Engineering calculations, however, show the installation will remain functional following an Operating Basis Earthquake (OBE). In addition:
Interim corrective measures, as discussed in Reference 1, to eliminate the potential for water accumulation in the ofTgas system 48 inch hold up line will remain in place until the installation is fully qualified.
Contingency measures currently in place to restore power to the sump pumps using temporary cables will remain in effect until the installation is fully qualified.
