The report shall include evaluation of non-point source of hazardous <br /> materials, including agricultural chemical residues, as well as potential point sources,such as <br /> fuel storage tanks,septic systems,or chemical storage areas. If the report indicates there is <br /> contamination,corrective action shall be taken,as recommended in the report and concurred <br /> with by Environmental Health prior to submittal of tentative map(San Joaquin County <br /> Development Title, Section 9-905.12(a)(c)). <br /> (J Environmental Health Department requires a Soil Suitability/Nitrate Loading Study <br /> indicating that the area is suitable for septic tank usage.
