Ms. Camille Farrell <br /> March 15, 1989 <br /> Page 2 <br /> ANNUAL REPORT (continued) : <br /> (2) Terry Tunnel Area: <br /> The sludge placed in pits along the east end of the mine <br /> bench was excavated and transported to Tailings Pond #3 . <br /> The pits were eliminated by filling with material from the <br /> outside berm of the pits . The vegetative test plot <br /> mentioned in the annual report was not established as <br /> recommended by the Division. <br /> Monitoring Results January, 1987 to March , 1987: <br /> (3) At this time, I cannot explain why Boulder Creek was <br /> eliminated from the 1988 monitoring schedule. We missed the <br /> April sample because of this , but did taken an October , 1988 <br /> sample. If sample sites are to be eliminated in the future, <br /> we will discuss the issue with the Division before changing <br /> the monitoring schedule. <br /> Surface Water : <br /> (4) SCTP3-1 is the upstream site on the north side of <br /> Highway 110 , and SCTP3-2 is downstream on the south side of <br /> Highway 110 before entry into the Animas River. <br /> Changes to Monitoring Program for 1988 : <br /> (5) The American Tunnel waste dump seeps that were being <br /> monitored have been covered by expansion of the waste dump. <br /> An effort was made to sample along the toe of the waste dump <br /> in October , 1988 , but no seeps or springs could be found for <br /> sample collection . Possibly this was due to dry weather <br /> conditions at the time, and we will try to sample again this <br /> spring. Monitorinq of water exiting the American Tunnel <br /> waste dump will be addressed in the technical revision <br /> submittal . <br /> AMENDMENT NO. 3 STIPULATION COMPLIANCE INFORMATION: <br /> (1 ) Enclosed is an open pit slope stability analysis by J.F. T. <br /> Agapito & Associates, Inc. The size of the open pits was <br /> significantly reduced from those proposed in Amendment <br /> No. 3 . The attached study covers approximately two-thirds <br /> of the work on the Sunnyside Pit. Please advise me after <br /> reading this report if you want a final stability report <br /> prepared this spring or early summer . Agapito & Associates <br /> inspected the Washington Pit, but at that time there was not <br /> enough exposure to make an analysis . <br />
