Regional Board staff was alerted to the existence of the workplan by San <br /> Joaquin County Environmental Health staff when processing Well Construction Permits. The plan was <br /> prepared to characterize groundwater elevation and quality for the Report of Waste Discharge(R)ArD)in <br /> preparation for the City of Lathrop's Membrane Bioreactor(MBR)wastewater treatment system. <br /> The Introduction section of the workplan states only two of the three wells will be sampled for chemical <br /> analysis. This may not adequately characterize groundwater conditions of the site. Because groundwater <br /> flow direction is not known, and is suspected of being altered based on local groundwater extraction or <br /> other activities, limiting the number of wells sampled is not acceptable at this time. Regional Board <br /> staff strongly recommends all three wells be sampled to prevent delays in processing the RWD when it <br /> is submitted. <br /> To complete the workplan,by 2 April 2004 please submit an addendum that either supports the limited <br /> sampling as adequate to characterize groundwater quality, or provide a statement that all three wells will <br /> be sampled. If you have any questions on this conditional approval,please telephone me at (916)464- <br /> 4616. <br /> 1-15 <br /> TIMOTHY O'BRIEN <br /> Waste Discharge to Land Unit <br /> cc: Mike Huggins, San Joaquin County Environmental Health Department, Stockton <br /> Doug Heard, Kleinfelder, Stockton <br /> Kevin Kennedy,HDR,Folsom <br /> California Environmental Protection Agency <br /> 01 Recycled Paper <br /> W:�Sua`9brimTSm)oa9uivlaWop_W WTP`I.160.Phau f�BeJnc 29 Ma Ol.doc <br />
