The 18 May 1999 and 11 June 1999 inspection reports pertaining to the North Thompson Creek
Mines have been mailed to you. Some of the items on the I 1 June 1999 inspection report first
appeared on the l9 April 1999, and some others on the 18 May 1999 inspection report. Please
advise the Division of Minerals and Geology (Division) with a description and schedule of your
proposed corrective actions. Again, I apologize for the mix up in dates that aborted our planned
meeting in May.
The purpose of [his letter is to answer a couple of questions you presented during our telephone
conversation subsequent to the 18 May 1999 inspection.
With regard to the repair of the bridges, the bridges are currently classified as segments of access
roads (Permit, Drawings D-2-5 and D-100). All roads are considered for purposes of travel by
land vehicles [Rule l .04(1 l 1)]. The maintenance of access roads is addressed at Rule
4.03.2(6)(a). Thus the decking of the bridges need to be repaired to a condition that will
accommodate light land vehicles such as pick-up trucks, e[c. However, you may need to repair the
bridges to a higher capacity to support the equipment you intend to use to further reclaim the
Portal 1 and fan shafr azeas, and the fan shafr road if appropriate (retention of the fan shaft road
was a subject of the North Thompson Creek/Phase II Bond Release Findings of November 26,
1993, page 5).
The clean up of the cleanings from the long pond is addressed by Rules 2.0~.3(4)(a)(ii)(C),
2.07.7(2) and 4.11.4.
The road downhill of the loadout (hay storage site) that crosses the field to [he Roaring Fork River
might not need further reclamation if it is suitable for the approved post-mining land use [Rule
4.03.2(7)] and is a feature that [he landowner wishes to retain (see Permit, page 4-90). The
Division would need a letter from the landowner to that effect [Rules 2.05.~(2)(a)(iii),
2.05.~(2)(b), and 4.03.2(1)(g)].

Rule 4.02.3 addresses the requirement for perimeter markers about all areas affected by surface
operations or facilities. The markers need to be durable, of uniform design, and easily seen [Rules
