In a faxed response, dated January 31, 1994, EFCI informed the <br /> Division of the intent to pursue option one, and that they had <br /> "reopened the file" with the State Engineer' s Office. The Division <br /> was informed on May 23 , 1994 that EFCI wished to pursue the second <br /> option of a closed-loop system in lieu of obtaining a permit for <br /> dewatering. The State Engineer ' s Office concurred with this <br /> decision in a letter dated June 8, 1994 addressed to the Division. <br /> EFCI submitted Technical Revision No. 19, received by the Division <br /> on June 16, 1994 . TR19 outlines the plans to close the North <br /> Dewatering Well and channel the water into old abandoned workings, <br /> and is currently under adequacy review by the Division. <br /> STIPULATION NO. 14 <br /> PEAK FLOW SHALL BE MEASURED IN MAGPIE CREEK ON A QUARTERLY BASIS AT <br /> THE CURRENT MONITORING STATION. DATA ACQUIRED FROM THIS MONITORING <br /> SHALL BE SUBMITTED QUARTERLY AND INCLUDED IN THE ANNUAL HYDROLOGY <br /> REPORTS FOR THE MINE. <br /> Status - On-going <br /> The 1991 AHR indicates that there was no water in Magpie Creek on <br /> six sampling dates in six quarters following the issuance of the <br /> Permit Revision. It is not clear whether flow actually never <br /> existed in the creek during those quarters or that there was no <br /> flow when EFCI did their quarterly monitoring. <br /> During the Mid-term review in 1993 , EFCI was asked to elaborate on <br /> this issue (question No. 13 of the Adequacy Review) , which they did, <br /> with their response received along with a commitment to expend <br /> extra effort at attempting to catch flow during storm events . <br /> Their response explained that since the creek is ephemeral, flow at <br /> the mine sampling site occurs only during storm events, or when <br /> discharge from Pond No.2 is initiated, therefore, unless personnel <br /> are sampling during a storm event, it is likely no surface flow <br /> will be present in the creek channel . Upstream waters are removed <br /> via a pipeline by the town of Florence, so the storm event also <br /> needs to be localized within the mine site area for sampling <br /> purposes . Occasionally, in the months of July and August, large <br /> storm events do occur and the operator has committed to putting <br /> forth extra effort to catch the flow with sampling equipment at <br /> these times . <br /> Because Magpie Creek is an ephemeral drainage, EFCI has been <br /> measuring peak flow after storm events . <br /> Southfield Mine Permit Renewal 03 <br /> 8 <br />
