EXHIBIT D <br /> MINING PLAN AND TIMETABLE <br /> Amendment 01. This amendment will cover five (5) changes that <br /> will be discussed below the list : <br /> • Permitted acreage increase - Increase permitted (and affected) acreage for the entire <br /> permit area by a total of 26.62 acres - from 641.35 to 667.97 acres <br /> • Phase 1 - Increase acreage by adding 9.80 acres along the west side, for a new total area <br /> of 90.31 acres <br /> • Phase 2 - Increase acreage by adding 8.92 acres along the west side, and by adding the <br /> 25.38 acres of Phase 2A into Phase 2 (changes due to oil and gas), for a new total of <br /> 189.83 acres <br /> • Phase 3 - Increase acreage by adding 7.90 acres for a conveyor crossing over the <br /> transportation corridor that separates Phase 3 and Phase 4, for a new total area of 81.20 <br /> acres. <br /> • Underdrain - Revise reclamation plan to include the underdrain built between Phase 1 and <br /> Phase 2 <br /> • Revise the reclamation practices around the reservoir perimeters to allow for a band of <br /> gravel to be left between the high water line and the slurry wall. <br /> The methods described and approved in the original mining <br /> and reclamation plans will remain unchanged unless discussed in <br /> this text . We have included all exhibits for continuity of the <br /> file and have marked those Exhibits with NO CHANGE if they are <br /> the same as originally submitted. Were appropriate, the MININGAND <br /> RECLAMATION PLANS AND TIMETABLES have been revised to reflect the proposed changes. <br /> The amendment will follow MLRB Rule 1.8 and Colorado Revised Statutes, 1992, <br /> Section 34-32-112(8). <br /> EXPANSION- Phase 1 and Phase 2 - are being increased by a total of <br /> 18 . 72 acres the along the west side in order to address the <br /> underdrain installation and add the associated permit boundary <br /> extension. When reviewing the existing permit for this amendment, <br /> the operator decided that moving the west permit boundary of <br /> Phases 1 and 2 farther to the west would prevent any additional <br /> disturbance outside the permit area. The western permit boundary <br /> will now generally follow the west side of an existing <br /> agricultural access road, which is elevated. Portions of this <br /> additional permit acreage may be disturbed, and if so will be <br /> revegetated. <br /> Phase 2 is also expanding due to incorporating Phase 2A into <br /> its total area.
