MassDEP files new regulations to reduce emissions, advance market for clean trucks

BOSTON, Mass. (WLNE)- The Massachusetts Department of Environmental Protection announced emergency regulations have been filed with the Secretary of the Commonwealth’s office to immediately adopt California’s Advance Clean Trucks regulation.

The regulation requires an increasing percentage of zero-emission vehicles truck sales from Model Year 2025 to 2035. MassDEP hopes to further reduce transportation emissions of nitrogen oxides, toxic air contaminants, and greenhouse gases fro on-road vehicles, as well as accelerating the adoption of zero-emission vehicles.

“Massachusetts continues to take aggressive action to reduce emissions from the transportation sector, and addressing pollution from medium- and heavy-duty vehicles and advancing the market for clean trucks is an essential part of this effort,” said Energy and Environmental Affairs Secretary Kathleen Theoharides. “Reducing emissions from trucks will help support public health by improving air quality, reducing the risk from exposure to toxic diesel pollution, and reducing emissions that contribute to climate change.”

“The transportation sector accounts for about 40 percent of the total greenhouse gas emissions statewide. Adopting California’s regulations will help to reduce air pollution across the Commonwealth and protect our environment and the public health,” said MassDEP Commissioner Martin Suuberg. “Adoption of these rules will also address environmental justice concerns in communities that are disproportionately impacted by medium- and heavy-duty vehicle traffic.”

According to MassDEP,

“Massachusetts law requires the Commonwealth to adopt California motor vehicle emissions standards as long as those standards achieve, in the aggregate, greater emissions reductions than federal standards. Massachusetts first adopted the California Low Emission Vehicle (LEV) program regulations in 1991 and has amended it many times to remain identical to the California LEV program. This latest amendment involves emission standards for Model Years 2025 and later medium- and heavy-duty vehicles and engines.”

There will be public comment available for those who wish to speak on the new requirements.

“Today’s filing begins a three-month process towards making the emergency regulations permanent, which will include a public hearing on the amendment set for January 21, 2022, and a 30-day public comment period which ends on January 31, 2022.

MassDEP projects these measures to benefit Massachusetts in the following ways:

  • Health benefits of $363 to $818 million from avoided premature deaths, hospitalizations for cardiovascular and respiratory illness, and emergency room visits.
  • Regional medium- and heavy-duty vehicle emission reductions of 51 percent for nitrogen oxides, 23 percent for particulate matter, and 53 percent for GHG, compared with today’s emission levels.
