R10/71-51-1C 74 Initial Screening of Remedial Action Options_Identified Each option listed in Table 16 were subjected to a screening for fundamental characteristics that may eliminate it from further consideration using the following screening factors o The public health and environmental protection provided by technology, o The ability of the technology to produce a desired result in a stipulated time ' frame, o Feasibility of the technology, and ' o The acceptability of the technology in the light of public and institutional P tY gY 9 ' considerations The purpose of the screening is to eliminate technologies with obvious fatal flaws up-front ' so that they do not have to be carried through the detailed analyses in Section 7 5 An initial screening fact rating scheme has been developed and presented in Table 17 An alternative that received a I" in any of the four categories will be eliminated and will not be carried through the detailed analyses A public health and environmental protection criteria reviews the technology's ability to protect public health in light of treatment technology or disposal failure This is necessary because some alternatives may be able to provide greater degrees of reliability than other alternatives because of treatment type complexities, operator requirements or other specific factors The ability of the technology to produce the desired results in a stipulated time frame tests the alternative's implementability given the current environment Alternatives that rely on unproven or innovative technologies or disposal options that require additional permitting or field verification studies may be more time consuming to implement that other alternatives The feasibility of the technology tests the alternative's ability to meet the specific site, ' media or contaminant conditions This criteria tests the alternative 's ability to provide a feasible technology Alternatives that rely on unproven or innovative technologies or have not demonstrated to be effective against contaminants existing at the site will tend ' to receive lower scores than technologies shown to be effective in treating contaminants at the Caltrans Shop-10 site 32
