Subject: Stormwater Monitoring
Charlotte Bioenergy Facility
Dear Miguel Lugo,
On March 15, 2024, Michael Schley of Charlotte-Mecklenburg Storm Water Services (CMSWS)
sampled stormwater runoff from the subject facility located at 600 Johnson Road
in Charlotte,North Carolina. The monitoring was conducted under authority granted by
Charlotte City Code Chapter 18, Section 18-82.
The monitoring 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 monitoring results regarding the facility's NPDES permit.
Total rainfall during the rain event in which samples were collected at your facility was 0.48
inches. Rainfall data was reported by the United States Geologic Survey(USGS)real-time station
CRN-27(Rain Gauge at Hidden Valley Elementary School). CMSWS sampled stormwater runoff
from Outfall #3 (along entrance road above the creek). A summary table of results is attached to
this report.
Please see the attached table for more information on your monitoring results. CMSWS analyzed
the monitoring results from your facility by comparing them to Storm Water Permit benchmark
parameters as well as to local and state stream standards (CMSWS Action Levels and North
Carolina Water Quality Standards). The results indicate elevated levels of Fecal Coliform,
Copper, Total Suspended Solids (TSS), COD, and BOD in the facility's stormwater runoff.
Since the stormwater sample was not collected from a stream, the local and state surface water
quality standards do not apply; however, the results indicate the potential for polluted runoff
from the facility to negatively impact the receiving stream.
Based on this analysis, and under authority of the City of Charlotte Storm Water Pollution
Control Ordinance, CMSWS is continuing to work with Anaergia Services, LLC. to evaluate

current outdoor processes, material storage practices and overall housekeeping at the facility.
This includes both short-term and long-term actions to be taken in an effort to reduce these
elevated pollutant concentrations. In addition, as part of CMSWS follow-up actions, additional
Stormwater Monitoring and Industrial Inspections may be conducted at the facility.
Please contact me at(910) 523-8072 if you have any questions or need additional information.
