Background
The SMR Project site covers an approximately 218-acre footprint defined by a fenced boundary within approximately 1,650 acres of contiguous property held by Phillips 66. The property is south of, and takes access from, Willow Road, surrounded by Oceano Dunes State Park to the west, agriculture uses to the south, Woodlands Village Reserve (Monarch Dunes) to the east, and Callendar-Garrett Village Reserve and agriculture use to the north. The SMR property is within the Coastal Zone; parcel Land Use designations include Industrial, Open Space, and Agriculture.
The Santa Maria Refinery has been in operation since 1955 producing semi-refined liquid petroleum, as well as petroleum coke (carbon) and granular sulfur which are by-products of refining. The crude oil for processing was delivered primarily by pipeline from offshore platforms along the California coast and oil fields in and near the Santa Maria Valley. Approximately 2,000 barrels per day of petroleum-based crude product was delivered to the refinery by truck. Semi-refined liquid products from the SMR were transported by pipeline as feedstocks to the Rodeo Refinery in Contra Costa County, California, for upgrading into finished petroleum products. The petroleum coke was shipped to off-site market destinations by rail and truck and the granular sulfur was shipped to off-site market destinations by truck.
Phillips 66 recently obtained approval to transform the Rodeo Refinery, located in the community of Rodeo, in Contra Costa County, into a repurposed facility that will process renewable feedstocks into renewable diesel fuel, renewable components for blending with other transportation fuels, and renewable fuel gas. Because the Rodeo Renewed Project will discontinue the processing of crude oil at the Rodeo Refinery, the SMR is no longer necessary to provide feedstock to the Rodeo Refinery. Consequently, Phillips 66 ceased operations of the SMR in January, 2023.
Notice of Preparation
On May 4, 2023, the County issued a Notice of Preparation, which is a notice for soliciting agency, organization, and public input and initiation of scoping for the preparation of an Environmental Impact Report (EIR) for the Phillips 66 Santa Maria Refinery Demolition and Remediation Project.
