DESCRIPTION OF EVENT On February 26,1997, it was discovered that the 60-meter wind direction transmitter was out of orientation with true north by approximately 25 degrees.
The transmitter was promptly, and correctly, reoriented. This discovery was the result of an investigation of discrepancies between records of wind directions plotted for the 60-meter wind direction transmitter versus records of wind directions for the 10-meter wind direction transmitter. The 60-meter wind direction transmitter was improperly oriented due to an inaccurate true north reference marker on the tower, believed to have been shifted during tower maintenance in July 1996. No radiological events have occurred during the period of time involved that relied on the accuracy of this transmitter to evaluate exposures.
