Notice of Public Comment on EnergySolutions’ request for a one time site-specific treatment variance for waste ash with Dioxan-Furan contamination
EnergySolutions LLC
Mixed Waste Facility
EnergySolutions requests a variance from Utah Administrative Code (UAC) R315-268-40(a)(3) to receive and macroencapsulate waste ash from incinerator and metal recycling processes. This
waste stream contains dibenzo-p-dioxin and dibenzofuran underlying hazardous constituents (UHCs) above their respective treatment standards denoted with the Universal Treatment Standards
(UTS) in R315-268-48. All other required treatment standards associated with the waste will be met prior to disposal.
The basis for this variance is as follows; requiring this waste stream to meet the dioxin and furan treatment standards is inappropriate based on the incineration and recycling processes
that generate this waste. Due to those processes all the ash waste contains dioxins and furans; however, in accordance with regulations, only a portion of the waste needs to be treated
for those contaminants. The generator has previously analyzed each container of ash for metals contamination. If metals were below the toxicity characteristic concentrations described
in 40 CFR 261.24 (R315-261-24), the waste would be shipped to the Clive facility as Low-Level Radioactive Waste (LLRW) and disposed in the Class A Embankment. If metals were above the
Toxicity Characteristic concentrations, then the waste would need to be treated for those metals as well as all UHCs, including dioxins and furans. It is inappropriate to require treatment
of dioxin and furan contaminants in instances where characteristic metals are found in the waste when treatment is not required if metals are below characteristic concentrations in the
waste.
Furthermore, the stabilized ash was re-incinerated in an attempt to reduce the concentration of dioxins and furans in the ash. Re-incineration resulted in very little reduction in concentrations
of the dioxan furan contaminants. It would be inappropriate to require this additional incineration step in order to attempt to meet the standards.
EnergySolutions proposed to confirm that the waste meets all required treatment standards with the exception of the dioxan and furan UHC standards and then microencapsulate the ash residue
following approved requirements for MACRO in the state-issued Part B Permit. Macroencapsulation is an approved process that provides further isolation from the environment and will avoid
unnecessary additional re-attempts of incineration of the waste. Final disposal of the waste will occur in the Mixed Waste Disposal Cell at the EnergySolutions Mixed Waste Facility.
A 30-day public comment period to receive comments on the Dioxan Furan Ash treatment variance request will commence on [Comment period start date] and end at 5 p.m. on [Comment period
end date].A public hearing has been scheduled at [time] on [day of week], [Date] at [name and location of hearing site].
