A. Plant and Station Logs
Records of all system operations shall be maintained at each attended or remotely controlled
powerplant, designated major pumping plant, pumping- generating plant. At part-time attended
facilities, records shall be kept for the period of attended operation. At unattended facilities, records
shall cover each visit to the facility.
powerplant, designated major pumping plant, pumping- generating plant. At part-time attended
facilities, records shall be kept for the period of attended operation. At unattended facilities, records
shall cover each visit to the facility.
A logged record shall be maintained either by the dispatchers, operators, or switchmen on duty.
At some locations, portions of the information will be available from automatic recording and
monitoring equipment. Specific data may vary in form and content to fit the needs and conditions
of Individual plants or stations. In general, the data shall include information on loading, voltage,
temperatures of major facilities, water elevations and discharges, transmission line disturbances,
outages, clearances, etc., to provide a continuing record of operation for future reference, as well
as clues to the possible cause of equipment trouble or abnormal operating conditions.

When automatic recording and monitoring equipment is not provided, and to supplement such
Information, a plant or station log shall be maintained in a bound book. A sample page from a bound

This book is applicable for use in attended, part-
Operating Log (form 7-1679) which may be more appropriate for use at certain facilities.
All entries in the bound log books shall be make in ink or other indelible writing material.
Corrections shall not be made by erasure or use of ink eradicators. However, errors may be lightly
crossed out so the incorrect notation is still legible, and the correct entry added. The log shall
contain a chronological record of all important events such as starting and stopping of machines,
switching operations, issuance and release of clearances, operation of outlet works or spillways,
trouble experience, etc. The logging of clearances issued or released shall be in compliance with
FIST Volume 1-1 "Power System Clearance Procedure". Switching Program Forms shall be
considered part of the station log, and shall be accessible at all times, except when in use in the
performance of switching operations.

At unattended stations, log entries shall indicate the date and time of each visit; describe any
unusual conditions observed or nonroutine work performed; record Information from automatic
equipment such as relay targets, operation counters on circuit breakers or voltage regulating
devices, etc.; and be signed by the person making the entry.
