My comments are listed below and <br />organized by section. If you have any further questions or comments, do not hesitate to ask. <br />2.05.4(2) — Reclamation Plan Elements <br />The text on page 5 -7 states that the post mining land use is industrial, commercial, recreation and <br />residential which is different than the discussion in Section 2.05.5(2) on page 5 -17 stating that the <br />PMLU is dryland pasture. Please correct the description on page 5 -7 so it is consistent with the <br />requested change in PMLU. <br />2.05.4(2)(b) — Reclamation Cost <br />The current reclamation cost estimate approved in RN -4 has five remaining reclamation tasks with an <br />estimated cost of $84,714.36; however, the permit states that there are no known remaining reclamation <br />obligations and that DRMS is required to maintain a minimum bond of $10,000. This paragraph in the <br />permit (page 5 -7) does not reflect the current reclamation cost estimate and implies the remaining state <br />held bond is $10,000. Please amend this paragraph to discuss the remaining reclamation tasks or <br />reference the current reclamation cost estimate. <br />2.05.4(2)(e) — Revegetation <br />1. The first paragraph (page 5 -8) explains that the post mining land use was changed from wildlife habitat <br />and cropland to industrial /commercial, recreation and residential in TR -5 and the revegetation plan was <br />amended in the 1996 -1997 mid -term review. It does not address the change in post mining land use nor <br />the reclamation standard proposed in PR -1. <br />The goal of the currently planted vegetation was to adequately control erosion. It is unclear from the <br />discussion provided if the vegetation currently planted in the reclaimed area will meet the criteria of a <br />dryland pasture and support livestock grazing. Please include a discussion of how the current <br />o� cow <br />1313 Sherman Street, Room 215, Denver, CO 80203 P 303.866.3567 F 303.832.8106 http: / /mining.state.co.us I <br />John W.
