New study explains wintertime ozone pollution in Utah oil and gas fields

Chemicals released into the air by oil and gas exploration, extraction and related activities can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards, according to new NOAA-led research, published online Nature. CPO's AC-4 program supported this research.

The study comes at a time when new technologies are helping to accelerate oil and gas development in Utah’s Uintah Basin, elsewhere in the United States and in many other countries, and its findings may help air quality managers determine how to best minimize the impact of ozone pollution.

The research is based on data collected in a series of wintertime studies in Uintah Basin led by James Roberts, of NOAA’s ESRL. Researchers from NOAA, CIRES, and other institutions made detailed measurements of ozone and the chemical ingredients, such as VOCs and nitrogen oxides, that “cook up” into the pollutant, and they used chemical models to better understand the chemistry behind the wintertime ozone formation.

ABOUT OUR ORGANIZATION

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2011, the United States experienced a record high number (14) of climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 670 lives, caused more than 6,000 injuries, and cost $55 billion in damages. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
