Ms. Anne C. Baldrige December 21, 1984 Page 2 C Craig Jennings, Engineering Manager at the Seneca II mine, contacted the • Colorado Yampa and Trapper mines through R. N. Robinson & Sons, Inc., a local dirt contractor. Once again, even though a brush blade was found, equipment incompatibility prevented the use of the blades. The final contacts were made by Clarence Jaquess, Manager of Heavy Equipment in Peabody's Denver office. Clarence contacted Power Equipment and Wagner Equipment here in Denver. These companies service Peabody's Fiat-Allis and Caterpillar equipment and were the most logical contact fora brush blade attachment for our equipment at Seneca II. Once again we were unable to find a brush blade for leasing or renting through these contacts. Because of our failure to find a brush blade for brush removal trials at the Seneca II mine, Peabody proposes to improve the execution of our present brushing techniques as part of the quality control program for topsoil removal. The improved execution will include an information and training program for the dozer operators and mine reclamation personnel. This will accomplish several goals, including: (1) A review of present techniques and execution as well as problems that are presently encountered in brush removal; (2) improved understanding by dozer operators and mine reclamation personnel of the importance of maximized topsoil salvage, upper lift recovery and handling, and how these result in the overall and long term reclamation success and the meeting of our revegetation success criteria; and (3) suggestions and changes that can be implemented to meet these goals and improve the quality control program for topsoil recovery. • These activities will be monitored over the next year and, as part of the , revegetation monitoring plan to be implemented during the 1985 field season, soil sampling associated with vegetation sample points will be carried out to evaluate the overall topsoil replacement program to date. In addition, an annual topsoil sampling program is carried out on graded spoil and re- placed topsoil for reclaimed areas during a given year. Together, these ongoing programs along with periodic observations of equipment operators, will provide a good base for evaluating the quality control program. Thank you for your consideration of this alternative to the stipulation attached to Technical Revision #6, Wadge Area Topsoil Technical Revision. If you require any additional information or clarification please do not hesitate to contact me, Gary Wendt (Soil Scientist) or Tom Wainwright here in Peabody's Denver office.
