Indicates a potentially hazardous situation, which if not avoided may result in property damage.

• These instructions provide the minimum requirements for the successful installation of a fiberglass underground storage tank under normal conditions.

Containment Solutions does not design or engineer the actual installation. The owner’s Engineer of Record for the installation can exceed these minimum requirements and is responsible for the final design.

• The presence of any Containment Solutions representative at the job site does not relieve the contractor of responsibility to follow these installation instructions.

TANK WARRANTY ACTIVATION

• These instructions must be followed.

• The Tank Installation Checklist (Pub. No. INST 6002) must be properly completed and signed by the tank owner’s representative and the installing contractor.

• The Tank Installation Checklist, these instructions and any correspondence related to the tank installation must be retained by the tank owner and provided to CSI to validate any future warranty claim.

• The warranty in effect at the time of tank delivery will apply and is available from Containment Solutions.

BEFORE YOU BEGIN

• Read, understand and follow these instructions.

• Barricade the tank area until the job is completed.

• Review and prepare to complete the installation checklist.

• Check with local authorities for building codes, underground utilities and testing requirements.

• If you have installation questions or need alternate installation methods, contact CSI Tank Technical Support.

• If you have other questions regarding tank modifications, such as adding fittings or manways or tank repair, contact Containment Solutions Field Service.

• A list of supplemental documents is found in Section R.

ASPHYXIATION FIRE EXPLOSION

Do not enter tank or sumps unless following OSHA guidelines for confined space entry. Failure to follow OSHA guidelines could result in death or serious injury.

Do not stand on or under tank while tank is being lifted. This could result in personal injury or death.

- Chock with sandbags.

- If high winds are anticipated, tie the tanks down to prevent damage.

- When the tank must be rolled for air/soap test, roll only on shipping pads or smooth surface free of protruding rocks or hard objects. Ensure fittings and/ or collars do not come in contact with the ground.

- Protect collars from water accumulation in freezing conditions or tank damage may occur.

To avoid tank damage:

• Do not allow tank to rotate or swing during off loading.

• Do not use chains or cables around tanks.

• Do not allow metal hardware to contact the tank.

• Do not allow fittings, collars, manways, reservoirs, or any accessory to contact ground during rotation.

• Do not drop tank.

LIFTING TANKS

To lift the tank, always use the number of lift lugs indicated on the label adjacent to the lift lugs. Slings may also be used to lift the tank. Refer to Supplemental Documents (Section R) for additional information. Apply equal tension to all lift lugs simultaneously.

Identify the tank lift lug orientation and use the appropriate method to lift the tank. The tank orientations are shown below.

Handling & Preparation

• The contractor is responsible for rigging, unloading and securing the tank.

• Tanks must be mechanically unloaded under the direction of a qualified rigger.

• Upon tank delivery and when lifting tank, visually inspect entire exterior surface of the tank for shipping or handling damage. If the tank has a wet annular space, inspect for monitoring fluid on the exterior surface.

• Before unloading a tank from the truck, the contractor must make sure all tools, hardware, supplies and anything else capable of damaging the tank are removed from the trailer bed.

• The contractor is responsible for making sure the tank is secure before removing shipping straps so the tank does not roll off the truck or trailer.

• For tanks with a bottom sump or bottom fittings, be sure the bottom sump or fittings are not damaged by contact with any object. Refer to Supplemental Documents (Section R) for additional information.

• For temporary storage of tanks at job site:

- Set on smooth ground (no protruding rocks or hard objects) or on the shipping pads oriented to allow for tank rotation as needed.

LIFTING CSI DEADMEN

• Insure lifting equipment is rated to handle the load before lifting. For deadmen sizes and weights use Table A-5.

• Lift deadman using a minimum of two equally spaced anchor points.

• The angle from the deadmen to the lifting equipment should always be between 60º and 90º (see Figure A-4).

• The deadmen type, lengths, and the number of anchor points are dependent upon the tank diameter, model and capacity.

• Refer to Supplemental Documents (Section R) for additional information on deadmen anchors.

LIFTING TANK SUMPS OR RISERS

• Visually inspect the sump components for shipping damage. If damage is found, contact CSI Field Service.

• Wear gloves.

• Do not roll, drop or bounce.

• Set on smooth surface.

• The sump must be secured to prevent damage from high winds.

• Refer to Supplemental Documents (Section R) for additional information on tank sumps.

C. PRE-INSTALLATION TESTING

The following instructions apply to all air tests described in Sections D1 to D9. Some Non Petroleum tanks are not field air-testable and require a post installation water test (Section D10).

VISUAL AIR/SOAP TEST

To be performed on all tanks after unloading from the truck.

• Single-Wall and Dry Annular Space Tanks: air/soap tests must be performed at the job site prior to installation to verify the absence of damage.

(Sections D1 to D6)

- For tanks shipped with annular space under vacuum, refer to Supplemental Documents - Section R.

• Liquid Filled Annular Space Tanks: air/soap tests on accessories and fittings can be performed after the tank is in the excavation. (Sections D7 to D9)

• All tanks must be vented at all times except as defined during testing.

FOR ALL AIR TESTS:

• All petroleum tanks with a UL label and all potable water tanks must be air tested prior to installation.

• Use a contractor supplied “Tank Test Manifold” connected to a tank primary fitting (see Figure C-1).

For tanks with any dry annular space configurations, including double-wall bulkheads:

• Use a contractor supplied “Annular Space Gauge and Valve” connected to the annular space fitting (see Figure C-2).

Do not pressurize 4', 6', 8' and 10' diameter tanks over 5 psig (35 kPa). Do not pressurize 12' diameter tanks over 3 psig (21 kPa). Tank damage or physical injury may result.

