Quick question Marty and Austin:
Someone on the EA staff has raised the question of whether your ownership of the site allows for deeper than 10 feet of excavation without approval from DOE. Is this something you could quickly clarify in a call tomorrow? Thanks! As I still have the Audit open, I think this is fair game for discussion in the framework of the Audit rather than in a publicly noticed meeting.

Here is what Beau and Doug have now agreed to. Is this OK?
RCI HC-1:
Does the below executive summary accurately capture the intent, results, and recommendations of the geoarchaeological report?
Kairos Power, LLC applied to the U.S. Nuclear Regulatory Commission (NRC) for construction permits for the Hermes 1 and Hermes 2 reactor projects in Oak Ridge, Tennessee. The two proposed undertakings would be within the 185-acre site (Project Site) in the Heritage Center Industrial Park of the East Tennessee Technology Park and could disturb up to approximately 138 acres of land that was previously occupied by Buildings K-31 and K-33. These buildings were formerly part of the U.S. Department of Energy Oak Ridge Gaseous Diffusion Plant complex on the Oak Ridge Reservation.
The NRC determined the direct effects Area of Potential Effects (APE) for both undertakings is the 185-acre Project Site. Due to the nature of the Project Site, and through the NRCs NHPA Section 106 Consultation process for Hermes 1, a decision was made to conduct a geoarchaeological reconnaissance survey as part of Identification of Historic Properties (applicable to both undertakings). This survey of the Project Site was performed in August 2023. The report assesses the potential for deeply buried archaeological deposits within the Project Site, determines whether additional archeological investigations were warranted, and provides a recommendation for regulatory findings. The findings from this report will also be used to support the NHPA Section 106 Consultation process for Hermes 2.
The geoarchaeological reconnaissance survey identified extensive prior disturbances related to artificial fill emplacement and construction of spreader footing foundations.
Along the northern peripheries of the Project Site, highly weathered, natural upland soils developed in residuum weathered from limestone were noted and were determined to exhibit low geoarchaeological potential. Other areas were found to contain natural alluvial soils beneath a thin layer of fill and exhibit high geoarchaeological potential.
Examination of soils and geotechnical data logs from 16 previous geotechnical borings revealed artificial fill materials across the Project Site. Fill ranged from 6.4 to 19 feet thick in areas that were previously truncated (i.e., cut areas) during construction of the former K-31/K-33 buildings, and from 8.9 to 20 feet thick in former low-lying areas (fill areas) adjacent to a former stream. Natural soil surfaces beneath the fill that could potentially contain intact archeological deposits were identified only within the fill areas.
All cut areas were found to exhibit low geoarchaeological potential. Based on the current investigations, five geoarchaeological mapping units were identified, each with specific monitoring recommendations.
NRC determined that the proposed project would have no adverse effect to historic properties, as none are known to exist within the direct effects APE. While the current study suggests that certain portions of the Project Site exhibit the necessary conditions for containing deeply buried archeological materials, this does not mean any such sites have been identified or are present. Rather, it only indicates that natural conditions in some areas are conducive to archeological site preservation. Thus, in the absence of any known archeological sites within the Project Site, the geoarchaeological investigations currently support NRCs finding of no adverse effect to historic properties.
However, given the conditions conducive to site preservation in some areas, a detailed
Archeological Resources Monitoring and Unanticipated Discovery Plan was developed.
Through the Hermes 1 Section 106 process, both documents were accepted by consulting Tribes and concurred with by the State Historic Preservation Office (SHPO).
I am working to assemble the final RCI letter to send hopefully later this week. Thank you for working closely with us to get this finalized.

[External_Sender] HC-1 status Hi Peyton, Just following up from last week. I believe we were going to get an updated HC-1 from Doug after he had a chance to review the markup after our call. Is that your understanding?
