Candace Thompson Colorado Mined Land Reclamation Division 423 Centennial Bldg. 1313 Sherman Street Denver, Colorado 80203 Re: Rill and Gully Plan, Coal Basin Mines: File No . C-017-81 Dear Candace: Following is our revised plan per Jeff Deckler's comments : The Coal Basin mines have operated since 1956 . The mine pads were constructed at 10, 000 feet , plus or minus, by down-sloping the material adjacent to the Coal seams . Various other mate- rial was down-sloped from 1956 to 1977, including trommel screen rock and road. grading material . These outslopes are at the angle of repose, or approximately 1 to 1 -slope,. and have many rills and gullies. We believe, first , that these slopes are grandfathered and so are exempt from a rill and gully plan; and second, when compared with the adjacent natural hill slopes they show approximately the same erosion pattern. Our present plan is to monitor our postmining stabilization test section (at No. 4 Mine) and evaluate possible .postmining stabilization/ reclamation methods. This is a ten-year project along with our outslope vegetation test plot program and includes the entire mine road system. See Vol . 7, Chapter V, Page 21. 1 and old stipulations 22 and 26 plus new stipulations 6 and 8. The rills and gullies associated with our old coal refuse pile and our present coal refuse pile and tunnel rock pile will be addressed in the following manner : Old Refuse Pile Portions of this pile date back to 1956 and are thus grand- fathered . Some of these old portions have been reclaimed while others have not . It will be our policy to continue reclamation on these old areas as time, money and technology permit .
