The SSNL Study supports the suitability for the OWTS usage with the following conditions: <br /> a. The engineered system,dated September 6, 2019, has been reviewed and accepted. <br /> b. Annual permit is required. Fee for annual operating permit is due at time of OWTS permit <br /> application. <br /> c. To monitor the effectiveness of the engineered system, which is designed to mitigate the <br /> requirement for minimum soil depth from the bottom of the dispersal system to the <br /> groundwater,quarterly sampling of the groundwater for nitrate near dispersal field is required. <br /> The first sampling shall be done six(6)months after the OWTS installation. Sampling results <br /> shall be submitted to EHD for review. The EHD may reduce the sampling frequency after one <br /> year of sampling. <br /> d. Sampling port shall be installed under EHD permit and inspection. <br /> e. The comments and recommendations resulting from the review are attached for your <br /> consideration. <br /> 2. According to EHD records,the existing well was constructed in 2012 for agricultural use and is not a <br /> suitable source for the potable water supply for the new development. A potable water supply that <br /> can provide a consistent source of safe and clean water adequate for human consumption, cooking, <br /> and sanitary purposes for the proposed development project needs to be established prior to the <br /> issuance of building permits(2016 CA Plumbing Code, Section 601.2). <br /> 1868 F.
