7. The City of Conover implements the Pretreatment Program for two SIUs (both CIUs) that ultimately discharge into the City of Newton's
WWTP.
35. The POTW performed the SIU inspections on 6/15/23 (Wanzl) and 6/20/23 (Special Metals).
39. The POTW's on -site certified laboratory analyzes BOD, TSS, ammonia, COD, and pH. Meritech Labs has been contracted to perform all
remaining LTMP and IUP analyses.
41a. Wanzl and Special Metals both contract Pace Analytical Services to perform IUP analyses.
46. The City issued a NOV to Wanzl for BOD and TSS limit violations in October 2023. Special Metals was issued a NOV for a nickel limit
violation in October 2023.
SUMMARY AND COMMENTS:
The Pretreatment staff must ensure that the chain of custody form for the parameters analyzed at the on -site lab (BOD, TSS, etc.) identifies the
parameter, sample type, and preservative (if applicable). In addition, this Office recommends maintaining a copy of the pH calibration log (IUP
sampling) with the pretreatment files.
The records reviewed during the inspection were organized and well maintained. The City's Industrial Pretreatment Program was being
properly implemented.
