Intermittent discharges were observed for both <br />Outfalls 001A, and 002A, as a result of snowmelt runoff by the operator. No excursions of effluent limits <br />were reported. However, the pH values measured at outfall 002A are very close to the upper limit at 8.9. pH <br />9.0 is the maximum allowable value. No corrective measures are required at this time. <br />Thank you for your timely submittal of these reports. The reports are in compliance with Rule <br />4.05.13 (2)(a)(iii). <br />Sincerely, <br />Protection Specialist <br />C:/jhb/C92081/Reports/DMRs/2009/2nd quarter.doc <br />CC: John Weinman, Hydro-Environmental Solutions, Inc. <br />P.O.
