This solution may be applicable in a few limited <br />areas throughout the length of the haul road. <br />3) Timber, wire basket (gabbeion), metal or precast concrete cribbing, <br />~. could be installed in particularly troublesome areas. However, its <br />.. cost will be high. <br />4) In a few limited areas of lower slope, it may be possible to reduce <br />the cut face angle. This should be done sparingly and only after <br />a careful examination of the proposed cut area by an appropriately <br />experienced professional. <br />The unfortunate fact is that Grassy Creek Coal has a severe operational <br />problem. The realities of business economics will dictate that the <br />company correct those failure areas which are affecting their ability <br />to haul coal, and therefore generate income. They will, however, <br />probably be forced to ignore those areas which only constitute aesthetic <br />nuisances. This is probably acceptable if the haul road is not a public <br />right-of-way. 2 believe it would be prudent, however, to require the <br />company to post warning signs reading, "landslide area - proceed with <br />caution" at appropriate locations in order to advise the public of the <br />existing hazard. . <br />Jim Pendleton <br />/k <br /> <br />
