The sulfur services segment has expanded significantly by developing an integrated system of transportation assets and facilities relation to sulfur services. Today, we process and distribute sulfur produced by oil refineries primarily located in the United States Gulf Coast region. At our facilities in California and Texas, we process molten sulfur into formed solid sulfur. The sulfur we process is primarily used in the production of fertilizers and industrial chemicals. We own and operate six sulfur-based fertilizer production plants and one emulsified sulfur blending plant. These plants are located in Illinois, Texas and Utah. We also own and operate a sulfuric acid production plant, which processes molten sulfur into sulfuric acid, and an ammonium sulfate plant, both located in Plainview, Texas.
