~•C <br /> <br /> <br />MEMO <br />DATE: February 2, 1993 <br />TO: Marcus Middleton ~/~~ <br />FROM: Collin Stewart <br />SUBJECT: Inspection of Leakage, Site 115, Fish Creek Borehole Settling Ponds <br />My observations indicate that the leakage that presently occurs through the berm at the settling pond <br />site does not pose any hazard to the integrity of the berm at this time. Further, should failure oC the <br />berm occur, a review of the surface topography indicates that any out Row will be contained within <br />the topographic basin that occurs immediately below the pond site. Therefore, the worst case will not <br />result in any significant damage to persons or properly. <br />After reviewing the leakage at the settling ponds, 1 agree with your assessment that there is probably a <br />break in the inlet or discharge line buried in the dam. I recommend the repair be made in the <br />summer, when site conditions are conducive to the best possible work. <br />In the interim, I recommend the following course of action: <br />1. Perform weekly inspections of the berm. This inspection should be performed by the same <br />person or persons. The inspection specifically will note any changes: <br />(a) in the condition of the berm; <br />(b) in the extent of the soggy area along the top of the berm; <br />(c) in the amount of seepage; <br />(d) in the extent of the seepage; and, <br />(e) in the color of the seepage water. <br />2. If any of these changes occur, re-evaluate the stability of the structure and develop a new <br />action plan. <br />cc: Rick Mills <br />Terry Ritzel <br />
