a. Select the appropriate DCGL for each Radionuclide of Concern (ROC) based on the corresponding SEA and the Uniform Conceptual Site Model (CSM).

o If Tc-99 was measured during the charadsrizationiRASS survey, then the "Measure Tc-99" DCGIJ will be used from Appendix A of HDP-PR-FSS-70f.

o If Tc-99 was not measured in the characterization/RASS survey, then the modified U'235 DCGL

("Infer Tc-99") will be used from Appendix A HDP-PR-FSS-701.

NOTE: The Uniform DCGL will be used to calculated the number of samples in the statistical survey population.

8. Calsrlat the Number of Samples ln the Stadstical Surrey Populadon NOTE: The Stdistical Survey Population is rodinely derived based on the Uniform DCGL.

o Alternatively, if the Strrvey Unit excavation extends into multiple CSMs (e.g. surface, root &

deep), then the DCGt"(s) from the most limiting strata can be trsed with the equations below; OR o If the excavdion significantly extends into the deep strata" then the alternate approach presented in section 8.2.5 of HDP-PR-FSS-701 may be used for determining the mean SOF and weighted standard deviation that accounts for the reduced dose from the deeper surface, i.e., by weighting the Root stratum and Excavation DCGL,* values' o The values used in the following equations (SOFmcm and osor) can be found in the tables from Section 2b and Section 7a.

LSA-10-07 is located in the southern half of the Burial Pit Open Land Area. The area that comprises the footprint of LSA-10-07 was used to bury radioactive and chemical wastes during the operational lifetime of the Hematite Fuel Fabrication Facility. Documented burial pits, under the governance of the Atomic Energy Commission's regulations, were generated between 1965 and 1970. Also, undocumented waste burials were thought to have occurred pre-1965.

l. Summarize daily work activities on the log sheets provided in Appendix P-6. Provide a description of site conditions (including the condition of isolation controls), samples collected and the status of gamma walkover surveys for every shift that involves work in this survey unit. In the event that a situation arises where the survey instructions cannot be followed as written, stop work and contact Radiological Engineering for resolution. All changes to the survey instructions shall be approved by the RSO before continuing work and be documented in the FSS Field Log.
2. In accordance with HDP-PR-FSS-701, Final Status Survey Plan Development (Sec. 8.4.2), documentation of activities performed, equipment used, potential safety hazards that may be encountered during the performance of characterization activities (along with associated controls) will be documented using the FSS Daily Task Briefing log sheet.
3. A gamma walkover survey (GWS) will be performed using a 2"x2" NaI (Tl) detector held as close to the surface being surveyed as possible (nominally not to exceed l-in. distance from the surface). The meter will be moved in a serpentine pattern at a speed of approximately I foot per second or less. The gamma walkover survey will cover the percentage of the accessible surface areas within the area of interest as indicated in the table above. Notiff Radiological Engineering of any areas, conditions or constraints where surveying (or subsequent sampling) may not be possible. Document the conditions and any resolutions in the FSS Field Log.
4. A GPS system and data logger should be interfaced with the meter. The downloaded information will then be used to prepare maps illustrating relative count rates and to perform statistical analysis of the data. If a GPS data logging system is not available, contact Radiological Engineering to determine specific instructions for performing and documenting gamma walkover surveys.

Each sample location will be selected systematically and have associated GPS coordinates specified. In the case of inaccessible sampling locations additional pairs of random sample coordinates may be generated with the Radiological Engineering's approval in order to identifo an acceptable sampling location.

A map of the survey unit showing predetermined sample locations with associated GPS coordinates will be generated. A copy of the sample map and survey locations will be attached to the survey instruction.

Verifu that isolation controls established in accordance with HDP-PR-HP-602 are in place prior to the start of FSS.

Ensure isolation controls include, as necessary, the use of "waddles", a berm, or trenching to minimize the potential for contaminated soils and water from surrounding areas to cross the boundary of this unit.

Perform daily pre and post QC source checks in accordance with HDP-PR-HP-4 16.

At each systematic soil sampling location a composite soil sample will be collected from each location and depth as determined after the completion of excavation (and will be provided in Appendix P-4). The systematic sample locations will include I (one) samples taken at a depth of 0 - 15 cm (surface) and 5 (five) samples collected at a depth of l5 cm - 1.5 m (root) and 7 (seven) samples collected at a depth of l.5 m to l.65 m (deep).

Biased soil sampling locations may be determined at the discretion of the HP Technician during the performance of the GWS. Biased soil sampling locations may also be determined at the discretion of Radiological Engineering based on statistical analysis of the survey/sampling data or process/historical knowledge of the area. Biased soil samples will be collected in a manner similar to systematic soil sampling locations. Radiological Engineer and/or the HP Technician will log the reason for collection of biased samples in the Field Log sheet and record the location of biased samples on Appendix P-4 of this survey instruction.

