• <br /> <br />Section III - Status of Stipulations <br />(continued) <br />Stipulation No. 19 <br />Colorado Westmoreland, Inc. is directed to complete Phase III of the <br />stability analysis and redesign of the final reclaimed configuration of <br />the surface facilities of the Orchard Valley Mine, as described in the <br />various letters of proposal from Merrick & Company and Geohydro <br />Consultants included in Volume 10 of the amended application. The scope <br />of Phase III shall include the utilization of the findings and <br />recommendations of Phase II to complete final design of the proposed coal <br />processing waste pile at the Orchard Valley Mine. This project shall <br />proceed in a timely fashion to completion by June 30, 1982. The Division <br />shall be kept informed by monthly letter of the progress of this task by <br />the operator. Upon finalization of the coal processing waste pile design, <br />the Orchard Valley Mine plan shall be appropriately amended. <br />Resolved: The Phase III stability analyses of the waste rock pile may be <br />found in Volume 6A of the permit application and were completed between <br />1982 and 1984. <br />Stipulation No. 20 <br />The applicant must, within one year of the permit issuing, submit a plan <br />to the Division for restoring the essential hydrologic functions of the <br />Stevens Gulch and north fork of the Gunnison alluvial valley floors. This <br />plan shall identify the essential hydrologic functions of these two <br />alluvial valley floors and must show in adequate detail how the essential <br />hydrologic functions will be restored. <br />Resolved: CWI submitted a plan to restore the essential hydrologic <br />function of AVFs on August 8, 1982 and September 7, 1982. This was <br />approved by the Division on December 10, 1982. <br />Stipulation No. 21 <br />The operator shall submit to the Division an annual report of inflows, <br />discharges, and consumption of water within the mine. This report is to <br />include a mine workings map showing the location and quantity of inflows; <br />a table keyed to the mine map which shall contain the source <br />(i.e. fault, fractures, etc.), quantity, duration and quality (i.e. pH, <br />electro-conductivity and temperature) of all measurable inflows; a table <br />containing records of water imported for use within the mine; a discussion <br />of the water balance within the mine; and finally, a projection of <br />hydrologic impacts of mining in the upcoming year. <br />Resolved: This stipulation is currently found as Stipulation No. 29 in <br />the 1988 document. <br />
