Chris Johnson pulled me in on a call he had with EPA RTP yesterday. There were a lot of questions on both sides during
that call and | am a little worried about the cart being before the horse asvve have samples in-house already. Sharing the
thread below.

I think Chris captured it. I do have something to add. I have not been privy to any discussions regarding the sampling
plan, sodisregard ifthese things have been discussed. Ataminimum:
0 1 would recommend initiating chain -of -custody for these samples at collection.
OEQ-CFVV_00013371

* | think it would be prudent to include Field Blanks with this sampling event, especially with the target ana|vte(s)
otinteveut.
w Field duplicates, at least one for each sampling team, might also be considered.
* | would have a plan for dealing with divergent data results since samples are being split between only two labs.
* Consider how the data will be used if reporting levels between the two labs are significantly different.
* | would get copies of both labs' Standard Operating Procedure for the analysis to ensure we have an
understanding ofhow each set are handled and analyzed. Ensure that each region (i.e., FRO andVViRO) is
collecting and handling the samples inthe same manner. Clean technique?
w Ensure that samples will be treated similarly upon receipt at each lab (e.g, stored at room temp vs under
refrigeration until analysis).
w Ensure our lab treats each set ofsamples similarly upon receipt. It is my understanding that the first set of
samples, received atroom temperature are being stored under refrigeration.
* 1 would include a detailed description of our procedure for collecting and subsampling/splitting of samples in the
(IAPP.
* | would consider requesting math�
matrix in
itial ateach site.

Subject: RE: Discussion for sampling and ana|ysis in VVi|mington
I will review Andrew's email and connect with the regional offices.
I was not able to answer all of EPA's questions. Some of them include:
What isthe status ofthe OAPP? | told them that acommittee was working onitand someone from that group
could address this.
OEQ-CFVV_00013372

What specific target analytes are we interested in seeing? (Some ana|ytes are qualitative / others can be
quantified)
Who will be responsible for dissemination of results and how will that take place?
Our sample bottles are5OOmLbutthe|abprefeolLofsamp|eforpossiNedi|WdonandCUCreasons. For the time being,
they are OK with getting J of the 500mL bottles for each site, but a single one'|kersamp|e is better from a
reproducibility standpoint. Preservation will be nitric acid / still waiting to find out about shipping / storage temperature
— it may be discussed in the document that Andrew Lindstrom sent, I haven't had a chance to review yet.
Apparently, there have been other related sampling events in the last few months. Some were taken byeither EPA or
N[SUabout amonth ago with noresults asofyet. Apparently, there were results from December IOl6of~1OOpptnear
Tarheel / Smithfield Processing and upwards of 6000ppt at Lock & Dam #3 / Huske Dam near the company outfall.
It was suggested that check samples be prepared at a couple different levels to confirm recovery since two labs will be
running the tests. I believe Mark Strynar is going to prep those samples.
We can have results in 1'2vveeks after samples have been submitted
- Their detection limits are from —10ng up to a max of —500ng. Any samples recovering above the upper limit are
They are prepared tohandle amaximum ofSUsamples. Apparently, this was the number that was previously
discussed.
Their method can detect a number of possible constituents that may be encountered from the company's
outfaU. (We will need to either provide a list ofana|ytes of concern or be prepared to deal with any that might
be reported.)

the call and | want tumake sure | didn't forget anything.

Chris — will let you discuss this with the Regional Offices rather than getting in the middle of the communication.
Share any updates from your call. Thanks.
VVejust finished the risk assessment contcall. EPA isworking ontheir re -review toinclude the ingestion ofwater
pathway.
As I understand, the original TSCA risk assessment focused on work exposure via inhalation and dermal.
I still need to forward you the DEQ/DHHS conf. call info.
