The Trump administration is returning to 2012 emission rules, which it says have cut mercury pollution by 90%. Environmentalists say that’s not enough.

Conservationists are warning that the Trump administration is working state by state to undo decades of progress in clearing skies over the country's beloved national parks. A federal regulation known as the regional haze rule established a goal of attaining natural visibility conditions in the parks by 2064.

The federal government said the coal plants were needed for “grid reliability” and a regional haze-fighting plan violated the Clean Air Act.

The new ‘dredge-and-fill’ rules address a gap by the U.S. Supreme Court’s Sackett decision two years ago, which drastically shrunk the number of waterways eligible for federal protections.

The narrowed pool of waters receiving federal protection under the rule could be severe for critical wetlands and streams in the arid West, many of which are seasonal or fed by groundwater.

Cyrus Western will implement the Trump administration’s environmental and energy agenda, overseeing extractive industries in Wyoming, Colorado, Utah, Montana, the Dakotas and 28 tribal nations.

So-called "forever chemicals" have been found in 29 water systems across Colorado. Fixing the problem could be costly for rural communities.

The Environmental Protection Agency is awarding the grants to 33 tribal nations and one U.S. territory. Recipients plan to apply the funding to reduce air pollution, transition to clean energy use, and promote environmental justice.

Air pollution can be two to five times worse indoors compared to outside, and it’s especially concerning for children, who tend to breathe in more air than adults in relation to their body weight.

Front Range gas prices are lower than a year ago despite requirement for “reformulated gas” that reduces ozone-causing emissions.
