Page 4 of 7 <br /> Regarding the pressure grouting of two well for this project—the drilling subcontractor <br /> recommend that we just over drill the two wells that were proposed to be pressure grouted. They <br /> feel the effort necessary to follow the mushroom capping procedure would take longer than just <br /> over drilling these shallow wells (TD=25'). Do you agree with is recommendation and if so, would <br /> you approve of over drilling these rather-than pressure grouting? E <br /> Please let me know and l will make the change to our permit application. <br /> I <br /> Thanks <br /> Gabe <br /> Gabe Stivala, P.G.I Senior Geologist I ATC Associates Inc.
