SCC instituted in 1995 a new monitoring site numbering system for its <br />new Paradox TM water quality database. This new system is detailed in <br />Table A. For convenience sake, this table has been placed at the end of <br />the Table of Contents (see previous page). In addition, Table 3, Summary <br />of Ground Water Monitoring Wells; Table 8, Summary of Surface Water <br />Monitoring Sites; and the Table of Contents of Appendices B through D <br />have all been revised to correlate the old site (and map) name to the <br />new (Paradox) computer name. The new computer name will be used <br />throughout the following text. <br />Meteorological Data <br />There is no met station in the new Seneca II permit area. Data from the <br />National Climatic Data Center's Hayden Station is used here to evaluate <br />the precipitation trend. These data are provided in Appendix Al. <br />Precipitation data is summarized on Table 2. For this year, 12.80 inches <br />of precipitation was measured, which is 4.54 inches (26 %) below the <br />1971 -2000 average, 17.34 inches. All months except November, February, <br />July and September were below average. Snowpack runoff, as estimated by <br />totaling November through March precipitation values, was 5.35 inches, <br />which was 1.83 inches (260) below the 1971 -2000 average, 7.18 inches. <br />Ground Water <br />Water Levels. Water level data are presented in Appendix B. Water level <br />reports for data collected since 2005 are presented immediately after <br />the water level hydrograph of all historic data for each respective <br />well. By presenting all historic data, trends related to seasonal and <br />annual variability and possible mining related impacts are more clearly <br />evident. Table 3 (Summary of Ground Water Monitoring Wells) is presented <br />as a reference for the reader. The old ground water monitoring program <br />is presented on pages 7- 341/342 of the Seneca II PAP. The new program is <br />provided in the PR -02 package (Volume 14) on page 2.04.7 -2. Water level <br />measurements obtained in non - flowing wells are taken with water level <br />indicator, or in the case of a few shallow alluvial wells, directly from <br />VA <br />
