monitored in the spring season. The current surface water and spring <br />monitoring program is presented in Table 15 -9 of the Yoast Mine PAP. <br />All surface water data collected during this reporting period are <br />provided in Appendix D. Data for each site begins with a flow hydrograph <br />of all historic data (plus an annual hydrograph for NPDES sites), <br />followed by a listing of individual water quality and quantity data for <br />the current water year, and followed by remarks if present. This is <br />followed by a TDS regression plot using the LOWESS method (see the <br />Ground Water Quality section). <br />A statistical report representing baseline (i.e., premining) data for <br />each site downstream of mining (when available) is provided in Appendix <br />D1 of the 2010 AHR. On this statistics report, "censored data" refers to <br />analytical values that were below the detection limit, which were <br />censored from the min /max /mean calculations. The time frame for baseline <br />conditions is listed under "conditions specified" at the bottom of each <br />page. <br />Sage Creek <br />- Site YSSF3. This site exists on Sage Creek upstream of all potential <br />Yoast Mine discharges. It displays a recently stable TDS trend. This <br />site was dry during the October visit this year, was flowing in April, <br />August, and September. <br />- NPDESI2. Mining in this basin began in 2000. Reconstruction of the <br />water augmentation Pond Y1 (Site YSSF2) was completed on September 13, <br />1999. It is now referred to as Pond 012 (NPDESI2). This pond began to <br />flow again (after reconstruction) in April 2000. Flow at this pond is <br />continuous. The average flow value for this year was 0.1151 cfs, which <br />was 25% greater than the historic (2000 -2012) average for Pond 012, <br />0.0924 cfs, and was 11% less than the Pond Y1's historic (1991 -1999) <br />flow value, 0.1293 cfs. The timing of when flow values are collected <br />affects these averages. A statistical summary of baseline chemistry data <br />0 <br />
