FACILITY, RIPON, SAN JOA QUIN COUNTY <br /> Central Valley Regional Water Quality Control Board staff(Regional Board staff) has reviewed the <br /> Draft 2004 Annual Groundwater Monitoring Report(Draft Annual Report)received on 31 March 2005. <br /> Regional Board staff comments on the Draft Annual Report and the current status of Nestle's remedial <br /> efforts are provided below. <br /> General Comments <br /> 1. The performance of the existing groundwater treatment plants (TPs) continues to be a problem. <br /> Nestle's recent record in monitoring the two TPs and avoiding breakthrough/discharge of volatile <br /> organics needs to be improved. The latest Draft Annual Report indicates breakthrough occurred in <br /> 4Q04 at the Stockton Avenue treatment plant and still hadn't been corrected by 2Q05 (see 1 Q05 <br /> Status Report). The new Monitoring and Reporting Program that will be issued to Nestle in the <br /> near future will include monitoring of treatment systems twice per month. <br /> 2. Even though Nestle was able to upgrade the Stockton Avenue TP and connect to the City of Ripon's <br /> non-potable water system in July 2004, the actual volume of water pumped and treated by the two <br /> treatment plants was well below our expectations. The Industrial Avenue TP treated less than 20 <br /> gpm and the Stockton Avenue TP treated approximately 350 gpm (approx 150 gpm below design <br /> capacity) during 4Q04. Some of the reasons provided for the lower than expected flows include <br /> maintaining water quality(primarily total dissolved solids) at a level that is acceptable for non- <br /> potable reuse and the high cost of discharging to the City's industrial sewer system. Nestle has had <br /> many years to develop treated groundwater disposal options and has had many conversations with <br /> Regional Board staff about the possibility that the City of Ripon might not be able to use Nestle's <br /> treated groundwater because of elevated inorganics or total dissolved solids (TDS). Nestle's <br /> progress towards developing viable disposal options for its treated groundwater needs to be <br /> accelerated. <br /> California Environmental Protection Agency <br /> Co Recycled Paper <br />
