-2- <br />Samples are collected from the streams at a point of flow using a <br />peristaltic pump. Typically, four to five liters of sample are col- <br />lected from each location. The appropriate types of sample containers, <br />filters, and preservatives are used. The samples are placed in coolers <br />along with ice and shipped by air freight to the designated laboratory. <br />Conductivity, pH, temperature, and dissolved oxygen are determined in <br />the field. <br />Attachment p4 is a summary of the analytical data for one of Colony's <br />stream sample locations. The location is station X557 which is located <br />at the stream gaging station F1R in the East Middle Fork of Parachute <br />Creek. <br />1 NPDES Compliance <br />Colony monitors all discharges from Sediment Pond N5 in accordance with <br />our NPDES Permit No. CO-0038270. Attachment k5 is a summary of the <br />permit's effluent limitations and monitoring requirements. A Discharge <br />Monitoring Report is submitted quarterly to the Colorado Department of <br />Health. <br />l Groundwater Quality/Groundwater Levels <br />Attachments #6 and 7 are examples of the data which exists for the <br />numerous monitor wells located at Colony. While Colony feels that a <br />thorough understanding of the area's groundwater is important, we feel <br />that additional monitoring is no longer warranted at this time. Prior <br />to processed shale disposal and commercial mine production, there will <br />be enough time to allow for additional monitoring. <br />DMB:bIs <br />
