The'plan was prepared in response <br /> to a 3 March 2004 Conditional Approval of Groundwater Monitoring Workplan. The workplan was <br /> originally required by Provision 6.2.b of Waste Discharge Requrremeats (WDRs) Order No. <br /> R5-2003-0141. <br /> Addendum No. 2 requests authorization to install three monitoring wells in the 29.7 acre land <br /> application area and install a fourth new well in a different location, at:�a later date. The fourth well <br /> will provide background information for the 10.1 acre land applicatiol area but cannot be installed <br /> until an access agreement can be obtained from the landowner that owns the property where the well <br /> will be located. Two possible locations for the new fourth well are presented in the Addendum. <br /> Califoulia Natural Products (CNP) wants to begin discharging at the 29.7 acre land area before the <br /> access agreement can be,finalized. The Addendum presents a til ac schedule for obtaining the access <br /> agreements. <br /> The work proposed in Addendum No. 2 is acceptable. CNP may install the wells at the 29.7 acre land <br /> area immediately. However, the proposed fourth well location(two potential locations are presented in <br /> the Addendum) may not be adequately located to establish upgradient groundwater conditions for the <br /> 10.1 acre land application area. By 7 May 2004, CNP shall submit a Hydrogeologic Evaluation of <br /> Groundwater Conditions (I GC)that supports the proposed fourth well location. The FMGC shall <br /> include an implementation schedule for installation of the fourth'well. <br /> If you have any questions on this conditional approval,please telephone me at(916) 464.-4616, <br /> TIMOT R.
