PERMIT #: M- 1982 -131 <br />INSPECTOR'S INITIALS: PSH <br />INSPECTION DATE: June 6, 2012 <br />Operator. The slopes appeared to be the approved 3H:1V and native grasses had volunteered on the slope. <br />As cited above as a problem, the current mine plan needs to be updated and clarified pursuant to C.R.S. 34- <br />32.5 -112 (1)(c)(VI). The Operator must provide sufficient information to describe or identify how the Operator <br />intends to conduct the operation. The Operator shall submit a Technical Revision, with the required $216 <br />revision fee, to update and clarify the current approved mine plan to reflect existing and proposed activities by <br />the corrective action date. The technical revision, at minimum, should address the requirements of Rule 6.4.4 <br />— Mining Plan, Rule 6.4.12 — Reclamation Costs, Rule 6.4.19 — Permanent Man -Made Structures and 6.5 <br />Geotechnical Stability Exhibit, if structure agreements for the potentially affected structures cannot be <br />obtained. <br />Financial Warranty: <br />The Division currently holds a financial warranty in the amount of $68,984.25. The financial warranty appears <br />to be inadequate to reclaim the site based on the slope backfilling now required and the possible removal of <br />the imported material. The Division will recalculate the required financial warranty based on the technical <br />revision information required as the corrective action and the determination of the Mined Land Reclamation <br />Board if a violation has occurred at the site. <br />Hydrologic Balance: <br />The site is currently covered by a Substitute Water Supply Plan and the Operator complied with the Division's <br />exposed ground water mitigation letter dated April 30, 2010 by decreeing five shares of Greeley Irrigation <br />Company water rights. <br />Revegetation: <br />Canada thistle, a List B noxious weed by the Colorado Weed Management Association, was observed on the <br />reclaimed eastern shoreline of Area A. The Operator will need to implement the approved weed control plan <br />to control the spread of the weed. If a weed control plan is not already in place, the Operator shall develop a <br />weed control and management plan in accordance with Section 3.1.10 (6) of the Rule. This plan should be <br />developed in consultation with the county extension agency, or weed control district office and should include <br />specific control measures to be applied, a schedule for when control measures will be applied and a post- <br />treatment monitoring plan. This weed control plan shall be submitted to the Division as a Technical Revision <br />to the approved plan with the appropriate Technical Revision fee of $216.00 if needed. <br />Page 3 of 6 <br />
