NFPA 31 - 7.12 Abandonment and Removal from Service of Tanks and Related Equipment states "...if a tank and it's related piping are abandoned for whatever reason...". My issue is with the word "and".
A customer had a new fill and vent installed on an inside oil tank but left the old fill and vent piping in place, not connected to the tank.
The wording here, technically, could be construed to mean this is acceptable as the tank was not abandoned. Am I reading this wrong? Is there a standard that states that piping not in use/abandoned must be removed?
