Stockton Soda Infinity Railroad Loop and Bulk Terminal

The Stockton Soda project is an initiative to replace carbon-intensive, higher-cost synthetic soda ash production overseas with natural domestic production. Soda ash is a key component in the clean economy, as it is used in the production of numerous energy transition products. This includes solar panels, energy-efficient windows, EV batteries, and solid-state renewable energy storage. The project site repurposes land and structures formerly utilized by the U.S. Navy and Port of Stockton tenants.

The Stockton Soda Ash Port (SSAP) facility, in the Port of Stockton, will enable a supply chain that connects the soda ash reserves near Green River, WY, to global markets via Union Pacific Railroad unit trains and cargo ships.

The terminal will ultimately handle vessel loads ranging from 28,000 to 34,000 metric tons and 193-car trains with a capacity of 19,300 tons of soda ash. The project will incorporate the latest automation, handling with conveyors, and storage/reclaiming technologies to enable safe, efficient materials management.

As a major subconsultant, Hill is providing project and construction management for multiple components of the Stockton Soda project. This includes:

• The Infinity Railroad Loop: This new proprietary railroad loop track will facilitate the handling of 193-car trains, significantly optimizing the unloading process with a cycle of just 24 hours.
• High-capacity Rail Car Unloading Building (RCUB) and Conveyor System: This storage facility will enable the transfer of large volumes of soda ash efficiently, reducing the time for unloading, storage, reclaiming and ship loading.
• Stacker/Reclaimer Building for storage and recovery of soda ash to buffer train-to-ship loading.
• Administration and Control Buildings to operate the facility.
• Advanced water-tight conveyor system and wharf mounted ship loader.
