July 29, 2005 <br /> NOA Project Number: E05087A <br /> Page 3 <br /> monitoring of waste water a trucking facility would be the best method for determining Mw. <br /> Normally,when Nc exceeds 10 mg/L-N,we would recommend using an engineered septic system <br /> which is optimized to reduce nitrates,Biologic oxygen demand (BOD), and total suspended solids <br /> (TSS) of waste water. The goal for using an engineered septic system as described should be to <br /> drop the Nc value to below 10 mg/L-N. This is the level which EHD has typically approved <br /> commercial projects with potential nitrate impacts to ground water. <br /> If you have any questions or comments,please contact me to discuss further. <br /> Best Regards, <br /> NEIL O.ANDERSON&ASSOCIATES, INC. <br /> i <br /> D GEO� <br /> 1 !N O <br /> avid J.
