Special Notice  
EPA Small Business Innovation Research (SBIR) Solicitation Open!   
EPA invites small business firms to submit research proposals   
under this Small Business Innovation Research (SBIR)   
Solicitation. EPA is interested in advanced technologies that   
address the following EPA topics: Innovation in Manufacturing,   
Nanotechnology, Green Buildings, Drinking Water and Water   
Monitoring, Water Infrastructure Rehabilitation, Monitoring and   
Control of Air Pollution, Biofuels and Vehicle Emissions   
Reduction, Waste Management and Monitoring and Homeland   
Security. The objective of Phase I is to determine the technical   
feasibility and the preliminary commercialization potential of   
the proposed effort. The maximum dollar amount of awards under   
this Phase I solicitation is $70,000 and the term of performance   
should not exceed six months. The solicitation opened March 20   
and closes May 21. See ... for full   
Upcoming Live Internet Seminars  
ITRC Decontamination and Decommissioning of   
Radiologically-Contaminated Facilities - April 3. 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   
information and to register, see or .  
ITRC Characterization, Design, Construction and Monitoring of   
Bioreactor Landfills - April 10. Bioreactors are landfills where   
controlled addition of non-hazardous liquid wastes, sludges, or   
water accelerates the decomposition of waste and landfill gas   
generation. This training, based on the ITRC's Characterization,   
Design, Construction, and Monitoring of Bioreactor Landfills   
(ALT-3, 2006), teaches the principles used to make critical   
decisions during permitting, operating, and monitoring a   
bioreactor landfill. This training also provides a general   
understanding of the biological degradation of solid wastes   
under aerobic and anaerobic waste conditions and the degradation   
products associated with each process. For more information and   
to register, see or .  
ITRC Risk Assessment and Risk Management: Determination and   
Application of Risk-Based Values - April 17. This training   
course describes the development and application of risk-based   
screening values. The first module provides a review of key risk   
assessment concepts related to risk management. The second   
module focuses on the process by which risk-based levels are   
derived in different states. The third module examines the   
application of risk assessment to remediation operations in two   
case studies providing examples of how risk assessment has   
actually been implemented, based upon research and case studies   
conducted by the ITRC Risk Assessment Resources team. This   
training course describes a number of the reasons behind   
variations in risk-based screening values and their use in risk   
management. For more information and to register, see or .  
Earth Day Green Remediation Panel Session - April 22. As part of   
the U.S. EPA's goal of improved environmental stewardship across   
its programs, the Agency has begun examining opportunities to   
integrate sustainable practices into the decision-making   
processes and implementation strategies used to remediate and   
manage contaminated lands. Three major efforts under this   
umbrella will be discussed in this seminar; 1) Green   
remediation, 2) soil amendments for impaired lands, and 3)   
renewable energy on contaminated lands. For more information and   
to register, see .  
ITRC Protocol for Use of Five Passive Samplers - April 24. This   
training supports the understanding and use of the ITRC Protocol   
for Use of Five Passive Samplers to Sample for a Variety of   
Contaminants in Groundwater (DSP-5, 2007). The five technologies   
included in this document include diffusion samplers,   
equilibrated grab samplers; and an accumulation sampler. The   
training starts with information common to all five samples then   
focuses on each sampler as instructors describe the sampler and   
explain how it works; discuss deployment and retrieval of the   
sampler; highlight advantages and limitations; and present   
results of data comparison studies. For more information and to   
register, see or   
ITRC Vapor Intrusion Pathway: A Practical Guideline - April 29.   
The ITRC Vapor Intrusion Team developed the ITRC Technical and   
Regulatory Guidance document Vapor Intrusion Pathway: A   
Practical Guideline (VI-1, 2007), companion document Vapor   
Intrusion Pathway: Investigative Approaches for Typical   
Scenarios (VI-1A, 2007), and this Internet-based training course   
to be used by regulatory agencies and practitioners alike. This   
training course provides an overview of the vapor intrusion   
pathway and information on the framework (evaluation process),   
investigative tools, and mitigation approaches. The training   
course uses typical scenarios to illustrate the process. For   
more information and to register, see or .   
New Documents and Web Resources  
DNAPL Website. EPA's Office of Superfund Remediation and   
Technology Innovation has released a website that compiles   
available information related to the cleanup of dense   
nonaqueous-phase liquids (DNAPLs) at hazardous waste sites. This   
initial phase addresses the most common DNAPL contaminants:   
chlorinated ethenes (e.g., tetrachloroethene and   
trichloroethene) and multi-component wastes (creosotes, coal   
tars, and heavy oils). Future expansion may include ethers,   
halogenated alkanes, polychlorinated biphenyls, and other   
chemicals that form DNAPLs. With the primary focus on source   
zone cleanup, information is provided for available remediation   
technologies, such as bioremediation, in situ flushing and   
oxidation, and thermal processes. EPA will maintain the website   
by adding new resources as they become available. The website   
was developed in response to a recommendation of the EPA Ground   
Water Task Force (, which identified a need   
for the creation of a comprehensive compilation of DNAPL   
resources. View and use at .  
Brownfields Technology Primer: Vapor Intrusion Considerations   
for Redevelopment (EPA 542-R-08-001). This primer is designed   
for land revitalization stakeholders concerned about vapor   
intrusion, including property owners, municipalities, and real
