Subject: Industrial Facility Inspection
Wire -Bond — 400 Rountree Road, Charlotte
Dear Mr. Brown:
On August 24, 2018, Ron Eubanks of Charlotte -Mecklenburg Storm Water
Services (CMSWS) conducted an inspection of the above referenced facility as a
requirement of the City of Charlotte's NPDES Permit, NCS000240, Part II Section H.
Inspection authority is granted by Charlotte City Code Chapter 18, Article III, Section
18-82. At the time of inspection, the facility was observed to be in compliance with the
City of Charlotte Storm Water Pollution Control Ordinance. There were some storm
water pollution concerns noted and the following recommendations are provided:
1) Charlotte Storm Water Pollution Control Ordinance Review
• Stormwater System — Stormwater runoff drains by sheet flow and discharges from
the property via eight (8) outfalls. Inlet and outlet protection (i.e., Filtrexx filters
and straw bales) were observed at several stormwater catch basins and outfalls on
the property. Facility staff indicated that lot sweeping activities are conducted
twice a week to remove sediment accumulation. It is recommended that Wire -
Bond continue using inlet/outlet protection and lot sweeping activities to address
stormwater pollution on the property.
Erosion Issues — There was minor erosion observed near the fence line on the
western property boundary. It is recommended that the eroded area on the
property be stabilized with ground cover and/or rip rap to control stormwater
erosion.
Structural Stormwater BMPs — Filtrexx filter best management practices (BMPs)
are being used at each of the outfalls on the property to address elevated metals in
stormwater runoff from the property. It is recommended that the Filtrexx filters
be routinely inspected and replaced as needed.
Waste Storage/Disposal Areas — There are two (2) municipal waste dumpsters and
five (5) scrap metal containers located on the property. The municipal waste
dumpsters were covered and appeared to be in good condition; however, some of
the scrap metal containers were uncovered. It is recommended that the scrap
metal containers be covered to prevent stormwater accumulation and reduce
metals in stormwater runoff.
