Or. Admin. R. 340-150-0350 - UST System Repairs

(1) Repair methods. An owner and permittee must repair UST system components according to the manufacturer's specifications and perform repairs in accordance with a code of practice developed by a nationally recognized association or an independent testing laboratory. The codes and standards listed in Appendix H of this division may be used to comply with this section. [Note: View a PDF of the appendix by clicking on the "Tables" link below.] A manufacturer's authorized representative may make repairs to fiberglass or other nonmetallic USTs.
(2) Lined tanks. An owner and permittee of a tank that has been previously repaired or upgraded using the interior lining method may repair the tank by restoring or adding additional lining to the tank if the metal portion of the tank has been determined to be structurally sound by use of the integrity assessment (inspection) method specified by American Petroleum Institute RP 1631, "Interior Lining and Periodic Inspection of Underground Storage Tanks." An owner and permittee must permanently decommission a tank if the integrity assessment determines that the tank is no longer structurally sound.
(3) Tanks. Before operating a repaired tank, an owner and permittee must:
(a) Have the tank tightness tested after the repair is complete and report to DEQ any test failures (OAR 340-150-0445); and
(b) For all repaired tanks except those repaired by lining, obtain written documentation that the original manufacturer has recertified the repaired UST as meeting current UST performance requirements. If the original manufacturer is not available (e.g., no longer in business, unknown, etc.) another manufacturer of the same tank brand or type must certify in writing that the tank meets the current UST performance requirements.
(4) Piping. Before operating repaired underground piping, an owner and permittee must have the underground piping tightness tested after the repair is complete and report to DEQ any test failure (OAR 340-150-0410).
(5) Corrosion protection. An owner and permittee must have a cathodic protection system tested within six months following a repair to ensure proper operation and report to DEQ any test failure (OAR 340-150-0325).
(6) Record keeping. An owner and permittee must maintain records that demonstrate compliance with the requirements of this rule for the remaining operating life of the UST system. Records must include information such as a description of the work, date performed, name and address of the company that performed the work, equipment model number (as appropriate), test results and any other related data. An owner and permittee must make the records available for review by DEQ upon request.
