This year we have hosted a public tour of the <br /> site, which was well received. 'We remain active with local <br /> interest groups by periodically attending their meetings in order <br /> to provide information regarding the reclamation process. We will <br /> continue to entertain a high level of public input throughout the <br /> reclamation process. <br /> Reclamation Activities <br /> 1995 <br /> The Division reclaimed approximately 42 acres last year. This <br /> acreage was divided between three projects which were completed by <br /> independent contractors. <br /> Waste Piles: This project accomplished final grading, stream and <br /> diversion channel construction, topsoil application and <br /> revegetation. Reclamation of the two waste piles accounted for <br /> about 23 acres of revegetation work. <br /> Mines 3 and 4: Structural demolition, outslope and highwall <br /> reduction, sediment containment and revegetation work was <br /> accomplished. About 10 acres were reclaimed at each location. <br /> During completion of this project it began to become apparent that <br /> conventional hydro seed and hydro mulch application at high <br /> altitude sites may not yield the best results. This is primarily <br /> due to both steepness of slopes and intensity of afternoon rain <br /> showers and snow melt runoff. <br /> Miscellaneous: Steep slope revegetation experiments were <br /> initiated. A steep slope was divided into four test plots. In one <br /> section, hydro seed and hydro mulch was applied with fertilizer as <br /> at Mine 3. In another section, logs were anchored to the slope, <br /> and the area behind the log filled by shoveling dirt from <br />
