guidance resources related to the assessment and remediation of    
contaminated soil, sediments and ground water.

Open Solicitation   
ESTCP Solicitation. The Department of Defense (DoD)    
Environmental Security Technology Certification Program (ESTCP)    
released its annual solicitation on January 7, 2010. This    
solicitation requests pre-proposals via Calls for Proposals to    
DoD organizations and Federal (Non-DoD) organizations as well as    
a Broad Agency Announcement (BAA) for Private Sector    
organizations. The DoD Call for Proposals requests pre-proposals    
related to: (1) environmental restoration; (2) munitions    
management; (3) sustainable infrastructure; (4) weapons systems    
and platforms; and (5) energy. The Non-DoD Federal Call for    
Proposals and the BAA request pre-proposals in the following    
topics only: (1) protection and remediation of contaminated    
groundwater; (2) military munitions detection, discrimination,    
and remediation; (3) ecosystem service methodologies and tools    
for DoD installations; and (4) energy efficiency and renewable    
energy for DoD installations. The submission deadline for    
pre-proposals is March 4, 2010. View more information about the    
solicitation and detailed instructions at .   
Upcoming Live Internet Seminars   
2010 CARE RFP National Webcast - February 2, 23, 26, 2010,    
1:00PM-3:00PM EST (18:00-20:00 GMT). This webcast is an    
opportunity for potential applicants to the 2010 CARE    
cooperative agreement grant program to learn more about the    
program and ask questions about the Request for Proposals issued    
in December 2009. For more information and to register, see .   
ITRC In Situ Bioremediation of Chlorinated Ethene - DNAPL Source    
Zones - February 9, 2010, 2:00PM-4:15PM EST (19:00-21:15 GMT).    
Treatment of dissolved-phase chlorinated ethenes in groundwater    
using in situ bioremediation (ISB) is an established technology;    
however, its use for DNAPL source zones is an emerging    
application. This training course supports the ITRC Technical    
and Regulatory Guidance document In Situ Bioremediation of    
Chlorinated Ethene: DNAPL Source Zones (BioDNAPL-3, 2008). This    
document provides the regulatory community, stakeholders, and    
practitioners with the general steps practitioners and    
regulators can use to objectively assess, design, monitor, and    
optimize ISB treatment of DNAPL source zones. For more

ITRC Enhanced Attenuation of Chlorinated Organics: A Site    
Management Tool - February 11, 2010, 11:00AM-1:00PM EST    
(16:00-18:00 GMT). This training on the ITRC Technical and    
Regulatory Guidance for Enhanced Attenuation: Chlorinated    
Organics (EACO-1, 2008) describes the transition (the bridge)    
between aggressive remedial actions and MNA and vise versa.    
Enhanced attenuation (EA) is the application of technologies    
that minimize energy input and are sustainable in order to    
reduce contaminant loading and/or increase the attenuation    
capacity of a contaminated plume to progress sites towards    
established remedial objectives. Contaminant loading and    
attenuation capacity are fundamental to sound decisions for    
remediation of groundwater contamination. This training explains    
how a decision framework which, when followed, allows for a    
smooth transition between more aggressive remedial technologies    
to sustainable remedial alternatives and eventually to Monitored    
Natural Attenuation. This training will demonstrate how this    
decision framework allows regulators and practitioners to    
integrate Enhanced Attenuation into the remedial decision    
process. For more information and to register, see or .   
ITRC Phytotechnologies - February 25, 2010, 11:00AM-1:15PM EST    
(16:00-18:15 GMT). This training familiarizes participants with    
ITRC's Phytotechnology Technical and Regulatory Guidance and    
Decision Trees, Revised (Phyto-3, 2009). This document provides    
guidance for regulators who evaluate and make informed decisions    
on phytotechnology work plans and practitioners who have to    
evaluate any number of remedial alternatives at a given site.    
This document updates and replaces Phytoremediation Decision    
Tree (Phyto-1, 1999) and Phytotechnology Technical and    
Regulatory Guidance Document (Phyto-2, 2001). It has merged the    
concepts of both documents into a single document. This guidance    
includes new, and more importantly, practical information on the    
process and protocol for selecting and applying various    
phytotechnologies as remedial alternatives. For more information

ITRC Decontamination and Decommissioning of    
Radiologically-Contaminated Facilities - March 4, 2010,    
11:00AM-1:15PM EST (16:00-18:15 GMT). This training introduces    
ITRC's Technical/Regulatory Guidance, Decontamination and    
Decommissioning of Radiologically-Contaminated Facilities    
(RAD-5, 2008), created by ITRC's Radionuclides Team. The    
curriculum is composed of four modules: Introduction and    
Regulatory Basis for Decontamination and Decommissioning (D&D),    
Factors for Implementing D&D, Preliminary Remediation Goal (PRG)    
Calculators, and Case Studies and Lessons Learned. For more

New Documents and Web Resources   
New CLU-IN Sediments Section. EPA's Office of Superfund    
Remediation and Technology Innovation has released a new CLU-IN    
section that compiles available information related to    
contaminated sediments. Sediments are defined as the organic and    
inorganic materials found at the bottom of a water body.    
Sediments may include clay, silt, sand, gravel, decaying organic    
matter, and shells among other things, but exclude anthropogenic    
debris, such as vehicle tires. The classes of contaminants that    
are most common in sediment contamination are pesticides, PCBs,    
PAHs, and to a lesser extent dissolved phase chlorinated    
hydrocarbons. With the right geochemical conditions heavy metals    
and metalloids can also occur in sediments or precipitate into    
them. The most common sediment treatment technologies are    
monitored natural recovery, in situ capping, dredging, and    
excavation. EPA will maintain this section by adding new    
resources as they become available. View and use at .   
CLU-IN Vendor Directory Updated. The CLU-IN Vendor Directory,    
available as part of CLU-IN's Vendor and Developer Support area,    
has been updated with vendor submissions received through the    
end of 2009. Site owners, regulators, researchers, and other    
environmental professionals are encouraged to use the directory    
to identify vendors and services to meet their remediation and
