FILE REVIEW COMMENTS:
7. The POTW has issued US Cotton an Industrial User Permit (IUP); however, the SIU has not initiated a discharge to date.
17. The POTW reported weekly average effluent TSS violation in January 2021. Effluent total nitrogen (TKN & nitrite + nitrate) was not
monitored in February 2021. Effluent total residual chlorine violations were reported in June 2022. An effluent chronic toxicity failure was
reported in August 2022.
22. The POTW will revise the Long Term Monitoring Plan (LTMP) to update detection levels (page 4) and remove SIU listing (page 2) and the
last paragraph (page 3) that identifies contracted company that performs bio-solids sampling.
35. The POTW performed the inspection at Spartan Dyers on 12/12/22. The POTW maintains consistent contact with US Cotton regarding
operations. It is recommended that the POTW staff perform annual inspections in the future at the US Cotton facility even if the facility is not
discharging process wastewater.
39. The POTW performs monthly sampling in lieu of the SIU. The POTW contracts Pace Analytical Services to perform all LTMP
and IUP analyses.
SUMMARY AND COMMENTS:
The pretreatment records were organized and well maintained. The POTW's Industrial Pretreatment Program was being properly implemented.
