Mike Long - 2 - October 7, 1986 The Division did not respond within thirty (30) days as there was a question whether the Division could release when the permit was under Board-ordered suspension. It was determined the Division would release, remaining work was valued at less than the 40 percent of the total bond amount to be retained, and the process was completed on September 24, 1986. S ep cific The following items identify specific permitting activities which require attention at the present time. Also listed are areas at the mine site which have been more active recently. NOV C-86-068. Sediment Pond 15-P20 was observed on September 30, 1986 to e r e above the clean out level. The recently regraded Pit 5, Cut 10, which is upslope of the pond, was the source of sediment during recent rains. Abatement by cleaning out the pond should be performed before December 1, 1986. NOV C-86-069. This violation was written because an extensive gully a~~reater than 24 inches deep in the Pit 2, Cut 4/5 area. A minor revision was approved March 29, 1985, to allow a permanent gully in Swale areas. During the March 1986 bond release inspection this specific area was noted to require stabilization. Instead, during August regrading work, the gully was removed by grading it over. As anticipated, the gully reformed and considerably lengthened itself. Abatement to repair the gully should be performed before December 1, 1986. _ _ _ Rills and Gullies. As all of the hillslope areas have been reclaimed, continue o nervation of gully formation should be a focus of further inspections. From experience, the following areas are identified as known locations to inspect: Pit 1, area 100 feet northwest of drainage crossing the access road; Pit 2, Cut 1 area 0.5 miles on road from shop - above road at water bar; Pit 2, Cut 4/5 as mentioned above; Pit 2, Cut 6/7 area, two side-by-side gullies exist, should be formed into one permanent gully; Pit 2, Cut 12 at outlet of ditch 22-D6, recent regarding of channel ditch outlet into one gully instead of three; Pit 2, cut 13/14, general rilling along entire hillslope; Pit4, Cut 18/19 where road bends sharply, two gullies at side should be rock stabilized. These gullies are identified on the map in the inspection packet. Reve etation. Areas in which vegetative growth is sparse and oversee ing may be necessary have been identified on the map in the inspection packet. Sufficient bond has been retained for complete reseeding of these areas if necessary. Some areas were regraded this past August and supposedly seeded and mulched. These areas are described in the July 1986 inspection report. Topsoil was removed from a stockpile in Cut 8 of Pit 5 and redistributed to Cut 10. The Cut 10 area, because of its relatively steep slope, is the area of most concern. The operator plans to observe seeding success this next spring and reseed the regraded areas if necessary.
