Happy New Year! Are your environmental systems Y2K compliant?
Since December 1, TechDirect gained 199 new subscribers for a
total of 5319. Welcome to all the newcomers! We hope this service
continues to be beneficial. Let us know your ideas for its
improvement.
The Hazardous Waste Clean-Up Information (CLU-IN) homepage
has undergone a significant facelift. It has many new features to
guide you to new charaterization and remediation technology
information. In addition, CLU-IN is switching to a new address at
httD://ciu-in.ora. The old address, http://clu-in.org, will continue to work
for a few more months. PLEASE UPDATE YOUR BOOKMARKS
AND LINKS TO THE CLU-IN SITE TO HTTP://CLU-IN.ORG.
Please let us know if you like our changes to CLU-IN.
We have added a new feature on the TechDirect page in the new
CLU-IN to help you subscribe, unsubscribe or update your
TechDirect subscription address. We hope this makes life a little
easier. Help us keep your subscription information current. See

EPA Policy
Proposed TSCA 403 Soil Lead Hazard and OSWER?s Lead-in-Soils
Policy (EPA 540-F-98-061). This proposed policy was issued jointly
by the EPA Office of Prevention, Pesticides and Toxics (OPPTS)
and the Office Of Solid Waste and Emergency Response (OSWER).
It addresses issues that have arisen about the relationship between
the proposed TSCA 403 rule and OSWER?s Interim Soil Lead

Assessment and Remediation of Contaminated Sediments
(ARCS) Program: Guidance for In Situ Subaqueous Capping of
Contaminated Sediments (EPA 905-B-96-004)
This document was published by the U.S. EPA Great Lakes National
Program Office. It provides technical guidance for subaqueous, in
situ capping as a remediation technique for contaminated
sediments. It provides descriptions of the processes, identification of
the design requirements, and a recommended sequence for design

Technology Evaluation Report: Technologies for Dense
Nonaqueous Phase Liquid Source Zone Remediation (TE-98-02).
This report was published by the Ground Water Remediation
Technologies Analysis Center (GWRTAC). Dense nonaqueous
phase liquids (DNAPLs) are present at numerous commercial and
government sites. Several technologies have demonstrated the
ability for fairly rapid removal of mass from DNAPL source zones;
others have shown the ability to treat dissolved phase
contamination. This report evaluates those technologies shown to
have potential for remediation of DNAPL source zones [December

This CD-ROM was developed by the U.S. EPA National Exposure
Research Laboratory. It contains electronic documents and
computer programs related to the characterization of hazardous
waste sites [October 1998], For copies, contact (800) 490-9198 or

Site Characterization for Explosives Contamination at a Military
Firing Range Impact Area (Special Report 98-9). This report was
published by the Cold Regions Research and Engineering
Laboratory of the U.S. Army Corps of Engineers. This project had
three objectives: provide information on status of explosives
contamination at FT Ord impact ranges, develop protocols for more
extensive site characterization, and evaluate a draft protocol for
preparing a site specific full-scale sampling plan [August 1998, 45
pages]. View or download at http://www.crre! .usace.armv.mil/techDub/CRREL Re ports/index .html

Detecting Primary Metallic Explosives with a Portable X-Ray
Fluorescence Spectrometer (Special Report 97-8)
The purpose of this study was to select and test a XRFinstrument
for screening sites where metallic primers may be present. The
selection criteria used in this process included appropriate metal
sensitivity and aelectivity, area of effective sample analysis,
portability and user friendliness. Laboratory experiments were
designed to evaluate qualitatively the performance of the selected
XRF system under a variety of conditions [April 1997, 14 pages].

List of Leak Detection Evaluations for Underground Storage
Tank Systems - Fifth Edition (EPA 510-B-98-005). This publication
was reproduced by EPA Office of Underground Storage Tanks. The
list is based on reviews by the independent National Workgroup on
Leak Detection Evaluations consisting of state and EPA UST
program staff,. Therefore, this list is not an EPA list. The publication
contains information on underground storage tank and piping leak
detection system evaluations that have met certain criteria [October

Conferences and Symposia
Natural Attenuation of Chlorinated Solvents in Groundwater, New
Orleans, LA, January 12-13, 1999. This course is sponsored by the
Interstate Technology Regulatory Cooperation (ITRC) workgroup
and the industrial partners of the Remediation Technologies

business and industry solve environmental problems. The program
is designed to bring together representatives from across the
country and the world to address such topics as innovative
environmental technologies, brownfields cleanup using innovative
treatment technologies, technology verification/certification,
electronic data exchange and partnering. Through panel
discussions, presentations, exhibits and technology demonstrations
we will provide an opportunity to share information, showcase
technologies and identify new technology needs in the United States
and internationally. For more information, visit: http ://www.state. n i. us/dep/srp.

Wanted!! Direct Push Data Sets. Direct push (DP) collection of
ground water samples is being used extensively for screening
purposes, but not for more rigorous purposes such as site listing or
cleanup monitoring. EPA is seeking ground water data sets from
sites with both DP and monitoring well samples for a study designed
TechDirect: January 1, 1999

to determine when and how DP can be used for collecting definitive,
legally defensible data. If you have data sets comparing Direct Push
samples to conventional well samples and are interested in suppling
that information to EPA for this study, please contact Randall Ross
at ross.randall@epa.gov. For more information on this study, see
the Project Description at http://clu-in.org/techdrct/techpubs.htm.
