| "At 1910 hours on 7/23/00, the Safety Parameter Display System (SPDS)        |
| portion of the Emergency Response Facility Computer System (ERFCS) was noted |
| to be inoperable, due to all outputs being displayed in magenta color.       |
| Several attempts were made to reboot the system, but were unsuccessful.  The |
| air conditioning system for the Technical Support Center (TSC) computer room |
| (which houses the ERFCS) had failed earlier in the day, and the air          |
| conditioning system was secured to perform repairs.  Portable cooling fans   |
| were being used to cool the TSC computer room and the room temperature had   |
| stayed at about 80 degrees F.  The system must be secured if temperature     |
| rises above 85 degrees F.                                                    |

| "Repairs to the TSC computer room air conditioning system are continuing at  |
| this time.  A return to service time for the SPDS portion of the ERFCS has   |
| not been determined at this time."                                           |
