• APPENDIX B - Page 12.2 <br /> REVISED TANK MONITORING PLAN <br /> INTRODUCTION <br /> The Office of the State Architect has developed the following Tank Monitoring <br /> Plan (TMP) as required by Title 23 Waters, Subchapter 16 Underground Tank <br /> Regulations from the California Code of Regulations. The TMP has been <br /> prepared to comply with the Local Enforcement Agency guidelines for leak <br /> detection and monitoring alternatives. <br /> SITE DESCRIPTION <br /> This site is operated by the California Department of Developmental Services <br /> for the State of California. This site is located at: <br /> Stockton Developmental Center <br /> 510 East Magnolia Street <br /> Stockton, California 95202 <br /> (209) 948-7411 <br /> Eight tanks at this facility are proposed for the installation of tank level <br /> monitors. A brief overview of the tank information is presented below: <br /> O.S.A. ID NO. CAPACITY MATERIAL INSTALLED CONTENTS <br /> D-SDC-01 10,000 gal . Steel Unknown Diesel <br /> D-SDC-02 10,000 gal .

Steel Unknown Diesel <br /> D-SDC-07 10,000 gal . Steel Unknown Regular <br /> O-SDC-08 1 ,000 gal . Steel Unknown Unleaded <br /> Plot plate SK-12-1 shows vicinity plan of the tanks. Plot plates SK-12-2 and <br /> SK-12-3 show plan view of the tanks. <br /> TANK MONITORING PLAN (TMP) <br /> The TMP outlined below is based on the Local Enforcement Agency guidelines and <br /> utilizes tank level monitoring. The Tank Level Monitoring (TLM) System will <br /> be installed at this facility. The TLM is an automatic system used for <br /> inventory reconciliation within an underground storage tank. The TLM refers <br /> to probes, monitoring consoles, alarms and other appurtenant devices . A <br /> measuring probe will be located inside each underground storage tank to <br /> automatically measure the level of the liquid, and hence, the volume, stored <br /> in the tank. The probe will be connected to a monitoring console, audible and <br /> visual alarms and recorders. The TLM will also have the capabilities to <br /> perform a tank integrity test, activate a high level alarm, automatically <br /> alert a remote monitor and measure the water level in the tank. Specific <br /> details of the TMP are listed below: <br />
