The proposed Revised Final Supplemental Environmental Impact Report (SEIR) is available for public review. The SEIR was updated after its initial release in July 2020 to address the planned shutdown of the Phillips 66 Santa Maria Pump Station (SMPS), one of two trucking destinations for the proposed project. Shutdown of the SMPS during the lifetime of the proposed project would require that all crude oil be transported to the Plains Pentland Terminal once the SMPS is out of service. In addition, the SEIR was updated to address new transportation impact thresholds, and also includes other minor modifications and editorial updates. None of these updates result in any new environmental impacts, nor change the severity of any of the impacts identified in the previous proposed Final SEIR.

Staff analysis of the proposed project is available in the Planning Commission Staff Report. Virtual hearings before the Planning Commission to recommend project approval or denial to the Board of Supervisors are scheduled for September 29, and October 1, 2021. To provide written comments to the Planning Commission, submit your comment via email to the Project Planner, Jacquelynn Ybarra by September 24th, or else to the Recording Secretary, David Villalobos at prior to 12:00 pm on September 27th. Your comment will be placed into the record and distributed to the Planning Commission.

The Project would initiate the phased restart of the existing ExxonMobil Santa Ynez Unit (SYU) facilities by trucking limited crude oil production to receiver sites in Santa Maria and Maricopa, as a temporary solution to transport crude oil to a refinery destination until a pipeline alternative becomes available. Trucking would occur seven days per week, 24-hours per day, with no more than 68 - 70 trucks leaving the Las Flores Canyon (LFC) facility within a 24-hours period to one or both of the two receiver sites. The project would include minor modifications to the LFC facilities including the installation of four Lease Automatic Custody Transfer Units, associated piping, electrical and communication connections, pipe and equipment supports, truck loading racks, operator shelter, paving of selected areas, and minor containment and drainage grading.
