Two six-inch pipelines have also been installed from the pumps <br />to the main pipelines within the mine that go to the surface. Because the water is being gathered as close <br />to the source as possible, reducing the mine floor and/or sump contact where additional sediments can be <br />introduced, MCC believes that the water will be within TSS limitations and would like to dischazge it <br />directly to the spillway of pond MB-l. When dischazging into the spillway directly from the mine, <br />MCC will sample the discharge at the pipe outlet in the spillway independently from other pond MB-1 <br />discharges. MCC proposes to report these dischazges together with pond MB-1 dischazges, unless <br />otherwise directed by the Water Quality Control Division. MCC will sample the water from behind the <br />seals to ensure that TSS limitations can be met prior to initiating dischazges into the spillway. <br />Please contact me should you have questions or require additional information. <br />Sincerely, <br /> <br />Kathleen G.
