Open Solicitation  
  
The Department of Defense (DoD) through the Environmental  
Security Technology Certification Program (ESTCP), supports the  
demonstration and validation of environmental technologies that  
address priority DoD environmental requirements. The goal of  
ESTCP is to transition mature environmental Science and  
Technology projects through the demonstration/validation phase,  
thereby enabling promising technologies to receive regulatory and  
DoD end user acceptance and to be fielded and commercialized  
more rapidly.  ESTCP is seeking pre-proposals from DoD  
organizations as well as non-DoD Federal organizations and the  
private sector.  PRE-PROPOSALS ARE DUE BY THURSDAY,  
MARCH 09, 2006. Detailed instructions for DoD, Non-DoD  
federal, and BAA proposers (i.e., details regarding the program's  
objectives, proposal submission requirements, the evaluation of  
proposals, and the individual topic areas) are available on the  
ESTCP website at http://www.estcp.org/opportunities .  
  
Internet Seminars  
  
ITRC Strategies for Monitoring the Performance of DNAPL  
Source Zone Remedies - February 7.  This training discusses  
issues surrounding the assessment of remediation performance at  
DNAPL sites where the source zone is being targeted for treatment.  
It is based on the ITRC document titled, Strategies for Monitoring  
the Performance of DNAPL Source Zone Remedies. Specific  
issues dealing with monitoring the performance of various DNAPL  
source zone remediation technologies are discussed.   Elements of  
a robust performance monitoring program are described including  
the need to establish appropriate performance goals and metrics  
well in advance.  To register, see http://www.itrcweb.org or

ITRC Guidance for Characterization, Design Construction  
and Monitoring of Mitigation Wetlands - February 9.  This  
seminar is the second in a series of wetland trainings beginning  
with the ITRC Technical and Regulatory Guidance Document for  
Constructed Treatment Wetlands (WTLND-1).  To improve the  
success of wetland mitigation projects, this training presents  
comprehensive guidance for regulators, environmental  
professionals, or owners to use to understand, characterize, design,  
construct, and monitor mitigation wetlands.  To register, see  
http://www.itrcweb.org or http://clu-in.org/studio .  
  
ITRC Radiation Site Cleanup: CERCLA Requirements and  
Guidance - February 23.  The focus of this ITRC training is  
EPA's guidance for remediating radioactively contaminated sites,  
which can facilitate cleanups that are consistent with how chemical  
contaminants are addressed, except where technical differences  
posed by radiation are addressed.  This course also discusses long  
term stewardship (LTS) challenges related to the large  
radioactively contaminated sites. This understanding of LTS issues  
is integral to the cleanup process and decisions made at the  
radiation sites.  To register, see http://www.itrcweb.org or  
http://clu-in.org/studio .  
  
ITRC Triad Approach: A New Paradigm for Environmental  
Project Management - February 28.  This seminar discusses the  
relationship of the Triad to previous regulatory guidance, and  
offers a discussion of issues that may affect stakeholders.  The  
ITRC guidance document, Technical and Regulatory Guidance for  
the Triad Approach: A New Paradigm for Environmental Project  
Management (SCM-1), serves as the basis for this training course.

Contaminated Sediment Remediation Guidance for Hazardous  
Waste Sites (EPA-540-R-05-012).  This guidance was issued by  
the EPA Office of Solid waste and Emergency Response.  It  
provides technical and policy guidance for project managers and  
management teams making remedy decisions for contaminated  
sediment sites.  The guidance is primarily intended for federal and  
state project managers considering actions under CERCLA,  
although technical aspects of the guidance are also intended to  
assist project managers addressing sediment contamination under  
RCRA. Many aspects of this guidance also will be useful to other  
governmental organizations and potentially responsible parties  
(PRPs) that may be conducting a sediment cleanup.  Although  
aspects related to site characterization and risk assessment are  
addressed, the guidance focuses on considerations regarding  
feasibility studies and remedy selection for contaminated sediment  
(December 2005, 236 pages).  View or download the complete  
document or sections at

EPA Assessment Guidance for Perchlorate.  The EPA Office of  
Solid Waste and Emergency Response issued new guidance for  
cleaning up perchlorate contamination recommending a  
preliminary clean-up goal for perchlorate of 24.5 parts per billion  
in water.  EPA's guidance is derived from the agency's reference  
dose for perchlorate which is based on the 2005 recommendations  
and conclusions of the nation's foremost science advisory  
committee (National Academy of Sciences).  This preliminary goal  
is a starting point for an evaluation of site-specific conditions.  
Consistent with current practice, final clean-up determinations  
should take site-specific information into consideration. This  
action offers clear guidance to site managers to help ensure  
national consistency in evaluating perchlorate in light of widely  
varying state guidance. This decision was based on the best  
available science and will be updated as new information becomes  
available (January 2006, 3 pages).   View or download at

Edible Oil Barriers for Treatment of Perchlorate Contaminated  
Groundwater (ER-0221).  This report was published by the DoD  
Environmental Security Technology Certification Program (ESTCP).  
This final technical report documents the demonstration of emulsified  
edible oil barriers for groundwater remediation at a confidential  
perchlorate site in Maryland. The general purpose of the demonstration  
was to evaluate the efficacy of emulsified oils for treating perchlorate  
contaminated groundwater. A second demonstration was  
performed as part of this project to evaluate the use of emulsified  
oils for remediation of chlorinated solvent impacted groundwater at  
the Charleston Naval Weapons Station (NWS) in South Carolina.  
The work at the Charleston NWS is still ongoing and will be  
reported separately. In addition, a technical protocol document is  
being written under this demonstration project which describes in  
detail the use of emulsified oils for enhanced anaerobic  
bioremediation of perchlorate and chlorinated solvents (November  
2005, 155 pages).  View or download at http://clu-in.org/techpubs.htm .
