Included in <br />the revised Exhibit are sheets depicting the existing and revised plans and profiles for the area, as well as the <br />reclamation plan and sections. <br />This technical revision would not result in an increase of disturbed area, as these additions replace the <br />presedimentation basins and sludge drying lagoons previously approved (per TR 83) at this location. A <br />spreadsheet has been provided that includes the estimated excavation volumes, pipe lengths, geotextile and liner <br />square footage, new fence length, and concrete volumes. Using these values, MCC would appreciate the <br />Division's assistance in providing reclamation estimates and associated bond readjustment calculations. <br />Please contact me at (970)929-2238 or by e-mail should you have questions regarding this submittal. <br />Sincerely, <br />VV <br />Kath een G.
