o Please provide the anticipated flows that will be directed into the ditch and provide <br />documentation to support that the drainage system can handle the anticipated flows. <br />o The proposed ditch will cross over the realigned road in two locations. Please explain how <br />water will be directed over the road, and how the road will ultimately be maintained for <br />vehicle access due to the proposed ditch crossings. <br />o Please provide a cross section of the west ditch, and state if the ditch will be reclaimed. <br />o The operator proposes to direct the west ditch into the lowest pit elevation. The ditch crosses <br />the mad and makes neazly a 180° tum to the north into the lowest pit elevation at a drop of <br />neazly 60 feet. If this ditch is to act as a clean water diversion, the Division does not <br />understand why it would need to be directed into the pit. As an alternative, the operator <br />should consider constructing a clean water diversion ditch that is directed away from the <br />mining area and intersects a natural drainage channel. <br />24. From the permit application text, it appeazs that each highwall will have a ditch that routes water <br />towards the south and eventually into the lower pit. Please provide addition detail, designs and cross <br />sections for these highwall ditches. <br />25. In the application, the operator includes an approximate time table far mining operations. Please <br />indicate all of the mining phases on the map as described in the permit text. <br />26. The Lilly Mill site claim was added as a 3.17-acre area. However, the operator states in the permit <br />text that only 1 acre will be affected. Please include the 1-acre permit area boundary on Exhibit Ca. <br />27. The operator will need to identify all adjacent landowners within 200 feet of the affected land of the <br />Lilly Mill Site Claim and provide the adjacent property owners notice in accordance with Rule 1.6.2 <br />(1)(g). Please revise the map and text accordingly and provide proof of notice. Certified mail receipt <br />copies are acceptable <br />28. In accordance with Rule 6.4.4(f)(i), please state the thickness of the deposit to be mined. Please also <br />state the amount of overburden and waste that will be generated. <br />29. The operatar did not include a small azea of disturbance located on the east side of the permit azea <br />(and to the west of the Colorado Lime Mining claim). Please explain why this azea disturbed by the <br />operator was not included in the permit azea, The operator will need to either include it in the permit <br />azea (and amend the application in accordance with Rules 1.6.6 and 1.8) or provide a detailed <br />reclamation plan and timetable for the disturbed area. <br />30. The Colorado Lime Claim and the Colorado Mazble Claim appeaz to overlap in two segments. The <br />Daisy (* 18148) and Shamrock (4488) and the Chance (* 18148) and Shamrock (4488). Please clarify <br />as to which entity is the claim holder of these overlapping areas. <br />31. Exhibit Ca depicts a vertical shaft and adit opening within the area to be mined. Please further <br />describe these historic mining features and how will they will be impacted from the active mining <br />operation. Please be aware that re-disturbance of previously disturbed areas by the proposed mining <br />operation must be included in the permit area and addressed in Exhibit D- Reclamation Plan. <br />32. Please list and locate on the applicable exhibit all structures that will be constructed on site (i.e. <br />plants, offices, trailers, tanks, etc...) and provide their associated dimensions and composition in <br />order to accurately estimate a cost for removal in the reclamation bond estimate. <br />
