Lon-
Duke is requesting the monitoring of this site be changed from quarterly to
semiannually. Since there is no significant changes between quarterly analytical results, I don't
have an issue with this requested change. We typically do change the monitoring frequency
for permits like this when requested.
Are you OK with this?
Thanks

Hello Mr. Rogers,
I wanted to follow-up on a request included in Duke Energy's Annual Infiltration Report for the Belews Creek Steam
Station submitted to the NCDEQ in October 2022. As part of the UIC permit,a quarterly sampling program from the
surface water source, Belews Lake,was requested by the NCDEQ and implemented by Duke Energy to confirm that
constituents of interest(COls) unrelated to Duke Energy site activities are acceptable for infiltration into the subsurface,
if present. To date, Duke Energy has completed six quarterly sampling events for the extended list of parameters shown
in the table below. Analytical results for these parameters have been below applicable groundwater standards under a
variety of seasonal conditions. The analytical data is included in the infiltration report. The October 2022 report
included a request to reduce the sampling frequency for these parameters from quarterly to semi-annually.
In summary, Duke Energy respectfully requests the NCDEQ's review of the proposed sampling frequency modification
described above.
Please feel free to contact me if you have any questions.
