This addendum was prepared in response to a copy of a letter <br /> we received on October 7,2005 from the San Joaquin County Environmental Health Department <br /> (EHD) and a call/visit from Mr. Marc Garcia of Classic Design Construction. Our Soil Suitability <br /> and Nitrate Loading Report was dated June 14,2005. The EHD report review letter was dated <br /> August 9, 2005 —our office had not received a copy of it from EHD. <br /> !/According to the letter,the EHD had reviewed the letter and is requiring an addendum to the <br /> nitrate loading calculations. Essentially,EHD has determined that the amount of truck drivers <br /> should be increased from 5 to 20 drivers. In addition, they have determined that the concentration <br /> of the effluent used in the calculation should be increased from 45 to 85 mg/L-N for the office staff <br /> and truck drivers. The number of residential occupants of the property as een reduced from 7 to <br /> 4 persons. No second dwelling unit is planned for this project and therefore was not considered for <br /> this addendum letter. <br /> The following presents a nitrate loading scenario with aforementioned variables. <br /> LODI ■ SACRAMENTO ■ MODESTO ■ RENO <br /> ENVIRONMENTAL DIVISION 902 Industrial Way,Lodi,California 95240 ■209.367.3701 0 209.369.4228 fax ■www.noanderson.com <br />
