Explore product storage at Sawtooth Caverns.

Sawtooth’s underground salt cavern storage facility, located near Delta UT, is connected to key logistics infrastructure including the Union Pacific Railroad, and the interstate highway system just off I-15 which connects Salt Lake City to Las Vegas.

See elements of the infrastructure using the map legend below.


Sawtooth’s facility is actively loading, off-loading, and storing NGL products.  We offer a range of pressurized NGL products storage including multiple grades of Butane and HD5 Propane. 

Our railcar storage capacity is 280 railcars, and we have 28 offload and loading spots, allowing us to efficiently load 100 railcars in under 24-hours. Sawtooth’s rail facilities were also designed to accommodate growth with room to expand thereby increasing our railcar capacity.

Our NGL products facilities receive trucks from the adjacent interstate highway system. We offer four (4)  truck loading lanes, and six (6) off-loading lanes.  Additionally, our in-line propane dehydration system insures all product loaded at our facility meets moisture specifications.

Refined Products

In Spring 2021, we completed our Phase 1 (Truck) refined products expansion of our facility, which added a two-bay truck rack with dedicated staging tanks and injection capabilities.  Our Phase 2 (Rail) refined products expansion was completed during Summer 2022.  Phase 2 provided Sawtooth with the capability to offer rail (UPRR) off-loading and loading of refined products and feedstocks, along with enhancing our railcar storage capacities.  The Phase 3 (EtOH) refined products infrastructure was completed in early June 2023 and added a dedicated Ethanol blending rail rack and supporting railcar storage.      

Sawtooth’s new rail and truck racks accommodate the off-loading and loading of railcars and trucks containing Gasoline, #2 ULSD, Jet Fuel, and other refinery feedstocks into cavern storage.  In addition, Sawtooth’s new infrastructure can also be utilized to directly transload those same products from Rail-to-Truck, or Truck-to-Rail. This will enable our customers to address market volatility, seasonal demand variability, arbitrage opportunities, and turnaround challenges by adding refined products storage, blending, and transload capabilities.
