Handbook of Western Reclamation TechniquesThe Handbook of Western Reclamation Techniques is the culmination of cooperative effort of the mining industry, industry professionals, the academic community, and regulatory agencies. It is designed to document field-proven reclamation methods. The field techniques described in the handbook demonstrate the variety of different methodologies used to accomplish similar reclamation tasks. Many of these techniques were developed from scientific studies and have evolved over time. Although mining has occurred for over a century, concerted reclamation efforts for coal mines began in response to laws such as the Wyoming Environmental Quality Act (WEQA) of 1973, and the Surface Mining Control and Reclamation Act (SMCRA) of 1977. Reclamation that has been successful allows surface coal-mine operators to redeem bonds that they posted prior to the making their initial disturbances. These reclamation bonds are required by SMCRA and WEQA. The roots of reclamation science lie in the conservation practices developed during the Dust Bowl and Depression years of the 1930's. Many of the practices developed, and much of the work done during that time, were funded by Federal and State governments. For this reason, many of the names associated with early reclamation of mined lands McKell; Bjugstad; Power, Sandoval, and Ries; Aldon; Plummer; Richardson and Farmer; and Hodder are also names from the Soil Conservation Service, the Agricultural Research Stations, and land-grant universities. Early mine reclamation was so closely associated with agriculture that reclamation and revegetation were considered virtually synonymous. While some agricultural emphasis continues today, the technology has expanded greatly to embrace hydrology, wildlife, and compliance. Reclamation science has responded to legal requirements, reconstruction of endangered habitats, revitalization of damaged environmental systems, and establishment of wetlands. Reclamation methods are used to minimize the impact of human development in housing subdivisions, on ski slopes, and in highway reconstruction. Early reclamation investigations in the arid and semi-arid Western United States were based on research trials for replacing soils and reestablishing vegetation. Cook et al. (1974), Power et al. (1976), the U.S. Forest Service Surface Environment and Mining Program (1979), and DePuit and Coenenberg (1981) are good examples of earlier efforts that continue today in work by Schumann et al. (1993). Plant-materials centers and agricultural research stations continue to provide tools for reclamation efforts (e.g., Ries et al. [1976], Aldon [1981], Bjugstad [1984], and Majerus et al. [1985]). Researchers such as Shroeder (1985), Toy (1983), and Toy and Parsons (1987) produced research on geomorphic processes such as erosion, infiltration, and sediment yield, while Beauchamp (1973), Dollhopf (1978), Berg (1983), and Halvorson and Doll (1985) investigated spoil and soil in the reclaimed environment. A great deal of applied research has been conducted by mining companies interested in seeking new solutions to reclamation problems. Much of this work is reported in the annual reports required by State agencies for each active mine. Postovit (1981), Hingtgen and Clark (1984a and 1984b), Yoakum (1984), Clark and Medcraft (1986), and Medcraft and Clark (1986) studied the effects of mining on wildlife populations. Olendorf et al. (1981) and Nelson et al. (1978) described techniques for wildlife-habitat restoration. Methods and classification for reconstruction of stream channels are being developed by Wesche et al. (1993) and Rathburn et al. (1993). There are many works that suggest technologies of various kinds, report on field trials, and recommend plant species for use in reclamation. However, 20 years after the earliest efforts, a considerable body of practical knowledge has been developed among the specialists charged with the duty of complying with State and Federal statutes and regulations governing reclamation of mined lands. For the most part, this knowledge has never been formalized and made generally accessible until its presentation in this handbook. The original Handbook of Western Reclamation Techniques was designed in a binder format with the capability of adding or replacing sections as new techniques are developed. Plans and diagrams can be easily removed to make working copies of a subsection. This handbook has been written and assembled by the volunteer labor of interested authors and a smaller volunteer editorial committee. Many of these people gained their experience in the surface coal mines of Wyoming. Abandoned Coal Mined-Land Research Program funds were utilized for support services such as administration, assembly, drafting, literature review, and word processing. The handbook was printed by the Office of Surface Mining. It is the intent of the authors to present in this handbook, in an accessible format, economical and successful reclamation techniques that have survived the test of practical application. Many of the techniques are a cumulation of scientific studies and practical experience. Since some of these methodologies may not have been previously documented, the authors feel compiling this handbook is an important contribution to reclamation. It is the hope of the authors that the distribution of these techniques will positively affect not only the reclamation of surface coal-mined lands, but will also be of potential service in many reclamation fields.
