Ms. Evangeline Levison


Northern Natural Gas Company

2223 Dodge Street

Omaha, Nebraska 68102

Dear Ms. Levison:

Your letter of February 1, 1983, regarding your telephone conversation with Mr. Robert Langley on January 5, 1983, appears to adequately cover Mr. Langley's remarks to you.

As you mentioned, Northern Natural Gas must still comply with Subpart L, Operations, and Subpart M, Maintenance, of 49 CFR Part 192. The requirement of §192.703(b) has the greatest significance for the particular situation described. As was discussed, paragraph (b) states:

Each segment of pipeline that becomes unsafe must be replaced, repaired, or removed from service.

The determination of whether or not a particular segment of pipeline is unsafe and whether or not it is in compliance with Part 192 is made by the materials Transportation Bureau's Office of Operations and Enforcement (OOE) through a field office or a State agency. For this reason, a copy of this letter is being forwarded to the OOE Central Region Office in Kansas City, Missouri.

We trust this helps to further clarify our answer in this matter.
