All monitoring equipment used to satisfy the <br /> requirements of this article shall meet the requirements of section 2643(f) and shall be <br /> installed and maintained such that the equipment is capable of detecting a leak at the <br /> earliest possible opportunity. Additionally, all monitoring equipment used to satisfy the <br /> requirements of this article shall be installed, calibrated, operated, and maintained in <br /> accordance with section 2638. <br /> 4 During the September 4, 2012, UST inspection, it was found that the 87-octane <br /> slave UST annular sensor had been in alarm since September 1, 2011, and no <br /> actions have been taken to address the alarm. <br /> T23, CCR 2631(a) Primary containment is product tight. All new underground <br /> storage tanks including associated piping used for the storage of hazardous substances <br /> shall have primary and secondary containment. Primary containment shall be product- <br /> tight. Secondary containment may be manufactured as an integral part of the primary <br /> containment or it may be constructed as a separate containment system. Secondary <br /> containment systems shall be designed and constructed such that the secondary <br /> containment system can be periodically tested in accordance with section 2637(a). <br /> 4 Diesel fuel was found in UDC sumps 5/6 and 9/10 during the July 23, 2008, UST <br /> inspection. <br /> 4 Diesel was found leaking at the filters at dispensers 5/6 and 9/10 during the July <br /> 28, 2010, UST inspection. <br /> -> Diesel was found leaking at the filters at dispensers 5/6 and 9/10 during the <br /> September 28, 2012, UST inspection. <br /> T23, CCR 2632(b) Monitoring program (Monitoring and Response Plans) is <br /> current and approved by the local agency. Owners or operators of underground <br /> storage tanks subject to this section shall implement a monitoring program approved by <br /> the local agency and specified in the underground storage tank operating permit. The <br /> program shall include interstitial space monitoring as described in subsection (c) and <br /> shall include the items listed in subsection (d). <br /> 4 Monitoring and response plans were not current at the time of the July 23, 2008, <br /> UST inspection. <br /> T23, CCR 2632(c)(2) Monitoring system not present in the interstitial space of a <br /> double walled UST. A monitoring program which relies on the mechanical or electronic <br /> detection of the hazardous substance in the interstitial space shall include one or more <br /> of the methods in Table 3.2. The following requirements shall apply when appropriate: <br /> (A) The interstitial space of the tank shall be monitored using a continuous monitoring <br /> system which meets the requirements of section 2643(f). <br /> (B) The continuous monitoring system shall be connected to an audible and visual alarm <br /> system approved by the local agency. <br /> (C) For methods of monitoring where the presence of the hazardous substance is not <br /> determined directly, for example, where liquid level measurements in the interstitial <br /> space are used as the basis for determination, the monitoring program shall specify <br /> the proposed method(s) for determining the presence or absence of the hazardous <br /> substance in the interstitial space if the indirect methods indicate a possible <br /> unauthorized release. <br /> 16 <br />
