Document Description
The Project consists of a request by Phillips 66 for a Development Plan/Coastal Development Permit to allow for the demolition and remediation of the Santa Maria Refinery (SMR), affecting approximately 218 acres of developed area within the 1,642-acre Phillips 66 owned property at 2555 Willow Road, Arroyo Grande. The Project includes aboveground demolition of refinery structures to ground level, followed by site characterization and soil remediation. Belowground infrastructure would be removed where necessary to accommodate removal of contaminated soils. After demolition and remediation, hardscape would be replaced where removed and exposed soil areas would be revegetated. At Project completion, features to remain include asphalt and concrete surfacing, perimeter fencing, electrical substation, water wells, truck scales, and two rail spurs, as well as monitoring wells and equipment associated with ongoing remediation under separate permits.
Aboveground demolition would take approximately eight months, followed by soil testing and remediation activities, which are expected to be mostly completed within three years; some remediation may continue for up to 10 years. The majority of demolition and remediation debris would be hauled offsite by rail, supplemented by trucks. Once remediation requirements have been met, site activities would be limited to restoration monitoring and general maintenance of the property and facilities. Potential future uses of the SMR site are unknown and are not considered as part of this Project.
