FILE REVIEW COMMENTS:
7. The City has issued US Cotton an Industrial User Permit (IUP); however, the SIU has not initiated a discharge to date.
17. Effluent fecal coliform limit violations were reported from January through July 2023. In addition, effluent TSS limit violations were
reported from March 2023 through July 2023. These violations were attributed to an elevated solids inventory being maintained in the WWTP
due to challenges associated with the removal of solids (land application, etc.). The City contracted a company in June 2023 with a portable
belt press to lower the solids inventory via dewatering and landfill disposal. The WWTP returned to compliance in August 2023.
22. The City will revise the Long -Term Monitoring Plan (LTMP) to remove both the twice per year monitoring for uncontrollables and SIU
listings.
25. The City staff will need to revise and resubmit the April 2023 and any additional eDMRs to correct the units of measurement of all
applicable metals sampled during the LTMP sampling events. In addition, the quarterly effluent cyanide results (units of measurement) will need
to be revised (if applicable) starting with the January 2022 eDMR.
35. The City performed the SIU inspections on 12/8/23 (Spartan Dyers) and 8/17/23 (US Cotton).
39. The City performs monthly sampling in lieu of the SIU. The POTW contracts Pace Analytical Services to perform all LTMP and IUP
sampling and analyses.
46. The City issued Spartan Dyers a Notice of Violation (NOV) for an oil & grease limit violation in July 2023. Note: The NOV was not issued
within the timeframe listed in the Division -approved Enforcement Response Plan (ERP) due to staff changes.
SUMMARY AND COMMENTS:
The City will update their LTMP to remove both the twice per year uncontrollable sampling and listing of SIUs. The City's Pretreatment staff
must ensure all enforcement actions (NOVs, etc.) are issued within the timeframes listed in the Division -approved ERP. The City staffmust also
review and revise/resubmit all applicable eDMRs to ensure all LTMP and quarterly (cyanide) results have been properly reported starting with
the January 2022 eDMR.
The pretreatment records were organized and well maintained. Overall, the City's Industrial Pretreatment Program was being properly
implemented.
