Dear Miguel Lugo:
StormWater.CharMeck.org
On April 17, 2023, Michael Schley, Richard Farmer, John Thao and Craig Miller of
Charlotte -Mecklenburg Storm Water Services (CMSWS) conducted a follow-up inspection of the
above referenced facility under authority granted by Charlotte City Code Chapter 18, Article III,
Section 18-82.
At the time of inspection, the facility was observed to have improved site conditions in terms
of material storage and handling and overall housekeeping. The facility should continue
completion of corrective actions as described in all recently issued NOVs and follow related
guidance of CMSWS. The following observations were made during the re -inspection:
1) Charlotte Storm Water Pollution Control Ordinance Review
• Stormwater System — Remediation of the facility's stormwater system is ongoing from the
illicit discharges which recently occurred at the facility and resulted in multiple Illicit
Discharge NOV's. The facility should continue remediating all affected areas of the
stormwater system.
• Erosion Issues/Outdoor Material Storage — Interior roads throughout the facility were
observed to be improved since previous inspections but there was still considerable
sediment buildup and tracking. CMSWS recommends the facility continue to practice
sweeping and good housekeeping procedures to help protect water quality.
• Loading A solid waste compost byproduct was observed to be stored in a partially
covered area where it can intermix with stormwater and be tracked throughout the facility.
CMSWS recommends collecting the material in containers kept under cover to avoid the
material being intermixed with stormwater or being tracked through the facility during
loading and unloading operations.
The initial 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 the reports and made aware of the following observations regarding the facility's
NPDES stormwater permit:
