AN ALTERNATE SUBMITTAL FOR THE UNDERGROUND FUEL OIL TANKS

AND PIPING IS BEING SUBMITTED FOR THE FOLLOWING REASONS

FROM OUR SUBCONTRACTORS GCH/RK/PLATT-ROGERS:

1. Due to the lengthy delay in procuring the tanks, there will be a price increase associated with purchasing the tanks from CSI; this price increase looks to be between 6 to 8%. In fairness to CSI, the final quote was from 12/23/13. The drawings were approved in May of 2014, and the pricing was still good then.

Most recently in 2015, we were suppose to set these tanks in June, then July, then August. I finally told CSI that we definitely needed a production spot for an October delivery. Now we are looking at mid January to early February.

2. When we give the green light to CSI to start production, we need to make sure that they can be delivered. CSI has already told us that we need to take possession of the tanks, and that they can’t sit in their yard. That said, we need to make sure that we are truly ready for the tanks.

3. The timing here is critical, but it does allow us the opportunity to consider the Xerxes tanks so that we can eliminate a cost increase.

Xerxes compared to CSI:

A. Xerxes has given us a quote that they will hold a price until February that will have no financial impact to the project.

B. When we give Xerxes the green light to start production, they can deliver in 6 to 8 weeks; almost 3 weeks faster than CSI.

C. Xerxes is a more flexible than CSI, if for some reason the schedule slips again (hopefully not), they are willing to hold the tanks at their facility for a reasonable duration of time (not to exceed 4 months.)

D. The Xerxes and CSI tanks are the same from a product standpoint. The VA will not be getting a better product, but it is not any less of a product.

E. Xerxes is an approved vendor for both the VA and USACE.

2. HANDLING AND STORING TANKS

2.1. GENERAL

2.1.1. Although our tanks are rugged, the tank owner and/

or tank owner’s representative must take care of the tank so that it is not dropped or damaged during loading, unloading, handling and storage at the jobsite.

2.1.2. Move tanks by lifting and setting only. Do not move

tanks by rolling or dragging.

2.1.3. Always lift tanks by using the lifting lugs provided

with the tank. Distribute the lifting load evenly between the lifting lugs. Use spreader bars and equal length slings as required.

NOTE: Larger tanks may be provided with guide lugs for attachment of guide ropes during lifting and positioning operations. Do not use guide lugs for lifting.

Never roll, drag or drop the tank. This could result in damage to the tank.

2.2. UNLOADING,HOISTING AND GUIDING TANKS

2.2.1. Before the tank is unloaded or relocated on the job-

site (and before preinstallation testing at the jobsite), tank owner and/or tank owner’s representative must complete the following steps:

2.2.1.1. Visually inspect the entire exterior surface of the

tank to make sure that no shipping or handling damage has occurred. Look particularly for visible damage, cracks or deep scrapes.

2.2.1.2. Sign the shipping papers accepting the tank as

delivered. Any damage observed must be noted in these papers.

2.2.1.3. Be sure that all equipment used to lift the tank is

rated to handle the load. Refer to Appendix A and/or B for weights.

2.2.1.4. Select a smooth, solid, level area on which to

place the tank, and clear that area of all large rocks, trash and debris.

2.2.1.5. Make sure that all tools and other items that may

damage the tank during unloading are removed from the trailer bed.

2.2.2. When unloading the tank from the truck, tank

owner and/or tank owner’s representative must make sure that the tank is secured in such a way that it does not roll off the truck.

Do not release straps securing the tank to the truck until lifting equipment (such as a crane) is secured to the tank’s lifting lug(s) and until anyone in a position to be injured by the tank’s movement is in a safe location.

Failure to do so could result in death, serious injury or property damage.

2.2.3. When hoisting and guiding the tank, follow these

instructions—see FIGURE 2-1, FIGURE 2-2 and FIGURE 2-3:

2.2.3.1. Choose suitable lifting sling(s) for the tank being

installed.

2.2.3.2. When using multiple lifting lugs, the angle of the

lifting sling should never exceed 30 degrees—see FIGURE 2-1.

FIGURE 2-1

2.2.3.3. When the tank is not rotated (the tank is upright), use all lifting lugs to unload and install the tank. See FIGURE 2-2.

2.2.3.4. Some tanks are rotated on the truck for shipping

purposes. These tanks have extra lifting lug(s) to aid in the loading/unloading process. See FIGURE 2-2.

