The results of analytical testing of discrete soil and discrete <br /> ground water samples from the CPT borings should provide sufficient data to define the lateral <br /> and vertical extent of impact around the RIW. These data in turn will be used to detern ine what <br /> additional work is required to determine the vertical extent of ground water impact be ieath the <br /> Wards and Unocal sites. <br /> Cleanup and Abatement Order No. 5-00-707 (CAO), page 5, item 9, requires th a Final <br /> Remediation Plan for the cleanup of soil and ground water at the former Unocal site be ubmitted <br /> by December 1, 2000. Analytical data from the CPT borings will not be available until the week <br /> of November 27, 2000, and these data must be reviewed and evaluated to determine what <br /> additional work is required at the Unocal site, before a Remediation Plan for the Unocal site can <br /> be prepared. Therefore, it is requested that the date for submittal of the Remediation Plan for the <br /> Unocal site be extended to February 15, 2001. <br /> The CAO, page 6, item 10, also requires the construction and operation of a remedial ystem on <br /> the Unocal site by January 26, 2001. For the same reasons listed above, we are requ sting that <br /> this date be extended to April 15, 2001. <br /> PLANNING,ENVIRONMENTAL ANALYSES AND <br /> HAZARDOUS SUBSTANCES MANAGEMENT AND REMEDIATION <br />
