EPA Proposes to Roll Back Interstate Air Pollution Regulations for Eight States

The Trump administration took a significant step Wednesday toward dismantling Obama-Biden era air pollution rules that regulate emissions crossing state lines, continuing its broader regulatory rollback agenda.

Environmental Protection Agency Administrator Lee Zeldin announced a proposal to approve plans from eight states to regulate their own ozone air pollution, effectively removing them from federal “good neighbor” requirements. The Supreme Court ruled earlier this year that the EPA could not enforce this interstate pollution regulation, which was designed to prevent coal-fired power plants and industrial facilities from significantly contributing to air pollution in neighboring states.

“Today, we are taking an important step to undo a Biden administration rule that treated our state partners unfairly,” Zeldin said in a statement. “These states will be able to advance cleaner air now for their communities, instead of waiting for overly burdensome federal requirements years from now.”

The affected states include Alabama, Arizona, Kentucky, Minnesota, Mississippi, Nevada, New Mexico and Tennessee. Under the Biden administration, the EPA had either disapproved or proposed disapproval of these states’ ozone control plans, arguing they didn’t adequately address pollution that crosses state lines.

The EPA’s announcement reflects the Trump administration’s commitment to what Zeldin describes as “cooperative federalism,” giving states more autonomy in determining how to meet air quality standards. The agency criticized the previous administration’s approach as a “heavy-handed, one-size-fits-all, federal mandate” for addressing smog-forming ozone.

According to the EPA’s statement, the agency has determined that these eight states have provided “adequate data demonstrating these states are not interfering with ozone attainment” required by National Ambient Air Quality Standards. The proposal also signals the EPA’s intention to withdraw proposed error corrections for state plans submitted by Iowa and Kansas.

The agency indicated it will address “interstate transport” obligations for remaining states covered by the Biden-era “Good Neighbor Plan” in a separate future action.

Environmental advocates have strongly criticized the move, arguing it will worsen air quality in downwind states that have little control over pollution crossing their borders. Air pollution from heavily industrialized Midwestern states like Indiana and Ohio frequently impacts air quality in East Coast states such as Connecticut and Delaware.

“Once again, Donald Trump and Lee Zeldin are choosing to protect aging, dirty and expensive coal plants and other industrial polluters over strong federal clean air protections that address interstate pollution problems,” said Zachary Fabish, a lawyer with the Sierra Club.

Fabish warned that “letting states off the hook while their pollution continues harming air quality in neighboring states is dangerous” and will make “Americans sicker and pay more for energy while doing so.”

The “good neighbor” rule is one of dozens of environmental regulations targeted by the Trump administration for reconsideration or repeal. The rollback effort has been praised by industry groups who view such regulations as economically burdensome, while environmental organizations argue the regulations are essential for protecting public health.

Cross-state air pollution has been a contentious issue for decades. Downwind states have long argued they unfairly bear the health and economic burdens of pollution generated elsewhere, while having limited regulatory authority to address its sources.

The EPA will accept public comments on the proposed rule for at least 30 days after it is published in the Federal Register. The outcome of the upcoming presidential election could significantly impact whether this regulatory change ultimately takes effect, as a change in administration often brings reversals in environmental policy priorities.

    As someone who follows the mining and commodities sectors, I’m interested to see how this EPA proposal might impact companies operating in the affected states. While it could provide more flexibility, I worry about the potential for a regulatory ‘race to the bottom’ that undermines environmental protections. What do you think the industry reaction might be?

    • Ava F. Rodriguez on

      That’s a valid concern. Industry groups may welcome the increased state autonomy, but responsible companies should also be mindful of the longer-term reputational and operational risks of lax environmental regulations. A balanced approach that prioritizes both economic growth and public health will be ideal.

  2. This is a significant development in the ongoing tug-of-war between federal and state authority on environmental issues. While I understand the desire for state flexibility, I’m concerned about the potential for this to lead to a patchwork of inconsistent regulations that could undermine air quality protections. What do you think the legal and political implications might be?

    • That’s a good point. This proposal is likely to face legal challenges and ongoing political battles, as different stakeholders argue over the right balance of federal oversight and state autonomy. The EPA will need to build a strong case to justify this change and address concerns about environmental protection.

  3. Elizabeth Martinez on

    This is an interesting development in the ongoing debate over interstate air pollution regulations. While the EPA’s proposal may provide more flexibility for states, it’s important to carefully weigh the potential impacts on air quality and public health. What do you think the long-term implications could be for the affected states and their neighbors?

    • Elizabeth Hernandez on

      You raise a good point. The balance between state autonomy and federal oversight on environmental issues is always a complex issue. It will be important to closely monitor air quality and public health outcomes in the affected states to ensure this change doesn’t lead to unintended consequences.

  4. The Supreme Court’s recent ruling that the EPA cannot enforce the ‘good neighbor’ pollution rule is certainly significant. This proposal to allow certain states to regulate their own ozone pollution seems like a pragmatic response, but I’m curious to see how it plays out in practice. What potential challenges or concerns do you foresee with this approach?

    • That’s a fair question. One concern I have is whether this could lead to a ‘race to the bottom’ as states compete to attract industry by relaxing environmental standards. Robust monitoring and enforcement will be crucial to ensure air quality doesn’t suffer.

  5. Isabella X. Moore on

    This is a complex issue without easy answers. On one hand, the states may feel the federal ‘good neighbor’ rule is overly burdensome. But on the other, we’ve seen how pollution can transcend state boundaries and have far-reaching consequences. I’m curious to hear more about the scientific and economic analysis that went into this EPA proposal.

    • Agreed, this is a nuanced issue that requires careful consideration of multiple factors. The EPA will need to provide a robust, data-driven justification for this change, addressing both the environmental and economic implications. Transparent public consultation will also be important.

  6. Liam Hernandez on

    While I understand the desire for state autonomy, I’m concerned that this move could undermine important safeguards against cross-border pollution. Air quality doesn’t respect state lines, so a patchwork of varying regulations seems problematic to me. What assurances can the EPA provide that public health will be adequately protected?

    • Oliver Martinez on

      That’s a valid concern. The EPA will need to ensure robust monitoring and enforcement mechanisms are in place to mitigate the risk of one state’s pollution adversely impacting its neighbors. Transparency and coordination between states will be crucial.

  7. Elizabeth Thompson on

    As an investor in energy and mining companies, I’m watching this development closely. While the flexibility for states could benefit certain businesses in the short term, the long-term implications for the environment and public health are more uncertain. Do you think this could impact the investment outlook for sectors like coal, oil, and metals?

    • Elizabeth J. Lee on

      That’s a good point. Any changes to environmental regulations have the potential to impact the investment landscape, particularly for industries like fossil fuels and mining. Investors will likely be closely analyzing the potential risks and opportunities as this policy evolves.
