In a move that has sparked significant debate, the U.S. Environmental Protection Agency (EPA) has dismissed Colorado’s recent air-quality initiative, citing non-compliance with federal regulations. This decision, affecting the visibility in national parks and wilderness areas, has raised questions about state authority and federal oversight in environmental policy.
The EPA’s refusal to accept Colorado’s 2022 Regional Haze State Implementation Plan (SIP) was attributed to the plan’s mandate for coal-fired plant closures without operator consent, which the agency stated contravened the Clean Air Act’s provisions. The EPA emphasized that the plan would have led to “the premature closure of power plants,” a situation it deemed unacceptable.
According to Colorado Governor Jared Polis, “The Trump administration chose dirtier air and higher costs … and rejected Colorado’s and utilities’ careful plans to save people money and increase energy availability and reliability.” The governor’s office argued that maintaining outdated coal plants would elevate costs, degrade air quality, and hinder the transition to cleaner energy sources.
The Regional Haze Program, established in 1999, obligates states to curtail pollutants that obscure views in protected natural areas. EPA Administrator Lee Zeldin expressed the agency’s willingness to collaborate with Colorado to produce a compliant plan, ensuring alignment with the Clean Air Act.
Colorado’s proposed closure of the Nixon Unit 1 by 2028 was a particular point of contention, as the EPA highlighted the absence of necessary legal assurances under Section 110 of the Clean Air Act. Additionally, the agency voiced concerns about potential threats to “grid reliability,” referencing an emergency order from the Department of Energy (DOE) that required Craig Station’s Unit 1 to continue operations due to an energy crisis in the West.
The EPA stated unequivocally, “The Trump EPA is unequivocally committed to following the Clean Air Act, and EPA legally cannot approve Colorado’s SIP revision.” The agency underscored that plant shutdowns were unnecessary to fulfill regional haze requirements, suggesting that forcing closures could misuse the Clean Air Act.
Colorado now has a two-year window to devise an acceptable plan or face a federally imposed implementation plan, as indicated by the EPA. The decision ignited a political and policy backlash within the state, with leaders criticizing it as a setback for environmental and economic goals.
Political Repercussions
State officials, including Senator Michael Bennet, denounced the EPA’s decision as detrimental to consumers and climate goals. “It’s unacceptable to burden ratepayers with unnecessary costs,” Bennet remarked, condemning the federal intervention as a hindrance to long-term planning. He accused the administration of leveraging federal energy policy to retaliate against states with progressive clean energy targets.
Michael Ogletree from the Colorado Department of Public Health and Environment argued that the EPA’s ruling undermines the progress achieved through the Regional Haze Program. He maintained that Colorado’s plan was “highly protective” and aligned with both state and federal requirements.
Tri-State Generation and Transmission Association, a co-owner of Craig Station, is currently assessing the implications of the EPA’s disapproval. Tri-State emphasized its commitment to grid reliability and rising energy demand, regardless of regulatory changes.
Future Steps for Colorado
Colorado must now resubmit a revised SIP that satisfies the EPA’s criteria or face a federally mandated plan within two years. Meanwhile, the EPA has delayed the next phase of the regional haze program planning process, extending the deadline to 2031 to allow states more time to align their plans with upcoming regulations.
The EPA initially signaled partial approval of Colorado’s plan in 2025, but energy supply concerns and the DOE’s directive to maintain Craig Station operations led to a full rejection. EPA Regional Administrator Cyrus Western affirmed that the decision complies with the Clean Air Act while committing to clean air standards.
This development highlights the ongoing tension between state environmental ambitions and federal priorities, raising questions about the balance of power in climate policy.
