t t <br /> Soil Suitability and Nitrate Loading Evaluation-Update-2 Page 3 of 18 <br /> Great Pacific Nut—Nut Processing Facility Expansion <br /> 3501 Lehman Road, Tracy, California <br /> September 6,2019 CTE Job#25-0710G <br /> described above was originally identified as "P-1" in the first report, but, has been <br /> identified as "P-1X" in subsequent reports (including the attached report) and "P- <br /> 1"was reassigned to the second test performed on July 19, 2019. As a result, and <br /> indicated herein, the attached report should be considered to supersede the <br /> previous report(s). Based on the failing test,the proposed leach field location was <br /> shifted to the east and an additional test (identified as "P-1" in this report) was <br /> performed within that area. Information from test "P-1X" was not used in the <br /> calculations since it was a failing test located within the old proposed leach field <br /> area. Percolation tests herein are accurately located and identified. <br /> Regarding the SJCEHD comment indicating a permit was not obtained for the geological <br /> (groundwater)boring. <br /> • Please note that an "Onsite Wastewater Treatment System Permit"was issued <br /> for to perform the percolation testing by SJCEHD on 4/4/19 and is included <br /> within the report in Appendix B. CTE (apparently incorrectly) assumed that <br /> the groundwater boring would be included with the percolation testing since <br /> the county requires a 10 ft separation between high groundwater and the <br /> bottom of the leach field. Please accept our apology for this <br /> misunderstanding. In the future we will be sure to obtain a separate permit for <br /> any additional groundwater borings. <br /> • In a telephone call with SJCEHD, on July 26, 2019, regarding permitting for <br /> percolation tests, it was conveyed that a permit is not necessary for <br /> percolation tests to be used for design of stormwater drainage systems, but, is <br /> required for percolation tests used in design of septic systems. If this <br /> information is inaccurate please notify our office. <br /> Regarding the SJCEHD comment to provide clarifying information on the dates installed, <br /> purpose,the depths and actual locations of all borings and OWTS percolation test holes. <br /> • Requested information is included within the attached report, purpose of test <br /> holes P-1 and P-IX was to perform percolation testing; dates, locations and <br /> depths herein are accurate in the report and information provided in the <br /> attached report should be considered to supersede any previous reports or <br /> other previous information provided by this office. <br /> Regarding the SJCEHD comment that clarification or corrections should be made to <br /> inconsistencies in our nitrate loading estimate. <br /> • Corrections have been made to the attached report. <br /> Please note that we are in the process of obtaining a sample of well water from the site <br /> for background Nitrate testing. <br /> SACRAMENTO • FREMONT • MODESTO <br /> INSPECTION&TESTING•GEOTECHNICAL•ENVIRONMENTAL-CONSTRUCTION ENGINEERING <br />
