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 Offsite Radiological Manager 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 Emergencv 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. Sectors / ERPA's are identified on Attachment 9.2.

5.2.3 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.

5.2.4 Re-evaluate the PARs based on the following:

5.2.4.3 Field data, 5.2.4.4 EPA PAGs - Attachment 9.3, 5.2.5 As protective action recommendations change, ensure appropriate steps are taken to protect the onsite population.

5.2.6 IF dose projections indicate a EPA PAG will be exceeded beyond 10 miles THEN send field teams to confirm projections and discuss possible protective actions with offsite officials if projections prove possible.

TEDE- Total Effective Dose Equivalent: Sum of external effective dose equivalent and committed effective dose equivalent to nonpregnant adults from exposure and intake during an emergency situation. Workers performing services during emergencies should limit dose to the lens of the eye to three times the listed value and doses to any organ (including skin and body extremities) to ten times the listed value.

TODE- Total Organ Dose Equivalent: Sum of external effective dose equivalent and committed dose equivalent (to the Thyroid).

(a) These actions are recommended for planning purposes. Protective action decisions at the time of the incident must take existing conditions into consideration.

(b) At the time of the incident, officials may implement low-impact protective actions in keeping with the principle of maintaining radiation exposures as low as reasonably achievable (ALARA)

Attachment 9.5 Basis for ERPA Selection in PAR Determination Sheet 1 of 2 The Emergency Response Planning Areas (ERPAs) provided in the Protective Action Recommendations (PARs) in this procedure are based on the following determinations:

The River ERPAs will always be included in each and every PAR issued by IPEC. The river is treated as one ERPA by the offsite authorities and is considered for closure early in a declared emergency at IPEC. These ERPAs are 42, 43, 44, 45, and 46.

When the conditions support Up-Valley Plumes (wind speed < 4 m/sec and wind direction from 1020-2090) 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). Affected ERPAs were determined to be those that have any portion within the affected Sector. 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 1020-2090) and either Pasqull Category C, D, E, F or 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 miles). Affected ERPAs were determined to be those that have any portion within the affected Sector. This was determined to be Sectors 16, 1,2 and 3.

When the conditions support Down-Valley Plumes (wind speed. < 4 m/sec and wind direction from 3400-1 01 0) 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 Isoplet h Lines touch beyond 2 miles). Affected ERPAs were determined to be those that have any portion within the affected Sector. 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 3400-1010) and either Pasqull Category C, D, E, F or 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 miles). Affected ERPAs were determined to be those that have any portion within the affected Sector. This was determined to be Sectors 7,8, 9 and 10.

(Affected Sectors are any Sector that the Isopleth Lines touch beyond 2 miles). Affected ERPAs were determined to be those that have any portion within the affected Sector, but not less than three Sectors. This was determined to be the Sector in which the Plume Centerline lays and 2 Sectors on either side of the centerline Sector.

Affected ERPAs were determined to be those that have any portion within the affected Sector, but not less than three Sectors. This was determined to be the Sector in which the Plume Centerline lays and 1 Sector on either side of the centerline Sector.
