EXHIBIT D Mining Plan The primary purpose for the products from this mine will be to provide Moffat County with the materials necessary to construct and maintain the County Road System in the vicinity of the Limestone Pit No. 10. The products will be mined, sized, sorted, crushed, mixed, stockpiled and removed with standard operational gravel and limestone mining equipment. (For an inventory of Moffat County's equipment see Exhibit C -2 (page 2). The typical profile of the soils can run from zero to a few inches of topsoil and loam, and some areas may be burdened with 20 feet of sand and sandstone above the limestone. Moffat County will strip the topsoil, where it exists, and stockpile it separately in an area protected from stormwater flooding, then seed it with Moffat County's seed mix formula (see Exhibit E -2). In addition, we will strip the sand and other overburden, then stockpile and seed them in an area protected from stormwater damage. Construction Materials exist in some form throughout the 86.40 acre State lease (see Exhibit A). For example, there are mineable areas of Limestone, Sand, Gravel and Clay on top of the ridge as shown in Exhibit C -2 (page 1) identified as "Blasting Zone # 1 and Blasting Zone #2. The limestone in both Blasting Zones appears to be of the Morgan Formation, which usually contains limestone, sandstone, and shale. A review of Exhibit C -4 (pages 1 thru 4) will show the limestone outcrops on the aerial photo, and in the attached photographs. Moffat County will mine some of the limestone layers on the surface with a Dozer, Trackhoe, and a 980 Cat. Loader. And we will mine sand, gravel and clay as needed. Heavy limestone layers will be drilled and blasted by a licensed and experienced blaster under contract to comply with all of the necessary MSHA and /or OSM surface mining regulations. Moffat County's Contractor will design a blasting plan that would address the slope of 3' to 1' (Horiz. To Vert.), or flatter on the final slope. In addition the Blaster will: (a) Identify all Man -made structures within % mile of the blasting area (type of structure, age of structure, type of material the structure is constructed of, etc). (b) Identify all potentially unstable geologic conditions within 200 feet of any structure (ie. highly fractured cliffs, etc.). (c) Commit to complying with the maximum allowed peak particle velocity and maximum allowed airblast (air overpressure), which are 1.0 in. /sec.ppv and 129 dBL respectively. (d) Commit to keeping records of each and every blast event. (Record keeping requirements are attached). Copies of the record keeping requirements must be provided to the Division of Reclamation, Mining and Safety (See Exhibit D -1).
