Subject: Change in Technical Specification (TS) Rquirements on Emergency
         Diesel Generator (EDG) surveillance requirements


Discussion:

The version of the new standard technical specification adopted by the
licensee required semi-annual surveillance of EDGs to demonstrate
acceptable voltage between 3744v and 4576v, and the frequency to range
between 59.5 and 60.5Hz within 10 seconds of starting from standby
conditions.  The licensee was unable to meet this condition on EDG
performance.  The NRC had revised this requirement in later editions of
the standard TS to have the minimum voltage and frequency achieved in 10
seconds but without the 10 second limitation for reaching the steady
state voltage and frequency.

The EDG capability to achieve steady state voltage would still need to be
trended to identify degradation of governor and voltage regulator as
discussed in the standard TS bases but achieving steady state in a
specific time is no longer an LCO (limiting conditions for operation)
requirement.

The licensee was granted an enforcement discretion to remain at power
while the TS amendment was processed.
