Dept. of natural Resources <br />Transmitted herewith is our proposal for the engineering and surveying <br />for the data necessary for your reclamation plan on the existing <br />waste area and the proposal GEC Minerals prospect pit area. <br />SCOPE OF WORK <br />A. Dorchester existing waste area <br />1. Volume computations for the east end <br />a. fill area ( volume topsoil 12 in depth) <br />b. topsoil stock pile (c) <br />2. Refuge waste plan inclusive of east end <br />a. set elevation monuments <br />b. topography (existing) <br />c. cross sections <br />d. bases for location of soil compaction tests <br />e. locate tree area to be removed <br />f. set up elevation and section control <br />g. compaction tests <br />h. locate drainage ditches <br />i. locate ponds <br />3. Maps and plans <br />4. Engineering report pertaining to the east end addition <br />as per CMLRB regulations 4:10-4 1981 <br />5. Engineering report to address subsidence effect on old <br />underground workings as they pertain to east end add- <br />ition. <br />B. G.E.C. Minerals proposed waste area <br />1. Volume computations <br />a. fill area <br />b. topsoil stock piles (existing) <br />2. Set up elevations and section control <br />3. Set elevation monuments <br />4. Topography <br />5. Bases for location of soil compaction tests <br />6. Computations for over burden topsoil requirements <br />(Material provided by G.E.C.) <br />
