Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Melanie Kemp, with the Asheville Regional Office, conducted a Pretreatment Compliance Inspection
(PCI) of the Tryon’s Pretreatment Program on September 20, 2023. Deborah Bradley (Pretreatment
Coordinator/WWTP ORC) was present during the inspection.
Overall, the program appears to be in compliance with Federal and State Pretreatment requirements.
The Town of Tryon’s Pretreatment Program has one Significant Industrial User (SIU): Tryon Finishing
Corp. Paperwork was readily accessible and organized.
During the file review, it was noted that there have been two copper exceedances within the last six
months. The SIU is pumping out their treatment basin and conducting an engineering analysis to
better understand the source of the copper. The ORC has not noticed that the copper violations
have impacted the WWTP. Two NOVs have been issued by the POTW but the industry is not in
significant non-compliance.

FILE REVIEW COMMENTS:
CoCs were missing from the SIU reports. SIU sampling results from April and July 2023 showed copper limits violations. The
POTW issued two NOV’s but the SIU isn’t in SNC yet. The SIU is pumping out their pretreatment basin and conducting an
engineering analysis to address this issue.
