Univar Solutions USA Inc. — Charlotte Facility
Dear Timothy Nightwine:
On February 14, 2023, Julianna Hawley 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.
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:
1) Stormwater Pollution Prevention Plan (SWPPP)
A Stormwater Pollution Prevention Plan (SWPPP) has been developed, recorded, and
implemented; however, no feasibility study or recent non-stormwater discharge evaluations were
observed. The facility should ensure that all parts of the SWPPP are included as required by their
permit.
2) Qualitative Monitoring
Qualitative monitoring has been conducted and recorded for Outfall #001. The facility should
contact NCDEQ to verify if qualitative monitoring is required at all outfalls.
3) Analytical Monitoring
Analytical monitoring has been conducted and recorded.
