1993 ANNUAL RECLAMATION REPORT <br />NAME: The Pittsburg & Midway Coal Mining Co. <br />Edna Mine <br />P.O. Box 176 <br />Oak Creek, CO 80467 <br />PERMIT #: C-80-001 <br />LOCATION & NUMBER OF ACRES DISTURBED: <br />Disturbance during 1993 was from topsoil stripping, mining <br />activity and West Ridge hydrologic plan work. Approximately 77.5 <br />acres of topsoil was stripped in the Moffat Area. This area is <br />shown in Exhibits 1 and 2 in the attachments. Most topsoil <br />stripped was live handled to the graded area behind active mining <br />activity except for an approximately 175 ft, wide strip that was <br />windrowed ahead of mining activity until ground conditions allowed <br />for its haulage. Mining disturbance areas were limited to the <br />Moffat Area. This area covered approximately 60.9 acres and is <br />shown on Exhibits 1 & 2 labeled as "Coal Removal Area". West <br />Ridge Hydrologic plan work involved construction of the check dams <br />12 through 21 the drainage area between Center Ridge and West <br />Ridge and the lower sections of terraces draining to these <br />structures. The area disturbed for this activity is roughly <br />outlined in Exhibits 1 and 3. These activities were detailed in a <br />report sent to the MLRD in late 1993. <br />LOCATION & NUMBER OF ACRES BACKFILLED AND GRADED: <br />Backfilling and grading activities encompassed a total of 113.2 <br />acres. Of this total 71.3 acres was final grading in the Moffat <br />Area, and is outlined in Exhibits 1 and 2. The remaining 41.9 <br />acres was final grading activity in the West Ridge Area as shown <br />on Exhibit 3. <br />LOCATION & NUMBER OF ACRES TOPSOILED: <br />Topsoil stripped was from the Moffat area covering 77.5 acres most <br />being live handled and the remainder windrowed ahead of mining <br />activity. Topsoil removal areas are shown on Exhibits 1 and 2. A <br />total of 9159 loads of topsoil were removed and replaced during <br />1992. Using a Cat 637 scraper struck capacity of 30 cubic yards <br />this equates to approximately 274,770 cubic yards of topsoil. <br />Assuming that a strip 175 feet wide by 2800 feet long was <br />windrowed and not hauled this would mean that the average stripped <br />depth on a swelled basis was 2.6 feet. Normal mine policy of <br />removing all available topsoil was followed. <br />Topsoil replaced during 1992 was on reclaimed locations in the <br />Moffat Area and covered 63.6 acres. These areas are shown on <br />Exhibits 1 and 2. The eastern most area of topsoil replacement <br />
