Re: NPDES Stormwater Permit Coverage Renewal COC #NCG030063
Industrial Connections & Solutions LLC — Stormwater General Permit NCGO30000
Dear Sir or Madam:
In accordance with our NPDES Stormwater Permit, Industrial Connections & Solutions LLC is notifying the
Division of Energy, Mineral, and Land Resources (DEMLR) of benchmark value exceedances for:
Outfall SDO-1 for total copper
Outfall SDO-6 for total copper
Outfall SDO-7 for total copper
As reported on July 28, 2020, we believe the pH exceedance for SDO-06 is caused by a leak in the secondary
containment to a stormwater outlet onsite. As of September 25, 2020, the valve inside of the secondary con-
tainment, which we believe was the source of the leak has been removed and the area sealed to prevent any
future discharges from the containment. We will continue to conduct monthly sampling while looking for
solutions to the continuous benchmark exceedances for copper. The following documents are enclosed:
1. Stormwater Discharge Monitoring Report
2. Lab Results from Sampling (Meritech, Inc.)
3. Qualitative Monitoring Reports (SDOs) — Blue Ridge Geological Services, Inc.
If you have any questions about this report, please contact me at [phone].

Subject: Report of Stormwater Outfall Inspection and Sampling - August 2020
Industrial Connections & Solutions / ABB
6801 Industrial Drive, Mebane, North Carolina
Dear Ms. Stennis:
As authorized by acceptance of our proposal dated September 2016 and your requests to continue
sampling, Blue Ridge Geological Services, Ina (Blue Ridge) personnel performed additional
environmental services at the subject site. The work was performed in general accordance with the
Stormwater Pollution Prevention Plan (SWPPP) prepared for the subject site as well as the requirements of
NCDEQ NPDES General Permit. On August 29, 2020 Blue Ridge personnel performed a stormwater
outfall inspection and sampling event at the subject site during a measureable rainfall event. Rainfall data
was obtained from a nearby weather station using Accuweather. According to the website, the area in the
vicinity of the subject site received approximately 0.06 inches of rain during the storm event.
Blue Ridge personnel observed the stormwater discharge at the site outfalls and completed stormwater
discharge outfall (SDO) qualitative monitoring report forms for each of the outfalls. The SDO forms are
attached. The pH of the samples was measured in the field using an Oakton pH meter and recorded on the
SDO forms. No environmental issues were observed at the outfalls during this inspection. Field personnel
collected samples from each of the stormwater outfalls, placed the samples into labeled containers, completed
a chain of custody (COC) form, and submitted the samples and COC form to Meritech personnel. No sample
was obtained from Outfall SDO-2 since there was no flow on this date.
This inspection report and the SDO forms should be placed in the SWPP Plan or a file on site and they do not
need to be submitted to the NCDEQ. We will attempt to perform the next stormwater inspection/sampling
event at the site before September 30, 2020. We appreciate the opportunity to continue to assist you on
this project. Please contact the undersigned at if you have any questions regarding this report or if you
need additional assistance.
Sincerely,
Jeffrey L. Gerlock, L.G.
