The American Lung Association’s State of the Air report measures three of the major types of pollutants in the San Joaquin Valley: long-term particle matter, short-term particle matter, and ozone. come from reactions of industrial pollutants (nitrogen oxides and sulfur oxides) with sunlight and unfinished fuel combustion.

California’s leadership on reducing truck pollution has been on full display the past few years, passing critical regulations requiring 90 percent reduction in smog-forming nitrogen oxide (NO X ) emissions from diesel trucks and requiring manufacturers sell an increasing share of electric trucks to move away from fossil fuels altogether.

By advancing Pennsylvania’s clean transportation infrastructure, we reduce harmful emissions of nitrous oxides and sulfur dioxide across Pennsylvania. Replacing heavy diesel vehicles with new low- to zero-emissions equipment technology will help mitigate air pollution from transportation sources.”

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. Annually, the project will remove 1.38 Annually the project will remove 3.9 tons of NOx and other pollutants from the air.

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.

The types of projects eligible under the CPP range widely, but notably the agency is focused on already proven zero-emission technologies, like electric tractor trucks, tugboats, and cargo handling equipment. The program is squarely focused on zero-emission equipment and projects – combustion technologies are explicitly ineligible.

The locomotives at issue in this settlement burn diesel fuel which produces significant emissions of nitrogen oxides (NOx) and fine particulate matter. NOx is a contributor to the formation of summer ozone, and particulate matter smaller than 2.5 microns has been shown to cause lung damage and cancer.
