Notice to Facilities with Emergency Power Generators Supplied from USTs
On April 4, 2013, an Emergency Rule Change went into effect in Illinois which affects facilities with Emergency Power Generators which are supplied with fuel from underground storage tanks (USTs). Prior to that Emergency Rule Change, all USTs were required after September 1, 2010 to have interstitial monitoring sensors immediately shut off the submersible pump in pressurized piping systems or the suction pump in American suction systems. When this requirement is applied to Emergency Power Generators, though, which primarily are installed at facilities which must maintain services during power outages, such as hospitals, airports and communication centers, all power would be lost to the facility if a sensor was activated. Additionally we saw that automatic line leak detectors installed on pressurized piping could also be programmed to shut off submersible pumps if they were electronic line leak detectors, or restrict fuel flow if they were mechanical line leak detectors. Neither the pump shut off nor the flow restriction can be allowed to occur at a critical services facility maintaining operations with their Emergency Power Generator during a power outage.
Having identified the problem, we set about to correct the situation. Prior to filing the Emergency Rule Change, staff in the Division of Petroleum and Chemical Safety in the OSFM started contacting UST contractors and owners of facilities where our database showed an Emergency Power Generator had been worked on since September 1, 2010. That was the date the original regulation went into effect. This was done statewide. Language for the Emergency Rule Change was crafted by legal, technical and senior staff at OSFM and Petroleum and Chemical Safety. At the time the Emergency Rule Change was filed, notification went out by mail to all OSFM licensed contractors and the contact identified at each facility on our list, and this Notice was posted at our website. Rule Policy/Interpretation 13-PCS-001 was included with the notification letters, and was also posted at our website on the Commercial page.
