6.4.5 EXHIBIT D-Extraction Plan <br /> north-west of the existing Bans Ditch as it courses winds north of <br /> the Big Thompson River. <br /> Plant activities will require a wash plant and attending wash pond to recycle <br /> wash hater and receive discharge silts and other reject fines from the washed <br /> product_ Plant and Wash Pond areas are identified on Exhibit C-2: Extraction <br /> Plan Map. The wash pond will function as recycling wash water and receiving <br /> basin for reject fines for the intended Plant/Processing activities. Since the <br /> basin functions in a closed system, it will not require dewatering_ <br /> once the mash pond is established, stet plant operations can be created and <br /> join any dry plant activities in progress. Dry Plant operations can be readily <br /> established since water is not integral to their operations_ once established, <br /> wash pond water will function as a closed system Settled materials from <br /> wash Ponds will be utilized as product or for reclamation as desired_ <br /> Plant equipment will include, but is not limited to, a crusher, screens, and <br /> conveyors, scale house and scale, and attending equipment. Resulting <br /> stockpiles of pit run and processed products may be temporarily stock-piled <br /> here with processed stockpiles, or combined as needed, until transported to <br /> market. <br /> Division Second Adequacy Comment <br /> • More detail is needed regarding the conveyor. Please provide the size of the <br /> conveyor. Also, provide the dimensions of pads and other foundations that will be <br /> used for this structure and provide an estimate of the total volume of concrete that <br /> will be used. Related to this, Exhibit L will need to be updated to include the cost of <br /> dismantling the conveyor. <br /> • Please describe the measures to be taken to prevent material from overtopping <br /> the conveyor system and falling into the Big Thompson River. <br /> Raptor Materials Second Adequacy Response <br /> The First Adequacy response provided has been enhanced and added to revised <br /> Exhibit D as requested including additional discussion on how material originally <br /> placed by the river will be prevented from falling from the conveyor back into the <br /> river (p23, Footnote 9). <br /> 25) In the section Plant Site Development & Operations, text should be added <br /> regarding the control of prairie dogs. Will they be relocated? <br /> 321Pagc <br /> Correspondence to the Colorado Office of Mined Land Reclamation —Reply to Rob Zuber,EPS—Adequacy Letters of 24 June and 5 <br /> August 2022;in the matter of the Two Rivers Sand,Gravel and Reservoir Project—M2022-013. <br />
