Operations and Maintenance: <br /> • The monthly MPCA Discharge Monitoring Report was completed and submitted as <br /> required. <br /> • On the 2°d, samples from the secondary pond were collected and sent off for results. <br /> `-- Began discharging on the 17th and will do so until the level will be low enough to make <br /> repairs on the air leaks. After making a small repair on the south irrigator, all are <br /> working fine. <br /> • On the 12th,responded to a power outage at 11:15 p.m. Power was restored before <br /> having to use generator at the main lift station. All alarms at the water plant were then <br /> acknowledged. <br /> • On the 13th,Herschel Biasing from the M.P.C.A. stopped by due to a couple of odor <br /> complaints he received, due to the aeration problems we've been experiencing at the <br /> treatment plant. I explained that this is set as a priority as soon as we can lower each <br /> pond to attempt to fix the air leaks in both ponds. <br /> • Approximately 80%of the entire sewer mains have been jetted and should soon finish. <br /> Bacterial enzymes and root killer have been placed in several areas to assist in reducing <br /> any problems.No problems have been encountered to date. <br /> • As discussed at last months meeting, we had received several quotes to purchase a new <br /> lawn tractor. After checking with several lawn mowing services, we have decided for <br /> now that our most economical direction is to rent a tractor from AAA rental. Mike has <br /> allowed us to utilize the trailer for transporting the tractor to and from AAA rental. <br /> Costs are broken down on lawn mowing expense sheet. <br /> Report Submitted By: Gary Giltner <br /> Water/Wastewater Supervisor <br /> City of Pequot Lakes <br />
