San Joaquin County Environmental Health Department �a 1868 East Hazelton Avenue, Stockton, California 95205-6232 Telephone: (209)468-3420 Fax: (209) 468-3433 Web:www.sigov.org/ehd Underground Storage Tank Program Inspection Report Facility Name: Facility Address: Date: CRUISERS MANTECA#29 1 1137 W LATHROP RD, MANTECA August 25, 2016 SUMMARY OF VIOLATIONS (CLASS I,CLASS II,or MINOR-Notice to Comply) Item# Remarks 305 HSC 25290.1(e)VPH monitoring of the interstitial spaces of the UST system is not maintained. The following was noted at the time of inspection: 1)An active brine leak was noted from the diesel fill sump wall around the brine sensor holder, indicating a breach in the secondary containment; standing liquid was also observed inside this sump. Secondary containment shall be impervious to the liquid and vapor of the substance contained and constructed to prevent structural weakening as a result of contact with any hazardous substances released from the primary containment. Furthermore, per the Service Station System maintenance record, dated 5-24-2016, "repairs to the leaking annular to be done by LC Services-adjusted brine on L5 sensor"; L5 is a sensor located inside the diesel STP sump. Immediately contact a properly licensed, trained, and certified contractor to make repairs to the UST system (specifically diesel fill and STP sumps) under permit and inspection of the EHD. 2) The 87 annular sensor(S3) sensor (liquid sensor) failed when tested. The sensors monitoring the interstitial space shall be maintained so that a breach in the primary or secondary containment is detected before the hazardous substance is released into the environment. The sensor was cleaned and retested during the inspection with passing results. This was corrected at the time of inspection. 3) The following sensor holders had very little or no evidence of brine presence: UDC#6, UDC#7, UDC#9, UDC311, and 91 STP, and diesel STP sumps, all these sensors were tested with passing results at the time of inspection. Sensor L14 (UDC#7)went in low liquid alarm prior to its testing at the time of inspection (due to low brine levels).The following sensor holders were also placed very low in relation to the sump top (brine sensors were located 10-12-inches below UDC tops) in addition to having little or no brine in their respective sensor holders: UDC#6, UDC#7, and UDC#11. The liquid level in the interstitial space shall be maintained so that a breach in the primary or secondary containment is detected before the hazardous substance is released into the environment. At the time of inspection, brine was added to all above sensors and sensor holders adjusted by the technician onsite. Furthermore, recurring"low liquid' alarms were observed throughout the year for the L2, L3, L4, and L5 sensors, investigate the cause of the recurring low liquid brine alarms and correct(as needed) by having a properly licensed, trained, and certified contractor replace the failed component with a functional component(LG 113-x listed, if applicable) and obtain a permit within one business day from the EHD. Submit proof of correction to the EHD. This is a Class II violation. 306 CCR 2630(d) Monitoring equipment is not installed or maintained to detect a leak at the earliest opportunity. The diesel STP sump sensor was located approximately 3 inches off the lowest point of the sump (up the sump saddle) and not located to detect a leak at the earliest opportunity, liquid (<1 gallon) was also noted in this sump. Monitoring equipment shall be maintained to be able to detect a leak at the earliest possible opportunity. The sensor was relocated to the lowest point of the sump by the service technician. Ensure that all monitoring equipment is maintained to detect a leak at the earliest opportunity. This is a repeat violation, Class II. Page 5 of 7
