B.Worst Case Discharge Analysis and Scenarios Version :27.10.4 . There are no berms across the Facility's entrance gate, thus the diesel fuel 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 Prevention Several steps can be taken to limit the number of occurrences and the amount of discharges. In particular, employees receive training periodically on the proper procedures for the loading of product to trucks and railcar. In addition, preventive maintenance of equipment is performed at regularly scheduled intervals to ensure that any weaknesses are discovered. Also, old or worn parts are replaced as needed. Annual product transfer and pipeline testing is the most important of these measures. While the Facility's OSRO or spill contractor would be notified and the best method for containment determined, such discharges that are contained at the Facility could be diverted to the product tanks that are not at maximum capacity. 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 San Joaquin River. Therefore, the threat to sensitive areas (see Section 6 and Appendix C) is minimal. Finally, this type of spill is not one that would result in a chain reaction of failures of other equipment and would not be adversely impacted by normal Local Weather conditions due to the size and controls on site. Response Requirement The Facility shall identify sufficient resources, by contract or other approved means, to respond to a Small Discharge. The response resources shall, as appropriate, include: • 1,000' of containment boom and a means of deploying it within one (1) hour of the discovery of a spill. . Oil recovery devices with an effective daily recovery capacity (50 bbls/day) equal to the amount of oil discharged in a Small Discharge which is available at the Facility within two (2) hours of the detection of an oil discharge. . Oil storage capacity (100 bbls)for recovered oily material equivalent to twice the effective daily recovery rate.
