Regulatory Information

Department of Energy

In April 2022, DOE’s Loan Programs Office issued a conditional commitment for ACES I. The loan closed on June 3, 2022, highlighting the Administration and the Energy Department’s commitment towards supporting the clean hydrogen sector. This loan helps generate a viable market for hydrogen and will make it scalable in the western United States and electrical grid, creating the fundamental infrastructure necessary to deploy this zero-carbon energy source. The hub will initially be designed to convert renewable energy through 220 MW of electrolyzers to produce up to 100 metric tonnes per day of green hydrogen, which will then be stored in two massive salt caverns each capable of storing 150 GWh of energy. Financed with support from the DOE loan guarantee, this facility will supply hydrogen feedstock to the Intermountain Power Agency’s (IPA) IPP Renewed Project — an 840 MW hydrogen capable gas turbine combined cycle power plant — that will initially run on a blend of 30 percent green hydrogen and 70 percent natural gas by volume starting in 2025 and will increase to 100 percent by 2045.

Federal Energy Regulatory Commission (FERC)

On March 17, 2011, the Federal Energy Regulatory Commission (FERC) issued an order granting Magnum Gas Storage a certificate of public convenience and necessity under section 7(c) of the Natural Gas Act (NGA) to construct and operate a natural gas storage facility and header pipeline. A copy of the FERC’s order can be found under Docket CP10-22-000 at

On November 16, 2015, Magnum submitted an Application for Amendment to request approval of facility site plan changes, a request for firm wheeling service, and an extension of the permit extension date. On March 30, 2016 a public open house was held in Millard County, Utah to hear public input on the Amendment request. A copy of the Amendment request can be found under Docket CP16-18-000 at

Bureau of Land Management (BLM)

On February 22, 2011 the Bureau of Land Management (BLM) issued a Decision Record granting Magnum Gas Storage a Right of Way Grant for the header pipeline. Magnum will construct and operate a 61.5 mile header pipeline from its storage facility near Delta to Goshen, Utah. A copy of the BLM’s Decision Record, Finding of No Significant Impact (FONSI) and Right of Way Grant can be found at

State of Utah

Magnum Gas Storage has been granted all necessary permits for construction and operation from the School and Institutional Trust Lands Administration, Department of Natural Resources and the Department of Environmental Quality. Copies of all state permits can be found on file with SITLA and other state regulatory agencies.

Millard County

On March 24, 2011 the Millard County Board of County Commissioners awarded Magnum the necessary Conditional Use Permits for the construction and operation of the Magnum Gas Storage Project. Copies of these permits can be found at the Millard County Planning Office located in Delta, Utah.

Environmental Compliance

Magnum is committed to maintaining environmental compliance during construction and operation of the Magnum Gas Storage Project. Information related to Magnum’s environmental compliance during Project construction will be available to the public via a third-party website. A hardcopy archive can also be accessed during construction at the Fillmore, Delta and Nephi public libraries.
