Memorandum
March 2, 1995
INFORMATION: U.S. Oil Interpretation
Cesar De Leon
Deputy Associate Administrator for Pipeline Safety
Ivan Huntoon
Director, Central Region
This responds to your memo of February 9, 1995, regarding our January 30, 1995, letter to Mr.
Thomas J. Sullivan, consultant for the U.S. Oil Company. We advised Mr. Sullivan that the Part
195 regulations cover the company’ s pipelines outside the terminal, except for a pipeline
transporting calcium chloride. Your memo asks whether, before the 20% SMYS amendment,
Part 195 applied to a low-stress line segment between the West Shore connection and the
terminal. You believe Part 195 did apply since the line segment serves as a continuation of West
Shore’ s pipeline, which operates at more than 20% SMYS.
We have interpreted the low-stress exclusion to apply only to pipelines that operate entirely at
20% SMYS or less. So, for Part 195 to have applied to the line segment in question, the segment
would have had to have been part of a pipeline that operated above 20% SMYS. Although Part
195 does not define the beginning and end of pipelines, it does place the burden of compliance
with the regulations on persons who own or operate pipelines. Therefore, in the absence of any
other demarcation of pipelines under Part 195, the only reasonable way to apply the low-stress
exclusion is on the basis of pipeline ownership or operation. Using this approach, because the line
segment in question was owned and operated separately from the West Shore pipeline, the
segment was not under Part 195 before the 20% SMYS amendment.
