(Continued page 2) Exhibit D Amendment No. 002 Mining Plan 2. Moffat County will regrade all reclaimed slopes to gradients no steeper than 4H:1 V. 3. Moffat County will not be released from reclamation responsibility until after a successful crop harvest. See Attached: 1. Conditional Revision Approval, Moffat County, Lyons Pit No. 2, Permit No.M-80-248, Revision No. CN-01 (March 28,1991); 2. Exhibit D -1997 Mining Plan; 3. Exhibit E -1997 Reclamation Plan Changes and/or additions to the attached Mining Plans: Seed Mir Formula: Moffat County, the BLM and the Division of Reclamation, Mining and Safety, have replaced all of our individual Seed Mix Formulas with the formula on Exhibit E-2. We will limit our use of this formula to Overburden and Topsoil storage piles, and to stormwater erosion prevention because the post-mining use of the affected land will return to the pre-mining use of irrigated and dry crop agriculture to be reclaimed under the 1997 Reclamation Plan. Mining Zone: Moffat County's primary mining activity will be to expand the Pit Area of the Lyons Amendment No. 1 to the south and to the east as shown on Exhibit C-4 (Mining Plan Map). Overburden and topsoil will be stored in the designated areas, and the gravel stockpiles will be stored in the bottom of the pit similar to the way they are now shown in Amendment No. 001 on Exhibit C-1. Based on our experience in the Lyons Pit No. 2, and in Amendment No. 001, we believe there will be 16 feet of overburden, 13, feet of gravel, and 3 feet of clay in Amendment No. 002. The bedrock is Shale. Signs and Markers: The boundary corners for Amendment 002 are already marked by signs in the existing fenceline, and/or mounted on steel posts marking the project boundaries. Moffat County will continue to position signs on the topsoil, overburden, and stockpiles. Explosives: Moffat County does not use explosives in any of our gravel mines.
