a <br />After their review of last year's Seneca II AHR, the CDMG made several <br />comments in a letter dated September 2, 2005. Following is SCC's <br />response to each item. <br />1. A request was made to establish ground water points of compliance. <br />SCC will attempt to submit such a technical revision in 2006. <br />2. This item dealt with changes to the hydrology monitoring program in <br />TR-36. TR-36 was approved on January 26, 2005. Monitoring a certain <br />wells was changed. Monitoring at Site SW-S2-1 was changed to triannual. <br />Monitoring at Fish Creek was changed to May to July. Those changes are <br />described in detail on pages 7-378 and 379 of the permit. No further <br />response is necessary here. <br />3. TR-38 (approved May 20, 2005) made changes to the surface and ground <br />water parameter lists and changed the monitoring frequency at Spoil <br />Spring 1 to triannual. Those changes are described in detail on page 7- <br />379 of the permit. The appropriate tables in this AHR have been revised <br />to reflect those changes. <br />4. The new CDPHE ground water standards have been incorporated into this • <br />AHR as requested. <br />5. - As requested, a mention of the new spillways at Ponds 004 and 008 <br />will be made in this AHR. <br />6. In regards to the surface water quality discussions the changes <br />suggested by the CDMG (Spoil Spzings 7 and l0A and water quality <br />standards) will be incorporated into this permit. <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. Temperature, wind speed and <br />direction data are presented in Appendix B of the Seneca II-W AHR.
