Metropolitan Council <br /> Environmental Services <br /> Guideline for SAC Volume Study <br /> - Contact the engineer in charge of your permit before commencing with the <br /> wastewater volume study option. Special conditions, other than those specified in <br /> this guideline, may apply to your facility. <br /> - The wastewater volume study shall consist of a minimum of 30 continuous days of <br /> volume data acquired from the use of incoming water meter(s) and/or from a <br /> wastewater effluent flow measuring device. <br /> - Deduct meters shall also be used when losses to lawn sprinkling, evaporation, product <br /> loss, etc., exist at the facility. If these losses cannot be accounted for by meter, the <br /> permittee shall submit to the MCES engineering calculations estimating these <br /> losses and/or conduct effluent flow measuring from an MCES approved monitoring <br /> site. <br /> - All values used to determine the actual or calculated daily wastewater flow volumes <br /> shall be submitted for each day of the study. Also, indicate the daily activity taking <br /> Place at the facility during the study (e.g. full operation, cooling water clean up). <br /> - Please account for any unusual events, such as a spill, that may have occurred during <br /> the volume study time frame. <br /> The results of this study shall be submitted to the MCES by March 31, 1997. MCES staff <br /> will calculate a SAC equivalent based on an average of the 5 highest daily wastewater flows. <br /> The MCPS reserves the right to conduct additional volume monitoring if deemed necessary. <br />
