The following is an itemized list of aboveground petroleum storage act violations that have not been addressed for Gemco Ripon Truck Plaza Inc. as of September 29, 2021. Open violations from February 10, 2020 inspection Violation#706-Failed to provide and maintain adequate secondary containment. The secondary containment for the 20,000 gallon tanks appeared to not be sufficiently impervious to contain discharged oil.The western end of the containment berm appeared to have a circular depression which had a hole approximately one inch in diameter on the floor of the diked area.The hole seemed to have mud in it. Facility personnel were unsure what this was for or whether or not this hole was used for drainage. Material around the hole seemed to suggest liquid pooled around it, but what happened to the liquid is unclear.This hole is not addressed in the SPCC plan. This may traverse the concrete bottom and it may be a way for liquid to escape the secondary containment.A pipe that seem to go underground,within the containment dike of the 20,000 gallon tanks was observed on the western half of the diked area. Facility personnel could not identify where the pipe terminated of what it was for.The pipe went underground by the pumps that pump the diesel from the tanks to the dispensers. The other end of the pipe was observed near the loading area of the tanks.The pipe appeared to have an open end which would allow any liquid release to travel through it.The pipe was between 1 to 2 feet above the ground level, significantly lower than the top of the dike wall. This pipe was not discussed in the SPCC plan and could potentially make the secondary containment sufficiently impervious to contain discharged oil.Two other pipes at ground level were observed near the loading area of the 20,000 diesel tanks. These pipes were within the containment dike, near ground level.The end of the pipes could not be determined by facility personnel. One of the pipes had a completely open top and the other had what may have been a cover, but did not appear to be liquid tight.These two pipes may potentially make the secondary containment sufficiently impervious to contain discharged oil and are not addressed in the SPCC plan. Parts of the SPCC plan describe the 20,000 gallon tanks as double walled,other parts of the SPCC plan describe the tanks as single walled. Per facility manager and observations,the tanks appear to be single walled tanks. The 20,000 gallons tanks may be permanently manifolded tanks. Four 20,000 gallon tanks were observed and appear to share common piping and only one pipe travels from the tank farm to the dispensers. The SPCC plan may need to have a discussion on whether or not the tanks meet the definition of permanently manifolded tanks and if so, how secondary containment is achieved. Construct all bulk storage tank installations(except mobile refuelers and other non-transportation-related tank trucks)so that you provide a secondary means of containment for the entire capacity of the largest single container and sufficient freeboard to contain precipitation.You must ensure that diked areas are sufficiently impervious to contain discharged oil. Dikes, containment curbs, and pits are commonly employed for this purpose.You may also use an alternative system consisting of a drainage trench enclosure that must be arranged so that any discharge will terminate and be safely confined in a facility catchment basin or holding pond. Ensure that diked areas are sufficiently impervious to contain discharged oil and that secondary containment is provided for the entire capacity of the largest single container and sufficient freeboard to contain precipitation, including the combined capacity of tanks which are deemed to be permanently manifolded. .This may have to be certified by a Professional Engineer through the SPCC plan. Note: Permanently manifolded tanks are tanks that are designed, installed,or operated in such a manner that the multiple containers function as a single storage unit(67 FR 47122, July 17,2002).Accordingly,the total capacity of manifolded containers is the design capacity standard for the sized secondary containment provisions(plus freeboard in certain cases). ❑ This violation was corrected ❑This violation will be corrected by(date): ❑ Supporting documents included Describe actions taken or will be taken to correct violation: Page 8 of 11
