R~C~Bi/~® July 15, 1983 JAPJ 1 `~ '96.1 fiINED LAND kECLAMATION DIVISION Colo. D~cyf~~r~~sources RALSTON QUARRY 1983 ANNUAL RECLAMATION REPORT The phased reclamation schedule under which we are operating is proceeding as per original plan and approved by Jefferson County on April 16, 1975. Physical Appearance Our present grading and removal operation is being conducted so that the floor will be level with the surrounding area. No hole or depression of any nature will be left upon completion of mining. There will be a slight crown left in the middle of the property running north and south so as not to interfere with the natural drainage pattern. An excavated area is on the east side of the quarry floor to hold dust suppression water and prevent any floor runoff. Topsoil Topsoil and overburden material are presently stockpiled as depicted on the map and are being used in the restoration program. We continue to grade and restore the surface area of the initial removal area. The seed mixture being used is in accordance with the previously determined recommendation of THK Associates and Dave Boyle, County Extension Agent at the time. The results we feel are very successful as well as similar to the original test plant areas. This past May, we placed more topsoil and reseeded all the level areas. Final Benches The final benches and the restoration thereof are, of course, some years away yet. Fugitive Dust We feel we are presently using sufficient water, along with proper spray bar equipment in efforts to comply with dust emission standards. Roads All back slopes have been seeded and the establishment appears to be successful. The roadtop surfaces have been watered and oiled to prevent dust. East Berm This berm has been enlarged and continues to show evidences of natural vegetation which has established itself. The seed is progressing satisfactorily as well. This berm not only serves aesthetic functions, but prevents potential surface water from draining in an uncontrolled manner. We shall, in the future, as we have in the past, continue to update our per- formance concerning land stabilization and reclamation. We feel the approved reclamation plan is progressing satisfactorily and according to the timetable approved in the original application.
