"ARARs Fact Sheet: Compliance with the Clean Air Act and Associated
Air Quality Requirements" (September 1992)
Provides updated guidance on compliance with the Clean Air Act, as amended November 1990, and related air quality rules under other environmental statutes. Addresses statutory and regulatory changes that have occurred subsequent to the publication of the CERCLA Compliance with other Laws Manual, Parts I & II (1989). [28 pp]

"Principles for Managing Contaminated Sediment Risks at Hazardous
Waste Sites"1 (February 2002)
Presents eleven risk management principles to use as guidelines for site assessment and response when addressing contaminated sediment sites. This directive is consistent with the strategies of the NRC 2001 report "A Risk Management Strategy for PCB-Contaminated Sediments." Headquarters consultation requirements are included. [11 pp]

"In Situ Treatment of Contaminated Sediments" (December 1998)
Provides a summary of in situ treatment technologies for contaminated sediments written by a National Network of Environmental Management Studies Fellow. Contains data gathered from a range of sources including project documents, periodicals, Web pages, and personal communication. The sources were not independently confirmed. [25 pp]

A Risk-Management Strategy for PCB-Contaminated
At the request of Congress, EPA commissioned the National Research Council to investigate contaminated sediment site strategies and provide recommendations for addressing such sites. Provides a risk-based framework for developing and implementing strategies to manage PCB-contaminated sediments. Although focused on PCBs, much of the information is applicable to other contaminants. You may view or order the report from the National Academy Press Web site for a fee. (446 p.)
Guide to GLNPO
Assessment and Remediation of Contaminated Sediments (ARCS) Reports
ARCS was an integrated program for the development and testing of assessment and remedial action alternatives for contaminated sediments. Provides technical reports containing results of assessments of contaminated sediments by the Great Lakes National Program Office (GLNPO) of the U.S. EPA between 1988 and 1994. Although the studies were focused on specific sites, these reports contain information applicable to any contaminated sediment site.
EPA Technology Transfer Highlights
To access Remediation of Contaminated Sediments, select "Browse Pub. Catalog" from the sidebar and enter the EPA Document Number (EPA/625/6-91/028). The Handbook was published by ORD to provide guidance on approaches for remediating contaminated sediment sites. Topics covered include physical/chemical characteristics of sediments, sediment toxicity assessment methods, sampling methods, dredging techniques, pretreatment, treatment technologies, and disposal and containment options. Data from sediment treatability studies for various technologies are provided.
Tool for screening contaminated National Priorities List (NPL) sites that are not affected with radioactive contaminants. The Soil Screening Guidance (SSG) presents a tiered framework for developing risk-based, soil screening levels (SSLs) for protection of human health. This page provides links to several soil screening doucments available.
Screening Guidance for Radionuclides
Provides a framework for developing soil screening levels (SSLs) for radionuclides, focusing primarily on a simple methodology for developing site-specific screening levels, but also including generic soil screening levels and detailed models for more complete site conditions. This page contains links to several technical and guidance doucuments.
"Presumptive Remedy for Metals-in-Soils Sites" (September 1999)
Identifies a presumptive remedy for metals-in-soil sites, and summarizes technical factors (including limitations on the applicability of this directive) that should be considered when selecting a presumptive remedy for these sites. Development has been a joint effort between the EPA and the Department of Energy (DOE). [48 pp]
