Inspection of Fill <br />Horse Gulch Fill has been inspected for stability by a registered engineer or other qualified professional <br />specialist experienced in the construction of earth and rockfill embankments under the direction of a <br />qualified professional engineer. Inspections have been conducted at least quarterly throughout the <br />construction and during the removal of all organic material and topsoil, placement of the underdrainage <br />system where applicable, installation of surface drainage systems, placement and compaction of fill <br />materials and revegetation. <br />The qualified engineer has provided the Division a certified report within 2 weeks after each inspection <br />that the fill has been constructed as specified in the design approved by the Division. The report included <br />a description of any appearances of instability, structural weakness and other hazardous conditions <br />observed during the inspection. A copy of the report is maintained at the mine site. <br />Certified reports addressing the underdrain system and protective filters include color photographs taken <br />during and after construction, and before underdrains were covered with excess spoil. When the <br />underdrain system was constructed in phases, each phase was certified separately. Where excess <br />durable rock spoil was placed in single or multiple lifts such that the underdrain system was constructed <br />simultaneously with excess spoil placement by natural segregation of dumped materials, photographs <br />were taken of the underdrain as the underdrain was formed. The color photographs accompanying each <br />certified report were taken in adequate size and number with enough terrain or other physical features of <br />the site shown to provide relative scale to the photographs and to specifically and clearly identify the site. <br />` �:B94di 0e P}� '+•./ and <br />3-40b tltl-- <br />MAY 21 2013 oprovp - -- - -- - <br />
