PLANT SYSTEMS 3/4.7.5 FLOOD LEVEL LIMITING CONDITION FOR OPERATION 3.7.5.1 At least one OPERABLE service water pump motor shall be protected against flooding to a minimum elevation of 28 feet Mean Sea Level USGS datum if either:

L. The water level, including wave crest height, is exceeding plant grade level (14.0 feet Mean Sea Level USGS datum), or

b. Three or more of the following conditions are occurring simultaneously:
1. The center of a storm, as determined by radar, reconnaissance, or forecasted track projection, is presently located within the critical area as defined on Figure 3.7-1.
2. The projected track of a storm approaching the facility as determined by radar, reconnaissance, or forecasted track projection, lies between 1300 and 3500
3. The central pressure of the storm is or is forecasted to be _

28.0 in. Hg; or the measured 15 minute average wind speed at nominal elevation 389' on the meteorological tower exceeds 60 mph.

4. The 15 minute average wind direction at nominal elevation 389' on the meteorological tower is within the sector from 1500 clockwise to 3000 APPLICABILITY: ALL MODES ACTION:

With the water level exceeding either plant grade or with three or more of the above specified meteorological conditions occurring simultaneously, immediately initiate action to protect at least one service water pump motor against flooding to a minimum elevation of 28 feet; complete this protective action within 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.
