APPENDIX A <br /> Reference Water Quality <br /> _l Definition of"Reference Water Quality" and the Time Periods of Concern <br /> Reference water quality" is defined as a statistical determination of dissolved <br /> /inc (Ln) concentrations at reference point A-72 for the time penod of lanuarN 5 <br /> 1989 through September 6. 1995 Dunng this time there exist 63 measurements <br /> of dissolved zinc at the reference point which also have either simultaneous <br /> measurements of stream flow or inferred stream flows based on linear regression <br /> analysts of flow data from the Howardsville Station to Station A72. The set of 63 <br /> measurements of coupled flow and dissolved Zn data collected is termed "the <br /> baseline set" representing the available history of dissolved Zn and stream flow at <br /> the reference point This set of data defines reference water quality against which <br /> future water quality will be compared. The reference water-quality data are listed <br /> in Attachment I <br /> f ime following the signing of a Consent Agreement between the State of <br /> Colorado and Sunnyside Gold Company(SGC) shall be divided into two penods <br /> "Project period" is defined to be the time period that begins with the <br /> initiation of mine closure and reclamation activities that are the subject of <br /> the Consent Agreement and ends when (a) A-list projects have been <br /> completed; (b) muie pool equilibrium has been reached; (c) Cement Creek <br /> treatment has ceased; and (d) lower American Tunnel hydrologic controls <br /> and portal plug are complete- <br /> "Post-project period" is defined to be the time period that begins <br /> immediately after the "project peniod" and ends when SGC has been <br /> released from water-quality permits under the terms of the Consent <br /> Agreement. <br /> Classes of Flow <br /> The high-mountain portion of a river such as the Animas is subject to seasonal <br /> fluctuations in flow due to hydrologic response of the basin to climatic factors <br /> Flow and the concentration of dissolved constituents in any river water are <br /> generally inversely related. <br /> "51:4 VILI" 1 a <br />
