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 />A new NPDES permit was issued for Seneca Coal Company on September 26, <br />2006. It went into effect November 1, 2006. Quarterly monitoring <br />requirements went into effect in the first quarter of 2007. See the <br />Seneca II-W PAP, Appendix 15-4, for the new permit. <br />Due to the closing of the Seneca II-W Mine, SCC requested a reduction in <br />monitoring frequencies of streams, springs and wells. TR 58 was approved <br />on June 29, 2007. The changes are as following. <br />For ground water monitoring wells, the frequency of water level <br />measurements has been changed from tri-annual to semi-annual (May/June <br />and September/October). Water quality sampling of alluvial well GW-S2W- <br />21A (Sage Creek) was changed from triannual to semi-annual. Water <br />quality sampling of bedrock wells was changed from semi-annual to annual <br />(May/June). Water quality sampling was discontinued at wells GW-S2W-16OV <br />and 16W. For stream sites, monitoring at SW-52W-SG5 (Dry Creek), SW-S2W- <br />FG1 (lower Hubberson Gulch)-and SW-S2W-FG4 (Sage Creek) was changed from <br />monthly to tri-annual (spring runoff, post-runoff and baseflow). For <br />springs and spoil springs, monitoring was changed from semi-annual to <br />annual (May to July). All monitoring at Springs S-23 and 5-48 was <br />discontinued. <br />Meteorological Data <br />Precipitation data is collected from a Belfort Weighing Bucket Rain Gage <br />situated adjacent to Surface Water Site SW-S2W-FG1. Data for this year <br />may be found in Table 1. Total monthly precipitation data collected at <br />this site since Water Year 1990 are presented in Table 2. The Seneca II- <br />W precipitation gage measured 16.75 inches this year. This value is 1.05 <br />inches (60) below the 1990-2007 average of 17.80 inches. All months <br />except October, February and Septen~er were below average. Temperature, <br />wind speed, and direction data from the Seneca II-W Meteorologic Station <br /> <br />
