Mr. B.H. Blackmon
President, Cook Inlet Pipe Line Company
P.O. Box 900
Dallas, TX 75221
Dear Mr. Blackmon:
Your letter dated October 25, 1982, concerned the maximum operating pressure for a segment of the
Cook Inlet pipeline system and asked whether a reduction in operating pressure is an acceptable
remedy for corrosion pitting. You referred to an interpretation of §§195.416(f) and (g) given to
Williams Pipe Line Company on August 16, 1982, and asked whether your understanding of that
interpretation is correct.
The referenced interpretation says in rather lead-footed terms that a reduction in operating
pressure, commensurate with the remaining pipe thickness, is an acceptable remedy for general
corrosion under
§195.416(f) as well as isolated corrosion pitting under §195.416(g).
Your understanding of that interpretation is correct as given in your letter. Please be advised,
however, that maximum operating pressure is limited by all of the requirements of §195.406.
Sincerely,
Original signed by Richard L. Beam
