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 Storrnwater 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 and zinc
• Outfall SDO-3 for total zinc
• Outfall SDO-6 for pH, total copper and zinc
• 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 second-
ary containment to a stormwater outlet onsite. The investigation into the source of the discharge is contin-
uing and we will provide updates as soon as we can definitively confirm. We will continue to conduct
monthly sampling while looking for solutions to the continuous benchmark exceedances for copper and
zinc. 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 (919) 563-752 L
Sincerely,
_x �

Subject: Report of Stormwater Outfall Inspection and Sampling - July 2020
Industrial Connections & Solutions / ABB
6801 Industrial Derive, 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 (Slue 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 July 23, 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 1.56 inches of rain during the storm event.
Blue Ridge personnel observed the stormwater discharge at outfalls SDO-1 through SDO-3, SDO-6, and
SDO-7 and completed stormwater discharge outfall (SDO) qualitative monitoring report forms for each of
these 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 (except an elevated pH in SDO-6). 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.
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 August 31, 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.
