AWES, LLC <br /> 2.4 Drawdown/Mounding Modeling <br /> Water level data will be used for drawdown and mounding analyses. The average of monthly water level <br /> data over a one year period will be input into the geostatistical software package Surfer'.Variations in pre- <br /> mining water levels will be presented on a two dimensional contour map and will be compared to <br /> numerical predictions and will be provided to the Division in an annual report which will be delivered <br /> during the first quarter after each sample year.All data and methods will be presented in the report. <br /> 2.5 Contingency Plan and Abatement <br /> As mine dewatering will create a groundwater sink it is highly unlikely that changes in groundwater quality <br /> will occur due to mining activities. As water levels will be measured on a monthly basis unanticipated <br /> groundwater drawdown can be predicted and evaluated for possible injury to off-site well owners. The <br /> extent of any abatement will be determined by negotiations with affected parties. <br /> 3_0 ORGANIZATION AND STAFF ASSIGNMENTS <br /> 3.1 Project Personnel <br /> Ms. Tana Kersting of Raptor will serve as field coordinator and will be responsible for obtaining water levels <br /> and will perform or supervise water quality sampling. Mr. Garrett Varra of Raptor will provide senior review <br /> of field and analytical data and will serve as project coordinator. <br /> 3_2 Subcontractors <br /> Subcontracted services for this project will include Technology Laboratories, Inc., of Fort Collins, Colorado <br /> who will perform analytical services. <br /> 4.0 OVERVIEW- QUALITY ASSURANCE/QUALITY CONTROL <br /> Quality assurance (QA) is a management system for ensuring that all information, data, and decisions <br /> resulting from the project are technically sound and properly documented. Quality Control (QC) is the <br /> functional mechanism through which quality assurance achieves its goals. Quality control programs, for <br /> example, define the frequency and methods of checks, audits, and reviews necessary to identify problems <br /> and dictate corrective action to resolve these problems, thus ensuring data of high quality. Thus, a QA/QC <br /> program pertains to all data collection,evaluation,and review activities that are part of the project. <br /> The use of qualified personnel for conducting various portions of the project is of paramount importance to <br /> an effective QA/QC program. This pertains not only to qualified CA/QC specialists, but also to specialists in <br /> other fields, including hydrogeologists, air quality specialists, soil scientists, analytical chemists and other <br /> scientific and technical disciplines. The project manager should ensure that qualified specialists, primarily <br /> individuals with the proper education, training, and experience, including licensed or certified professionals, <br /> are directing and performing the various project activities. The same general principles apply to selection of <br /> contractors and/or outside laboratories. <br /> Another important aspect of the QA/QC program is the communication between the CA/QC organization and <br /> the project manager. Regular appraisal by the project manager of the quality aspects related to the ongoing <br /> project data-gathering efforts provides the mechanism whereby the established objectives may be met. <br /> CA/QC procedures should provide details relating to the schedule, information to be provided, and the <br /> mechanism for reporting to the project manager. Reports to the project manager should include: <br /> 3 <br />
