<br />- Caution: Relieve all lank pressure prior to removing any fittings.
<br />No tank that shows any evidence of o leak Is to be kept in the system. Any

<br />responsibility. The Company Rep. is to be notified of any damage and will
<br />determine the course of action to be followed-
<br />.
<br />If a hydrostatic test is required by the local agency, isolate the tank for testing and
<br />reconrfect when testing is complete. The hydrostatic test will be obtained by
<br />Chevron.
<br />11, INTERNAL MEASUREMENTS: Tnke internal diameter measurements at the fill and the remote
<br />pump openings, on both single and double Boll FRP tonks. The Contractor, witnessed by the
<br />Company Rep., is responsible for making and recording these measurements on a form provided
<br />-
<br />by the Company. Take the first set of measurements prior to placing any backfill around the
<br />Conk. The second set of measurements is token when the backfill has reached subgrade (prior
<br />to pouring the concrete slob),
<br />If the difference between any 2 sets of readings Is greater than 1-1/4", stop the job.
<br />Notify the Company Rep., who will determine the course of action. Contact the tank
<br />manufacturer for further guidance.
<br />-12. BALLASTING: Only the primary (inner) tank shall be used when ballasting the took. Never fill
<br />the secondary (outer) tank with a fluid. If the tanks ore ballasted, conduct a Hydrostatic Test
<br />(instead of the post -installation oir test) on the tank and fittings.
<br />13. BURIAL DEPTH: The burial depth from the top of the lank to ground level shall be o minimum
<br />-
<br />of 3 feet and a maximum of 7 feet. The fittings, if a monway is used, will be approximately
<br />5
<br />5 - 6 Inches off the top of the lank. This shall be considered for the slope of the piping and
<br />thus may affect the tank burial depth.
<br />14, VENTING: Vent the annular space between the primary and secondary tank only if required by
<br />local jurisdictions. Venting of the annular space is not required by the tank manufacturer. If
<br />required, manifold a 2 inch FRP pipe between the tanks and connected to a separate vent riser.
<br />Do not use the primary (product) tank vent to vent the annular space,
<br />-
<br />15. INTERSTITIAL MONITOR: A pull string may be In the tank, install a new pull string H the
<br />-
<br />string is missing, lost, or broken. The pull string is not o tank manufacturer warranty Item.
<br />Install the 'interstitial monitor at the bottom centerline of the FRP tank. Insert fish tope
<br />through the annular space. Tog both the pull string and probe signal cable at 12.5 fl. plus the
<br />burial depth. Attach the pull string to the probe and to the fish tape and pull probe into tank,
<br />When the tags on the signal cable and the pull string match, the probe is at the bottom
<br />centerline of the tank. The pull string is to remain in place and future accessible.
<br />15. INSTALLING THE CONTAINMENT SUMP: The containment sump must be watertight to
<br />-
<br />prevent liquid ingress or egress. Install a gasket between the tank collar and the containment
<br />sump and make a tight seal with a petroleum resistant butyl caulking.
<br />Test the containment sump with water if required by local inspectors or Company Rep,
<br />17. INSTALLING THE SPILL CONTAINMENT FILLBOX: The spill containment fillbox must be '
<br />-
<br />liquid light. Test all fillboxes by filling with .water for a minimum of 1 hour. There should

<br />be no drop In the water level during this test. Do not drain water into the tank.

<br />05 TANK HOLD—DOWN INSTALLATION
<br />GENERAL REQUIREMENTS: Anchor oil underground storage tanks with concrete hold-downs
<br />("logs" or deadmen") when specified by Company Rep, in the Scope of Work. Refer to drawing
<br />F-9 (N -PET -1`9P-1).
<br />Tank bedding, ballasting and lank hole backfill procedures are described under Section 02 of these
<br />specifications.
<br />The tank anchorage system shown on the drawings is designed for o maximum level of ground water
<br />equal to the subgrade level,
<br />MATERIALS:
<br />1, CONCRETE HOLD-DOWNS: Pre -cast, reinforced concrete "logs', 12" x 12" or 12' x 24" in
<br />cross-section, with chomfered edges. Length, as shown on the drawings. 1/2" diameter
<br />galvanized steel anchor loops are to be cost into logs" at locations shown. Pre -cast material
<br />shall have achieved its ultimate compressive strength of 2500 psi (28 days) prior to installation.
<br />Pre -cast concrete foundation piles which meet or exceed above specifications ore acceptable.
<br />2. WIRE ROPE CABLE: Hot -dip galvanized steel wire rope, minimum 1/2" diameter, breaking
<br />strength, 20.4K.
<br />3. HARDWARE: Cable clamps, cable guides, guards, etc. shall be hot -dip golvinized steel.
<br />4. PROTECTIVE COATING:' Prior to backfilling tonks, apply a generous quantity of "Chevron
<br />Asphalt Coating" by brush to all exposed steel cables, loops and hardware.
<br />INSTALLATION PROCEDURE:.
<br />1. Prepare the tank hole to receive hold-down "logs'. Install shoring (or side sloping) in
<br />accordance with Section 02,
<br />2. Pump the water out of the tank hole. Keep water out of the tank hole until tanks have
<br />been set, tied down. bollosted and backfllied.
<br />3. Insert each Coble through its own ranchor loop in the "log" reserving sufficient cable so that
<br />both ends of the cable will be kept at the lop of the tank hole after the logs" are set.
<br />Lower and position the 'logs' in the tank hole keeping both ends of the cables at the top
<br />of the hole. Install the 2' miniimum thick bedding material in tank hole. Smooth and
<br />slope per the tank bedding instructions.
<br />4. Proceed with setting the tanks by adding ballast as necessary to sink and keep down the
<br />tanks. Use only enough ballast fol hold the looks down until the backfill is even with the
<br />top of the tanks. (Refer to Section 04 for tank setting requirements.)
<br />Caution: Ballast level in tank must never exceed water (or backfill) level in lank hole
<br />- during installation.
<br />5. Install the cable guards, guides, ell , on the designated ribs of the took.
<br />(Note: "Designated Ribs" are marked by arrows on the lank surface.)
<br />Caution: Do not place straps or cables between the ribs of the tank.
<br />6. Pass each set of cables (a set of cables is those cables passing throughthe matching, or
<br />opposite, loops on -the logs) through the guides and loops as shown on the drawing.
<br />One end of each cable is be crossed over the top of the tank in theretainer portion of the
<br />hold-down strap. Using three cable clomps on each set of cables, clamp both cables
<br />together on top of the tank. Prior to tightening the clamps, tension the cables with "come-
<br />. a -longs" secured outside the lank hole. Use enough tension to lighten the cables but not
<br />to lift the logs" or crush the tank.
<br />Caution: All sets of cables on a tank must be tightened equally .to avoid tank deformation.
<br />The cable must rest on the top of the hold-down strop between the guides provided.
<br />Repeat this process for each set of tie -down cables.
<br />After all tie -downs are completed, commence the backfill procedures to the top of the
<br />tanks.
