Woodbridge Rd. <br /> Acampo, CA 95220 <br /> Regarding: Addendum to Soil Suitability/Nitrate Loading Study (SR0047125) <br /> Heritage Oak Winery <br /> 10112 E. Woodbridge Rd., Acampo, CA <br /> PA-0600033 (SA), 500009308 <br /> Original report prepared by Neil O. Anderson & Associates, Inc. <br /> Report dated June 12, 2006 <br /> Mr. Hoffman: <br /> To address the requirements of the San Joaquin County Environmental Health Department in its <br /> letters dated August 27, 2012 and September 6, 2012, we have prepared an addendum to the <br /> above report prepared by Neil O. Anderson & Associates (NOA) in 2006. We understand that <br /> you plan to host additional special events and accommodate more guests at each winery event <br /> than originally accounted for in the Soil Suitability/Nitrate Loading Study (SSNLS). The aim of <br /> this addendum is to incorporate these new use numbers into the nitrate loading calculation. <br /> We are the original authors of the NOA report, and we have utilized the same nitrate loading <br /> calculation as in the NOA report for this addendum. It should be noted that, since the time of <br /> the original report, the winery has been split from its original 106-acre property and now <br /> occupies a 10-acre parcel. We have also updated the value for the deep percolation of rain to <br /> be consistent with the data we utilize in our current reports. <br /> To assist the reader in following the calculation, we will present a new Nitrate Loading <br /> Calculation in its entirety. <br /> NITRATE LOADING CALCULATION AND DISCUSSION <br /> Because of concerns of nitrate leaching into ground water from septic systems, a nitrate loading <br /> analysis was required by the San Joaquin County Environmental Health Department for <br /> approval of the proposed development. The study estimates the potential concentration of <br /> percolating effluent produced by the proposed project over the long term. Where percolating <br /> effluent leaches into the ground, ground water quality may be impacted to some degree should <br /> the effluent reach ground water. <br /> Environmental •.
