Permits & Engineering Comments:
This is a permit renewal for a discharge into Belews Creek. This facility is in the process of expanding
to 0.2 MGD with an ultimate design flow of 0.385 MGD. Per Mike Mickey (W-SRO), permit should be
renewed without previous 0.1 MGD limits page. Within the past twenty four months this facility had
violations of BOD, TSS and Fecal Coliform. Since expansion to .2 MGD will be completed in the near
future, Permits and Engineering will recommend existing limits at expansion flows of .2 MGD and .385
MGD only with /monitoring reflective of a class II facility.
