Dear Mr. Westcott,
As discussed during our 11/8/2022 phone call, 3M Pittsboro received two notice of violations and
intent to assess civil penalty for Permit number WQ0020808 on November 4th, 2022. The NOVs
were dated October 7, 2022. However, the notice listed incorrect contact information causing a
delay in the facility's receipt of these notices.
The contact information for 3M Pittsboro was updated during the call. Additionally, I have included
the updated facility information below.

NOV-2022-PC-0559 alleges that sample location 003 was missing the flow parameter on
1/31/2022 for the reclaimed water distributed. However, permit W00024838 states the facility
shall report the monthly estimate for the flow for reclaimed water distributed from the town of
Pittsboro rather than the daily flow amount. See a copy below of the table from attachment A
under permit WQ0020808.

Based on the monthly requirement outlined in the permit, it is 3M Pittsboro's understanding that
this requirement was met with the monthly average effluent for WQ01 disclosed on page 3 of 4
for the Non -Discharge Monitoring Report (NDMR) submitted for January 2022. During our
discussion, guidance was provided regarding this NOV that 3M Pittsboro include the average
daily flow for PPI 003 for each calendar day to better accommodate the state database input
system. 3M Pittsboro has updated this NDMR to reflect this change and is submitting an updated
NDMR for January 2022 with this communication via email and hard copies sent to the Division of
Water Resources Information Processing Unit. Moreover, 3M Pittsboro plans to submit updated
copies of previously submitted NDMRs for 2022 to include the average daily flow for PPI 003, to
the Division of Water Resources. We also will plan on reporting the average daily flow for PPI 003
for each calendar day on future NDMRs.
Additionally, NOV-2022-LV-0599 alleges, per permit condition 9.e, the permittee shall report
within 24 hours of first knowledge any time self -monitoring indicates the facility has gone out of
compliance with its permit limitations related to a potentially higher value for the daily max for
Turbidity at sample location 001 on 2/3/2022. After investigating this item, it has been determined
that there is a typo on the submitted NDMR and that an exceedance of the turbidity limit did not
occur. Therefore, notification to the regional office was not required since the parameter was
within permit limits. 3M Pittsboro has corrected this information for the February 2022 NDMR and
is submitting the corrected NDMR for February 2022 with this communication via email, and hard
copies sent to the Division of Water Resources Information Processing Unit.
In summary, 3M Pittsboro is submitting updated NDMRs for January and February 2022 to
address NOV-2022-PC-0559 and NOV-2022-LV-0559. 3M Pittsboro plans to resubmit previous
2022 NDMRs to include the daily average flow for 003. 3M Pittsboro will implement additional
administrative controls for quality assurance of submitted NDMRs.
Lastly, 3M Pittsboro would like to request a rescission of the abovementioned NOVs since no
violations actually occurred.
If you have any questions or comments regarding this submittal, please feel free to contact me.
