Tapics  Sage Creek Coal Ltd.  rd  Proceedings of the 3 Annual British Columbia Mine Reclamation Symposium in Vernon, BC, 1979. The Technical and Research Committee on Reclamation  5  RECLAMATION OF EXPLORATION DISTURBANCES AT SAGE CREEK  INTRODUCTION Sage Creek Coal Limited was incorporated in 1970 under the Companies' Act of British Columbia. It is managed and 60% owned by Rio Algom Limited in Toronto and 40% owned by Pan Ocean Oil Limited in Calgary.  The Sage Creek Property is located in the southeast corner of British Columbia, about 10 miles west of the Alberta border and about 8 miles north of the United States boundary. Exploration work has been conducted on the property from 1970 through 1977. Approximately 200 acres of land were disturbed through the establishment of 30 miles of roads, 4,400 feet of trenches, 14 adits and drill sites for 159 holes.  These disturbances were concentrated on two large hills which are  separated by Cabin Creek.  Throughout this paper these hills will be  referred to as North Hill and South Hill.  Cabin Creek is a tributary of  the Flathead River.  Due in part to high expectations for obtaining a sales contract and, in part, to a sequence of field programs which were conducted over the same general area, seeding and fertilizing were not carried out from 1970 through 1976.  Rio Algom felt that there was no point in reclaiming land  one year that would be redisturbed the following summer.  However, erosion  control was done through the use of ditches, berms on roadways and water bars; and trenches were recontoured soon after they were excavated.  Reclamation of all disturbances was undertaken during the summer of 1977 and 1978.  Most of these disturbances occurred between the 4,300 and 5,500  foot elevations.  rd  Proceedings of the 3 Annual British Columbia Mine Reclamation Symposium in Vernon, BC, 1979. The Technical and Research Committee on Reclamation  6  RECLAMATION PROGRAMS Disturbances were divided into three main areas: the north face of South Hill, the south face of North Hill and general access roads and drill sites.  Reclamation was divided into two programs:  A 1977 program which  concentrated on the first two areas; and a 1978 program which involved general access roads, drill sites and maintenance work on the previous year's reclamation.  The North Face of South Hill I will concentrate on the north face of South Hill since this area posed the biggest problem.  Surface erosion had occurred in the vici-  nity of adits. Since this area was saturated with water, it was impossible to use tracked equipment without site preparation.  Preliminary work involved  the use of a D6C bulldozer to upgrade roads.  This upgrading included  cleaning out ditches and construction of water bars and diversion berms.  A layer of rock rip rap was spread in the high moisture content areas in the vicinity of adits.  To accomplish this, rock was dozed out of  nearby roadway rock cuts.  This material was also pushed into washouts  to stabilize slopes and to form french drains. Large trees that were undermined by erosion were cut up and removed from the site.  To avoid unnecessary damage and to aid in stabiliza-  tion, minor forest debris was left on the slopes. debris acts as a heavy vegetative mulch.  In addition, the  rd  Proceedings of the 3 Annual British Columbia Mine Reclamation Symposium in Vernon, BC, 1979. The Technical and Research Committee on Reclamation  7  Final control measures included the construction of a cut-off ditch along the toe of the final slope. Water and fines collected by this ditch are discharged into a small settling pond, and the excess water from this pond is discharged into dense bush for further filtering. After one year's use of this system a sediment fan was formed which contained coal fines.  A second settling pond was constructed at the  base of the hill before final discharge into Cabin Creek. Three separate seeding techniques were applied to the north face of South Hill.  Steep slopes were hydroseeded, mulched and fertilized  using 50 pounds of grass/legume mix, 875 pounds of wood fibre mulch and 200 pounds of 16-20-0 fertilizer per acre.  Roads were broadcast seeded  with 30 pounds of grass/legume mix and 200 pounds of 16-20-0 fertilizer per acre.  Steep inaccessible areas were hand seeded with 30 pounds of  grass/legume mix per acre. The seed mix by weight used in all cases was: Creeping Red Fescue  -  25%  Kentucky Bluegrass  -  20%  Climax Timothy  -  10%  Perennial Ryegrass  -  10%  Vernal Alfalfa  -  15%  Redtop Fescue  -  5%  Chinook Orchardgrass  -  15%  After one year the seed germination results obtained were very good. The slope stabilization program proved to be quite effective with only minor slumps occurring in some of the washouts and steep road banks. Most of the downhill movement of water was restricted to the ditches and settling ponds.  rd  Proceedings of the 3 Annual British Columbia Mine Reclamation Symposium in Vernon, BC, 1979. The Technical and Research Committee on Reclamation  8  The South Face of North Hill This area is very dry and exposed, with little or no surface water present.  Reclamation was designed to restore the aesthetic values of the  site and to speed up the restoration of the area to its principal land use.  It was felt that establishment of a grass/legume stand on the  area would achieve these objectives.  Some minor road work and contouring  was done using a caterpillar tractor, primarily to provide access for the seeding equipment. .Seeding was confined to hydroseeding and mulching. Specifications were similar to the South Hill, with the following seed mixture by weight being used: Magna Bromegrass  -  25%  Sweet Clover  -  10%  Crested Wheatgrass  -  20%  Creeping Red Fescue  -  20%  Sainfoin  -  15%  Kentucky Bluegrass  -  10%  In addition, 45 pounds per acre of Fall Rye Grain were sown as a cover crop.  The rye germinated rapidly and helped to reduce soil tem  peratures and hold soil and moisture.  Otherwise, seed germination on  this particularly dry site was not as successful as it was on South Hill. Access Roads, Drill Sites and Maintenance of 1977 Program Work All roads were ditched, water bars were constructed as required, and the areas were seeded, fertilized and harrowed followed by application of the same seed poundage per acre and the same type of fertilizer as was used previously.  rd  Proceedings of the 3 Annual British Columbia Mine Reclamation Symposium in Vernon, BC, 1979. The Technical and Research Committee on Reclamation  9  Areas from the 1977 program that experienced incomplete stands of grass were either reseeded and fertilized or were hand seeded. The seed mix used in dry areas was the same as that applied to the south face of North Hill, whereas the seed mix used in wet areas was adjusted slightly from that applied to the north face of South Hill. Since the Alfalfa did not germinate well, it was replaced by Alsike and Double Cut Red Clover in the blend.  These were chosen due to our  reclamation contractor's success with them at other sites.  COSTS In 1979 dollars, the 1977 program expenditure was $36,000 for 55 acres, and included substantial dozer time.  On this same dollar basis, the 1978  program cost $38,000 for 145 acres.  Based on these past programs, approxi-  mate 1979 unit costs would be $260 per acre for tractor seeding, fertilizer and harrowing; $165 per acre for hand seeding; and, $540 per acre for hydroseeding, mulching and fertilizing.  The average cost per acre to-date  for the program is approximately $423.  However, some maintenance work will  be necessary which, it is anticipated, may reach $500 per acre to completely reclaim the site.
