FJRP159073-M-003.DWG

1. TWO TANKS MUST BE OPERABLE AT ALL TIMES. AN EXISTING TANK CAN NOT BE REMOVED FROM SERVICE UNTIL THE NEW

TANK IS CONSTRUCTED AND COMMISSIONED. .

2. REQUIRED OUTAGES FOR MECHANICAL PIPING TIE-INS SHALL BE COORDINATED WITH THE BASE A MINIMUM OF 30 DAYS

PRIOR TO THE REQUIRED OUTAGE. OUTAGES SHALL BE LIMITED TO 3 DAYS INCLUDING THE WEEKEND, UNLESS

OTHERWISE COORDINATED WITH THE BASE.

3. TEMPORARY CROSSOVER CONNECTIONS BETWEEN THE NEW AND EXISTING PIPING MANIFOLDS MAY BE REQUIRED TO

ALLOW FOR CONTINUED OPERATION OF TWO TANKS.

4. MECHANICAL PHASING REQUIREMENTS SHALL BE COORDINATED WITH THE CIVIL PHASING REQUIREMENTS. THE

10” HYDRANT LOOP AND HHTC STAND PIPING SHALL BE CONSTRUCTED AND PHASED IN ACCORDANCE WITH THE CIVIL

PLANS.

5. SUGGESTED MECHANICAL PHASING SEQUENCE - TANK AND PUMP SHELTER. PHASING SEQUENCE MAY BE MODIFIED

PROVIDED OPERATING CONDITIONS ARE MET AND OUTAGES ARE LIMITED.

a. TYPE III PUMP SHELTER CONSTRUCTION.

b. TANK 3 CONSTRUCTION AND HYDROSTATIC TEST.

c. CONSTRUCT 6" STAINLESS STEEL UNDERGROUND PIPING FROM THE TYPE III PUMP SHELTER TO THE UNDERGROUIND

TRUCK OFFLOAD PIPING TIE-IN AND MAKE THE TIE-IN CONNECTION. TANK 1 AND 2 WILL REMAIN IN OPERATION AND

THE EXISTING ABOVEGROUND COMPONENT OF THE 6" TRUCK OFFLOAD PIPING/TANK FILL WILL REMAIN IN USE.

d. CONSTRUCT 8" FILL LINE FROM THE PUMP SHELTER'S SIX VALVE MANIFOLD TO NEW TANK 3. A TEMPORARY SPOOL TO

AVOID CONFLICT WITH THE EXISTING FILL AND SUCTION LINES WILL BE REQUIRED. PERMANENT FLANGES TO REMAIN

SHALL BE WELD NECK FLANGES. TEMPORARY FLANGES THAT WILL BE REMOVED UPON CONSTRUCTION COMPLETION

MAY BE SLIP ON TYPE OR WELD NECK TYPE.

e. CONSTRUCT 6"/12" SUCTION HEADER FROM NEW TANK 3 TO ABOVEGROUND SUCTION PIPING TIE IN LOCATION (6").

PROVIDE FLANGED CONNECTIONS TO ALLOW FOR THE INSTALLATION OF LATER PHASES OF SUCTION PIPING

INSTALLATION.

f. HYDROSTATICALLY PRESSURE TEST AND FLUSH NEW SECTIONS OF SUCTION AND FILL LINES. COMMISSION TANK 3.

g. TRANSFER FUEL FROM EXISTING TANK 2 USING THE EXISTING TRUCK FILLSTANDS AND REFULER TRUCK DEFUELING

CONNECTIONS. (MAX RATED FLOWRATE WITH BOTH PUMPS RUNNING 600 GPM, LIKELY LESS BASED ON PUMP HEAD

AVAILABLE). ALL REMAINING FUEL/WATER LOCATED IN THE BOTTOM OF THE TANK MAY BE REMOVED BY VAC TRUCK

USING THE EXISTING LOW SUCTION NOZZLE.

h. DEMOLISH EXISTING 6-INCH FILL AND SUCTION TO THE FURTHEST EXTENT ALLOWABLE TO LEAVE TANK 1 IN

OPERATION. PROVIDE FLANGE AND BLIND FLANGE OR WELD CAP ON EXISTING FILL AND SUCTION PIPING TO REMAIN .

i. MAKE ALL ALTERATIONS TO TANK 2 AND CONDUCT HYDROSTATIC TEST.

j. CONSTRUCT 8" FILL LINE FROM THE PUMP SHELTER'S SIX VALVE MANIFOLD TO EXISTING TANK 2.

k. CONTINUE CONSTRUCTION OF 12" SUCTION HEADER TO NEW SUCTION NOZZLE ON EXISTING TANK 2. PROVIDE

FLANGED CONNECTIONS TO ALLOW FOR THE INSTALLATION OF LATER PHASES OF SUCTION PIPING INSTALLATION.

l. HYDROSTATICALLY PRESSURE TEST AND FLUSH NEW SECTIONS OF SUCTION AND FILL LINES. COMMISSION TANK 2.

m.TRANSFER FUEL FROM EXISTING TANK 1 USING THE EXISTING TRUCK FILLSTANDS AND REFULER TRUCK

DEFUELING CONNECTIONS. ALL REMAINING FUEL/WATER LOCATED IN THE BOTTOM OF THE TANK MAY BE REMOVED

BY VAC TRUCK USING THE EXISTING LOW SUCTION NOZZLE.

n. DEMOLISH REMAINING EXISTING 6" FILL AND SUCTION PIPING FROM TANK 1 TO THE TIE-INS INDICATED IN BULLET 5c

AND 5e. PROVIDE WELD NECK FLANGE AND BLIND FLANGE ON THE SUCTION TIE-IN TEE (BULLET 5e). PROVIDE WELD

CAP ON THE TANK FILL TIE-IN TEE (BULLET 5c)

o. MAKE ALL ALTERATIONS TO TANK 1 AND CONDUCT HYDROSTATIC PRESSURE TEST.

p. CONTINUE CONSTRUCTION OF 12" SUCTION LINE FROM THE NEW SUCTION HEADER TO THE NEW NOZZLE ON

EXISTING TANK 2. CONTINUE 12" SUCTION PIPING FROM THE SUCTION HEADER TO THE PUMP SUCTION HEADER AT

THE PUMP SHELTER.

q. HYDROSTATICALLY PRESSURE TEST AND FLUSH NEW SECTIONS OF SUCTION, FILL AND ISSUE LINES. COMMISSION

TANK 1.

r. UPON COMPLETION OF THE HHTC STAND AND HYDRANT LOOP PIPING, HYDROSTATICALLY PRESSURE TEST AND

FLUSH NEW SECTIONS OF ISSUE AND RETURN LINES. COMPLETE FULL SYSTEM COMMISSIONING.
