Document Description
Request by Chevron Environmental Management Company for Development Plan/Coastal Development Plan (DRC2019-00069) to amend previously approved Development Plan/Coastal Development Plan (D890558D) for the Guadalupe Restoration Project, to construct and operate a Soil Management Area (SMA) for handling hydrocarbon affected soil that are generated as part of the ongoing restoration activities at the former Guadalupe Oil Field. The proposed SMA will be placed at the T-9 site, which currently has a large sump. The sump would be excavated prior to construction of the SMA as part of the ongoing Guadalupe Restoration Project. When completed, the SMA would be re-vegetated with Coastal Dune Scrub. The SMA is estimated to take approximately three to five years to complete. The project would disturb approximately 18 acres of previously disturbed area on a 939-acre parcels (092-041-001 & 092-041-005), including 1.2 million cubic-yards of earthwork. The project is located at 2184 West Thornberry Road, approximately 5 miles southwest of community of Nipomo, in the South County Coastal Planning Area.
