CWI would construct water spray bars or a baghouse at this truck dump and
<br />short COnV eyOr,
<br />The reyular periodic maintenance of the short conveyor would require inspec-
<br />Lion by light-truck vehicles on a daily basis. The short conveyor would be
<br />repaired and lubricated as required, The truck dump would be continually
<br />manned. Maintenance would continue on an as required basis, The light
<br />truck would access the conveyor on yraveled light-use roads.
<br />At the current production rate, ten truck drivers are employed for trans-
<br />porting of coal at the Orchard Valley Mine. With increased production,
<br />additional truck drivers would be employed, Initially, with construction of
<br />the truck dump and short conveyor, no change would be made to the number of
<br />truck driver employees, Upon operation of the truck dump and short con-
<br />veyor, part of the truck drivers would be laid off, CWI expects three addi-
<br />tional employees would need to be hired to operate and maintain the truck
<br />dump and short conveyor,
<br />Reclamation
<br />After the Orchard Valley Mine had ceased operations, the truck dump, stock-
<br />piliny facilities, and short conveyor would be dismantled and salvaged for
<br />possible resale. The steel support structures, foundations, and fencing
<br />would also be removed and the sites backfilled to approximate original con-
<br />tour, Stored topsoil would be distributed over the site as approved in the
<br />Orchard Valley Mine existing reclamation plan.
<br />Gravel would be stripped from the light-use roads and the roads scarified,
<br />Water bars would be constructed to control drainage and the road seeded,
<br />The truck dump site would also be regraded, topsoil redistributed, and
<br />reveyetated, The trench would be backfilled with the previously stockpiled
<br />subsoil, topsoil redistributed, and the site revegetated, The haulage road
<br />would be reyraded, topsoil redistributed, and revegetated, Reclamation
<br />activities would last fora short period of time, see Figure ~2,
<br />The light-use road and at-grade conveyor sites on alluvial agricultural
<br />lands would be reyraded, topsoil redistributed, and irrigation patterns
<br />restored. Pasture, orchard, or other appropria~e vegetation would be
<br />replanted on these sites, The specific procedure for reclamation of this
<br />area would be the same as for the existing storage and loadout facility,
<br />refer to Appendix "M" for the procedure, All essential hydrologic functions
<br />would be restored to pre-construction conditions.
<br />When possible, local contractors would be hired for earthwork and general
<br />reclamation and demolition work, see reclamation schedule, Figure N2. The
<br />overall reclamation of the Orchard Valley Mine would include the conveyor
<br />belt reclamation. It is anticipated that fewer than 30 workers would came
<br />from outside the area.
<br />Economic Feasibili
<br />Analysis in Appendix "C" shows that the truck dump and short conveyor belt
<br />alternative is not economically feasible at this time. An estimated capital
<br />investment of $3,691,000 would be required, This alternative is less econo-
<br />mically favorable than the overland conveyor. Both conveyor systems are
<br />less favorable than the current transportation alternative of trucking,
<br />Prudent business would dictate construction of the overland conveyor, not
<br />the truck dump and short conveyor, if sufficient markets were obtained,
