The effluent limits and associated total nutrient loading to Deep Creek developed as part of this study may be proposed as site-specific numeric interpretations of the narrative nutrient criteria for Deep Creek in the form of Level II Water Quality Based Effluent Limits via order of the Department. The only known affected discharger other than these two domestic wastewater treatment facilities is the South Woods Elementary RO WTP (Permit ID # FL0429333).
