INTEROFFICE CORRESPONDENCE <br /> Date : January 19 , 1988 <br /> • 4 <br /> To : John Turner <br /> From: Scott Jones <br /> Subject : Sedimentation Pond Inspection , First Quarter 1988 <br /> On January 18 , 1988 an inspection was made of all Mid- <br /> Coi)tinent Resources , Inc. sedimentation ponds in Coal Basin and <br /> at the loadout in Carbondale . <br /> The purpose of this inspection was to ensure that all of the <br /> ponds were stable and hazard free and to satisfy the requirements <br /> of Rule 4 . 05 . 6 ( 11 ) ' c ) and 4 . 05 . 9 ( 10 ) ( 6) of the Colorado Mined <br /> Lsnd Reclamation Division . The inspection consisted of a visual <br /> inspection of embankments , spillways and outlets and a <br /> measurement of water and sediment levels and discharge volumes . <br /> hater levels are based on past survey information . Sedimentation <br /> levels were based on a prodding stick and knowledge of the last <br /> r 1 �-:in--out date for each pond . <br /> Heavy January snows along with thick ice made most <br /> observations very difficult . None of the ponds at #3 , #4 and #5 <br /> Mines were inspected because the roads were not open . The ponds <br /> that were accessible appeared to be in good shape. A detailed <br /> check list for the ponds inspected is attached to this memo . <br /> Scott Jones , P. E . <br />
