If we were <br /> provided a copy of that I cannot find it. I would like to be able show the originaF sample locations and results <br /> along with the new sample locations and results when we report the data. Would you please 2provide a copy (fax <br /> or PDF by email) of that sketch and any other measurements that may indicate,original sample location based <br /> any reference points e.g. (sign post near UST pit) (x-feet from dispenser). <br /> was very successful in getting great before and after pictures of the UST and piping run to the fuel island. I am <br /> creating scale from the building known dimensions and recreating the former; island, pipeline trench patch, and <br /> UST tank pad with fill buckets shown (see attachments). If we can get real close to recreating those locations, I. <br /> may request you allow the elimination of ground penetrating radar or we could significantly reduce covering what <br /> was originally viewed as making passes over almost 112 acre to find the pit and trench. Now I could confirm those <br /> locations with short passes on 5-foot centers, based upon the aerial pictures clarity. <br /> Still working on schedule and permit inspection fees with City, while I do some advance work to then call in USA <br /> for utility location work. <br /> John <br /> .
