6.4.6 EXHIBIT F - Reclamation Plan Mau <br />13.) In accordance with Rule 6.4.6 the map must show the proposed topography of the <br />area with contour lines of sufficient detail to portray the direction and rate of slope of all <br />reclaimed lands. Please include this information on the reclamation plan map. <br />6.4.7 EXHIBIT G - Water Information <br />14.) The Division could not locate a map that showed the location of the 14 ground water <br />monitoring wells. Please submit a map with the location of these monitoring wells <br />clearly displayed. <br />15.) On page 3 of the Groundwater Modeling and Mitigation Plan (Attachment G-1), it <br />states the existing groundwater level measurements were provided from the 14 <br />monitoring wells. This information was not submitted, please submit this information. <br />16.) On Page 3 of the Groundwater Modeling and Mitigation Plan (Attachment G-1), it <br />states that monitoring will be conducted on a monthly to bi-monthly basis until a quasi <br />steady state is reached and then on a quarterly basis thereafter. Please commit to taking <br />monthly measurements and submitting them in the Annual Reclamation Report submitted <br />by the operator. Once Lafarge believes a steady state condition is reached, they will need <br />to submit a Technical Revision to the Division and receive Division approval prior to <br />changing the monitoring schedule from monthly, to bi-monthly and then to quarterly. <br />17.) Please explain what will occur if the two foot drawdown trigger point is observed. <br />The mitigation plan submitted accounts for what will occur if Lafarge receives a <br />complaint but does not address what will occur if the two foot trigger point is reached. <br />18.) If Lafarge receives a complaint from a water user, they will need to notify the <br />Division immediately, not within two weeks. This notice should include a copy of the <br />complaint (if written), a narrative describing how the situation is being evaluated and <br />what temporary mitigation measure they have implemented. <br />19.) On page 4 of the Groundwater Modeling and Mitigation Plan (Attachment G-1), it <br />states "Lafarge has no responsibility to provide mitigation for wells that are constructed <br />after the permit is approved." This is not correct, in accordance with Rule 3.1.6 (1) the <br />operator is required to minimize disturbances to the prevailing hydrologic balance of the <br />affected land and of the surrounding area and to the quantity or quality of water in surface <br />and groundwater systems both during and after mining operations and during <br />reclamation. Given this, if the mining and reclamation operation impacts the ability of <br />surrounding land owners to legally use groundwater, Lafarge will be responsible for <br />mitigating these disturbances. Please remove this statement from the Groundwater <br />Modeling and Mitigation Plan (Attachment G-1) and submit a new copy. <br />4
