WASHINGTON (Reuters) - The U.S.
Environmental Protection Agency will announce plans to propose new rules
to significantly decrease emissions of smog-forming nitrogen oxide from
diesel-powered heavy-duty trucks, an agency official said.
Industry groups and state environmental officials have urged the EPA to
set new nationwide rules as the state of California has been moving
forward with plans to set new state emissions limits. California also
wants nationwide rules, in part because more than half of all trucks
delivering goods in the state are registered in other states.
The EPA said in a statement it had scheduled a formal announcement on
Tuesday with industry executives and state environmental officials
regarding its "Cleaner Trucks Initiative," but did not immediately
disclose details. The effort to impose a new regulatory limit by the EPA
comes as the Trump administration has generally touted its efforts to
eliminate regulations. But the effort on nitrogen oxide (NOx) is backed
by industry, which wants to avoid a patchwork of federal and state
standards, the official said.
The official asked not to be identified because the announcement was
In December 2016, the Obama-led EPA said in response to petitions to
impose new standards that it acknowledged "a need for additional NOx
reductions from on-highway heavy-duty engines, particularly in areas of
the country with elevated levels of air pollution" and said it planned
to propose new rules that could begin in the 2024 model year.
Local and state air quality and other agencies including New York City,
New Hampshire, Rhode Island, Los Angeles, Washington State had
petitioned for the rules.

Another administration official said Monday the new proposed
emissions rules may not be written and announced until 2020.
Nitrogen oxide emissions are linked to significant health impacts
and can exacerbate asthma attacks, the EPA has said.
The current heavy-duty truck rules for NOx were adopted in 2000 and
took effect over the following decade.
In the aftermath of Volkswagen AG's <VOWG_p.DE> light-duty diesel
emissions scandal, in which the German automaker admitted to
secretly using software to evade emissions rules, the EPA has taken
steps to insure that diesel cars and SUVs are meeting emissions
requirements in on-road use.
The new NOx heavy-duty truck rules may also include new tests or
other regulatory steps to ensure that vehicles and their engines are
complying during real-world driving, the official said.
