Overview of the DEQ Requirements Discussion Flow Chart Guidance Document for a Winery Wastewater System

Why are we concerned about Wastewater?

Total Phosphorus Nitrogen Sodium Wastewater Characterization Chloride pH Biochemical Oxygen Demand 5 day (BOD5)

Limiting Parameter BOD5 Residual Sugars Unfiltered Sediment

• Keep sanitary water separate from Process water • Separate soils whenever possible including: Wastewater Quality • Skin, stems, leaves General Recomendations • Sedimentation from fermentation for Wineries tanks • Lees • Aeration is recommended • Design for 2-3 days retention time

Discharge to Municipal system? Discharge to Land or subsurface? Who do I • Contact municipality • Contact DEQ, Groundwater need to call? Permit Section • No DEQ permit required

Process Wastewater needs a DEQ Permit (Not going to a Municipality)

• Natural Resources and Environmental DEQ Protection Act Requirements • Part 22, Groundwater Quality Rules

Permit Applicability • 5 year permits • Annual fees apply • Certified Operator may be required • Any permit application requires a soils review • Authorization to discharge once permit is ISSUED • One size does not fit all!!!