2.2.3.4.1. Use the lifting lugs that are situated on top of

the tank in its rotated position to offload the tank from the truck and place it on the ground.

2.2.3.4.2. To install the tank, carefully rotate the tank to

its upright position and then use all lifting lugs situated on top of the tank in its upright position. See FIGURE 2-2.

FIGURE 2-2

2.2.4. Do not wrap chain or cable around the tank at any

time, including when securing the tank on the ground.

2.2.5. Use guide ropes to guide the tank when needed.

Do not use guide lugs for lifting. Failure to follow this warning could result in death, serious injury or property damage.

2.2.6. When handling a tank with a bottom sump or

fitting, always take extra care so that the bottom sump or fitting is not damaged by contact with any other object, such as the truck bed or the ground.

2.3. STORING TANKS

2.3.1. Whenever a tank is temporarily placed above the

ground at the site, place it on a smooth, solid, level area that is clear of large rocks, trash and debris, and then chock it in place to prevent rolling. See FIGURE 2-3.

Always chock the tank. The tank is heavy and has a large surface area. The tank will roll on sloped surfaces and could be blown about by the wind. Movement of the tank could result in death or serious injury.

2.3.2. Tie the tank down if high winds are expected. Do

not use wire rope or chains. Doing so could damage the tank. See FIGURE 2-3.

2.3.2.1. Never place tie-down straps over collars or reservoirs.

FIGURE 2-3

2.3.3. Whenever a tank is temporarily placed above the

ground at the site, always take extra care so water does not enter the collar. It is recommended that the tank be rotated and/or the collar covered.

If water enters the collar, it could freeze and could result in damage to the tank and/or collar.

3. PREINSTALLATION INSPECTION AND TESTING

3.1. GENERAL

Do not conduct preinstallation testing while the tank is on a trailer. Failure to follow this warning could result in death or serious injury.

Do not put product in the tank until all necessary preinstallation inspection and testing is completed.

Failure to follow this notice could result in property damage.

3.1.1. The applicable inspection and testing procedures set

forth in SECTIONS 3 and 4 must be performed to validate the applicable limited warranty.

3.1.2. All tanks are tested and inspected at the factory prior to shipment. However, in order to verify the absence of any damage resulting from shipping or handling, prior to installation all tanks must also be inspected at the site. Some tanks must also be tested at the site prior to installation according to the applicable procedures.

Always secure the tank before moving, rotating or lifting it. This is commonly done by connecting a crane or backhoe to the lifting lugs. Failure to follow this warning could result in death or serious injury.

While moving or lifting the tank, do not position any part of your body underneath the tank. Failure to follow this warning could result in death or serious injury.

Do not lift or hoist a tank under pressure. Failure to follow this warning could result in death or serious injury.

3.1.3. Not all tanks are air-testable in the field. If a tank needs to be hydrostatically tested, see SECTION 13.3.

3.1.4. If the tank is a water/wastewater tank equipped for

optional preinstallation testing, after inspecting the tank (see SECTION 3.2.), follow procedures in the Preinstallation Testing Instructions for Water/Wastewater Tanks Factory- Equipped for Pressure Testing supplement. See SECTION 20 for information on how to obtain this supplement.

3.1.5. If damage of any kind is detected, contact customer

service before installing the tank.

NOTE: Do not attempt unauthorized repairs.

3.2. INSPECTING THE TANK

3.2.1. Thoroughly inspect the entire outside surface of the

tank for signs of shipping or handling damage. Rotate or lift the tank to inspect the bottom of the tank.

3.2.2. If damage of any kind is detected, contact customer

service before installing the tank.

NOTE: Do not attempt unauthorized repairs.

3.3. PRETESTING PROCEDURES

Do not install any piping or fittings other than test fittings until all preinstallation testing has been completed. Fail-ure to follow this notice could result in property damage.

Never pressurize a wet interstitial space. Doing so could result in damage to the primary tank and/or tank failure.

3.3.1. All UL-labeled, ULC-labeled and potable water tanks

must be air tested after backfill is brought close to the top of the tank.

3.3.2. If the tank being installed is not an air-testable tank, proceed to SECTION 5.

3.3.3. See SECTIONS 3.4. through 3.9. for specific instructions for preinstallation testing procedures.

3.3.4. See SECTION 4 for preinstallation testing instructions for specific types of air-testable tanks.

3.3.5. Someone must be with the tank at all times during

air testing.

