Mr. W. T. Nickerson 0 - 2 - • 31 October 2000 <br /> discharge option are also the disposal options that are most readily implemented. Either of these <br /> disposal options will require acceptance of the purge water by the respective authorities. <br /> The Work Plan is approved subject to the condition that proof of acceptance of the purge water be <br /> conveyed to Board staff. <br /> Thank you for incorporating a pilot test of groundwater treatment into the aquifer testing element. This <br /> is the most economically efficient time to assess whether air stripping and/or carbon adsorption is <br /> effective with the constituents of concern at this site, and also provides the data necessary to evaluate <br /> longer term groundwater disposal options. <br /> A report of the results of the aquifer testing work plan is due by 19 January 2001, which is about 90 <br /> days after UNOCAL obtained an access agreement, as proposed in Sierra-Pacific Group's 30 March <br /> 2000 Schedule for Completion of Aquifer Testing letter. <br /> If y, have any `uestions you may contact me at(916) 255-3080. <br /> AMY TE LL <br /> Site Cleanup Unit <br /> enclosure <br /> cc: Mr. Michael Infuma, San Joaquin County Public Health Services (without encl.) <br /> Mr. Jan Wagoner,UNOCAL West Sacramento (without encl.) <br /> Mr. Anthony Giglio, Stockton(without encl.) <br /> Mr. Eric Chase, Sierra-Pacific Group, El Dorado Hills (with encl.) <br />
