653 repairs
(OP)
Regarding 653 related repairs to large EFR tanks with cement floor cover I am considering liners as an alternative to slotting the shell and installing a new floor. After doing a couple of slotting jobs I would prefer to leave the shell undisturbed. Since I cannot establish a corrosion rate without removing the cement or gunnite where do I stand in terms of compliance with the 653 regs?
Any further advice or experience appreciated.

Since we cannot establish corr. rate under the cement, how is the next insp. due date established?
