__ _ Basis for initial classification:

Review of operational history and interviews conducted during Initial Historical Site Assessment (HSA) showed no historical operational functions or historical storage functions.

Environmental samples from Initial HSA showed no environmental contaminants downstream of the land requiring remediation. Summary of processes and incidents from Historical Site Assessment:

No operational processes performed.

Leased farmland only. No incidents noted from Initial HSA. Summary of Current Radiological Condition:

No current Radioactive Material Areas, Radiologically Controlled Areas, or known radiological conditions and no historical evidence of such. Data Ouality Objectives:

1. State the Problern:

Perform characterization inspections and surveys of sufficient quality and quantity to determine the nature and extent of radioactive contamination in the survey unit in order to validate the classification of " non-impacted" as defined by NUREG-1575 (MARSSIM).

2. Identify the Decision:

Perform radiological survey s in the survey unit to identify the potential presence of plant-related radionuclides at concentrations greater than the minimum detectable concentration (MDC) of the instruments(s) used and greater than the expected naturally-occurring background activity concentrations. 3. Identify Inputs: a. Can the objectives of the characterization survey be achieved with reasonable confidence based on existing data? (If " Yes" , then document the basis for the acceptability of the data.)

""""'02""----Basis for initial classification:

Review of operational history and interviews conducted during Initial Historical Site Assessment (HSA) showed no historical operational functions or historical storage functions. Environmental samples from Initial HSA showed no environmental contaminants downstream of the land requiring remediation. Summary of processes and incidents from Historical Site Assessment:

No operational processes performed. Leased farmland only. No incidents noted from Initial HSA. Summary of Current Radiological Condition:

No current Radioactive Material Areas , Radiologically Controlled Areas, or known radiological conditions and no historical evidence of such. Data Ouality Objectives:

1. State the Problem: Perform characterization inspections and surveys of sufficient quality and quantity to determine the nature and extent of radioactive contamination in the survey unit in order to validate the classification of "non-impacted" as defined b y NUREG-1575 (MARSSIM). 2. Identify the Decision:

Perform radiological surveys in the survey unit to identify the potential presence of plant-related radionuclides at concentrations greater than the minimum detectable concentration (MDC) of the instruments(s) used and greater than the expected naturally-occurring background activity concentrations.

3. Identify lnputs: a. Can the objectives of the characteri z ation survey be achieved with reasonable confidence based on e x isting <lata? (If " Yes", then document the basis for the acceptability of the <lata.) Basis: 5 F C-SRRS -2b.1 17 Yes D No~

FCS Partial Site Release Sample Preparation Guidelines FCS PSR Unit 1 Revision 0 These guidelines are to ensure that sarnples for Partial Site Release are prepared uniformly for onsite gamma spectroscopy analysis.

All preparation methods for off-site sarnples will be determined and validated by the vendor laboratory.

These guidelines were developed with MARLAP considerations, Fort Calhoun Radiological Engineer and other subject matter expert guidance, and general laboratory practices.

For each sample, the following items should be completed prior to gamma spectroscopy counting:

1. Remove soil sarnple from sarnple container.

2. Remove rocks, gravel , and organic material from the soil sample, as best as is possible. NOTE: Sample may be placed in a clean bucket at this time to aid in removal of excess moisture prior to oven drying methods. 3. Transfer sample to drying pan(s). 4. Place drying pan(s) in the drying oven, preheated to approximately 100° C. PRECAUTION:

Sample and drying pan will be hot while oven drying is occurring.

Use care when testing the dryness of the sample. 5. Dry sample until the sample is dry to the touch. Drying times will vary depending on existing moisture content and thickness of sample within drying pan. 6. Remove the sample from the drying oven using appropriate PPE to avoid heat injury and place the sample on heat appropriate surface to cool. 7. Once cooled, retum the sample to an appropriate container for further analysis (i.e. -mass determination, gamma spectroscopy, etc.).
