Dear Mr. Kleis:
In reply to your letter of July 27, 1969, active corrosion is defined in Section 192.457(c) as
corrosion which, unless controlled, could result in a condition that is detrimental to public safety.
As covered by Section 192.457(b), the operator shall determine the areas of active corrosion by
electrical survey, or where electrical survey is impracticable, by the study of corrosion and leak
history records, by leak detection survey, or by other means.
In the discretion of the individual gas operator, any type of electrical survey he may wish to use
that will reveal active areas of corrosion is satisfactory. It is not the policy of the Office of
Pipeline Safety to recommend any one electrical method over another.
I trust this response will be helpful.
Sincerely,
/signed/
Joseph C. Caldwell
Acting Director
Office of Pipeline Safety
