r Mike Owens Fox River Paper Company 2 San Joaquin County in the City of Ripon well MW-9, it appears that the Mill site is impacting this intermediate-aquifer municipal well. In this regard, we are concerned with the water quality of MW-9, as a City of Ripon municipal well. The California Secondary Maximum Contaminant Limit(MCL) for TDS is 500 mg/L. The latest data on MW- 9 reports TDS at 530 mg/L in June 29, 2000. Other City of Ripon municipals wells show TDS ranging between 360-490 mg/L. It is not evident whether the City of Ripon Department of Public Works is aware of this situation even though I'm sure they closely monitor the water quality in their City wells. Board staff did not find a statement determining"...whether or not the existing discharge is having a negative impact on the local water quality." (WDR Prov.G.7.b.) Please submit by 1 July 2003 amakes this determination based upon the n addendum to the Five-Year Report, in the form of a letter, which analysis provided in the Five Year Report. Plea,,e copy this letter/addendum to the City of Ripon Public Works Director. 3. Actions Taken to Reduce Dissolved Solids: Effluent TDS has been reduced by actions taken over the five- year period by Fox River. Overall, TDS concentrations for effluent water have decreased. Thus, changes in mill processes appear to have had a positive effect on effluent water quality. Yet, there continues to be increases in TDS around the site. It is not clear whether some of the increases are caused by the City of Ripon Sewage Ponds adjacent to the western boundary of the property where TDS ranges between 700 and 910 mg/1. Board staff have contacted City of Ripon Public Works Department to discuss this issue in more detail with regards to their monitoring wells surrounding the Sewage Ponds. We are also discussing the TDS issue at the northeastern corner of the Fox River site with Board staff working on the Nestle facility clean up. Most recently, a sludge pond has been closed with Regional Board oversight. By this action, water quality may also show improvement over time. WDRs do not require the Five-Year Report provide a discussion of further corrective action measures planned to reduce constituents of concern in groundwater. The following discussion shall provide guidance in this regard. Annual Monitoring Report and Corrective Action Monitoring and Reporting Program(MRP) section of the WDRs states, "Upon written request of the Board, the Discharger shall submit a report to the Board by 30 January of each year. The report shall contain both tabular and graphical summaries of the monitoring data obtained during the previous year. In addition, the Discharger shall discuss the compliance record and the corrective actions taken or planned that may be needed to bring the discharge into full compliance with the waste discharge requirements." By this letter, we are formally requesting that you submit the annual reports by 30 January of every year starting in January 2004. The purpose of this request is to ensure that there is a complete analysis of the lateral and vertical extent of the plume(s) and the necessary corrective actions taken or planned to mitigate increases in constituents of concern. As specified in the MRP, the annual reports should include Water Supply Monitoring for Standard Minerals, Electrical Conductivity @ 25°C, and total dissolved solids. Plant Effluent Monitoring should include Standard
