<br />additional geochemical testing, Sequential Batch Tests, and Humidity Cell Tests. Subsequent <br />• testing of the tailings material submitted on a quarterly basis also provides information on the <br />geochemical characteristics of the mined materials. <br />Technical Revision 026 presents additional geochemical chazacterization for geologic materials <br />affecting the quality of groundwater flowing from the West Pit (Section 3.2). The focus of the <br />additional characterization was to identify the sources of elevated constituents ip the West Pit <br />groundwater and to estimate the length of time necessary to reduce the concentrations of <br />constituents in the West Pit groundwater. The water management plan outlined in TR-026 was <br />designed to prevent the flow of groundwater from the West Pit into the adjacent Rito Seco <br />alluvial aquifer. <br />14.0 CONSTRUCTION SCHEDULE <br />Construction schedules for development of the environmental protection facilities in the West Pit <br />aze contained in the individual engineering design reports that have been submitted to the <br />Division. <br />• 15.0 QUALITY ASSURANCE/QUALITY CONTROL <br />Appropriate Quality AssurancelQuaiity Control (QAIQC) has been, and will be, performed <br />during the construction of all environmental protection facilities. Specific QA/QC programs for <br />construction of each environmental protection facility in the vicinity of the West Pit aze <br />described in the engineering design reports that have been submitted to the Division. As-built <br />reports for all facilities have been, and will be, submitted to the Division upon completion of <br />construction. BMRI will include QA/QC procedures along with any revision request to the <br />Division for approval prior to construction of all future construction or work on the <br />environmental protection facilities. <br />16.0 PLANT GROWTH MEDIUM <br />Most, if not all, of the top and subsoils that will be salvaged have been salvaged. Much <br />successful reclamation has already occurred on site. The soil types, depth available for suitable <br />• reclamation soils, and a map showing the soil units aze presented in Exhibit I and Section E.2.1 <br />Basle Mountain Resowces, /nc.
