June 2020 CA Progress Report Ms. Kuhn:

In accordance with Item 19 of Consent Agreement (CA) 19-02-HW, this progress report is being submitted to you, including the following requested information:

(a) a brief description of the actions which Westinghouse has taken toward achieving compliance with the Consent Agreement during the previous month; (b) results of sampling and tests, in tabular summary format received by Westinghouse during the reporting period; (c) a brief description of all actions which are scheduled for the next month to achieve compliance with the Consent Agreement, and other information relating to the progress of the work as deemed necessary or requested by the Department; and (d) information regarding the percentage of work completed and any delays encountered or anticipated that may affect the approved schedule for implementation of the terms of the Consent Agreement, and a description of efforts made to mitigate delays or avoid anticipated delays.

In response to the above requirements, the following is being reported to the Department since the last progress report on June 15, 2020:

(a) Actions during the previous month:

Westinghouse began implementation of the Final Remedial Investigation (RI) Work Plan on 6/10/19. To comply with Item 4 of the CA, the following actions were completed this month.

Submitted the East Lagoon Closure Plan in LTR-RAC-20-57 dated June 30, 2020 Continued preparing the report for the Tc-99 Source Investigation Work Plan Results - Phase I and Phase II Completed the following activities to support the Southern Storage Area (SSA) Operable Unit (OU) Work Plan:

o Removed and packaged for off-site shipment as low-level radioactive waste (LLRW) 3 intermodal containers from the Southern Storage Area (C-41, C-56, C-60)

Conducted radiological soil surface surveys under all removed containers.

The surface surveys did not indicate the need to remove soil.

Collected soil samples underneath the containers on June 29, 2020. The sampling included bias VOC samples underneath C-56 and C-60 where previous contamination was documented within the intermodal containers.

o Continued wet combustible material (WCM) drum removal from 3 intermodal containers (C-64, C-19, and C-54) that have been on hold. Drums potentially containing perchloroethylene were segregated and stored.

Intermodal container C-64 was safely emptied of its contents on 6/17/2020.

Health physics radiological surveys of the pallets and the sealand flooring indicated no environmental impact.

Intermodal container C-19 was safely emptied of its contents on 6/26/2020.

Health physics radiological surveys of the pallets and the sealand flooring indicated no environmental impact.

Intermodal container C-54, was safely emptied of its contents on 7/1/2020.

Health physics surveys of the pallets indicated no impact to the environment. A subsequent survey of the sealand flooring indicated a small area of impact towards the back, measuring approximately 1-foot in diameter. The impact was quantified at 1,000 dpm/100cm² for alpha contamination.

o Seven (7) of the original eleven (11) intermodal containers with drums potentially containing perchloroethylene have been emptied since April 14, 2020.

(b) Results of sampling and tests:

Tabulated results of Hydrofluoric Acid Spiking Station #1 (HFSS#1) Soil Sampling conducted May 4-6, 2020 are included as Attachment A. The associated laboratory reports are included as Attachment B.

(c) Brief description of all actions which are scheduled for the next month:

In accordance with Item 4 of the CA, Westinghouse will continue to implement the Work Plan to include the following actions:

o Submit Final Interim Remedial Investigation Data Summary Report o Submit the Hydrofluoric Acid Spiking Station #1 (HFSS#1) Soil Sampling Report and associated Technical Basis Document o Submit an assessment report of the Tc-99 Source Investigation Work Plan Results -

Phase I and Phase II o Host a webinar to discuss and propose the scope for the RI Phase II Work Plan o Continue WCM drum removal from the 4 remaining intermodal containers; segregate and store drums potentially containing perchloroethylene o Submit tabulated data from the Southern Storage Area Soil Sampling conducted on June 29, 2020 for intermodal containers C-41, C-56, C-60 (d) Percentage of work completed and any delays encountered or anticipated:

Assessment activities identified in the Final Remedial Investigation Work Plan and associated addendums have been completed, with a summary report submitted.

The samples in this SDG were analyzed on a "dry weight" basis.

Data Summary:

All sample data provided in this report met the acceptance criteria specified in the analytical methods and procedures for initial calibration, continuing calibration, instrument controls and process controls where applicable, with the following exceptions.

Quality Control (QC) Information Matrix Spike (MS)/Post Spike (PS) Recovery Statement The percent recoveries (%R) obtained from the spike analyses are evaluated when the sample concentration is less than four times (4X) the spike concentration added. The matrix spike recovered outside of the established acceptance limits due to matrix interference and/or non-homogeneity.

Dilutions may be required for many reasons, including to minimize matrix interferences or to bring over range target analyte concentrations into the linear calibration range.

Technical Information Sample Dilutions The following samples 1204557905 (HF1-B4-(1-2)DUP), 1204557906 (HF1-B4-(2-4)DUP), 1204557907 (HF1-B4-(1-2)MS), 1204557908 (HF1-B4-(2-4)MS), 510807001 (HF1-B4-(1-2)), 510807002 (HF1-B4-(2-4)),

510807003 (HF1-B4-(4-5.33)), 510807004 (HF1-B5-(1-2)), 510807005 (HF1-B5-(2-4)), 510807006 (HF1-B5-(4-6)), 510807007 (HF1-B5-(6-8)), 510807012 (HF1-B7-(0-2)), 510807013 (HF1-B7-(2-4)) and 510807014 (HF1-B7-(4-5.42)) were diluted because target analyte concentrations exceeded the calibration range.

Dilutions may be required for many reasons, including to minimize matrix interferences or to bring over range target analyte concentrations into the linear calibration range.

Sample Analyte Value 1204557617 (HF1-B4-(1-2)DUP) Uranium-235/236 RPD 23.7* (0.00%-20.00%) RER 1.08 (0-3)

Miscellaneous Information Manual Integration Manual integration of alpha spectroscopy spectra 510807014 (HF1-B7-(4-5.42)) was performed to fully separate counts in Regions of Interest which would have been biased.

Additional Comments The tracer peak centroid for sample 510807014 (HF1-B7-(4-5.42)) is greater than 50 keV from the expected library energy value for the tracer; however, the tracer yield requirement was met and the tracer peak is within the tracer region of interest.
