0004 1 Job:

- STI Internal Tank Inspect FAC 870 FFP All work to conduct Kick-Off Meeting, complete STI Internal tank inspection, fuel removal/transfer, tank cleaning, UT scanning, complete visual inspection of containment, and complete DRAFT and FINAL reports

Can we have access to supporting documentation/drawings for Tank 870.

Also Attachment B states the manway is 36" and has only 1, confirm this drawing matches the tank on site?

Data in the previous 653 report states" Shell Manholes OBSERVATION: The tank is equipped with one 24-inch and one 30-inch manhole which is less than the current requirement for two 36-inch manholes.

How many manways need to be secured with new gaskets and bolts?

What are the correct sizes?

What is the bolt diameter of the manways?

What size bolts are requested?

The 30" manway has the following characteristics:

The 20" manway has the following characteristics:
