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
http://clu-in.org/studio .
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.

Documents and Web Resources
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
http://www.epa.gov/superfund/resources ... .
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
http://epa.gov/newsroom/perchlorate.pd ... .
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 .
