The maintenance of the pipeline would require inspection by liyht-truck vehicles on an as-need basis. The lack of mechanical parts requires less maintenance than a conveyor system. Appropriate preventive maintenance would be completed on the capsule train so as to preclude plugging of the pipeline. At the current production rate, ten truck drivers are employed for trans- porting of coal at the Orchard Valley Mine, With increased production, additional truck drivers would be employed, Initially, with construction of the pipeline, no change woulq be made to the number of truck driver employ- ees, Upon operation of the pipeline, all truck drivers would be laid off, CWI expects additional employees would be needed to be hired to operate and maintain the conveyor, Because of the unknown technology of the system, the number of additional employees cannot be estimated at this time, Reclamation After the Orchard Valley Mine had ceased operations, the pipeline, loading, and unloading facilities would be dismantled and salvaged for possible re-sale, The steel support structures, foundations, and associated building materials would be removed and the sites backfilled to approximate original contour, Topsoil and subsoil would be re-excavated from the pipeline route and the pipeline removed. Water bars would be constructed to control drainage and the pipeline route revegetated, On the other hand, dependent upon the cir- cumstances at the time of final reclamation, CWI along with the Regulatory Authority, might elect to leave the buried pipeline in place so as not to re-disturb the entire route again, • The pipeline route and unloadiny facilities located on the alluvial, agri- cultural lands would be regraded, topsoil redistributed, and irrigation pat- terns restored. Pasture, orchard, or other appropriate vegetation would be replanted on these sites. The specific procedure for reclamation of this area would be the same as for the existiny storage and loadout facilities, refer to Appendix "M" for the procedure. All essential hydrologic functions would be restored to pre-construction conditions. When possible, local contractors would be hired for earthwork and general reclamation and demolition work, see reclamation schedule, Figure M2. The overall reclamation of the Orchard Valley Mine would include the pipeline route reclamation. It is anticipated that fewer than 30 workers would come from outside the area. Economic Feasibility As stated previously, the pneumatic capsule pipeline system is an innova- tive, unproven made of coal transportation, TUBEXPRESS Systems, Inc, is considering the Orchard Valley Mine as the first commercial prototype unit site, At the present time, CWI cannot assess the economic feasibility of con- structing the pneumatic capsule pipeline system. Financial arranyements have been discussed with TUBEXPRESS Systems, Inc „ but to date, development ' and construction cost uncertainties prevent the owner from committing neces- sary financial data to CWI. 33
