EPA Proposes Changes to Clean Water Act, Aiming to Streamline Oil and Gas Project Approvals
the Environmental Protection Agency (EPA) is moving forward with a proposed rule designed to clarify and potentially limit the authority states have under Section 401 of the Clean water act. This section allows states to review and potentially block projects that could impact water quality, and the EPA believes some states have been misusing this power to obstruct energy projects for reasons beyond environmental protection. The agency anticipates issuing a final rule this spring.
The Core of Section 401 and Recent State Actions
Section 401 of the Clean Water Act requires any applicant for a federal license or permit that may result in a discharge into navigable waters to obtain a water quality certification from the state in which the project is located.This certification ensures the project complies with state water quality standards. In recent years, several states, especially those with Democratic leadership, have actively utilized Section 401 to challenge projects like pipelines and export terminals, citing potential harm to local waterways.
These actions haven’t been without legal challenges. Such as, in 2017, Washington State, under Governor Jay Inslee, successfully used Section 401 to deny a permit for a proposed coal export terminal in Longview, Washington.the state argued the project would cause meaningful and unmitigable environmental damage. Courts ultimately upheld this decision,effectively halting the project.Inside Climate News details this case as a key example of Section 401’s use.
Similarly,in 2020,then-New York Governor Andrew Cuomo denied a permit for the Constitution Pipeline,a natural gas pipeline intended to transport fuel from pennsylvania to New York,citing concerns about water quality impacts. However, the situation shifted, and in 2025, Governor Kathy Hochul approved a permit for the same pipeline project, demonstrating the changing political landscape and potential for differing interpretations of Section 401.
EPA’s Concerns and Proposed Changes
According to the EPA, the proposed rule aims to address what the agency views as an overreach of state authority under section 401. EPA official, kramer, stated the changes are intended to prevent states from “weaponizing” the law to block projects based on political considerations rather than legitimate water quality concerns. The EPA believes a clearer, more consistent national standard is needed to ensure efficient project approvals while still protecting water resources.
The proposed changes are expected to focus on defining the scope of what states can consider when reviewing projects, potentially limiting their ability to raise concerns about broader environmental impacts beyond water quality. this could involve clarifying the types of conditions states can impose on permits and setting time limits for state reviews.
Public Response and Concerns
The EPA held two public webinars last summer to gather input on the proposed changes. An EPA summary of the discussions reveals that at least 14 speakers emphasized the Clean Water Act’s success in improving water quality and highlighted section 401’s crucial role in protecting rivers and aquatic ecosystems.
Many speakers expressed concerns that a revised rule could weaken state and Tribal authority, potentially undermining public health, environmental protection, and local economies. They argued that states should retain the ability to consider the cumulative impacts of projects on water resources and to deny permits if those impacts are unacceptable.
What’s Next?
The EPA is now preparing to open a 30-day public comment period, allowing stakeholders to submit their feedback on the proposed rule.Following the review of these comments,the agency intends to finalize the rule this spring. This final rule will likely be subject to further legal challenges, as states and environmental groups may contest any limitations on their authority under Section 401.
Key Takeaways
- The EPA is proposing changes to Section 401 of the Clean Water Act to streamline approvals for energy projects.
- States have increasingly used Section 401 to block projects they believe would harm water quality, leading to legal battles.
- The EPA argues some states are misusing Section 401 for political reasons, while opponents fear the changes will weaken environmental protections.
- A 30-day public comment period will follow, with a final rule expected this spring.
