Since 2014 CASAC has consistently recommended that the ozone primary standard be lowered from the current standard of 70 parts per billion (ppb) to 60 ppb, but the 2024 EPA rule did not make the standard stricter. These are the criteria air pollutants, namely PM 2.5 , ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide and lead.

The power outage led to the death of six people in Spain who died of carbon monoxide poisoning from a faulty backup generator, and one person in Portugal whose mechanical ventilator ran out of battery charge before emergency services arrived. Hospitals switched to backup generators in order to continue treating patients.

Beaver County Marcellus Awareness Community sent a letter to DEP on March 21, 2014 requesting that once they receive Shell’s application it should be posted on DEP’s website so that the community has ample time for review. BCMAC will also ask that a public hearing be held to allow sufficient time for public comment.

Fossil fuel combustion produces carbon dioxide (CO2), the most abundant global warming pollutant, but also produces local pollutants such as fine particulate matter (PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and volatile organic compounds (VOCs).

However, leaks which allow gasses to escape can mitigate reductions or result in overall increases in emissions relative to alternate storage methods, and generating energy via anaerobic digesters can emit pollutants like nitrogen oxide and carbon monoxide, among others. 2014 , Moeletsi and Tongwane, 2015 , Kritee et al.,

In general, environmental data are organized according to media, such as air or groundwater, analytical fraction, such as VOCs, and sampling round, such as 2014 data. For example EPA Method 8021 is for VOCs under RCRA, one list, but EPA Method 524 is for “purgeable” organic compounds in drinking water, same concept but different lists.
