Trump Administration's EPA Policy Changes Raise Concerns Over National Park Air Quality

Overview of the Policy Shift
The Trump administration's Environmental Protection Agency (EPA) has implemented significant changes to air quality regulations, particularly affecting national parks and wilderness areas. These changes have raised alarms among conservationists who argue that the new policies could lead to a deterioration of air quality and visibility in these protected areas.
Key Changes in EPA Regulations
Historically, the regional haze rule mandated states to develop plans every decade to limit emissions and monitor air pollution in over 150 national parks and wilderness areas across 36 states. This regulation has contributed to a substantial reduction in sulfur and smog emissions, improving visibility from an average of 90 miles to 120 miles in some Western parks since its inception in 1999. However, under the Trump administration, the EPA has signaled a shift in its approach. In March 2025, EPA Administrator Lee Zeldin announced plans to roll back 31 environmental regulations, including the regional haze rule, citing the need to relieve regulatory pressure on the fossil fuel industry.
Implications for Specific States
The EPA's approval of West Virginia's pollution control plan, which previously faced rejection, exemplifies this policy shift. The agency now allows states to demonstrate compliance with visibility benchmarks without requiring comprehensive evaluations of pollution control technologies. This change has prompted lawsuits from environmental groups, including the National Parks Conservation Association and the Sierra Club, who argue that it undermines efforts to maintain air quality in national parks like Shenandoah and the Great Smoky Mountains.
In Colorado, the EPA rejected a state plan that proposed closing a coal-burning power plant, citing concerns over electricity supply and legal compliance. Similarly, Hawaii's plan to shut down several power plant boilers is under review, with the EPA indicating it may also reject this proposal. The agency's stance emphasizes the importance of maintaining reliable energy supplies, framing coal-fired power plants as essential for meeting energy demands and national security interests.
Criticism from Environmental Advocates
Critics of the EPA's new policies argue that they represent a significant rollback of environmental protections. Ulla Reeves, director of the National Parks Conservation Association’s clean air program, expressed concern that the agency is allowing states to avoid necessary pollution reductions. Joshua Smith, an attorney for the Sierra Club, described the new policy as a "backdoor way to kick the can down the road," potentially allowing polluting facilities to evade accountability.
Jim Schaberl, a former air and water quality manager at Shenandoah National Park, highlighted the improvements in visibility achieved over the years, warning that the current administration's support for coal could reverse these gains. He stated, “To try to resurrect coal is like digging up a grave, and this administration wants to dig up that grave.”
Official Statements
EPA spokesperson Brigit Hirsch defended the agency's actions, asserting that it is committed to following the law and cannot approve state plans that do not comply with legal standards. The agency maintains that its decisions are based on ensuring affordable and reliable energy supplies while adhering to regulatory requirements.
Conclusion
The Trump administration's changes to EPA regulations concerning air quality in national parks have sparked significant debate. While the administration emphasizes the need for energy reliability, conservationists warn that these policies could jeopardize the progress made in improving air quality and visibility in some of the nation's most cherished natural landscapes.
