Ms.Lisa Medina January 26,2004 Page 3 Responses, Nitrate Loading Study Check list: 3.5/3.6 Please refer to the revised nitrate loading calculation attached (Tables 3 and 4). 4.1/4.2 The revised nitrate loading calculation indicates an Nc number of 7.2 mg/L-N. This number is below 10 mg/L-N and no mitigation is proposed at this time. It is estimated that any further expansion of the facility will require a revised nitrate loading estimate which will most likely require treatment to reduce total nitrogen of the waste water. Additional Recommendations We recommend that the waste water be metered and reported during the water quality testing of the well water. At a minimum, a water flow meter should be installed at the well head and another meter be installed at the landscape irrigation flow pipe as a minimum. The difference would be waste water and coffee product use. In addition, some thought and careful planning should be made to optimize the site with respect to future development beyond the scope of this Use Permit. Setting aside other areas that could be used for waste water disposal would be prudent. Our professional services were performed, our findings obtained, and our conclusions proposed in accordance with generally accepted engineering principles and practices.
