Water quality in the flooded mine is described in detail in Section 9(b)(iv) of this <br />EPP. However, because flow rates from the mine are extremely low, total mass loading from the <br />underground workings is small. <br />Issues related to the flooded mine workings include water chemistry in the mine, flow rates from the mine, <br />potential interaction with water in Ralston Creek, and potential pathways in low-permeability bedrock. <br />These topics are discussed in Sections 8(e)(ii)and 14(b). <br />• <br />• <br />4109C.090807 Whetstone Associates 6
