1 SECTION FUEL PIPING SYSTEM AND FUEL TANK RELOCATION PART 1 GENERAL 1.01 SCOPE OF WORK A. The work of this section includes all labor, materials and equipment required for the installation and testing of the fuel piping systems as required to be completely ready for operation. The system will include a relocated aboveground 2000 gallon diesel fuel storage tank, new fuel piping system to an existing relocated emergency generator, relocated stairs and relocated Greenleaf solar gauge monitoring system, and all required accessories. B. The work of this section shall include picking up the existing tank from the West Nassau Water Treatment Plant located at Robert E. Williams Drive, Yulee, Florida, transporting and re-installing the tank, furnishing and installing new fuel piping system, relocating and reconnecting the fuel storage tank monitoring system, and all required accessories at the Otter Run Water Treatment Plant located at Otter Run Drive, Fernandina Beach, FL C. The work of this section shall include furnishing and installing the fuel piping system and all required accessories. D. Contractor shall furnish and install concrete pads as required by the structural drawings and FP drawings, fuel piping and fuel tank accessories. Contractor shall provide all fuel for the required generator testing in specification section and then filling the tank after all testing to 90% capacity (1,800 gallons) prior to substantial completion. E. The CONTRACTOR shall perform the following tasks associated with the relocation of the fuel tank: a. Draining, vacuuming and clean tank prior to moving. Do not handle or move the tank unless it is empty. b. Pressure testing prior to moving. c. Shipping and offloading of tank with lifting straps, nylon tie-down traps, crane, forklift, and carpet remnants strategically placed on the bevels to

2 prevent the tie-down straps from scraping the paint loose while the tank is in route. d. The tank is to be relocated using the Department of Transportation (DOT) Guidelines for transportation of fuel containers. Department of Transportation prohibits transportation of tanks with product and warning labels. Product and warning labels shall be installed on site. If installed at the plant, they should be masked prior to shipment. Labels and decals must be place on the tank in accordance with NFPA 709. e. CONTRACTOR to perform the following cleaning guidelines and shall contact the Authorities Having Jurisdiction (AHJ) to confirm if any additional procedures are to be performed prior to moving: i. Remove all liquids from the tank ii. Clean and rinse tank three (3) times with an approved cleaning agent iii. Allow sufficient time for vapors to escape from the tank. iv. Move the tank under the supervision of the AHJ. f. Pressure test tank after installation. CONTRACTOR shall obtain the required state and local permits and shall submit to the Engineer all testing reports upon completion. g. A vacuum pump is required to perform the following integrity test for fuel tank. Remove all appurtenances on the secondary tank and cap all openings with steel plugs or caps. These items must be free of leaks and should be tested by pressuring the secondary tank to one (1) pound of pressure and performing a soap suds tests. h. Use the necessary fittings required to connect a vacuum pump and a vacuum gauge to the leak sensor fitting in the secondary tank. Once all fittings have been sealed, start the pump and pull a vacuum up to 6 inches of mercury. Since there may be insulating concrete in the interstitial space, it will take longer to achieve a vacuum due to the porous nature of the lightweight concrete. After a vacuum of 6 inches have been achieved close the ball valve, shut down the pump and maintain the vacuum for a period of 12 hours. If vacuum is maintained (plus or minus 2 inches of mercury), both tanks are free from leaks. i.
