~~. United States Department of the Interior BUREAU OF LAND MANAGEMENT GRAND JUNCTION DISTRICT 764 HORIZON DRIVE GRAND JUNCTION, COLORADO 81501 February 5; 1981 Dennis Conn Environmental Specialist GEX Colorado Inc. ` P.O. Box W Palisade, Colorado 81526 Dear Dennis, w rteecr rseeen i+o: 3530 7-130 The attached proposal represents my initial response for establishing a research project at the Roadside mine for evaluating coal refuse reclama- tion in our semi-arid Grand Valley. The meetings, site visits and litera- ture exchanges have been very helpful for determining mutual objectives and site determinents for the GEX reclamation responsibilities and our research needs. I will hope that our proposal can compliment your reclamation plan, and that GEX obtains the necessary permits for reclamation implementation. At this time, it is suggested that a variance for an "Experimental Prac- tices" permit (Section 2.Ob.2 Colorado Mined Land Reclamation Board Regulations) be requested for the site in question. Even though we are not recommending any innovative reclamation solutions, we are trying to eval- • uate previous solutions (seed, mulch and applications) to select the most effective for our unique climate and soil limitations. Under these condi- tions, I recommend that you emphasize the research aspect of Section 2.06.2, Paragraph 5(e)(i) and a substantial data collection process for 1) statistical analysis, 2) water monitoring, 3j performance, 4) soil stabil- ity, and 5) precipitation rates. The rate of cover establishment would be monitored by quadrat transects anc clipped plots within the three replications of each treatment. Climate and water monitoring would support the research application and the validity of the experiments; even though the BLM could advise regarding these facili- ties, their installation and utilization would remain a GEX responsibility. It is expected that traditional analysis procedures would be applied to monitoring the revegetation process. Incremental documentation procedures for the research plats and monitoring stations would be established as a cooperative effort between the BLM, GEX and any designated consultants. Report documentation would also be a key factor in BLM participation so that a summary analysis could be made available to interested parties. This final assessment would represent the termination of the BLM-GEX co-operative association;~future funding would dictate the date of this termination but five years is considered minimum f_or obtaining valid results, .and I would hope for at least five years involvemeht with the research pldt.
