• TNC: Up to 30,000 gallons of fuel

• School: Up to 60,000 gallons of fuel

Answer: Response: All new 30,000 gallon tanks will be owner supplied.as noted in Specification Section 01 64 00.

3. Question: In spec section 33 56 13 1.2.4, I’m taking this to understand that the contractors are supplying and installing all appurtenances across all tanks, even if they’re furnished by owner?

Answer: The owner supplied tanks will not be equipped with any appurtenances except for ladders, catwalks, and appropriate plugs for shipping purposes. Contractor is responsible for furnishing and installing all tank appurtenances.

4. Question: The decommissioning schedule shown on sheet G1.4 appears to include incorrect volumes for the existing Corporation Horizontal Diked Tanks (tanks TD1 and TD2); please confirm.

Answer: Revise the volumes shown for existing tanks TD1 and TD2 to 30,000 gallons each.

5. Question: When is the expected date that the Owner supplied fuel tanks will arrive on site?

Answer: The owner provided tanks are being shipped via AML. Below is a message received from AML regarding the shipment into Tuluksak: “We’re tentatively estimating arrival into Bethel towards the end of the month (May) and will begin planning trips to

Tuluksak once operations are wrapped up. Historically we’ve arrived early to mid-June, however, we’ve been seeing lingering ice condition this season so please reach out for updates as we’re getting into early June, and we’ll help advise as we continue onwards”.

For bidding purposes, bidders may assume that the tanks will arrive in Tuluksak no later than July 31, 2026.

a. Question: If so, where is the preferred location?

Answer: The contractor will be responsible for all required temporary facilities necessary to provide uninterrupted fuel storage and retail dispensing services in the community throughout construction. Contact Agatha Fly above for information regarding potential temporary tank farm / retail dispensing facility location.

However, all coordination will need to be worked out between the contractor and the local tank farm owners.

b. Question: Can any of the tank farms be decommissioned prior to establishment of the new Co-Located Tank Farm?

Answer: The sequence for decommissioning existing tank farms will depend upon the amount of fuel present in each tank at the time of the project and coordination between the contractor and the individual tank owners. As long as local fuel storage and retail dispensing needs are met, the tank farm decommissioning can run independent of constructing the new co-located facility.

c. Question: What is the required amount of Fuel Storage needed through the winter, if temporary tank Farms are an option?

Answer: For the purposes of bidding, bidders may assume the following annual fuel consumption by user (Source: 2024 Conceptual Design Report).
