I=E~MdT CO-031-81 <br />Date 9-16-83 <br />Ref. Page(s) in permit <br />Ref. Map 7 <br />Stipulation No. 1 <br />FLOW MEASUREMENTS AND WATER SAMPLES MUST BE TAKEN TWICE A <br />YEAR FROM THE THREE SITES IDENTIFIED ON MAP 5 OF THIS <br />DOCUMENT. THE TIMES OF FLOW MEASUREMENT MUST BE ONCE DURING <br />SPRING SNOWMELT AND ONCE DURING A STORM EVENT. THE SAME <br />PARAMETERS FOR ANALYSIS SHOULD BE USED AS WERE USED FROM THE <br />SOAP REPORT. <br />Reply <br />The three sites (001,002,003) indicated on the attached map <br />(Figure 1.1) were. located in the field during an August 22-23 <br />field visit. Cross sections and channel slopes were measured so <br />that a stage discharge curve could be developed to estimate flow <br />values from depth of flow measurements. (Figures 1.2 - 1.4) A <br />bottle sampler was installed at each of the three sites and <br />sample bottles, with preservatives, were issued to the mine <br />operator. <br />A sample from Pond 'K' was taken on 23 August, 1983. No <br />discharge from the pond was occurring, despite afternoon <br />rainshowers on the two previous days. As discussed with Ms. Sue <br />Mowry, the CMLRD representative on the site, the results of the <br />sample will provide some baseline data and would be preferable to <br />no data at all. Runoff events are infrequent at this site and <br />there is no certainty that a flow event would occur prior to the <br />time at which the operators are ready to begin mining. The <br />results of this sample are attached. (Exhibit 1.1). <br />The sample from spring snowmelt has not been obtained. This <br />will be collected in the spring and submitted. <br />
