Document Description
U.S. Borax produces between 30,000 and 50,000 tons per year (tpy) of trona at the Owens Lake location. The upgraded facilities would allow increased production to 144,000 typ, including washed trona, dry sized trona, and calcined trona at 95 percent conversion (i.e., chemically converted through heat). The calcined trona (calcine or soda ash) and a portion of the washed trona would supply U.S. Borax's Boron Operations to reduce the need for purchase from outside sources. The proposed project would also allow Borax to continue selling washed and dried trona directly to commercial customers. Future mining would continue to take place within the existing mining leasehold via the panel-mining method. Project implementation would not increase the area to be mined beyond that already leased.
