FILE REVIEW COMMENTS:
17. An effluent total residual chlorine daily maximum limit violation was reported in November 2021.
20. Special Metal's Consent Order expired on 1/21/22.
25. Overall, all effluent LTMP analyses were reported on the eDMRs; however, effluent zinc results were not included.
35. The POTW performed the SIU inspections on 9/30/21 (Technibilt) and 7/27/21 (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 SIU analyses.
41a. Technibilt and Special Metals both contract Pace Analytical Services to perform IUP analyses.
46. The POTW issued NOVs to Special Metals for chromium IUP limit violations in August and November 2021 and nickel IUP limit
violations in July, August and September 2021. Special Metals was also issued NOVs for the failure to monitor fluoride during the fourth
quarter of 2021 and chromium and nickel during the week of 7/12/21 — 7/16/21. Technibilt was issued a NOV for the failures to monitor pH
during July 2021; however, the POTW will need to verify if the SIU did violate the IUP pH monitoring requirement.
SUMMARY AND COMMENTS:
The records reviewed during the inspection were organized and well maintained. The POTW must ensure the nickel reporting level (Meritech
and Pace Analytical Services) and cyanide reporting level (Pace Analytical Services) is at or below the required IUP reporting levels.
The POTW will need to amend all applicable eDMRs to include the effluent zinc results. In addition, the POTW must rescind the NOV to
Technibilt for pH monitoring violations (January, June and July 2021) if the SIU did meet the IUP's monitoring requirement following
verification.
Overall, the POTW's Industrial Pretreatment Program was being properly implemented.
