A.4 Problem Defmition/Background In September 2014, DOE and NYSERDAjointly initiated an aerial radiological survey to examine theradiological conditions of the Western New York Nuclear Service Center (WNYNSC) and adjacent areas, as well as Cattaraugus Creek from the WNYNSC to Lake Erie in Western New York. This survey was conducted by the National Nuclear Security Administration's (NNSA)

Remote Sensing Laboratory (RSL).

The 2014 aerial radiation survey shows five limited areas outside the WNYNSC property with radiation levels that are slightly above the "background" radiation levels seen throughout Western New York. Two of these areas were identified during previous aerial surveys, and the three other locations were only identified during the 2014 aerial survey. The identification of the three new areas is likely due to either: (i) the fact that the areas were not examined during the earlier surveys; (ii) improvements in instrument sensitivity since the time of the earlier surveys, and/or deposition Page 2 of21

Quality Assurance Project Plan NYSE RDA - Field Sampling and Dose Assessment of additional contamination.

The purpose of this project is to collect additional information on radionuclide concentrations in the soil to verify whether the five areas identified as having elevated radiation in the 2014 survey are confirmed to have elevated levels of radionuclides in the soil. If the radionuclide levels in the soil are elevated, a dose assessment will be conducted to confirm that there is no health and safety concern (see Field Sampling and Dose Assessment Plan for the WNYNSC, Section 1, Background and Introduction, and 2, Project Objectives for detail).

Areas of elevated soil concentration levels identified in the 2014 aerial survey results will be verified through the following sampling and survey activities:

• Determining area and regional background soil concentrations of Cs-13 7 and other radionuclides of interest.

• Perform walk-over radiological surveys of the elevated locations identified to qualitatively identify above background readings and variability within the survey unit. Locations with elevated radiation readings will be selected for soil sample collection.

• Use radiation exposure readings and soil sample analysis results to perform radiation dose assessments and determine maximum credible radiation exposures to members of the public

• using credible exposure pathways specific to the general area.

• Compare calculated exposures to '!PPlicable regulatory standards to identify public health and safety issues.

A.5 Project/Task Description The FSDP describes work to be performed, products to be delivered, and the schedule for

• implementation and completion of survey and exposure assessment activities. Section 7 of the FSDP depicts the geographic locations of field tasks and gives an overall picture of how the project will address the project objectives described in Section A.4.

Quality Assurance Project Plan NYSERDA- Field Sampling and Dose Assessment Critical measurements and activities required to meet the project Objectives include:

• GPS or alternative location identification measurements to identify survey areas and sample locations

• MicoRem instrument readings

• Soil depth measurements

• • Soil/sediment sampling, handling, and shipping

• Field documentation and record keeping

• Data verification, validation, and assessment

• Dose assessment methodology and code validation To assure measurements are collected accurately, field staff will be familiar with the FSDP, QAPP, and project specific procedures/field guides developed for each measurement type. Field staff will be trained to the FSDP, QAPP, Health and Safety Plan (HASP), and project specific procedures/field guides prior to initiation of field activities.

A.6 Data Quality Objectives & Indicators A.6.1 Data Quality Objectives (DQO)

This soil sampling and dose assessment study will be completed in accordance with the FSDP and this QAPP. Within the context of the Environmental Protection Agency's guidance for identifying data quality objectives (EPA QA/G-4 Guidance for the Data Quality Objectives Process, 2000), the rationale for the sampling approach is as follows:

1. State the problem - This soil and dose assessment effort is being performed as a follow up activity to the 2014 Aerial Survey of the WNYNSC. Specifically, the 2014 Aerial Survey identified five areas potentially having elevated levels of radioactivity above background. An aerial radiation survey does not, however, provide the data to confirm that all of the areas

.identified are below public health and safety standar4s, for example the criteria in 10 CFR 20.1402, Radiological Criteria for Unrestricted Use.

