Winery Facilities

The State Water Board developed statewide General Waste Discharge Requirements (WDRs) that address land discharge of process water from wineries, grape juice storage facilities and wine distillation facilities (Winery Order). The Winery Order applies to facilities that discharge winery process waste to land for the purpose of disposal or reuse (including the use of treated process water for agriculture or landscape irrigation and the use of residual solids from winery processing as a soil amendment).

Tier Classification

Dischargers are classified into regulatory tiers based on the total volume of process water discharged annually from the winery prior to treatment, e.g. discharged to a pond, land application area (LAA) or subsurface disposal system (SDS). Application, requirements, fees and monitoring/reporting requirements correspond to the complexity of the discharge regulated under each tier.

Process Water Discharge

Tier 1    10,000 – 100,000 Gallons Per Year

Tier 2    100,001 – 300,000 Gallons Per Year

Tier 3    300,001 – 1,000,000 Gallons Per Year

Tier 4                  > 1,000,000 Gallons Per Year
