RE: Discharge Monitoring Report — July through December 2022 (Second Semi-Annual Period
of 2022)

Dear Ms. Kay:
On behalf of Tri State Gunite of NJ, L.P. (Tri State), please find attached results of stormwater outfall
sampling that was conducted on November 30, 2022, for the Tri State Gunite facility in Monroe,
Union County, North Carolina. Water samples were collected from the outfall SDO-1 by Tri State
personnel on November 30, 2022, in accordance with the sampling requirements of the permit.
Water samples were analyzed for total suspended solids (TSS), non-polar oil and grease and pH. The
November 2022 sampling results indicated that the TSS levels exceeded the permit requirements
and the pH was outside the acceptable range in the sampled outfall. Please note that pH was not
collected using a field meter. Rather it was analyzed in the laboratory. The Stormwater Discharge
Outfall Monitoring Report is included in Appendix A, the Stormwater Discharge Outfall Qualitative
Monitoring Report is included in Appendix B, and a complete laboratory analytical report is included
as Appendix C.

Please note that the sampling frequency according to the recently renewed general permit has
changed from semi-annual to quarterly. Going forward stormwater sampling of the outfall will be
conducted on a quarterly basis during a representative rainfall event. The next quarterly sampling
event is scheduled to be conducted between January and March 2023 during a representative rainfall
event. Please do not hesitate to contact me at [phone], if you have any questions or
comments.
Sincerely,
Joanna Alley, P.E.

All permits require qualitative monitoring to be performed during a"measurable storm event"
I j
A"measurable storm event'is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
interval does not apply if the permittee is able to document that a shorter interval is representative for
local storm events during the sampling period, and the permittee obtains approval from the local DEMLR
Regional Office

Dear Joanna Alley:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 11/30/2022 for the analyses presented in the
following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA(including 40 CFR 136
Method Update Rule May 2021) unless otherwise indicated.
Certain parameters (chlorine, pH, dissolved oxygen, sulfite...)are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any Feld parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information.
