All wells will need to be <br /> destroyed prior to the subsurface demolition. <br /> We plan to destroy all wells except MW-3,MW-9, MW-22 and the 17 ozone sparging wells <br /> prior to 15 January 2003. We plan to keep the ozone sparging system running as long as <br /> possible and close them just before subsurface demolition begins. Monitoring wells MW-3, <br /> MW-9 and MW-22 will be destroyed in February 2004, after another quarter of groundwater <br /> samples are collected. <br /> If you have any questions regarding this workplan please call. <br /> Sincerely yours, <br /> TREADWELL&ROLLO, INC. <br /> y�S'REDG. <br /> Q OhoA <br /> ti * No. 7066 <br /> David G.
