Bender Road <br /> Acampo, CA 95220 <br /> Re: 2nd Addendum- Soil Suitability and Nitrate Loading Study <br /> STAMA WINERY, 17521 DAVIS RD., LODI,CA <br /> (APN 025-160.12) <br /> Dear Mr. Ross: <br /> Reference is made to our Soil Suitability and Nitrate Loading Study dated July 22, 2013 and <br /> an addendum dated November 6, 2013. The addendum was prepared in fulfillment of a <br /> request by the San Joaquin County Environmental Health Department to recalculate the <br /> nitrate loading based on a projected nitrate effluent load for employees of at least 80 mg/L <br /> rather than the 60 mg/L that was used in the original report. Since then, the agency has also <br /> requested that the calculations be revised to reflect waste volume for the caretaker residence <br /> assuming 2 resident per bedroom. In addition the agency asked that the per/resident effluent <br /> volume be normalized to conform with other recent nitrate loading reports. This resulted in <br /> changing the previous 60 gallons per resident per day assumption to 50 gallons. These <br /> change also require that the nitrate load be reconsidered. <br /> The Section headings in the attached addendum correspond with those in the original report. <br /> The changes from the original report and the fust addendum are highlight by a blue font color. <br /> Respectfully submitted, <br /> Geo-Phase Environmental Inc. <br /> Stephen M. Lankford <br /> President <br /> Enclosure <br /> CC: San Joaquin County EHD <br /> 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc. Phone: <br /> (209 569-953 <br /> Modesto,CA 95356 <br />
