C-93-024 Abatement Extension <br />Ms. Susan Burgmaier November 23, 1993 <br />CDMG <br />1313 Sherman St. <br />Room 215 <br />Denver, CO 80203-2273 <br />Dear Ms. Burgmaier, <br />Enclosed, please find three copies of a revised page for Appendix <br />4.6-M of the Edna Mine permit (C-80-001). This page has been <br />altered to satisfy the Division's concerns regarding the 1st and <br />4th quarter monitoring exemptions on the check dam structures <br />referenced in the revision. <br />The removal of the 1st and 4th quarter monitoring exemptions <br />granted in 1985 on the sediment pond embankments will be addressed <br />soon in another Minor Revision. This matter was also mentioned in <br />your letter, November 16, 1993. This revision will be submitted to <br />the Division prior to the deadline for 4th quarter monitoring so <br />that the requirement for inspections in each quarter can be met. <br />P&M also formally requests, via this letter, an extension to the <br />abatement time for NOV C-93-024. The abatement of this violation <br />called for submitting a Technical Revision to address drainage on <br />the Goat Trail and implementation of that plan. The T.R. for the <br />Goat Trail has been approved and several of the design structures <br />have been completed. The mine, however, is now receiving severe <br />winter weather and the ability to complete the remaining items is <br />doubtful until spring. For this reason an extension on the <br />abatement time is requested until the area can be safely accessed <br />with the necessary equipment. At your request, I have also <br />enclosed pictures of the areas where work has been done on the Goat <br />Trail plan. The snow cover was about 8 inches deep in the area <br />when the pictures were taken so there is not a great amount of <br />detail shown. <br />Should you have any questions regarding these matter, please <br />contact me at the Edna Mine site. <br />Sinc ely, <br />~~'-~~ <br />David Beverlin <br />Resident Engineer <br />
