Dear Jamie Hayes:

On January 11, 2024, Lauren Bradley 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; however, the following observations were made:

1) Charlotte Storm Water Pollution Control Ordinance Review
 Outdoor processing – Blue staining was observed outdoors on the ground around the condensation
discharge line for the air-conditioning unit, which is located near the powder coating section of the
facility. CMSWS recommends that the facility determine the sources of the blue discharge and implements
a Best Management Practice for the air-conditioning condensation discharge to protect water quality.

The inspection was also conducted as part of a cooperative working agreement between Mecklenburg County and the
North Carolina Department of Environmental Quality (NCDEQ) – Division of Energy, Mineral and Land Resources
(DEMLR). NCDEQ – DEMLR has been copied on this report and made aware of the following observations regarding the
facility’s NPDES stormwater permit:

2) Stormwater Pollution Prevention Plan (SWPPP)
A Stormwater Pollution Prevention Plan (SWPPP) has been developed, recorded, and implemented.

3) Qualitative Monitoring
Qualitative monitoring has been not conducted and recorded.

4) Analytical Monitoring
Analytical monitoring has not been conducted and recorded for all outfalls.

Thank you for the assistance and cooperation with the site inspection. The attached report provides details about
inspection observations and should be self-explanatory. Please contact me at [phone] if you have any questions or
need additional information. For questions specifically regarding your State-issued NPDES Stormwater Certificate of
Coverage NCG030486, please contact Jerry Eplin with NCDEQ – DEMLR at [phone].

Thank you,
