The requirement is the equivalent to 1,175 feet of leach line. The proposed <br />permit is for 1,068 feet, using the 80 feet of leach line. <br />6 x 80 = 480 feet of leach line and 12 x 49 = 588 linear feet equivalent of pits. When resubmitting the permit, do not <br />provide ranges for the lengths, the length of the line will have to be specific and the linear equivalent must be equal to <br />or greater than 1,175 feet. A 36" pit is equivalent to 49' of leach line. <br />The permit application indicates three tanks but the site plan shows 2 tanks. Since the permit application indicates three <br />tanks, three tanks would need to be placed. <br />The design of the system has perforated pipe between the two pits at the end of the leach lines, this line has to be solid <br />line. There are other details that are missing. If the contractor is familiar with San Joaquin County Standards then they <br />will know what to do, if they aren't familiar with county standards there may have to be work to redo the leach lines <br />once the inspector verifies the work. <br />The permit indicates the system is an engineered designed/alternative system, meaning that it does not conform to <br />county standards or is mitigating something not possible with a standard system. If the system is to be an engineered <br />designed/alternative system there is an additional review process from EHD to assess the system. A service request form <br />needs to be submitted along with a fee of $304. <br />Looking at the area where the system is proposed, there seems to be a parking lot in the area and just wanted to <br />confirm that the leach lines will not be driven over or be covered by asphalt or concrete. <br />Are there any wells in the area. If so, how far will they be from the proposed septic system? <br />Thank you, <br />Cesar Ruvalcaba <br />San Joaquin County Environmental Health Department <br />Lead Senior Registered Environmental Health Specialist <br />1868 East Hazelton Ave <br />Stockton, CA 95205 <br />W (209) 953-6213 J1 i,�. cruvalcaba@sigov.org <br />SAN ,IOAQUIN <br />
