The discharge of wastewater from the Woodbridge Winery is regulated by Waste Discharge Requirements (WDRs) Order R5-2012-0103, while the discharge of wastewater from Turner Road Vintners is regulated by WDRs Order 99-103. Regional Board staff has reviewed the 24 March 2017 Discharge Plan that was submitted after the Discharger transferred approximately 795,000 gallons of process wastewater from the Woodbridge Winery to the Turner Road Vintners facility. The wastewater was transferred as part of the Discharger's spill mitigation plan developed in February 2017. The plan proposes to discharge the stored wastewater into the Turner Road Vintners wastewater treatment and disposal system at a rate of 200 gallons per minute over a period of three days. The Discharger has evaluated the characteristics of the wastewater and determined that the wastewater is similar to the wastewater generated at Turner Road Vintners. The Discharger also evaluated the design of the wastewater treatment system and the capacity of the disposal system and concluded that the discharge of the additional wastewater will not impact the treatment system, exceed the capacity of the disposal system or conflict with any of the Discharge Specifications and Prohibitions in WDRs Order 99-103. While we appreciate the efforts to mitigate the impacts from the winter storms, staff cannot modify the conditions of an existing WDR. Therefore, the Discharger, Constellation Brands is performing the discharge at its own risk. Please document the discharge in Turner Road Vintner's Second Quarter 2017 Monitoring Report, which is due on 30 July 2017. As a reminder, we have transitioned to a paperless office. All documents including monitoring reports shall be converted to a searchable Portable Document Format (PDF) and submitted by email to centralvalleysacramento@waterboards.ca.gov The e-mail shall contain the following information: (a) Turner Road Vintners, (b) Title and Date of the Report, and (c) CIWQS Place ID No. 266743.
