Subject: Follow-up Industrial Facility Inspection
Charlotte Bioenergy Facility, LLC
Dear Miguel Lugo:
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 storm water 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 Area- 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:

2) Stormwater Pollution Prevention Plan (SWPPP)
A Stormwater Pollution Prevention Plan (SWPPP) has been developed, recorded, and implemented. However,
several deficiencies were observed.
3) Qualitative Monitoring
Qualitative monitoring has not been conducted and recorded as required.
4) Analytical Monitoring
Analytical monitoring has not been conducted and recorded as required.
Thank you for the assistance and cooperation with the follow-up site inspection. The attached reports
provide details about follow-up 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 NCG060387, please contact Jeffrey Chandler
