Cross-Section along centerline of Toner Ranch Pit (access road) <br /> k. At some point, relocate the storage/truck-loading area and work area (plant site)to the floor of <br /> the pit, to allow mining of the area where these were initially located and to reduce haul <br /> distances. Locate the processing plant(s) only intermittently on the Permit area, to produce <br /> finished products, with the plant(s) likely in a different location within the permit area each <br /> time. Regrade access road as necessary at that time. <br /> I. As mining is completed and final grade is achieved on the southwestern edge of the permit area, <br /> place soil stripped from the next areas to be mined on the slopes and floor of the pit and seed <br /> (see Exhibit D). <br /> m. After mining the southern and central portions of the permit area, strip and mine the northern <br /> portion of the permit area. (See map, Exhibit E). <br /> 4. Scheduling and production (6.3.3.(a)): Commence mining in the Spring of 2021 (anticipated), once <br /> snow is gone and ground is capable of supporting equipment. <br /> a. End mining (and sales of products from stockpiles on the permit area) in about 10 years, <br /> completed by the Fall of 2031, assuming demand will be sufficient. Length may range from 4-9 <br /> years. <br /> b. STATEMENT OF INTERMITTENT OPERATION: The operator may, due to demand, weather and <br /> elevation, be unable to use the affected lands for at least one hundred eighty days per year, but <br /> anticipate operating (excavation, processing, shipping) within one year of any temporary <br /> cessation of operations, and materials will remain stockpiled on the permit area. <br /> c. Up to 217,800 cubic yards (326,700 tons) of reserves, approximately 36,300 tons/acre, or <br /> average shipping of 33,000 tons/year if 10 years, or 47,000 tons/year if 7 years' duration. <br /> (Generally, about 50,000 tons will be processed each time the portable plant is on-site, unless <br /> demand is great enough to require more.)This is based on known information/depth estimates. <br /> d. The landowner is anticipated to request that small quantities of processed construction <br /> materials may be left on the permit area at the end of mining, for their own use on the property <br /> and contiguous property. This is not expected to require more than 0.25 acres and will be <br /> approved by landowner when submitting for final reclamation release. <br /> 5. Soil/Plant growth medium (6.3.3.(b)):As stated in Exhibit B,4-5 inches of soil (A horizon) will be <br /> stripped and stockpiled in berms, primarily at locations shown in Exhibit E map, or moved directly to <br /> previously affected and graded areas for reapplication. <br /> a. Salvage an estimated 650 CY (in-place) soil from each acre. It is very likely that soils must be <br /> screened to remove larger stones, before stockpiling or reapplication, resulting in only 600 CY <br /> salvaged soil. <br /> Toner Ranch Pit 110c Application Exhibits Page 6 of 20 <br />
