Shadow Lake is not <br /> required to disinfect. <br /> Reporting <br /> Timely reporting all activities required in the Waste Discharge Requirements has been a significant <br /> challenge for Shadow Lake staff in the past. We have changed the flow path of information and <br /> streamlined some of the data handling in order to completely fulfill the requirements of the discharge <br /> monitoring requirements. This has resulted in on-time and accurate reporting of all monitoring parameters. <br /> Calibration Log <br /> Shadow Lake does not use any analytical instruments that require calibration for the reporting of waste <br /> discharge requirements. All analysis is performed by a certified laboratory. Effluent flow meter was <br /> calibrated on March 27, 2013 by Cooper Controls of Acampo, CA. Flow measurement was <br /> within 1% of calibration. <br /> "I certify under penalty of law that I have personally examined and am familiar with the information <br /> submitted in this document and all attachments and that, based on my inquiry of the those individuals <br /> immediately responsible for obtaining the information, I believe that the information is true, accurate, and <br /> complete.
