Messrs. Calvin and Cran <br /> 00 23 May 2008 <br /> uptake capacity. Staffs concern about the loading rate and need for additional source <br /> control were also discussed in the meeting. <br /> 4. The proposed improvements will not reduce the FDS concentrations in a significant way. <br /> Water Treatment Evaluation Report, prepared by Kennedy/Jenks <br /> Staff pointed out that the 1 March 2006 Process Water Characterization and Process <br /> m. In our <br /> waste streams and calculated the percent of the total load per wadescribed individual <br /> ste strea <br /> meeting, staff noted that water softening activities contribute 23-percent a the total FDS <br /> load and only generate 253,8585 gallons (0.31-percent) of the total 82 million gallon <br /> wastewater flow. Based on the information presented in the report, it appears a <br /> significant reduction in FDS loading rate is possible by segregating that waste stream <br /> and disposing it in an alternative manner. <br /> 5. The plan to install three lined aeration ponds raises some additional issues. The <br /> workplan describes, and in our meeting we discussed, a system to separate the dilute <br /> stormwater flows from winery wastewater. The following concerns have been identified: <br /> a. How much will the new ponds evapoconcentrate FDS? <br /> b. The size of the ponds may reduce the size of the land application area available, <br /> increasing the FDS loading rates. <br /> 6. The wine truck wash down activities described in the Workplan were previously unknown <br /> to staff. Please provide a better description of the activities. For example: are tank <br /> trailers cleaned at the facility? Is the cleaning a simple rinse out using tap water, or is it a <br /> thorough cleaning using acids, caustic, and/or disinfection chemicals? <br /> As described above, staff remains concerned about the FDS loading rate of the land <br /> application areas. If you have any questions on this Workplan review please telephone Tim <br /> O'Brien at (916) 464-4616 or me at (916) 464-4732. <br /> MARY SERRA, P.E., Chief <br /> WASTE DISCHARGE TO LAND UNIT <br /> cc: Mike Huggins, San Joaquin County Environmental Health Department, Stockton <br /> Robert Chrobak, P.E., Kennedy/Jenks Consultants, San Francisco <br /> W:\Sufl\ObnanTSan JoaquirV Mondavi\Calvin 20 Mar 08.doc <br />
