A chemical plant in Cheyenne was cited by the federal government for violating safety standards.

New research shows that intense wildfires can leave behind dangerous levels of carcinogenic hexavalent chromium in soil and ash, close enough to the surface that wind could easily carry it away.
-
A new study finds that wildfires are having a major impact on trends in fine particulate pollution and their health impacts, especially in the American West. The researchers found that fire emissions have reversed pollution gains made in our region, and that premature deaths associated with such pollution are up by nearly 700 annually.

Wyoming has a new way for testing emissions related to oil and gas production, and the state won an award for it.

One consequence of human-caused climate change is that warm temperatures are persisting into the fall. Among other things, that means that plants have more time to produce and release pollen that irritates millions of allergy sufferers across the country. A recent report from Climate Central found that the freeze-free growing season for ragweed has grown by an average of 11 days since 1970 in some 160 cities.

Wyoming’s plan for managing pollution from some of its coal plants is okay for now, due to a recent court ruling. While the state sees this as a win, environmental groups are concerned.
-
Thousands of Americans are dying prematurely because of pollution from oil and gas, according to a new study from four health and environmental advocacy groups, those include Boston University, University of North Carolina, the Environmental Defense Fund (EFD) and Physicians, Scientists and Engineers for Health Energy.

Some Laramie County residents recently submitted a letter to the state, requesting that an air quality monitor be moved to better reflect the air they are breathing in.

One can see hundreds of homes all on a couple acres of prairie, and mixed in with these houses is oil and gas development. Driving through one passes a home and then a couple pump jacks, and then past another home one sees a drilling rig. Oil and gas activity significantly picked up in Laramie County about 10 years ago, and in the years since, it has moved into residential areas. The Cheyenne Area Landowners Coalition advocates for residents that are concerned about this development.
