OmniTRAX Inc. today announced it has signed a long-term rail switching agreement for Church and Dwight Co. Inc.'s pharmaceutical-grade sodium bicarbonate production facility in Green River, Wyoming.
Built in 1968, the Green River facility produces Arm & Hammer baking soda where the trona ore is mined. Wyoming is home to 90% of the world’s trona ore deposits, OmniTRAX officials said in a press release.
Trona is a sodium carbonate compound that is processed into soda ash or bicarbonate of soda, or baking soda, as it is commonly known, according to the Wyoming Mining Association. Church and Dwight is the largest baking soda producer in the United States and parent company of many household name products, including Arm & Hammer, OminTRAX officials said.
OmniTRAX will provide dedicated switching service for the Green River facility, which operates 24 hours a day. Financial terms of the agreement were not disclosed.
The new switching agreement marks OmniTRAX’s third Green River operation added in the past year, company officials said.
“Arm & Hammer is an iconic American brand and OmniTRAX is proud to provide the safe and reliable rail service to keep Church and Dwight’s Green River facility moving smoothly,” said OmniTRAX CEO Colby Tanner.
