<br /> <br /> <br />1-1 <br /> <br />Section 1 <br />Introduction <br />This baseline sampling and analysis plan (SAP) provides details on the surface water and groundwater <br />monitoring program that will be conducted at the Red Creek Quarry (RCQ) property under the Bear Creek <br />Quarry (M-1977-344) permit amendment. It was prepared by Brown and Caldwell (BC) on behalf of <br />HolcimUS (Holcim). The proposed RCQ mine will be an open-pit limestone quarry near Florence, CO. The <br />RCQ Property will consist of an open-pit limestone quarry to provide raw materials for the Holcim <br />Portland Cement Plant and is located west of Pueblo, Colorado including Sections 24 and 25 in Fremont <br />County and 19, 20, 29, and 30 in Pueblo County, Township 20 South, Range 68 West (Figure 1). <br />The surface and groundwater baseline monitoring program is part of the Colorado Department of <br />Reclamation and Mine Safety (DRMS) permit application process for RCQ. The analytes and method <br />detection limits selected for the surface water and groundwater baseline evaluation include biological, <br />inorganic, and radiological suites listed in the Colorado Water Quality Control Commission standards for <br />surface and ground waters. This monitoring plan incorporates existing well locations for groundwater <br />quality and establishes surface water monitoring locations for flow and water quality, as well as a Quality <br />Assurance Project Plan (QAPP) and field sampling methodologies. <br />1.1 Objectives <br />This SAP is designed to collect data to assess potential water resource impacts from future mining <br />operations conducted at the RCQ. Constituent loading to surface water and groundwater could occur <br />during future operations from stormwater runoff or groundwater seepage into mine pits and therefore <br />baseline data, prior to mining, is needed to evaluate that change. <br />The goals of the monitoring program include: <br />• Document the characteristics of surface water and groundwater prior to any mining to assist in <br />evaluation of the RCQ permit applications <br />• Obtain accurate and defensible data by following the site-specific QAPP (Appendix B) and standard <br />operating procedures (SOPs) (Appendix C) <br />• Provide accurate and complete reporting of potential future mining-related impacts to appropriate <br />regulatory agencies <br />This plan covers the monitoring program that will be implemented as part of the mine permitting <br />process. <br /> <br /> <br />
