Box 1219 <br /> Lathrop, CA 951110 , <br /> CONDITIONAL APPROVAL OF GROUNDWATER MONITORING WORKPLAN, CALIFORNIA <br /> NATURAL PRODUCTS,LATHROP,SANJO.402IV COUNTY <br /> 1 have reviewed the 23 Pebruary 2003 Addendum Letter, Additional Monitoring Well Installations, <br /> California Natural Products, prepared by Kleinfelder. The plan was prepared in response to a <br /> 27 January 2004 Conditional Approval of Groundwater Monitoring Workplan. The workplan was <br /> originally prepared for Provision 0.2.b of Waste Discharge Requirements (WDRs) Order No, <br /> 1t5-2003-0141. After reviewing the addendum,I have the following comments: <br /> The addeadum states Well W-5 is located upgradient of the 10.1 acre land application area,but review <br /> of the contour maps provided in the addendum indicates,with the possible exception of the data <br /> collected on 11/19/03,that Well W-5 is downgradicnr of the 10.1 acre land application area. <br /> Kleinfelder's report fails to describe why the well should be considered upgradient. California Natural <br /> Products may tither select Well L-1 or a proposed well from the 29.7 acre land application area as ail <br /> upgradient well,provide justification for the use of Well W-5 as the upgradient well, or propose a new <br /> well installation. <br /> To complete the workplan,by 2 Ap;iil 2004 please submit a selection of one of the throe alternatives <br /> provided above. If you have any questions on this conditional approval,please telephone me at <br /> (916)464-4616. —� <br /> TIMOTHY . 0I"W <br /> Waste Discharge to Land Unit <br /> cc: Mike liuggins,San Joaquin County Ei Vironriiental T-Tcalth'Depaitrnent Stockton <br /> Robert Martin,Ylcinfelder, Stockton <br /> California Environmental Protection Agency <br /> g5 R&ya d Pop- . <br /> The energy obellcagc racing Califomia is real.
