1st Semi -Annual 2022 Storm Water Sampling

ARM Project No. 12-4003-14
Mr. Caulford:
In accordance with the North Carolina Department of Environment, and Natural Resources (NC DENR)
stormwater discharge permit, ARM collected the first semi-annual stormwater samples for 2022 at the
referenced facility on March 16, 2022.
The samples consisted of one stormwater grab sample from the facility stormwater outfall location, and
the sample was collected during the rain event in Laboratories clean, pre -preserved, laboratory -prepared
sample bottles. The sample was then delivered to Waypoint Analytical, which is a North Carolina -
accredited analytical laboratory. The sample was analyzed for oil and grease, total suspended solids
(TSS), copper, lead, zinc, and total toxic organic compounds (volatile and semi -volatile organic
compounds) via EPA Methods 624 and 625, per the permit requirements.
The attached Table 1 provides a summary of the analytical results (also attached), total flow, and total
rainfall. All parameters were below the permitted range benchmarks in the sample, except for the one
minor exceedance of copper. The zinc was not found to exceed as in previous sampling events. The
pH was performed in the field upon sample collection; was within the recommended holding time of 15
minutes; and showed results within the permitted range benchmark value of 6.0-9.0. The Stormwater
Discharge Monitoring Report (SDO), which also shows the analytical results for the outfalls are attached.
During sample collection, qualitative monitoring of certain parameters was performed and the
Qualitative Monitoring Report for each outfall is attached.
ARM appreciates the opportunity to provide environmental services to Mann -Hummel. As required by
the stormwater permit, please sign the SDO and then forward the report to the NC DEN R-Central Files
at the Division of Energy, Mineral, and Land Resources at the address shown on page 2 of the
Stormwater Discharge Monitoring Report. Please call us at 704-369-0621, if you have any questions.

All permits require qualitative monitoring to be performed during a "measurable storm event."
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.
By th15,signature, I certify that this report is accurate and complete to the best of my knowledge:

Waypoint Analytical, LLC (Charlotte) received sample(s) on 3/16/2022 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 field 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.