3.3.6. Prior to the pressure test, remove all plugs, apply

sealant, and replace and tighten plugs.

Before beginning the air test, notify all people on the test site to remain in a safe location. NEVER LEAVE A TANK UNDER PRESSURE UNATTENDED. Stand clear of manways, fittings and tank ends during the test. When the tank is under pressure, the manways, access open-ings and/or fittings may dislodge, or the tank could rupture, and this could result in death or serious injury.

3.4. PREPARING THE TANK FOR AIR TESTING

3.4.1. The air-test pressure is 5 psig [35 kPa] (3 psig [21 kPa] for 12-foot-diameter tanks). See FIGURE 3-1.

Do not overpressurize the tank. Position the pressure gauges so that the pressure readings can be clearly read at all times. The pressure gauge must have a pressure-relief valve that is used and set at 6 psig [40 kPa] (4 psig [28 kPa] for 12-foot-diameter tanks).

Failure to follow this warning could result in death or serious injury.

NOTICE

FIGURE 3-1

3.4.2. The tester is responsible for verifying that all of the test equipment is in good working condition, and is properly configured and calibrated.

3.4.3. Construct a test manifold with two pressure gauges as

shown in FIGURE 3-2. Each pressure gauge must have a max-imum full-scale reading of 15 psig [100 kPa] with graduations in 1/2 psig [2.5 kPa] increments, and a pressure-relief valve set at 6 psig [40 kPa] (4 psig for 12-foot-diameter tanks).

3.4.3.1. When air testing multicompartment tanks, a test

manifold is needed for each compartment. See FIGURE 3-2.

FIGURE 3-2

NOTE: All compartments on a double-wall tank may be manifolded together and tested simultaneously, or each compartment may be tested separately.

3.4.3.2. A test manifold is needed for testing the dry

interstitial space of an air-testable, double-wall tank. See

FIGURE 3-2.

NOTE: A test manifold is not required for a tank with an interstice filled with monitoring fluid.

3.4.4. During air tests, ambient air temperature can affect

pressure-gauge readings.

Allow for pressure variations when tanks are subject to abrupt temperature changes. Failure to follow this caution could result in minor or moderate injury.

3.4.5. When testing tanks with wet monitoring, remove

the reservoir-fitting plug.

3.4.6. If the tank has threaded fittings, it is the installer’s responsibility to select a thread sealant that is compatible with the product being stored. Some sealants cannot be used with some stored products.

3.4.7. Remove factory-supplied plastic temporary plugs

and install permanent plugs in all openings where piping will not be installed.

3.4.8. Make sure all manway bolts or flange bolts are tight-

ened to 25 ft.-lb. [34 N-m], and fitting plugs are properly doped and sealed.

3.4.8.1. The tank may be air tested with the factory-supplied temporary plugs. Redope and tighten temporary plugs if needed.

3.4.9. Keep one service fitting open in each compartment

for the test manifold.

3.4.10. Tanks equipped with flanged nozzles may require

contractor-supplied blind flanges for preinstallation air testing.

3.5. PRESSURIZING THE PRIMARY TANK

3.5.1. Install the test manifold in the open service fitting

and connect the pressure source to the test manifold. See

FIGURE 3-2.

3.5.2. If the interstitial space is dry, install the test manifold and close the valve before pressurizing the primary tank.

3.5.3. Open the air-supply valve and pressurize the primary

tank to 5 psig [35 kPa] (3 psig [21 kPa] for 12-foot-diameter tanks). Allow a few minutes for the air temperature in the tank to stabilize, then allow the pressure to stabilize by adding or removing air as necessary.

3.5.4. Hold and monitor the pressure for a minimum of 1 hour.

3.5.4.1. If the test manifold shows a pressure build-up in the interstitial space of a dry-monitor, double-wall tank, contact customer service.

NOTE: Do not attempt unauthorized repairs.

Maximum 5 psig

[35 kPa]

3.6. PRESSURIZING THE INTERSTITIAL SPACE IN A

DRY TANK

Never lift or hoist a tank under pressure. Failure to follow this warning could result in death or serious injury.

NOTE: Do not attempt unauthorized repairs.

3.6.1. Tanks with a dry interstitial space not shipped under vac-uum come with a quick-disconnect assembly. See FIGURE 3-3.

FIGURE 3-3

3.6.2. If the tank is not configured as shown in FIGURE 3-3

prior to installation, contact customer service.

