The <br /> on-site deep monitoring well was also approved in the 24 September letter. <br /> Horizon submitted a work plan to EHD on 12 February 2008 for 3 on-site vapor wells. Horizon would like to install <br /> these wells during the same mobilization as the monitoring wells. When can we expect your approval of the <br /> vapor well work plan? The vapor extraction system is shut off pending installation and hookup of the proposed <br /> vapor wells. <br /> Horizon is submitting permit applications (see attached)today for the 4 monitoring wells and the 3 vapor wells. <br /> The fieldwork/drilling is currently scheduled for March 24-26 2008 in accordance with your directive in the 31 <br /> December 2007 letter. This drilling date is a week from Monday next. <br /> Please inform Horizon of the results of your vapor well work plan review and advise Horizon if the drilling <br /> schedule can be kept. <br /> Rexford Smith <br /> Professional Geologist No. 5307 <br /> HORIZON ENVIRONMENTAL INC. <br /> 4970 Windplay Drive, Suite 5 <br /> El Dorado Hills, California 95762 <br /> (916)939-2170 <br /> (916)939-2172 FAX <br /> 3/12/2008 <br />