2. Identify the goals of the study - The key goal for this activity is to evaluate each of the five areas to determine if these areas do in fact contain elevated radionuclide concentrations in the soils, and for those with elevated concentrations, to complete a dose assessment that evaluates the current and future land use information to determine ifthere are any health and safety issues for the property.

The criteria used to evaluate each area are the NRC Radiological Criteria for Unrestricted Use (10 CFR 20.1402), which establishes the requirements that exposure for the public must be less than 25 millirem per year for license termination with unrestricted use.

3. Identify the inputs to the decision - The input to the decision of whether the decision criteria were met include:

Page 5 of21

Quality Assurance Project Plan NYSERDA - Field Sampling and Dose Assessment

• The dose rate data collected during the 2014 Aerial Survey,

• The field dose rate measurements collected for each area,

• The soil samples collected and analyzed for specific alpha, beta and gamma-emitting radionuclides,

• A comparison to the WVDP Phase l Decommissioning Plan Derived Concentration Guidelines

• A dose assessment completed for the current land use, and

• A conservative Resident Fan:ner land use dose assessment.

4. Define the boundaries of the study - The study is focused on five areas identified through the aerial radiation survey, and land use information. *

5. Develop a the analytic approach - If the soil sampling data for cesium, gross alpha or gross beta are greater than 2 standard deviations above background, then a dose assessment will be conducted.

• If the dose assessment information from the various evaluation methods are below 25 mrem/year, then the 10 CFR 20.1402 criteria used for comparison purposes are met.

6. Specify performance or acceptance criteria - Acceptance criteria developed for the aerial survey data are discussed in Section 3 .1. The acceptance criteria developed for the field and soil sampling data are listed below.

Field Survey and Soil Sampling Data Acceptance Criteria The field survey and soil sampling acceptance criteria identified in the plan include:

a) Use of certified standards (e.g., National Institute of Standards and Technology) to calibrate and daily evaluate the operability of instrumentation. The acceptance criteria for the

• instrumentation is specified in the applicable quality assurance documents for the field and laboratory instrumentation.

b) Quality control standards to ensure that the laboratory instrumentation maintained calibration during the sample analysis period. The frequency and acceptance criteria for the laboratory analyses is specified in the GEL Quality Assurance Plan, Rev. 29.

c) Field and laboratory duplicates will be collected and analyzed at a frequency of 20% to ensure that the soil sampling and laboratory analysis methodologies were consistent with the quality control parameters defined by the laboratory.

d) Multiple sample locations and soil depths sent for analysis to ensure that the soil concentration data was representative of the area

7. Optimizing the design for obtaining* data - In order to optimize the design and obtain survey data that addresses the goal of this effort, sampling will be conducted using multiple survey Page 6 of21

Quality Assurance Project Plan NYSERDA- Field Sampling and Dose Assessment methods and data collection efforts in order to compare the dose values calculated for each area. These multiple survey and data collection efforts include:

a) Aerial radiation survey data of the entire area identified the five locations where follow up activities were warranted.

b) Follow up gamma walkovers and tissue equivalent surveys for each area to determine if any elevated locations were within an area, and the dose rates at each location.

c) If any elevated locations are identified they will be sampled and the remainder of the random sampling conducted based on the size of the areas. Soil samples will be collected from 0-100 cm, with at least two at depth samples collected from each area.

d) All surface soil samples will be sent for gross alpha, gross beta and gamma spectroscopy.

e) Next depth interval soil sample analys~s will be co,mpleted if the initial surface analysis was greater than background mean plus 2 standard deviations.

f) Detailed radionuclide analysis will be completed for a minimum of 20% of each area.

g) Finally, dose assessments will be conducted for all areas with dose rate readings or soil sample results greater than 2 standard deviations above background. These assessments were compared to the IO CFR20. l 402 dose standard (25 mrem/year).

A.6.2 Data Quality Indicators (DQI)

As part of systematic planning, measurement performance criteria for DQis are be established and documented for each data collection effort. DQis apply to both laboratory and field activities and include precision, accuracy, representativeness, comparability, and completeness (PARCC).

