SAN J O A R N Environmental Health Department i y �V Underground Storage Tank Program Inspection Report Facility Name: Facility Address: Date: A&A GAS FOOD MART 1330 E YOSEMITE AVE, MANTECA November 03, 2021 SUMMARY OF VIOLATIONS (CLASS I,CLASS II,or MINOR-Notice to Comply) Item# Remarks 319 CCR 2635, 2637.2,2665, 2712 Failure to comply with overfill prevention equipment requirements. 1) OBSERVATION: The 87 and 91 tanks do not have an overfill prevention system. The facility's tank information form for all three tanks state that site is using ball floats as the only means of overfill protection. The facility has single walled vent piping,therefore, can not use ball floats as the only means of overfill protection. -On 12/28/2018, all three tanks failed the overfill prevention equipment inspection.The mechanical overfill prevention device in the diesel tank was set at 99%capacity and not at 95%or below as required.The 87 and 91 tanks did not have a mechanical means of overfill nor was there an audible/visual alarm to alert the fuel delivery truck driver when the tanks have reached above the 90%capacity. -On 11/12/2019, a repair permit(SR0080109)was approved to replace the 91 and diesel tank drop tubes but no work was conducted. -On 9/30/2020, a repair permit(SR0082633)was approved to replace the 87, 91 and diesel drop tubes and shut-off valves(flappers). During the 12/28/2021 service request inspection, the service technician onsite verified that the diesel tank did not have ball float installed but had an OPW drop tube with a shut-off valve.The 87 and 91 tanks had ball floats and straight drop tubes. Per technician,the 87 and 91 tanks passed and the flapper in the diesel tank failed. The service technician only took measurements of the tanks and did not perform the drop tube replacements. No tank charts were onsite for verification,when asked about tank charts the service technician stated that they were at the"shop."The repair permit was not conducted and Ghulam Ali (Operator)was notified indicating that the facility was not approved to receive fuel in the 87, 91, and diesel tanks. -On 1/8/2021, the diesel drop tube was replaced under repair permit number SR0082633.An OPW drop tube was installed in the diesel tank instead of the EMCO drop tube the permit was approved for. (An amended scope of work has not been submitted).The repair permit was not finalized at that time,flappers were not installed in the 87 and 91 tanks.The facility was not approved to receive fuel in the 87 and 91 tanks.A service request inspection was emailed to the Ghulam Ali (Operator)indicating the that the facility was not approved to receive fuel in the 87 and 91 tanks prior to EHD's approval due to the the replacement of drop tubes not being performed.As of today, 11/8/2021,the 87 and 91 tanks do not have an overfill prevention system REGULATION GUIDANCE:All underground storage tanks shall be equipped with an overfill prevention system that does not allow for manual override and meets one of the following requirements: 1. Alert the transfer operator when the tank is 90 percent full by restricting the flow into the tank or triggering an audible and visual alarm; or 2. Restrict delivery of flow to the tank at least 30 minutes before the tank overfills, provided the restriction occurs when the tank is filled to no more than 95 percent of capacity; and activate an audible alarm at least five minutes before the tank overfills; or 3. Provide positive shut-off of flow to the tank when the tank is filled to no more than 95 percent of capacity;or, 4. Provide positive shut-off of flow to the tank so that none of the fittings located on the top of the tank are exposed to product due to overfilling. CORRECTIVE ACTION: Immediately contact a properly licensed,trained, and certified contractor to install an approved overfill prevention system. Replacement of a mechanical flapper valve requires a permit and inspection by the EHD. If an external audio/visual alarm is replaced, provide a copy of the service receipt to the EHD. If an approved overfill prevention system can't be installed immediately,there is a possibility that the 87 and 91 UST system may be red tagged to prevent fuel inputs.
