Getting the strongest possible Environmental Protection Agency regulations for clean air across the finish line is core to our work at Moms Clean Air Force. We gather petition signatures, recruit volunteers to testify at public hearings, and hold meetings with EPA officials to ensure our children are protected from harmful pollutants, like soot, smog, and mercury.
Currently, EPA Administrator Lee Zeldin is creating chaos and confusion with massive attempts to roll back protections from pollution. He and President Trump are also inventing ways to go around the legal and regulatory processes to shortcut and evade requirements for pollution controls.
Read a timeline of efforts to gut protections during the first 100 days of Trump’s administration. As new deregulatory actions open up for public comment, we will post them below.
These are the proposed regulations EPA is currently considering:
Mercury and Air Toxics Standards (MATS) Rollback
In June 2025, EPA announced a proposed rollback of the 2024 Mercury and Air Toxics Standards. The proposed rollback would remove the new requirement for continuous emissions monitoring for coal plants and reopen the “lignite loophole,” which allows power plants that burned lignite coal to emit more toxic pollution than other plants. Moms are sounding the alarm.
Join us in taking action to preserve the strong 2024 MATS.
Power Plant Rule Rollback
In June 2025, EPA proposed a repeal of the 2024 rule to limit carbon pollution from power plants, the second largest source of climate pollution in the country. We cannot look away from our responsibility to clean up this pollution so that our families have cleaner air and a more stable climate.
Join Moms Clean Air Force in taking action to preserve the power plants rule.
Designation of Vinyl Chloride as High Priority Substance
In December 2023, EPA began the long-awaited process to review five chemicals for regulatory action under the Toxic Substances Control Act (TSCA). Among these five chemicals is vinyl chloride, a known human carcinogen that is used to make PVC plastic. This is an essential step toward banning vinyl chloride from household and commercial products—and Moms spoke out in testimony and in written comments to EPA before the comment period closed in March 2024.
NOx Emissions Standards for New Stationary Combustion Turbines
In November 2024, EPA proposed an update to nitrogen oxide (NOx) pollution protections for new gas-fired power plants. NOx is a dangerous pollutant that has been linked to many health harms. It also contributes to dangerous particle and ozone pollution. Moms testified before EPA at a public hearing on this rule in January 2025 and submitted more than 10,000 written comments for the docket before it closed in March.
