1 <br /> Musco Olive Products <br /> - 2 - 19 April 2002 <br /> ro <br /> information on the peak processing time of year. The report shall present a plan to address the <br /> additional employee wastewater generation. <br /> • Review of the calculations on the system capacity contained some items that may be errors. For <br /> example, in the maximum capacity of the existing system the soil factor selected was 0.225 which is <br /> applicable for silt and/or sandy clay loam. Descriptions of the soil type presented elsewhere in the <br /> - - <br /> -report describe the soil as-clay loam-or clay-and the clay nature of the soil is partially relieduponto <br /> prevent surface applied wastewater from percolating into the leach line trenches. The correct soil <br /> factor for the site is likely 0.250 which is applicable for clay and/or peat. <br /> • The report states that San Joaquin County Department of Environmental Health designed the septic <br /> system to serve 196 people. NOA preformed a"back calculation"to show that the system can <br /> actually handle the waste from 287 people. Please have San Joaquin County review the back <br /> calculation and provide information as to whether the agency agrees that the existing system is an <br /> appropriate size for the current number of people at the facility. <br /> • Because two septic tanks in series are used for settling the solids in the wastewater,more frequent <br /> septic tank pump outs may be advisable. The report did not describe the frequency the tanks are <br /> pumped and/or inspected. <br /> As submitted the report is incomplete, Musco Olive Products shall address the items listed above and <br /> resubmit the domestic wastewater disposal system report by 30 May 2002. Please note that primary <br /> responsibility for oversight of the domestic wastewater system will remain with the San Joaquin County <br /> Department of Environmental Health. If you have any questions about the comments provided,please <br /> telephone me at (916) 255-3116. <br /> TIMOTHY R.
