3 1.0 APPLICABILITY This procedure applies to all emergency situations when environmental mnitoring and dose assessment is necessary, and Environmental Monitoring Teams have been dispatched.
2.0 PRECAUTIONS s
2.1 Accurate recording of data acquired fran the Radiological Protection
~
Director (RPD) or Environmental Monitoring Team (EMT) Coordinator is essential.
2.2 All conclusions drawn fran envirormental data must be accurately documented.

4.1.2 Compare these results for all points of interest to TABLES ENV-3H.1 as follows:
TABLE ENV-3H.1: Tcke the projected Dose (s) and enter the chart at tne appropriate level by projected Doses listed in the lef t hand column. Read across from the Doses and obtain the corres-pending Recommended Actions and comments.
NOTE: EPA guidelines state that protective action recommendations should be based on the projected child thyroid dose.

4.1.3 Record the impact times on the Field Maps at the points of interest.
4.1.4 Evaluate the impact time, plant conditions (past, present and ?
future), weather conditions, and evacuation time estimates, and determine the most beneficial and appropriate Protective Actions the public can take to reduce their exposure.
4.1. 5 Verify previous recommendations, if any are still valid, for any new data that is now available.
4.1.6 Report Protective Action Recommendations to the Emergency Response Manager.
4.1.7 Repeat steps 4.1.2 through 4.1.6 as necessary as new infomation is received from the Environmental Monitoring Teams.
4.2 Long Term Protective Action Determinations

)
4.2.1 Obtain data from the results of ground deposition samples
' (V reported by the Environmental Consultant.
l 4.2.2 Compare these results to Table ENV-3H.2 to determine the I
appropriate Protective Action Recommendations as follows.
l Table ENY-3H.2:
Section I, Part A: Compare the projected dose above ground, Ground Contamina. tion level measurements, or exposure rates 1 meter above ground and at or above these base limits proceed to Part B for the Recom:mnded Protective Actions.
Section II, Part A: Evaluate the results of the Environmental Consultant. The results of a specific nuclide concentration (I-131, Cs-137, Sr-90, and/or Sr-89) and the medium in which it was obtained are listed for comparison against the reported resul ts. For example, if a milk analysis was reported by the '-
I l
Environmental Consultant at 0.012 uc/ml of I-131, proceed to the I-131 column under the heading Nuclide. Then read to the i
right for the Action Levels and concentrtion in Hilk & Water Preventive or Emergency Levels, and compare the levels to the reported result.
If the Reported result is less than the preventive level, no protective action is necessary. If the results are higher than the preventive or Emergency level, then proceed to the next page and recommend the listed protective action recommendations, as in the example, the reccomendations under preventive level.
