Alternatively, ifthe Survey Unit excavation extends into multiple CSMs (e.g. surface, root &
deep), then the DCGL(s) from the most limiting strata can be used with the equations below; OR If the excavation significantly extends into the deep strata, then the alternate approach presented in section 8.2.5 ofHDP-PR-FSS-701 maybe 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 DCGLw values.
The values used in the following equations (SOFmcan and crsoF) can be found in the tables from Section 2b and Section 7a.

voe Pit in LSA I 0-06 Revision 1: 10/15/2013 The survey unit is classified as MARSSJM Class 1. LSA 10-09 is a new survey unit created out of a need to backfill this "low point" in LSA 10-06 to prevent ground water infiltration.
LSA 10-09 is a small excavated pit within the footprint ofLSA 10-06. The foot print of LSA 10-09 covers a small area that was necessary to excavate due to the presence ofVOC contamination. There were no radiological concerns related to the excavation.
FSS was conducted under Revision O of this instruction set. During chemical confirmation sampling, Environmental Personnel informed Radiological Engineering of some plastic and gravel material in the unit. The origin of the plastic and gravel material was discussed with the Environmental Manager and ECC Personnel. It was determine the material was left behind from the excavation of Test Pits that were dug to investigate the location and depth ofVOC contamination. The Test Pits were lined with geo-fabric and backfilled for safety reasons. The Test Pit area was later excavated down to the phreatic surface in accordance with the SAP, however, the elevation of the Test Pits was below the phreatic surface. FSS and confirmation sampling was stopped in this area and excavation activities began in order to remove the gravel and plastic material as well as excavate the material that was used to backfill the Test Pits. Civil survey of the pit was performed to provide evidence that the excavation efforts removed any backfill left in the unit.

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.
- 5.
This is a Class 1 Survey Unit. 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 identify an acceptable sampling location.
- 6.
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.
- 7.
Verify that isolation controls established in accordance with HDP-PR-HP-602 are in place prior to the start ofFSS.
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.
- 8.
Perform daily pre and post QC source checks in accordance with HDP-PR-HP-416.
- 9.
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 3 (three) samples taken at a depth of O - 15 cm (surface) and 6 (six) samples collected at a depth of 15 cm - 1.5 m (root) and 4 (four) samples collected at a depth of 1.5 m to 1.65 m (deep).
- 10. 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: U 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.
- 11. 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
- 1.
Rad. Engineer/HP Technician: Verify each shjft that isolation controls established in accordance with HDP-PR-HP-602 are in place prior to the start ofFSS using the Daily Task Briefing log sheet. LSA 10-09 is bordered on all sides by LSA 10-06. LSA 10-09 is a low point within LSA 10-06 and therefore a physical barrier must be in place to minimize the potential for cross contamination.
- 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 efforts are necessary.
- 3.
Rad. Engineer/HP 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-021-1) has been performed for the work area, Quality Record Westinghouse Non-Proprietary Class 3
Revision: 2 HDP-PR-FSS-701, Final Status Survey Plan Development APPENDIX P-3 FSS SAMPLE INSTRUCTIONS and underground utilities have been identified and marked.
Gamma Walkover Surveys (GWS)
- 1.
Establish a general area background, in accordance with HDP-PR-FSS-711.
Page P-4 of 5
- 2.
Perfonn a gamma walkover of the survey unit holding the probe as close to the surface as possible, in accordance with HDP-PR-FSS-7 I I.
- 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, perfonn 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 HP 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 identify 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 Jog 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 Note: The following instructions provide directions for sampling the floor of the unit. An addendum will be provided with instructions for sampling the sidewalls of the unit.
- 1.
Collect soil samples in accordance with HDP-PR-FSS-7 I 1 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 1 inch should be discarded.
- 4.
Monitor the count rates observed at all accessible surfaces within close proximity ( e.g., 2 meter diameter) of each biased sampling location, as practical. Note any accessibility issues and discuss compensatory measures with Quality Record Westinghouse Non-Proprietary Class 3

voe Pit in LSA 10-06 Addendum to Revision 1: 10/17/2013 The survey unit is classified as MARSSIM Class 1. LSA 10-09 is a new survey unit created out of a need to backfill this "low point" in LSA 10-06 to prevent ground water infiltration.
LSA 10-09 is a small excavated pit within the footprint of LSA 10-06. The foot print of LSA 10-09 covers a small area that was necessary to excavate due to the presence ofVOC contamination. There were no radiological concerns related to the excavation.
The following instructions provide direction on sampling the sidewalls in LSA 10-09.
The surface area from the side walls is as follows:
Surface Area (Sq. Meters) 12.1 12.1 8.8 7.9 12.2 23.6 9.0 The area bounded by the statistical sample population is 30.9 sq. m. The surface area from each side wall is smaller; therefore 7 samples is statistically sufficient as shown in Appendix P-1 of procedure HDP-PR-FSS-701.
