<br /> Dear Ms. McKenna:
<br /> The San Joaquin County Environmental Health Department (EHD) is extending the date for
<br /> completing the fieldwork at the above-referenced subject site from 19 December 2010, to 31
<br /> March 2011. Mr. Eli Scott of Holguin, Fahan, & Associates, Inc. requested the extension by
<br /> e-mail dated 17 December 2010, since weather conditions have made the current site
<br /> conditions difficult and dangerous to complete the fieldwork that includes:
<br /> • Advancement of cone penetration test (CPT) boring CPT-10 if hole clearance to eight
<br /> feet below surface grade is successful;
<br /> • Advancement of soil borings adjacent to CPT-7, CPT-9 and proposed CPT-10 for the
<br /> collection of grab groundwater samples at discreet depths; and
<br /> • Advancement of soil borings adjacent to CPT-7, CPT-9 and proposed CPT-10 for the
<br /> collection of soil samples at discreet depths.
<br /> If you have any questions or concerns regarding this letter, please contact Vicki McCartney at
<br /> (209)468-9852, or by email at vmccartney@sjcehd.com.
<br /> Sincerely,
<br /> Victoria L. McCartney, REHS Nuel C. Henderson, Jr., PG
