Replacing Floor Plate - Remove Rust Scale?

Replacing Floor Plate - Remove Rust Scale?

(OP)
Hi. Working on a tank repair where we are replacing all floor plate due to soil side corrosion. Upon removal of old plate there is a layer of rust scale left behind which is quite brittle. Disturbing cause powdering and settling into aggregate foundation material. Question is: Will this rust scale be corrosion initiator to the new plate being installed if the scale is not removed?
