It is your responsibility to oPerAe this product according to the 11 R] 0 This manual describes operating procedures for the EMC Environmental Management Console manufactured for GlIbstoo Ina., 7800 W. Friendly Ave.. Greensboro, NC 27420. When a verticah bar I appears adjacent to text or itlua;tratious, information has been added or revised to this printing. . 'tire instructions In this manual describe the procedures to operate All of the monitoring and control functions that can be installed in an EMC. The exact functions installed in the system you are operating were selected according to the Monitoring and control requirements of your site. They can vary 13 nm system to system IF SOME FUNCl'DONS WERE NOT INSTALLED IN YOUR SyS'CEM, the system will skip those functions during the operating process. in order: to correctly and effectively operate this system, YOU M06T SNOW what inventory monitoring, leak detection, alarm and data communications functions have been L -`stalled. SECTION 2. PRODUCT DESCRnMON The EMC is an advanced. fully integrated Tank Information on System that can provide Complete inventory n !fret stored in underground tanks and can warn of leaks from these tanks. TO to 1209SB33282 F•04 I. Monitoring Functions Monitoring functions such as inventorycontrols sensing ant -' detection. interstitial leak sensing. groundwater vapor sensing are provided by in -tank probes, interstitial sensors located between the walls of double-wall tanks, sensors in the sumps of double-wall Piping systems. sensors in dispenser pans and containment sumps, and sensors to vapor skAd groundwater monitoring wells. Tile system you are operating may have a combination of these functions installed. 2. Continuous Statistical Leak Detection (CSLD) CSLD is an advanced tank tearing technology that makes trill use of the SSC in -tank monitoring cstpab8ities. The EMC with CSLD eontinuously monitors fuel height. *Ad temperature information to detect idle times in the tank. During each idle tune, data are collected and combined with Information from other idle periods to form a highly accurate teal( detection database. Sophisticated statistical analysis techniques in CSLD constantly evaluate all new and aU, existing information in the database to discard invalid data and perform leak tests based on only high-quality information in the current database A new leak test is performed every time new data itrom an idle period is added. Since the database is constantly being updated. leak test results are always current. Leak tests are performed using the best data Brom up to the previous 28 days, and tests results are continuously updated as new data are gathered. Test results are provided automatically every 24 hours. in addition, up-to- the-minute leak test results are available at any time with the press of a button. CSLD,s algorithm sorts through all available information and uses only the highest quality data to perform its leak tests. Invalid data is thrown out and only the best data is used for accnrrate leak test results and legs chance of Use alarrtta. Because leak test data is collected continuously and updated frequently, the response time to detect leaks is shorter than that of scheduled static leaf( testa Third -party testing confirmed that CSLD meets Federal, state and local compliance requirements for monthly monitoring. Test results showed a 9996 probability of detection and less than a 0.1% chance of false alarm. That far exceeds the U.S. E.P.A. performance standards of 06% probability of detection and 6% probability of false alarm A. MONITOR FEATti&ES =on on of the system is performed using buttons and the the EMC monitor front panel (see Figure 1,"EMC Fxont Panel Features"). Depend!09 on the features your system is equipped with, you can read or print inventory data, review teak test results and system status information, and start and stop in -tank leak tests. The EMC monitor includes the following features (see Figure 1, "EMC Front Panel Featuresl: • A two-Une, 24-character-per-tlne liquid crystal display. • A 24 -button keyboard with the operating and data entry functions used to display Information, print reports and start and stop leak test$_ • Three lamps to provide power -on, warning and alarm Indications. • An audible warning and alarm indicator. • An optional printer to provide inventory, leak test, and alarm reports. S. Line Leafs Detection The EMC Line Leak Detector Is capable of performing volumetric leak tests on pressurized lines to identify leaks at test rates of SA gallons per hour (GPH), 0.2 GPH and 0.1 GPH.
