Mr. Harlin Knoll, SJCEHD September 9, 2009 <br /> Addenduul to SCM and Environmental Case Closure,Request Project No. 2001-0103-07 <br /> A.Teichert and Sons,Inc.Property,Stockton,CA <br /> Page 3 <br /> PROPERTY OWNERSHIP <br /> Teichert and Land Company, P.O. Box 15002, Sacramento, CA 95851 owns the property <br /> at the subject site (San Joaquin County Parcel No.. 153-180-01). It is our understanding, <br /> based on conversations with Teichert personnel, that n6 liens or mortgages have been <br /> _ taken out on the property. <br /> CLOSURE REQUEST <br /> Based on the findings of this assessment-, we believe that completion of ftu-ther <br /> environmental activities at the subject site 'are not warranted, and that closure of this <br /> environmental case is appropriate. Although select fuel-related contaminants remain in <br /> groundwater beneath the site, available. data. suggests that concentrations of these <br /> contaminants will attenuate within a reasonable period of time. Strattis has previously <br /> reported that no groundwater sensitive receptors to the impact beneath the site-.are known <br /> (Site Conceptual Model„April 25, 2006); aid completion of additional site cleanup or <br /> assessment work does not appear justified. Stratus is therefore requesting that SJCEHD <br /> and RWQCB personnel consider closure of the environmental case for this site. <br /> If you have any questions or comments concerning the content of this report, or the site in <br /> general,please contact Jay Johnson at(530) 676-6000. <br /> Sincerely, <br /> 57_PA7-US ENVIKONM <br /> ArtjI WttG.Bit[inger -'t <br /> Scott G.
