This attachment provides procedural guidance for controlling selected emergency response actions when their implementation would have adverse results.
Station Emergency Manager (SEM) approval is required before any required action is postponed, suspended or modified.
The guidance below is not all-inclusive.
UNANTICIPATED HAZARD EXISTS (e.g., security event, tornado or toxic release):
IF implementation of emergency response actions could compromise Security Plan response strategies, THEN consider postponing or suspending emergency response actions until threat has been resolved, e.g., on-site announcement directing assembly and emergency response facility activation, pager activation and call out per EPIP-3.05, AUGMENTATION OF EMERGENCY RESPONSE ORGANIZATION, dispatch of Security Team members to the LEOF per EPIP-3.04, ACTIVATION OF LOCAL EMERGENCY OPERATIONS FACILITY, and staging of road blocks per EPIP-5.04, ACCESS CONTROL.
IF assembling on-site personnel for accountability or activation of emergency response facilities could endanger plant personnel, THEN consider postponing emergency assembly until hazardous conditions are resolved.
(Consider having Corporate Security notify corporate emergency response organization only using CPIP-3.4, INNSBROOK SECURITY SUPPORT, and notifying personnel in unaffected areas on-site selectively.)
IF notifying augmentation could create a safety hazard for personnel coming to the station, THEN consider postponing augmentation notification.
(Consider having Corporate Security notify corporate emergency response organization only using CPIP-3.4, INNSBROOK SECURITY SUPPORT, or defering notifications until hazardous conditions are resolved.)
ANTICIPATED SITUATION (e.g., forecasted severe weather or grid disturbance):
IF all or part of the ERO has been staged in anticipation of a predicted
- event, THEN notify Security to omit performance of augmentation notification (as described in EPIP-3.05, AUGMENTATION OF EMERGENCY RESPONSE ORGANIZATION).
IF adequate controls have been established to continually account for personnel staged in anticipation of a predicted event, THEN notify Security to omit performance of initial accountability (as described in EPIP-5.03, PERSONNEL ACCOUNTABILITY).
IF a decision has been made to staff the Central EOF in lieu of the LEOF, THEN notify Security that performance of EPIP-3.04, ACTIVATION OF LOCAL EMERGENCY OPERATIONS FACILITY, is not required.
IF environmental conditions are hazardous, THEN consult with Security Team Leader about suspending procedural requirements for staging road blocks (IAW EPIP-5.04, ACCESS CONTROL).

MISCELLANEOUS GENERAL ASSUMPTIONS:
- Vent Vent:
Auxiliary Building, Air Ejector(s). Safeguards (filtered),
Fuel Building (filtered), Containment Purge (filtered), Waste Gas Decay Tank area.
- Process Vent: Waste Gas Decay Tanks, Containment Vacuum.
- Containment leakage:
MIDAS uses the higher of the two CHRRMS monitors to calculate the release.
- Air Ejector Monitors:
MIDAS adds the Air Ejector release to the associated vent vent release.
"* Main Steam and AFWPT: MIDAS adds the flows from each "open" and "status unknown" valve to calculate the total flow for a particular steam line.
MIDAS sums the releases from all three steam lines and AFWPT to calculate the total release.
"* For Vent Vents and Process Vents, MIDAS uses the highest radiation monitor indication on the affected pathway to calculate dose projections.
"* For "Quick Dose" defaults:
Unidentified mix, ground level, all release points active, and noble gas and iodine.
