Subject: RE: Residuals land application forms
3im,
Prior to us issuing DuPont a permit to land apply the lagoon residuals' DuPont will need to provide' in
writing, confirmation from owm that that material is not covered by their programs and that DuPont may
seek a owQ permit for land application of the residuals. It also needs to be made clear to them than that
under a owQ land application permit they will need to apply the material at an agronomic rate and not as
a fill material. In the meantime, they are welcome to send the material to a permitted landfill.

After you sent this email addressing your discussion with Larry Stanley, z sent a copy of the PpoA
results to Larry. The ppox results where separate from the TcLP data in the email that you forwarded
Have you received a response from Larry concerning the management of this material?
z have a email drafted, that needs to be updated to send to Mike znhnson at DuPont, but I'm waiting for
some concurrence before sending. If Ed hasn't forwarded the draft email to you, let me know and z can
send. If you wish to respond to mike instead' that would be fine by us' to insure DuPont is directed in
the proper way to permit said material or to convey owQ's concerns about the proposed plan and conditions
that would be associated with the proposed management of the residuals.
At this time z will be in the office most of the week. If you wish to discuss' please give me a call at
your convenience.

Thanks for talking with me some on Thursday about the DuPont facility. Attached are the sediment
sampling data that we received from DuPont. Prior to permitting DuPont to land apply the alum residuals
as a soil amendment (not fill)' we will request that DuPont provide to us in writing a statement from own
clarifying whether or not the alum residuals must handled by the owm's Hazardous waste Section or other
owM permitted facility.

3im:
Thank you for calling me today and discussing DuPont's options to remove the river water sediment from
our basin and placing it in our on -site Borrow Area.
Per your request, attached are the analytical results for the required seven samples of the sediment.
All analyses were done by the cnmpuchem lab in Cary. The one outstanding analyte is the Prox result that
mC-owm is especially interested in, as this analysis is performed at another lab. z will work to get
that result xsxP' but it will no doubt be at less than I ppb levels.
You will see that Sample 01 was run as a duplicate, and samples 02 through
07 were all run as single analyses.
z also color coded the table for my own use. The cells that are not colored were "non -detectable" or
"less than pmL^ The cells colored blue had positive measurable concentrations of the analyte. The
cells colored yellow had laboratory qualifiers on them' for which ^3^ means the result was estimated due
to a data quality issue and the result was less than the mlL, and a ^n^ qualifier means that
contamination was seen in either the trip blank' equipment blank or method blank.
