F <br /> ODUCTIONssues my Nitrate Loading Study findings concerning three parcels operated by Mr. <br /> tti, which is collectively referred to as "Bogetti's Orchard." A General Plan and Zone Reclassification is proposed for this project so that certain existing, and <br /> potential future businesses can be brought into conforming use. A Nitrate Loading Study was <br /> required by the San Joaquin County Department of Environmental Health(EHD) under <br /> Community Development Title Chapter 9-1105.2 (d)1-5 before the General Plan Amendment and <br /> Zone Reclassification can be petitioned. This Study complies with the standards and specifications <br /> promulgated for completion of a Nitrate Loading Study. The Environmental Health Department <br /> requires Nitrate Loading and Soil Suitability Studies for projects in unsewered and currently nitrate <br /> affected areas, or for projects that may potentially impact the underlying groundwater with nitrate. <br /> I have completed and submitted a Soil Suitability Study to EHD for this project(See Report Number <br /> SSS-02.02). This Soil Suitability Study addressed the two subject parcels north of State Route 132 <br /> (APNs 255-25-07 and 255-25-09). The third subject parcel addressed for this Study is south of State <br /> Route 132 (APN 255-26-13). It is proposed to be developed into a Truck Stop facility. Therefore, it <br /> must comply with the Enviromnenta�t Department Sewage Standards, specifically Section 10- <br /> "Requirements for Waste Disposal for New Land Developments." This report incorporates both Soil <br /> Suitability and Nitrate Loading Study requirements for parcel 255-26-13. The proposed Truck Stop <br /> is also to incorporate approximately 9 acres to the east of the subject parcel. These 9 acres are in <br /> Stanislau�ounLx- <br /> The Truck Stop facility will have a self-supporting septic system. The EHD will require that the <br /> facility must have a sewage treatment system, such as a "package treatment Want," etc. that will <br /> treat sewage effluent to the degree warranted, for that portion of the facility that is in San Joaquin <br /> County. Therefore, thi itrate Loading Study does not Inco orate the nitrate loading <br /> calculatio ificall for this ro ose act The intention of this Study was to gather data <br /> and information, and determine baseline concentrations. <br /> The primary concern of nitrate in drinking water is that high concentrations in food or drinking <br /> water can cause methemoglobinemia in infants, and it can also induce abortion or death in cattle. <br /> This disease occurs through a series of complex chemical reactions within the hemoglobin in the <br /> blood. Only infants and young children are susceptible. Although this disease is extremely rare, <br /> nitrate can also potentially cause other health concerns. Scientific studies suggest that nitrate <br /> may produce carcinogenic effects in humans. Nitrate concentrations in water can be expressed <br /> two ways: 1.)As the weight of the nitrate molecule, which is one atom of nitrogen and three <br /> atoms of oxygen for an atomic weight of 62 units. Or, 2.)Nitrate can be expressed as the amount <br /> of the nitrogen atom itself. The ratio of weight of the nitrate molecule (NO3) to the atom(N) is <br /> 62/14 or approximately 4.5. The U.S.E.P.A. has established the Maximum Contaminant Level <br /> (MCL) of nitrate in drinking water at 45 mg/1 as nitrate. Due to the ratio described above,the <br /> MCL is sometimes reported as 10 mg/1 as nitrate-nitrogen. <br /> 1 <br /> Chesney Consulting <br />
