SKS E. Street Tank Removal
Jauregui & Culver, Inc. removed three 10,000 gallon double wall tanks from the site. We provided UST removal permits from the San Diego County DEH and city Fire department. Temporary facilities and storm water control measures were provided as needed, including fencing, sanitary facilities, and storm water inlet protection. The fuel system was removed, including the tanks, product piping, vapor return piping, and vent piping. We removed and disposed the hardscape over the tanks and piping. All concrete fuel islands, and all equipment on them including the dispensers, lights, pedestals, bollards and UDC’s, generator shed, and electronics cabinet were also removed. We washed, iced, hauled, and lawfully disposed of the USTs, including waste manifests of UST wash materials and tank destruction receipts. After removal of the tanks and piping, we back-filled and compacted the tank excavation and trenches with materials taken from them during the removal process. New backfill material equal in volume to the removed UST’s were included.
Sam’s Club Murrieta #4822
Jauregui & Culver, Inc. provided a turnkey fuel system replacement including tanks, dispensers, piping, monitoring system, Healy Clean Air Separator, and vent assembly. Additionally, we furnished and installed a 10,000 gallon diesel UST to add to the existing fuel system.
Hoehn Mercedes Upgrade
Jauregui & Culver, Inc. furnished and installed new double wall fiberglass underground piping, fiberglass sumps for the existing tank collar, dispensers and pump containment boxes, and all penetration fittings. All existing product dispenser containment box and tank sumps were removed per DEH requirements and soil samples were analyzed. The existing underground tank, tank collars, and vent lines remained in place.
Jauregui & Culver, Inc. will continue to provide monitoring certification, precision line testing, and SB989 testing to insure the safety and functionality of the site.
Dion & Sons AST Removal & Replacement
Jauregui & Culver, Inc. removed the three existing diesel above ground storage tanks (ASTs) located at the existing Woodside facility and replaced them with two 12,000 gallon cylindrical ASTs.
Jauregui & Culver, Inc. provided necessary drawings and submittals to the City in order to procure permits. The removal of existing tanks included the removal of the sheet metal roof, sheet metal wall and support framework, and chain-link gates. The existing ASTs were washed and lawfully disposed of. The existing AST masonry support structures, tank slab, curbing, and concrete drive slab were removed so that the new ASTs could be placed side by side with adequate setback distances between the building and the ASTs. The existing diesel below ground piping extending from the pump to the AST enclosure was cut and temporarily capped while Jauregui & Culver, Inc. installed a new SWFG piping transition sump and extended the piping. Jauregui & Culver, Inc. poured a new slab. We furnished and installed 6″ diameter concrete filled steel bollards. The ASTs were assembled and installed.
Jauregui & Culver, Inc. will continue to do the testing and maintenance of this facility, ensuring that it is safe, up to code, and working properly for Dion & Sons.
Fuel Polishing
When the mass power outage spread through Southern California and parts of Arizona in 2013, those who had generators and other forms of emergency power were ahead of the curve. They were prepared, but was their fuel? If your diesel fuel has been stored or unused for a long period of time, then it is of utmost importance to have it polished.
A clean fuel system is essential for preventative maintenance for your diesel engine. One of the main problems with diesel fuel is contamination from algae, microorganisms, fungus, yeast, and bacteria. Algae survive on the hydrocarbons in the fuel and the oxygen in the water in suspension and in the bottom water. If left untreated, the contamination can cause plugged filters, motor operation problems, and expensive repairs. These preventable symptoms of unclean fuel can and will lead to unnecessary failure of your emergency generator.
Early signs of contamination include but are not limited to:
- Dark, smoky exhaust that persists even after the engine of your generator has warmed up.
- Any discovery of corrosion in the fuel tank, or other metal parts that contact the fuel
- Hard deposits on engine injectors are an early and often subtle indicator. (Normal deposits should wipe clean with a cloth.)
The process is relatively simple. We circulate the fuel through a special filter system which removes particulates and purifies the fuel. We then place an additive into the fuel which kills any remaining algae and aids in keeping the fuel clean. There is a clear distinction between samples taken before and after polishing. Upon request, samples can be analyzed through a lab to provide further verification of these results.
At Jauregui & Culver, Inc., we want to serve you and help prevent the expense and inconvenience of generator failure as a consequence of contaminated fuel. It is recommended that your fuel be polished at least once every two years, though most major oil companies, engine manufacturers, and regulatory bodies recommend polishing yearly for back up power sources. In critical facilities, such as hospitals, fuel should be polished at least twice annually to ensure that it is in pristine condition when it is needed for use.
We’ll clean up your fuel and keep you out of the dark!

COC Fuel Facility
Jauregui & Culver, Inc. did a full design build for the County of San Diego Operation’s fuel facility. We procured permits, installed tanks, canopy, and a fuel system. We custom built the shoring that went in on the sides of the tank hole. The concrete footings, tank slab, and drive slabs were poured. Jauregui & Culver, Inc. also installed the fuel management system and continues to provide service and testing for the station. The existing fuel site was demolished, and can be seen here.
In addition, Jauregui & Culver, Inc. provided piping for the emergency generator system and is continuing to design build for the emergency generator system and other projects at this facility.
Sam’s Club Bakersfield #4819
Sam’s Club #4819 Bakersfield was a ground up fuel station. Jauregui & Culver, inc. excavated and installed two 20,000 gallon 87 gasoline and one 20,000 gallon split 12,000/8,000 10′ diameter Xerxes Underground Storage Tanks (UST) and deadmen.
We installed Fiberglass, APT, and steel piping to compile the fueling system, including trenching and gravel backfill. Two 3+1 gas/diesel dispensers and four 3+0 gas dispensers were installed, including the Under Dispenser Containment (UDC) basins, dispenser hanging hardware, and dispenser valance. Brine and vacuum tubing for the Veeder Root continuous monitoring and Pressure and Flow sensors in dispenser for the In Station Diagnostics (ISD). The Healy Clean Air Separator (CAS) was installed as part of the EVR II system.
We provided required Enhanced Leak Detection (ELD) testing of the fuel system at the conclusion of the installation of the fueling system and prior to opening. All fuel lines were purged and the dispensers calibrated, completing this project.
LPL San Diego Tower
Jauregui & Culver, Inc. procured permits for and installed a 4,000 gallon Above-ground Storage Tank (AST) for diesel and double wall steel fuel piping. We furnished and installed AST remote fill assembly, fuel filtration unit, fuel management control panel, Duplex pump system, and tank monitoring system, including all low voltage electrical wiring and conduit.
Pala Mini Mart Dispenser Replacement
Jauregui & Culver, Inc. furnished and installed new dispensers for the Pala Casino Mini Mart. We also fabricated and installed a column style canopy extension which including engineer drawings and structural calculations.
Pala Mini Mart Re-Pipe
Jauregui & Culver, Inc. replaced the fuel piping for the Pala Mini-Mart. We phased the work so that at least one row of dispensers was operational during construction. We purged the fuel in the existing below ground piping back into the underground storage tanks (USTs) with pressurized nitrogen. The existing piping was abandoned in place after the fuel was removed.
We sawcut and removed the existing concrete and asphalt surfaces between the USTs and the dispensers as needed for the installation of the double wall fiber glass piping. We dug pipe trenches and gravel bedding materials required by the pipe manufacturer and to meet industry standards.
We performed pressure tests to all the new piping per industry standards. We purged the fuel into the new piping system and tested for proper operation, calibrated the dispensers, and replaced all dispenser fuel filters.
