VALPICO <br /> ' ROAD, TRACY, SAN JOAQUIN COUNTY <br /> Georgia-Pacific Corporation (Georgia-Pacific) formerly operated chemical packaging plant at <br /> ' 75 W. Valpico Road in Tracy (Site). Site activities resulted in chloroform contamination in soil <br /> and groundwater. <br /> As the attached Memo to Antonia Vorster, the Site Cleanup Program Manager indicates, <br /> Georgia-Pacific excavated soil, pumped and treated groundwater, and used an in situ ozone <br /> sparge system to remove the chloroform from the site soil and groundwater. The Regional <br /> ' Water Board concurs with Georgia-Pacific that the remaining levels of chloroform do not pose <br /> a threat to human health, the environment, or waters of the State. <br /> On 4 January 2011 Regional Water Board staff sent a fact sheet describing the cleanup <br /> ' actions and notifying interested persons of their opportunity to provide comments on the 14 <br /> May 2009 Report on Additional Investigations in Support of Site Closure. No comments were <br /> received during the 30-day time period. <br /> Georgia-Pacific has satisfactorily completed site investigation and remedial action, <br /> achieved applicable remedial action standards and objectives, and a permanent remedy <br /> ' has been accomplished at 75 W. Valpico Road in Tracy. Therefore, no further action is <br /> required. This No Further Action Determination is not effective until after Georgia-Pacific <br /> submits the necessary documentation of the destruction of the site monitoring wells, in <br /> ' accordance with all applicable County and State requirements. Once proof of appropriate <br /> destruction has been received, Water Board staff will send written confirmation of the <br /> effective date of this Determination. By 1 June 2011, please submit a work plan under <br /> ' which the monitoring wells at the site will be destroyed. <br /> Issuance of a No Further Action Determination does not preclude future action by the <br /> ' Water Board if subsequent monitoring, testing, or analysis of 75 W.
