A Reliable Supply of Natural Gas for the Salt Lake City Area

HDR served as owner’s engineer for Dominion Energy Utah on its Magna Liquefied Natural Gas facility. The LNG facility provides customers with a steady, reliable flow of gas to homes and businesses.

Historically, Dominion Energy Utah sources about half of the natural gas sold to retail customers from company-owned supplies, which are typically more stably priced than gas purchased from other suppliers. Magna LNG facility liquefies gas at a rate of 8.2 MMscfd (100,000 gallons per day) and stores it in a 15-million-gallon storage tank. When demand is high, LNG is vaporized at a rate of 150 MMscfd.

Our role included:

• Assisting with site selection and conceptual design.
• Producing front-end engineering design (FEED) documents, including a site selection evaluation, preliminary engineering design (site layout, liquefaction and pretreatment technology selection), procurement specifications, contractor engagement, pre-filing of local and state regulatory permits, cost estimates and a project schedule. The FEED was used by the utility as the basis to file a rate case with the State of Utah Public Service Commission.
• Meeting with Salt Lake City planning and zoning boards, local fire marshal and landowners, and developing a public involvement action plan.
• Supporting the project through the Public Service Commission approval process.
