Submitted by: J. Mersch Ward July 13, 2003 Earthmovine Operations ¶ 1: Notes that soil stockpiles only to be seeded if left in place more than one yeaz. It is suggested that any soil depositories that cannot be seeded and insure growth during the concurrent season following seeding and any pile to be left unseeded for period up to a year be covered with an appropriate material, to insure minimal loss from wind and water erosion. ¶ 2: All soils and overburden need to be retained on site for pit back fill to insure a reduced final depth and to re-establish current soil profiles. Reference has been made further into the report that excess overburden and soils would be sold and transported off site. In maintaining a good reclamation program there is no such thing as excess soils, thus all material should remain on site. Water Diversions and impoundments Run off water, makeup water and recirculated process water needs to be retained in lined settling ponds to avoid ground water contamination. Runoff water from the plant site will likely contain hydrocazbons from asphalt operation, fuelling spills and from general equipment maintenance. Dischazged water onto the surface or into an aquifer should meet drinking water standards to avoid down stream contamination. ¶ 2: 658 acre-feet of water per yeaz are noted to be under contract from the Uncompahgre Valley Water Users' Association. Currently water delivery from the CJ Lateral ditch is limited to April through mid-October. It is not clear how water will arrive on site during the period of November through Mazch. Nor is it cleaz as to the availability of water during period of drought and restrict delivery. Will storage ponds be required or are there expected periods of forced shutdown? This needs to be clarified should extra stomge facilities be required. Operation Timetable Table 1-Operations timetable: the preceding paragraph notes a 21yeaz operating life followed by a 2-year reclamation period. However, Table 1 notes a five phased mining cycle totaling 25 years, which is followed by a 2-yeaz reclamation period. It appears that there is more than one mining plan being considered. This needs to be clarified. Phases General; Maps need to be prepared for each mining cycle (Phase) so that it is cleazly understood where the processing facilities aze located in each phase as related to the mining activity and as to the settling ponds. If there are temporary facilities during eazly phases this should also be map located. No reference is made to stockpiles of finished gravel or crude ore for processing. This information is needed to better understand concurrent reclamation. A second set of maps is needed to reflect concurrent and finished reclamation that correlates with the 5 phase mining cycle maps.
