United StatesUS Interior Establishes Geothermal Exploration Categorical Exclusion for BLM NEPA Reviews
The US Department of the Interior has finalised a new NEPA categorical exclusion allowing the Bureau of Land Management to approve qualifying geothermal exploration notices of intent without preparing environmental assessments or impact statements, effective 28 April 2026. This streamlines early-stage geothermal projects on BLM-managed lands while still requiring extraordinary-circumstances review, potentially shortening permitting timelines for renewable energy exploration.
United StatesUS BOEM Issues Final EIS for DCOR Well Stimulation Treatments on Platform Gilda Offshore California
In April 2026 the US Bureau of Ocean Energy Management issued a final environmental impact statement for DCOR’s proposed hydraulic fracturing well stimulation programme on Platform Gilda offshore California, following an expedited NEPA process after earlier court challenges. The EIS signals that any approval will hinge on closed-loop handling and reinjection of stimulation fluids, no open-ocean discharge, stringent well integrity and spill controls, and constrained air and greenhouse gas emissions, setting a reference point for how future offshore well stimulation proposals may be evaluated.
United StatesUS Congress Introduces CERTAIN Act To Expedite Federal Project Authorizations
A bipartisan US House bill (HR 8308, the CERTAIN Act) introduced in April 2026 would standardise and accelerate federal project authorisations and environmental reviews by imposing firm timelines, limiting revocations, and tightening judicial review. If enacted, this cross-cutting permitting reform would materially reshape NEPA-based approval processes across sectors, potentially shortening lead times for major infrastructure and industrial projects while increasing litigation leverage when agencies delay or reverse approvals.
United StatesUS NOAA NMFS Initiates PEIS Scoping for Aquaculture Opportunity Areas in Gulf of Alaska State Waters
NOAA’s National Marine Fisheries Service has opened a 45-day scoping period, including two virtual public meetings, to prepare a programmatic environmental impact statement for identifying aquaculture opportunity areas in Alaska state waters of the Gulf of Alaska. This planning-only step signals potential future siting of shellfish and seaweed farms in designated areas, with later NEPA and permitting decisions likely to shape operational, environmental, and community requirements for aquaculture developers.
United StatesUS FERC Opens NEPA Scoping and Comment Period for Constitution Pipeline and Wright Interconnect Projects
FERC has launched a new environmental scoping and public comment period for the Constitution Pipeline and Wright Interconnect projects through May 2026.

United StatesUS BLM Proposes NEPA Categorical Exclusion for Forest and Woodland Density Management Up to 5,000 Acres
The US Bureau of Land Management proposed a new NEPA categorical exclusion to significantly streamline environmental reviews for forest density management projects up to 5,000 acres. This move reflects a broader federal push for permitting reform, reducing administrative delays for land management activities and potentially accelerating resource-related operations on federal lands.
United StatesUS NGOs Urge FCC To Require NEPA Review Of Reflect Orbital Sunlight-Reflecting Satellite
Environmental groups are petitioning the FCC to mandate formal environmental impact reviews for sunlight-reflecting satellites, citing risks to biodiversity and public safety. This challenge signals a shift toward stricter permitting and photobiological safety standards for orbital lighting, creating significant regulatory hurdles for space-based geoengineering projects.
United StatesUS NRC Final Rule Amends Categorical Exclusions From Environmental Review (10 CFR Part 51)
The US Nuclear Regulatory Commission has expanded categorical exclusions under NEPA, effective April 29, 2026, to streamline environmental reviews for nuclear licensing and administrative actions. This deregulatory shift reduces administrative burdens and transaction costs for operators by exempting routine activities like security upgrades and spent fuel storage changes from lengthy environmental assessments.
United StatesUS Congress Introduces Protect American AI Act of 2026 For Data Center Environmental Permits
The U.S. House introduced the Protect American AI Act in March 2026 to streamline environmental permitting and judicial review for data centers and AI infrastructure. This legislation would significantly reduce project risk by preventing permit vacatur during litigation and shortening legal challenge windows for critical digital infrastructure investments.
United StatesUS NRC Issues Draft EIS and Seeks Comment on Paducah Laser Enrichment Facility
