Subject: Industrial Facility Inspection
A O Smith Water Systems

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.
