The Department has prepared a draft permit and has made a tentative determination, subject to public comment or other information, to approve the proposed reauthorization and modification of subsurface discharges of treated sanitary wastewater. No change is proposed to the following outfalls: 21,050 gallons per day (GPD) from Outfall 001 using absorption trenches; 8000 GPD from Outfall 018 using absorption trenches; 5991 GPD from Outfall 019 using absorption trenches; and 1320 GPD from Outfall 020 using absorption trenches. A revised discharge is proposed of 2,750 GPD from Outfall 008 using absorption trenches. Also present at the facility are the following non-jurisdictional subsurface discharges under 1,000 GPD of treated sanitary wastewater through absorption trenches: Outfall 002 (600 GPD), Outfall 003 (600 GPD), Outfall 004 (600 GPD), Outfall 005 (600 GPD), Outfall 006 (600 GPD), Outfall 007 (600 GPD), Outfall 009 (660 GPD) and Outfall 10 (600 GPD), Outfall 11 (300 gpd), Outfall 12 (600 gpd) , Outfall 13 (300 gpd) , Outfall 14 (300 gpd) , Outfall 15 (400 gpd) and Outfall 16 (245 gpd). Previously existing Outfall 017 (450 GPD) will be decommissioned.
