Topham, PE ifr DATE: April 27, 2021 SUBJECT: 2021 Engineering Module 73, Inspection of disposal of lle.(2) decommissioning debris from in situ recovery facilities — Disposal Activity March 30, 2021 Authority Radioactive Materials License #UT1900479, Condition 10.5: "In accordance with the Licensee's submittal to the NRC dated May 20, 1993, the Licensee is hereby authorized to dispose of byproduct material generated at licensed in situ leach (ISL) [aka in situ recovery (ISR) facilities, subject to [...] conditions." (Conditions are cited below as Requirements.) R313-12-3 (quoting 10 CFR 40.4): "Byproduct Material means the tailings or wastes produced by the extraction or concentration of uranium or thorium from any ore processed primarily for its source material content, including discrete surface wastes resulting from uranium solution extraction processes."1 10 CFR Part 40 Appendix A, Criterion 2: "To avoid proliferation of small waste disposal sites and thereby reduce perpetual surveillance obligations, byproduct material from in situ extraction operations, such as residues from solution evaporation or contaminated control processes, and wastes from small remote above ground extraction operations must be disposed of at existing large mill tailings disposal sites; unless, considering the nature of the wastes, such as their volume and specific activity, and the costs and environmental impacts of transporting the wastes to a large disposal site, such offsite disposal This definition amends the language given in Section 1le.(2) of the Atomic Energy Act as amended in 1954 to include in situ recovery (or in situ leach) facilities on the same footing as conventional uranium mills. This is done by referencing "solution extraction" in the definition. Text of the Atomic Energy Act as amended in 1954 can be found in NUREG-0980, Volume 1, No. 10.

Requirements 1. Radioactive Materials License #UT1900479, Condition 10.5A: "Disposal of ISL waste is limited to 5,000 cubic yards from a single source." The Division considers a source to be a discrete facility defined by its geographic boundaries.2 2. Radioactive Materials License #UT1900479, Condition 10.5B: "All ISL contaminated equipment shall be dismantled, crushed, or sectioned to minimize void spaces. Barrels containing waste other than soil or sludges shall be emptied into the disposal area and the barrels crushed. Barrels containing soil or sludges shall be verified by the Licensee to be full prior to disposal. Barrels not completely full shall be filled with tailings or soil prior to disposal." 3. Radioactive Materials License #UT1900479, Condition 10.5C: "All ISL waste shall be buried in Cell No. 3 unless prior written approval is obtained from the Director for alternate burial locations." 4. Radioactive Materials License #UT1900479, Condition 10.5D: "All disposal activities shall be documented and records thereof maintained on-site. The documentation shall include descriptions of the ISL waste and the disposal locations, as well as all actions required by this License condition." 5. Radioactive Materials License #UT1900479, Condition 10.5E: "The Licensee shall also submit for Director approval a revised written Standard Operating Procedure (SOP) for ISL disposal on or before December 1, 2010. The revised SOP shall describe the documentation required for ISL disposal, which shall include but is not limited to the following:" (1) The material disposal area must be located on a tailings beach area of the disposal cell or on an area of the cell that is underlain by tailings sands; (2) The elevation of the material disposal area will not exceed the plane or grade of the elevations of the uppermost flexible membrane liner of the tailings cell; (3) Such ISL byproduct material will be segregated from any mill material and equipment disposed of in the cells pursuant to License Condition 10.4, and the ISL byproduct material from each in situ leach source will be segregated from the byproduct material from all other in situ leach sources; (4) Absence of void space inside barrels disposed, including physical verification before disposal; and (5) Detailed engineering drawings which demonstrate: 2 A "source" in this context is a geographically discrete facility. See Letter from Rusty Lundberg to Jo Ann Tischler dated November 7, 2013 (DRC-2013-005682) 2021 ISR Decommissioning Debris Disposal File Inspection Report March 30, 2021 Page 3 a. There are at least 4 feet of tailings sands under the bottom of each disposal area; and b. The bottom of each disposal area is located at least 12 feet from the sides or dikes of the tailings cell. 6. Radioactive Materials License #UT1900479, Condition 10.5F: The Licensee shall notify the Director in writing at least 7 calendar days prior to the proposed scheduled date for disposal of any byproduct material generated at ISL facilities in the tailings cells. An annual summary of the amounts of waste disposed of from off-site ISL generators shall be sent to the Director on or before November 1 of each calendar year. Observations Russell J. Topham, PE of the Utah Division of Waste Management and Radiation Control (the Division), inspected the disposal of two loads of decommissioning debris from the Strata Energy facility near Ross, Wyoming. The material included filters, piping, fittings, and other assorted debris from the in-situ leach uranium recovery facility noted above and was transported in fabric/plastic bags. The material qualifies as lle.