OF MINERALS <br />_ 8 GEOLOGY <br />Please find enclosedche above referenced discharge monitoring report for the period front April 1, 1993 through <br />June 30, 1998. No permit limitation exceedences occurred during the quarter. <br />Outfall 002 was tested for fecal coliform once a month as required. On 4/1/95, the laboratory concluded that <br />the sa- mple could not provide a tangible count because these organisms were 'Too Numerous To Count'. Obviously, <br />this result was not figured into the DMR statistics, but it is noted as being accomplished within the 'Frequency of Analysis's <br />column. A letter of brief explanation from the participating laboratory is included with this submittal. <br />Presently the laboratory is trying to establish more concrete results to determine if TCC was within the required <br />limits or actually incuued an exceedence. In addi[ion, TCC and ACZ laboratories are trying to institute alcernative <br />res[ing methods for furore samples, so this problem does not arise again. <br />Additional information and methods will be forn~arded to your department as soon :u possible. <br />There is no discharge at Outfall 001 to enable chemical or toxicological testing to dace. <br />Please contact me at (970) 879-3800, ext. '_805 for any further questions or additional information. <br />COMPANY <br />S. Carter <br />ental Specialist <br />enclosures <br />cc: DMG <br />CWPS Permit No. CO-0042161 file <br />
