B.Worst Case Discharge Analysis and Scenarios Version:27.10.4 . There are no berms across the Facility's entrance gate or oil collection devices in the Facility's drainage system, thus the Transmix flows offsite, eventually to San Joaquin River through offsite storm water conveyances. . The San Joaquin River is the nearest waterway, located northeast of the Facility. This is the nearest fish, wildlife and sensitive environment. . The Facility would contact the contracted OSRO to have boom deployed within one (1) hour. . Oil recovery devices will be provided by the contracted OSRO within two (2) hours. In the event of a medium size discharge, the OSRO or spill contractor would be notified. While waiting for the OSRO to arrive, qualified Facility personnel would complete internal and external notifications. Diked area containment of large spills can be handled with the use of contractor vacuum trucks. Medium/maximum most probable discharges resulting from tank failure would more than likely be contained by the dike. The closest body of navigable water is San Joaquin River, which is northeast to Facility (see Section 6 ESMs). Appendix C, Section 6, and the ESMs in Section 6 describe and show locations of down gradient wells, waterways, drinking water intakes, fish, wildlife, and sensitive environments that are potentially impacted by any release offsite. The storage tanks and the truck/railcar loading areas have adequate secondary containment so it is unlikely that a spill would reach the San Joaquin River. Therefore, the threat to sensitive areas (see Section 6 and Appendix C) is minimal. A chain reaction of equipment failures of this magnitude would not be adversely impacted by normal Local Weather conditions due to the size and controls on site. Finally, the most likely chain reaction of failure would be fires resulting from accidental spark or downed power lines. Response Requirement The Facility shall identify sufficient response resources, by contract or other approved means, to respond to a Medium Discharge. The response resources shall, as appropriate, include: . Oil recovery devices with an effective daily recovery capacity equal to 50% of the Medium Discharge volume that is capable of arriving on scene within the required time limits. (See Recovery Times on Table B-1.) . Sufficient quantity of containment boom must arrive within the required time limits for oil collection and containment and for protection of fish and wildlife and sensitive environments, as appropriate. (See Recovery Times on Table B-1.) . Temporary storage capacity equal to twice the daily recovery capacity.
