The Federal Energy Regulatory Commission (FERC) has issued a formal notice outlining the schedule for the preparation of an environmental assessment (EA) for the 2025 Amendment Project, a proposed natural gas storage project in Millard, Juab, and Utah Counties, Utah. The project, submitted by Magnum Gas Storage, LLC, seeks to amend the existing Certificate of Public Convenience and Necessity to modify previously approved facilities and construct new ones, increasing the working gas storage capacity by 20.8 billion cubic feet. The EA will be issued on November 13, 2025, and will be subject to a 30-day comment period. The EA will address concerns raised by two landowners, including impacts to adjacent land use, property rights, and lack of adequate project information.
