2.0 REFERENCES
EPA Protective Action Guidelines 3.0 DEFINITIONS Protective Action Recommendations (PARs) -Specific recommendations made by the Emergency Director to the local authorities in accordance with Emergency Plan procedures based on Protection Action Guidelines.
4.0 RESPONSIBILITIES 4.1 The Shift Manager is responsible for evaluating accident conditions, classifying the accident, and recommending protective actions to offsite authorities during the initial phases of the accident.
The Emergency Director assumes these responsibilities when he takes control of the emergency response from the Shift Manager. The Radiological Assessment Coordinator will assist the Emergency Director with protective action recommendations.
4.2 The decision to initiate any protective actions is solely the responsibility of the local authorities.
5.0 DETAILS 5.1 NUE. Alert. Site Area Emergency Recommend no protective actions be taken. 5.2 General Emergency 5.2.1 The initial protective action recommendation should be made within 15 minutes of the GENERAL EMERGENCY declaration.
5.2.2 Protective Action Recommendations (PARs) shall be made in accordance with Attachment 9.1. Downwind Sectors are identified on Attachment 9.2. 5.2.3 Downwind sectors in Attachment 9.2 are determined using MIDAS wind fields. If MIDAS is unavailable, the isopleth overlays may be used as backup (Use Attachments 9.4 and 9.6 to support isopleth and sector selection)
NOTE: Due to the wind field origin change between MIDAS and the isopleth overlays there is a difference in the down-valley plume shape. When using the overlays as a substitute for MIDAS, down-valley PARs may be different by one sector.
e IPEC NON-QUALITY RELATED IP-EP-410 Revision 7 = Entergy. EMERGENCY PLAN PROCEDURE IMPLEMENTING PROCEDURES REFERENCE USE Page ! 01 11 5.2.4 The initial PAR shall be made in the first GENERAL EMERGENCY notification to the State/Counties.
All subsequent, Part I notifications shall include the latest PAR. 5.2.5 Re-evaluate the PARs based on the following: (Attachment 9.7)
- Changes in Wind Direction or Speed
- Dose Assessment
-(When release duration is NOT ab l e to be est i mated, use four hours as a default value),
- Field Data
- Plant Conditions 5.2.6 As protective action recommendations change, ensure appropriate steps are taken to protect the onsite population.

- When the conditions support Up-Valley Plumes (wind speed. 4 m/sec and wind direction from 102°-209°)
and either Pasquil Category A or B is in effect, the MIDAS display and appropriate overlay were viewed on the map and the affected Sectors were determined (Affected Sectors are any Sector that the Isopleth Lines touch beyond 2 miles). This was determined to be Sectors 16, 1,2 , 3 and 4. When the conditions support Up-Valley Plumes (wind speed. 4 m/sec and wind direction from 102°-209°)
and either Pasquil Category C, 0, E, F or G is in effect, the MIDAS display and appropriate overlay were placed on the map and the affected Sectors were determined. (Affected Sectors are any Sector that the Isopleth Lines touch beyond 2 miles). This was determined to be Sectors 16, 1, 2 and 3. When the conditions support Down-Valley Plumes (wind 4 m/sec and wind direction from (349-101 for MIDAS and 340°-101° for overlay) and either Pasquil Category A or B is in effect, the appropriate overlay was placed on the map and the affected Sectors were determined. (Affected Sectors are any Sector that the Isopleth Lines touch beyond 2 miles). This was determined to be Sectors 7, 8, 9 , 10 and 11. When the conditions support Down-Valley Plumes (wind speed. 4 m/sec and wind direction from 349-101 for MIDAS and 340°-101° for overlay) and either Pasquil Category C, 0, E, For G is in effect, the appropriate MIDAS display or overlay was placed on the map and the affected Sectors were determined. (Affected Sectors are any Sector that the Isopleth Lines touch beyond 2 miles). This was determined to be Sectors 7,8,9 and 10. When the conditions support Cross-Valley Plumes (wind speed. > 4 m/sec OR wind direction from 210°-348 for MIDAS and 210-339° for overlay) and either Pasquil Category A or B is in effect , the appropriate MIDAS display or overlay was placed on the map and the affected Sectors were determined. (Affected Sectors are any Sector that the Isopleth Lines touch beyond 2 miles). This was determined to be the Sector in which the Plume Centerline lays and 2 Sectors on either side of the centerline Sector. When the conditions support Cross-Valley Plumes (wind speed. > 4 m/sec OR wind direction from 210°-348 for MIDAS and 210 -339 for overlay) and either Pasquil Category C, 0, E, F and G is in effect , the appropriate overlay was placed on the map and the affected Sectors were determined. (Affected Sectors are any Sector that the Isopleth Lines touch beyond 2 m i les). This was determined to be the Sector in which the Plume Centerline lays and 1 Sector on either side of the centerline Sector.
