• TPH-g = 10 mg/kg <br /> Acceptable soil concentrations are a function of water quality goals associated with the resid- <br /> ual plume area This is based on using an environmental attenuation factor of 1 and a leach- <br /> ability factor of 10 Tlus assumption was made to establish conservative soil cleanup goals <br /> The aforementioned goals apply to the site during remediation and beyond, however, they <br /> may be modified at any time if it can be shown that changes <br /> • are consistent with the maximum benefit to the people of the State, and, <br /> • will not unreasonably affect present or probable future beneficial uses of <br /> groundwater <br /> For example, at some point in the future it may be advantageous to modify the stated water <br /> quality goals This would be done by showing that the modified goals meet the conditions <br /> above <br /> 3.2 Site Public Health and Safety Goals <br /> According to guidance presented in Title 23, Chapter 16, Article 11 of the California Code of <br /> Regulations (CCR), any remediation approach considered must be designed to mitigate <br /> nuisance conditions and risk of fire or explosion posed by residual impact To assure remedial <br /> objectives address the requirements of Article 11, site-specific public health and safety goals <br /> are necessary The site-specific goal is to eliminate any threat to public health and safety <br /> associated with subsurface petroleum hydrocarbon impact, including the potential threat posed <br /> by nuisance conditions and risk of fire or explosion Additionally, use of, or exposure to <br /> impacted groundwater or soil will be restricted <br /> 3201357B1CAP 8 Apn14, 1995 <br />