3.6.3. The quick-disconnect assembly must not be connected

to the service fitting when air testing the primary tank. Keep the nylon tie in place.

3.6.4. Maintain the pressure in the primary tank.

Do not connect the air supply directly to the inter-stitial-space monitoring access fitting. Pressurizing the secondary tank (interstitial space) by itself could damage the primary tank or cause tank failure.

3.6.5. Free the hose from the service fitting by cutting the

nylon tie.

3.6.6. Insert the hose into the quick-disconnect fitting.

This will allow air to transfer from the primary tank to the interstitial space.

3.6.7. Reconnect the air-supply line. Allow the pressure

to stabilize at 5 psig [35 kPa] (3 psig [21 kPa] for 12-foot-diameter tanks) by adding or removing air as necessary.

3.6.8. Close the air-supply valve on the test manifold and

disconnect the air-supply line.

3.7. SOAPING THE TANK

3.7.1. After pressurizing the tank, soap the tank to check

the tank’s integrity.

3.7.1.1. Soap either the fittings, manways and covers or

the entire exterior of the tank, depending on what part of the testing process the tester is at and what kind of tank is being air tested. See SECTION 4 instructions for specific types of tanks.

3.7.1.2. Watch for active air bubbles. There should not be any.

NOTE: During freezing conditions, a suitable solution such as windshield washer fluid may be added to the soap and water mixture.

3.7.2. When doing a soap test, rotate the tank to check

the bottom. Do not rotate a tank filled with monitoring fluid.

3.7.2.1. Before rotating the tank, place protective material

on the area on which the tank will be rotated. Make sure the area is flat and free of large or sharp objects, such as rocks, which may damage the tank.

3.7.2.2. Rotate the tank slowly and carefully to avoid

developing too much momentum. Momentum can grow because manways and fittings on top of the tank make it top heavy. Make sure the tank’s fittings and manways never touch the ground. Do not rotate the tank more than 120 degrees from the initial starting point.

3.7.3. If damage is detected, contact customer service.

NOTE: Do not attempt unauthorized repairs.

3.8. PERFORMING VISUAL CHECKS ON A TANK

WITH A WET INTERSTITIAL SPACE

Never pressurize a wet interstitial space. Doing so could result in damage to the tank and/or tank failure.

Never rotate a tank filled with monitoring fluid. Doing so could result in damage to the tank and/or tank failure.

3.8.1. Check that the tank has monitoring fluid in the reservoir.

Measure the level of the monitoring fluid in the reservoir.

NOTE: If the reservoir is less than a third full, contact customer service. See the back cover of the Installation Manual for contact numbers.

3.8.2. Visually check the interior of the tank for monitoring fluid. There should not be any.

3.8.2.1. When checking a multicompartment tank, inspect

the interior of each compartment for monitoring fluid.

3.8.3. Visually check the exterior of the tank for monitoring fluid. (The monitoring fluid is dyed blue to distinguish between moisture and monitoring fluid.) If monitoring fluid is found, wipe the tank dry and verify that the monitoring fluid does not reappear. Lift the tank to check the bottom. Do not roll the tank.

NOTICE

3.8.3.1. When checking a multicompartment tank, inspect

the exterior of each compartment for monitoring fluid.

NOTE: Tanks are shipped with a pop-off valve to ensure that excess pressure does not build in the interstitial space during shipping and/or storage. Conditions such as excess heat can cause this valve to release. If the tank is rotated and the ambient temperature is much higher than when it was shipped, the pop-off value will relieve the pressure, which may result in monitoring fluid on the tank surface. If this occurs, wipe the tank dry and verify that the monitoring fluid does not reappear.

3.9. RELEASING PRESSURE FROM THE TANK

3.9.1. If there is an interstitial space to pressurize, open

the valve of the test manifold and carefully release the air pressure in the interstitial space first.

3.9.2. If the tank is a multicompartment tank, carefully

release the air pressure in the end compartments first.

3.9.3. Then carefully release the air pressure from the base tank.

Never allow the pressure in the interstitial space to be greater than the pressure in a primary tank. Fail-ure to follow this notice could result in damage to a primary tank and/or tank failure.

Never remove the service-fitting plugs when there is pressure in the tank. Failure to follow this warning could result in death or serious injury.

3.9.4. Remove the test manifolds and replace the protective

covers in the service fittings.
