The nitrate <br /> loading addresses domestic septic usage for the site acreage only. According to the Hantzsche and <br /> Fennemore equation and approach there is a potential for a buildup of nitrates in the ground water <br /> F1to 1.3 mg/L-N. <br /> 4.0 DISCUSSION OF NITRATE LOADING RESULTS <br /> 4.1 Total Nitrate Impact <br /> According to the Hantzsche and Fennemore equation and approach there is a potential for a <br /> buildup of nitrates in the ground water to 1.3 mg/L-N. This is well below the maximum <br /> contamination limit of 10 mg/L-N for nitrogen in drinking water. <br /> The solid waste and waste water generated by the facility will be land applied to adjacent parcels <br /> F1 -under a permit from the California Regional Water Quality Control Board. The land application will <br /> be at agronomic rates according to the Report of Waste Discharge. We would not expect any build <br /> up of nitrogen in the groundwater from the land application of wastes on the adjacent parcels given <br /> Fthe requirements of the California Regional Water Quality Control Board permitting process. <br /> 4.2 Methods of Mitigation <br /> No mitigation is proposed. <br /> F1 <br /> F1 <br /> 7 <br /> Il <br />