Pre-Installation Testing C

• Prepare for testing.

- Replace all fitting plugs with plugs suitable for the product to be stored in the tank.

- Clean factory pipe dope from plugs and fittings.

- Apply pipe dope suitable for the material being stored in the tank.

- Reinstall and tighten fitting plugs.

- Assemble the required number of “Tank Test

Manifolds” (Figure C-1) and “Annular Space Gauge and Valves” (Figure C-2).

- Gauges must have a maximum full-scale reading of 15 psig (40 kPa) with ¼ psig (1 kPa) or smaller increments.

- Pressure-relief device must be sized and set to prevent the tank from being pressurized in excess of the maximum allowed test pressure (5 psig / 35 kPa maximum or 3 psig / 21 kPa for 12' tanks).

• Do not pressurize 4', 6', 8' and 10' diameter tanks over 5 psig (35 kPa). Do not pressurize 12' diameter tanks over 3 psig (21 kPa).

• Pressure gauge readings can be affected by changes in ambient air temperature. Allow for pressure fluctuations when tanks are subject to temperature changes.

• Prepare Soap Solution.

- Warm weather soap solution

• 5 gallons of water

• 8 ounces of household dishwashing detergent

- Freezing conditions soap solution

• 4 gallons of water

• 8 ounces household dishwashing detergent

• 1 gallon windshield washer solution

• The entire tank surface must be covered with the soap solution and visually inspected for leaks, as indicated by the presence of active air bubbles.

• Anytime bubbles are observed around fittings, plugs, and gaskets; tighten and retest.

• In the unlikely event a tank leak is discovered, discontinue the installation and immediately call CSI Field Service to schedule a repair.

• If the tank is a Non Petroleum tank and requires post installation water testing, follow the procedures in Section D10.

Do not connect the air supply directly to the annular space monitoring fitting or tank damage will result.

Do not stand on or approach endcaps, manways, or fittings while pressurizing tanks. Do not lift or hoist tank under pressure. These actions could result in death or serious injury.

A NON AIR-TESTABLE TANK

(NON PETROLEUM TANKS)

These instructions are for tanks that require a post installation water test.

Perform the following in the order listed.

1. Comply with the requirements of Section C.

2. Tanks may only be water tested if the backfill is at tank top (see Figure D10-1).

3. Expose tank penetrations on tank top by temporarily removing backfill.

4. So water does not exit the inlet/outlet pipe, install a turned up elbow or plug.

5. Completely fill the tank with water to a level 2" into the access collar(s).

If the tank is to be water tested, it must be supported by backfill on all sides to the top of the tank. Failure to do so may result in tank damage.

E. EXCAVATION AND TANK CLEARANCE

STABLE EXCAVATIONS

• When your excavation is in stable, undisturbed soil;

use the minimum spacings (per Figure E-1 and Table E-2).

16. With all compartments under pressure, cover fittings and manway(s) with soap solution and inspect.

17. After completing air test, release pressure.

18. Remove all gauges, valves, and hose assemblies.

TABLE E-2

SHORING REMOVAL

• After the backfill is properly placed completely around the tank(s):

- Vibrate shoring and pull slowly to top of backfill.

- Fill any voids created by the pulled shoring with approved backfill.

• All shoring should be removed and all voids must filled using a long handled probe before continuing installation.

• If shoring is left in place, the shoring must not degrade over the life of the installation.

TANK LOCATION - NEARBY STRUCTURES

• The tank owner or the tank owner’s representative is responsible for determining the proper location of a tank excavation.

• The location of a tank can be affected by the location of nearby structures. When selecting a tank site, care must be taken to avoid undermining the foundations of new or existing structures.

• Ensure that downward forces from loads carried by the foundations and supports of nearby structures (constructed before or after tank installation) are not transmitted to the tanks. (Refer to NFPA 30 for additional details).

UNSTABLE EXCAVATIONS

• An unstable excavation is any of the following:

- Muck, bog, peat, swamp, quick sand, flowing water, landfill type areas or any other situations where the soil is inherently unstable.

- Soil less than 750 lbs./sq. ft. cohesion per ASTM D2166 (Test Method for Unconfined Compressive Strength of Cohesive Soil), or have an ultimate bearing capacity less than 3,500 lbs./sq. ft.

• A soils consultant can provide additional recommendations, including when a reinforced pad is needed under the tank.

• When a bottom pad is used, it should extend to the excavation walls.

• Unstable excavations may also require geotextile fabric (see Section F).

• When the soil is unstable, with or without shoring, use the minimum spacings (per Figure E-3 and Table E-4).

F. GEOTEXTILE FABRIC

Geotextile fabric (filter fabric) allows the passage of water but prevents the migration of approved backfill into the native soil and native soil into the approved backfill.

Migration may compromise the backfill support of the tank.

GEOTEXTILE FABRICS ARE REQUIRED FOR ANY

OF THE FOLLOWING INSTALLATIONS

• Areas subject to tidal conditions.

• Areas subject to frequently changing ground water levels.

• Water conditions with silty soil.

• Muck, bog, peat, swamp, landfill type areas or any other situations where the soil is inherently unstable.

• Soils with less than 250 lbs./sq. ft cohesion or with ultimate bearing capacity of less than 500 lbs./sq. ft.

• Geotextile fabrics may also be used in alternate installation methods (see Supplemental Documents, Section R).

The tank owner or tank owner’s representative may also specify the use of geotextile fabrics.

Non-degradable geotextile fabric can be either woven or non-woven and should have a minimum grab tensile strength of 120lbs/inch (ASTM D4595) and a maximum apparent opening size of #50 US sieve (0.300mm)

(ASTM D4751).

Do not use plastic, or any other material that may tear or degrade over time, as a replacement for geotextile fabric.
