The workplan was prepared in response to Provision G.2.e of <br /> Waste Discharge Requirements (WDRs) Order No. R5-2002-0225. After reviewing the workplan,I have <br /> the following comments: <br /> • The 20-foot screen length is too long;please limit the screen length to no more than 15-feet. It should <br /> be noted that monitoring the air/groundwater surface is not required at this site because floating non- <br /> aqueous phase substances are not anticipated to be present. Therefore,the screened interval can be <br /> placed slightly below the water table to minimize the possibility of the well going dry during late <br /> summer months. <br /> • If a slip cap is used on the bottom of the well casing, it must be secured using stainless steel screws. <br /> • Please include an evaluation of the adequacy of the groundwater monitoring network. In July 2002, <br /> Wells MW-1 and MW-4 went dry and could not be sampled. If the wells cannot be used to monitor <br /> groundwater quality propose replacement of the wells. <br /> Please respond to the comments in this conditional approval no later than 30 May 2003. If you have any <br /> questions on this conditional approval,please telephone me at(916) 255-3116. <br /> TIMOT R.
