All remedial action plans prepared or approved pursuant to this article shall be based upon Sections 78855 and 78860 and Subpart E of the National Oil and Hazardous Substances Pollution Contingency Plan (40 C.F.R. 300.400 et seq.), as amended, and upon all of the following factors, to the extent that these factors are consistent with these federal regulations and do not require a less stringent level of cleanup than these federal regulations:
(a)Health and safety risks posed by the conditions at the site. When considering these risks, the department or the regional board shall consider scientific data and reports that may have a relationship to the site.
(b)The effect of contamination or
pollution levels upon present, future, and probable beneficial uses of contaminated, polluted

All remedial action plans prepared or approved pursuant to this article shall be based upon Sections 78855 and 78860 and Subpart E of the National Oil and Hazardous Substances Pollution Contingency Plan (40 C.F.R. 300.400 et seq.), as amended, and upon all of the following factors, to the extent that these factors are consistent with these federal regulations and do not require a less stringent level of cleanup than these federal regulations:
(a)
Health and safety risks posed by the conditions at the site. When considering these risks, the department or the regional board shall consider scientific data and reports that may have a relationship to the site.
(b)
The effect of contamination or
pollution levels upon present, future, and probable beneficial uses of contaminated, polluted, or threatened resources.
(c)
The effect of alternative remedial action measures on the reasonable availability of groundwater resources for present, future, and probable beneficial uses. The department or the regional board shall consider the extent to which remedial action measures are available that use, as a principal element, treatment that significantly reduces the volume, toxicity, or mobility of the hazardous substances, as opposed to remedial actions that do not use this treatment. The department or the regional board shall not select remedial action measures that use offsite transport and disposal of untreated hazardous substances or contaminated materials if practical and cost-effective treatment technologies are available.
(d)
Site-specific characteristics, including the
potential for offsite migration of hazardous substances, the surface or subsurface soil, and the hydrogeologic conditions, as well as preexisting background contamination levels.
(e)
Cost-effectiveness of alternative remedial action measures. In evaluating the cost-effectiveness of proposed alternative remedial action measures, the department or the regional board shall consider, to the extent possible, the total short-term and long-term costs of these actions and shall use, as a major factor, whether the deferral of a remedial action will result, or is likely to result, in a rapid increase in cost or in the hazard to public health or the environment posed by the site. Land disposal shall not be deemed the most cost-effective measure merely on the basis of lower short-term cost.
(f)
The potential environmental impacts of alternative remedial action measures, including, but not
limited to, land disposal of the untreated hazardous substances as opposed to treatment of the hazardous substances to remove or reduce its volume, toxicity, or mobility prior to disposal.
