The Environmental Protection Agency (EPA) has unveiled a sweeping set of deregulatory measures, aiming to ease restrictions on industries by rolling back key environmental protections. EPA Administrator Lee Zeldin announced nearly three dozen changes, arguing that these reforms will reduce burdens on businesses and stimulate economic growth. However, environmental groups have raised concerns, warning that these rollbacks could significantly weaken safeguards for clean air and water.
Key Regulatory Changes:
Review of Power Plant Emission Standards
The Biden administration had implemented strict limits on greenhouse gas emissions from gas- and coal-fired power plants as part of its climate policy. Zeldin stated that the EPA would reassess these regulations, citing concerns over potential constraints on energy production.
Reevaluation of Toxic Emission Limits on Power Plants
Coal-fired power plants emit hazardous metals like mercury, and the Biden administration had introduced stringent rules to limit these pollutants. The EPA announced plans to review these regulations following lawsuits from nearly two dozen states, which argue that compliance costs are too high. Additionally, a potential two-year compliance extension is under consideration for affected industries.

Reassessment of Wastewater Regulations for Power Plants
Coal and steam-powered plants discharge toxic substances, including mercury and arsenic, into wastewater, posing health risks. While the Biden administration had tightened wastewater disposal regulations, the EPA now plans to revisit these restrictions, citing concerns over increased industry costs and higher residential energy prices.
Expanded Uses for Oil and Gas Wastewater
Currently, treated wastewater from oil and gas drilling has limited applications, such as agricultural use in select western regions. The EPA plans to explore new potential uses, including cooling data centers and fire suppression. Critics argue that wastewater may contain harmful contaminants, while supporters claim that modern treatment technologies can mitigate such risks.
Modification of Petrochemical Emergency Planning
The Biden administration had strengthened safety requirements for industrial and chemical plants, requiring more stringent risk management measures. These rules were intended to prevent incidents like the 2019 Texas explosion, which led to mass evacuations. The EPA is now reassessing these safety requirements, citing concerns about national security vulnerabilities due to increased public disclosure mandates.
Review of Greenhouse Gas Reporting Requirements
The EPA’s mandatory emissions reporting program, which requires major industrial polluters to disclose their greenhouse gas emissions, is under review. Zeldin described the program as an expensive bureaucratic burden that does not directly improve air quality. However, proponents argue that emission data helps companies identify cost-saving opportunities while reducing pollution.
Reevaluation of Vehicle Emissions Standards
The EPA plans to review emissions regulations for light-, medium-, and heavy-duty vehicles. Zeldin characterized these regulations as a cornerstone of the Biden administration’s push for electric vehicles (EVs), despite the fact that automakers were not mandated to sell EVs. Rolling back these standards would permit higher greenhouse gas emissions, though many automakers have already begun investing in cleaner technologies.
Review of the 2009 Endangerment Finding
The 2009 Clean Air Act’s Endangerment Finding determined that greenhouse gases pose a threat to public health, forming the legal foundation for U.S. climate policies. The Trump administration had previously ordered a review of its legality, and the current EPA is now reconsidering its status. Experts warn that reversing the finding could have severe consequences for climate policy.
Reconsideration of Hydrofluorocarbon (HFC) Regulations
HFCs, potent greenhouse gases used in refrigeration and air conditioning, have been subject to strict controls to curb their impact on climate change. Many countries have pledged to phase out HFCs, but the EPA is now reviewing these regulations, potentially loosening restrictions.
Abolition of the ‘Good Neighbor Plan’
Scientists raise concerns as the US stops sharing air quality data
This policy aimed to limit cross-state air pollution from power plants to reduce smog exposure in downwind communities. The EPA now seeks to terminate the rule, though the Supreme Court had already suspended its implementation, siding with states that challenged it.
Restructuring of Scientific Advisory Committees
The EPA’s Science Advisory Board and Clean Air Scientific Advisory Committee, responsible for guiding environmental policy based on scientific research, are being restructured. These panels play a crucial role in shaping regulations, and past administrations have been criticized for politicizing their composition.
Reevaluation of Particulate Matter Standards
Particulate matter, or soot, from industrial facilities can enter the bloodstream, leading to respiratory illnesses. The Biden administration had tightened regulations, citing research that linked exposure to premature deaths and asthma. The EPA now argues that the existing standards are already effective and sees the regulations as an obstacle to economic activity.
Review of Air Pollution Standards for Energy and Manufacturing Sectors
The EPA’s national emission standards regulate pollutants known to cause cancer and other health issues. The agency is now considering exemptions, including a two-year compliance delay for facilities affected by these rules.
Overhaul of the Regional Haze Program
For decades, this program has reduced pollution that obscures scenic views in national parks. While air quality has improved, Zeldin argues that the program is being misused to justify shutting down industrial plants, and the EPA will review its implementation.
Revision of the ‘Social Cost of Carbon’ Calculation
The social cost of carbon helps quantify the economic impact of greenhouse gas emissions. The Biden administration set the figure at $190 per ton to account for climate-related damages. The EPA, following an executive order, is now considering eliminating the metric altogether, aligning with policies that prioritize fossil fuel production.
Changes to the Coal Ash Regulation Framework
Coal ash, a byproduct of coal combustion, contains hazardous pollutants such as arsenic and mercury. The Biden administration had tightened regulations to hold companies accountable for cleaning up coal ash sites. The EPA is now shifting regulatory oversight to individual states, raising concerns that environmental protections could weaken.
Implications and Reactions
Industry groups have welcomed these regulatory rollbacks, arguing that they will reduce costs and prevent excessive government intervention. However, environmental organizations have expressed alarm, warning that these changes could have long-term negative impacts on public health, climate action, and ecological protection.

As the EPA moves forward with these deregulatory actions, the decisions will likely face legal challenges from environmental groups and states opposed to weaker regulations. The coming months will determine how these policy shifts reshape environmental protections and industrial operations across the U.S.
