All slopes above the water line will be reduce3 to 3:1 <br />maximum, for stability and ease in mechanized revegetation. <br />This applies to all pond perimeters, except the south bank of <br />the West Pond. That bank slope will be kept at 2:1 and seeded <br />by hand, to help protect the large trees which are now there. <br />2. Within the "new" area, in Stage I, where the slurry pumping <br />and bowl were proposed, all operations are now regarded as <br />only tentative. No operations will occur there, except for <br />two roads crossing that stage, connecting the emtrance to <br />Stage III, and connecting Stage IV to V. These amount to <br />about 1 acre of disturbance. The roads in Stage I will remain <br />after reclamation. No bond figures are now included in the <br />grand total for reclaiming any operations in Stage I. When <br />excavation or other activities are planned to occur there, an <br />appropriate increase in bond amount should be made to cover <br />that reclamation. <br />3. All topsoil and overburden related to the excavation of the <br />pond in Stages II and III will be pushed to the outer margins <br />of those stages, for simpler backfilling and replacing. These <br />materials will not be mass moved to Stage I. <br />As a final item, please send me an update of how you are F~roceeding <br />with approval of the substitute water supply plan, plus any recent <br />written dealings with the local farmers who originally expressed <br />concerns with dust, and also from the City of Aurora, who is/was <br />obligated to successfully revegetate the "new" parcel. <br />Please review the enclosed bond calculations, and let me know at <br />your earliest convenience whether the revised figures meet your <br />approval. If you have any questions or corrections concerning this <br />amendment, feel free to contact me. <br />Sincerely, <br />gld b ~'~L <br />Bob Oswald <br />Environmental Protection Specialist <br />enclosures: bond calculations <br />b:\dmgcor04.95/6-7 <br />
