I. Introduction The following surveillance and inspection procedures are designed to prevent oil -spills and to prevent oil from entering navigable waters if a spill occurs. Oil spill inspection activities (tank filling operations) and discharge incidents will be recorded in writing and signed by the appropriate supervisor or operator. These records will be attached to the SPCC plan and stored for a period of three years. In addition, the surveillance and Inspec- tion results will be reviewed by the designated person accountable for oil spill prevention. II. Tank Leak Testing Oil storage tank leaks, if any, will be identified in one of two ways. First, the tanks will be monitored daily for product leak- age using an in -tank precision product monitoring system. Second, the tanks will be leak -tested by a licensed contractor on an annual basis using the "petro -tate" or equivalent testing technique, to determine container integrity. Immediate action will be taken to determine the cause of any test failure and to initiate appropri- ate corrections. The following paragraphs describe the precision product monitoring system and the procedures for its use: 1. Precision Product Monitoring System Because of underground tank orientation and facility staffing daily manual inventory control monitoring of diesel fuel and long term tank monitoring for product leakage will be accom- plished using in -tank precision product monitoring. This will be provided through the installation of the TLS -250 Tank Level Sensor manufactured by Veeder-Rooter, a subsidiary of Western Pacific Industries Corporation or equivalent. A TLS -250 system consists of a Computerized Inventory Monitor (CIM) and one Digital Sending Probe (DSP) for each tank being monitored. The highly accurate, all -electronic probe has no moving parts for greater accuracy and less maintenance than other electromechanical, float -type devices. A single CIM can handle four probes and continuously monitor each one, analyzing their signals for liquid, temperature, depth, and water level. Based on this input, the CIM computes volumes, and stores this information for remote polling. The RS -232C Serial Interface Communications port permits access to the TLS -250 information from remote locations via telephone lines. The TLS system has three modes of operation - Leak Detection, Tank Inventory, and Automatic Delivery Reporting. When the leak monitor mode is activated, the TLS System continuously monitors fuel levels in each tank and can detect small RKE717P1428532
