Week of September 7

As the calendar turns toward fall, last week’s environmental and energy headlines reflected both familiar trends and a few surprises. Data centers, grid infrastructure, nuclear energy, permitting disputes, and environmental regulation all remained in the spotlight. At the same time, I came across a particularly intriguing research project involving discarded oyster shells and rare earth metals. While still in its early stages, the concept is a fascinating example of how innovative thinking may one day help address both waste management and water quality challenges.

Transportation Corridors Could Become the Next Energy Superhighways

Federal policymakers are increasingly exploring whether existing highway and railroad rights-of-way can be used to accelerate deployment of transmission lines, broadband infrastructure, water pipelines, and other utility projects. Several initiatives are focused on leveraging existing transportation corridors to reduce siting conflicts, streamlining permitting, and helping meet growing electricity and communications demand driven by artificial intelligence, manufacturing, and economic development.

Massachusetts Establishes New Data Center Development Framework

Massachusetts adopted a comprehensive statewide framework governing large-scale data center development. The new requirements focus on grid impacts, community benefits, environmental performance, water use, and local engagement, reflecting growing state-level attention to the infrastructure demands and community impacts associated with large data center projects. Read more: Governor Healy Press Release.

Oyster Shells Show Promise for Cleaning Contaminated Water

Researchers in Ireland found that crushed oyster, mussel, and cockle shells may be capable of removing rare earth metals from contaminated water while simultaneously recovering those materials in solid form. The process is still in the research phase and requires further testing, but the concept is particularly interesting because it could potentially transform an abundant waste product into a low-cost tool for addressing water contamination and resource recovery.

States Challenge Endangered Species Act Rollbacks

A coalition of states filed lawsuits seeking to overturn several recent Endangered Species Act regulatory changes. Among other issues, the lawsuits challenge revisions to the definition of “harm” and other protections, setting up what is likely to become another significant legal battle over the future scope of federal endangered species regulation. See, e.g., Mass. v. U.S. Fish & Wildlife Service, No. 4:26-cv-10072 (N.D. Cal. filed Sept. 9, 2026) and California v. Burgum, No. 3:26-cv-10071 (N.D. Cal. filed Sept. 9, 2026).

Read more: Supply Chain Brain.

Energy Credit Dispute Sparks Interstate Lawsuit

West Virginia filed suit challenging Pennsylvania’s restrictions on certain energy credit markets, arguing that the state’s program improperly favors in-state energy producers. The lawsuit raises Commerce Clause questions and highlights the continued tension between state clean energy programs and regional electricity markets. See West Virginia ex rel. McCuskey v. Pennsylvania Public Utility Comm., No. 3:26-cv-02527-KM (M.D. Pa. filed Sept. 3, 2026). Read more: The Center Square.

Appeals Court Vacates Pipeline Water Permit

The Third Circuit vacated a key water quality certification for the proposed Northeast Supply Enhancement natural gas pipeline project, concluding that New Jersey regulators did not adequately explain their decision to approve the permit. The ruling sends the matter back for further review and creates another hurdle for a project intended to expand natural gas supplies in the Northeast. See NRDC v. NJDEP, Nos. 26-1252 & 26-1253 (3d Cir. Sept. 8, 2026). Read more: Reuters.

Federal Government Supports Nuclear Plant Restart

The Department of Energy announced up to $1.9 billion in financing to support the restart of a shuttered nuclear power plant in Iowa.

Week of August 31, 2026

Labor Day may mark the unofficial end of summer, but environmental and energy regulators, courts, and policymakers show no signs of slowing down. Last week’s developments focused on several familiar themes, including federal permitting reform, the ongoing evolution of Clean Water Act jurisdiction, state climate initiatives, the impact of Congressional action, and the continued expansion of producer responsibility laws.

EPA Revisits WOTUS Definition with Focus on Drought Conditions

EPA and the U.S. Army Corps of Engineers issued a supplemental proposal to revise the definition of “waters of the United States” (WOTUS). The proposal would place greater emphasis on drought conditions when determining whether streams and wetlands qualify for Clean Water Act protection, continuing the Trump administration’s effort to align federal jurisdiction with the Supreme Court’s decision in Sackett v. EPA, 598 U.S. 651 (2023), balancing private property rights and maintaining water quality. Read more: EPA and ACOE Press Release.

Oregon’s Packaging Producer Responsibility Law Survives Constitutional Challenge

Read more: Court’s Findings of Fact and Conclusions of Law.

New York Climate Superfund Law Suffers Major Setback

A federal judge ruled that New York’s Climate Change Superfund Act cannot be enforced, concluding that the law is preempted by federal law and conflicts with national interests in regulating greenhouse gas emissions. West Virginia v. James, No. 1:25-cv-00168-BKS-DJS (N.D.N.Y. Aug. 31, 2026). The decision represents one of the most significant judicial challenges to state climate superfund laws and could have implications for similar efforts in other states. Read more: The Hill.

House Advances Bill to Accelerate Mining Permits

The U.S. House of Representatives passed legislation – Protecting Domestic Mining Act (H.R. 1501) – that would make all mining and mineral processing projects eligible for the FAST-41 federal permitting program.

Ninth Circuit Upholds EPA’s New-Chemicals Review Rule

The Ninth Circuit upheld EPA’s 2024 rule establishing procedures for reviewing new chemicals under the Toxic Substances Control Act. The court concluded that EPA acted within its authority by permitting some persistent, bioaccumulative, and toxic chemicals to undergo a 30-day review rather than the standard 90-day process and reasonably declined to impose a categorical ban. Read more: Case Miner Copy of Decision

Data Center Electricity Demand Raises Water-Supply Concerns

A Ceres report estimates that power generation serving data centers in seven states withdraws approximately 3.4 trillion gallons of freshwater annually, underscoring the relationship between expanding computing infrastructure and local water availability. The report focuses on withdrawals rather than consumption, however, and some experts caution that including water returned to rivers, particularly water passing through hydropower facilities, could overstate the practical impact. Read more: Ceres Report

Aluminum-Based System Targets Cleaner Data Center Backup Power

Voya Energy raised $35 million to develop a system that uses scrap aluminum as a potential alternative to diesel backup generators at data centers.
