Use of Soil Cleanup Criteria in 40 CFR Part 192 as Remediation Goals for CERCLA Sites. (EPA Directive # 9200.4-25). This EPA memorandum addresses the use of the soil cleanup criteria in 40 CFR Part 192 when setting remediation goals at CERCLA sites with radioactive contamination. In particular, it clarifies the intent of 40 CFR Part 192 in setting remediation levels for subsurface soil. It does not address the applicability or intent of other standards contained in 40 CFR Part 192, nor does it address setting remediation goals for contaminated media other than soil [February 1998, 5 pages].

Natural Attenuation of Chlorinated Volatile Organic Compounds in a Freshwater Tidal Wetlands, Aberdeen Proving Ground, Maryland, (Water Resources Investigation Report 97-4171). This report was produced by the U.S. Geological Survey in coordination with the U.S. Army Garrison, Aberdeen Proving Ground. The purpose of this report is to describe the natural attenuation of VOCs in a wetland study area. Biodegradation and sorption were found to be significant natural attenuation mechanisms for dechlorination [Fall 1997, 105 pages].For copies, contact (303) 202-4700, the USGS Branch of Information Services, P.O.

Expediting Clean-Up and Redevelopment of Brownfields: Addressing the Major Barriers to Private Sector Involvement -- Real or Perceived. This report was submitted to EPA by the Environmental Financial Advisory Board (EFAB). This report was submitted to EPA by the Environmental Financial Advisory Board (EFAB). This report identifies what the EFAB believes are the major barriers (whether legal, financial, practical, real or perceived) that currently discourage or impede the private sector from participating in, and investing financial resources in the clean-up and redevelopment of, sites that are, or are potentially subject to, the legal jurisdiction of the Superfund program. The report focuses on four concerns that the EFAB found were most frequently identified by the private sector (e.g., real estate developers, bankers) as barriers to participation in redevelopment of "Brownfields: Crucial Linked Issues -- Delineating States' and EPA's Roles, and Determining Feasible Clean-Up Standards; Protecting Against Liability for Third-Party Claims; Utilizing Available Federal Financial Incentives; and Obtaining Priority Clean-Ups [December 1997, 15 pages].

Bioremediation Of Soils Using Windrow Composting (CEGS 02191). This document, developed by the U.S. Army Corps of Engineers, covers the requirements for reductions of the concentrations of organics in soil by bioremediation using windrow composting. This guide specification was developed based on the use of composted to treat explosives-contaminated soil. The same process is believed to be applicable to other organic contaminated soil [February 1998, 46 pages]. View or download at http://www.hnd.usace.army.mil/techinfo/

Design Guidance for Application of Permeable Barriers to Remediate Dissolved Chlorinated Solvents. This guidance manual was developed by the US Air Force Armstrong Laboratory/Environics Directorate with support from the Interstate Technology and Regulatory Cooperation (ITRC) workgroup. This guidance addresses design, emplacement, and monitoring of permeable barriers in various hydrogeologic settings [February 1997, 177 Pages].

A Guideline for Dynamic Workplans and Field Analytics: The Keys to Cost-Effective Site Characterization and Cleanup. This report was developed by Tufts University in cooperation with U.S EPA Region I. A number of governmental, academic, and private sector organizations have articulated innovative strategies for performing hazardous site characterization and remediation in a more efficient and cost-effective manner. Certain basic elements are common to all these strategies, and the cost-effectiveness and practicality of this approach has been demonstrated in a number of settings.

Every month we encounter between 20-30 undeliverable addresses. In some instances, it may be due to the addressees' servers being down that particular day. It may be that the addressees' have left their positions or that the addresses have changed. It could be some other undetectable problem in the ether. These are distinguishable from the few people who elect to unsubscribe.

Every month, we wrestle with what to do with the undeliverable addresses. In the past we deleted them. We have decided to leave them on the list for 2 additional deliveries. If the address remains undeliverable 3 months in a row, it will be deleted.

I bring this up because some subscribers have probably been deleted unknowingly. If so, we apologize. You should receive a message on or around the first of each month. If you ever come to the realization that you are no longer receiving TechDirect, it may be for one of the reasons mentioned above. Please help us keep current should your e-mail address change. Let me know of any inconsistencies you've encountered in the electronic delivery of TechDirect. Thank you.
