Phase IV Soil Treatment Standards, May 26, 1998
You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.The LDR Phase IV soil treatment standards, promulgated on May 26, 1998, are specifically designed to encourage cost-effective cleanup of hazardous contaminated soils that are subject to LDRs. Before this final rule was promulgated, soils subject to LDRs were required to comply with traditional technology-based treatment standards developed for processed industrial hazardous waste. These treatment standards often proved to be inappropriate (e.g., not cost effective) and unachievable (e.g., did not account for heterogeneous soil matrices) when applied to hazardous constituents present in soils.
The new soil treatment standards provide more flexible less stringent treatment requirements that are achievable using a variety of non-combustion treatment alternatives. For instance, a site may now choose to reduce hazardous constituents (1) by at least 90 percent of their initial concentration, or (2) meet ten times the applicable universal treatment standard.
As well, for the first time, we are introducing site-specific risk-based decision making into the LDR program via a site-specific risk-based treatability variance, This variance allows Superfund and RCRA Corrective Action sites, on a site-specific basis, to apply for a risk-based treatability variance that essentially sets LDR treatment standards at the site-specific risk-based numbers.

- Soil Treatment Technologies - Includes links to guidance documents, databases, and other resources.
- Corrective Action Management Tools - If you want to learn more about the corrective action program, this is a good place to start.
- Best Management Practices (BMPs) for Soil Treatment Technologies: Suggested Operational Guidelines to Prevent Cross-media Transfer of Contaminants During Clean-up Activities (May 1997) (PDF) (166 pp, 1.2MB) - This document provides guidance on how to design and conduct soil remediation activities at RCRA and other hazardous waste sites so that transfers of contaminants from contaminated soil to other media are minimized.
- RCRAInfo is a national program management and inventory system of RCRA hazardous waste handlers. RCRAInfo captures identification and location data for handlers and a wide range of information on treatment, storage and disposal facilities regarding permit/closure status, compliance with Federal and State regulations, and cleanup activities.
- EPA REACH IT is a new system
designed to search, view, download, and print information about innovative
remediation and characterization technologies. This database includes
- technologies that treat, characterize or monitor a particular contaminated medium,
- service providers,
- and remediation sites.
- The Clu-in Hazardous Waste Clean-up Information site highlights innovative treatment technologies. This database offers information on programs, organizations, publications, and other tools that can help facilitate the remediation process.
- The Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) Search lists Superfund sites that have been listed on the National Priorities List (NPL). You can search for information by area or site.
- HazDat, the Agency for Toxic Substances and Disease Registry's Hazardous Substance Release/Health Effects Database, is the scientific and administrative database that provides access to information on the release of hazardous substances from Superfund sites or from emergency events. This databases also lists the effects of hazardous substances on the health of human populations.
- Federal Remediation Technologies
Increasing the cost effectiveness of site remediation is a national
priority. The selection and use of more cost-effective remedies requires
better access to data on the performance and cost of technologies used
in the field.
To make data more widely available, member agencies of the Federal Remediation Technologies Roundtable are working jointly to publish case studies of full-scale remediation and demonstration projects. At this time, the Roundtable is publishing seven additional volumes, primarily focused on soil and groundwater cleanup.

- Hazardous Waste Identification Final Rule for Contaminated Media (November 30, 1998) - As part of President Clinton's March 1994 environmental regulatory reform initiative, the United States Environmental Protection Agency (EPA) is issuing new requirements for Resource Conservation and Recovery Act (RCRA) hazardous remediation wastes treated, stored or disposed of during cleanup actions.

- Phase IV Final Rule -- Clarification of Effective Dates Memo - (October 19, 1998) (PDF) (18 pp, 50K, About PDF) - This memorandum explains when each provision of the rule becomes effective, depending upon which part of the governing statute it implements, whether the new provision is more or less stringent than an existing one, and the status of each state's process of becoming authorized to implement hazardous waste regulations.
- Management of Remediation Waste under RCRA (October 1998) (PDF) (13 pp, 46K) - Rapid clean up of RCRA corrective action facilities and Superfund sites is one of the Agency's highest priorities. To assist you in successfully implementing RCRA requirements for remediation waste, this memorandum consolidates existing guidance on the RCRA regulations and policies that most often affect remediation waste management.
