WATER RESOURCES <br /> Exhibit G <br /> Water Resources <br /> General Overview: This operation exists on the top of a mountain and therefore water resources are <br /> extremely limited. No groundwater is known to exist within the material to be mined (the quartzite) <br /> so no effects on groundwater will occur. Groundwater does exist in very limited amounts in <br /> formations underneath the quartzite, but because the bottom of the quartzite will not be penetrated <br /> no effects on those groundwater resources will occur. Therefore, the only effects on water resources <br /> will be on the very limited amount of surface runoff that occurs after rainstorms and as a result of <br /> snowmelt. <br /> Surface Runoff: Within the area of Phase 1, a few small drainages are found, but these are highly <br /> ephemeral and only contain water after major precipitation events. At the end of the operation the <br /> drainage from within the mined area will be reconnected to these drainages. Therefore, no <br /> significant effect on volumes will occur. During the operation, sediment will not enter these <br /> drainages because the mining itself will form a barrier to any water leaving the site. <br /> Although Phase 2 has not been planned, drainage effects there will be even less than that <br /> present in Phase 1. Phase 2 is truly on the top of the mountain and therefore there is little watershed <br /> available to establish any drainages. In all probability the mining of Phase 2 will be designed to <br /> operate much as it does in Phase 1, that is, a mine created barrier will be maintained to prevent <br /> sediment from leaving the site. Also, the reclamation of Phase 2 will also reconnect what few <br /> drainages are present so at the conclusion of the operation water volumes derived from the area will <br /> be similar to historical levels. <br /> Project Water Requirements: Water requirements for the operation will be minimal. No washing <br /> will be done on site. Any washing of product, if that is needed at all, will be done at other locations <br /> in Colorado Springs. Therefore, the water required for the operation will be only for dust control. <br /> The actual quantity of water cannot be determined because dust control is weather dependent as well <br /> as dependent on other methods used to reduce or control dust. <br /> In the previous operator's plan, the spring located southeast of the site was expected to be <br /> used as a water source. It is not known whether this spring was used, but features present in the <br /> vicinity of the spring seem to indicate this was at least attempted. This spring does not connect with <br /> any downstream sources. <br /> Original estimates indicated the spring produces as much as 25 gpm, but recent inspections of <br /> the spring indicate that volume is probably not consistently achieved and probably only during very <br /> wet years. It is more likely that this spring usually produces about 3 to 7 gpm which is not sufficient <br /> to supply much water for dust control. Furthermore, the water from this spring supports a small, but <br /> rich wetland dominated by cattails, rushes, and other wetland plants. Although it is an isolated <br /> wetland of small extent and probably of little functional value, removing the amount of water needed <br /> for the project from the spring that supports the wetland would probably result in the destruction of <br /> the wetland. It therefore appears at this time that utilization of the spring as a water source for this <br /> project is associated with too many wetland problems and probably is of insufficient volume to <br /> supply the needs. Further investigation of this source may show that development of the water is <br /> feasible, but at this time the spring is not considered a probable source of water. <br /> Table Mountain Quarry - Castle Concrete Company Exhibit G Page G-1 <br />
