1. Section uA" begins at the north side of the Pentolite Road overpass and runs to the north side of the Clark Road overpass.
2. Use the coordinate system (Page 4) and sample map example (Page 5) to establish the sample point locations.
3. Begin by marking the starting point (010) at the center line of the stream directly below the north side of the Pentolite Road overpass. This point is 10 feet north of the culvert array and at the centerline of the stream bed.

The first sample point (A-1) is located at the 0/0 coordinate.

4. Measure and mark the other sample points using the dimensions listed on Pages 4 and 5. The odd sample points shall be located at the centerline (X) of the stream bed and be spaced 50 feet apart. The even sample points (Y) shall be located directly between the centerline sample points and at :!:. 7 feet from the centerline (X).
5. If any of the.:!:. 7 feet (Y) sample points fall outside of the stream bed, move the sample point until the location is clearly within the boundary of the stream bed. Note the change in location on a Survey Request Continuation Sheet.

Surface/Subsurface Soil Sampling

1. Observe the "Prerequisites and Special Instructions" on Page 2 of this SR.
2. Locate the sample point identified on Page 4 of this SR.
3. Collect a surface sample in accordance with Section 4.2.2 of PBRF procedure CS-01, USurvey Methodology to Support PBRF License Termination".
4. After the surface sample has been obtained, collect subsurface samples at depths of 6 to 15 inches and 15 to 24 inches in accordance with Step 4.2.6.5 of procedure CS-01.
5. Label each sample in accordance with Step 4.2.1.3 of procedure CS-01 and include the sample point number (e.g., A-1, A-2, etc.) and sample depth (e.g., 0-6",6-15", or 15-24").

NOTE: If excessive rock or other obstructions are encountered prior to achieving a depth of 15 inches, the FSS/Characterization Technician may relocate the sample point up to 3 feet in any direction provided the point remains within the stream bed. Relocation of a sample point greater than 3 feet must be authorized by the FSS/Characterization Supervisor. I NOTE: If rejection occurs prior to reaching the 24 inch mark but after achieving a depth of 15 inches, the samples for that location will be accepted and documented. Form CS-D1/2 Rev 0 Page 3 at6

SUMMARY

Background:

Survey Request #5 is the first of eight (8) SRs generated to perform characterization of the Plum Brook stream bed from Pentolite Road to the overpass of Route 250 (Mitan Rd.) in order to determine the impact from PBRF licensed activities. The stream is divided into four sections designated as Sections A, B, C, and D to facilitate the survey process. This is the first part of a two phase survey. Phase 1 requires the collection of random (non-biased) samples. Phase 2 will incorporate scanning the banks of the stream in order to locate areas of elevated activity from which additional samples may be obtained. Prior surveys of the stream bed indicated the presence of residual activity at various locations. The first 4 SRs, (5,6, 7, and 8) address random sampling of the stream bed and adjoining banks based on a triangular grid pattern in each of the four sections. SRs 9,10, 11, and 12 allow for the collection of biased samples based on scanning activities along the banks of the stream. The purpose of this Survey Request was to collect random samples in the first section of the stream. Identified as Section "A", it is 1,425 in length and encompasses approximately 22,800 sq. feet. Number and types of surveys: SR-5 required a systematic random sampling of sediment in and around the stream bed. A triangular grid pattern was established to facilitate the collection of samples at 0 to 6, 6 to 15, and 15 to 24 inch increments at each of the identified locations. Sample points were distributed at 25 foot intervals along the stream, alternating between the centerline and the two side banks of the stream. Summary of Sample Results. A total of 180 samples were obtained under this SR. Of those samples, 142 indicated the presence of Cs-137 and 25 were identified as containing Co-60. The maximum concentration of Cs-137 was 38.3 pCi/g at sample point 46 in the 15" to 24" depth. Surface activity at that same sample point was 2.9 pCi/g, and the 6"-24" depth contained a concentration of 5.5 pCi/g. Sample point 46 also contained the highest Co-60 activity in the 15" - 24" segment at a concentration of .44 pCi/g. The average concentration of Cs-137 for Section A was 1.64 pCi/g, and the average concentration of Co-60 was 0.12 pCi/g. Four samples exceeded the DCGL of 11.71 pCi/g for Cs-137. They were sample points # 45 (6"-15"), # 46 (15"-24"),

  1. 49 (15"-24"), and # 50 (15"-24"). See Table 1 for a complete listing of all sample results.

Summary of Scan and/or Static Measurements: There was no scan or static measurement activities associated with this SR. Page 1 of 2

SUMMARY

(continued) Problems encountered during surveying: There were two major problems encountered during the performance of this SR. The first concerned the type of material available for sampling in and around the stream bed. Within the stream bed itself, the vast majority of available material is rock. Penetration of the rock is extremely difficult, and in areas where the rock could be pulverized, more rock existed below the surface layer. This material does not meet the required sample matrix. As a result, it was frequently necessary to relocate a sample to a point along the stream bank in order to acquire the sample material. The second major problem encountered was the significant amount of debris and obstructions within and around the stream bed. Fallen trees, areas of dense undergrowth, and the build-up of natural and human debris made traversing the bed extremely difficult, and in some places, hazardous. The stream banks are extremely steep, are covered with underbrush and saplings, and as a result limit the access points available for entering the stream itself. Another problem centered on the sampling devices. Three new sediment samplers were purchased with a new type of core catcher made of extremely thin plastic which could not hold the sample material in the collection tube. As a result, the technicians were unable to collect sufficient sample material at the 6"-15" and 15"-24" depths with the devices and therefore used shovels instead. Summary of QC survey and sample results, including corrective actions taken when acceptance criteria are not met. A total of 18 QC samples were obtained under this SR representing 10 % of the total samples collected. All QC samples met the criteria of section 4.5.2.4 procedure CS-01 "Survey Methodology to Support PBRF License J Termination"

== Conclusion:==

This section of the Plum Brook stream bed does not meet the criteria for a non-impacted area and may require remediation prior to Final Status Survey. Based on activity levels, this segment of the Plum Brook should be classified as a Class 1 area. Additional sub-surface sampling to a depth of 36 inches should be performed at locations identified as having activity in the 15" to 24" layer in order to properly characterize the extent of radionuclide distribution in the stream bed. Phase 2 activities may identify additional areas where sub-surface sampling to the 36 " depth should be performed.
