tJ <br /> September 30, 2007 <br /> NOA Project Number: E07141A <br /> 3.6 Impact of Nitrate Loading Y to Nearby Water Sources <br /> E Based on the method and assumptions described, in addition to the geologic settin o not, <br /> believe the proposed project will cause a build a of nitrate in the ground water a ove 10 m /L-N <br /> p � g <br /> over the long term. <br /> 1 ' <br /> Since the site is relatively flat,we do not foresee percolating effluent affecting any surface water <br /> resources. <br /> t <br /> 4.0 DISCUSSION OF NITRATE LOADING RESULTS <br /> 4.1 Total Nitrate Impact <br /> i <br /> Based on the method and assumptions described,in addition to the geologic setting,we do <br /> believe the proposed project will cause a build up of nitrate in the ground water above �g/L-N <br /> over the long term. <br /> 4.2 Methods of Mitigation <br /> Fi Because of the favorable result of the nitrate loading calculation, no mitigation measures are <br /> warranted for the proposed development. <br /> 5.0 CONCLUSIONS AND RECOMMENDATIONS <br /> Our office concludes that the proposed project will not cause a build up of nitrates above 10 <br /> mg/L-N in the ground water. We recommend the EHD guidelines be followed for the construction <br /> of the septic system—The site is suitable for s�ta�r�Bard septic systems utilizing shallow leach lines or a <br /> filter bed desi Ns��lts_ be allo irr tY�is area by the EHD.
