"Guidance for Conducting Remedial Investigations and Feasibility Studies under CERCLA, Interim Final" (October 1988)1
Revises the 1985 guidance on Remedial Investigations (RI) and Feasibility Studies (FS). It reflects provisions of SARA, presents management initiatives to streamline the RI/FS process, and incorporates improvements learned from previous projects. [186 pp]

"Conducting Remedial Investigations/Feasibility Studies for CERCLA Municipal Landfill Sites" (February 1991)
Utilizes the Presumptive Remedy approach for addressing the RI/FS processes at municipal landfills. Defines site characterization strategies, identifies remedial action alternatives, and recommends containment as the preferred remedy. [305 pp]

"Feasibility Study Analysis for CERCLA Municipal Landfill Sites" (August 1994)
Presents an evaluation of the technologies considered in the Feasibility study at 30 municipal landfill sites. The evaluation concludes that certain technologies were routinely screened out based on effectiveness, implementability, or excessive costs. This document is intended to be used as a key reference in the Administrative Record as technical basis for limiting analysis of remedial alternatives to those technologies recommended in the OSER Dirctive 9344.0-49FS entitled "Presumptive Remedy for CERCLA Municipal Landfill Sites."
