FILE REVIEW COMMENTS:
18. The POTW investigated an odor complaint at the IPC facility in July 2022. The POTW determined that IPC's chemical feed pump system
used to reduce/eliminate the odors was not operating properly. IPC implemented corrective actions including the usage of a hydrogen peroxide
chemical feed system to reduce/eliminate the odors. The POTW had also investigated a previous odor complaint at the IPC facility in February
2021. As a result of the July 2022 investigation, the POTW issued a NOV and civil penalty assessment to IPC.
22. The POTW's on -site certified laboratory performs LTMP analyses on conventional parameters and pH and temperature. Pace Analytical
Services has been contracted to perform the remaining LTMP analyses.
35. POTW performed SIU inspections on Teijin Automotive Technologies (6/29/22), IPC (9/8/22) and Hexagon Agility (5/6/22).
39. The POTW's on -site certified laboratory performs analyses on conventional parameters and pH and temperature for SIU sampling events.
Pace Analytical Services has been contracted to perform the remaining IUP analyses.
41a. Teijin Automotive Technologies and IPC both contract Statesville Analytical to perform IUP analyses. Hexagon Agility contracts Pace
Analytical Services to perform IUP analyses.
46. The POTW issued NOVs to Teijin Automotive Technologies for BOD, COD, ammonia, TSS and zinc limit violations in September 2022
and a flow limit violation in November 2022. Teijin Automotive Technologies was also issued a NOV for the late reporting of the September
2022 flow monitoring report. The POTW will assess a civil penalty (based on point system) to Teijin Automotive Technologies for all the
above -noted violations.
SUMMARY AND COMMENTS:
The records reviewed during the inspection were organized and well maintained. The POTW's Industrial Pretreatment Program was being
properly implemented.
