> Brownfields Grant Award Announcement
EPA Announces $69.3 Million to Clean Up Contaminated Sites and Revitalize Communities. EPA is announcing new Brownfields grants to provide communities
with funding necessary to assess, clean and redevelop contaminated properties, boost local economies and create jobs while protecting public health. The
245 grantees include tribes and communities in 39 states across the country, funded by EPA's Brownfields Assessment, Revolving Loan Fund, and Cleanup (ARC)
grants and RLF Supplemental Grants. Since the Program's inception, EPA's Brownfields investments have leveraged more than $18.3 billion in cleanup and redevelopment
funding from a variety of public and private sources and have resulted in approximately 75,500 jobs. EPA has awarded 2,008 Assessment grants totaling $480.1
million, 292 Revolving Loan Fund grants totaling $286.1 million, and 838 Cleanup grants totaling $157.6 million. For more information and to view awarded
brownfields grants by state, see http://www.epa.gov/brownfields/news .
> Upcoming Live Internet Seminars
ITRC Biofuels: Release Prevention, Environmental Behavior, and Remediation - June 7, 2012, 11:00AM-1:15PM EDT (15:00-17:15 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 Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment Sites - June 12, 2012, 2:00PM-4:15PM EDT (18:00-20:15
GMT). ITRC's web-based Technical and Regulatory Guidance, Incorporating Bioavailability Considerations into the Evaluation of Contaminated Sediment
Sites (Sed-1, 2011) and associated Internet-based training are intended to assist state regulators and practitioners with understanding and incorporating
fundamental concepts of bioavailability in contaminated sediment management practices. This guidance and training describe how bioavailability considerations
can be used to evaluate exposure at contaminated sediment sites, the mechanisms affecting contaminant bioavailability, available tools used to assess bioavailability,
the proper application of those tools and how bioavailability information can be incorporated into risk-management decisions. This guidance and training
also contain summaries of case studies where bioavailability has been assessed and considered in the contaminated sediment remedial decision making process.
This guidance and training provide insight on how bioavailability assessments can be used to understand, mitigate and manage risk at a contaminated sediment
site, often at a reduced overall project cost. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .
New CLU-IN Mining Sites Webinar Series. This new webinar series will complement the CLU-IN Focus Page on Characterization, Cleanup, and Revitalization
of Abandoned Mining Sites. The webinar series is targeted to site managers, regulatory agencies, consultants, and the general public as a source of relevant
and current information on abandoned mine land issues and available treatment technologies. Potential topics include technology transfer, innovative
and ecological approaches to dealing with mining waste, reuse and recovery technologies, renewable energy on former mine sites, and other related focus areas.
Ideas for other webinar topics are welcome! Please submit your comments to Michele Mahoney at firstname.lastname@example.org . The first webinar in the series will
focus on Technology Transfer and Training Resources for Mining Sites. The webinar will be held on June 13, 2012, 1:00 PM - 3:00 PM, EDT (17:00-19:00 GMT). For
more information and to register, visit http://clu-in.org/mining/events .
ITRC A Decision Framework for Applying Attenuation Processes to Metals and Radionuclides - June 14, 2012, 11:00AM-1:15PM EDT (15:00-17:15 GMT). This training
and the associated ITRC Technical and Regulatory Guidance document, A Decision Framework for Applying Attenuation Processes to Metals and Radionuclides
(APMR-1, 2010), is intended for anyone involved with evaluating, investigating, remediating or managing a site that involves metal and radionuclide contaminants
in groundwater. This training and document provides: introduction to key attenuation processes for metals and radionuclides, information on incorporating
Monitored Natural Attenuation (MNA) into remedial alternatives for metals/rads, and an overview of the decision framework on MNA for metals and radionuclides
in groundwater within the larger evaluation framework of a contaminated site. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live
ITRC Development of Performance Specifications for Solidification/Stabilization - June 26, 2012, 2:00PM-4:15PM EDT (18:00-20:15 GMT). The ITRC technical
and regulatory guidance document Development of Performance Specifications for Solidification/Stabilization (S/S-1, 2011) and associated Internet-based
training provide an approach to assist practitioners and regulators with measuring and determining acceptable S/S performance. This approach developed
by the ITRC Solidification/Stabilization Team provides information for developing, testing, and evaluating appropriate site-specific performance specifications
and the considerations for designing appropriate long-term stewardship programs. In addition, the approach provides useful tools for establishing an appropriate
degree of treatment and regulatory confidence in the performance data to support decision-making. This training and guidance is intended to be beneficial
to anyone involved with CERCLA, RCRA, Brownfields, UST or any other regulatory program where S/S has been selected or implemented as a remedial technology.
