ITRC Issues Request for Proposals (RFP) for 2013 Projects. The Interstate Technology & Regulatory Council (ITRC) requests proposals for 2013 ITRC projects.
ITRC would like to focus proposals on the following topical areas: site characterization, sampling, and monitoring; soil, groundwater, and sediments contamination;
military munitions; long term stewardship and land use controls; and watershed management. Proposals on other topics will be considered, but preference
will be given to those that address one of these areas. Proposals are due electronically to Anna Willett, ITRC Director (email@example.com) by 5 pm Eastern time
on Friday, February 10, 2012. For more information and a project proposal form, see http://www.itrcweb.org/planning.asp .

ITRC Biofuels: Release Prevention, Environmental Behavior, and Remediation - December 6, 2011, 2:00PM-4:15PM EST (19:00-21:15 GMT). This training,
which is based on the ITRC's Biofuels: Release Prevention, Environmental Behavior, and Remediation (Biofuels-1, 2011), focuses on the differences between
biofuels and conventional fuels specific to release scenarios, environmental impacts, characterization, and remediation. The trainers will define the
scope of the potential environmental challenges by introducing biofuel fundamentals, regulatory status, and future usage projections. Participants will
learn how and when to use the ITRC biofuels guidance document for their projects. They will understand the differences in biofuel and petroleum behavior; become
familiar with the biofuel supply chain, potential release scenarios and release prevention; be able to develop an appropriate conceptual model for the investigation
and remediation of biofuels; and select appropriate investigation and remediation strategies. For more information and to register, see http://www.itrcweb.org
or http://clu-in.org/live .
ITRC LNAPL Training Parts 1, 2, and 3 - December 8, 13, 15, 2011. Light non-aqueous phase liquids (LNAPLs) are organic liquids such as gasoline, diesel, and
other petroleum hydrocarbon products that are immiscible with water and less dense than water. LNAPLs are important because they are present in the subsurface
at thousands of remediation sites across the country, and are frequently the focus of assessment and remediation efforts. Part 1 of this training course explains
how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1 also explains what LNAPL data can tell you about the LNAPL and site conditions.
Relevant and practical examples are used to illustrate key concepts. Part 2 addresses LNAPL characterization and site conceptual model development as well
as LNAPL recovery evaluation and remedial considerations. Specifically, Part 2 discusses key LNAPL and site data, when and why those data may be important,
and how to get those data. Part 2 also discusses how to evaluate LNAPL recoverability. Part 3 uses the LNAPL conceptual site model (LCSM) approach to identify
the LNAPL concerns or risks and set proper LNAPL remedial objectives and technology-specific remediation goals and performance metrics. Part 3 also provides
an overview of the LNAPL remedial technology selection framework. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live

Updated CLU-IN In Situ Oxidation Focus Area. In situ chemical oxidation, also referred to as ISCO, is an aggressive remediation technology that has been
applied to a wide range of volatile and semivolatile hazardous contaminants, including DNAPL source zones and the dissolved-phase chemicals emanating from
the source zones. The 2010 Superfund Remedy Report (Thirteenth Edition) reports that ISCO was selected as a remedy at 36 Superfund sites during the period 2005
to 2008. Chemical oxidation typically involves reduction/oxidation (redox) reactions that chemically convert hazardous compounds to nonhazardous or
less toxic compounds that are more stable, less mobile, or inert. Redox reactions involve the transfer of electrons from one compound to another. Specifically,
one reactant is oxidized (loses electrons) and one is reduced (gains electrons). The oxidizing agents most commonly used for treatment of hazardous contaminants
in soil and groundwater are hydrogen peroxide, catalyzed hydrogen peroxide, potassium permanganate, sodium permanganate, sodium persulfate, and ozone.
Each oxidant has advantages and limitations, and while applicable to soil contamination and some source zone contamination, they have been applied primarily
toward remediating groundwater. View and use at http://clu-in.org/isco .
Nanotechnology: Applications for Environmental Remediation CLU‐IN Technology Focus Area Fact Sheet. This fact sheet describes a new remediation
technology focus area: Nanotechnology: Applications for Environmental Remediation. The goal of this focus area is to help site owners and other parties involved
in remedial activities understand the current and potential applications of nanotechnology at their sites. Information on this website is organized into
the following categories: Overview, Guidance, Application, Training, and Additional Resources. View or download at http://cluin.org/download/remed/nano-fac ...
Electronic Data Deliverables: The Importance of Receiving Your Site and Project Data Electronically (EPA 542-F-11-010). The purpose of this fact sheet
is to encourage even wider use of Electronic Data Deliverables (EDDs) by explaining their importance and how to ensure that your site data are submitted electronically.
The EDD Fact Sheet Appendix provides supplemental information on what to request in EDDs, how electronic data are shared, examples of data to submit electronically,
and links to EDD guidance (April 2011, 2 pages). View or download at http://clu-in.org/techpubs.htm .
New Triad Profiles Available on the Triad Resource Center Website. New Triad profiles have recently been added to the User Experiences section of the website.
These profiles are concise summaries of successful Triad projects and are backed by a database that can be searched using various criteria such as contaminant,
remedial phase, and technology category. Triad is an innovative approach to data collection and decision-making for hazardous waste site characterization
and remediation, and the U.S. EPA's Triad Resource Center Website (http://www.triadcentral.org/) is a central location for information about the Triad Approach.
The website also offers a wide range of information about the use of the Triad including access to the Triad Community of Practice (CoP), Triad technical resources
and guidance, and user experiences on the use of Triad at federal and private sites. For additional information or to add a Triad profile, contact Cheryl Johnson
at Johnson.Cheryl@epa.gov. View and use at http://www.triadcentral.org/user/profile ... .
