III. REMEDIATION PLAN Report/Plan Element A. Evaluation of Remedial Alternatives 1. The remedial alternatives evaluated must be identified, and the rationale for their selection must be provided. In addition, the remediation work plan should describe parameters evaluated for each of the selected alternatives. The parameters should include, but not necessarily be limited to, the following: a. Extent of remediation effort b. Technical feasibility to address physical and chemical characteristics of media c. Projected contamination removal & treatment rates d. Protectiveness of human health e. Cleanup criteria f. Ability of each alternative to achieve cleanup criteria g. Community acceptance h. Anticipated volume of contaminated materials to be treated i. Ease of technology application or implementation j. Dimensions of major technologies & space limitations k. Process parameters l. Clean up time frames m. Transportation distances n. O&M Costs o. Any other special considerations 2. Summarize conclusions for each of the technologies evaluated, and provide reasons each technology would or would not be appropriate 3. Need for treatability study or pilot test. Describe the treatability study or pilot test and the reasons it is required, and provide the following information: a. Proposed study methodology b. Clear statement of treatability study or waste characterization objectives c. Proposed scale of study (e.g., bench, pilot, etc.) d. Data requirements and evaluation e. Pilot plant startup and O&M f. Schedule for pilot study g. Remedial technologies to be tested & equipment required h. Treatability assessment and waste characterization i. Proposed disposal arrangements for wastes caused during remediation, plus approvals & necessary documentation j.

Report/Plan Element B. Selected Remediation Technology ­ If more than one remedial alternative will be used to address different onsite areas, the remediation work plan must describe how the remediation system, as a whole, will work. A flow diagram, conceptual sketch, or other approach should be used to illustrate the components of the remediation system. Major equipment, such as pumps, air strippers, and in-situ treatment equipment, must be indicated. The work plan should include a site map showing areas to be remediated and proposed locations of major equipment. 1. Identify which evaluated technology or combination of technologies will be implemented at the site, including the technical, economic and social acceptance rationales for the final selection. 2. Identify the need for risk assessment and provide: a. Parameters to be addressed b. Proposed risk assessment methodologies c. Potential exposure pathways d. Exposure assumptions e. Environmental fate and transport data f. Tabulated parameters and resulting cleanup levels 3.
