OAR 340-150-0352
UST System Modifications and Additions

(1)

An owner and permittee, or a licensed service provider on behalf of the owner and permittee, must:

(a)

Notify DEQ of their intent to modify an UST system at least 30 days before any modification work is scheduled to start by submitting an application for UST system modification to DEQ.

(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:

(a)

The lining is installed as specified by a code of practice developed by a nationally recognized association or an independent testing laboratory;

(b)

The modifications comply with all requirements of OAR 340-150-0360 (Requirements for Internally Lined USTs)(2) for internally lined tanks; and

(c)

A pressure-decay test, or other test, of the portion of the tank where the access way into the tank was installed, is performed before operating the tank after internal lining installation is complete.

(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. [Note: Publication is available from DEQ and the publisher.]

(5)

For modification of an UST system by the addition of new piping, an owner and permittee must comply with OAR 340-150-0160 (General Permit Requirements for Installing an UST System)(4), (5), (7), and (12).
(6) Metal piping and fittings that have released a regulated substance as a result of corrosion or other damage may not be repaired. They must be modified under OAR 340-150-0352 (UST System Modifications and Additions).

(7)

An owner and permittee may use the codes and standards listed in Appendix H of this division to comply with this rule. [View a PDF of Appendix H by clicking on the “Tables” link at the end of this rule.]

(8)

An owner and permittee must maintain records that demonstrate compliance with this rule for the remaining operating life of the UST system. Records must include a description of the work, date performed, name and address of the company that performed the work, equipment model number (as appropriate), test results, modification application and checklist and any other related data. An owner and permittee must make all records for UST system modifications and additions available for review by DEQ upon request.
