Comments:
REVISION 3: 8/15/2013 The Limestone fill Arca #l is a.n open land area located southwest of Building I OJ (also referred to as the Tile Barn). The surface grade within this open land area was raised by placing fill composed of limestone that had been previously used in the ventilation exhaust scrubber system.
During remediation activities in LSA 05-01 it was fou nd limestone had been used to fill a sloped area near State HWY P, which runs adjacent to the survey unit. This area was not immediately remediated due to concerns with removing the material might affect HWY P's support structure. The Missouri Department of Transportation (MoDOT) was notified of this issue, and stated the sloped area near HWY P could be remedialed to a I: I slope and backfi lled with material to a minimum 2: I slope.
While the slope is being rernediated (and until the backfill operation is complete) HOP would be responsible for closing down the left lane (closest to LSA 05-01) of HWY P and provide trafflC control.
H DP will conduct excavation activities of the sloped area of LSA 05-0 l to remove the limestone till present to a I: 1 slope. While the area is excavated and before backfill operations begin, HOP will conduct FSS of the sloped area of LSA 05-0 I. The fo llowing instructions explain how FSS of the sloped area of LSA 05-0 I, including the footprint of Spring Pipe Section #2 will be conducted.
Please note the fo llowing instructions cover the portion of systematic and biased FSS samples and FSS scans that fall within the sloped are11 boundary of LSA 05-0 l. Further instruction is provided for taking the rest of the systematic and biased FSS samples and FSS scans that cover the LS.A 05-0 I survey unit.

Biased samples may be collected during Gamma Walkover Surveys (at the discretion of the HP Technician),
after statistical analysis of the survey data, or at the direction of Radiological Engineering.
Inaccessible (Underwater) Sample Locations:
Samples will be collected at three stations located within areas that will be underwater. Two samples will be collected from each location (for a total of 6 samples). See Appendix P-4 for detail regarding the depth and location of these samples.
Limestone Slope Area: NOTE: The purpose of the following biased samples on the slope are to determine the extent of limestone that extends beyond a 1:1 slope, therefore the following samples may be taken prior to isolation and control or any time prior to backfill.
Both vertical and horizontal cores will be used to collect samples from the sloped area containing limestone.
VERTICAL SAMPLES: Samples will be collected by coring vertically down into the sloped limestone area from 9 stations located on the sloped surface leading up to State Road P. Two samples will be collected from each station for a total of 18 samples.
HORIZONTAL SAMPLES: Samples will be collected by coring horizontally into the sloped limestone area from 5 stations located on the sloped surface near State Road P. Two samples will be collected from each station for a total of 10 coring locations. The first sample will be collected to determine the extent of limestone remaining on the hillside. The second sample will collect the remaining 6-inches of soil past the depth of remaining limestone.
If no limestone is present, sample the first 6-inches of soil; then sample the next 6-inches of soil. See details from the instructions and the maps provided in subsequent sections of this survey instruction.

Revision: 2 Page P-5 of 12 IIDP-PR-FSS-701, Final Status Survey Plan Development APPENDIX P-3 FSS SAMPLE INSTRUCTIONS Biased Sampling: Slope Near Highway P Eigll\\ investigation samples were previously collected from three core sampling locations following the initial excavation on the slope adjacent ro Highway P.
Three samples were collected from the first core sampling location (located closest to LSA 05-02) at depths OS-1.0', l.5'-2.0' and 3.0'-J.5' Tiu-ee samples were c<illected from the second core sampling location (center) at depths l.5'-2.0'. 4.0'-4.5' and 5.0'-5.5'.
Two samples collected from the third sample location (located closest the rn:e stump) at depths I.5'-2.0' and 2.5'-3.0' (refusal at 3.0').
Based on these sample results (documented on Appendix G-2 of HOP-PR-FSS-721, c1llacbed), further sampling is necessary following excavation to adequately show the survey unit is acceptable for unn:stricled release.
Nine additional vertical core sampling location:i have been defined to adequately bound the. area of elevated activity identified by the initial investigation samples, and to provide a defined area fo r ap plying the elevated measurement eoro parison (EMC) evaluation.
lust ructions:
I.
Locate the 9 vertical core sampling locations on the slope near H ighwa)' P located in LSA 05-01 as indicated on the attached map.
- 2. Samples will be taken vertically into the slope (perpendicular to level ground).
- 3. At each of the 9 locarions, 2 samples will be C(illected (which will result in a total of 18 sc1mples).
- a.
The first (top) sample will be a composite sample through the depth of the limestone material remaining on the slope after excavation. Note, if no limestone material remains, a sample will be taken to a depth of 6 inches.
- b.
The second (bonom) sample will be taken of lop 6 inches of soil beneath the limestone or directly below the top 6 inch sample.
- 4.
Locate the 5 horizontal core sampling locations. Collect horizontal core samples through the thickness of limestone maierial re1naining on the slope (approximately parallel to surface grade of the survey unit).
NOTE: These horizontal core sample locations will be defined following the removal of the slope (;Ontaining the limestone to the extent possible, and placed at locations where visual inspection identifies that limesrone remains within the slope.
- 5. Collect the 5 horizontal core samples in the same manner as the 9 ve11ical core samples.
u) The lirst sample will be a composite sample th.rough the extent. of limestone material remaining.
b)
The second sample will he taken of the following 6 inches of material beyond the limestone.
- 6. Docwnent the depth and locc1tion (coordinates) of rhe horizontal wrc samples on the Field Log (Appendix P-6).