NOTE: If trash, waste, or other non-native materials are observed during sample collection, stop sampling activities and notify HP Supervision (or Radiological Engineering) before collecting samples at any sample location in the unit.

All samples collected as part of this survey will be analyzed at an off-site laboratory by gamma spectroscopy for uranium and gamma emitting radionuclides and for Tc-99 by liquid scintillation counting or ICPMS.

Specific Instructions:

NOTE: Unless otherwise indicated, the performance of these specific instructions is the responsibility of the HP Technician.

Before Beginning Work

l. Rad. Engineer/IlP Technician: Veriff, each shift, that isolation controls, established in accordance with HDP-PR-HP-602, are in place prior to the start of FSS using the Daily Task Briefing log sheet.

NOTE: LSA-I 0-07 is bordered to the West by LSA I 4, to the South by LSA-09-01, to the North by LSA 05 and LSA-I 0-06, and to the East by LSA-I 0- l0 and LSA I I. There are no burial pit areas being excavated directly adjacent to LSA-10-07 however; a physical barrier will be in place to minimize the potential for cross contamination from the surrounding LSAs with the exception of the shared boundary of LSA-10-07 and LSA 06.

2. Rad. Engineering/HP Technician: Walk the area looking specifically for any debris material (e.g. asphalt, plastic, concrete, etc...) that may indicate further remediation effons are necessary.
3. Rad. Engineer/IlP Technician: Perform a daily task-specific briefing; documenting the attendants, planned work activities, anticipated hazards, and controls on the FSS Daily Task Briefing log sheet.

NOTE: If soil sampling to a depth greater than one foot is required, ensure HDP Safety & Health are aware of the activity, an Excavation Permit (Form HDP-PR-EHS-021-l) has been performed for the work area, and underground utilities have been identified and marked.

l. Establish a general area background, in accordance with HDP-PR-FSS-711.
2. Perform a gamma walkover of the survey unit holding the probe as close to the surface as possible, in accordance with HDP-PR-FSS-71l.
a. Look and/or listen for locations that exhibit anomalous readings (e.g., count rates in excess of the area background count rate and/or count rates that exceed the IAL for this unit).
b. Mark the location(s) exhibiting anomalous readings to facilitate possible future investigations (for example, use a flag, stake, or other marking resistant to anticipated environmental conditions).
3. At each location where anomalous readings occur, perform a more detailed point survey of the area. Pause and place the survey probe as close as possible to the surface to define and record the total count rate associated with the area of interest on the Field Log.

NOTE: If field conditions limit the ability to perform contact readings, collect readings as close as practical.

Contact HP Supervisor (or Radiological Engineering) regarding the issue for each location. The FIP Technician, HP Supervisor and/or Radiological Engineer will log the issue (and resolution) for each location in the FSS Field Log and on applicable HDP survey forms.

4. GPS (and associated data logger) is the preferred method for performing GWS.

When a GPS and data logger is used, down load and provide the survey data to a GIS Specialist.

a. GIS Specialist: Provide colorimetric maps indicating survey coverage and measurements exceeding the IAL and send the survey data to Radiological Engineering.
b. Radiological Engineering: Provide statistical analysis to determine population characteristics of the survey data set and identifu any areas requiring additional surveys or sampling. Contact HP Technician to mark additional locations requiring survey or sampling as described above in Step 5 of these Specific Instructions.

If a GPS and data logger cannot be used to perform GWS in any portion of this survey unit, the HP Technician will contact Radiological Engineering to determine compensatory survey methods. Radiological Engineering will log the compensatory methods in the FSS Survey Log.

Download the survey data at the end of each shift. To minimize data loss, periodically save the GWS data set throughout the shift.

Sampling

l. Collect soil samples in accordance with HDP-PR-FSS-71 I at locations identified in Appendix P-4. Note that additional biased sampling locations may also be listed as determined by the GWS or as determined by Radiological Engineering.
2. Collect one duplicate sample for every 20 samples. A minimum of one duplicate sample is required for each survey unit.
3. Care should be exercised to ensure the entire sample is included from within the depths specified for sampling.

When collecting the composite samples, vegetation and native debris/rocks with a diameter greater than I inch should be discarded.

NOTE: If a discrete source of radiation (e.g., a fuel pellet) is discovered during the performance of sampling activities, contact HP Supervision or Radiological Engineering. Pause any additional characterization work in the immediate area and use a plastic bag to contain the material. Label the plastic bag per HDP-PR-HP-201, Section 8.2 "Labeling Radioactive Material" and ffansfer the material from the survey unit for controlled storage in the Building 230 Sample Cage via physical turnover to the shift Sample Custodian.

4. Monitor the count rates observed at all accessible surfaces within close proximity (e.g., 2 meter diameter) of each Quality Record Westinghouse Non-Proprietary Class 3
