A. Refer to response G. 6. <br /> 8. Q. On the shrub plantings, we need a more <br /> definitive statement as to what you would plant <br /> now if you had to reclaim it now. Also , we need <br /> an indication of the pattern of planting that <br /> would be used . <br /> A. In our current reclamation program we utilize <br /> various shrubs including raspberry, wild rose , <br /> cinquefoil , willow, sagebrush , and snowberry. <br /> The performance of some of these shrubs is still <br /> being evaluated . If we had to reclaim finally <br /> today we would want to use raspberry, wild rose , <br /> cinquefoil and willow. Our pattern of planting <br /> has been a clumped distribution over large <br /> areas. Then, within the clumps , we have planted <br /> with both regular and clumped distributions . <br /> The clumps are spotted randomly on homogeneous <br /> sites. On heterogeneous sites they are spotted <br /> according to aspect, slope , position on slope <br /> and growth material . <br /> 9 . Q. What is your best estimate of the duration of <br /> the fertilizer maintenance program? <br /> A. Our best estimate of the duration of the <br /> fertilizer maintenance program is as follows : <br /> Sites with " inplace" topsoil 0-2 years <br /> Sites with subsoils 2-5 years <br /> Very steep sites 3-7 years <br /> Waste rock with topsoil 1-3 years <br /> Waste rock with sewage <br /> sludge and wood chips 5-8 years <br /> Reapplication should not be required during each <br /> year of the program. <br /> 10. Q. Since 1977 , what studies have been done on <br /> sewage sludge? Has a source for properly- <br /> digested or stable sewage sludge been found yet? <br /> Exactly what does Climax plan to do at this time <br /> as far as the use of sewage sludge is concerned? <br /> A. Climax will rely heavily on the Urad Mine <br /> reclamation experience with sewage sludge , <br /> -16- <br />
