Document Description
The County of San Luis Obispo has prepared a draft Environmental Impact Report for the project: a request by Phillips 66 for a County Major Grading permit (PMTG2019-00065) for excavation of hydrocarbon-impacted soils at varying depths and widths within two affected areas along an existing oil pipeline alignment. The proposed work will be consistent with the project Corrective Action Plan (CAP), including backfilling the excavations and restoration of the site to current grade. The remediation project will result in the disturbance of approximately 20 acres, including approximately 87,046 cubic yards of cut and 96,023 cubic yards of fill material on the 899-acre parcel (APN 070-091-036). The project site is located at 9295 Yerba Buena Avenue, on a portion of the Santa Margarita Ranch located north of the community of Santa Margarita between US Highway 101 and El Camino Real. The proposed project is within the Agriculture land use category in the Salinas River Sub Area of the North County Planning Area. The project will result in Class I significant and unavoidable impacts to cultural and cultural tribal resources. Issue areas including Air Quality, Biological Resources, Geology & Soils, and Transportation will result in Significant but Mitigable Impacts. Impacts to all other issue areas evaluated are less than significant.
