F #]01 ulog~ <br />Durango, CO 81301 <br />Re: Yule Quarry File No. M-99-058, Second Adequacy Review ofNew 110 Permit <br />Dear Bob: <br />Thank you for your letter of July 6 regarding the above subject application. The following <br />paragraphs are responses to your letter. I have also updated the permit application itself to reflect <br />these responses and enclosed a draft copy for your review. <br />Exhibit C - Minine Plan <br />Your paragraph four: Throughout the life of the operation, Sierra plans no dumping in any area <br />that might cause further offsite damage, specifically in the area directly east of the main portal. I <br />have revised the northern boundary of the affected area to delete this area, as there aze no plans to <br />perform any mining or reclamation activities there. It was originally included without thought as <br />to whether there would be any activity in the area. Sierra will post signs on the east side of the <br />road in this area to prohibit dumping so that there is no misunderstanding by Sierra employees. <br />Your paragraph five: Discussion of this issue is provided below under Exhibit G -Legal Right to <br />Enter. <br />Your paragraph seven: As stated, Sierra may elect to move the generator trailer from its current <br />location on the surface to a location underground. Should this occur, Sierra will use an existing <br />buried steel fuel supply line from the existing surface fuel tank through the existing utility tunnel <br />(just south of the main quarry portal). A final underground location for the generator has not <br />been chosen. The relocation of the generator underground will result in a shorter run of the <br />buried fuel supply pipe than exists currently. I have also added one hour of large backhoe time for <br />removal of the fuel supply line upon reclamation. <br />Your paragraph eight: Approximately 1001ineal feet of chain link fencing exists in the quarry <br />entries where IMP fencing has been removed. Sierra will maintain these fences and add up to 500 <br />lineal feet of temporary lodge pole pine and barbed wire fencing to prevent public access to <br />
