<br />B. Surface Water <br />Surface water information is contained in Sections 2.04.7, 2.05.6 and <br />4.05 of the MRP. Baseline information is included, as well as results <br />and evaluation of surface water monitoring performed during the previous <br />permit term. The surface water monitoring plan is summarized in <br />Exhibit 25 and on pages 2.05.6-51 through 54. The surface water <br />monitoring plan for the Southfield Mine remains unchanged except for the <br />addition of one monitoring station on Second Alkali Creek for measurement <br />of peak flows. <br />A more complete discussion of surface and groundwater within and adjacent <br />to the permit area is contained in Section VIII (Probable Hydrologic <br />Consequences) of this document. <br />The original Findings Document included a stipulation (No, 2) requiring <br />the operator to continue the approved hydrologic monitoring until the <br />Division modified or cancelled the program, Page 4.05-26 of the permit <br />application contains a commitment to do this. Therefore, Stipulation <br />No. 2 is no longer necessary. <br />The operation is in compliance with the requirements of this section. <br />VI, Water Rights and Replacement - Rules 2.04.7 (3 ),2.05.6(3)(ii),2.07.6 <br />.~-ir <br />Information on water rights and replacement is contained in Section 4.05.15. <br />The mine operations have not affected any surface water rights during the <br />initial permit term and no impact is expected as a result of the permit area <br />expansion. The City of Florence's Newlin Creek water line has not been <br />affected by the Southfield Mine. <br />As discussed in Section VIII of this document, the Thompson Well has been <br />rendered inoperable due to damage to the casing as a result of the abandoned <br />Rex Carbon Mine operations. The other two wells in the mine's affected area <br />are still operable. EFCI obtains water for consumptive use at the <br />Southfield Mine from the Corley Mine Well. This well is adjudicated for <br />41.4 ac-ft per year of water. Water consumption at the mine has never <br />exceeded this amount. <br />The original Findings Document included a stipulation (no. 3) requiring the <br />operator to provide doamentation of filings with the State Engineer's Office <br />for storage and consumptive use of water. In response to enforcement action <br />by the Division, EFCI cortonissioned a study of water rights for the mine in <br />February, 1987. In response to adequacy concerns raised during review of <br />Permit Revision No. 1, EFCI solicited a legal opinion on the status of the <br />mine's water rights. After reviewing these documents and permit materials, <br />the State Engineer's Office informed the Division that no additional water <br />rights filings by EFCI were necessary as long as water consumption does not <br />exceed that adjudicated for the Corley Mine Well. Therefore, Stipulation <br />No. 3 is no longer necessary. <br />-9- <br />