Revision: 2 HDP-PR-FSS-701, Fioal Status Survey Plan Development APPENDIX P-3 FSS SAMPLE lNSTRUCTIONS ATTACHMENT t Page P-6 of 12 The following compensatory measures are in response to the inability to conduct an in-situ scan survey in por1ions of the survey unit that are underwater or may hecome submerged under water during the work associated with rt:mediation of this survey unit. These meac;ures have been implemented within portion of the survey unit; and will be implemented within the balance of the survey unit following NRC concurrence.
Ex-situ Scan Surveys: These measurements serve to confinn the absence of gamma-emitting radionuclides in excavated soil at concentrations that exceed the IAL. Based on these measurements, it can be reasonably inferred that any residual concentrations remaining within the excavation would also not. result in a scan survey result that exceeds the LAL. A scan MDC was calculated for saturated soi Is excavated from portions of a survey unit that arc underwater. The scan MDC for saturated soil conditions is greater than the calculated scan MDC, and therefore the lAL remains unchanged. The MDC for these measurements is diminished slightly (approximately IO percent of the efficiency value) due to the extremely saturated condition of the soil. (See subsequent sections in this attachment)
Excavation Depth: Extensive sampling was conducted during the RASS to identify the location and depth of Tc-99 contamination in limestone and in underlying soil. The sampling was conducted by making three core borings with samples obtained al the bot1om of each boring.
Two of the three locations (4525-RA-130304-05-I 2 and 4424-RA-1 302 19-09-05) showed the depth of contarni.nation to extend to less than two feet below the excavation surface al that time.
The third boring (444 I -RA-130220-09-06) showed residual Tc-99 at a concentration that was approximately two times the DCGL at a depth of one foot below the surface of the excavation at that time.
As a part of the design for the piping installation, this information was considered to ensure that the excavation for placement of the piping exceeded the known depth or the contamination. The excavation was completed approximately one foot below the deepest coring., and slightly more than two feet below the sample showing residual Tc-99 at approximately two times the DCGL.
Biased Sampling: In the absence of scan survey dal'a, the basis for selecting t}1e biased sampling locations considers the submerged portions of the survey unit (and therefore cannot be directly scanned) and the locations that will be inaccessible for excavation following piping installation.
in the event that residual radioactivity exceeds the expected concentrations. In the event that residual radioactivity exceeds the expected concentrations the amount of analytical data obtained from the biased sampling locations is expected Lo provide adequate information to support the derivation of an average concentration.
Excavation Depth~ The following table includes the data summary of the samples obtained from core boring, and the subsequent figure ill uslrates the depth of contamination relative to the fina l depth of the excavation.
The core boring ( 444 l-RA-l 30220-09-06) showed resid ua.l Tc-99 at a concentration that was approximately t:wo times the OCGL at a depth of one foot" he low the surface of the excavation at that time, however with the removal of an additional two feet of soil, it is reasonable to expect that residual radioactivity, if any, wil l not exceed the DCGL. This assumption is consistent with reduction in conc.entration with increasing depth exhibited by the sample results contained in the section entitled RAS$ Da.ta iind Figures in the LSA-05-0 I survey instruction package.

Descriptjon:
Spring House Foundation (portion of LSA 05-0 I)
The Limestone Fill Area ff I is an open land area located southwest of Building IO I (also referred to as the Tile 8am). The surface grade within this open land area was raised by placing fill composed of limestone that had been previously used in the ventilation exhaust scrubber system.
During remediation, n concrete foundation was found imbedded in the :;loped portion of LSA 05-0 I. The foundation consists of 3 different sections, a flat (floor) portion that is approximately 8 feet wide, a concrete piece that is perpendicular on one end to the flat portion (left wall) and a third concrete piece perpendicular to the other end of the flat portion (right wall). The foundation will be sampled and surveyed in accordance with the instrnctions in the seer ion below titled Survey and Sampling of Concrete Foundation.
The surveys will be performed in accordance with HDP-PR-I-IP-3 11 and will be compared to the limits found in document Guiddines for Dec;on/umination of Facilities and Equipment Prior 10 Release for Unrestrtcted Use or Termination of licenses for Byproducr. Soun.:e, ur Special Nuclear Material.

The Cistern Bum Pit open land area is located southwest of Building IO I. This feature was created during the agricultural use of this property to collect water for livestock consumption. Circa 1960 - 1974, this was the loca1ion where wooden pallets and other combustible wastes that may have coniained radioactive material were incinerated. Nole tha1 the following two portions of the site are included in the ponion of the site designated as the Cistem Bum Pi1 Area.
The Limestone Fill Area# I is an open land area located st1uthwcst of Building l O I (also referred co as the Tile Barn). The surface grade within this open land area was raised by pl.icing fill composed of limestone that had been previously used in the ventilatio1t exhaust scrubber syslcm. During excavation of the limestone, a 14 inch diame1er perforated PVC: pipe was exposed 1ha1 ran through the center track of the survey unit. This pipe was installed during the time frame the limestone was being placed as fill. The purpose of the pipe was co diver1 the natural spring water thal rW1S through !.he survey unit to the Site Pond. After this pipe was exposed, ii was apparent it was not sufficient to manage the amount of water flowing from the spring into the Unit and 1herefore the Unit was often flooded. Also, results from samples taken where the pipe was located indicated limestone was placed below where the pipe was installed. A new 12 inch diameter perfora1ed PVC pipe was installed to the right of where the original pipe was placed for water managemcn! purposes. The original pipe was removed and properly disposed in order ro excavate the limestone that remained below 1he original pipe.
The Red Room Roof Burial Pit is an open land area located immediately south of Building IOI. The portion of Building 240-1 referred to as the "Red Room" was used for UF6 conversion of highly e,wiched uranium. The roof of the Red Room wa~ removed and buried in thi5 open land aren.
The survey unit is classified as MARSSIM Class I.
