Berrien - 2.05.6 <br />The following summarizes the frequency of ongoing operational monitoring, as approved by DNIG; <br />• Springs and Seeps -Discharge measurements and field water quality parameters axe <br />collected twice during the period June through October If sites axe accessible. <br />• Stream Stations -Flow and field water quality parameters are measured on a monthly <br />basis from April through October if sites are accessible. Water samples are collected (if <br />flowing) for laboratory analysis once during the 2^d and 3~ quarters. The exceptiean is <br />monitoring for the North Foxk stations (NF-land 3), which continues on ayear-round <br />basis, including collection of water samples during 4~h quarter. <br />BC-2 and BC-3 sites are only monitored for flow and field parameters twice during June <br />after tributary flow has ended. <br />• Monitoring Wells -Ground water ievei measurements, Held water quality pazametexs, <br />and laboratory samples were taken following well installation and development and water <br />levels and field parameters are measured twice during the period June through October if <br />sites are accessible. If ground water is present, a sample is collected for laboratory <br />analysis during 3~ quarter. <br />The water quality monitoring parameters list is presented in Table 2.04.7-T1, Surface and Ground <br />Water Monitoring Parameters. All water monitoring analysis results will be recorded, reviewed to <br />identify potential problems or trends, and filed at the mine so as to be available for future inspection <br />and review. In addition at the end of each water year, OMLLC will tabulate all water moniroring data <br />for the year, review the data with respect to changes in surface and groundwater hydrology systems, <br />and provide a summary Annual Hydrology Report by Apx$ 30a' for the preceding water to the DP,4G, <br />OMLLC will continue to collect and evaluate hydrologic monitoring data consistent with the <br />Hydrologic Monitoring Plan during the operations and reclamation phases. If the additional data <br />resulting from ongoing hydrologic monitoring indicates that any significant changes in general <br />baseline characterizations axe appropriate or that any assumptions or projections used to evaluate <br />potential hydrologic impacts are inaccurate, they will be reviewed with consideration of all availgble <br />data. If the analysis of any surface water ox ground water sample indicates noncomphance nth <br />applicable permit conditions, then OMLLC shall promptly notify the DMG and immediately <br />implement accelerated or expanded monitoring to determine the nature and extent of noncomphance <br />ai;ua; ~'e~l`; a~auZn^a;;k-il~as;r.^ <br />OMLLC will continue surface and ground water monitoring activities after completion of redama4on <br />operations to document restoration of pre-mining hydrologic characteristics. All surface ynd <br />groundwater monitoring installations and associated structures and equipment will be properly <br />installed, maintained, and operated to assure the accuracy and consistency of monitoring data. <br />Surface water monitoring will be discontinued when untreated surface mnoff meets applicable <br />effluent limitations and the DMG approves removal of drainage and sediment control structures. <br />Groundwater monitoring wells will be abandoned and removed in accordance with applicable DNIG <br />guidelines and permit commitments following DMG approval to discontinue groundwater <br />monitoring. <br />Protection of Public Parks and Historic Places <br />;;hge s,~ .;u^ t'u~51i: rs:ks ~ ~sk..steu ~~stZ.i^ rriati es s: a: e~ cl:se rACr•:: 4~, ., a?w. ~i:ti 1rt;:. <br />area so this regulatory section is not applicable. <br />TR45 2.05-101 Revised February 2004 <br />
