The Colstrip Power Plant in Montana is now one of the early applicants to the new EPA exemption application process which we have previously discussed here. Specifically, the Colstrip plant has requested a two-year exemption from EPA standards regarding air pollution.

Previously, in April 2024, this power plant was subject to stricter standards under updates to the Mercury and Air Toxics Standards (MATS) for power plants which was targeted at reducing airborne emissions of heavy metals including lead, arsenic, and mercury and had a compliance …

The Environmental Protection Agency announced March 12 it set up an e-mail account allowing the regulated community to request a presidential exemption under Section 112(i)(4) of the Clean Air Act (“CAA”). 

The CAA permits the president to grant exemptions to stationary sources from compliance with any standard or limitation set forth under Section 112 for up to two years if the technology required to meet the standard is not available and if it’s in the United States’ national security interests.

In particular, the EPA requested …

SCOTUS Declines to Review EPA’s Authority on California’s Vehicle Emission Standards

In a significant development for environmental law and state autonomy, the Supreme Court of the United States (SCOTUS) recently declined to review whether the U.S. Environmental Protection Agency (EPA) has the authority to grant California a waiver to set its own greenhouse gas (GHG) emissions standards for vehicles. This decision leaves in place California’s ability to implement stricter emission rules, marking a key moment in the ongoing battle over federal and state environmental regulations.…

The Environmental Protection Agency announced on Nov. 12 its final rule to further reduce methane emissions from oil and gas industries as required under the Inflation Reduction Act. 

In particular, Congress established a Waste Emissions Charge for high-emitting oil and gas facilities once emissions exceed 25,000 metric tons of carbon dioxide equivalent per year to the Greenhouse Gas Reporting Program. Coupled with the final Clean Air Act standards issued in March, the Waste Emission Charge is a central component of EPA’s efforts to reduce methane …

On October 16, the U.S. Supreme Court rejected an attempt to block the implementation of the U.S. Environmental Protection Agency’s latest effort to curb greenhouse gas emissions (GHG) from power plants while the EPA is being challenged in pending court proceedings, but three justices indicated they had concerns with the rule’s legality.

The October 16 order arises out the emergency stay applications filed by multiple Republican-led states, utility and coal industry groups after the D.C. Circuit Court rejected their stay bids in July. These parties …

Last week, in a 5-4 opinion, in Ohio v. Environmental Protection Agency, the U.S. Supreme Court granted applications for a stay of the implementation of the “Good Neighbor” Plan, the EPA’s federal emissions reduction rule, set in 2015. The application of this rule was intended to address transboundary ozone pollution that can exacerbate health hazards. As previously explained by ELM, the Clean Air Act’s Good Neighbor provision enabled the EPA to require each state to implement regulations meant to reduce emissions that would …
