Working Group and provide updates to the Board every two years beginning in 2024. Updates would include the status of craft technology commercial ports that staff would use to explore future possibilities for adopting stricter zero standards. – emission requirements in the future. Additionally, the Board directed staff to continue to engage with the sport fishing industry and conduct a review of technology available to sport fishing vessels by 2028.

Incentive funding opportunities are available for operators, especially those taking early action or taking action beyond what is required by regulation. Funding opportunities may exist through the Carl Moyer Program, Community Clean Air Incentives, the Volkswagen Environmental Mitigation Trust, and other opportunities such as the Low Program-funded Advanced Technology Demonstration and Pilot Projects program.
