Representative Outfall Stormwater Designation
Dear Mr. Khan:
During the April 5, 2022, DEQ technical assistance visit it was noted that 5 representative stormwater
outfall discharge points flow directly into the stormwater pond owned and maintained by CommScope.
As a result of this determination, I am requesting that our stormwater pond along with outfalls 8 and 9 be
designated as our representative outfalls for stormwater discharge. I have updated our SWPPP as
directed in the technical assistance letter to reflect the addition of our stormwater pond as a sample point
until final approval is given to classify the stormwater pond and outfalls 8 and 9 as our representative
stormwater outfalls. In addition, we are also evaluating the condition of catch basins and stormwater
conveyance piping to determine the need for replacement and or maintenance as mentioned in the DEQ
technical assistance letter. Lastly, continued efforts are underway to remove or cover metal components
stored outside that may contribute to elevated copper and zinc levels in our stormwater runoff.
If you have any questions, please feel free to contact me at 828-582-2702.
Sincerely,
Chris Graybeal
Environmental Engineer CommScope
