Kevin D. Sterling - 2 - `/ 14 July 2004 <br /> • The workplan does not specify the borehole and well casing diameters. Because a minimum of <br /> two inches of annular space must exist around the well casing, if a nominally two-inch well <br /> casing is installed, the boring must be eight inches in diameter, and if a nominally four-inch <br /> diameter well casing is installed, the boring must be ten inches in diameter. <br /> Process Water Characterization Work Plan <br /> • This workplan does not clearly identify the methods for quantifying the volume of wastewater <br /> contributed by the various process water source systems. The workplan suggests that many of <br /> various system flow volumes may be estimated. However, this may not provide adequate data to <br /> fulfill the purpose of this study. An extremely important part of the study will be the <br /> quantification of the wastewater volumes contributed by the various systems. Therefore,prior to <br /> initiating this study, additional consideration must be given to implementing the best practicable <br /> methods available, including the installation of additional flow meters, for quantifying flow from <br /> the specific systems. Once specific quantification methods are chosen,they should be described <br /> in detail in a quarterly progress report prior to their implementation <br /> If you have any questions regarding the contents of this letter,please contact Jim Martin at <br /> (916) 464-4685. <br /> THOMAS R.