(2) byproduct material, and is appropriate for disposal in the Impoundment 3 cap. Upon arrival at the mill, the material was staged near the excavation dedicated for disposal of material from this generator. (see Photos 2, 3 and 5 in the accompanying Photo Log) This inspection focused on the Licensee's implementation of Standard Operating Procedure SOP PBL- 10, which governs disposal of lle.(2) byproduct material from in situ recovery facilities. (pertinent data sheets from PBL-10 used in this inspection are attached) Incoming shipments for all materials are subject to another procedure, SOP PBL-19, which was not the subject of this inspection. The Licensee used revision R-3.4 of SOP PBL-10, dated February 1, 2018 for this disposal event. Revision R-3.4 is the most recent version of the procedure. The Licensee maintains a map of Tailings Impoundment 3 in the Mill office that shows the dedicated disposal location assigned for each 11e.(2) debris generator. Examination of that map reveals that if disposal operations are limited to the lateral extents of the dedicated disposal plots and if the vertical location of placement of material is limited to within two feet below the upper surface of the tailings, as required in the governing procedure, neither the excavation nor the debris will endanger the integrity of the impoundment liner. Lateral disposal pit locations are determined and located in the field by survey prior to excavation. The bottom of the excavations is extended into the tailings sand, and the depth is surveyed prior to placement of material into the excavation. (see Photo 5 in the accompanying photo log) Once the debris is placed in the excavation and compressed, the top of debris is surveyed, after which cover soil is placed and compacted. Lateral locations were checked by the inspector onsite. The examined disposal data packets included survey data that shows that the vertical placement is below the peripheral top of liner and well above the liner beneath the excavation. 2021 ISR Decommissioning Debris Disposal File Inspection Report March 30, 2021 Page 4 SOP PBL-10 requires that material must be accepted for disposal prior to departure of the transport vehicle from the generator. This allows the Licensee to ascertain that the material characteristics meet the requirements for classification as 11e.(2) byproduct material, and to verify that the quantity to be shipped will not exceed the 5,000 cubic yard per source limit established in License Condition 10.5A. Checks of running receipt totals confirmed that the volume limits had not been exceeded. The material is checked upon receipt to verify that what was shipped is what was expected. Once the material is accepted for shipment, the receipt and burial are scheduled and the Licensee sends a seven-day advance notice to the Division of the date scheduled for the burial event and number of loads anticipated for disposal. The Division received the written notice for both loads disposed. Observations Items reviewed during the inspection included: 1. Initiation date for load document packet 2. Generator identification 3. Pre-shipment radiological report 4. Certification of absence of RCRA-listed products (RCRA Certification) 5. Shipper's manifest 6. Bill of Lading 7. Scalehouse weigh ticket 8. 7-Day notice to the Division 9. Equipment release form (used to document decontamination) 10. Disposal event-related surveys The above list is more extensive than one generated from the Requirements section of this report, but reflects the items required in SOP PBL-10. The burial operation commenced after a brief delay as the field crew enlarged the disposal excavation. During the burial, appropriate safety precautions were followed, including field hands and inspectors positioning themselves upwind of the burial to prevent inhalation of dust or contaminants. As detailed in the photos, the material was placed in the excavation following survey of the excavation depth. The top of the material was surveyed once placed in the excavation. The survey data demonstrates that the disposal operation did not impact the impoundment liner. Following the survey, clean fill was placed over the debris to complete the burial. The equipment operator densified the cover soil by wheel walking the loader over the cover soil several times. The surface was not yielding to the weight of the loader when the crew discontinued the operation. Following the disposal operation, the inspector reported his findings to Mr. Garrin Palmer, the highest- ranking member of the management staff available at the time. Conclusions and Recommendations The Licensee appears fully compliant with applicable laws, standards, requirements and License Conditions with respect to disposal of 11e.(2) byproduct material generated as decommissioning debris from in situ uranium recovery facilities during this operation. 2021 ISR Decommissioning Debris Disposal File Inspection Report March 30, 2021 Page 5 The inspection should be closed out.
