INTRODUCTION <br />Mining has been conducted on this site since before 1976, with operations being continuous <br />since then. Asphalt Paving Co. is amending the 112c reclamation permit for its Ralston Quarry <br />(M- 1974 -086) to incorporate a revised post mine land use and reclamation plan. The existing <br />permit area of approximately 271.61 acres is located in Jefferson County. The operation is <br />accessed via a private access road that connects to State Highway 93, to the east of the operation. <br />It is approximately 3.5 miles north of Golden, CO, and 0.5 miles west of the City of Arvada, in <br />Jefferson County. The site, in relation to the Cities of Golden and Arvada, is shown on Map B -1. <br />The mining operation is in a basalt formation overlaying uplifted Pierre shale. Topographically, <br />the permit area encompasses a singular ridge of the basalt separating a pair of reservoirs. The <br />disturbed area for the Ralston Quarry is 209 acres, and includes all of the mining area, berms, <br />and roads. The permit boundary is shown on Map C -1 and is 271.61 acres. <br />The permittee and operator for this site is Asphalt Paving Co. Asphalt Paving Co. leases the <br />entire property from Keller Family Limited Partnership, LLLP. Property lines obtained from the <br />property owner are shown on Map C -1. <br />An amendment approved in 1994 expanded the operation slightly. This 2014 amendment is to <br />change the post mine land use for the bulk of the site, and to clarify the location of a fenceline as <br />it relates to the permit boundary. The site will be reclaimed to the land uses of a water reservoir <br />and rangeland. The topography of the reclaimed land is shown on Map F -1. All maps are found <br />in Appendix 4. <br />Ralston Quarry, February 2015 i -1 <br />
