for potential effects on cottonwood trees and other riparian vegetation along the Cache la <br />Poudre River corridor. Through the well monitoring program, pre-mining groundwater <br />elevations, flow patterns across the property, and seasonal fluctuations will be documented. <br />Well Inventory <br />A well inventory for the site and adjacent areas was conducted to identify wells near the <br />project. The inventory included a review of the following records: <br />a) Well records (Registered Wells) on file with the Colorado Department of Natural <br />Resources, Office of the State Engineer (SEO); and <br />b) Reported well records from Environmental Data Resources Inc. (EDR) - <br />(EnviroGroup, 2007). <br />Based on groundwater modeling results (Attachment G-2), the primary focus area for well <br />records encompassed a radius of 0.5 miles (2,640 feet) from the property boundary. This <br />radius was selected due the fact that simulated drawdowns from mine dewatering were less <br />than about 1.5 feet outside this radius. <br />The records search indicated that there are five permitted wells within 0.5 miles of the mine <br />property (Table 2 and Figure 2). Lafarge has completed a survey of these wells and well <br />owners to confirm the well locations and provide well owners the opportunity to have their <br />well(s) included in the monitoring program. <br />SEO requires a 600-foot well spacing agreement statement from the well owners who have <br />wells within 600 feet, at least six months prior to the commencement of mining of a <br />relevant phase. The records search indicated only one permitted well within 600 feet of the <br />proposed permit boundary. This well, identified below, is approximately 1000 feet from <br />the closest proposed mine excavation. <br />Permit: 51859 <br />Owner: Ed Orr <br /> 826 9`h Street <br /> Greeley, CO 80631 <br />Use: Irrigation (currently not in use) <br />Location: NW'/ SW'/ Sec 31, 6N 66W <br />The Parsons Mine is not expected to have any significant effects on this well due to the <br />following: <br />a) Primary mining/dewatering activities near the well are located north of the Cache la <br />Poudre River and the well is located south of the river. <br />b) Mining activities south of Cache la Poudre River are principally isolated from this <br />well by existing water storage reservoirs and the river itself due to its meander <br />pattern. <br />Lafarge West, Inc. - Parsons Mine 3 <br />Groundwater Monitoring and Mitigation Plan
