system, and what is required to maintain it, than any other organization. In the
past we have been thorough about documenting failures, determining their
causes, and implementing measures to improve our design, construction and
operating procedures. We have learned from this activity, over a period of 32
years, what deterioration mechanisms reduce the structural integrity and
where they are likely to cause future problems. The experiences of other
pipeline operators, and our active participation in research and development,
have also provided information relevant to understanding the structural
integrity of our system. Although we believe we know more about this subject
for our system than anyone else, and have developed a sound approach to
pipeline integrity planning and maintenance, we also recognize aspects of
our programme that can be improved, and will continue to refine the
approach.

GOAL OF PIPELINE INTEGRITY PROGRAMME

The primary goal of the programme is to prevent structural integrity
problems from having a significant effect on public safety or business
operations by identifying and performing those inspection, monitoring and
repair activities that can be most effective. The secondary goal is to commu-
nicate the programme within our company, and to other interested parties,
to improve the programme, and to establish knowledgeable support for it.
