iviua ~reex rrt -reclamation Permit Application -112 (C) Exhibits Page 27 of 67 EXHIBIT G -Water Information SUMMARY: This operation is expected to neither directly nor indirectly affect surface and ground water systems. Some irrigated land will be taken out of production, temporarily, during mining, but will be restored to irrigated cropland or pasture within two years; separate request will be made to use some irrigation water for dust control, washing of aggregate, and related uses during mining, primarily by using water that would not be needed for irrigation during the active mining of an area of up to five acres. The mining and reclamation as planned has no reasonable potential to adversely impact on surface or groundwater quality or quantity. Reclamation may leave small basins for infiltration and evaporation of runoff. 1. Sources of Ground Water on site or potentially affected by operations on site: None. There are no wells on the site. The following recorded wells are located within % mile of this site.tl Mining at this site will be limited to depths of approximately 30 feet below existing ground level, or approximately 6770. This places all mining above the known water table,t2 and well above the level of Mud Creek.

Sources of Surface Water on site or potentially affected by operations on site: • The only source of surface water on the site are existing feeder ditches of the various irrigation ditches, and return flow from irrigated land and ponds to the east. • Although the USGS map shows two ephemeral ponds or basins located on the site, the one shown in the southern portion of the site appears to have been filled in by previous owners and no longer exists. It was most likely a pond created to hold return irrigation flows from the irrigated portion of the site. Since this no longer exists, there is no potential for it to be affected by operations on site. The second ephemeral pond shown on the USGS map is located in the extreme northeast corner of the site and appears to have been a dugout used to obtain water flowing underground in the swale. This water appears to be leakage from the series of three ponds located off the site, and return flows from irrigation water. It appears that this swale (which was dry in 2007) was dug to provide additional water for grazing livestock during periods when the low water level in the ponds made it difficult for animals to get to the ponds. It has silted in and serves more as a storm water runoff control basin than a dugout at present. Since this is located within the buffer area (see Mining Plan, Exhibit D) and the ponds themselves are not located in the affected area, there is no potential significant impact on this pond or basin beyond that caused by existing non-mining activities on site. The East Fork of Mud Creek, flowing southwest and south to the northwest and west of the site, is one of the five major tributaries of the Mancos River, and the upper creek (above the confluence with the West Fork) has a drainage basin of approximately 15 square miles (9600 acres). The Creek is located 1000 feet or more from the proposed affected lands, and sixty feet or more below the original elevation of the proposed affected lands. Prior to mining and reclamation, and assuming that mining operations to the west (the Noland Cedar Point Pit) do not block surface flows, approximately'/ the site (80 acres) flows overland and potentially discharges into the creek. Proposed mining and reclamation would remove approximately half of this (40 acres) from normal surface discharge into the Creek, reducing surface drainage area by approximately 0.42%, and therefore not significant. Due to the distance and elevation difference, there is no direct potential effect by mining operations. Reclamation will be important to prevent dissolving salts from the Mancos Shale in exposed areas. ttReview of Colorado State Engineer records, //date//. t2 Based on test holes dug at the site in 2006-7.
