INTRODUCTION AND PURPOSE
General Guide
This bulletin summarizes current policies for power operations and maintenance
improvement. Effectiveness of the improvement program should constantly be
evaluated and substantial modifications of the material given here can occur.
Consequently, information in this bulletin is to be considered as a general rule and
may be superseded by subsequent correspondence and supplemented by individual
project needs.
Need for Incident-free Performance
The modernization programs and applications of new technology has produced
significant changes in operational modes and increased complexity of systems. With
emphasis on automation and remote control, personnel are experiencing less direct
contact with equipment and are becoming less familiar with its operation. Unfamiliarity
and reduced contact creates greater potential for misoperation of equipment.
Consequences of misoperation or misuses are now multiplied due to expanded
systems interconnections and increased public scrutiny of mistakes. One small
mistake by an individual may have impact on electrical service in several states.
Program Objective
Experience has shown that a percentage of system outages have been the result of
human incident. Since the consequences of these incidents can be very costly either
in terms of equipment damage, lost revenue, or jeopardy to life and property, it is
necessary to place emphasis on a program to eliminate or reduce all incidents. The
objective of this program is incident-free performance throughout the Bureau of
Reclamation through adequate training, improved communications, and adequate
facilities.
Attaining Incident-free Performance
It is recognized that in systems as large and complex as today's water and power
facilities, it may not be realistic to expect that all O&M incidents can be eliminated.
However, by using incident-free performance as a goal, and every incident
demonstrating the need for a solution to a problem, and by diligent pursuit of these
solutions, the frequency of incidents can be reduced. It has been possible in given
areas to attain incident-free performance over prolonged periods. A very practical
