EXHIBIT G WATER INFORMATION The major hydrologic feature is the Eagle River. It will not be directly affected by the Gypsum Ranch Sand and Gravel Pit. No part of the proposed gravel pit is in the 100 year floodplain for the Eagle River. Spring Creek is located to the west of this project and Alkali Creek is located to the east of this project. The existing surface flow of s[ormwater is sheetflow from the upper terrace to the lower terrace. During the mining and post-mining stage, the stormwater will sheet flow to channels located in the northern banks. The channels will discharge to the lower terrace. Erosion control measures will be installed along the channels to minimize impacts to the surface water hydrology (per the requirements of the NPDES Permit). Four springs aze located on the lower terrace of this parcel. The owner has 100% interest in the water rights for the springs. This project will not be using or effecting the water in the springs. The owner also has water rights in the Stremme and Gates ditch as follows (provided by Delaney & Balcomb, P.C. on October 30, 1996): "an undivided fifty four and one-half (54.5%) interest of the following described water rights, ditches and ditch rights. The water rights, district priority no., source, and the decreed right of diversion in cubic feet per second are described as follows: PRIORITY OR NAME SOURCE CFS CASE NO. DISTRICT STREMME AND GATES DITCH EAGLE RIVER 0.8 142 37 STREMME AND GATES DITCH EAGLE RIVER 0.17 160 37 STREMME AND GATES DITCH EAGLE RIVER 8.0 206 37 STREMME AND GATES DITCH EAGLE RIVER 0.6 381 37 STREMME AND GATES DTI'CH EAGLE RIVER 5.25 407 37." The Stremme and Gates ditch diverts water from the Eagle River approximately 1 1/4 miles east of the eastern property boundary of the ranch. The water from [his ditch is what will be used to operate the washer plant. The existing water quality will be maintained by using silt fences along the outside edges of the proposed channels. Staked hay bales will be used in the channels near the discharge points. Settling ponds will be used for the washer and crusher operations. This will remove the finer particles prior to releasing to the outfall channels. The owner has applied for a National Pollutant Discharge Elimination System (NPDES) permit.
