November 13, 1973
Mr. Wayne L. Carlson, Engineering Inspector
Utah Public Service Commission
330 East Fourth South Street
Salt Lake City, UT 84111
Dear Mr. Carlson:
This is in response to your telephone conversation of November 8,
1973, with Mr. Bill Bertges of our office. You indicated that
there was an accident on November 7, 1973, that resulted in a
fatality during the construction of a new pipeline. You said
that the deceased fell from the pipe-laying tractor and was
crushed beneath the tracks. You inquired if even an incident is
reportable to our office pursuant to Part 191, 49 CFR.
This will advise that such an incident is not reportable to us
because it does not involve a pipeline leak as set forth in
§191.1.
We trust that this has answered your particular question. If we
can be of further assistance, please let us know.
Sincerely,
Joseph C. Caldwell
Director
Office of Pipeline Safety
