All;
It is my understanding that we are waiting on a work plan proposal from Daryl for some additional site characterization work in order to evaluate whether a "Contained-Out" (CO) determination is
appropriate for the disposal of source material still present at the site. If so, off-site disposal costs for a non-hazardous waste would be a significant cost savings rather than having to dispose of it as a
hazardous waste at a properly permitted landfill facility. Once I receive the work plan, and the Division has approved the work, then the next phase would be the field work and submitting a report that
documented the findings. An application for the CO determination could also be submitted with the upcoming investigation report if your consultant recommends that path forward based on the
contaminant concentrations and the "sludge" versus "soils" issue previously discussed in the December 2nd email I sent out to the group.
After this additional site characterization work has been completed, then any residual contamination at the property would need to be evaluated for the need to conduct cleanup at the site before any
future site redevelopment takes place. If cleanup actions are needed at the site, then prior to conducting any on-site remediation activities, we would also need to review and approve of a Corrective
Action Plan which would outline your proposed cleanup approach. An example of the contents for a proposed cleanup plan can be found here: https://documents.deq.utah.gov/waste-management-and-
radiation-control/corrective-action/DSHW-2019-016485.pdf
Here is the link to the Contained-Out document which explains the determination process our Division uses in case you need it again: https://documents.deq.utah.gov/waste-management-and-radiation-
control/hazardous-waste/DSHW-2020-015943.pdf
In addition, my supervisor Brad Maulding has retired and has been replaced by Paige Walton, who is cc'd on this. Feel free to reach out to me or to Paige if we can be of any further assistance in
moving this project forward in a timely manner.
Best regards.

Dale/Daryl,
Hope you all had a wonderful Holiday Season.
I wanted to follow up on this to see if there was anything needed on the Stokes Stevenson end. I want to be sure nothing falls through the cracks on our side and we would like to get an update on the
status of this as well. Feel free to reach out to me anytime if you need anything from us.
Happy New Year.