The following presents a list of the PARCC parameters for this project. Field instrumentation quality records will be documented and evaluated through:

• calibration certifications,

• daily source check logs and periodic field performance checks Page7of21

Field Precision is assessed through the collection and analysis of field duplicates. Analytical Precision is estimated by duplicate/replicate analyses, usually on laboratory control samples, spiked samples and/or field samples. The most commonly used estimates of precision are the relative standard deviation (RSD) and, when only two samples are available, the relative percent difference (RPD).

where Xi is the original sample concentration x 2 is the duplicate sample concentration Page 8 of21

Quality Assurance Project Plan NYSERDA - Field Sampling and Dose Assessment RPDs < 20% will be deemed acceptable for field duplicates and < 10% for laboratory duplicates.

During this project, the following quality control samples will be collected:

• Field duplicate soil samples will be collected from each survey area identified in Figures 1 and 2 of the FSDP. The duplicates will be taken from the 0 -5 cm depth at each sampling location.

Samples will be evaluated for indicator parameters (gross alpha/beta and gamma scan).

• Equipment rinsate blank samples will be collected by each sampling team at the end of each sampling day. Sampling equipment will be cleaned and then rinsed with DI water. A sample of the rinsate will be evaluated for indicator parameters (gross alpha/beta and gamma scan) and found to be less than MDA.

A.6.1.2 Accuracy Accuracy is the closeness of a measured result to an accepted reference value. Accuracy is usually measured as a percent recovery. QC analyses used to measure accuracy in the analytical laboratory include standard recoveries, laboratory control samples, spiked samples, and surrogates, During this project, laboratory accuracy will be evaluated through standard daily QNQC tests performed for each analytic test/method required for project samples by GEL Laboratories.

Typically, instrument control measurements and indicator parameter determination for duplicates and matrix spikes will be performed.

Field instrument accuracy will be evaluated through daily source checks with responses being within+/- 20% of the calibration standard count rate ..

A.6.1.3 Representativeness Sample representativeness is the extent to which measurements actually depict the true environmental condition or population that you are evaluating. It is dependent on the proper design of the sampling program and will be satisfied by ensuring the approved plans were followed during sampling and analysis.

During this project, field staff will be required to accurately determine soil depth, and identify soil type and location micro-topography. These parameters will provide information for evaluation of the representativeness of soil concentration results with other SAs and locations.

A.6.1.4 Comparability Comparability expresses the degree of confidence with which one data set can be compared to another. It is dependent upon the proper design of the sampling program and will be satisfied by ensuring that the approved plans are followed and that proper sampling and analysis techniques are applied. Further, when assessing comparability, data sets should be of known and documented quality.

Page 9 of21

Quality Assurance Project Plan NYSE RDA - Field Sampling and Dose Assessment During the project, because dose assessment scenarios can only be applied to locations compatible with dose scenario assumptions and location uses, comparability will be evaluated through duplicates, along with review of field sampling documentation oflocation specific physical parameters.

A.6.1.5 Completeness Completeness is a measure of the amount of valid data collected compared to the amount planned.

Measurements are considered to be valid if they are unqualified or qualified as estimated data during validation.

During the project, field completeness will be evaluated through comparison of the number of samples collected versus the number of samples planned. Laboratory completeness will be evaluated through comparison of the number of valid measurements to the total number of measurements planned.

Based on the project objectives, a 95% completeness factor will be required for field sample collection. Some latitude is given for samples collected verses those planned to account for possible inaccessibility oflocations or soil types that do not allow for adequate volume, or the inability to achieve desired sample depths due to sampling tool r~fusal. Data results will require a

• 90% completeness rate. Since survey area gamma readings will be automatically collected and field conditions such as terrain and vegetation are unknown, it is reasonable to assume some data may not be acquired due to location and satellite accessibility. In addition, soil sample results may be below target minimum detectable activity (MDA) or laboratory quality objectives may be missed.

