OAR 340-150-0320
Corrosion Protection Performance Standards for USTs and Piping

(1)

An owner and permittee must protect all USTs, whether of single wall or multiwall construction, and underground piping that routinely contains a regulated substance from corrosion by one of the methods listed in sections (2) through (4) of this rule.

(2)

For USTs and underground piping clad or jacketed with a non-corrodible material or other nonmetallic materials, an owner and permittee must use one of the codes and standards listed in Appendices D1-USTs and D2-Piping of this division to comply with this section of the rule. [Note: View a PDF of the appendices by clicking on the “Tables” link at the end of this rule.]

(3)

An owner and permittee must provide cathodic protection for USTs and underground piping constructed of steel or other metal to prevent corrosion by using the codes and standards listed in Appendices E1-USTs and E2-Piping of this division to comply with this section of the rule. [Note: View a PDF of the appendices by clicking on the “Tables” link at the end of this rule.]

(4)

In addition, an owner and permittee must comply with subsections (a) through (c) and either (d) or (e) of this section:

(a)

The UST and underground piping must be coated with a suitable dielectric material;

(b)

Field-installed cathodic protection systems must be designed by a corrosion expert;

(c)

Impressed current systems must be designed to allow the testing of current operating status as required by OAR 340-150-0325 (Operation and Maintenance of Corrosion Protection)(3); and

(d)

A permanent cathodic protection test station must be installed. The test station:

(A)

Can be separate or combined with an existing box and must be located near the protected structure (e.g., UST, piping, etc.) and away from an anode;

(B)

Must provide, at a minimum, an electrical connection to the structure and access for placing a reference cell in contact with the soil or backfill; and

(C)

When located below the surface of the ground, the test station design must prevent run off of surface water into the soil; or

(e)

If a permanent cathodic protection test station is not installed, an owner and permittee must have a written cathodic protection test procedure that has been developed in accordance with a nationally accepted code of practice. The written test procedure must:

(A)

Meet each of the minimum requirements established by subsection (d) of this section;

(B)

Contain sufficient detail to ensure that initial test conditions can be replicated during each test (i.e., electrical connections are made at the same points and the reference electrode contacts the soil at the same location);

(C)

Be followed for all cathodic protection tests at the UST facility; and

(D)

Be provided to DEQ upon request.

(5)

For USTs constructed of steel-and clad or jacketed with a non-corrodible material, an owner and permittee may use one of the codes and standards listed in Appendix F of this division to comply with this section of the rule.
