Program Auditable GALL Criteria Documentation of Audit Finding Element Program A. The program includes (a) preventive measures to mitigate Consistent with GALL AMP: Yes No Description corrosion, and (b) periodic inspection to manage the effects of Document(s) used to confirm Criteria:

corrosion on the pressure-retaining capacity of buried steel piping and tanks. Gray cast iron, which is included under the definition of steel, is also subject to a loss of material due to selective leaching, which is an aging effect managed under Comment:

Chapter XI.M33, Selective Leaching of Materials.

Preventive measures are in accordance with standard industry practice for maintaining external coatings and wrappings. Buried piping and tanks are inspected when they are excavated during maintenance and when a pipe is dug up and inspected for any reason.

This program is an acceptable option to manage buried piping and tanks, except further evaluation is required for the program element/attributes of detection of aging effects (regarding inspection frequency) and operating experience.

1. Scope of A. The program relies on preventive measures such as coating, Consistent with GALL AMP: Yes No Program wrapping and periodic inspection for loss of material caused by Document(s) used to confirm Criteria:

corrosion of the external surface of buried steel piping and tanks. Loss of material in these components, which may be exposed to aggressive soil environment, is caused by general, pitting, and crevice corrosion, and microbiologically-influenced Comment corrosion (MIC). Periodic inspections are performed when the components are excavated for maintenance or for any other XI.M34 Buried Piping And Tanks Inspection 1

Inspected of the external surface of buried steel piping and tanks.

Coatings and wrappings are inspected by visual techniques.

Any evidence of damaged wrapping or coating defects, such as coating perforation, holidays, or other damage, is an indicator of Comment:

possible corrosion damage to the external surface of piping and tanks.

4. Detection of A. Inspections performed to confirm that coating and wrapping Consistent with GALL AMP: Yes No Aging Effects are intact are an effective method to ensure that corrosion of Document(s) used to confirm Criteria:

external surfaces has not occurred and the intended function is maintained. Buried piping and tanks are opportunistically inspected whenever they are excavated during maintenance.

When opportunistic, the inspections are performed in areas with Comment:

the highest likelihood of corrosion problems, and in areas with a history of corrosion problems, within the areas made accessible to support the maintenance activity.

The applicants program is to be evaluated for the extended period of operation. It is anticipated that one or more opportunistic inspections may occur within a ten-year period.

Prior to entering the period of extended operation, the applicant is to verify that there is at least one opportunistic or focused inspection is performed within the past ten years. Upon entering the period of extended operation, the applicant is to perform a focused inspection within ten years, unless an opportunistic inspection occurred within this ten-year period.
