Subject: Radioactive Material License UT 2300249; EPA ID Number UTD982598898 Class 1 Permit Modification Combined Surety – Permanent Removal of equipment from the Mixed Waste Operations Building Dear Mr. Hansen EnergySolutions herein requests a modification of the Clive Facility Combined Surety to remove and dispose of the Microencapsulation Extruder and Crusher and the Kinetic Mixer from the Mixed Waste Operations Building at the Mixed Waste Facility. The equipment being removed is listed in Attachment II-7-2 of the state-issued Part B Permit (Permit) Sections VII.f and VII.g of the Closure Cost Calculations Spreadsheet.
The Microencapsulation Extruder and Crusher and Kinetic Mixer are no longer used in managing waste at the Mixed Waste Facility and haven’t been for several decades. The equipment being removed will make way for additional storage space in the Mixed Waste Operations building to
assist in meeting the recent demands for additional liquids storage. The equipment is currently attached to the concrete and once removed, the fasteners/hold downs will be removed and any damage or penetrations will be sealed with Sikaflex or other equivalent product to ensure
compliance with Attachment II-3; Site Inspection Plan, of the Permit. Section 4.e. Mixed Waste Operations Building Process area- Daily Inspection requires:
i. Visually check the floor surface for coating integrity, cracks in the concrete, or any
other concerns.
The repairs will be made and documented on the Inspection form of CL-MD-PR-211-F1, Mixed
Waste Site Inspections. Inspection forms will be provided to the Division upon request once
completed.
This modification requires a Class 1 modification to revise the summary calculations in Attachment II-7-1; Overall Facility Closure Cost Summary, Attachment II-7-2; Closure Cost Calculations, and Attachment II-7-3; Reserve Capacity Calculations of the state-issued Part B
Permit.
Attached is the revised Sections VII.f and VII.g of the MW Part B Calculations surety calculations spreadsheet highlighting the changes described above (Attachment II-7-2). This
change decreases the Mixed Waste portion of the Combined Surety from $25,387,618.12 to $25,384,188.21 (decrease of $3,429.91). Due to the small change (decrease) and limited risk to

the Division and the public, EnergySolutions requests to incorporate these adjustments at a later date when the next scheduled Annual Surety Update will be due by March 1, 2026.
Should there be any questions regarding this request, please contact me at 801-649-2043.

Formula Development for waste awaiting treatment:Assume that there are 4 waste streams without existing formulas. This is not a compliance point for the surety because wastes
may become designated for treatment or require new formulas due to information generated after a given waste arrives on site (HSWA Analysis).
Quantity limitations for treatment waste are changed according to facility needs as long as overall treatment costs within the surety remain constant in accordance with Attachment II-7.
The maximum quantity of waste at the site, untreated or awaiting disposal (including thermal desorption condensate), shall not exceed 7,500 cubic yards.Waste in storage is inclusive of all waste outside of permitted disposal areas. This limit includes waste that is generated both on site and off site and includes
materials that when declared a waste would become an untreated hazardous waste, such as water within the surface impoundment, decontaminationwater within the 90-day tanks at the wash bay, and laboratory chemicals.

structures around the embankments, and permanent fencing. The final cover design is assumed to be consistent with approved plan drawings of the Groundwater Quality Discharge Permit.
The assumed maximum quantities of stored waste and waste from site reclamation should bring the embankment up to final grade in preparation for construction of the final cover;
no clean fill will be added to achieve the final grade. If the maximum quantities of waste are not on site, and clean fill is needed, the costs associated with the disposal of the assumed
maximum waste volume would more than account for the excavation of clean fill and the reclamation of the clean fill areas. Reclamation of the pits, used for erosion barrier
and filter material, is covered under a bond with the BLM.
Refer to Figures 7C & 7D in the 2024 Engineering Analysisfor premature closure design and cover information.
