Exhibit D- Extraction Plan <br />Method of mining is presently dry, with discharge of waters conducted under an <br />approved Colorado Dept. of Health discharge permit. Extraction utilizes, but is not <br />limited to, diverse heavy equipment; including, backhoes, scrapers, excavators, dozers <br />and related heavy equipment. A grader and water truck maintain access throughout <br />operations. Access is clearly indicated under Exhibit C-1: Existing Conditions and <br />Exhibit C-2: Extraction Plan Map. <br />Primary access is approximately 657.0± feet east of Ash Avenue behind a commercial - <br />industrial lot owned and controlled by Varra Companies, Inc. The lot itself is flanked on <br />its western boundary by Ash Avenue. Access from the permit boundary will be through <br />the existing lot. The commercial industrial lot is surrounded by other industrial lands <br />and uses when turning from that lot either north or south onto Ash Avenue itself. <br />Wet and/or dry plant processing operations will occur near the eastern permit boundary <br />on previously affected lands comprising the last area of extraction identified as Tract A <br />on Exhibit C-2: Extraction Plan Map. The specific plant operations will be clarified by a <br />later Technical Revision to the Division, but are generally comprised of portable <br />equipment. A small wash pond may be established within Tract A or an adjacent <br />existing pit, or as otherwise identified in the correlated Technical Revision. <br />Materials may be processed and scaled at the adjacent Durham Project until similar <br />facilities are established within the approved permit boundary. Provisions for a <br />materials processing plant, a concrete and/or asphalt batch plant, and periodic use of <br />recycling facilities and related plant, remain a necessary inclusion to operations under <br />this permit. Any material processing facilities, recycling facilities, recycling plant, or <br />concrete and/or asphalt batch plant locations will be determined and identified in a later <br />Technical Revision to the approved permit, and are mentioned for purposes of <br />establishing these activities as approved uses under this submittal. Additionally, <br />adjacent lands may have asphalt or concrete batch plant operations serviced by the <br />permit, but will occur on adjacent lands under a separate approved municipal permit <br />with the City of Greeley, and such operations and attending stockpiling or other surface <br />disturbances or features should not be considered part of this permit or extraction <br />activities requiring permitting under the Act. <br />Known structures and landowners, including above and below ground utility owners, <br />located on and within 200± ft. of the permit boundary are shown on Exhibit C-1: <br />Existing Conditions and Exhibit C-2: Extraction Plan Map. Exhibit S — provides <br />certification from a registered professional engineer that these structures will not be <br />harmed by planned operations; nor has any evidence of harm evidenced itself over the <br />nearly 60± years of operations at the adjacent Durham Project. <br />A 1600± linear foot standard morphing extraction front is comprised of a 1.25H:1V face <br />along an approximate 800-1200± linear foot advancing; wall with trailing side slopes up <br />Varra Companies, Inc.
