corrugated metal pipe dewatering structures. <br />As described in the Division's January 21, 1998 <br />Estimated Reclamation Costs by Anticipated Project, at least <br />three ponds have access roads which will require reclamation. <br />The estimated costs included grading to a configuration <br />similar to the reclaimed haul roads, installing drainage dips <br />and revegetating these roads. Rolled dips will be built every <br />250 feet on these roads: Mine 2 pond road, 3 dips; Mine 1 <br />ponds road, 2 dips; 016 pond road 10 dips; 001 pond road, 6 <br />dips. 001 pond road does not need additional grading. <br />In estimating this cost, the Division assumed that the <br />sediment ponds will not be reclaimed until such time as they <br />are no longer needed to control sediment generated from the <br />mine site. Because this will be several years in the future, <br />and because the haul roads which provide access to the ponds <br />will have already been reclaimed, an estimated cost is <br />included to repair any damage to the haul roads as a result of <br />moving heavy equipment to the pond locations. The components <br />of repairing damage incurred on previously reclaimed roads <br />(Roads A, B, D, E, F, G) involves re- ripping dozer track, <br />repair of damaged dips; purchase and install fertilizer, seed, <br />mulch. <br />There are documents which relate to this estimated cost. <br />The documents will be made available for inspection at a <br />mutually convenient time at the Division's offices in Denver <br />and \or Grand Junction. <br />32. It was MCR's belief that the lamphouse at the <br />Rock Tunnels portals (see attached USGS Quad Sheet Placita, <br />Colo. Segment) was to remain post- reclamation. If this belief <br />is incorrect, please advise us what determination(s) were made <br />and by what person(s) as to reclamation eliminating this <br />lamphouse. Are there documents relating to this <br />determination(s)? If so, please attach a copy of such <br />documents to your responses to these interrogatories or state <br />the circumstances under which these documents may be inspected <br />and /or copied. <br />Response: The Division's records indicate that Mid - <br />Continent Resources submitted Technical Revision 07 on January <br />7, 1987. This technical revision describes the demolition of <br />the Lamphouse, and was approved by the Division. In addition, <br />19 <br />
