Trump administration continues to undermine Colorado’s efforts to turn the page on coal

See how well you understand what the Trump administration is up to

Mychal Ozaeta, Attorney, Clean Energy Program: “These 13 are the most dangerous coal ash ponds in the U.S. because they’re leaking. They’ve been doing so for decades.”

Abigail Dillen, President of Earthjustice: “They’ve projected that they’re going to do a lot of this stuff. They’re not getting to the point of finalizing or even taking final action that’s actually in the courts yet.”

EPA issues rule to allow ongoing release of toxic chemicals into sources of drinking water for more than 30 million Americans

Exemptions for toxic coke oven facilities leave communities vulnerable to harmful air pollutants

Jonathan Kalmuss-Katz, Attorney, Toxic Exposure & Health Program, Earthjustice: “When you have chemicals that are this ubiquitous and this toxic, they really call out for strong regulations. You really need the government to do its job and provide protections.”

106 groups oppose EPA abandoning its defense of national health-protective pollution standards for fine particulate matter, also known as PM2.5 or soot.

A February 2026 deadline calls for EPA to address air pollution from soot, but it appears the agency has taken few steps, if any, to do so.

In 2024, the U.S. Environmental Protection Agency (EPA) adopted a rule that would initiate a series of actions to reduce exposure to harmful levels of fine particulate matter. This paper assesses where EPA stands in the process of implementing that rule and shines a light on why it is so important to faithfully implement it, as Congress mandated EPA to do under the Clean Air Act.

With environmental enforcement at a historic low, it’s open season for polluters.

Laura Thoms, Director of Enforcement: “This places the ability to delay enforcement directly in the hands of polluters. Delaying enforcement means that more pollution is spewed into the air, more waste is dumped into rivers, and more communities are put at risk.”

Jonathan Kalmuss-Katz, Attorney, Toxic Exposure & Health Program: “The science on formaldehyde hasn’t changed; these are the same arguments that the chemical industry’s been peddling for the last decade. The only difference is that they’ve finally found an administration willing to ignore the findings of its own scientists.”
