WORWEST <br /> COR PORAT ION <br /> 1 INTRODUCTION <br /> 1.1 PROJECT DESCRIPTION <br /> Transit Mix Concrete Co. (Transit Mix) is proposing a mining plan to excavate aggregate <br /> quality granite material at Hitch Rack Ranch Quarry located southwest of Colorado <br /> Springs, Colorado. The mining plan project area (Project Area) covers an area of 399 <br /> acres in the Little Turkey Creek watershed, Figure 1-1. The purpose of this monitoring <br /> plan is to characterize surface water and groundwater conditions prior to mining <br /> development. Monthly surface water and quarterly groundwater monitoring will be <br /> conducted for a length of approximately 15 months. <br /> Two (2) surface water monitoring locations were established on Little Turkey Creek. One <br /> upstream of mining operations and another downstream of the mining operations, all <br /> located within the Hitch Rack Ranch property boundary. Surface water monitoring will <br /> include the collection of water samples for laboratory analysis, field parameters, and <br /> streamflow from both locations. Water quality samples will be collected monthly, and <br /> flow measurements will be collected at least monthly. The locations will be instrumented <br /> with a pressure transducer to record flow levels, and these flow levels will be calibrated to <br /> the monthly flow measurements. An additional flow monitoring location, near the plant <br /> area, has also been established on the creek. GPS coordinates, elevation, and photo <br /> documentation will also be collected at each surface water location and recorded in the <br /> field book and on the field forms located in Attachment A. <br /> Six (6) groundwater wells and one piezometer were installed with three completion zones <br /> targeting the alluvium, shallow bedrock formations, and deep bedrock formations. Two of <br /> the wells are proposed for compliance monitoring: one (1) well is located upgradient of the <br /> mining operations and one (1) well is located downgradient of the mining operations, but <br /> upgradient of the East Fault, all within the Hitch Rack Ranch property boundary. The <br /> middle completion of these two wells will be used for compliance monitoring. <br /> Groundwater monitoring will include the collection of water samples for laboratory <br /> analysis, field parameters, and well water level measurements. Water quality samples will <br /> be collected from the two compliance monitoring zones on a quarterly basis for the <br /> duration of the monitoring period (15 months), and the other completion zones will be <br /> monitored a single time to establish baseline conditions. Additional samples may be <br /> collected from the other completion zones depending on the initial water quality and water <br /> level results. These additional samples may also include variations in the analyte list to <br /> include additional parameters or remove parameters that have been "non-detect" or proven <br /> TRANSIT MIX CONCRETE CO. <br /> SURFACE WATER AND GROUNDWATER MONITORING PLAN <br /> 1-1 <br />
