This TR <br />established ground water points of compliance (GWPOC) for the Seneca II <br />Mine. Attachment 7-3 of the Seneca II PAP provides details of this TR. <br />Well SGAL70 (GW-S70-A) is the GWPOC in the Grassy Creek basin. Well <br />SFAL72 (008-AU-3) is the GWPOC in the Fish Creek basin. An analysis of <br />these two GWPOC's is provided in the ground water section of this AHR. <br />Meteorological Data <br />Precipitation data was obtained at the Seneca II Mine using a Belfort <br />Weighing Bucket Rain Gage. Daily precipitation data for this year are <br />presented in Table 1. Total monthly precipitation data collected since <br />1981 are presented in Table 2. Where indicated, data from the U.S. <br />Weather Service - Hayden Station were used. The Seneca II precipitation <br />gage measured 15.19 inches this year. This value is 2.97 inches (16%) <br />below the 1981-2009 average. Temperature, wind speed and direction data <br />are presented in Appendix B of the Seneca II-W AHR. The Seneca II-W <br />Mine Meteorological Station located approximately seven miles southwest <br />of the Seneca II Mine. Climatic conditions are similar between the two <br />mines. <br />Data from the National Climatic Data Center's Hayden Station is used <br />here to evaluate the precipitation trend. These data are provided in <br />Appendix B of the Seneca II-W AHR. For this year, 20.03 inches of <br />precipitation was measured, which is 2.69 inches (16%) above the 1971- <br />2000 average. The months of December, January, March, April, May and <br />June were above average. Snowpack runoff, as estimated by totaling <br />November through March precipitation values, was 10.17 inches, which was <br />2.99 inches (42%) above the 1971-2000 average. <br />2 <br />i <br />d
