(b) Notify DEQ of the confirmed date and time the modification will begin at least three working days before beginning the modification to allow observation by DEQ.

(2) The owner or permittee must submit a completed UST system modification checklist to DEQ within 30 days after completing the modification.

(3) An owner and permittee of a metal UST previously protected with cathodic protection may modify the UST by the addition of internal lining if:

(4) An owner and permittee of a tank that has been internally lined may modify the tank by the addition of corrosion protection if the integrity of the tank is assessed using the method specified by American Petroleum Institute Publication 1631, "Interior Lining and Periodic Inspection of Underground Storage Tanks" to ensure that the tank is structurally sound and free of corrosion holes and that the lining is still performing according to manufacturer requirements.
