Our asphalt plant in Santa Maria, California produces light naphtha, kerosene distillate, gas oils and numerous cut-back, paving and emulsion asphalt products. Demand for our asphalt products is primarily in the Central and Northern California regions, while naphtha and distillates are sold throughout California.

Since the 1930's the refinery has essentially been running 24/7, 365 days a year. It has always had demand for its full output at market prices. Prior to selling the refinery in 1994, Conoco ran the refinery for 48 years at an output of approximately 10,000 barrels per day. Asphalt specifications have advanced significantly over the last 10 years and will continue to be pushed forward requiring varying degrees of modification with natural rubber, ground tire rubber, polymers and other additives. In an attempt to improve the overall quality of the highways throughout the United States, the Federal Government since the 1990's developed a performance-grade (PG) rating system for the quality of asphalt and its use in various climatic conditions. California follows these guidelines requiring asphalt manufacturers to conform to a tight set of specifications. Greka’s refinery is certified to produce the various PG-grades utilizing our local crude supply. Santa Maria Valley crude oil has the physical properties that yield high quality asphalt with a high susceptibility to the various modifiers, and our staff has experience in making all the currently known formulations. We have delivered product to high-margin niche markets and anticipate this opportunity will continue to grow. Greka has marketed its premium asphalt products primarily in Central California. The Central Coast is geographically isolated from other California asphalt producers which are located in San Francisco, Bakersfield and Los Angeles. Greka has a distinct freight advantage in the local market extending from the South San Francisco Bay area to Ventura.
