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,

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. According to the 2016 AQMP, mobile sources contributed about 88% of total NO x emissions in the Basin in 2012.

This proposed analysis includes the impacts of nitrogen oxides and volatile organic compounds from the wildfire in Quebec, Canada on June 6 to June 8, 2023 and June 28 to July 1, 2023. The impacts from the 2023 Canadian wildfires had significant impacts on air quality in 2023. Click Here for a copy of the analysis.

Air Pollution Air pollutants such as carbon monoxide (CO), hydrogen sulfide (H2S), nitrogen oxides (NOx), particulate matter (PM), and volatile organic compounds (VOCs) are released from various stages of shale gas development. NOx and VOCs mix in the presence of sunlight to form ground level ozone (smog).
