SECTION 3: EVACUATION MONITORING

a. Proceed to the assigned Reassembly Control Point/Monitoring Station (established at: Access Road; Parking Lot of Van Buren State Park; or, Parking Lot of Covert Township Park) and ascertain habitability prior to establishing the monitoring station. If personnel cannot be deconned at the selected location, they should be sent to

.the Allegan Service Center. Reference Emergency Implementing Procedure El-13, "Evacuation/Reassembly," for guida.nce. Contact the OSC so that arrangements can be made for use of the Allegan Service Center.

b. El-13, "Evacuation/Reassembly," implemented: Personnel surveyed, dosimeters read, dosimetry collected, etc .

e. Data reported to OSC or EOF.

SECTION 4: PLUME TRACKING NOTE: The following guidan~e is an aid only in initially locating and following the plume. Actual data on location parameters should. be. compared and reported as soon as possible.

a. Using given meteorol.ogical data and the 10-mile Emergency Planning Zone (EPZ) map, a fair idea can be quickly obtained of the possible location of the plume. Using the wind speed and time from release data, the leading edge of the plume can be projected and followed .

DCC: 950/22*06 *

  • Proc No El'~9 Attachment 1 Revision 9
  • Page 4 of 6 OFFSITE MONITORING TEAM LIST
b. Traverse the plume to determine outer boundaries, centerline, and respective dose rates.
1. The survey instrument should be held at an open window of the vehicle, the meter monitored continuously. *
2. When an increase in dose rate is noted, record the odometer reading, relative map location, dose rate, and time. (When an air sample is taken,. all data should be recorded on Attachment 2.)

3.* Continuing slowly, record dose rate increases and odometer readings to the centerline of the plume, where *the dose rate will be at a maximum, periodically checking open vs closed beta window dose rates for the presence of the plume at ground level.

4. At the centerline, unless high dose rates prohibit, obtain an air sample (iodine and particulate) and. survey for dose rates at thr~e inches and three feet from the ground. Check open and closed beta window dose rates, and take smear(s) for loose surface contamination. If centerline open/closed window readings indicate there is no ground level plume present, the air sample and surface contamination survey may be. omitted.

..., Record all data on Attachment 2.

5. Continue to the opposite plume boundary, noting dose rates and odometer readings, and finally, the relative map location of the outer boundary.

c.* When traversing the plume, keep vehicle windows and vents closed, except for that necessary to take dose rate readings en route.

Avoid dusty, gravel, or dirt roads when traversing the plume.

Periodically perform personnel and vehicle interior surveys for contamination in a low background area. If minor contamination is found, decontaminate, if possible. Record data on Attachment 5.

Gross vehicle and personnel decontamination should not be attempted until the team is recalled. Report gross contamination results to the OSC or EOF for guidance and ultimate location for d.

Vehicle and/or Personnel decontamination.

When traversing or sampling in a ground level plume, evaluate necessary protective clothing.

  • Proc No El-9 Attachment 1 Revision 9 Page 5 of 6 OFFSITE MONITORING TEAM LIST
e. Check self-reading or electronic dosimeters frequently (ie, entry into plume, exit from plume), record times and dose received, and report to the OSC or EOF. Dose received per plume entry in addition to previous dose received in the current year should be closely tracked to ensure authorized dose control levels are not exceeded.

SECTION 5: AIRBORNE SAMPLING AND CONTAMINATION SURVEYS

a. Field collection under emergency conditions should be a 5 ft 3 sample, normally obtained by taking a 2 cfm sample for 2.5 minutes. A shorter sample would be appropriate in the presence of high dose rates.
b. Complete Sections 1 and 2 of Attachment 2 to document dose rates, contamination levels and air sample data to determine corrected volume. Section 1 is to be completed for every air sample taken .
  • c. Carefully remove filter and cartridge. Mark the direction of air flow on the silver zeolite cartridge with an arrow. Handle filters with care to prevent cross contamination or loss of collected material, using tweezers when possible.

NOTE: If time constraints do not permit completion of calculations, transmit count rate data to the OSC or EOF by mobile radio.

d. Perform initial gross analysis using a PRM-6 count rate meter with an HP 210 probe, or equivalent.
e. Field determination of particulate Airborne Activity:
1. Determine the background count rate with the HP-2] 0 probe, or equivalent, in place on the sample holder.
2. Place the particulate filter in the sample holder, upstream side up. With the HP-210 probe, or equivalent, in place on the holder, the filter should be approximately Yz inch from the detector .
  • 3.

4.

Determine the gross particulate count rate.

Complete Section 3 of Attachment 2.

5. Place the sample in a bag or envelope, label with date, time sample started and ended, average flowrate, location sample was taken, and initial.
f. Field determination of gross Iodine Activity.
1. Determine the background count rate with the HP-210 probe, or equivalent, in the counting area.

11 NOTE: Backside readings at % are preferred, but if count rate is negligible use the frontside at Y2 11

2. Determine the gross iodine count rate by placing the 11 HP 210 probe, or equivalent, % from the backside of cartridge.
3. Complete Section 4 of Attachment 2.

g.

4. Place the cartridge in a bag, label same as for the particulate filter.

Save all. samples for further/future analysis, storing high level samples in a shielded area.

h. Reevaluate protective measures necessary (protective clothing) based on determined airborne activity levels.
