Dear Mr. Hewett:
On December 6, 2018, Jenny Graznak of this office, met with Michael Glass, Operator in Responsible
Charge (ORC), to perform a Compliance Evaluation Inspection at the City of Randleman wastewater
treatment plant. This type of inspection consists of two basic parts: an in-office file review and an on-
- site inspection of the treatment facility. The attached EPA inspection form details the areas that were
evaluated during this inspection. Significant observations from the inspection are described in the
inspection summary portion of the form.
The inspection found the facility to be compliant with NPDES permit requirements. If you have any
questions regarding the inspection or this report, please contact Jenny Graznak
(iennv.araznak(a ncdenr.gov) or me (sherri.kniqhtncdenr.gov) at(336) 776-9800.

Section D Summary of Finding/Comments(Attach additional sheets of narrative and checklists as necessary)
1.The operators are certified to perform the following field parameters: total residual chlorine, dissolved
oxygen, and pH. However,the operators are also testing the effluent for ammonia to use for process
control purposes. Please be adivsed that any data collected on the effluent must be reported on the
DMR, per the NPDES permit.Therefore,the operators should sample for ammonia prior to final
effluent in order to use for process control only.
2. The facility has a significant violation history, mostly BOD violations in the last 24 months.The
operators described numerous dissolved oxygen and foam issues.They requested and received
technical assitance from Gary Hudson multiple times during this time period. Mr. Glass stated that the
plant has been running more smoothly since the summer of 2018.
