Kennedy/Jenks Consultants 1.4 Current Facility Operations BTQCLC is currently operating the Escalon Winery as a non-distilling, non-crushing, non- fermenting wine fining, stabilizing, and storage facility. Storage and processing of wine is similar to Canandaigua's historical operations. Fermented wine from other winery facilities is transported to BTQCLC for fining, stabilization and storage, and is then transported offsite for bottling and shipping. Refer to Kennedy/Jenks (2005a and 2005b) for a process flow diagram for current and proposed winery operations. BTQCLC plans to begin crushing operations at the Facility in 2007 and will gradually increase production by approximately 20% over five years until buildout in 2011. As part of the crushing operations, grapes will be delivered to the Facility crush area. From there, the must will be stored in fermenting tanks, pressed and filtered, stabilized, and then hauled to other facilities for bottling. As a result, what was known as the 'former crush area' will be reactivated and known as the 'new crush area.' BTQCLC uses rotary vacuum filters and pressure leaf litters for wine fining and filtering. These filters are rinsed with water after each fining/filtering event. An ion exchange system is currently used for wine stabilization. BTQCLC plans to continue these two processes and techniques in the future. As reported in the Pretreatment Report(Kennedy/Jenks 2004b) submitted to the CRWQCB on 27 September 2004, current wine storage was estimated at approximately 14.5 million gallons (MG). BTQCLC is currently in the process of adding 4.2 MG of storage with a plan to increase storage by approximately 4.2 MG per year for five years, compounding to an estimated total storage of approximately 37 MG. Used diatomaceous earth and pomace will be stored in a new staging area located in the northern portion of Basin 7. Improvements made within the winery have consisted of taking out of service, updating, and/or replacing equipment so that the Facility can continue to transition into primarily a wine storage facility. Recently, process water flow and quality have improved due to changes in operations concerning the cessation of distillation, or removal of equipment from service such as the ion exchange column, boilers, or water softeners. Since BTQCLC's purchase of the Facility in July 2003, one ion exchange column, two boilers, and all of the water softeners have already been taken out of service. Taking this equipment out of service has led to a reduction in the volume of wine ion exchange regenerate, water conditioning chemicals, boiler blowdown, and water softening regenerant discharged to the LAA. The strength of the discharge to the LAA has also declined. Approximately 10 million gallons (MG) of old, outdated wine storage tanks were removed. In addition, there are future plans to evaluate the use of pH neutralization chemical alternatives. Improvements that have been made to the process water collection system consist of routing both process water from the east sump and the north sump into the west sump, thus combining existing streams into one commingled stream (CRWQCB 2004). Historically, BTQCLC has used a spreading basin land application system consisting of evaporation and percolation basins for the treatment of process water, non-contact cooling water effluent, stormwater, and drainage from the rotary vacuum spent diatomaceous earth. Within each basin, a series of gates and checks has been operated for rotation and sequencing of process water applications. Between October 2003 and November 2004, combined process water discharge flow from the both the east and west sumps averaged approximately 4,252 gallons per day (gpd). Given these low flow volumes, BTQCLC developed a plan to complete a two-stage sump reconfiguration.
