asphalt plant in Santa Maria, California produces light naphtha, kerosene distillate, gas oils and numerous cut-back, paving and emulsion asphalt products. Historically, marketing efforts were focused on the asphalt products that are sold to various users, primarily in the Central and Northern California regions. Distillates are readily marketed to wholesale purchasers. The refinery’s permitted capacity is 10,000 barrels per day. The original refinery, built in 1932-33 by The Five C Refining Company, was a simple facility that produced naphtha, kerosene distillates, diesel fuel and residuum from oils extracted in the region. Some of these products may have been further refined by others into motor gasoline, heavy oils for power generation and marine fuel for large vessels. The refinery as originally constructed did not have the capability to produce asphalt.
