SUBJECT: Compliance Inspection Report
Randleman WWTP
NPDES WW Permit No. NCO025445
Randolph County
Dear Mr. Holcomb:
On 9/7/2023 a Pretreatment Compliance Inspection (PCI) was performed by Tricia Lowery and Jesse Barnes of
the Winston-Salem Regional Office. Lisa Osthues and Michael Glass were present for the inspection. The
purpose of this inspection was to determine the effectiveness of the City's pretreatment program, which
includes reviewing the files, POTW plant performance, industry monitoring data, and adherence to the
enforcement response plan (ERP). Details of the inspection can be found in the Pretreatment Compliance
Inspection Report.
There were no significant issues or findings noted during the inspection and therefore, a response to this
inspection report is not required. However, there was an item of concern involving exceeding lead limits of the
NPDES permit. Personnel with the City are continuing to work to discover the source of intermittent high lead
levels in the collection system.
If you should have any questions, please do not hesitate to contact Tricia Lowery with the Division of Water
Resources in the Winston-Salem Regional Office at 336-776-9691 or via email at [e-mail].
Sincerely,
DocuSiTgned by:

POTW INTERVIEW
17. Since the Last PCI, has the POTW had any NPDES Limits Violations?
If Yes, What are the Parameters and How are these Problems Being Addressed?
Exceeded limits for Pb (lead) in the months of March and April 2023. Due to
closing of all industries discharging to POTW, the flow has altered and may
have revealed higher lead concentrations POTW is in the process of trying to
trace lead. The city divided the collection system into quadrants and
conducted sampling at specific points. The POTW will conduct additional
monitoring to try and locate the source. It is believed illegal dumping (by
non-SIU) is occurring containing lead waste. One sample location in CS
system has inconsistent readings (to below POL to exceeding limit).
18. Since the Last PCI, has the POTW had any Problems Related to an Industrial
Discharge (Interference, Pass -Through, Blockage, Citizens' Complaints, Increased
Sludge Production, Etc.)?
