O COORDINATION OF FIELD MONITORING ACTIVITIES 1.0 PURPOSE The purpose of this procedure is to provide guidance in directing field monitoring activ-4 ities and utilizing field information to determine the offsite doses.

2.0 RESPONSIBILITIES i

l 2.1 The Health Physics Coordinator (HPC) is responsible for ensuring Field Monitoring l

Teams are formed by the Radiological Controls coordinator, providing Dose Assessment results to the Emergency Coordinator for mak-ing Protective Action Recommendations, and providing direction to the Dose Assessment

' Coordinator.

2.2 The Radiological Assesasment Coordinator (RAC) is responsible for ensuring Field Moni-toring Teams and the Field Team Communicator i

O are requested through the Health Physics Coordinator.providing Dos'e Assessment l

e

'Results to the Recovery Manager for making protective action recommendations, and providing direction to the Dose Assessment L

Coordinator.

i i

2.3 The Dose Assessment Coordinator -(DAC) is

-responsible for directing Field Monitoring Activities, performing dose assessment b sed upon field results, and updating the Health Physics Coordinator / Radiological Assessment Coordinator on off site doses.- The Dose As-r sessment Coordinator shall ensure that dose projections are updated as needed, based on changes in radiological.and meteorological data.

3.0 INITIATING CONDITIONS 3.1 This procedure will be initiated at any time Field Monitoring Teams are to be formed and/or1 dispatched.

0 4.0 PROCEDURE 4.1 Forming Field Monitoring Teams 4.1.1 The Radiological Controls Coordinator should assign RadChem Technician (s) to Field Moni-toring Team (s) upon activation of the On-Site Emergency Organization.

4.1.2 The initial team (s) formed shall be in-structed to initiate EIP-ZZ-00223 and to standby in the EOF parking lot for further instructions.

4.1.3 The Health Physics Coordinator shall direct the Radiological Controls Coordinator to form Field Monitoring Teams, per EIP-ZZ-00220, Emergency Team Formation, when teams are needed, and request a RadChem Technician to fill the position of Field Team Communicator.

4.2 Directing Field Monitoring Activities 4.2.1 The Dose Assessment Coordinator shall direct O

Field Monitoring Team activities, via a Field Team Communicator.

The Dose Assessment Coor-dinator shall:

4.2.1.1 Ensure the implementation of EIP-ZZ-00223, Field Monitoring.

4.2.1.2 Instruct the Field Team Communicator to esta-blish contact with the Field Monitoring Teams and provide the following information:

4. 2.1.2.1 Affected sector (s) and locations to be sampled.

Specific sampling locations are dcaignated in EIP-ZZ-00223, Fiald Monitoring.

NOTE The initial sampling location should be that sampling loca-tion at the EAB nearest to the plume centerline, in or-der to verify the emergency classification.

Subsequent locations should be chosen based on factors such as topographical features and wind direction changes, in order to locate t.he plume centerline (highest concentration).

4.2.1.2.2 The type of measurements to be taken (e.g.

dose rate, count rate, I-131 analysis, etc.).

-s

'\\ l 4.2.1.2.3 The type of samples to collect (e.g. air, iodine, water, vegetation, etc.).

4.2.1.2.4 Instruction to don protective clothing and respiratory protection when radiological con-ditions warrant such actions.

4.2.1.2.5 Locations and individual to which samples shall be delivered.

NOTE Samples shall normally be taken to the EOF Laboratory for storage and further analysis if necessary.

4.2.1.2.6 Debriefing instructions when Field Monitoring Activities are complete.

0 4.3 Plume Tracking To determine the plume dimensions the Dose Assessment Coordinator shall instruct the Field-Monitoring Teams to report any increase in count rate or dose rate on survey instru-mentation during transit.

4J3.1 To find the plume-centerline and plume edges Field Monitoring Teams should be instructed to drive through the suspected plume location L

observing-the survey instruments, noting the changes in readings and locations.

-4.3.2 Sampling locations specified in EIP-ZZ-00223 can be modified based upon suspected or ac-tual plume location.

4.3.2.1 Air particulate sample, iodine sample, noble gas sample, ground level survey and area dose rates should be taken at the plume centerline.

4.3.3 Teams should zig-zag through the suspected j

"')

plume to monitor any changes in the plame l

s-centerline or edges.

l l

4.4 Dose Assessment 4.4.1 The Dose Assessment Coordinator shall update dose assessment based upon field monitoring data.

L 4.4.2 Enter field monitoring sampling data on At-tachment 2, Dose Assessment Worksheet, or if an isotopic analysis was performed enter iso-topic concentrations on Attachment 3, Dose Rate Calculation Worksheet.

NOTE The data used. to perform this dose assessment should be

.from the plume centerline.

\\pl 4.4.3 Determine the stability class using the Delta-T on Attachment 2 and circle the entire column (Delta-T to the last Xu/Q value).

4.4.3.1 If Delta-T is not available the stability class can be determined utilizing the wind deviation from the secondary meteorological tower and Attachment 1, Stabilitp Class Determination.

Circle the entire column un-der the appropriate stability class on At-tachment 2.

1 4.4.4 Select the correct survey location Xu/Q for the location at which the measurements or sample was taken.

This can be obtained from the Xu/Q values on Attachment 2 or from At-tachment 1 if the survey location / distance is not given on Attachment 2.

4.4.5 Enter the correct survey location Xu/Q, whole body dose rate, and I-131 concentration on.

4.4.6 Enter the correct Dose Equivalent Factor.

\\-

4.4.7 Perform the calculation as indicated on At-tachment 2.

4.4.8 If an isotopic analysis was performed on a noble gas sample and/or an iodine cartridge perform the calculations on Attachment 3.

l 4.4.8.1 Transfer the calculated whole body dose rate from Attachment 3 to Attachment 2 and perform i

the calculations on Attachment 2, utilizing l

Steps 4.4.2 through 4.4.6.

4.4.9 Compare the dose rates and cumulative dose to the Protective Action Guidelines and Emergency Action Levels, using Attachment 4, Protective Action Recommandations and Emergency Action Levels, as guidance, to determine if any change in Emergency Action Levels or Protective Action Recommendation is required.

4.4.10 Inform the Health Physics Coordinator or Radiological Assessment Coordinator if any change in Emergency Action Levels or Protec-tive Action Recommendations required.

4.4.11 Update the status boards based upon Field Monitoring Data.

Ensure any changes on status boards are relayed to the TSC or EOF as appropriate to keep status boards consistent.
