Joseph Sullivan , Chairman <br /> March 7, 1980 <br /> Page Two <br /> A technical revision of the permit was requested in <br /> April 1979 relative to Area 10, Ryan' s Pit and Storage . The <br /> revision will allow continued aggregate production from this <br /> area according to projected needs. <br /> Grass seeding of the topsoil stockpile (Area 21 ) and <br /> associated roads accomplished in the Fall of 1978 did well in <br /> 1979 and is providing a good vegetative cover . Several <br /> hundred tree and shrub seedlings were planted on the topsoil <br /> stockpile in 1970 . <br /> Continued tailing deposition now affects about 390 <br /> acres. That figure and the other disturbances inside the <br /> tailing basin (bypass canal , roads, pipelines and topsoil <br /> removal) puts us within the 425 acres of anticipated affected <br /> land designated for the tailing in the timetable for 1979 . <br /> Other 1979 activities included : <br /> 1 . At the mine site an addition was made to the west end of <br /> the compressor building . A third exhaust ventilation <br /> fan and elbow were constructed at number one shaft. . A <br /> fuel storage island with a capacity of 157, 000 gallons <br /> was constructed . <br /> 2 . In the mill yard construction on a fourth primary ball <br /> mill and associated facilities was begun. Temporary <br /> construction administration office buildings were <br /> implaced as a part of the mill expansion project. <br /> Additional equipment maintenance buildings were <br /> constructed which will be taken over by the maintenance <br /> department upon completion of the construction project . <br /> Because the acreage of affected land is changing daily <br /> ( tailing deposition) , our original application suggested that <br /> we would update the surety yearly at annual report time. <br /> When the Board acted on the application, they indicated that <br /> a biannual surety update would be adequate. We have <br /> recalculated the reclamation costs in accordance with that <br /> directive and upon your approval , will provide a surety for <br /> the new amount. <br /> The recalculated reclamation costs ar $2 , 596 , 000 > <br /> covering 1232 acres of affected land (within It <br /> boundary of 6628 . 6 acres) and covers the period 1980 through <br /> 1981 at which time the annual report will again recompute and <br /> update the surety. A copy of the recomputation is enclosed . <br />
