Effluent Fecal Coliform Geometric Mean— colonies/I00 ml <br /> Permit Condition—200 organims/l00 ml <br /> d. Flow- Average Daily Flow— 59,202 gallons (Design—121,795 gal/day) <br /> Maximum Daily Flow—89,562 gallons <br /> Minimum Daily Flow—33,396gallons <br /> Total Monthly Flow— 1,124,838 gallons (as of the 19th) <br /> II. Operations and Maintenance: <br /> • The monthly MPCA Discharge Monitoring Report was completed and submitted as <br /> required. <br /> • The test results from the samples taken from the monitoring test wells were all good. <br /> • The attempted repairs to the pond slide gates were completed on Oct. 31st. To isolate <br /> each pond test balls were placed in each of the ponds utilizing a commercial diver to <br /> install.A six inch pump was rented to assist with pumping water from one pond to the <br /> next to assist in the installation of the test balls so the pit could be isolated for the <br /> repairs. Conclusive findings were: <br /> ➢ Both brackets that support the two slide gates needed repair. One was <br /> needed to be placed back into the concrete which required placing <br /> larger anchors in the wall to support bracket. The other was broken <br /> and needed to be re-welded to repair. <br /> ➢ It appeared that the original concrete wall that is connected with the <br /> secondary pond wasn't poured properly and thus a concrete"shim" <br /> was put in to compensate for the error,part of which was missing. <br /> Grouting material and sealant was used to repair.New anchors were <br /> placed in the bracket to hold it securely to the wall and sealant was <br /> placed around the entire gate bracket. <br /> 2 <br />
