1 Introduction <br /> The Natural Soda LLC (NS) site-specific Sampling and Analysis Plan (SAP) is a companion <br /> document to the Quality Assurance Project Plan (QAPP) (Appendix D). Policies and procedures <br /> specified in the NS QAPP will guide the sampling and analysis activities. The purpose of the SAP <br /> is to assist with groundwater aquifer characterization. NS has implemented this SAP to monitor <br /> for notable changes to groundwater conditions potentially influenced by solution mining and/or <br /> facility operations. The plan describes sampling and analysis protocols which are to guide <br /> groundwater sampling activities. These protocols are pursuant to requirements of federal and <br /> state policies and procedures. The groundwater sample collection program includes the design <br /> and implementation of the proposed sampling, sample collection and management, analytical <br /> methods, health and safety procedures, and quality assurance goals. Qualitative data acquired <br /> during the sampling and analysis events will be utilized to monitor groundwater quality. <br /> Sample collection protocols also apply to the periodic NS sodium bicarbonate barren fluid <br /> injection fluid (water injectate) sampling. In addition, the data are used in the development <br /> and implementation of remedial activities when deemed necessary by the BLM or the EPA. <br /> The general vicinity of the NS Lease area and monitor well locations are shown in Appendix A, <br /> Figure 1. Figure 2 in Appendix A shows the NS plant site and the monitoring wells located in <br /> Section 26. <br /> 1.1 Project Organization and SAP Distribution <br /> NS provides the administration for the SAP project. Daub & Associates, Inc. (Daub), located in <br /> Grand Junction, CO, provides guidance for the specific water quality sampling and sample <br /> analysis activities, which includes proper planning and implementation. In addition, Daub <br /> provides quality assurance (QA), oversight, and review. NS or a qualified contractor will <br /> conduct the sample collection as specified. An approved, certified laboratory shall analyze the <br /> samples and disseminate analysis results. The SAP shall be distributed to all pertinent <br /> personnel and agencies—administrative, technical and regulatory—involved with sampling and <br /> analysis activities. All pertinent personnel are responsible for familiarity with the contents of <br /> the SAP. <br /> 2 Purpose and Scope <br /> The purpose of the SAP is to provide a description of the media to be sampled, the work to be <br /> performed, the action level that is necessary, and the Applicable or Relevant and Appropriate <br /> Requirements (ARARs). This SAP pertains to groundwater and working fluid (water injectate) <br /> sampling and groundwater hydrostatic head measurements on the NS Lease.
