arbcombo -- Now Available: ARB’s comments on EPA/NHTSA Proposed Rulemaking for Phase 2 GHG Standards for Medium- and Heavy-Duty Engines/Vehicles
Posted: 02 Oct 2015 09:33:35
On October 1, 2015, the Air Resources Board (ARB) submitted its formal comments to the public dockets of both the U.S. Environmental Protection Agency (U.S. EPA) and the National Highway Traffic Safety Administration (NHTSA) on their joint proposal for Phase 2 of the federal greenhouse gas (GHG) and fuel efficiency standards for medium- and heavy-duty engines, vehicles, and trailers. The comments, along with a letter signed by ARB’s Chair Mary D. Nichols summarizing ARB’s most significant concerns and recommendations for accelerating and strengthening the federal Phase 2 program, are now available at: http://www.arb.ca.gov/msprog/onroad/caphase2ghg/caphase2ghg.htm Overall, ARB believes the proposed federal Phase 2 program is a good next step in supporting California’s actions to achieve unique climate and petroleum reduction goals. However, ARB also believes the proposal misses opportunities to maximize GHG emission reductions and spur development of critical advanced technologies that can provide early climate benefits; these advanced technologies are especially important to California in meeting our 2030 GHG and petroleum use reduction goals. Additionally, the proposal did not include a commitment from U.S. EPA to begin development on lower, mandatory oxides of nitrogen(NOx)emission standards for heavy-duty engines and vehicles, as was expected by ARB. California needs dramatic further reductions in NOx emissions beyond what ARB’s current programs will achieve by 2031 to attain health-based standards for ozone and fine particulate matter. ARB will move forward with its efforts to establish a California-only lower NOx standard if U.S. EPA does not take timely federal action. ARB has also submitted separate comments in response to NHTSA’s Draft Environmental Impact Statement, which analyzes potential environmental impacts of the proposed fuel efficiency standards in the Phase 2 rulemaking and is prepared pursuant to National Environmental Policy Act requirements. This comment letter is also available from the website shown above.

Background: ARB staff has worked jointly with the staff of U.S. EPA and NHTSA on the next phase of GHG emission standards, referred to as Phase 2, for medium- and heavy-duty engines and vehicles. The proposed standards build on the improvements in engine and vehicle efficiency required by the Phase 1 GHG standards, and provide a significant opportunity to achieve further GHG emission reductions from a wide range of on-road vehicles---from semi-trucks and their trailers, large pick-ups and vans, vocational work trucks, and buses. U.S. EPA and NHTSA issued their final joint Notice of Proposed Rulemaking for the Phase 2 GHG and fuel efficiency standards on July 13, 2015. The joint federal proposed rules and related documents are available from both agencies’ websites shown below. http://www3.epa.gov/otaq/climate/regs-heavy-duty.htm http://www.nhtsa.gov/fuel-economy Upon federal adoption of the Phase 2 standards, ARB staff plans to present a proposed California Phase 2 program to the Board tentatively in 2017.
