(FCE) has <br /> prepared this letter to inform you that recently installed flow meter on the influent line to <br /> the wastewater treatment ponds is not operating properly. Apparently, the meter installed <br /> at the plant was not calibrated for intermittent flows and the control panel was damaged. <br /> Therefore, the influent flow measurements have been higher than actual flows. The <br /> problems were defermined after comparing influent and effluent flow values. For <br /> example the flow measurements for April and May 2003 are presented below: <br /> Month Influent Effluent Difference <br /> April 1,215,000 gal 981,700 gal 20% <br /> May 1,145,000 gal 848,400 gal 26% <br /> The meter and control panel are planned to be repaired in the coming week. The repair <br /> will be noted on the monthly monitoring report. Thank you for your attention in this <br /> matter. If you have any questions, please call me at (831) 426-9054 or Alice Gonzales, at <br /> Alpine Meats at(209) 477-2691 ext. 245. <br /> rely, <br /> PEERHAASE, P.E. <br /> Principal Engineer <br /> cc: Alice Gonzales, Stockton <br /> Mike Huggins, Stockton <br />
