• <br />Mr. Harty Ranney <br />December 1, 1995 <br />Page 2 <br />C~ <br />8. The statement that trace metals in the surface water improve downstream is supported in the AHR <br />documents when comparing mean values of aluminum, iron and manganese at stations S-1 (upstream) and <br />S-3 (downstream). Over the period of record, mean values are slightly higher upstream of the mine opera- <br />tion. This statement has been added to revised Page 2.04-18b. <br />9. Kaiser has written the last paragraph on Page 2.04-34 to indicate that "reference areas for the portion of <br />the mined area which will be reclaimed to rangeland and irrigated pasture will receive the same <br />management as the reclaimed areas." If Kaiser wishes to graze the area before the last two years of the <br />liability period, a specific request will be submitted to the Division for approval. Page 2.04-34 has been <br />modified to indicate this approval. <br />10. Exhibit 5, page 3 describes the techniques used during the 1990 study. Any further vegetation <br />investigations would be conducted using techniques approved by the Division. It is Kaiser's currently <br />standard practice to utilize a Division approved ocular sighting device which is mounted on a tripod with <br />a leveling apparatus. Use of this tool will assure objectivity of any future sampling. <br />11. The hydrologic monitoring schedule has been added to the permit document as Table SA. <br />12. Stakes have been installed in each of the sediment ponds to determine sediment levels. <br />13. Page numbers have been added to Tables it and 12 and the page number on Table 13 has been corrected <br />(see attached revised pages). Figure 5 on page 2.06-3 has been deleted from the permit document. <br />14. Information in the Appendices has been reviewed. The information in Appendix 7 concerning ponds and <br />ditches is in the process of being revised and will be submitted under separate cover at a later date. <br />Bonding Summary. A rider listing the new corporate name will be submitted under separate cover at a later <br />date. <br />Should you have questions or need additional information concerning this request, please do not hesitate to <br />contact Mr. Mike Keegan or Ict me know. <br />Sincerely, <br />~~ Q~ ~ <br />Jerry H.
