Therefore,we will proceed with the installation <br /> of a dual casing extraction well on the northeast corner slope of the Secondary Site in accordance with the <br /> Remediation Plan submitted in November 2004. It is our understanding that the Plan has been approved, <br /> provided that neat cement slurry is placed between the upper collection section of the well installed in refuse <br /> and the lower collection section. To minimize condensate draining into the well,we will connect to the well <br /> with a lateral slope to drain to the header as shown in Figure 5 of the Plan. <br /> In moving forward with this work,we have visited the site with our drilling contractor,have contacted SCS <br /> for the installation of the lateral to the new well,and will be issuing Notice to Proceed to these firms shortly. <br /> The first activity by the driller will be to apply to your Department for a drilling permit. <br /> If you have any questions,please contact me at extension 8-3066. <br /> Sincerely, <br /> W.
