CLEANUP AND ABATEMENWER NO. <br /> ROBERT MONDAVI CORPORATION 5 <br /> ROBERT MONDAVI WINERY <br /> SAN JOAQUIN COUNTY <br /> and wastewater management plans, as well as systems that will Protect underlyingDRAFT <br /> groundwater from degradation by the discharge of process wastewater. The workplan <br /> shall detail the location at which samples will be collected, sampling frequency, and <br /> constituents to be analyzed. <br /> b. A Wastewater Treatment and Disposal System Evaluation Workplan that describes the <br /> sampling, analytical activities, and evaluation of the existing process wastewater <br /> treatment, disposal, irrigation systems and management plans. The plan shall address <br /> those activities necessary to evaluate the treatment capabilities of the facultative pond <br /> treatment system, the treatment and disposal potential of vineyard disposal area and <br /> irrigation system, and any other treatment and disposal processes that could have a <br /> significant influence on wastewater and groundwater quality. The purpose of this study <br /> will be to provide the information necessary to define system capacities and limitations, <br /> and to identify and comprehensively evaluate potential upgrades and improvements to <br /> existing treatment and disposal management plans and systems that will protect <br /> underlying groundwater from degradation by the discharge of process wastewater. The <br /> workplan shall detail the location at which samples will be collected, sampling frequency, <br /> and constituents to be analyzed. <br /> c. A Groundwater Characterization Workplan that describes a plan to fully evaluate the <br /> hydrogeology and water quality of shallow groundwater underlying the facility, the <br /> relationship between the river and underlying shallow groundwater, the impact of <br /> historical process wastewater discharge and other discharge practices on underlying <br /> shallow groundwater, and the potential impacts of future wastewater discharges on <br /> underlying shallow groundwater. If the workplan proposes to use existing domestic, <br /> irrigation, or off-site monitoring wells, then the workplan shall clearly demonstrate why <br /> the proposed wells should be used as part of the groundwater monitoring network, <br /> provide well construction details (well logs, as-builts, down-hole investigations) for <br /> proposed wells, describe when and how the well is pumped, and clearly justify why the <br /> proposed well(s) is preferential to a dedicated monitoring well. The workplan shall <br /> clearly identify the wells to be sampled, sampling frequency, and constituents to be <br /> analyzed. The need for installation of additional monitoring wells shall be considered <br /> and discussed in detail. If the installation of additional monitoring wells is found to be <br /> necessary, the Groundwater Characterization Workplan shall include a Groundwater <br /> Well Installation Workplan that describes the installation of additional properly located <br /> monitoring wells to fully assess the potential impacts of future process wastewater <br /> discharge on underlying groundwater. The Groundwater Well Installation Workplan <br /> shall be prepared in accordance with, and shall include the items listed in, Section 1 of <br /> Attachment A:Requirements for Monitoring Well Installation Workplan and Monitoring <br /> Well Installation Reports. <br /> 3. If the Groundwater Characterization Workplan included a Groundwater Well Installation <br /> Workplan, then by 1 March 2005, Robert Mondavi Corporation shall submit a Monitoring Well <br /> Installation Report that contains the information described in Section 2 of Attachment A. <br />
