Several items listed in these specifications may be deviations from your standard tanks and therefore careful review of these specifications and close contact with the CO are very important. Provide ports for filling, suction, fuel quantity gauge, interstitial leak detection, , one for normal venting of the primary tank, two for emergency venting of the primary and secondary tank and one spare port for the primary tank plugged with an approved cast iron plug and a frost proof drain valve.

Appurtenances:

1. Marine grade coating system, gray color

2. One (1) each normal vent pipe long enough to be twelve (12) feet above ground level.

3. One (1) each normal vacuum pressure vent set below the pressure of the emergency vents

4. Two (2) each emergency vent pipes long enough to be two feet above the top of the tank

5. Two (2) each emergency vacuum pressure vents for the emergency vents.

6. One (1) each overfill containment basin with a flow back drain

7. One (1) each OSHA approved end mounted ladder

8. One (1) each anti siphon valve sized for this tank system

9. One (1) each interstitial leak detection indicator

10. One (1) each clock type battery powered alarming fuel quantity gauge

11. Fill and suction tubes

12. System shall arrive as completely assembled and as ready for use as possible.

2. All services and labor to remove and dispose of the existing 500 gallon dw heating oil tank system. Provide a work plan as to how this will be accomplished complete with cost proposal. The existing tank system will have approximately 20-25 gallons of fuel in it.

3. All services and labor to install the new heating oil tank system in the designated place at 1412 Airport Way, Fairbanks, Alaska 99701 and connect this system to the building heating system. Run an operational test and provide the government with manufacturers instructions. Provide a work plan as to how this will be accomplished, complete with cost proposal.

DELIVERY REQUIREMENTS: The delivery site is The availability of equipment in interior Alaska and surrounding remote areas is unknown. The government has no equipment or resources to transport or deliver the tank system and no government furnished equipment is part of this contract. The Contractor has full responsibility for the tank until it is delivered FOB to the site.
