The EPA is getting ready to finalize a critical regulation limiting emissions of smog-forming nitrogen oxide (NO X ) and soot (or particulate matter, PM 2.5 ) from new heavy-duty trucks. do we really get a “90 percent reduction in NO X ” just because the test procedure requirement drops from 0.2 Test cycles in the real world.

Environmental Protection Agency emissions tests. By replacing older polluting engines and equipment with new technologies, funded projects remove nitrogen oxide, carbon monoxide, particulate matter, and hydrocarbon pollution from the air. On September 30, the Department of Environmental Protection announced $2.9

and nitrogen oxides (NOx) from the numerous commercial and government fleets of MHD vehicles in the state. The ACF is an opportunity to deliver meaningful reductions in air pollution for the most affected communities, but the current proposal falls short of what is technologically and economically feasible.

States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards ( NAAQS ) set by the U.S. and Sierra Club v.

As such, the agency has set emissions standards for particulate matter (soot, or PM), smog-forming emissions like nitrogen oxides (NO x ) and volatile organic compounds (VOCs), and heat-trapping emissions like carbon dioxide (CO 2 ), methane (CH 4 ), and hydrofluorocarbons (HFCs) commonly found in air-conditioning systems.

Also on the agenda is a final regulation setting RACT (Reasonably Available Control Technology Standards) for major sources of nitrogen oxides. Local government groups, drinking water suppliers and many other groups opposed the last minute amendment, which Republican legislators ignored.

However, automakers are pushing to weaken the stringency and test requirements of the proposal sufficiently such that this common-sense emissions-reducing technology remains on the shelf in the U.S. In 2040, even including relevant technology and charger costs, Alt 1+ would save drivers $86 billion—that’s $24 billion more than Alt 3.
