I ' MID-CONTINENT RESOURCES, INC 201 Centennial St.,Suite 406 Glenwood Springs, Colorado 81601 (303)945-4958 z; May 20, 1985 Ms. Candace Thompson Mined Land Reclamation Division 423 Centennial Building 1313 Sherman Street Denver, CO 80203 RE: Rill and Gully Plan (rule 4. 14. 6) Coal Basin Permit CO-017-081 Dear Candace: Enclosed is our proposed Rill and Gully plan for the Coal Basin mines. The Coal Basin mines have been in operation since 1956 . The mine pads were constructed at 10, 0001+ by down-sloping the material adjacent to the coal seams. Various other material 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 #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 grandfathered. 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.
