Parkdale Project • III IVIIIIIIIIII III ~ Reclamation Permit <br />S/ x <br />Exhibit D -Mining Plan <br />1.0 Introduction <br />The proposed Pazkdale Project includes mining from three resource areas which are: <br />1) aggregate from the gravel bar, 2) granite from a quarry, and, 3) sandstone from a <br />small quarry, processing the mined material, and loading it for shipment primarily by rail <br />with local deliveries by truck. Mining operations are planned for one shift per day. A <br />second shift will be added during periods of heavy seasonal demand. Maintenance and <br />rail loading may be scheduled anytime. Truck loading will be limited to 12 hours per <br />day and no truck shipments will be scheduled during the period from noon on Saturday <br />until 6 a.m. Monday. The project has been designed to utilize natural topographic <br />screening to separate operations from Highway 50 to the extent possible. These activities <br />are described below and the overall layout of the project is shown on the Mining Plan <br />Map. <br />Initial activities at all disturbance sites will include topsoil salvage and placement into <br />stockpiles. Generally, some topsoil is available for salvage from the nearly level <br />processing areas while little is available from the yuarry sites. Disturbed sites will be <br />graded to be free-draining to small sediment ponds which will discharge via infiltration <br />and through check danis. These erosion control measures will be maintained for the life <br />of the project. Mining activities at each of the areas is described below. <br />1.1 Gravel Bar Aggregate Pit <br />The Gravel Bar Aggregate Pius are located south of Tallahassee Creek and north of the <br />Arkansas River. Course aggregate, decorative stone, sand, road base course, surfacing <br />and drainage fill aggregate products will be produced from these borrow pits as a part of <br />initial project mining activities. <br />Approximately 14 pGres of aggregate borrow pits will be developed at this site to meet <br />production requirements during the first 5 years of operation. Approximately 1,000,000 <br />cubic yards will be developed from this resource during the first flue years of project <br />operations. Later phase project needs ma exult in disturbance to an additional 41.2 <br />acres to develop an additional 3,000,000 cubic yards of aggregate. The pits will be <br />developed sequentially as product is required to meet market demand. The configuration <br />of borrow pits is shown on the Mining Plan Maps for Gravel Area A and B. <br />The shallow Gravel Bar Aggregate Pits will be mined by a combination of tracked and <br />rubber-tired heavy construction eyuipment including scrapers, dozers, end-loaders and <br />haul trucks. Minor amounts of overburden, where present, will be loosened where <br />necessary by ripping and it will be removed and transported by either scrapers or a loader <br />and haul truck operation. Where pos~ble,overburden will be directly placed eliminating <br />creation of stockpiles and double handling. All overburden will be placed into fills or <br />otherwise used in post-mining topography shaping. Following mining of an area, [hat <br />area will be concurrently reclaimed by grading, placement of topsoil and seeding. <br />r~- <br />~~,Z <br />~~ - <br />
