<br />I <br /> <br />I <br /> <br />water in storage at Turquoise Lake, where we <br />have had the restriction of around forty-some <br />thousand acre-feet. <br /> <br />As the progress continues to improve on <br />Boustead Tunnel, the aggregate pile will no <br />longer be a problem to us. In fact, I could <br />say now that probably the aggregate pile is <br />no longer a problem to us." <br /> <br />MR. KROEGER: <br /> <br />"Are there any of the audience who would <br />like to ask Mr. Evans a question? Craig. " <br /> <br />MR. GOODWIN: <br /> <br />"I would like to ask him if he could <br />comment a little more on that mole thing. I <br />notice he got away from it rather fast. What <br />are your observations? Do you like it and is <br />it doing the job?" <br /> <br />MR. EVANS: <br /> <br />"The contractor, Peter Kiewit & Sons, <br />brought the mole in from Germany on an experi- <br />mental basis. They find, as a result of their <br />progress to date, that the mole works great in <br />stable rock conditions, but they are also <br />finding that where they encounter unstable <br />rock conditions that they are having problems <br />with the mole and it does impede progress. <br />Where they have been working in stable mater- <br />ial, they have made as much as five feet per <br />hour. Their maximum progress has been 67 <br />feet per day." <br /> <br />MR. GOODWIN: <br /> <br />"That I S in solid rock?" <br /> <br />MR. EVANS: <br /> <br />"In solid rock. yes. In unstable rock <br />they are having problems supporting the rock <br />in back of the cutter head until .the mole <br />can pass that unstable condition, which re- <br />quires about 30 to 35 feet of additional tunnel <br />excavation. " <br /> <br />MR. GOODWIN: <br /> <br />"Thank you." <br /> <br />MR. KROEGER: <br /> <br />"Are they in granite with some of this <br />stone that they are running into? Is there <br />any granite?" <br />
