Inspection of Fill <br />Horse Gulch Fill will be 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 at least quarterly throughout the construction and during the removal of all <br />organic material and topsoil, placement of the underdrainage system where applicable, installation of <br />surface drainage systems, placement and compaction of fill materials and revegatation. <br />The qualified engineer will provide the Division a certified report within 2 weeks after each inspection that <br />the fill has been constructed as specified in the design approved by the Division. The report will include a <br />description of any appearances of instability, structural weakness and other hazardous conditions <br />observed during the inspection. A copy of the report will be maintained at the mine site. <br />Certified reports addressing the underdrain system and protective filters will include color photographs <br />taken during and after construction, but before underdrains are covered with excess spoil. If the <br />underdrain system is constructed in phases, each phase will be certified separately. Where excess <br />durable rock spoil is placed in single or multiple lifts such that the underdrain system is constructed <br />simultaneously with excess spoil placement by natural segregation of dumped materials, photographs will <br />be taken of the underdrain as the underdrain is being formed. The color photographs accompanying each <br />certified report shall be taken in adequate size and number with enough terrain or other physical features <br />of the site shown to provide relative scale to the photographs and to specifically and dearly identify the <br />site. <br />3-40b <br />'?R 106 <br />611L)2,016 <br />
