EPA loosens pollution rules under Trump and Texas air quality may suffer

EPA finalizes new power plant emission rule

The EPA finalized updated emission standards for stationary combustion turbines, covering some new, modified, or reconstructed turbine units used in power generation and industrial settings.

EPA says the final approach relies mainly on combustion controls and includes compliance flexibilities, while critics argue it is less protective than the earlier proposal.

EPA estimated the final standards would cut NOx by up to 296 tons per year by 2032, far less than the about 2,659 tons projected under the proposed version.

Texas air quality faces risks from federal rollbacks

Texas communities may face higher health risks due to a significant rollback of federal environmental protections. Experts warned that these changes will strain public health in industrial and urban zones like Houston and Dallas.

Texas currently lacks a state-level rule to capture escaping methane emissions from its extensive energy infrastructure.

According to a data analysis cited in Texas Tribune reporting, methane intensity on New Mexico’s side of the Permian Basin is about half of Texas’s, an outcome supporters link to New Mexico’s tighter state methane rules.

EPA stops calculating value of human lives

The EPA said it will change how it weighs health benefits in its cost-benefit analyses, moving away from monetizing some public-health impacts when setting certain air rules.

The shift has drawn criticism from public-health and environmental advocates who argue it downplays real-world harms. The agency will now prioritize the direct costs to businesses when evaluating all future environmental regulations.

This decision officially abandons a practice used for 40 years to balance industry costs against avoided hospital visits. According to Texas Public Radio, previous estimates found stricter air standards provided $46 billion in benefits.

EPA proposes loosening the annual soot limit

After the 2024 EPA rule lowered the annual PM2.5 (soot) standard from 12 to 9 µg/m³, the Trump administration’s EPA has moved to undo that tightening and revisit the standard, including asking courts to vacate the 2024 rule as it develops a replacement approach.

EPA estimated the 2024 soot standard could avoid as many as 4,500 premature deaths in 2032, along with other health benefits.

Methane pollution protections face major delay

Federal officials extended the deadline for states to implement methane emission rules until next year. This extension represents an 18-month delay in requirements for oil companies to monitor leaks and end routine flaring.

The delay allows energy operators to continue using older equipment that releases potent gases into the air. This policy impacts millions of Americans living near oil fields who will face higher pollution levels.

According to the Environmental Defense Fund, methane is a climate pollutant 80 times more potent than carbon dioxide.

Methane rule delay increases total atmospheric pollution

EPA extended multiple compliance deadlines tied to the 2024 oil-and-gas methane standards.

In its own fact sheet on the interim delay, EPA projected that 3.8 million tons of methane emissions reductions would not occur over 2028–2038 due to the delayed timelines.

Environmental groups estimate that producers wasted about $3.5 billion worth of natural gas in 2023 through leaks, venting, and flaring, an amount they argue could cover the annual heating and cooking needs of every home in Michigan, Pennsylvania, and Texas.

Texas counties risk failing air quality tests

Because of these pollution changes, several large counties in Texas are at risk of poor air quality. Dallas, Harris, Tarrant, and Bowie counties were almost labeled as failing air quality tests under the old 9-microgram soot rule.

If a county fails these tests, the state must legally create a plan to clean up the air. However, the federal government is now moving to make the tests easier to pass.

According to the Texas Tribune, this could mean these areas will not have to reduce diesel pollution from trucks. This keeps the air dirtier.

Dallas region faces mandatory ozone deadline

The Dallas-Fort Worth area is already working on a special plan to address a different type of pollution, ozone. On July 22, 2024, the region was reclassified to a serious level of ozone pollution.

This area includes nine counties, such as Collin, Denton, and Johnson, that must meet clean air goals by August 3, 2027. To meet this deadline, the air must show improvement in 2026.

According to the Texas Commission on Environmental Quality, factories that release 50 tons of chemicals a year must follow strict rules. This local goal remains crucial.

San Antonio implements new smog inspections

While some federal rules are being eased, the city of San Antonio is launching a new program to improve its air quality. Beginning on November 1, 2026, people living in Bexar County must have their cars pass an emissions inspection.

This test is required for gasoline cars that are between 2 and 24 years old. Drivers cannot renew their car registration if their vehicle fails this test.

According to the Texas Commission on Environmental Quality, this is part of the state’s plan to reduce ozone in the area. This local effort helps keep the city’s air safer.

EPA delays mercury and air toxics standards

On April 8, 2025, the president signed a proclamation granting certain coal plants listed by the EPA a two-year compliance exemption tied to the strengthened MATS rule. EPA says the exemption runs from July 8, 2027, through July 8, 2029.

Mercury is a dangerous neurotoxin that can end up in water and soil and concentrate in fish. It is perilous for young children and pregnant women.

EPA also issued a June 2025 proposal to repeal key parts of the Biden-era 2024 MATS updates, and EPA published a fact sheet describing the proposal and projected cost savings.

Federal budget proposal shrinks the EPA

The president has proposed a budget that would significantly reduce the Environmental Protection Agency’s budget. The 2026 budget proposal for the agency is $4.16 billion, 54% less than in 2025.

This plan would reduce the number of workers to 12,856 positions, the lowest level in 40 years. This means there will be 1,274 fewer full-time employees to check if companies are following the laws.

According to official budget documents, the goal is to end programs that fall outside the agency’s core mission. This makes it harder for the agency to enforce rules.

Groups oppose weakening of vehicle rules

Many health groups are worried that easing car pollution rules will make more children sick. On January 14, 2026, 75 groups wrote a letter to the Environmental Protection Agency to oppose these changes.

They say that the 2024 vehicle rules were expected to prevent 25 million asthma attacks. These rules would have also prevented 50,000 early deaths. The administration is now reconsidering these standards to make cars more affordable.

According to the Environmental Defense Fund, the current vehicle pollution levels are linked to heart attacks and strokes. This debate remains a significant health issue.

EPA moves to rescind the Endangerment Finding

The most significant change to environmental law is a proposal to end the regulation of greenhouse gas emissions from cars. On July 29, 2025, the Environmental Protection Agency proposed to rescind the 2009 Endangerment Finding.

This finding is the legal basis for the government’s rules on gases that cause climate change. If this is removed, the agency will no longer have the legal power to set carbon standards for cars and trucks.

According to the Environmental Protection Agency, this move will help lower the cost of owning a car. This is a final step in removing many federal climate rules.
