November 23, 2004 <br /> NOA Project Number: E040140A <br /> 4.0 DISCUSSION OF NITRATE LOADING RESULTS <br /> 4.1 Total Nitrate Impact <br /> ` Based on the method and assumptions described, the result of the nitrate loading balance indicates <br /> that the proposed development on the Site will not cause a build up of nitrate in the shallow ground <br /> water aquifer above 10 mg/L-N. The calculated impact is 1.5 mg/L-N. This low result is primarily <br /> ` due to the large size of the property, the relative low septic uses,and the deep percolation of rainfall <br /> for the Lodi area. <br /> ` 4.2 Methods of Mitigation <br /> No mitigation for nitrate reduction is proposed. <br /> 5.0 CONCLUSIONS AND RECOMMENDATIONS <br /> ` Our office concludes that the Site is suitable for proposed development. The calculated impact to <br /> ground water from nitrate generated at the site is minimal. We would recommend that a filter bed <br /> type septic system be utilized for any future growth due to the rapid percolation rate. <br /> 5.1 Signatures <br /> ` The signatures of the environmental professionals involved in the preparation of this report can be <br /> found on the cover sheet at the front of this package. <br /> 5.2 Attachments <br /> All required attachments and appendices can be found at the rear of this package. <br /> 6.0 LIMITATIONS <br /> Our professional services were performed, our findings obtained, and our conclusions proposed in <br /> accordance with generally accepted engineering principles and practices.
