-18- <br />On page 4,05-8 of the application, it is stated that "no gravity discharge of water <br />from the mining operation is anticipated." The basis for this assumption is that <br />all existing C seam mine workings are dry in the Bear No. 1 and No. 2 mines and in <br />the old Edwards mine. However, there is the potential that during mining operations, <br />localized perched aquifers will be encountered. <br />Rule 4.05.10 requires that surface entries and accesses to underground workings be <br />designed to prevent or control gravity discharge of water from the mine. The <br />application states that, "if ground water is encountered, it will be routed to an <br />underground sump". However, no design is provided for this sump, and no plan is <br />presented for handling and treating mine discharges. The workings of the proposed <br />Bear No. 3 dip towards the portals. Therefore, any mine inflows would drain toward <br />the portals, and if not controlled, these inflows may discharge to the surface and <br />impact surface water quality. Therefore, the following stipulation is necessary: <br />STIPULATION NO. 3 <br />WITHIN ONE MONTH OF PERMIT ISSUANCE, THE PERMITTEE WILL SUBMIT TO THE DIVISION R <br />DETAILED PLAN FOR HANDLING AND TREATING ANY DISCHARGE OF WATER FROM THE UNDERGROUND <br />WORKINGS WHICH DOES NOT MEET THE EFFLUENT LIMITATIONS OF 4.05.2. THE PLAN <br />WILL ADDRESS THE MEASURES TO BE USED TO PREVENT OR CONTROL GRAVITY DISCHARGE <br />INCLUDING CONVEYANCE TO, MAINTENANCE OF, AND DISCHARGE FROM SUMPS, SEDI- <br />MENTATION PONDS OR A TREATMENT FACILITY ON THE PERMIT AREA. <br />With the acceptance of the above stipulation, a1Z surface water concerns raised during <br />the permit review have been satisfactorily resolved and the proposed operation will <br />be in compliance. <br />
