v <br />E <br />PACIFIC COMPANY <br />McDONALD ISLAND GAS <br />OIL -WATER SEPARATOR INFLUENT CONTROL PROCEDURE <br />Scope <br />This procedure provides guidelines for preventing harmful quantities of <br />hazardous substances from being discharged to the Oil -Water Separators <br />(OWS) at McDonald Island Gas Storage Facility. <br />me= <br />McDonald Island Gas Storage Facility includes the Turner Cut, Whiskey Slough, <br />and McDonald Island Platforms. Each platform has an OWS system that is <br />designed to collect non -hazardous runoff and wastewater drainage. The OWS <br />systems are located on ground level adjacent to the platforms and are connected <br />to the platforms via drainage piping. <br />The wastewater influent to the OS may contain traces of oil & grease, <br />triethylene glycol, and soil sediments. The influent has been tested and <br />confirmed to be non -hazardous in accordance with Title 22 of the California <br />Code of Regulations. To maintain the exemption from hazardous waste <br />treatment regulations, it is necessary to ensure that the OWS influent remains <br />non -hazardous. <br />Under normal facility operating conditions, the non -hazardous nature of the <br />OWS influent is not expected to change. However, if a hazardous substance <br />release occurs on a platform which could reach the OWS via drainage piping, <br />the influent could be adversely affected. If the release causes the influent to <br />become hazardous, the OWS could not be operated until the hazardous <br />substance was removed. <br />Procedure <br />1. Platforms should be inspected in accordance with the inspection schedule <br />specified in the facility's Hazardous Material Business Plan. <br />
