Medium- and heavy-duty vehicles (MHDVs), like the big rigs on our highways and the vans that deliver our packages, make up just over 1 in 10 of the vehicles on our roads, but are responsible for over half of ozone-forming nitrogen oxide pollution and lung-damaging fine particulate pollution from on-road vehicles.

The WAIRE Program essentially requires warehouse operators to take actions to electrify warehouse activities and the trucks that visit warehouses in order to reduce nitrogen oxides (NOx) and diesel particulate matter (DPM) emissions. Areas that are in “nonattainment” are subject to additional requirements (e.g., Further Actions.

The Basin does not meet the state or federal ambient air quality standards for ozone and particulate matter, and existing regulations have to date proved insufficient to bring the Basin into compliance. The SCAQMD is requesting stakeholder feedback on the discussion draft rule by December 6, 2019. 20, 2019). [6] Looking Forward.

The state funded the two studies through the 2019 Budget Act. Particulate matter harms lungs and hearts, while nitrogen oxide compounds contribute to ozone pollution and other health impacts. A second study led by UC Santa Barbara was released simultaneously.

Examples are benzene, hydrofluoric acid, particulate matter, sulfur dioxide, nitrogen oxides, and many, many other toxic pollutants. One good example of the nexus between global warming and local pollution is ground-level ozone. To make matters worse, NOx contributes to the formation of ground-level ozone and secondary PM2.5,