A.6.1.6 Bias Bias is the systematic or persistent distortion of a measurement process that causes error in one direction (e.g., the sample measurement is consistently lower than the sample's true value). Bias can be introduced during sampling, analysis, and data evaluation.

During-the project, sampling bias will be addressed through the proper selection and use of sampling tools, and adherence to sampling procedures that limit the loss or gain of constituents to the sample media. Analytical bias refers to deviation in one direction (i.e., high, low or unknown) of the measured value from a known spiked amount. During the project, analytical bias will be evaluated by GEL Laboratories through their analytical QC program.

A.6.1.8 Repeatability Repeatability is a quantitative indicator that is used within a single laboratory (i.e., intralaboratory precision). It is determined when the laboratory, analyst, test method and equipment remain constant and random aliquots of the same sample are analyzed within a short period of time. GEL Laboratories participates in intralaboratory comparison programs which confirm acceptable Page 10 of21

Quality Assurance Project Plan NYSERDA- Field Sampling and Dose Assessment repeatability.

A.6.1.9 Sensitivity Sensitivity is an instruments or methods minimum concentration that can be reliably measured or reported. The laboratory MDAs for each analysis required has been provided and is listed in the FSDP. Daily laboratory QA/QC samples and tests performed by GEL Laboratories will verify MDAs for each sample batch counted. Minimum detectable count rate (MDCR) and MDC for Cs-137 in soil using project field survey instrumentation will not be determined because the data are non-critical and are being collected to identify relative changes in area radiation levels without correlation to soil concentration.

A.7 Special Training/Certification Project personnel will be briefed on the Field Sampling Plan (FSDP), the project Health and Safety Plan, and project specific procedures and protocols. No specialized training will be necessary.

A.8 Documents and Records Documents used or generated during the course of the project will be controlled and will become part of the project files upon completion of the project. Original records (hardcopy and electronic) will be transferred to NYSERDA.

Table A.8.1 shows the project records that will be generated and included in the file.

A.8.2 Laboratory Data In addition to the documentation requirements listed in Table A.8.1, GEL will also be responsible for providing analytical reports to MJWTS. These analytical reports must contain all information required to verify and validate the analytical results that are the subject of each report. The laboratory will be required to provide control charts, analytical methods, method validation reports, and performance evaluation sample results~ All analytical results will undergo Level IV data validation by the Project Data Validation Specialist as described in Section D.

SECTION B- DATA GENERATION & ACQUISITION B.1 Sampling Process Design The sampling processes presented in the FSDP are designed to meet the project objectives discussed in Section A.6. The following subsections provide details related to sample collection to ensure the data are of known and acceptable quality B.1.1 Walkover Survey The GPS course grid walkover survey 'is described in Section 1O.a of the FSDP. The walkover survey sampling network design and rationale are described in Section 2 of the FSDP and is focused on providing information for confirming (or not confirming) the areas identified as having elevated radiation levels in the 2014 aerial survey. A dose assessment will be conducted and the results compared to the dose limits in 10 CFR 20.1401 - Radiological Criteria for Unrestricted Use.. * *

• Walkover surveys wilfbe performed in SA as defined in Table 1 of the FSDP in addition to On Center locations on the Western New York Nuclear Service Center (WNYNSC) and at background areas on the Cattaraugus Territory of the Seneca Nation oflndians.

For each Area, a course grid walkover survey {typically 20 to 30 meter sp~cing) will be conducted utilizing a 2" x 2" Nal gamma detector, coupled with a Ludlum 2241-2 scaler/ratemeter. The count rate signal from the Ludlum 2241-2 will be transferred to a OPS instrument, which will simultaneously log the GPS location and count rate. The logged data will be transferred to a.

computer to be displayed on a map and./or satellite image. After the GPS survey results are completed, they will be reviewed to determine if there are elevated locations above background.

Elevated locations will be sampled as described in Section B.1.2 and static direct radiation levels will be collected.
