Long <br />Drvisinn Dirctrar <br />I have reviewed your Hydrology Report, submitted and received <br />August 5, 1993 and find the report to be within the standards <br />outlined in both the permit and in the revised Stipulations 1 and <br />2. <br />There are no problems noted with the biannual monitoring lab <br />reports, although both ammonia and fluoride seem higher than usual, <br />all parameters are within Colorado Department of Health <br />regulations. <br />Continued compliance with water level measurements, EC, temperature <br />and pH are also evident. Daily mine inflows were also presented as <br />requested in Stipulation No.2, as was mine consumption. A mine <br />workings map was also included. <br />In conclusion, I find the report to be complete and satisfactory. <br />Thank you for your timely submittal. <br />Sincerely, <br />t <br />Sh n, 1E.
