This letter constitutes an addendum to the <br /> suhiect report. On page 13, Section 8.1, conclusion number 4 is modified to read as follows: <br /> 4. Given the limitations of=the Hantzsche and Fi nnemore model, it is likely, <br /> although unproven, that nitrates under actual conditions will not exceed <br /> the MCL limit. Nevertheless, the model yields the result that nitrate <br /> f exceeds the MCL limit, and it is possible that the San Joaquin County <br /> EHD may impose additional design requirements on the new septic <br /> f <br /> system to help reduce nitrate loading beyond the levels expected with a <br /> { standard-septic-system <br /> If you have any questions, please do not hesitate to call (209) 569-0293. <br /> E - <br /> Respectfully Submitted, <br /> Gen-Phase Enviro ental Inc. <br /> Stephen M.
