Colowyo Mine December 11, 2008 <br />TR-72 2 <br />on March 14, 2008. We sent out `completeness' notices on March 21, 2008 notifying interested <br />persons that Colowyo was proposing a change in the reclamation plan and requested comments. <br />We received DOW's comments on April 14, 2008. A copy of that letter is attached for your <br />information. The DOW comments were incorporated into our preliminary adequacy review <br />letter in questions number 5, 10, 13, and 14. Colowyo responded on May 27, 2008 and the <br />DRMS second adequacy letter was sent on June 26, 2008. Colowyo responded to that letter on <br />July 28, 2008. We have yet to finalize some of these issues with Colowyo and before we send <br />out another letter, I believe it would be beneficial to meet with DOW to discuss them. The issues <br />we would like to discuss are addressed in our review letter dated June 26, 2008 and Colowyo's <br />responses dated July 24, 2008. Copies of both these letters are attached. A summary of the <br />issues remaining to be resolved is listed below. <br />No. 5. addresses the woody plant density standard. Initially we recommended the standards in <br />DOW's April 14 letter. Colowyo responded with a counter proposal which we did not accept <br />and offered the following comment. <br />Pending discussion with DOW, the Division would accept, as our final offer: <br />• A minimum 450 acres of Sagebrush Steppe (core areas and ecotone, based on 50% <br />success on the 900 (approximate) acres of potential Sagebrush Steppe areas indicated on <br />Map 44. A minimum standard of 375 stems per acre on core areas, 200 per acre on <br />ecotone (no allowance for "positive recruitment"). At least '/2 of the shrubs on core areas <br />and ecotone areas will be big sagebrush (Artemisia tridentata), and none of the countable <br />shrubs will be fourwing saltbush. <br />• Sagebrush Steppe core areas shall comprise at least 225 acres of the post-2008 reclaimed <br />landscape. <br />• A standard of 0 stems per acre on grazingland areas. <br />• A standard of at least 150 stems per acre on at least 3% of the pre-2008 reclaimed <br />surface. <br />Colowyo did not accept this standard in their July 28, 2008 letter and countered with the <br />following proposals: <br />• 375 acres as sagebrush steppe (42% of the area or 75% of what the Division has <br />requested) <br />• 187.5 stems/acre (no issue with the half sagebrush) in "core" areas <br />• Colowyo is still trying to push the issue of positive recruitment, which would quite <br />possibly (probably) make their standard even lower. Positive recruitment is a <br />"demonstration" that the more mature plants are dropping seeds that are germinating and <br />becoming new plants. This method sets up the real possibility that we could begin to <br />argue what is a mature plant and what is a new plant. <br />• The Division has requested that saltbrush be removed from Colowyo's seed mix and we <br />do not feel it is appropriate to count it towards the shrub standard due to the mortality rate <br />around/closely after ten years (the liability period). Colowyo has countered that they <br />have good success with saltbrush beyond ten years and want to keep it in their seed mix
