HollyFrontier Closes Acquisition of Puget Sound Refinery

We are committed to the continued safe and environmentally responsible operations of the facility and welcome Puget Sound’s highly skilled workforce to the HollyFrontier family.”

The Puget Sound Refinery is strategically located on approximately 850 acres in Anacortes, Washington, approximately 80 miles north of Seattle and 90 miles south of Vancouver. The 149,000 barrel per day facility is a large, high quality and complex refinery with catalytic cracking and delayed coking units and is well positioned geographically and logistically to source advantaged Canadian and Alaskan North Slope (“ANS”) crudes.

In addition to refining assets and an on-site cogeneration facility, the transaction includes a deep-water marine dock, a light product loading rack, a rail terminal, and storage tanks with approximately 5.8 million barrels of crude, product and other hydrocarbon storage capacity.

HollyFrontier was represented by Morgan Lewis & Bockius LLP, Wachtell, Lipton, Rosen & Katz and Marten Law LLP on this transaction.
