' Screening Criteria <br />' Alternatives for the remediation of hydrocarbon-containing soils were <br /> screened and evaluated based on the following four criteria <br /> • Effectiveness, <br /> • Implementability, <br /> • Cost, and <br />' • Timeliness of Implementation <br /> The effectiveness, 2mplernentability, and cost criteria are components of <br />' the National Contingency Plan (NCP) and were used because they <br /> provide a systematic method of alternatives evaluation Timeliness of <br /> implementation was included as an additional criterion to accommodate <br /> site-specific requirements Each criterion is described as follows <br /> • The effectiveness criterion evaluates the ability of the alternative to <br /> address the specific chemical compounds present at the site It <br /> measures the reliability and effectiveness of the alternative for <br /> treatment or disposal of the hydrocarbons at the site This criterion <br /> also evaluates the uncertainties associated with the long-term <br /> reliability of the alternative <br /> The implementability criterion evaluates the ability of the alternative <br /> to be implemented based on technical and operating experience, <br /> physical site constraints, availability of services, and administrative <br /> limitations <br />' . The cost criterion evaluates the major capital cost items and operating <br /> cost items associated with implementation of the alternative in the <br /> following evaluation, the cost of an alternative was based on past <br />' experience and vendor quotes and should be used for comparison <br /> purposes only <br /> • The timeliness criterion evaluates the ability of the alternative to meet <br /> governmental or regulatory agency-imposed deadlines A remedial <br />' action may be required in a relatively short period of time, therefore, it <br /> must be possible to implement the selected alternatives within this <br /> time frame <br /> 1 <br /> 4-2 <br /> 1 <br />
