EPA Launches Biggest Deregulatory Action in U.S. History: Zeldin Rolls Out 31 Groundbreaking Actions to Save Americans TRILLIONS, Slash Costs and Supercharge Job Growth

U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin has rolled out 31 groundbreaking actions to dismantle the suffocating web of radical environmental rules strangling America’s economy.
These bold reforms advance President Trump’s Day One executive orders, promising to unleash American energy dominance, drastically lower living costs for American families, supercharge economic growth, and restore constitutional governance by empowering state authorities.
“Today, I’m pleased to make the largest deregulatory announcement in U.S. history,” declared Administrator Zeldin in a fiery video statement.
“The Environmental Protection Agency is initiating 31 historic actions to fulfill President Trump’s promise to unleash American energy, revitalize our auto industry, restore the rule of law, and give power back to the states.”
Zeldin specifically called out numerous Biden-era regulations that he characterized as “suffocating,” burdensome, and devastatingly costly to everyday Americans.
Among the regulations being reconsidered are the following:
UNLEASHING AMERICAN ENERGY
- Reconsideration of regulations on power plants (Clean Power Plan 2.0)
- Reconsideration of regulations throttling the oil and gas industry (OOOO b/c)
- Reconsideration of Mercury and Air Toxics Standards that improperly targeted coal-fired power plants (MATS)
- Reconsideration of mandatory Greenhouse Gas Reporting Program that imposed significant costs on the American energy supply (GHG Reporting Program)
- Reconsideration of limitations, guidelines and standards (ELG) for the Steam Electric Power Generating Industry to ensure low-cost electricity while protecting water resources (Steam Electric ELG)
- Reconsideration of wastewater regulations for coal power plants to help unleash American energy (Oil and Gas ELG)
- Reconsideration of Biden-Harris Administration Risk Management Program rule that made America’s oil and natural gas refineries and chemical facilities less safe (Risk Management Program Rule)
LOWERING THE COST OF LIVING FOR AMERICAN FAMILIES
- Reconsideration of light-duty, medium-duty, and heavy-duty vehicle regulations that provided the foundation for the Biden-Harris electric vehicle mandate (Car GHG Rules)
- Reconsideration of the 2009 Endangerment Finding and regulations and actions that rely on that Finding (Endangerment Finding)
- Reconsideration of technology transition rule that forces companies to use certain technologies that increased costs on food at grocery stores and semiconductor manufacturing (Technology Transition Rule)
- Reconsideration of Particulate Matter National Ambient Air Quality Standards that shut down opportunities for American manufacturing and small businesses (PM 2.5 NAAQS)
- Reconsideration of multiple National Emission Standards for Hazardous Air Pollutants for American energy and manufacturing sectors (NESHAPs)
- Restructuring the Regional Haze Program that threatened the supply of affordable energy for American families (Regional Haze)
- Overhauling Biden-Harris Administration’s “Social Cost of Carbon”
- Redirecting enforcement resources to EPA’s core mission to relieve the economy of unnecessary bureaucratic burdens that drive up costs for American consumers (Enforcement Discretion)
- Terminating Biden’s Environmental Justice and DEI arms of the agency (EJ/DEI)
ADVANCING COOPERATIVE FEDERALISM
- Ending so-called “Good Neighbor Plan” which the Biden-Harris Administration used to expand federal rules to more states and sectors beyond the program’s traditional focus and led to the rejection of nearly all State Implementation Plans
- Working with states and tribes to resolve massive backlog with State Implementation Plans and Tribal Implementation Plans that the Biden-Harris Administration refused to resolve (SIPs/TIPs)
- Reconsideration of exceptional events rulemaking to work with states to prioritize the allowance of prescribed fires within State and Tribal Implementation Plans (Exceptional Events)
- Reconstituting Science Advisory Board and Clean Air Scientific Advisory Committee (SAB/CASAC)
- Prioritizing coal ash program to expedite state permit reviews and update coal ash regulations (CCR Rule)
- Utilizing enforcement discretion to further North Carolina’s recovery from Hurricane Helene
“For me, the U.S. Constitution and the laws of this nation will be strictly interpreted and followed—no exceptions. Today, the Green News scam ends, as the EPA does its part to usher in the golden age of American success,” Zeldin said.
“Our actions will lower the cost of living by making it more affordable to purchase a car, heat your home, and operate a business. Jobs will be created, especially in the U.S. auto industry, and our nation will become stronger for it. From the campaign trail, to day one, and beyond, President Trump has delivered on his promise to unleash energy dominance and lower the cost of living. We at the EPA will do our part to power the great American comeback,” he added.
