. PVNGS EMERGENCY PLAN Qceouse IMPLEMENTING PROCEDURE EPIP-15 REVISION PROTECTIVE ACTION GUIDELINES 4 Page 5 of 13 3.2- Protective action recommendations are based on plant and containment conditions and these recommendations are made even
. when no release is in progress. These recommendations are transmitted to government officials using EPIP-03, and
" NOTIFICATION OF UNUSUAL EVENT Implementing Actions" EPIP-04,
" ALERT, SITE AREA and GENERAL EMERGENCY Implementing Actions."
3.3 Protective action guides represent trigger levels and are not intended to represent acceptable dose levels.
3.4 PAGs for the general public are given in ranges. The lowest dose values should be used if there are no major local constraints in providing protection at this level. Local constraints may, however, make the lower values impractical to use, but in no casa should the higher value be exceeded in determining a need for protective action.
3.5 The projected dose and affected offsite areas depend upon the
( curies released, release rate, duration of the release,-
isotopic mixture of the release (varies with effective age) and meteorological conditions.
3.6 At times, selection of protective actions should be considered subjectively as conditions beyond the scope of this procedure may exist.
3.7 When the wind is blowing into the Palo Verde Hills (sectors N, P or Q) and protective actions are being considered, the two sectors on either side of the affected sector shall be included in the recommendation (e.g., a plume in sector P shall require consideration of sectors M, N, Q and R in the recommendation.)
3.8 Protective actions recommended to state authorities by ANPP SHALL NOT be transmitted to the JENC. -
3.9 Government officials should inform EC/EOD prior to implementing protective actions.
3.10 If actual airborne radioactivity, noble gas or iodine sample results are available (either from RMS filter analysis or field measurements) this information may be used instead of dose projections for making protective action recommendations.

" Initial Dose Assessment." This dose estimate is referred to as the projected dose. A protective action is an action taken to avoid or reduce this projected dose when the benefits derived from such action are sufficient to offset any undesirable features of the protective action.
4.1.2 The Protective Action Guide (PAG) is based on the projected dose to individuals in the population which warrant taking protective actions. It is used in an effort to minimize the risk from an event which is occurring or has already occurred.
( 4.1.3 The responsibility for the decision to notify and recommend protective actions to the appropriate authorities' belongs to the Emergency Coordinator until he is relieved of this responsibility by the Emergency Operations Director.
4.1.4 The Radiation Protection Technician of the affected unit shall be responsible for initial offsite dose calculations and/or projections. -
4.1.5 The Radiatien Assessment Coordinator (Radiation Protection Monitor, on shift) shall be responsible for updating and refining dose assessments for critical receptor site locations and evalur'.ing appropriate protective actions.
4.1.6 The Radiological Protection Coordinator (Radiological Assessment Coordinator) shall be responsible for relaying -
dose assessment and protective action evaluations to the Emergency Coordinator (Emergency Operations Director).
4.2 Prerequisitas 4.2.1 Projected whole body and thyroid dose rates and integrated dose for critical receptor site locations have been calculated in accordance with EPIP-14B, and such doses warrant evaluating, and if necessary, recommending protective actions.

4.3.1.1 Evaluate current plant status with respect to potential for releases or increased releases.
4.3.1.2 Update and refine dose estimates for critical receptor site locations upon significant changes in one or more of the following parameters:
(1) Release rates.
(2) Duration of the releases.
(3) Isotopic mixture of the release (varies as a function of effective age).
(4) Meteorological conditions.
4.3.2 Should the plant status or projected doses indicate that sheltering or evacuation be considered per Appendix A, determine the effectiveness of these protective actions as described below. Time estimates should be obtained from the State Emergency Operations Center.
4.3.3 Evacuation Effectiveness - The effectiveness of evacuation in limiting radiation dose is a function of the time of exposure if a plume is present. This is dependent upon the time required to evacuate. The evacuation time T(EV) is expressed as:
T(EV) = TD+ N+ M+ T Where:
T = Time delay measured from the point' of the D
protective action recommendation from the facility to government to evacuate to the actual decision by the competent authority to order the evacuation.
T N
=
Time required by officials to notify people to evacuate.
Tg = Time required for people to mobilize and get under way.

4.3.3.3 Under the following conditions evaluate the benefits of sheltering vs. the benefits of avacuation.
(1) In cases where there is no tien to evacuate prior to the arrival of the plume.
(2) The projected evacuation time and time before plume arrival are nearly equal.
4.3.3.4 If evacuation appears to offer a significant reduction in dose (greater than sheltering) recommend evacuation to the appropriate county and/or state officials.
4.3.4 Sheltering Effectiveness 4.3.4.1 If evacuation does not offer significant dose
