CmcCONTINENTAL MATERIALS CORPORATION <br /> figures at this time as this level of detail will be based on field observations during the execution <br /> of the Plan. As these roads are required, CMC will submit a Technical Revision to incorporate <br /> new facilities showing the location and size (width and length) of each road into the Mining Plan. <br /> The roads will all be constructed within previously disturbed areas. <br /> The acreage and cut and fill volumes for each area are included in Table D-2. <br /> Table D-2 <br /> Areas of Cut and Fills <br /> Area Cut Volume Fill Volume <br /> Grading Area s <br /> (acres) (BCY ) (LCY ) <br /> Backfill 42.9 na 3,985,558 <br /> Upper slope 21.1 609,952 na <br /> Lower quarry (various areas) 75.1 2,711,346 na <br /> Total 139.1 3,321,298 3,985,558 <br /> Notes: <br /> 1.

Topsoil needed is 112,000 LCY <br /> (c) Water Diversions and Impoundments <br /> Storm water from all areas of disturbance will be directed into the existing sedimentation systems <br /> for the mine throughout reclamation activities. After the water is clarified it will be discharged into <br /> existing drainages. A Colorado Discharge Permit System (CDPS) discharge permit for the current <br /> operations already exists and will be maintained through the life of the operation. <br /> The reclamation drainage will be constructed as the site is reclaimed, and this drainage network <br /> is discussed in Exhibit G. <br /> (d) Size of area(s) to be worked on at any one time <br /> Consistent with previous amendments, the affected lands boundary at the Pikeview Quarry <br /> coincides with the permit boundary as shown on the maps in Exhibit C. Grading may occur in <br /> any portion of the 240.5 acres of the quarry permit area throughout the life of the project. Once <br /> an area is graded to the reclamation topography, it will be topsoiled and seeded for final <br /> reclamation. <br /> (e) Timetables for Mining and Reclamation Operations <br /> Pikeview Quarry Amendment 4 <br /> D-6 <br />
