The following is an itemized list of underground storage tank violations that have not <br /> been addressed for Arco. Am pm 83333 as of May 14, 2017. <br /> Open violations from October 26, 2016 inspection <br /> Violation #305 -VPH monitoring of the interstitial spaces of the UST system is not maintained. <br /> -The brine levels in the vent sump were several inches below the top of the sump-the technician added brine at the <br /> time of inspection. Records on site show that brine was added to all UDC sumps on 10/13/16. <br /> -The brine sensors in the UDC interstitials were placed at the bottom of the brine reservoirs, approximately 8 inches <br /> below the liquid levels, and not located to detect a leak at the earliest opportunity. <br /> -The communication inside the fill and STP sumps(6 sumps total)was not tested during today's inspection and <br /> could not be verified functional. <br /> The sensors monitoring the liquid level in the interstitial space shall be maintained so that a breach in the primary or <br /> secondary containment is detected before the hazardous substance is released into the environment. Ensure that <br /> monitoring of the interstitial space is maintained at all times and that all potential leaks are properly addressed. <br /> Immediately schedule for verification testing of the sump interstitial communication (all EHD staff time associated <br /> with this reinspection will be billed at the current hourly rate). If alterations will be made to the sumps to allow for <br /> easier communication testing, they must be done under permit and inspection of the EHD. <br /> Violation #316 -Secondary containment not constructed to prevent water intrusion (after Jul 2003). <br /> Water was found in the 91 STP sump, diesel STP sump, and 87 fill sump. Secondary containment shall be <br /> constructed to prevent any water intrusion into the system by precipitation, infiltration, or surface runoff. The service <br /> technician removed the liquid from the sumps and returned the sensors to their proper location. Immediately <br /> contact a properly licensed, trained, and certified contractor to address the water intrusion into the 91 STP sump, <br /> diesel STP sump, and 87 fill sump under permit and inspection of the EHD. <br /> Page 1 of 1 <br />
