The <br /> workplan describes plans to install six pan lysimeters and four groundwater monitoring wells. However, <br /> only one of the four wells is proposed for immediate installation; no schedule is presented for the <br /> remaining wells. The workplan was prepared in response to Waste Discharge Requirements (WDRs) <br /> Order No. R5-2002-0148, Provision G.2.b. <br /> Musco Family Olive Company shall submit an addendum to the workplan that addresses the following <br /> comments: <br /> • The scope of work in Section 3 includes an incomplete quote of the requirements in WDRs <br /> Provision G.2.b and the work described in the workplan does not fully address the requirements of <br /> Provision G.2.b. <br /> • The workplan fails to present the locations of the groundwater monitoring wells to be installed <br /> upgradient and downgradient of the 84-Mgal storage pond. On 22 October 2002, staff provided <br /> conditional approval of a 26 September 2002 Kleinfelder workplan to install the wells. Please revise <br /> the workplan plates to accurately present the location of all proposed and existing monitoring <br /> locations. <br /> • Section 2.4 of the workplan discusses soil borings previously drilled at the facility but does not <br /> provide the soil boring locations on the plates. Please include a plate that shows all the soil borings <br /> that are described in the workplan. <br /> • The workplan does not include a schedule for replacement of the wells that have gone dry after <br /> installation. Please provide a schedule for the replacement of the wells or a discussion as to why <br /> replacement wells are not needed. <br /> • The workplan does not include a schedule for installation of the three wells that will be drilled near <br /> Wells MW-1, MW-2, and MW-6. Please provide a schedule for the well installations. <br /> California Environmental Protection Agency <br /> ra Recycled Paper <br /> The energy challenge facing California is real.
