Box 22-11 <br /> Sacramento, CA 95812 <br /> SUBJECT: SPONSE TO PETITION, CHAPEV BROTHERS INVESTMENTS,INC., <br /> 1166 MONTE DIABLO AVENUE,STOCKTON,SAN JOAQUIN COUNTY <br /> Regional Botid staff reviewed the case file, including the 23 November 2004 Peliliun for Case Closure <br /> filed by Mr. . usseil Chapin(see attached memorandum for specific comments). Based on our review <br /> we concur with the San Joaquin Cotmty Environmental Health Department that significant contaminant <br /> mass and concentrations remain at the site and that a No Further Action Required letter should not be <br /> issued at this time. The Responsible Party has not adequately demonstrated that the plume will remain <br /> stable afterc ssation of active remediation by groundwater pump and treatment, that contaminant mass <br /> is reducing a the result of natural attenuation, nor properly projected when water quality objectives will <br /> be met. <br /> If you have gy questions please contact me at (916)464-4834 or Mr. James Barton at(916) 464-4615. <br /> APPROVED <br /> Brian Newm author <br /> Supervising Engincer UST Program Manager senior <br /> Enclosures <br /> Cc w/enc: TV r.
