All three outfalls discharge into an unnamed tributary thence into Catfish Bayou and are located in the Yazoo River Basin. Outfall 003 is currently permitted but the sedimentation pond for this outfall is not yet constructed since the landfill operations have not progressed into the western portion of the landfill.

***Turbidity outside the limits of a 750-foot mixing zone shall not exceed the background turbidity at the time of discharge by more than 50 NTU.

COD, pH, TSS, and Turbidity shall be monitored semiannually via grab sampling. Results shall be reported annually on Discharge Monitoring Reports (DMRs).

MDEQ has begun streamlining landfill storm water NPDES permits over the last few years and requiring the monitoring and reporting of a set of common parameters.  These parameters are: COD, TSS, turbidity, and pH.  Although turbidity was removed as a monitored parameter in the current permit when the permit was reissued in July 2020, turbidity has been reinstated as a monitored parameter in the proposed permit to remain consistent with other landfill storm water NPDES permits.
