k. No refuse or acid forming or toxins should be mined. I. The boundaries established for the affected mining area shall be enforced in an effort to minimize any detrimental disturbances to the existing hydrologic balance with -in the permitted area. Storm run-off shall be mitigated with the use of a storm water rock filtration allowing for filtration and evaporation before moving off the affected area. Additionally, grading at the berms located throughout the permitted area will be sloped no more that 3:1 to mitigate the potential for heavy storm water run -off. m. Deposits will be processed: excavated, screened, and crushed on -site. Material screener(s) and crusher(s) are located on the Northwest area of the site. Pit run material will be extracted by Excavator then transported and fed (dumped) into the crusher and screener by Front End Loader. Screeners will separate the product by conveyor into processed material piles which are transported by Front End Loader to waiting trucks and /or stockpiles located on site. The operator will use no chemicals in processing the deposits. n. The primary commodities extracted include %" to 1" gravel, road base, and crusher fine material. Primary commodities are intended for use on county road projects, commercial and /or residential construction projects and state hi -way construction projects. Secondary commodities, if encountered, may include sand and large rock and may have diverse uses including light construction and landscape applications. o. Incidental products extracted by the operation will be intended for use as construction fill material. p. Not applicable. No explosives will be used in the mining operation. 6.3.4 EXHIBIT D- Reclamation Plan 1. Reclamation Plan: The Sharp Pit #2 is expected to end operation in June 2020. At that time the affected mining area is scheduled for reclamation to the proposed future use of the land; Pasture Land. a. During the mining operation overburden will be extracted and placed on the perimeter northwest boundary at an approximate depth of four to five feet. b. Reclaimed slopes are anticipated to be 3:1 throughout the pit area. c. The site will be re- vegetated in accordance to the grass seeding plan prepared January 18, 2013 by Cindy Schleining, Certified Conservation Planner with NRCS / Bent County Conservation District See attached Grass Seeding Plan. i. Plant thickness is anticipated to be 4" - the actual grass seeding preparation and variety of grass planted shall be in accordance with the established seed plan. ii. The soil preparation shall take place in the summer month's preceding fall 2020 when the grass seeding will commence. The soil will be include intensive seed preparation of up to 3 tillage operations then disked as needed to mitigate compacted conditions prior to seeding. Fall seeding will be done using Tractor and drill where possible and hand broadcast where unsafe tractor conditions exist. Manure shall be applied at a rate of approximately 25 ton per acre based on soil, weather and seed bed conditions at time of application. See attached Grass Seeding Plan. iii. The species scheduled for planting include Western wheatgrass, Blue grama, Russian wildrye, Little bluestem and Sand dropseed. The quantity of grass seed, pounds of pure live seed per acre, application rates and percentage mixes are specifically outlined in the grass seed plan See attached Grass Seeding Plan. iv. The soil will be include intensive seed preparation of up to 3 tillage operations then disked as needed to mitigate compacted conditions prior to seeding. Fall seeding will be done using Tractor and drill where possible and hand broadcast where unsafe tractor conditions exist. Sharp Pit #2 - Riverside Aggregates, LLC. April 23, 2013 Page 3
