Hey Jerry,
Attached is our Tier 3 response and action plans regarding COD exceedance in Outfall 2 for Frito-Lay, Charlotte NC.
General Permit NO. NCG060000
Also attached are the most recent analytical results along with the retesting of Outfall 2 mentioned in the action plans.
Let me know if you have any questions!

Tier III Stormwater Action Plan for COD Exceedances on Outfall 2
Frito-Lay
2911 Nevada Blvd, Charlotte, NC
General Permit NO. NCG060000

Table of Contents
i. Documentation of the four benchmark exceedances
ii. An inspection report that covers the industrial activities within the drainage area of
the outfall with the exceedances (including the date of the inspection and the
personnel conducting the inspection),
iii. An evaluation of standard operating procedures and good housekeeping procedures,
iv. Identification of the source(s) of exceedances,
V. Specific actions that will be taken to remedy the identified source(s)with a schedule
for completing those actions, and
vi. A monitoring plan to verify that the Action Plan has addressed the source(s).

i. Documentation of the four benchmark exceedances
• 3/14/2023 - COD 371mg/L
• 8/7/2023 - COD 823mg/L
• 10/18/2023 - COD 183mg/L
• 2/11/2025 - COD 489mg/L
ii. Inspection report
Inspection of Outfall 2 and industrial activities within the draining area was
conducted on 3-14-2024 by the EHS Manager and EHS Associate Representative.
Outfall 2 is a concrete lined drainage ditch that collects overland flow from the
west side of the facility that includes the potato unloading area, the WWTP and the
out of use coal ash storage silo.
Evaluation of standard operating procedures and good housekeeping procedures
Good housekeeping procedures include but are not limited to checking and
replacing boom socks, clearing litter and leaf buildup, and One Environmental
Group quarterly BMP Maintenance and sampling.
Standard operating procedures within the drainage area of Outfall 2
include regularly cleaning up potato waste from the potato dump area.

iv. Identification of the source(s) of exceedance
After investigating Outfall 2, the EHS Team believes that the sample taken
on 2/11/2025 showing a concentration of 489 mg/L was mislabeled and
corresponds to Outfall 1. On 2/11/2025 it says the concentration for Outfall 1 was
91 mg/L. We believe that 91 mg/L should have been the concentration for Outfall
2 because the last three samples have all measured below 46 mg/L and there have
been no changes in operations that would affect the concentration of Outfall 2.
Outfall 1 has had higher COD concentrations the last two quarters which also
leads us to believe this was a mislabeling issue.
ONE Environmental group came back out on 3/5 and retested Outfall 2
due to the belief the samples were mislabeled on 2/11. The results from the retest
show Outfall 2 COD concentration of 69 mg/L. The attached document is the
verification and results of the retest.
V. Specific actions that will be taken to remedy the identified source(s) with a
schedule for completing those actions
Replace boom socks Completed on 3/14/2025
Clean area of leaf debris and litter Completed on 3/14/2025
One Environmental Group sampling Completed on 3/16/2025
Monthly inspection of Outfall 2 Ongoing Monthly
One Environmental Group BMP maintenance Ongoing Quarterly

vi. A monitoring plan to verify that the Action Plan has addressed the source(s)
One Environmental Group will be on a monthly sampling schedule until three
samples in a row are below the COD benchmark.

Dear Kaitlynn Bryan-Scaggs:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 2/11/2025 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.
