A1TACHMENT 3 LIST OF COMPONENTS IN FIRE ZONES 98J AND 99M Shortly after the inspection, Region IV requested a list and description of cables and components located in Fire Zones 98J and 99M. On August 28, 2001, the licensee provided this list. Because of its late arrival, Region IV did not consider all the components shown on the list in the Phase 2 SDP. It is provided with this TIA memo for use in performing the Phase 3 SDP. Please note that the list is not train specific and does not distiguish between power and control cables.
