This standard presents acceptable methods for the design, installation, operation, and maintenance of deep anode systems that discharge impressed current for cathodic protection (CP) of underground or submerged metallic structures.

This standard is based on the best available technology and methods that have been used successfully by experienced corrosion engineers.

This standard does not designate methods for every specific situation because the complexity of some environmental conditions precludes standardizing all design and installation procedures.

The provisions of this standard should be applied under the direction of a competent corrosion engineer. The term “corrosion engineer,” as used in this standard, refers to a person who, by reason of knowledge of the physical sciences and the principles of engineering and mathematics acquired by education and related practical experience, is qualified to engage in the practice of corrosion control of underground or submerged structures.

Other types of anode systems should be investigated before the decision is made to use a deep anode system, because alternatives that are more economical may be available.

Codes, laws, and regulations in a local geographic area may require supplements to or deviation from this standard.

Necessary precautions must be taken to prevent damage to existing underground structures and deleterious modification of groundwater quality.

Adequate records containing information showing site right-of-way, installation procedures, operation data, maintenance, repair, and test records should be maintained.
