The proposed development project includes: <br /> 1. A 15,000 square feet agricultural building on 14.0 acres lot. <br /> 2. The OWTS usage wastewater average of 929 gallons a day from existing classroom building <br /> and the proposed 15,000 square foot agricultural building. The OWTS usage wastewater of <br /> 929 gallons a day is not to be used to septic design or size calculation. <br /> Based on the information provided, the EHD can make the following findings: <br /> 1. Based on the information provided, the EHD finds that the SSNL Study supports the suitability <br /> for standard OWTS usage for future development on the proposed parcels, pursuant to San <br /> Joaquin County Ordinance Code Title 9, Section 9-1105.2(d), provided the existing and <br /> proposed OWTS and 100% replacement areas can meet all required minimum setbacks from <br /> any water wells. <br /> 2. The water sample data show the well being utilized for drinking water has an elevated level <br /> of nitrate nitrogen of 32.0 mg/L and may not be a suitable source for the potable water supply <br /> for new development. A potable water supply that can provide a consistent source of safe and <br /> clean water adequate for human consumption, cooking, and sanitary purposes for the <br /> proposed project prior to the issuance of building permits (2016 CA Plumbing Code, Section <br /> 601.2). <br /> 1868 E.
