Trump EPA Rolls Back Environmental Protections: A Return to Haze and Pollution?
A shift in policy by the Environmental Protection Agency (EPA) under the Trump administration is raising concerns about air quality in and around national parks and wilderness areas. Recent actions indicate a weakening of the “regional haze rule,” a federal regulation designed to improve visibility by limiting emissions. The core of the issue centers on how states are required to demonstrate progress in reducing pollution.
The Regional Haze Rule: A Quarter Century of Progress
Established in 1999, the regional haze rule mandates that states develop plans every ten years to address air pollution impacting over 150 national parks, wilderness areas, and tribal lands across 36 states. Since its implementation, the rule has demonstrably improved air quality, with over 90% of affected areas experiencing reductions in sulfur and smog emissions. Visibility in some Western parks has increased from 90 to 120 miles, according to the Harvard Law School’s Environmental and Energy Law Program.
West Virginia: A Case Study in Policy Reversal
The situation in West Virginia exemplifies the changing approach. Initially, federal regulators rejected the state’s plan in early 2025, citing a failure to require twelve coal plants to assess the need for improved pollution controls. But, six months later, the EPA reversed course, approving the plan based on the state demonstrating visibility improvements that met projected benchmarks. This shift has sparked legal challenges from conservation groups like the National Parks Conservation Association, the Sierra Club, and Earthjustice.
EPA’s New Stance: Prioritizing Energy Supply
The EPA, under President Trump, has signaled a broader shift in priorities, emphasizing energy supply and reducing regulatory burdens on the fossil fuel industry. EPA Administrator Lee Zeldin announced plans to roll back 31 environmental regulations, including the regional haze rule, to “relieve regulatory pressure.” The agency has likewise indicated it won’t support state plans that involve closing coal-fired power plants without the consent of the plant owners, citing concerns about grid reliability.
Beyond West Virginia: Colorado and Hawaii
The impact extends beyond West Virginia. The EPA rejected Colorado’s plan in January 2026 because it would have led to the closure of a coal-burning power plant. Similarly, the agency is considering rejecting Hawaii’s plan, which calls for closing boilers at two power plants, arguing that the state hasn’t adequately demonstrated the legality of such closures. These actions suggest a pattern of favoring continued operation of fossil fuel facilities.
Legal Challenges and Conservationist Concerns
Conservationists argue that the EPA’s new policy allows polluting facilities to avoid necessary upgrades and undermines the goals of the regional haze rule. They contend that relying solely on visibility benchmarks allows plants to continue polluting without implementing pollution reduction technologies. Ulla Reeves, director of the National Parks Conservation Association’s clean air program, stated the agency is “blessing states that haven’t done a fine enough job.”
The Future of Air Quality in National Parks
The long-term consequences of these policy changes remain to be seen. Critics fear a return to the hazy conditions that plagued national parks before the implementation of the regional haze rule. Jim Schaberl, a former air and water quality manager at Shenandoah National Park, described the administration’s support for coal as “like digging up a grave.”
FAQ
Q: What is the regional haze rule?
A: It’s a federal regulation requiring states to improve visibility in national parks and wilderness areas by reducing air pollution.
Q: Why did the EPA reverse its decision on West Virginia’s plan?
A: The EPA changed course after the Trump administration took office, approving the plan based on visibility improvements meeting projected benchmarks, rather than requiring further pollution controls.
Q: What are conservation groups doing about these changes?
A: They are filing lawsuits challenging the EPA’s new policies and advocating for stronger environmental protections.
Q: What does the EPA say about these changes?
A: The EPA states it is committed to following the law and can’t approve state plans that don’t comply with legal requirements.
Did you know? The regional haze rule has led to a significant decrease in sulfur and smog emissions, improving visibility in many national parks.
Pro Tip: Stay informed about environmental regulations and advocate for policies that protect air quality in your community.
