Statewide General Waste Discharge Requirements (WDRs) for Wineries

The State Water Board has developed General WDRs for winery process water (Winery Order) for wineries and other similar facilities (collectively referred as wineries) with activities related to producing wine or grape juice that generate winery waste and discharge it to land for reuse or disposal. The Winery Order is applicable statewide and is intended to streamline and improve permitting consistency.

The State Water Board will continue to engage the public and stakeholders as part of the Winery Order implementation process and this website will be updated with related information as it becomes available.

On January 20, 2021, the State Water Resources Control Board adopted Resolution No. 2021-0001 for the California Environmental Quality Act Mitigated Negative Declaration for the Waste Discharge Requirements for Winery Process Water and associated General Order.

  If you have questions on the adopted Winery Order, please contact staff at (916) 341-6904 or


All guidance materials posted on this website are intended to provide the regulated community and the public with a general understanding of the Statewide Winery Order from a staff perspective. These materials are informational only, and are not intended to implement, interpret, or create new requirements. In the case of any conflict with existing statutes, regulations, or orders, the actual statute, regulation, or order governs. For specific questions, please contact staff of the State Water Board or the appropriate Regional Water Quality Control Board (regional water board).

The Statewide General Waste Discharge Requirements for Winery Process Water (Winery Order) sets criteria for facilities that meet the necessary requirements to be considered “exempt”.

Although the facility may not be required to enroll in the Winery Order, other Water Boards (State Water Resources Control Board and the regional water quality control boards) regulatory program enrollment may be required depending on facility operations (e.g., National Pollutant Discharge Elimination System (NPDES) Wastewater Permits, NPDES Industrial Stormwater General Permits, other Waste Discharge Requirements, or Irrigated Lands Regulatory Program, etc.).

Facilities may operate in accordance with the guidelines below, but may still pose a threat to water quality due to a high concentration of similar discharges in the same watershed or due to its location where groundwater quality is already degraded and more stringent discharge limits are in effect. If these conditions may apply, the Water Boards may require the Discharger to enroll in the Winery Order. The Discharger is encouraged to contact the State Water Board for more information at

To be considered exempt, a winery must produce less than 10,000 gallons of process water per year and agree to the following criteria. Please read the Winery Order for more detail.

  1. The Discharger shall not discharge waste:
    • To surface waters or surface water drainage courses.
    • That is classified as "hazardous," as defined in California Code of Regulations (CCR), title 23, division 3, chapter 15, article 2, section 2521, or classified as "designated," as defined in Water Code, division 7, chapter 3, section 13173.
    • That is untreated or partially treated from the treatment system.
    • To land not owned, operated, controlled, or contracted by the Discharger.
  2. The Discharger shall implement the following management practices:
    • Manage winery product, winery waste, and winery waste areas (e.g., storage, loading, conveyance, treatment, and disposal areas) to prevent, mitigate, and promptly clean up any spills.
    • Maintain all winery waste within property boundaries and within appropriate onsite use areas (e.g., loading, processing, storage, treatment, disposal, and reuse areas).
    • Manage winery waste to minimize nuisance conditions (e.g., objectionable odors; mosquitoes in ponds, ditches, and other open storage areas).
    • Manage stormwater that contacts winery waste as process water. Protect stored process solids from precipitation to minimize process water generation.

A winery may be asked to provide documentation that substantiates a discharger’s compliance with these criteria in obtaining a local use permit from a county or city permitting authority. The Water Boards are not required to review or provide exemption certifications. Therefore, the winery will need to work directly with the county or city permitting authority on the required documentation.


Hazardous waste is referenced in the CCR title 23 reference, which refers to Title 22 CCR, division 4.5, chapter 11, article 1 section 66261.3 for the core definition.

Designated waste” means either of the following:

  • (a) Hazardous waste that has been granted a variance from hazardous waste management requirements pursuant to Section 25143 of the Health and Safety Code.
  • (b) Nonhazardous waste that consists of, or contains, pollutants that, under ambient environmental conditions at a waste management unit, could be released in concentrations exceeding applicable water quality objectives or that could reasonably be expected to affect beneficial uses of the waters of the state as contained in the appropriate state water quality control plan.
