The City of Florence water rights will not be effected by Southfield's <br />mining operations since the Newlin Creek diversion upstream of the mine <br />area diverts all flow from Newlin Creek. <br />The Thompson Ranch Well, which is completed in the Rex Carbon Seam is no <br />longer functional and has not been used for a number of years. The well <br />is connected to a waterline extending from the portals of the abandoned <br />Rex Carbon Mine. Originally, the well provided water to the Thompson <br />Ranch, however the waterline was broken by blasting activities at a nearby <br />surface mining operation. At the time of the initial break, the Rex <br />Carbon Mine had apparently not been abandoned, access to the underground <br />line was still possible, and the line was repaired. However, after <br />closure of the Rex Carbon Mine, the underground line was again broken by <br />either surface blasting activities or caving in the underground workings <br />and could not be accessed for repair. While a water right for ten (10) <br />gallons per minute still exists for the Thompson Well, the well is non- <br />• functional, has not been used for a number of years, and would probably <br />not be affected by Southfield's mining operation, since the Rex Carbon <br />Seam is separated from the interval affected by mining by approximately <br />400 feet of relatively low permeability siltstones and shales. <br />The Corley Mine Well which was completed in the abandoned Corley mine <br />workings in the Rex Carbon Coal Seam is an active well which is utilized <br />as the primary water supply for mining operations. Because of this mine <br />use, EFCI maintains documentation on discharge from the well. This <br />documentation indicates no mining related impacts on flows from the well <br />consistent with the assumption that vertical separation and low <br />permeability of the intervening strata provide effective hydrologic <br />separation and preclude potential mining related impacts. <br />The Corley Company Well, completed in the Raton formation is a marginal <br />well producing only one (1) gallon per minute. The well apparently <br />intercepts a perched groundwater aquifer which should not be effected by <br />. mining due to well location and significant vertical separation. <br />2.05.6-14 <br />
