As a result of <br /> this research,AGE recommended the advancement of several shallow hand-auger borings in the area <br /> of the former ASTs. <br /> On 25 March 2004, representatives of AGE proceeded to advance several shallow hand-auger <br /> borings in the assumed area of the former ASTs. As discussed in our telephone conference, it was <br /> our understanding that these"shallow"hand-auger borings did not have to be permitted as"formal' <br /> borings. However, after our telephone discussion and a review of the County well code, we <br /> recognize that permits are, in fact, required. Therefore, attached is a boring permit,permit fee and <br /> fee penalty(double permit fees). <br /> The scope of work performed included the advancement of four hand-auger borings,the deepest to <br /> a depth of approximately 8.5 feet. Field screening of soil removed from the borings was performed <br /> periodically using an organic vapor meter. Organic vapors were detected in the sample collected <br /> from the deepest boring(identified as 133).After advancement,each boring was then backfilled with <br /> native soil to surface grade. We then recommended a"formal' site assessment of the area; a work <br /> plan for a proposed site assessment has been submitted to your office. <br /> 837 Shaw Road,Stockton,California 95215 <br /> Telephone(209) 467-1006 FAX(209)467-1118 <br />
