South Ta for Fill Inspection Certification <br /> On dune 401, 2019 I inspected the South Taylor Fill areas, which includes the East Taylor Fill <br /> and the West Taylor Fill, identified on Map 23A and Map 45 of the approved permit. The <br /> purpose of this inspection was to observe the status of the fill placement. This inspection is <br /> necessary to satisfy the requirements of CDRMS Rule 4.09.1(1)(c) and Rule 4.09.1(11). <br /> Weather conditions at the time of inspection were approximately 60*F and sunny. <br /> West Taylor Fill with A-A' and B-B' Underdrain Area No new activity has occurred within the <br /> permanent Vilest Taylor Fill since last inspection. The East Tributary of the Vilest Taylor fill has <br /> been rip-rapped up to the 7850' elevation (approximately). The West Tributary of the West <br /> Taylor fill has been rip-rapped up to the 7820' elevation. Dumping has ceased on the 8100' level <br /> of the temporary out of pit stockpile. <br /> The current water level reading of the piezometer well was 201.2' from the ground surface, an <br /> increase in water level of 15.8' from the previous quarter. The West Taylor Fill underdrain was <br /> freely flowing at the time of inspection. <br /> No structural weakness, signs of instability, or other hazards were noted at the time of <br /> inspection. <br /> East Taylor Fill with C-Cl Underdrain Area: No activity other than rock crusher operations <br /> have taken place within the East Taylor fill during this quarter. <br /> No structural weakness, signs of instability, or other hazards were noted at the time of <br /> inspection. <br /> Design requirements for the spoil pile are addressed in Volume 13, Exhibit 21, Item 1, <br /> Introductory Letter. Inspection requirements during construction are further detaiied in Volume <br /> 12, Section 4.09. <br /> 1 am a Registered Professional Engineer in the State of Colorado.
