A large chemical plant that produces chlorine, fertilizer components, and potassium carbonates and bicarbonates, which are used in products such as detergent, chocolate, and fire extinguishers. Partially operated by Church and Dwight (the makers of Arm and Hammer baking soda, which was owned by the homonymous industrialist Armand Hammer) and OxyChem, the chemical division of Occidental Petroleum. OxyChem is a leading producer of these chlor-alkali products, and this plant is the nation's largest producer of caustic potash.
